These factors are not intended to represent a complete list of the general or specific factors that could affect the Company. All forward-looking statements speak only as of the date made. All subsequent written and oral forward-looking statements attributable to the Company, or persons acting on its behalf, are expressly qualified in their entirety by the cautionary statements. Except as required by law, the Company undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date on which it is made or to reflect the occurrence of anticipated or unanticipated events or circumstances. Undue reliance should not be placed on these forward-looking statements. Cautionary Note Regarding Exploration Stage Companies Silver Bull is an exploration stage company and does not currently have any known mineral reserves and cannot be expected to have known mineral reserves unless and until a feasibility study is completed for the Sierra Mojada concessions that shows proven and probable mineral reserves. There can be no assurance that the Company’s concessions contain proven and probable mineral reserves and investors may lose their entire investment. See the “Risk Factors” section below. 3 Cautionary Note to U.S. Residents Concerning Disclosure of Mineral Resources Silver Bull is a U.S. domestic issuer for United States Securities and Exchange Commission (“SEC”) purposes, most of its shareholders are U.S. residents, it is required to report its financial results under U.S. Generally Accepted Accounting Principles (“U.S. GAAP”), and its shares of common stock are listed on the Toronto Stock Exchange (the “TSX”) and trade on the OTCQB marketplace. However, because Silver Bull is a reporting issuer in Canada, certain prior regulatory filings required in Canada contain or incorporate by reference therein certain disclosure that satisfies the additional requirements of Canadian securities laws, which differ from the requirements of United States’ securities laws. Unless otherwise indicated, all resource estimates included in those Canadian filings, and in the documents incorporated by reference therein, had been prepared in accordance with Canadian National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”) and the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) classification system. NI 43-101 is a rule developed by the Canadian Securities Administrators which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Canadian standards, including NI 43-101, may differ from the requirements of subpart 1300 of Regulation S-K, as defined in the Glossary of Technical Terms (“S-K 1300”). Thus, resource information contained, or incorporated by reference, in the Company’s Canadian filings, and in the documents incorporated by reference therein, may not be comparable to similar information disclosed by companies reporting mineral reserve and mineral resource information under S-K 1300. The terms “mineral reserve”, “proven mineral reserve” and “probable mineral reserve” are Canadian mining terms as defined in accordance with NI 43-101 and CIM standards. Pursuant to S-K 1300, the SEC now recognizes estimates of “measured mineral resources,” “indicated mineral resources” and “inferred mineral resources.” In addition, the SEC has amended its definitions of “proven mineral reserves” and “probably mineral reserves” to be substantially similar to the corresponding standards of the CIM. Investors are cautioned that while terms are substantially similar to CIM standards, there are differences in the definitions and standards under S-K 1300 and the CIM standards. Accordingly, there is no assurance any mineral reserves or mineral resources that the Company may report as “proven reserves”, “probable reserves”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43-101 will be the same as the reserve or resource estimates prepared under the standards adopted under S-K 1300. Investors are also cautioned that while the SEC now recognizes “measured mineral resources,” “indicated mineral resources” and “inferred mineral resources”, investors should not assume that any part or all of mineral deposits in these categories will ever be converted into reserves. Mineralization described using these terms has a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an “measured mineral resource,” “indicated mineral resource” or “inferred mineral resource” will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable. Disclosure of “contained ounces” in a resource is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute “reserves” by SEC standards as in place tonnage and grade without reference to unit measures. Technical Report Summaries and Qualified Persons The scientific and technical information concerning our mineral projects in this Form 10-K have been reviewed and approved by “qualified persons” under S-K 1300, including our Chief Executive Officer and Director, Timothy Barry and our Director, David Underwood. For a description of the key assumptions, parameters and methods used to estimate mineral reserves and mineral resources included in this Form 10-K, as well as data verification procedures and a general discussion of the extent to which the estimates may be affected by any known environmental, permitting, legal, title, taxation, sociopolitical, marketing or other relevant factors, please review the Technical Report Summaries for each of the Company’s material properties which are included as exhibits to, and incorporated by reference into, this annual report on Form 10-K. 4 The following terms are used throughout this Annual Report on Form 10-K. Glossary of Common Terms Concession Exploration Stage Feasibility Study Formation Mining A grant of a tract of land made by a government or other controlling authority in return for stipulated services or a promise that the land will be used for a specific purpose. A prospect that is not yet in either the development or production stage. An engineering study designed to define the technical, economic, and legal viability of a mining project with a high degree of reliability. A distinct layer of sedimentary rock of similar composition. The process of extraction and beneficiation of mineral reserves to produce a marketable metal or mineral product. Exploration continues during the mining process and, in many cases, mineral reserves are expanded during the life of the mine operations as the exploration potential of the deposit is realized. Ore, Ore Reserve, or Mineable Ore Body The part of a mineral deposit which could be economically and legally extracted or produced at the time of the reserve determination. Mineral Reserves Mineral Resource An estimate of tonnage and grade or quality of indicated and measured mineral resources that, in the opinion of the qualified person, can be the basis of an economically viable project. More specifically, it is the economically mineable part of a measured or indicated mineral resource, which includes diluting materials and allowances for losses that may occur when the material is mined or extracted. A concentration or occurrence of material of economic interest in or on the Earth's crust in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction. A mineral resource is a reasonable estimate of mineralization, taking into account relevant factors such as cut-off grade, likely mining dimensions, location or continuity, that, with the assumed and justifiable technical and economic conditions, is likely to, in whole or in part, become economically extractable. It is not merely an inventory of all mineralization drilled or sampled. Tonne A metric ton which is equivalent to 2,204.6 pounds. PART I Items 1 and 2. BUSINESS AND PROPERTIES Overview and Corporate Structure Silver Bull Resources, Inc. was incorporated in the State of Nevada on November 8, 1993 as the Cadgie Company for the purpose of acquiring and developing mineral properties. The Cadgie Company was a spin-off from its predecessor, Precious Metal Mines, Inc. On June 28, 1996, the Company’s name was changed to Metalline Mining Company (“Metalline”). On April 21, 2011, the Company’s name was changed to Silver Bull Resources, Inc. The Company has not realized any revenues from its planned operations, and is considered an exploration stage company. The Company has not established any reserves with respect to its exploration projects and may never enter into the development stage with respect to any of its projects. The Company is engaged in the business of mineral exploration. It currently owns a number of property concessions in Mexico within a mining district known as the Sierra Mojada District, located in the west–central part of the state of Coahuila, Mexico. Operations are conducted in Mexico through the Company’s wholly-owned subsidiary corporations, Minera Metalin S.A. de C.V. (“Minera Metalin”), and Minas de Coahuila SBR S.A. de C.V (“Minas”). In April 2010, Metalline Mining Delaware, Inc., a wholly-owned subsidiary incorporated in the State of Delaware, was merged with and into Dome Ventures Corporation (“Dome”), a Delaware corporation. As a result, Dome became a wholly-owned subsidiary of Silver Bull. Dome has a wholly-owned subsidiary, Dome Asia Inc. (“Dome Asia”), which is incorporated in the British Virgin Islands. On June 5, 2015, the Company announced its decision to voluntarily delist its shares of common stock from the NYSE MKT due to costs associated with the continued listing and NYSE MKT exchange rules regarding maintenance of a minimum share price. On June 29, 2015, the Company’s shares began trading on the OTCQB marketplace operated by OTC Markets Group. The Company’s shares of common stock continue to trade on the TSX. 5 On August 12, 2020, the Company entered into an option agreement (the “Beskauga Option Agreement”) with Copperbelt AG, a corporation existing under the laws of Switzerland (“CB Parent”), and Dostyk LLP, an entity existing under the laws of Kazakhstan and a wholly-owned subsidiary of CB Parent (the “CB Sub,” and together with CB Parent, “CB”), pursuant to which the Company had the exclusive right and option (the “Beskauga Option”) to acquire CB’s right, title and 100% interest in the Beskauga property located in Kazakhstan (the “Beskauga Property”), which consists of the Beskauga Main project (the “Beskauga Main Project”) and the Beskauga South project (the “Beskauga South Project,” and together the Beskauga Main Project, the “Beskauga Project”). The transaction contemplated by the Beskauga Option Agreement closed on January 26, 2021. On February 5, 2021, Arras Minerals Corp. (“Arras”) was incorporated in British Columbia, Canada, as a wholly-owned subsidiary of Silver Bull. On March 19, 2021, pursuant to an asset purchase agreement with Arras, Silver Bull transferred its right, title and interest in and to the Beskauga Option Agreement, among other things, to Arras. On September 24, 2021, Silver Bull distributed to its shareholders one Arras common share for each Silver Bull share held by such shareholders, or 34,547,838 Arras common shares in total (the “Distribution”). Upon completion of the Distribution, the Company retained 1,452,162 Arras common shares, or approximately 4% of the outstanding Arras common shares, as a strategic investment, and Arras became a stand-alone company. The financial results of Arras are included in the Company’s consolidated statement of operations for the period from February 5, 2021 to September 24, 2021, the date of the Distribution. The Company’s efforts and expenditures have been and are expected to be concentrated in the exploration of properties, principally the Sierra Mojada property located in Coahuila, Mexico (the “Sierra Mojada Property”). Silver Bull has not determined whether its exploration properties contain ore reserves that are economically recoverable. The ultimate realization of investment in exploration properties is dependent upon the success of future property sales, the existence of economically recoverable reserves, and the Company’s ability to obtain financing or make other arrangements for exploration, development and future profitable production activities. The ultimate realization of the Company’s investment in exploration properties cannot be determined at this time. South32 Option Agreement On June 1, 2018, the Company’s subsidiaries Minera Metalin and Contratistas entered into an earn-in option agreement (the “South32 Option Agreement”) with South32 International Investment Holdings Pty Ltd (“South32”), a wholly owned subsidiary of South32 Limited (ASX/JSE/LSE: S32), whereby South32 was able to obtain an option to purchase 70% of the shares of Minera Metalin and Contratistas (the “South32 Option”). On October 11, 2019, the Company and subsidiary Minera Metalin issued a notice of force majeure to South32 pursuant to the South32 Option Agreement. Due to a blockade by a cooperative of local miners called Sociedad Cooperativa de Exploración Minera Mineros Norteños, S.C.L. (“Mineros Norteños”), all work was halted on the Sierra Mojada Property. The notice of force majeure was issued because of the blockade’s impact the Company and subsidiary Minera Metalin’s ability to perform their obligations under the South32 Option Agreement. Pursuant to the South32 Option Agreement, any time period provided for in the South32 Option Agreement was to be generally extended by a period equal to the period of delay caused by the event of force majeure. On August 31, 2022, the South32 Option Agreement was mutually terminated by South32 and the Company. South32 paid $518,000 to the Company as a final payment for the exploration costs occurred by the Company during the blockade and released South32 from all claims as the date of termination. As of January 26, 2023, the blockade by Mineros Norteños at, on and around the Sierra Mojada Property is ongoing. Sierra Mojada Project Location, Access and Infrastructure The Sierra Mojada Project is located within a mining district known as the Sierra Mojada District. The Sierra Mojada District is located in the west–central part of the state of Coahuila, Mexico, near the Coahuila-Chihuahua state border approximately 200 kilometers south of the Big Bend of the Rio Grande River. The principal mining area extends for approximately five kilometers in an east-west direction along the base of the precipitous, 1,000-meter high Sierra Mojada Range. The Sierra Mojada Project site is situated to the south of the village of Esmeralda, on the northern side of a major escarpment that forms the northern margin of the Sierra Mojada range. In general, the site is approximately 1,500 meters above sea level. The project is accessible by paved road from the city of Torreon, Coahuila, which lies approximately 250 kilometers to the south. Esmerelda is served by a rail spur of the Coahuila Durango railroad. There is an airstrip east of Esmeralda, although its availability is limited, and another airstrip at the nearby Peñoles plant, which the Company can use occasionally. The Sierra Mojada District has high voltage electric power supplied by the national power company, Comisión Federal de Electricidad, C.F.E., and is supplied water by the municipality of Sierra Mojada. Although power levels are sufficient for current operations and exploration, future development of the project, if any, may require additional power supplies to be sourced. Sierry Mojada Project facilities in Mexico include offices, accommodation for employees, workshops, warehouse buildings and exploration equipment located at Calle Mina #1, La Esmeralda, Coahuila, Mexico. 6 The map below shows the location of the Sierra Mojada Project: 7 The map below shows the concessions of the Sierra Mojada Project: Property History Silver and lead were first discovered by a foraging party in 1879, and mining through 1886 consisted of native silver, silver chloride, and lead carbonate ores. After 1886, silver-lead-zinc-copper sulphide ores within limestone and sandstone units were produced. No accurate production history has been found for historical mining during this period. Approximately 95 years ago, zinc silicate and zinc carbonate minerals (“Zinc Manto Zone”) were discovered underlying the silver-lead mineralized horizon. The Zinc Manto Zone is predominantly zinc dominated, but with subordinate lead-rich manto and is principally situated in the footwall rocks of the Sierra Mojada Fault System. Since discovery and until 1990, zinc, silver, and lead ores were mined from various mines along the strike of the deposit, including from the Sierra Mojada Property. Ores mined from within these areas were hand-sorted, and the concentrate shipped mostly to smelters in the United States. Activity during the period of 1956 to 1990 consisted of operations by the Mineros Norteños and operations by individual owners and operators of pre-existing mines. The Mineros Norteños operated the San Salvador, Encantada, Fronteriza, Esmeralda, and Parrena mines, and shipped oxide zinc ore to Zinc National’s smelter in Monterrey, while copper and silver ore were shipped to smelters in Mexico and the United States. It is estimated that over 45 mines have produced ore from underground workings throughout the approximately five kilometers by two-kilometer area that comprises the Sierra Mojada District. It is estimated that since its discovery in 1879, the Sierra Mojada District has produced approximately 10 million tons of silver, zinc, lead and copper ore. The Sierra Mojada District does not have a mill to concentrate ore, and all mining conducted thus far has been limited to selectively mined ore of sufficient grade to direct ship to smelters. The Company believes that mill-grade mineralization that was not mined remains available for extraction. No mining operations are currently active within the area of the Sierra Mojada District, except for a dolomite quarry by Peñoles near Esmeralda. In the 1990s, Kennecott Copper Corporation (“Kennecott”) had a joint venture agreement with USMX, Inc. (“USMX”) involving its Sierra Mojada concessions. Kennecott terminated the joint venture in approximately 1995. Metalline entered into a Joint Exploration and Development Agreement with USMX in July 1996 involving USMX’s Sierra Mojada concessions. In 1998, Metalline purchased the Sierra Mojada and the USMX concessions, and the joint exploration and development agreement was terminated. Metalline also purchased certain other concessions during this time and conducted exploration for copper and silver mineralization from 1997 through 1999. 8 Title and Ownership Rights The Sierra Mojada Project is comprised of 20 concessions consisting of 6,496 hectares (about 16,052 acres). The Company periodically obtains additional concessions in the Sierra Mojada Project area, and whether it will continue to hold these additional concessions will depend on future exploration work and exploration results and its ability to obtain financing. As in prior years, the Company continually assesses its concession ownership, and may terminate its rights to certain concessions holdings. Each mining concession enables Silver Bull to explore the underlying concession in consideration for the payment of a semi-annual fee to the Mexican government and completion of certain annual assessment work. Annual assessment work in excess of statutory annual requirements can be carried forward and applied to future periods. Ownership of a concession provides the owner with exclusive exploration and exploitation rights to all minerals located on the concessions, but does not include the surface rights to the real property. Therefore, the Company will need to negotiate any necessary agreements with the appropriate surface landowners if it is determined that a mining operation is feasible for the concessions. The Company owns surface rights to five lots in the Sierra Mojada Property (Sierra Mojada lot #1, #3, #4, #6 and #7) but anticipates that it will be required to obtain additional surface rights if it is determined that a mining operation is feasible. Geology and Mineralization The Sierra Mojada concessions contain a mineral system which can be separated into two distinct zones: a silver-rich zone (the “Silver Zone”) and a zinc-rich zone (the “Zinc Zone”). These two zones lie along the Sierra Mojada Fault which trends east–west along the base of the Sierra Mojada range. The majority of the mineralization identified to date is seen as oxide, which has been derived from primary “sulphide” bodies that have been oxidized and remained in situ or remobilized into porous and fractured rock along the Sierra Mojada Fault. The formation of the Silver Zone and the Zinc Zone is a reflection of the mobility of the metals in the ground water conditions at Sierra Mojada. The geology of the Sierra Mojada District is composed of a Cretaceous limestone and dolomite sequence sitting on top of the Jurassic “San Marcos” red sediments. This sedimentary sequence was subsequently intruded by Tertiary volcanics, which are considered to be responsible for the mineralization seen at Sierra Mojada. Historical mines are dry, and the rocks are competent for the most part. The Company believes that the thickness and attitude of the mineral resources could potentially be amenable to high volume mechanized mining methods and low-cost production. Sierra Mojada Technical Report Summary (2023) On January 24, 2023, Archer, Cathro & Associates (1981) Limited and Timothy Barry delivered a technical report summary (the “Sierra Mojada 2023 TRS”) on the silver and zinc mineralization at the Sierra Mojada Project in accordance with subpart 1300 of Regulation S-K. The Sierra Mojada 2023 TRS supersedes the prior mineral resources estimate released by the Company on October 30, 2018. The Sierra Mojada 2023 TRS includes an update on the silver and zinc mineralization which was estimated from 1,336 diamond drill holes, 24 reverse circulation drill holes, 9,027 channel samples and 2,346 underground long holes. Using a net smelter return (“NSR”) economic cut-off, the Sierra Mojada 2023 TRS indicates mineral resources in the optimized pit of 70.4 million tonnes at an average silver grade of 38.6 grams/tonne silver, an average zinc percentage of 3.4%, an average copper percentage of 0.04% and an average lead percentage of 0.3%. The Sierra Mojada Report used a $13.50/tonne NSR cut-off grade and assumed a silver price of $18.00/ounce and a zinc price of $1.20/pound based on a five year average. Sampling, Analysis, Quality Control and Security The Company’s activities conform to mining industry standard practices and follow the Best Practices Guidelines of the Canadian Institute of Mining, Metallurgy, and Petroleum (CIM). Sampling is directed and supervised by trained and experienced geologists. Drill core and other samples are processed and logged using industry standard methods. Standard samples, duplicates and blanks are periodically entered into the stream of samples submitted for assays, and campaigns of re-sampling and duplicate analyses and round-robin inter-laboratory validations are conducted periodically. ALS Chemex – Vancouver (“ALS Chemex”) laboratory is the Company’s independent primary laboratory. ALS Chemex is ISO 9001:2000 certified. All analytical results that are used in resource models are exclusively from the independent primary laboratory. 9 Silver Bull’s consultants perform technical audits of its operations, including a formal quality assurance/quality control (“QA/QC”) program, and recommend improvements as needed. A systematic program of duplicate sampling and assaying of representative samples from previous exploration activities was completed in 2010 under the direction and control of the Company’s consultants. Results of this study acceptably confirm the values in the project database used for resource modeling. The Company formerly operated a sample preparation and an analytical laboratory at the project that prepared samples for shipment, performed QA/QC analyses to ensure against cross-contamination of samples during preparation and removed most low-value samples from the flow to the primary laboratory. For cost and other reasons, the internal laboratory has been shut down. Prior Exploration Activities Exploration efforts have been focused on two primary locations: the Silver Zone and the Zinc Zone. As further described below, various exploration activities have been conducted at the Sierra Mojada Project; however, to date, the Company has not established any reserves, and the project remains in the exploration stage and may never enter the development stage. Prior to 2008, exploration efforts largely focused on the Zinc Zone with surface and underground drilling. In fiscal year 2009, exploration activities were scaled back and administrative costs were reduced to conserve capital while the Company tried to secure additional sources of capital resources. After closing the transaction with Dome in April 2010, exploration activities at Sierra Mojada primarily focused on the Silver Zone, which lies largely at surface. By the end of calendar 2018, approximately 101,000 meters of diamond drilling from surface and 10,000 meters of underground drilling had been completed. The silver contained within the Silver Zone is seen primarily as silver halide minerals. The zinc contained within the Zinc Zone is contained mostly in the mineral hemimorphite and, to a lesser amount, in the mineral smithsonite. 2023 Exploration Activities In January 2023, the Company’s board of directors approved an exploration budget for the Sierra Mojada Property of $0.3 million and $0.7 million for general and administrative expenses for calendar year 2023. Due to the blockade by Mineros Norteños previously mentioned under the “South32 Option Agreement” section of this Form 10-K, all work at the Sierra Mojada Property remains halted. 2022 Drilling During the year ended October 31, 2022, no drilling was conducted as the drilling program remained halted due to the continuing blockade. Airborne Geophysics Between September 2018 and November 2018, a 5,297 line kilometer helicopter-borne Versatile Time Domain Electro Magnetic (VTEM) and Magnetic Geophysical Survey was completed over the Sierra Mojada Property. The results of this survey aided in refining the design of the drilling program. 2023 Exploration Program The focus of the 2023 calendar year exploration program on the Sierra Mojada Property will be to resolve the blockade and maintain property concessions. The continued exploration of the Sierra Mojada Property ultimately will require the Company to raise additional capital, identify other sources of funding or identify a strategic partner. Metallurgical Studies In May 2015, a selection of high-grade zinc material samples were shipped to a lab in Denver, Colorado for “fine bubble” flotation test work and to a group in Australia to assess their proprietary hydrometallurgy process. Previous test work completed by Silver Bull using mechanical flotation has shown an 87% recovery of zinc from the white zinc zone to produce a rough concentrate of 43% zinc, and a 72.5% recovery of zinc from the red zinc zone to produce a rough concentrate of 30% zinc. The “fine bubble” flotation test work that was performed did not improve recovery, but based on analysis of the results, it was determined that the “fine bubble” flotation test process may be able to be adjusted to improve recovery. Further testing is not planned at this time. 10 In addition, a metallurgical program was previously conducted to test the recovery of (i) the silver mineralization using the agitation cyanide leach method and (ii) the zinc mineralization using the SART process (sulfidization, acidification, recycling, and thickening). The test work on the Silver Zone focused on cyanide leach recovery of the silver using “Bottle Roll” tests to simulate an agitation leach system and to determine the recovery of (A) low-grade zinc that occurs in the Silver Zone and (B) high-grade zinc from the Zinc Zone that had been blended with mineralization from the Silver-rich Zone to the leach solution. The silver was recovered from the cyanide leach solution using the Merrill Crowe technique, and the zinc was recovered from the leach solution using the SART process. The SART process is a metallurgical process that regenerates and recycles the cyanide used in the leaching process of the silver and zinc and allows for the recovery of zinc that has been leached by the cyanide solution. The results showed an overall average silver recovery of 73.2%, with peak values of 89.0% and an overall average zinc recovery of 44% in the Silver Zone. Mineral Resources Under S-K 1300, a mineral resource is defined as “a concentration or occurrence of material of economic interest in or on the Earth’s crust in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction.” A mineral resource is a “reasonable estimate of mineralization, taking into account relevant factors such as cut-off grade, likely mining dimensions, location or continuity, that, with the assumed and justifiable technical and economic conditions, is likely to, in whole or in part, become economically extractable. It is not merely an inventory of all mineralization drilled or sampled.” More information supporting assumptions, methodologies, and procedures can be found in the Technical Report Summary filed as Exhibit 96.1 to this Form 10-K.

From January 1, 2022 to December 31, 2022 the price of silver ranged from a low of $17.77 per troy ounce to a high of $26.17 per troy ounce, and from January 1, 2022 to December 31, 2022 the price of zinc ranged from a low of $2,967 per tonne to a high of $4,360 per tonne. Silver and zinc prices are affected by many factors beyond the Company’s control, including prevailing interest rates and returns on other asset classes, expectations regarding inflation, speculation, currency values, governmental decisions regarding the disposal of precious metals stockpiles, global and regional demand and production, political and economic conditions and other factors. The competitive nature of the business and the risks faced are discussed further in the “Risk Factors – Risks Related to the Company’s Business” section below. The following tables set forth, for the periods indicated, high and low silver and zinc prices on the London Metal Exchange in U.S. dollars per troy ounce and per tonne, respectively. On October 31, 2022, the closing price of silver was $19.17 per troy ounce. On October 31, 2022, the closing price of zinc was $2,967 per tonne. Year 2015 2016 2017 2018 2019 2020 2021 2022 Year 2015 2016 2017 2018 2019 2020 2021 2022 Silver (per troy ounce) Zinc (per tonne) High $18.23 $20.71 $18.56 $17.52 $19.31 $28.89 $29.58 $26.17 High $2,281 $2,566 $3,264 $3,533 $2,932 $2,780 $3,399 $4,360 Low $13.71 $13.58 $15.22 $13.97 $14.38 $12.00 $21.52 $17.77 Low $1,528 $1,520 $2,573 $2,434 $2,272 $1,903 $2,705 $2,967 Competition The mining industry is highly competitive. Silver Bull competes with other mining and exploration companies in the acquisition and exploration of mineral properties. There is competition for a limited number of mineral property acquisition opportunities, some of which is with other companies having substantially greater financial resources, staff and facilities than the Company does. As a result, there may be difficulty acquiring attractive exploration properties, staking claims related to the Company’s properties and exploring properties. The Company’s competitive position depends upon its ability to successfully and economically acquire and explore new and existing mineral properties. Government Regulation Mineral exploration activities are subject to various national, state/provincial, and local laws and regulations, which govern prospecting, development, mining, production, exports, taxes, labor standards, occupational health, waste disposal, protection of the environment, mine safety, hazardous substances and other matters. Similarly, if any of the Company’s properties are developed and/or mined, those activities are also subject to significant governmental regulation and oversight. Silver Bull plans to obtain the licenses, permits and other authorizations currently required to conduct its exploration programs. The Company believes that it is in compliance in all material respects with applicable mining, health, safety and environmental statutes and the regulations applicable to the mineral interests held in Mexico. Environment Regulations The Company’s activities are subject to various national and local laws and regulations governing protection of the environment. These laws are continually changing and, in general, are becoming more restrictive. Silver Bull intends to conduct business in a way that safeguards public health and the environment and is in compliance with applicable laws and regulations. 12 Changes to current state or federal laws and regulations in Mexico could, in the future, require additional capital expenditures and increased operating and/or reclamation costs. Although the Company is unable to predict what additional legislation, if any, might be proposed or enacted, additional regulatory requirements could impact the economics of its projects. During fiscal year 2022, Silver Bull had no material environmental incidents or non-compliance with any applicable environmental regulations. Employees Silver Bull has four employees, all of whom work full time. Minera Metalin, its wholly-owned operating subsidiary in Mexico, currently has one full-time employee. Corporate Offices Silver Bull’s corporate office is located at 777 Dunsmuir Street, Suite 1605, Vancouver, British Columbia, Canada V7Y 1G6, telephone number is (604) 687-5800. Available Information The Company maintains a website at http://www.silverbullresources.com. The information on the website is not incorporated by reference in this Annual Report on Form 10-K. The Company makes available on or through its website certain reports and amendments to those reports that are filed with or furnished to the SEC in accordance with the Exchange Act. Readers may also obtain this information from the SEC’s website, http://www.sec.gov. Item 1A. RISK FACTORS A purchase of the Company’s securities involves a high degree of risk. The Company’s business or operating or financial condition could be harmed due to any of the following risks. Accordingly, investors should carefully consider these risks in making a decision as to whether to purchase, sell or hold securities of the Company. In addition, investors should note that the risks described below are not the only risks facing the Company. Additional risks not presently known to the Company, or risks that do not seem significant today, may impair business operations in the future. Readers should carefully consider the risks described below, as well as the other information contained in this Annual Report on Form 10-K and the documents incorporated by reference herein, before making a decision to invest in securities of the Company. Risk factors are grouped into the following categories: Risks Relating to the Company’s Business; Risks Relating to the Mineral Exploration Industry; and Risks Relating to the Company’s Common Stock; RISKS RELATING TO THE COMPANY’S BUSINESS: There is substantial doubt about whether the Company can continue as a going concern. To date, the Company has earned no revenues and has incurred accumulated net losses of $137,394,000. In addition, the Company has limited financial resources. As of October 31, 2022, the Company had cash and cash equivalents of $887,000 and working capital of $620,000. Therefore, continuation as a going concern is dependent upon achieving a future financing or a strategic transaction. However, there is no assurance that the Company will have the ability to be successful pursuing a financing or strategic transaction. Accordingly, there is substantial doubt as to whether existing cash resources and working capital are sufficient to enable the Company to continue its operations for the next 12 months as a going concern. Ultimately, in the event that the Company cannot obtain additional financial resources, or achieve profitable operations, it may have to liquidate its business interests and investors may lose their investment. The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. Continued operations are dependent on the ability to obtain additional financial resources or generate profitable operations. Such additional financial resources may not be available or may not be available on reasonable terms. The consolidated financial statements do not include any adjustments that may result from the outcome of this uncertainty. Such adjustments could be material. 13 The Company may have difficulty meeting its current and future capital requirements. The Company’s management and the board of directors monitor overall costs and expenses and, if necessary, adjust programs and planned expenditures in an attempt to ensure that the Company has sufficient operating capital. The Company continues to evaluate its costs and planned expenditures for its ongoing exploration efforts at the Sierra Mojada Project. As of October 31, 2022, the Company had cash and cash equivalents of $887,000. Even with the successful additional financial resources, the continued exploration and possible development of the Sierra Mojada Project will require significant amounts of additional capital. If the Company is unable to fund future operations by way of financings, including public or private offerings of equity or debt securities, it will need to reorganize or significantly reduce its operations, which may result in an adverse impact on the Company’s business, financial condition and exploration activities. The Company does not have a credit, off-take or other commercial financing arrangement in place that would finance continued evaluation or development of the Sierra Mojada Project, and the Company believes that securing credit for these projects may be difficult. Moreover, equity financing may not be available on attractive terms and, if available, will likely result in significant dilution to existing stockholders. The Company is an exploration stage mining company with no history of operations. The Company is an exploration stage enterprise engaged in mineral exploration in Mexico. The Company has a very limited operating history and is subject to all the risks inherent in a new business enterprise. As an exploration stage company, it may never enter the development and production stages. To date, the Company has had no revenues and have relied upon equity financing, South32 funding and sale of investments to fund its operations. The likelihood of success must be considered in light of the problems, expenses, difficulties, complications, and delays frequently encountered in connection with an exploration stage business, and the competitive and regulatory environment in which the Company operates and will operate, such as under-capitalization, personnel limitations, and limited financing sources. The Company has no commercially mineable ore body. No commercially mineable ore body has been delineated on the Sierra Mojada Project, nor have the Company’s properties been shown to contain proven or probable mineral reserves. Investors should not assume that the projections contained in the Sierra Mojada Report will ever be realized. The Company cannot guarantee that any mineral deposits identified on the Sierra Mojada Project will qualify as an ore body that can be legally and economically exploited or that any particular level of recovery of silver, zinc or other minerals from discovered mineralization will in fact be realized. Most exploration projects do not result in the discovery of commercially mineable ore deposits. Even if the presence of reserves is established at a project, the legal and economic viability of the project may not justify exploitation. Mineral resource estimates may not be reliable. There are numerous uncertainties inherent in estimating quantities of mineral resources such as silver, zinc, lead, and copper, including many factors beyond the Company’s control, and no assurance can be given that the recovery of mineral resources will be realized. In general, estimates of mineral resources are based upon a number of factors and assumptions made as of the date on which the estimates were determined, including: geological and engineering estimates that have inherent uncertainties; the assumed effects of regulation by governmental agencies; the judgment of the engineers preparing the estimate; estimates of future metals prices and operating costs; the quality and quantity of available data; the interpretation of that data; and the accuracy of various mandated economic assumptions, all of which may vary considerably from actual results. All estimates are, to some degree, uncertain. For these reasons, estimates of the recoverable mineral resources prepared by different engineers or by the same engineers at different times may vary substantially. As such, there is significant uncertainty in any mineral resource estimate, and actual deposits encountered and the economic viability of a deposit may differ materially from the Company’s estimates. 14 The Company’s business plan is highly speculative, and its success largely depends on the successful exploration of the Sierra Mojada concessions. The Company’s business plan is focused on exploring the Sierra Mojada concessions to identify reserves and, if appropriate, to ultimately develop each property. Although the Company has reported mineral resources on the Sierra Mojada Project, it has not established any reserves and remains in the exploration stage. The Company may never enter the development or production stage. Exploration of mineralization and determination of whether the mineralization might be extracted profitably is highly speculative, and it may take a number of years until production is possible, during which time the economic viability of the project may change. Substantial expenditures are required to establish reserves, extract metals from ore and construct mining and processing facilities. The Sierra Mojada Project is subject to all of the risks inherent in mineral exploration and development. The economic feasibility of any mineral exploration and/or development project is based upon, among other things, estimates of the size and grade of mineral reserves, proximity to infrastructures and other resources (such as water and power), anticipated production rates, capital and operating costs, and metals prices. To advance from an exploration project to a development project, the Company will need to overcome various hurdles, including completing favorable feasibility studies, securing necessary permits, and raising significant additional capital to fund activities. There can be no assurance that the Company will be successful in overcoming these hurdles. Because of the Company’s focus on the Sierra Mojada Project and its proximity to Torreon, Mexico, the success of its operations and profitability may be disproportionately exposed to the impact of adverse conditions unique to the region. Due to the Company’s history of operating losses, it is uncertain that it will be able to maintain sufficient cash to accomplish its business objectives. During the fiscal years ended October 31, 2022 and 2021 the Company incurred net losses of $3,168,000 and $2,448,000 respectively. At October 31, 2022, the Company had stockholders’ equity of $5,867,000 and cash and cash equivalents of $887,000. Significant amounts of capital will be required to continue to explore and potentially develop the Sierra Mojada concessions. The Company is not engaged in any revenue producing activities, and does not expect to be in the near future. Currently, potential sources of funding consist of the sale of additional equity securities, entering into joint venture agreements or selling a portion of the Company’s interests in its assets. There is no assurance that any additional capital that the Company will require will be obtainable on terms acceptable to it, if at all. Failure to obtain such additional financing could result in delays or indefinite postponement of further exploration of the projects. Additional financing, if available, will likely result in substantial dilution to existing stockholders. Exploration activities require significant amounts of capital that may not be recovered. Mineral exploration activities are subject to many risks, including the risk that no commercially productive or extractable resources will be encountered. There can be no assurance that the Company’s activities will ultimately lead to an economically feasible project or that it will recover all or any portion of its investment. Mineral exploration often involves unprofitable efforts, including drilling operations that ultimately do not further exploration efforts. The cost of minerals exploration is often uncertain, and cost overruns are common. Drilling and exploration operations may be curtailed, delayed or canceled as a result of numerous factors, many of which are beyond the Company’s control, including title problems, weather conditions, protests, compliance with governmental requirements, including permitting issues, and shortages or delays in the delivery of equipment and services. The Company’s financial condition could be adversely affected by changes in currency exchange rates, especially between the U.S. dollar and each of the Mexican peso (“$MXN”) and the Canadian dollar (“$CDN”) given its focus on the Sierra Mojada Project in Mexico and the corporate office in Vancouver, Canada. The Company’s financial condition is affected in part by currency exchange rates, as portions of its exploration costs in Mexico and general and administration costs in Canada are denominated in the local currency. A weakening U.S. dollar relative to the $MXN and $CDN will have the effect of increasing exploration costs and general and administration costs while a strengthening U.S. dollar will have the effect of reducing exploration costs and general and administration costs. The exchange rates between the $CDN and the U.S. dollar and between the $MXN and U.S. dollar have fluctuated widely in response to international political conditions, general economic conditions and other factors beyond the Company’s control. The Company’s success depends on developing and maintaining relationships with local communities and other stakeholders. The Company’s ongoing and future success depends on developing and maintaining productive relationships with the communities surrounding its operations and other stakeholders in its operating locations. The Company believes that its operations can provide valuable benefits to surrounding communities, in terms of direct employment, training and skills development. In addition, the Company seeks to maintain its partnerships and relationships with local communities and stakeholders in a variety of ways, including in-kind contributions, sponsorships and donations. Notwithstanding ongoing efforts, local communities and stakeholders can become dissatisfied with the Company’s activities or the level of benefits provided, which may result in legal or administrative proceedings, civil unrest, protests, direct action or campaigns against the Company, such as the blockade by Mineros Norteños that caused the halt of all work on the Sierra Mojada Property. Any such occurrences, including the blockade, could materially and adversely affect the Company’s financial condition, results of operations and cash flows. 15 The Company shares certain key officers and directors with Arras, which means that those officers do not devote their full time and attention to its affairs, and the overlap may give rise to conflicts of interest. The Company’s Chief Executive Officer, Timothy Barry, President, Darren Klinck, and Chief Financial Officer, Christopher Richards also serve as Chief Executive Officer, President, , and Chief Financial Officer of Arras, respectively. As a result, the Company’s executive officers do not devote their full time and attention to the Company’s affairs. There may be circumstances in which the Company’s executive officers are compelled to spend a significant portion of their time and attention to Arras’ affairs, which may mean that they are unable to devote sufficient time to the Company’s affairs. Furthermore, the Company’s Chairman, Brian Edgar, also serves as Chairman of Arras, and three members of the board of directors (including Timothy Barry and Brian Edgar) are also directors of Arras. The overlapping officers and directors may have actual or apparent conflicts of interest with respect to matters involving or affecting each company. For example, conflicts may arise if there are issues or disputes under commercial arrangements that may exist between Arras and the Company. Any failure of the directors or officers of the Company to address these conflicts in an appropriate manner or to allocate opportunities that they become aware of to the Company could have a material adverse effect on the Company’s business, financial condition, results of operations, cash flows or prospects. The Company needs and relies upon key personnel. Presently, the Company employs a limited number of full-time employees, utilizes outside consultants, and in large part relies on the efforts of its officers and directors. Success will depend, in part, upon the ability to attract and retain qualified employees. In particular, the Company has only three executive officers: Timothy Barry, Darren Klinck and Christopher Richards, and the loss of the services of any of these would adversely affect the Company’s business. The Company is exposed to information systems and cybersecurity risks. The Company’s information systems (including those of any of its counterparties) may be vulnerable to the increasing threat of continually evolving cybersecurity risks. Unauthorized parties may attempt to gain access to these systems or information through fraud or other means of deception. The Company’s operations depend, in part, on how well it and its counterparties protect networks, equipment, information technology systems and software against damage from threats. The failure of information systems or a component of information systems could, depending on the nature of any such failure, adversely impact the Company’s reputation and results of operations. There can be no assurance that the Company or its counterparties will not incur such losses in the future. The Company’s risk and exposure to these matters cannot be fully mitigated because of, among other things, the evolving nature of these threats. As a result, cybersecurity and the continued development and enhancement of controls, processes and practices designed to protect systems, computers, software, data and networks from attack, damage or unauthorized access remain an area of attention. The Company’s operations may be disrupted, and its financial results may be adversely affected, by global outbreaks of contagious diseases, including the coronavirus (COVID-19) pandemic. Global outbreaks of contagious diseases, including the December 2019 outbreak of a strain of coronavirus (COVID-19), have the potential to significantly and adversely impact the Company’s operations and business. On March 11, 2020, the World Health Organization recognized COVID-19 as a global pandemic. Pandemics or disease outbreaks such as the COVID-19 outbreak may have a variety of adverse effects on the Company’s business, including by depressing commodity prices and the market value of its securities and limiting the ability of management to meet with potential financing sources. The spread of COVID-19 has had, and continues to have, a negative impact on the financial markets, which may impact the Company’s ability to obtain additional financing in the near term. A prolonged downturn in the financial markets could have an adverse effect on the Company’s business, results of operations and ability to raise capital. 16 RISKS RELATING TO THE MINERAL EXPLORATION INDUSTRY: There are inherent risks in the mineral exploration industry. The Company is subject to all of the risks inherent in the minerals exploration industry, including, without limitation, the following: competition from a large number of companies, most of which are significantly larger than the Company, in the acquisition, exploration, and development of mining properties; the possible inability to raise enough money to pay the fees and taxes and perform the labor necessary to maintain the Company’s concessions in good status; exploration for minerals is highly speculative, involves substantial risks and is frequently unproductive, even when conducted on properties known to contain significant quantities of mineralization, and the Company’s exploration projects may not result in the discovery of commercially mineable deposits of ore; the probability of an individual prospect ever having reserves that meet the requirements for reporting under S-K 1300 is remote, and any funds spent on exploration may be lost; the Company’s operations are subject to a variety of existing laws and regulations relating to exploration and development, permitting procedures, safety precautions, property reclamation, employee health and safety, air quality standards, pollution and other environmental protection controls, and it may not be able to comply with these regulations and controls; and a large number of factors beyond the Company’s control, including fluctuations in metal prices, inflation, and other economic conditions, will affect the economic feasibility of mining. Metals prices are subject to extreme fluctuation. The Company’s activities are influenced by the prices of commodities, including silver, zinc, lead, copper and other metals. These prices fluctuate widely and are affected by numerous factors beyond the Company’s control, including interest rates, expectations for inflation, speculation, currency values (in particular, the strength of the U.S. dollar), global and regional demand, political and economic conditions and production costs in major metal-producing regions of the world. The Company’s ability to establish reserves through its exploration activities, its future profitability and long-term viability depend, in large part, on the market prices of silver, zinc, lead, copper and other metals. The market prices for these metals are volatile and are affected by numerous factors beyond the Company’s control, including: global or regional consumption patterns; supply of, and demand for, silver, zinc, lead, copper and other metals; speculative activities and producer hedging activities; expectations for inflation; political and economic conditions; and supply of, and demand for, consumables required for production. Future weakness in the global economy could increase volatility in metals prices or depress metals prices, which could in turn reduce the value of the Company’s properties, make it more difficult to raise additional capital, and make it uneconomical for it to continue its exploration activities. There are inherent risks with foreign operations. The Company’s business activities are primarily conducted in Mexico, and as such, its activities are exposed to various levels of foreign political, economic and other risks and uncertainties. These risks and uncertainties include, but are not limited to, terrorism, hostage taking, military repression, extreme fluctuations in currency exchange rates, high rates of inflation, labor unrest, war or civil unrest, expropriation and nationalization, renegotiation or nullification of existing concessions, licenses, permits, approvals and contracts, illegal mining, changes in taxation policies, restrictions on foreign exchange and repatriation, changing political conditions (including, potential instability if the United States withdraws from the United States-Mexico-Canada Agreement), currency controls and governmental regulations that favor or require the rewarding of contracts to local contractors or require foreign contractors to employ citizens of, or purchase supplies from, a particular jurisdiction. 17 Changes, if any, in mining or investment policies or shifts in political attitude in Mexico may adversely affect the Company’s exploration and possible future development activities. The Company may also be affected to varying degrees by government regulations with respect to, but not limited to, foreign investment, maintenance of claims, environmental legislation, land use, land claims of local people, water use and mine safety. Failure to comply strictly with applicable laws, regulations and local practices relating to mineral right applications and tenure could result in loss, reduction or expropriation of entitlements, or the imposition of additional local or foreign parties as joint venture partners with carried or other interests. The occurrence of these various factors and uncertainties cannot be accurately predicted and could have an adverse effect on the Company’s operations. In addition, legislation in the United States, Canada or Mexico regulating foreign trade, investment and taxation could have a material adverse effect on the Company’s financial condition. The Sierra Mojada Project is located in Mexico and is subject to varying levels of political, economic, legal and other risks. The Sierra Mojada Project is in Mexico. In the past, Mexico has been subject to political instability, changes and uncertainties that have resulted in changes to existing governmental regulations affecting mineral exploration and mining activities. Mexico’s status as a developing country may make it more difficult for the Company to obtain any required financing for the Sierra Mojada Project or other projects in Mexico in the future. The Sierra Mojada Project is also subject to a variety of governmental regulations governing health and worker safety, employment standards, waste disposal, protection of historic and archaeological sites, mine development, protection of endangered and protected species and other matters. Mexican regulators have broad authority to shut down and/or levy fines against facilities that do not comply with regulations or standards. The Company’s exploration activities in Mexico may be adversely affected to varying degrees by changing government regulations relating to the mining industry or shifts in political conditions that increase the costs related to the Sierra Mojada Project. Changes, if any, in mining or investment policies or shifts in political attitude may adversely affect the Company’s financial condition. Expansion of the Company’s activities will be subject to the need to obtain sufficient access to adequate supplies of water and assure the availability of sufficient power and surface rights that could be affected by government policy and competing operations in the area. The Company also has litigation risk with respect to its operations. See Part I, Item 3 – Legal Proceedings of this Annual Report on Form 10-K for an explanation of material legal proceedings to which Silver Bull or its subsidiaries have been a party. The occurrence of these various factors and uncertainties cannot be accurately predicted and could have an adverse effect on the Company’s financial condition. Future changes in applicable laws and regulations or changes in their enforcement or regulatory interpretation could negatively impact current or planned exploration activities with the Sierra Mojada Project or in respect to any other projects in which the Company becomes involved in Mexico. Any failure to comply with applicable laws and regulations, even if inadvertent, could result in the interruption of exploration operations or material fines, penalties or other liabilities. Title to the Company’s properties may be challenged or defective. The Company’s future operations, including its activities at the Sierra Mojada Project and other exploration activities, will require additional permits from various governmental authorities. The Company’s operations are and will continue to be governed by laws and regulations governing prospecting, mineral exploration, exports, taxes, labor standards, occupational health, waste disposal, toxic substances, land use, environmental protection, mine safety, mining royalties and other matters. There can be no assurance that the Company will be able to acquire all required licenses, permits or property rights on reasonable terms or in a timely manner, or at all, that such terms will not be adversely changed, that required extensions will be granted, or that the issuance of such licenses, permits or property rights will not be challenged by third parties. The Company attempts to confirm the validity of its rights of title to, or contract rights with respect to, each mineral property in which it has a material interest. However, the Company cannot guarantee that title to its properties will not be challenged. The Sierra Mojada Property may be subject to prior unregistered agreements, interests or native land claims, and title may be affected by undetected defects. There may be valid challenges to the title of any of the claims comprising the Sierra Mojada Property that, if successful, could impair possible development and/or operations with respect to such properties in the future. Challenges to permits or property rights (whether successful or unsuccessful), changes to the terms of permits or property rights, or a failure to comply with the terms of any permits or property rights that have been obtained could have a material adverse effect on business by delaying or preventing or making continued operations economically unfeasible. 18 A title defect could result in Silver Bull losing all or a portion of its right, title, and interest to and in the properties to which the title defect relates. Title insurance generally is not available, and the Company’s ability to ensure that it has obtained secure title to individual mineral properties or mining concessions may be severely constrained. In addition, the Company may be unable to operate its properties as permitted or to enforce its rights with respect to its properties. The Company annually monitors the official mining records in Mexico City to determine if there are annotations indicating the existence of a legal challenge against the validity of any of its concessions. As of January 2023, and to the best of the Company’s knowledge, there are no such annotations, nor is the Company aware of any challenges from the government or from third parties, except for the matters described in Part I, Item 3 – Legal Proceedings. In addition, in connection with the purchase of certain mining concessions, Silver Bull agreed to pay a net royalty interest on revenue from future mineral sales on certain concessions at the Sierra Mojada Project, including concessions on which a significant portion of its mineral resources are located. The aggregate amount payable under this royalty is capped at $6.875 million (the “Royalty”), an amount that will only be reached if there is significant future production from the concessions. As noted in Part I, Item 3 (Legal Proceedings), this Royalty is currently the subject of a dispute with a local cooperative. In addition, records from prior management indicate that additional royalty interests may have been created, although the continued applicability and scope of these interests are uncertain. The existence of these royalty interests may have a material effect on the economic feasibility of potential future development of the Sierra Mojada Project. The Company is subject to complex environmental and other regulatory risks, which could expose it to significant liability and delay and potentially the suspension or termination of exploration efforts. The Company’s mineral exploration activities are subject to federal, state and local environmental regulations in the jurisdictions where its mineral properties are located. These regulations mandate, among other things, the maintenance of air and water quality standards and land reclamation. They also set forth limitations on the generation, transportation, storage and disposal of solid and hazardous waste. No assurance can be given that environmental standards imposed by these governments will not be changed, thereby possibly materially adversely affecting the Company’s proposed activities. Compliance with these environmental requirements may also necessitate significant capital outlays or may materially affect the Company’s earning power. Environmental legislation is evolving in a manner that will require stricter standards and enforcement, increased fines and penalties for non-compliance, more stringent environmental assessments of proposed projects, and a heightened degree of responsibility for companies and their officers, directors and employees. As a result of recent changes in environmental laws in Mexico, for example, more legal actions supported or sponsored by non-governmental groups interested in halting projects may be filed against companies operating in all industrial sectors, including the mining sector. Mexican projects are also subject to the environmental agreements entered into by Mexico, the United States and Canada in connection with the United States-Mexico-Canada Agreement. Future changes in environmental regulations in the jurisdictions where the Company’s projects are located may adversely affect its exploration activities, make them prohibitively expensive, or prohibit them altogether. Environmental hazards may exist on the properties in which the Company currently holds interests, such as the Sierra Mojada Project, or may hold interests in the future, that are unknown to it at present and that have been caused by it or previous owners or operators, or that may have occurred naturally. The Company may be liable for remediating any damage that it may have caused. The liability could include costs for removing or remediating the release and damage to natural resources, including ground water, as well as the payment of fines and penalties. The Company’s industry is highly competitive, attractive mineral properties and property concessions are scarce, and it may not be able to obtain quality properties or concessions. The Company competes with other mining and exploration companies in the acquisition of mineral properties and property concessions. There is competition for a limited number of attractive mineral property acquisition opportunities, some of which is with other companies having substantially greater financial resources, staff and facilities than the Company. As a result, the Company may have difficulty acquiring quality mineral properties or property concessions. The Company may face a shortage of water. Water is essential in all phases of the exploration and development of mineral properties. It is used in such processes as exploration, drilling, leaching, placer mining, dredging, testing, and hydraulic mining. Both the lack of available water and the cost of acquisition may make an otherwise viable project economically impossible to complete. In November 2013, Silver Bull was granted the right to exploit up to 3.5 million cubic meters of water per year from six different well sites by the water regulatory body in Mexico, La Comisión Nacional del Agua, but it has yet to be determined if the six well sites can produce this much water over a sustained period of time. 19 The Company’s non-operating properties are subject to various hazards. The Company is subject to risks and hazards, including environmental hazards, possible encounters with unusual or unexpected geological formations, cave-ins, flooding and earthquakes, and periodic interruptions due to inclement or hazardous weather conditions. These occurrences could result in damage to, or the destruction of, mineral properties or future production facilities, personal injury or death, environmental damage, delays in exploration activities, asset write-downs, monetary losses and possible legal liability. The Company may not be insured against all losses or liabilities, either because such insurance is unavailable or because it has elected not to purchase such insurance due to high premium costs or other reasons. Although the Company maintains insurance in an amount that it considers to be adequate, liabilities might exceed policy limits, in which event the Company could incur significant costs that could adversely affect its activities. The realization of any significant liabilities in connection with the Company’s activities as described above could negatively affect its activities and the price of its common stock. RISKS RELATING TO THE COMPANY’S COMMON STOCK: Further equity financings may lead to the dilution of the Company’s common stock. In order to finance future operations, the Company may raise funds through the issuance of common stock or the issuance of debt instruments or other securities convertible into common stock. The Company cannot predict the size of future issuances of common stock or the size and terms of future issuances of debt instruments or other securities convertible into common stock or the effect, if any, that future issuances and sales of the Company’s securities will have on the market price of its common stock. Any transaction involving the issuance of previously authorized but unissued shares, or securities convertible into common stock, would result in dilution, possibly substantial, to present and prospective security holders. Demand for equity securities in the mining industry has been weak; therefore, equity financing may not be available on attractive terms and, if available, will likely result in significant dilution to existing shareholders. No dividends are anticipated. At the present time, the Company does not anticipate paying dividends, cash or otherwise, on its common stock in the foreseeable future. Future dividends will depend on the Company’s earnings, if any, its financial requirements and other factors. There can be no assurance that the Company will pay dividends. The Company’s stock price can be very volatile. The common stock of the Company is listed on the TSX and trades on the OTCQB. The trading price of the Company’s common stock has been, and could continue to be, subject to wide fluctuations in response to announcements of its business developments, results and progress of its exploration activities at the Sierra Mojada Project, progress reports on its exploration activities, and other events or factors. In addition, stock markets have experienced significant price volatility in recent months and years. This volatility has had a substantial effect on the share prices of companies, at times for reasons unrelated to their operating performance. These fluctuations could be in response to: volatility in metal prices; political developments in the foreign countries in which its properties are located; and news reports relating to trends in the industry or general economic conditions. These broad market and industry fluctuations may adversely affect the price of the Company’s common stock, regardless of its operating performance. The Company cannot make any predictions or projections as to what the prevailing market price for its common stock will be at any time, including as to whether its common stock will achieve or remain at levels at or near its offering price, or as to what effect the sale of shares or the availability of common stock for sale at any time will have on the prevailing market price. Item 1B. UNRESOLVED STAFF COMMENTS None. 20 Item 3. LEGAL PROCEEDINGS On May 20, 2014, Mineros Norteños filed an action in the Local First Civil Court in the District of Morelos, State of Chihuahua, Mexico, against the Company’s subsidiary, Minera Metalin, claiming that Minera Metalin breached an agreement regarding the development of the Sierra Mojada Project. Mineros Norteños sought payment of the Royalty, including interest at a rate of 6% per annum since August 30, 2004, even though no revenue has been produced from the applicable mining concessions. It also sought payment of wages to the cooperative’s members since August 30, 2004, even though none of the individuals were hired or performed work for Minera Metalin under this agreement and Minera Metalin did not commit to hiring them. On January 19, 2015, the case was moved to the Third District Court (of federal jurisdiction). On October 4, 2017, the court ruled that Mineros Norteños was time barred from bringing the case. On October 19, 2017, Mineros Norteños appealed this ruling. On July 31, 2019, the Federal Appeals Court upheld the original ruling. This ruling was subsequently challenged by Mineros Norteños and on January 24, 2020, the Federal Circuit Court ruled that the Federal Appeals Court must consider additional factors in its ruling. In March 2020, the Federal Appeals Court upheld the original ruling after considering these additional factors. In August 2020, Mineros Norteños appealed this ruling, which appeal the Company timely responded and objected to on October 5, 2020. On March 26, 2021, the Federal Circuit Court issued a final and conclusive resolution, affirming the Federal Appeals Court decision. Despite the judgments in favour of the Company, Mineros Norteños has continued to block access to the facilities at Sierra Mojada since September 2019. The Company has filed criminal complaints with the State of Coahuila, federal and state authorities have been contacted to intervene and terminate the blockade, and the Company has attempted to negotiate with Mineros Norteños, without resolution to date. The Company has not accrued any amounts in its consolidated financial statements with respect to this claim. On February 15, 2016, Messrs. Jaime Valdez Farias and Maria Asuncion Perez Alonso (collectively, “Valdez”) filed an action before the Local First Civil Court of Torreon, State of Coahuila, Mexico, against the Company’s subsidiary, Minera Metalin, claiming that Minera Metalin had breached an agreement regarding the development of the Sierra Mojada Property. Valdez sought payment in the amount of $5.9 million for the alleged breach of the agreement. On April 28, 2016, Minera Metalin filed its response to the complaint, asserting various defenses, including that Minera Metalin terminated the agreement before the payment obligations arose and that certain conditions precedent to such payment obligations were never satisfied by Valdez. The Company and its Mexican legal counsel asserted all applicable defenses. In May 2017, a final judgment was entered finding for the Company, the defendant, acquitting it of all of the plaintiff’s claims and demands. However, due to a technicality in an early procedural act, Valdez was allowed to, and did, challenge the judgment before a local Appeals Court. On October 1, 2020, the Appeals Court entered a resolution overturning the previous judgment and entering a resolution in favor of Valdez in the amount of $5 million, plus court costs. In November 2020, the judgment of the Appeals Court was timely challenged by the Company by means of an “Amparo” lawsuit (Constitutional protection) before a Federal Circuit Court. In June 2021, the Federal Circuit Court ruled in favor of the plaintiff. In consultation with the Company’s Mexican legal counsel, the Company believes these judgments are contrary to applicable law. No efforts have been made by the plaintiff to enforce the Appeals Court resolution, and in the event such efforts are undertaken, the Company intends to assert a variety of further defenses. The Company believes the likelihood of the plaintiff succeeding in collecting any amount on this claim is remote, as such it has not accrued any amounts in the consolidated financial statements with respect to this claim. See Note 16 – Commitments and Contingencies to the Company’s consolidated financial statements. Item 4. MINE SAFETY DISCLOSURES Not applicable. 21 Item 5.

Item 6. [RESERVED] Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Business Overview Silver Bull, incorporated in Nevada, is an exploration stage company, engaged in the business of mineral exploration. The Company’s primary objective is to define sufficient mineral reserves on the Sierra Mojada Property to justify the development of a mechanized mining operation. Operations in Mexico are conducted through the Company’s wholly-owned Mexican subsidiaries, Minera Metalin and Minas. However, as noted above, Silver Bull has not established any reserves at the Sierra Mojada Property, is in the exploration stage and may never enter the development or production stage. Silver Bull’s corporate office is located at 777 Dunsmuir Street, Suite 1605, Vancouver, British Columbia, Canada V7Y 1G6, telephone number is (604) 687-5800. Recent Developments South32 Option Agreement On June 1, 2018, Silver Bull and its subsidiaries Minera Metalin and Contratistas entered into an earn-in option agreement (the “South32 Option Agreement”) with South32 International Investment Holdings Pty Ltd (“South32”), a wholly owned subsidiary of South32 Limited (ASX/JSE/LSE: S32), whereby South32 was able to obtain an option to purchase 70% of the shares of Minera Metalin and Contratistas (the “South32 Option”). On October 11, 2019, the Company and its subsidiary Minera Metalin issued a notice of force majeure to South32 pursuant to the South32 Option Agreement. Due to a blockade by a cooperative of local miners called Sociedad Cooperativa de Exploración Minera Mineros Norteños, S.C.L. (“Mineros Norteños”), all work was halted on the Sierra Mojada Property. The notice of force majeure was issued because of the blockade’s impact on the ability of the Company and its subsidiary Minera Metalin to perform their obligations under the South32 Option Agreement. Pursuant to the South32 Option Agreement, any time period provided for in the South32 Option Agreement was to be generally extended by a period equal to the period of delay caused by the event of force majeure. On August 31, 2022, the South32 Option Agreement was mutually terminated by South32 and the Company. South32 paid $518,000 to the Company as a final payment for the exploration costs occurred by the Company during the blockade and released South32 from all claims as the date of termination. As of January 26, 2023, the blockade by Mineros Norteños at, on and around the Sierra Mojada Property is ongoing. Goodwill and Possible Other Long-Lived Assets Impairment Goodwill represents the excess, at the date of acquisition, of the purchase price of the business acquired over the fair value of the net tangible and intangible assets acquired. Due to a sustained decrease in the value of the Company’s common stock as a result of the continued blockade at the Sierra Mojada Property, management concluded that this constituted an indication of impairment of goodwill. On April 30, 2022, management performed a qualitative assessment to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount. Based on this assessment, management determined it is more likely than not that the fair value of the reporting unit is less than its carrying amount, and recorded a goodwill impairment of $2,058,031 in the fiscal year ended October 31, 2022. If the blockade at Sierra Mojada Property continues and the Company’s share price remains depressed, then further impairment of other long-lived assets such as property concessions is possible. 23 Sierra Mojada Property In January 2023, the Company’s board of directors approved an exploration budget for the Sierra Mojada Property of $0.3 million and a $0.7 million budget for general and administrative expenses for calendar year 2023. Due to the blockade by Mineros Norteños previously mentioned under the “Recent Developments” section of this Form 10-K, all exploration work remains halted at the Sierra Mojada Property. Until the blockade situation is resolved, the focus of the exploration budget for the Sierra Mojada Property is maintaining the Company’s property concessions. 2022 Drilling During the year ended October 31, 2022, no drilling was conducted as the drilling program remained halted due to the continuing blockade. 2023 Exploration Program The focus of the Company’s 2023 calendar year exploration program at the Sierra Mojada Property will be to resolve the blockade and to maintain property concessions in Mexico. Upon resolution of the blockade, the Company will develop and announce an updated exploration program. Results of Operations Fiscal Year Ended October 31, 2022 Compared to Fiscal Year Ended October 31, 2021 For the fiscal year ended October 31, 2022, the Company reported a consolidated net loss of $3,168,000 or approximately $0.09 per share, compared to a consolidated net loss of $2,448,000 or approximately $0.07 per share during the fiscal year ended October 31, 2021. The $720,000 increase in the consolidated net loss was primarily due to a $1,414,000 increase in exploration and property holding costs (which was mainly the result of the $2,058,000 goodwill impairment as described in the “Recent Developments” section) which was partially offset by a $615,000 decrease in exploration and property costs, a $1,518,000 decrease in general and administrative expense and a $824,000 decrease in other income in the 2022 fiscal year compared to 2021 fiscal year as described below. Exploration and Property Holding Costs Exploration and property holding costs increased by $1,414,000 to $2,392,000 in the 2022 fiscal year from $978,000 in the 2021 fiscal year. This increase was mainly the result of a $2,058,000 goodwill impairment (as described in the “Recent Developments” section) which was partially offset by a $615,000 decrease in exploration and holding costs as the result of costs incurred in connection with the Beskauga Option Agreement in the 2021 fiscal year. There were no comparable expenses in the 2022 fiscal year. General and Administrative Costs General and administrative expenses decreased by $1,518,000 to $1,045,000 in the 2022 fiscal year from $2,563,000 in the 2021 fiscal year as described below. Stock-based compensation was a factor in the fluctuations in general and administrative expenses. Overall stock-based compensation included in general and administrative expense decreased to $296,000 in the 2022 fiscal year from $492,000 in the 2021 fiscal year. This was mainly due to stock options granted to Silver Bull employees, directors and advisors in the 2022 fiscal year compared to Arras stock options granted to Arras’ employees, directors and advisors in the 2021 fiscal year, while Arras was a subsidiary of the Company. Personnel costs decreased by $433,000 to $453,000 in the 2022 fiscal year from $886,000 in the 2021 fiscal year. This decrease was mainly due to a decrease in employees’ salaries in the 2022 fiscal year compared to the 2021 fiscal year included the personnel costs related to Arras. Office and administrative expenses decreased by $146,000 to $235,000 in the 2022 fiscal year from $381,000 in the 2021 fiscal year. This decrease was primarily due to decreased investor relations activities, which in the 2021 fiscal year were incurred in relation to a special meeting of shareholders in December 2020 and the planned distribution of Arras shares to Silver Bull shareholders. Professional services decreased by $685,000 to $183,000 in the 2022 fiscal year from $868,000 in the 2021 fiscal year. This decrease was mainly due to legal and accounting fees incurred in relation to the special meeting of shareholders in December 2020, the incorporation of Arras and the planned distribution of Arras shares in the 2021 fiscal year. 24 Directors’ fees decreased by $208,000 to $158,000 in the 2022 fiscal year as compared to $366,000 for the 2021 fiscal year. This decrease was primarily due to a $137,000 decrease in director fees and decrease in stock-based compensation expense to $86,000 in the 2022 fiscal year from $156,000 in the 2021 fiscal year as a result of stock options vesting in the 2022 fiscal year having a lower fair value than stock options vesting in the 2021 fiscal year. The Company recorded a $14,000 provision for uncollectible VAT for the 2022 fiscal year as compared to a $62,000 provision for uncollectible VAT in the 2021 fiscal year. The allowance for uncollectible taxes in Mexico was estimated by management based upon a number of factors, including the length of time the returns have been outstanding, responses received from tax authorities, general economic conditions in Mexico and estimated net recovery after commissions. Other Income (Expenses) The Company recorded other income of $273,000 in the 2022 fiscal year as compared to other income of $1,097,000 in the 2021 fiscal year. The significant factor contributing to other income in the 2022 fiscal year was a gain of $301,000 from selling Arras common shares and interest income of $6,000, which was offset by a $34,000 foreign currency transaction loss. The significant factor contributing to other income in the 2021 fiscal year was a $1,091,000 unrealized gain of Arras shares held by Silver Bull and $6,000 in foreign currency transaction income. Material Changes in Financial Condition; Liquidity and Capital Resources Disposition of Arras Shares On December 6, 2021, the Company sold 600,000 common shares of Arras at a price of $CDN 1.00 per share for proceeds of $469,484 ($CDN 600,000). On June 15, 2022, the Company sold its remaining 852,262 common shares of Arras at a price of $CDN 1.50 per share for gross proceeds of $994,704 ($CDN 1,278,393), incurring broker costs of $30,075 in relation to the sale. Termination of South32 Option Agreement On August 31, 2022, the South32 Option Agreement was mutually terminated by South32 and the Company. During the 2022 fiscal year, Silver Bull received a payment from South32 in the amount of $518,000 as reimbursement for costs incurred during the force majeure period. Cash Flows During the 2022 fiscal year, cash and cash equivalents were primarily utilized to fund general and administrative expenses and exploration activities at the Sierra Mojada Property. In addition, the Company received $518,000 from South32 and net proceeds of $1,434,000 from the sale of Arras common shares. As a result of the funding from South32 and the proceeds received from the sale of Arras common shares, which were partially offset by exploration activities and general and administrative expenses, cash and cash equivalents increased from $190,000 at October 31, 2021 to $887,000 at October 31, 2022. Cash flows used in operations for the 2022 fiscal year were $1,255,000 as compared to $1,685,000 for the 2021 fiscal year. The decrease was mainly due to due diligence and exploration activities at the Beskauga Property in relation to the Beskauga Option Agreement in the 2021 fiscal year and decreased general and administrative expenses, which were offset by the timing of certain payments. Cash flows provided by investing activities for the 2022 fiscal year were net proceeds of $1,434,000 from the sale Arras common shares. Cash flows used in investing activities for the 2021 fiscal year were $2,516,000, which included $1,928,000 for loans made to Ekidos Minerals LLP, $505,000 cash and cash equivalents that were for the deconsolidation of Arras and $82,000 for the purchase of equipment. Cash flows provided by financing activities for the 2022 fiscal year were $518,000 as compared to $2,531,000 in the 2021 fiscal year. The cash flows provided by financing activities in the 2022 fiscal year were due to funding from South32. The cash flows provided by financing activities in the 2021 fiscal year was due to the 2021 Silver Bull Private Placement, the Arras private placement, the second tranche of 2020 Silver Bull Private Placement , funding from South32 and a Canada Emergency Business Account loan. 25 Capital Resources As of October 31, 2022, the Company had cash and cash equivalents of $887,000 as compared to cash and cash equivalents of $190,000 as of October 31, 2021. The increase in liquidity was primarily the result of the proceeds from the sale of investments and funding from South32, which were partially offset by exploration activities and property holding costs at the Sierra Mojada Property and general and administrative expenses. Since the Company’s inception in November 1993, it has not generated revenue and has incurred an accumulated deficit of $137,394,000. Accordingly, the Company has not generated cash flows from operations, and since inception has relied primarily upon proceeds from private placements and registered direct offerings of its equity securities, warrant exercises, the sale of investments and funding from South32 as the primary sources of financing to fund operations. Based on the limited cash and cash equivalents, and history of losses, there is substantial doubt as to whether the Company’s existing cash resources are sufficient to enable it to continue operations for the next 12 months as a going concern. Management plans to pursue possible financing and strategic options, including, but not limited to, obtaining additional equity financing and the exercise of warrants by warrantholders. However, there is no assurance that the Company will be successful in pursuing these plans. Any future additional financing in the near term will likely be in the form of the issuance of equity securities, which will result in dilution to Silver Bull’s existing shareholders. Moreover, the Company may incur significant fees and expenses in the pursuit of a financing or other strategic transaction, which will increase the rate at which its cash and cash equivalents are depleted. Capital Requirements and Liquidity; Need for Additional Funding The Company’s management and board of directors monitor overall costs, expenses, and financial resources and, if necessary, will adjust planned operational expenditures in an attempt to ensure that the Company has sufficient operating capital. The Company continues to evaluate its costs and planned expenditures, including its Sierra Mojada Property as discussed below. The continued exploration of the Sierra Mojada Property will require significant amounts of additional capital. In January 2023, the board of directors approved an exploration budget for the Sierra Mojada Property of $0.3 million and $0.7 million for general and administrative expenses for calendar year 2023. As of December 31, 2022, the Company had approximately $0.8 million in cash and cash equivalents. The continued exploration of the Sierra Mojada Property ultimately will require the Company to raise additional capital, identify other sources of funding or identify a strategic partner. The Company will continue to evaluate its ability to obtain additional financial resources, and will attempt to reduce or limit expenditures on the Sierra Mojada Property as well as general and administrative costs if it is determined that additional financial resources are unavailable or available on terms that it determines are unacceptable. However, it may not be possible to reduce costs, and even if the Company is successful in reducing costs, it still may not be able to continue operations for the next 12 months as a going concern. If the Company is unable to fund future operations by obtaining additional financial resources or through public or private offerings of equity, it does not expect to have sufficient available cash and cash equivalents to continue its operations for the next 12 months as a going concern. Debt or equity financing may not be available on acceptable terms, if at all. Equity financing, if available, may result in substantial dilution to existing stockholders. If the Company is unable to fund future operations by way of financings, including public or private offerings of equity or debt securities, its business, financial condition and results of operations will be adversely impacted. Off-Balance Sheet Arrangements There are no significant off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on the Company’s financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to its shareholders. Recent Accounting Pronouncements Adopted in the Fiscal Year Ended October 31, 2022 On November 1, 2020, Silver Bull adopted the Financial Accounting Standards Board’s (“FASB’s”) Accounting Standards Updated (“ASU”) 2020-01, “Investments – Equity Securities (Topic 321), Investments – Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) – Clarifying the Interactions between Topic 321, Topic 323, and Topic 815.” This ASU is effective for interim and annual periods beginning after December 15, 2020. The adoption of this update did not have a material impact on the Company’s financial position, results of operations or cash flows and disclosures. 26 Recent Accounting Pronouncements Not Yet Adopted In March 2022, the FASB issued ASU 2022-01, “Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method” which is intended to make amendments to the fair value hedge accounting previously issued in ASU 2017-12 “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities”. The new standard will be effective for reporting periods beginning after December 15, 2022. The standard introduced the portfolio layer method allowing multiple hedged layers of a single closed portfolio when applying fair value hedge accounting. The adoption of this update is not expected to have a material impact on the Company’s financial position, results of operations or cash flows and disclosures. Other recent accounting pronouncements issued by the FASB (including its Emerging Issues Task Force) and the SEC did not or are not expected to have a material impact on the present or future consolidated financial statements of the Company. Critical Accounting Policies and Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires the Company to establish accounting policies and make estimates and assumptions that affect reported amounts of assets and liabilities at the date of the consolidated financial statements. These consolidated financial statements include some estimates and assumptions that are based on informed judgments and estimates of management. The Company evaluates its policies and estimates on an ongoing basis and discuss the development, selection and disclosure of critical accounting policies with the audit committee of the board of directors. Predicting future events is inherently an imprecise activity and as such requires the use of judgment. The Company’s consolidated financial statements may differ based upon different estimates and assumptions. Significant accounting policies are discussed in Note 2, Summary of Significant Accounting Policies, to the consolidated financial statements. The significant accounting policies are subject to judgments and uncertainties that affect the application of such policies. The Company believes that these consolidated financial statements include the most likely outcomes with regard to amounts that are based on management’s judgment and estimates. The consolidated financial position and results of operations may be materially different when reported under different conditions or when using different assumptions in the application of such policies. If estimates or assumptions prove to be different from the actual amounts, adjustments are made in subsequent periods to reflect more current information. The Company believes that the following accounting policies are critical to the preparation of its consolidated financial statements due to the estimation process and business judgment involved in their application: Principles of Consolidation – South32 Option Agreement The Company consolidated entities in which it had a controlling financial interest based on either the variable interest entity (VIE) or voting interest model. Generally, the primary beneficiary of a VIE is a reporting entity that has (a) the power to direct the activities that most significantly impact the VIE’s economic performance, and (b) the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. Currently, the Company managed the mineral exploration program in the property concessions in Mexico through its wholly-owned subsidiary corporations Minera Metalin. The Company determined that Minera Metalin was a variable interest entity and it was the primary beneficiary. Management had applied judgment in reaching its conclusion with respect to accounting for the South32 Option Agreement with South32, described in Note 3 to the consolidated financial statements. Under the South32 Option Agreement, South32 was able to obtain an option to purchase 70% of the shares of Minera Metalin (the “South32 Option”). Management had determined that the South32 Option Agreement did not result in the transfer of control of the Sierra Mojada Project to South32 and that the South32 Option Agreement represented non-employee share-based compensation associated with the collaborative exploration program undertaken by the parties. The compensation cost was expensed when the associated exploration activity occurred. The share-based payments had been classified as equity instruments and valued based on the fair value of consideration received, as it was more reliably measurable than the fair value of the equity interest. In the event the South32 Option was exercised and shares were issued prior to a decision to develop a mine, such shares would have been classified as temporary equity as they would have been contingently redeemable in exchange for a net smelter royalty under circumstances not wholly in control of us or South32 and which were not probable. No portion of the equity value has been classified as temporary equity as the South32 Option has no intrinsic value. Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates based on assumptions about future events that affect the amounts reported in the consolidated financial statements and related notes to the consolidated financial statements. Actual results could differ from those estimates. Estimates and assumptions are reviewed on an ongoing basis based on historical experience and other factors that are considered to be relevant under the circumstances. Revisions to estimates and assumptions are accounted for prospectively. Significant areas involving the use of estimates include determining the allowance for uncollectible taxes, evaluating recoverability of property concessions, evaluating impairment of long-lived assets, evaluating impairment of goodwill, valuation of investments, establishing a valuation allowance on future use of deferred tax assets, calculating a valuation for stock option liability and calculating stock-based compensation. 27 Property Concessions Property concession acquisition costs are capitalized when incurred and will be amortized using the units of production method following the commencement of production. If a property concession is subsequently abandoned or impaired, any capitalized costs will be expensed in the period of abandonment or impairment. To date, no property concessions have reached the production stage. Acquisition costs include cash consideration and the fair market value of shares issued on the acquisition of property concessions. Exploration Costs Exploration costs incurred are expensed to the date of establishing that costs incurred are economically recoverable. Exploration expenditures incurred subsequent to the establishment of economic recoverability are capitalized and included in the carrying amount of the related property. To date, the Company has not established the economic recoverability of its exploration prospects; therefore, all exploration costs are being expensed. Impairment of Long-Lived Assets The Company reviews and evaluates its long-lived assets for impairment when events and changes in circumstances indicate that the related carrying amounts of its assets may not be recoverable. Impairment is considered to exist if the future cash flows on an undiscounted basis are less than the carrying amount of the long-lived asset. An impairment loss is measured and recorded based on the difference between book value and fair value of the asset group. In estimating future cash flows, assets are grouped at the lowest level for which there is identifiable cash flows that are largely independent of cash flows from other asset groups. In estimating future cash flows, the Company estimates the price that would be received to sell an asset group in an orderly transaction between market participants at the measurement date. Significant factors that impact this price include the price of silver and zinc, and general market conditions for exploration companies, among other factors. Goodwill Goodwill is the purchase premium after adjusting for the fair value of net assets acquired. Goodwill is tested for impairment at the reporting unit level at least annually, or more frequently if events or changes in circumstances indicate that the assets may be impaired. Goodwill impairment tests require judgment, including the identification of reporting units, assignment of assets and liabilities to reporting units, assignment of goodwill to reporting units, and determination of the fair value of each reporting unit. Annual goodwill impairment testing is performed on April 30th of each fiscal year. Income Taxes The Tax Cuts and Jobs Act of 2017 was signed into law on December 22, 2017. The law includes significant changes to the U.S. corporate income tax system, including a federal corporate rate reduction from 35% to 21%, limitations on the deductibility of interest expense and executive compensation, and the transition of U.S. international taxation from a worldwide tax system to a territorial tax system. The law did not have a material impact on the Company’s financial position, results of operations or cash flows and disclosures. The asset and liability method of accounting for income taxes is followed. Under this method, deferred income tax assets and liabilities are determined based on temporary differences between the tax basis and accounting basis of the assets and liabilities measured using tax rates enacted at the balance sheet date. The tax benefit from uncertain tax positions is recognized only if it is at least “more likely than not” that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement with the taxing authorities. This accounting standard also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods and disclosure. A valuation allowance is recorded against deferred tax assets if management does not believe that the Company has met the “more likely than not” standard imposed by this guidance to allow recognition of such an asset. Management recorded a full valuation allowance at October 31, 2022 and October 31, 2021 against the deferred tax assets as it determined that future realization would not meet the “more likely than not” criteria. 28 Stock-Based Compensation The Black-Scholes pricing model is used as a method for determining the estimated fair value for all stock options awarded to employees, officers, directors and consultants. The expected term of the options is based upon an evaluation of historical and expected future exercise behavior. The risk-free interest rate is based on rates published by the government for bonds with a maturity similar to the expected remaining life of the options at the valuation date. Volatility is determined based upon historical volatility of the Company’s stock and adjusted if future volatility is expected to vary from historical experience. The dividend yield is assumed to be none as Silver Bull has not paid dividends nor does it anticipate paying any dividends in the foreseeable future. The graded vesting attribution method is used to recognize compensation costs over the requisite service period. Cumulative compensation cost associated with options on subsidiary equity are classified as additional paid-in capital until exercised. Foreign Currency Translation During the fiscal years ended October 31, 2022 and October 31, 2021, the functional currency of Silver Bull Resources, Inc. and its subsidiaries was the U.S. dollar. During the fiscal years ended October 31, 2022 and October 31, 2021, Silver Bull’s Mexican operations’ monetary assets and liabilities with foreign source currencies were translated into U.S. dollars at the period-end exchange rate, and non-monetary assets and liabilities with foreign source currencies were translated using the historical exchange rate. The Mexican operations’ revenue and expenses were translated at the average exchange rate during the period except for depreciation of office and mining equipment, costs of office and mining equipment sold and impairment of property concessions, all of which are translated using the historical exchange rate. Foreign currency translation gains and losses of the Mexican operations are included in the consolidated statements of operations. Accounting for Loss Contingencies and Legal Costs From time to time, the Company is named as a defendant in legal actions arising from its normal business activities. An accrual for the estimated loss from a loss contingency is recorded when information available prior to issuance of the financial statements indicates that it is probable that a liability has been incurred at the date of the financial statements and the amount of the loss can be reasonably estimated. Disclosure of a loss contingency is made by the Company if there is at least a reasonable possibility that a loss has been incurred, and either an accrual has not been made or an exposure to loss exists in excess of the amount accrued. In cases where only disclosure of the loss contingency is required, either the estimated loss or a range of estimated loss is disclosed or it is stated that an estimate cannot be made. Legal costs incurred in connection with loss contingencies are considered period costs and accordingly are expensed in the period services are provided. Investments Investments comprise an approximately nil and 3% interest in Arras at October 31, 2022 and 2021, respectively. Investments are measured at fair value through profit or loss, with gains or losses from changes in fair value recognized in the consolidated statements of operations and comprehensive loss. Item 7A.

CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE None. 29 Item 9A. CONTROLS AND PROCEDURES (a) Evaluation of Disclosure Controls and Procedures As of October 31, 2022, the Company has carried out an evaluation under the supervision of, and with the participation of its Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of its disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act). Based on the evaluation as of October 31, 2022 , the Company’s Chief Executive Officer and Chief Financial Officer have concluded that its disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) were effective. Disclosure controls and procedures are designed to ensure that information required to be disclosed in the Company’s reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in its reports filed under the Exchange Act is accumulated and communicated to management, including the Company’s principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. (b) Management’s Report on Internal Control over Financial Reporting Management is responsible for establishing and maintaining adequate internal control over financial reporting, as that term is defined in Rule 13a-15(f) under the Exchange Act. Under the supervision and with the participation of the Company’s management, including its principal executive and principal financial officers, the Company assessed, as of October 31, 2022, the effectiveness of its internal control over financial reporting. This assessment was based on criteria established in the Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on the Company’s assessment using those criteria, management concluded that its internal control over financial reporting as of October 31, 2022 was effective. Internal control over financial reporting is defined as a process designed by, or under the supervision of, the Company’s principal executive and principal financial officers and effected by its board of directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles, and includes those policies and procedures that: pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the Company’s assets; provide reasonable assurance that transactions are recorded as necessary to permit the preparation of financial statements in accordance with U.S. generally accepted accounting principles and that receipts and expenditures are being made only in accordance with authorizations of management and directors; and provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of assets that could have a material effect on the financial statements. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the internal control system are met. Because of the inherent limitations of any internal control system, no evaluation of controls can provide absolute assurance that all control issues, if any, within a company have been detected. (c) Changes in Internal Controls over Financial Reporting There were no changes in the Company’s internal control over financial reporting during the fiscal year ended October 31, 2022 that materially affected, or were reasonably likely to materially affect, its internal control over financial reporting.

(an exploration stage company) (the “Company”) as of October 31, 2022 and 2021, and the related consolidated statements of operations and comprehensive loss, cash flows, and stockholders’ equity for the years then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of October 31, 2022 and 2021, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America. Going Concern Uncertainty The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has suffered recurring losses from operations and has limited cash and cash equivalents at October 31, 2022. These circumstances raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Basis for Opinion These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion. F-2 Critical Audit Matters Critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing a separate opinion on the critical audit matters or on the accounts or disclosures to which they relate. We have determined that there are no critical audit matters to communicate in our auditors’ report. /s/ Smythe LLP Smythe LLP, Chartered Professional Accountants We have served as the Company’s auditor since 2016.

F-9 NOTE 1 – ORGANIZATION AND DESCRIPTION OF BUSINESS Silver Bull Resources, Inc. (the “Company”) was incorporated in the State of Nevada on November 8, 1993 as the Cadgie Company for the purpose of acquiring and developing mineral properties. The Cadgie Company was a spin-off from its predecessor, Precious Metal Mines, Inc. On June 28, 1996, the Company’s name was changed to Metalline Mining Company. On April 21, 2011, the Company’s name was changed to Silver Bull Resources, Inc. The Company’s fiscal year-end is October 31. The Company has not realized any revenues from its planned operations and is considered an exploration stage company. The Company has not established any reserves with respect to its exploration projects and may never enter into the development stage with respect to any of its projects. The Company engages in the business of mineral exploration. The Company currently owns a number of property concessions in Mexico (collectively known as the “Sierra Mojada Property”). The Company conducts its operations in Mexico through its wholly-owned subsidiary corporations, Minera Metalin S.A. de C.V. (“Minera Metalin”), Contratistas de Sierra Mojada S.A. de C.V. (“Contratistas”) and Minas de Coahuila SBR S.A. de C.V. (“Minas”). On August 26, 2021, Contratistas merged with and into Minera Metalin. On April 16, 2010, Metalline Mining Delaware, Inc., a wholly-owned subsidiary of the Company incorporated in the State of Delaware, was merged with and into Dome Ventures Corporation (“Dome”), a Delaware corporation. As a result, Dome became a wholly-owned subsidiary of the Company. Dome has a wholly-owned subsidiary Dome Asia Inc. (“Dome Asia”), which is incorporated in the British Virgin Islands. On August 12, 2020, the Company entered into an option agreement (the “Beskauga Option Agreement”) with Copperbelt AG, a corporation existing under the laws of Switzerland (“Copperbelt Parent”), and Dostyk LLP, an entity existing under the laws of Kazakhstan and a wholly-owned subsidiary of Copperbelt (the “Copperbelt Sub,” and together with Copperbelt Parent, “Copperbelt”), pursuant to which the Company has the exclusive right and option (the “Beskauga Option”) to acquire Copperbelt’s right, title and 100% interest in the Beskauga property located in Kazakhstan (the “Beskauga Property”), which consists of the Beskauga Main project (the “Beskauga Main Project”) and the Beskauga South project (the “Beskauga South Project,” and together the Beskauga Main Project, the “Beskauga Project”). After the completion of due diligence, the transaction contemplated by the Beskauga Option Agreement closed on January 26, 2021. On February 5, 2021, Arras Minerals Corp. (“Arras”) was incorporated in British Columbia, Canada, as a wholly-owned subsidiary of the Company. On March 19, 2021, pursuant to an asset purchase agreement with Arras, the Company transferred its right, title and interest in and to the Beskauga Option Agreement, among other things, to Arras in exchange for 36,000,000 common shares of Arras. On September 24, 2021, the Company distributed to its shareholders one Arras common share for each Silver Bull share held by such shareholders, or 34,547,838 Arras shares in total. Upon completion of the distribution, the Company retained 1,452,162 Arras common shares, or approximately 4% of the outstanding Arras common shares, as a strategic investment (Note 5), and Arras became a stand-alone company. The Company has included the financial results of Arras in its consolidated statement of operations for the period from February 5, 2021 to September 24, 2021, the date of the distribution. The Company’s efforts and expenditures have been concentrated on the exploration of properties, principally in the Sierra Mojada Property located in Coahuila, Mexico. The Company has not determined whether its exploration properties contain ore reserves that are economically recoverable. The ultimate realization of the Company’s investment in exploration properties is dependent upon the success of future property sales, the existence of economically recoverable reserves, and the ability of the Company to obtain financing or make other arrangements for exploration, development, and future profitable production activities. The ultimate realization of the Company’s investment in exploration properties cannot be determined at this time. Going Concern Since its inception in November 1993, the Company has not generated revenue and has incurred an accumulated deficit of $137,394,000. Accordingly, the Company has not generated cash flows from operations, and since inception the Company has relied primarily upon proceeds from private placements and registered direct offerings of the Company’s equity securities and warrant exercises as the primary sources of financing to fund the Company’s operations. As of October 31, 2022, the Company had cash and cash equivalents of $887,000. Based on the Company’s limited cash and cash equivalents, and history of losses, there is substantial doubt as to whether the Company’s existing cash resources are sufficient to enable the Company to continue its operations for the next 12 months as a going concern. Management plans to pursue possible financing and strategic options including, but not limited to, obtaining additional equity financing. Management has successfully pursued these options previously and believes that they alleviate the substantial doubt that the Company can continue its operations for the next 12 months as a going concern. However, there is no assurance that the Company will be successful in pursuing these plans. These consolidated financial statements have been prepared on a going concern basis and do not include any adjustments to the amounts and classification of assets and liabilities that may be necessary in the event the Company can no longer continue as a going concern. Such adjustments could be material. F-10 NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES This summary of significant accounting policies is presented to assist in understanding the consolidated financial statements. The consolidated financial statements and notes are representations of the Company’s management, which is responsible for their integrity and objectivity. Basis of Presentation The Company’s consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) using the accrual method of accounting, except for cash flow amounts. All figures are in United States dollars unless otherwise noted. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries, after elimination of intercompany accounts and transactions. The wholly owned subsidiaries of the Company are listed in Note 1 to the consolidated financial statements. The Company consolidated entities in which it has a controlling financial interest based on either the variable interest entity (VIE) or voting interest model. Under the VIE model, a VIE is a reporting entity that has (a) the power to direct the activities that most significantly impact the VIE’s economic performance, and (b) the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. Currently, the Company manages the mineral exploration program in the property concessions in Mexico through its wholly-owned subsidiary corporation Minera Metalin. Use of Estimates The preparation of these consolidated financial statements in conformity with GAAP requires management to make estimates based on assumptions about future events that affect the amounts reported in the consolidated financial statements and related notes to the consolidated financial statements. Actual results could differ from those estimates. Estimates and assumptions are reviewed on an ongoing basis based on historical experience and other factors that are considered to be relevant under the circumstances. Revisions to estimates and assumptions are accounted for prospectively. Significant areas involving the use of estimates include determining the allowance for uncollectible taxes, evaluating recoverability of property concessions, evaluating impairment of long-lived assets, evaluating impairment of goodwill, valuation of investments, establishing a valuation allowance on future use of deferred tax assets, calculating a valuation for stock option liability and calculating stock-based compensation. Cash and Cash Equivalents Cash and cash equivalents include all highly-liquid investments with an original maturity of three months or less at the date of purchase. Property Concessions Property concession acquisition costs are capitalized when incurred and will be amortized using the units of production method following the commencement of production. If a property concession is subsequently abandoned or impaired, any capitalized costs will be expensed in the period of abandonment or impairment. To date, no property concessions have reached the production stage. Acquisition costs include cash consideration and the fair market value of shares issued on the acquisition of property concessions. Exploration Costs Exploration costs incurred are expensed to the date of establishing that costs incurred are economically recoverable. Exploration expenditures incurred subsequent to the establishment of economic recoverability are capitalized and included in the carrying amount of the related property. To date, the Company has not established the economic recoverability of its exploration prospects; therefore, all exploration costs are being expensed. F-11 Office and Mining Equipment Property and equipment are recorded at cost less accumulated depreciation and impairment losses. Assets under construction are depreciated when they are substantially complete and available for their intended use, over their estimated useful lives. Repairs and maintenance of property and equipment are expensed as incurred. Costs incurred to enhance the service potential of property and equipment are capitalized and depreciated over the remaining useful life of the improved asset. Property and equipment are depreciated using the straight-line method over the estimated useful lives of the related assets as follows: ● Mining equipment – five to 10 years ● Vehicles – four years ● Building and structures – 40 years ● Computer equipment and software – three years ● Well equipment – 10 to 40 years ● Office equipment – three to 10 years Impairment of Long-Lived Assets Management reviews and evaluates its long-lived assets for impairment when events and changes in circumstances indicate that the related carrying amounts of its assets may not be recoverable. Impairment is considered to exist if the future cash flows on an undiscounted basis are less than the carrying amount of the long-lived asset. An impairment loss is measured and recorded based on the difference between book value and fair value of the asset group. In estimating future cash flows, assets are grouped at the lowest level for which there is identifiable cash flows that are largely independent of cash flows from other asset groups. In estimating future cash flows, the Company estimates the price that would be received to sell an asset group in an orderly transaction between market participants at the measurement date. Significant factors that impact this price include the price of silver and zinc, and general market conditions for exploration companies, among other factors. Goodwill Goodwill is the purchase premium after adjusting for the fair value of net assets acquired. The Company tests goodwill for impairment at the reporting unit level at least annually, or more frequently if events or changes in circumstances indicate that the assets may be impaired. Goodwill impairment tests require judgment, including the identification of reporting units, assignment of assets and liabilities to reporting units, assignment of goodwill to reporting units, and determination of the fair value of each reporting unit. The Company performs its annual goodwill impairment tests on April 30th of each fiscal year. Based on this assessment, management determined it is more likely than not that the fair value of the reporting unit is less than its carrying amount, and recorded a goodwill impairment of $2,058,031 during the year ended October 31, 2022. Income Taxes The Company follows the asset and liability method of accounting for income taxes. Under this method, deferred income tax assets and liabilities are determined based on temporary differences between the tax basis and accounting basis of the assets and liabilities measured using tax rates enacted at the balance sheet date. The Company recognizes the tax benefit from uncertain tax positions only if it is at least “more likely than not” that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement with the taxing authorities. This accounting standard also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods and disclosure. A valuation allowance is recorded against deferred tax assets if management does not believe that the Company has met the “more likely than not” standard imposed by this guidance to allow recognition of such an asset. Management recorded a full valuation allowance at October 31, 2022 and 2021 against the deferred tax assets as it determined that future realization would not meet the “more likely than not” criteria. F-12 Stock-Based Compensation The Company uses the Black-Scholes pricing model as a method for determining the estimated fair value for all stock options awarded to employees, officers, directors and consultants. The expected term of the options is based upon an evaluation of historical and expected future exercise behavior. The risk-free interest rate is based on rates published by the government for bonds with a maturity similar to the expected remaining life of the options at the valuation date. Volatility is determined based upon historical volatility of the Company’s stock and adjusted if future volatility is expected to vary from historical experience. The dividend yield is assumed to be none as the Company has not paid dividends nor does the Company anticipate paying any dividends in the foreseeable future. The Company uses the graded vesting attribution method to recognize compensation costs over the requisite service period. The Company classifies cumulative compensation cost associated with options on subsidiary equity as additional paid-in capital until exercise. Loss per Share Basic loss per share includes no dilution and is computed by dividing net loss available to common shareholders by the weighted average common shares outstanding for the period. Diluted loss per share reflects the potential dilution of securities that could share in the earnings of an entity similar to fully diluted loss per share. Although there were stock options and warrants in the aggregate of 5,165,039 shares and 2,015,039 shares outstanding at October 31, 2022 and 2021, respectively, they were not included in the calculation of loss per share because they would have been considered anti-dilutive. Foreign Currency Translation During the years ended October 31, 2022 and 2021, the functional currency of Silver Bull Resources, Inc. and its subsidiaries was the U.S. dollar. During the years ended October 31, 2022 and 2021, the Company’s Mexican operations’ monetary assets and liabilities with foreign source currencies were translated into U.S. dollars at the period-end exchange rate and non-monetary assets and liabilities with foreign source currencies were translated using the historical exchange rate. The Company’s Mexican operations’ revenue and expenses were translated at the average exchange rate during the period except for depreciation of office and mining equipment, costs of office and mining equipment sold and impairment of property concessions, all of which are translated using the historical exchange rate. Foreign currency translation gains and losses of the Company’s Mexican operations are included in the consolidated statement of operations. Accounting for Loss Contingencies and Legal Costs From time to time, the Company is named as a defendant in legal actions arising from its normal business activities. The Company records an accrual for the estimated loss from a loss contingency when information available prior to issuance of its financial statements indicates that it is probable that a liability has been incurred at the date of the financial statements and the amount of the loss can be reasonably estimated. Disclosure of a loss contingency is made by the Company if there is at least a reasonable possibility that a loss has been incurred, and either an accrual has not been made or an exposure to loss exists in excess of the amount accrued. In cases where only disclosure of the loss contingency is required, either the estimated loss or a range of estimated loss is disclosed or it is stated that an estimate cannot be made. Legal costs incurred in connection with loss contingencies are considered period costs and accordingly are expensed in the period services are provided. Investments Investments comprise an approximately nil and 3% interest in Arras at October 31, 2022 and 2021, respectively. The Company’s investments are measured at fair value through profit or loss, with gains or losses from changes in fair value recognized in the consolidated statements of operations and comprehensive loss. F-13 Recent Accounting Pronouncements Adopted in the Year On November 1, 2021, the Company adopted the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Updated (“ASU”) 2019-12, “Income Taxes - Simplifying the Accounting for Income Taxes (Topic 740)” which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and clarifies and amends existing guidance to improve consistent application. ASU 2019-12 will be effective for interim and annual periods beginning after December 15, 2020. Early adoption is permitted. The adoption of this update did not have a material impact on the Company’s financial position, results of operations or cash flows and disclosures. Recent Accounting Pronouncements Not Yet Adopted In March 2022, the FASB issued ASU 2022-01, “Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method” which is intended to make amendments to the fair value hedge accounting previously issued in ASU 2017-12 “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities”. The new standard will be effective for reporting periods beginning after December 15, 2022. The standard introduced the portfolio layer method allowing multiple hedged layers of a single closed portfolio when applying fair value hedge accounting. The adoption of this update is not expected to have a material impact on the Company’s financial position, results of operations or cash flows and disclosures. Other recent accounting pronouncements issued by the FASB (including its Emerging Issues Task Force) and the SEC did not or are not expected to have a material impact on the Company’s present or future consolidated financial statements. NOTE 3 – SOUTH32 OPTION AGREEMENT On June 1, 2018, the Company and its subsidiaries Minera Metalin and Contratistas entered into an earn-in option agreement (the “South32 Option Agreement”) with South32 International Investment Holdings Pty Ltd (“South32”), a wholly-owned subsidiary of South32 Limited (ASX/JSE/LSE: S32), whereby South32 was able to obtain an option to purchase 70% of the shares of Minera Metalin and Contratistas (the “South32 Option”). On October 11, 2019, the Company and its subsidiary Minera Metalin issued a notice of force majeure to South32 pursuant to the South32 Option Agreement. Due to a blockade by a cooperative of local miners called Sociedad Cooperativa de Exploración Minera Mineros Norteños, S.C.L. (“Mineros Norteños”), all work was halted on the Sierra Mojada Property. The notice of force majeure was issued because of the blockade’s impact on the ability of the Company and its subsidiary Minera Metalin to perform their obligations under the South32 Option Agreement. Pursuant to the South32 Option Agreement, any time period provided for in the South32 Option Agreement was to be generally extended by a period equal to the period of delay caused by the event of force majeure. On August 31, 2022, the South32 Option Agreement was mutually terminated by South32 and the Company. No portion of the equity value has been classified as temporary equity as the South32 Option has no intrinsic value. Minera Metalin owns the Sierra Mojada Property located in Coahuila, Mexico (the “Sierra Mojada Project”) and supplies labor for the Sierra Mojada Project. Under the South32 Option Agreement, South32 could have earned into the South32 Option by funding a collaborative exploration program on the Sierra Mojada Project. Upon the terms and subject to the conditions set forth in the South32 Option Agreement, in order for South32 to earn and maintain its four-year option, South32 was to have contributed to Minera Metalin for exploration of the Sierra Mojada Project at least $3 million by the end of Year 1, $6 million by the end of Year 2, $8 million by the end of Year 3 and $10 million by the end of Year 4 (the “Initial Funding”). Funding was made on a quarterly basis based on the subsequent quarter’s exploration budget. South32 was able to exercise the South32 Option by contributing $100 million to Minera Metalin (the “Subscription Payment”), less the amount of Initial Funding previously contributed by South32. The issuance of shares upon notice of exercise of the South32 Option by South32 was subject to antitrust approval by the Mexican government. If the full amount of the Subscription Payment had been advanced by South32 and the South32 Option became exercisable and was exercised, the Company and South32 would have been obligated to contribute funding to Minera Metalin on a 30/70 pro rata basis. If South32 elected not to continue with the South32 Option during the four-year option period, the Sierra Mojada Project would remain 100% owned by the Company. The exploration program was initially managed by the Company, with South32 being able to approve the exploration program funded by it. The Company received funding of $3,144,163 from South32 for Year 1 of the South32 Option Agreement. In April 2019, the Company received a notice from South32 to maintain the South32 Option Agreement for Year 2 by providing cumulative funding of $6 million by the end of such period. The Company received funding of $1,502,831, which included payments of $319,430, $1,100,731 and $82,670 received during the years ended October 31, 2019, 2020 and 2021, respectively, from South32 for Year 2 of the South32 Option Agreement, the time period for which was extended by the event of force majeure as described above. During the year ended October 31, 2022, the Company received a payment from South32 in the amount of $518,000 as reimbursement for costs incurred during the force majeure period. As of October 31, 2022, the Company had received cumulative funding of $5,164,994 under the South32 Option Agreement. If the South32 Option Agreement was terminated by South32 without cause or if South32 was unable to obtain antitrust authorization from the Mexican government, the Company would be under no obligation to reimburse South32 for amounts contributed under the South32 Option Agreement. Upon exercise of the South32 Option, Minera Metalin would have been required to issue common shares to South32. Pursuant to the South32 Option Agreement, following exercise and until a decision has been made by the board of directors of Minera Metalin to develop and construct a mine on the Sierra Mojada Project, each shareholder holding greater than or equal to 10% of the shares may withdraw as an owner in exchange for a 2% net smelter royalty on products produced and sold from the Sierra Mojada Project. Any shareholder whose holdings are reduced to less than 10% must surrender its interest in exchange for a 2% net smelter royalty. F-14 The Company determined that Minera Metalin is a variable interest entity and that the South32 Option Agreement did not result in the transfer of control of the Sierra Mojada Project to South32. The Company also determined that the South32 Option Agreement represented non-employee share-based compensation associated with the collaborative exploration program undertaken by the parties. The compensation cost is expensed when the associated exploration activity occurs. The share-based payments have been classified as equity instruments and valued based on the fair value of the cash consideration received, as it is more reliably measurable than the fair value of the equity interest. If the South32 Option had been exercised and shares were issued prior to a decision to develop a mine, such shares would have been classified as temporary equity as they would have been contingently redeemable in exchange for a net smelter royalty under circumstances that were not wholly in control of the Company or South32 and were not probable. As of January 26, 2023, the blockade by Mineros Norteños at, on and around the Sierra Mojada Property is ongoing. South32 paid $518,000 to the Company as a final payment for the exploration costs occurred by the Company during the blockade and released South32 from all claims as the date of termination. NOTE 4 – DUE FROM RELATED PARTY As of October 31, 2022, due from related party consists of $23,196 due from Arras for shared employees’ salaries and office expenses. This amount is non-interest bearing and to be repaid on demand. NOTE 5 – VALUE-ADDED TAX RECEIVABLE Value-added tax (“VAT”) receivable relates to VAT paid in Mexico. The Company estimates net VAT of $127,036 (2021 - $120,810) will be received and believes that it remains legally entitled to be refunded the full amount of the VAT receivable and intends to rigorously continue its VAT recovery efforts, this being supported by the Company’s July 2022 receipt of its claim for the month of October 2017 in the full amount of $4,363 filed, with back interest and inflation adjustment amounts additionally being received (total of Mexican Peso (“$MXN”) 179,837). While the Company continues to pursue recovery from the Mexican government, the Company reclassified the carrying value of the receivable to non-current assets as of October 31, 2022 based on the continued failure to recover the VAT receivable and a recent preliminary unfavorable ruling from the Mexican tax authority, which the Company is in the process of challenging. The allowance for uncollectible VAT was estimated by management based upon a number of factors, including the length of time the returns have been outstanding, responses received from tax authorities, general economic conditions in Mexico and estimated net recovery after commissions. A summary of the changes in the allowance for uncollectible VAT for the fiscal years ended October 31, 2022 and 2021 is as follows: Allowance for uncollectible VAT – October 31, 2020 Provision for uncollectible VAT Foreign currency translation adjustment Allowance for uncollectible VAT – October 31, 2021 Provision for uncollectible VAT Foreign currency translation adjustment Allowance for uncollectible VAT – October 31, 2022 NOTE 6 – INVESTMENTS $ $ 345,059 62,024 13,899 420,982 14,113 14,124 449,219 On August 12, 2020, the Company entered into the Beskauga Option Agreement with Copperbelt pursuant to which it had the exclusive right and option to acquire Copperbelt’s right, title and 100% interest in the Beskauga property located in Kazakhstan. On March 19, 2021, the Company transferred its interest in the Beskauga Option Agreement to its subsidiary, Arras. On September 24, 2021, pursuant to a Separation and Distribution Agreement, the Company distributed to its shareholders one Arras common share for each Silver Bull share held by such shareholders, or 34,547,838 Arras common shares in total (the “Distribution”). Upon completion of the Distribution, the Company retained 1,452,162 Arras shares, or approximately 4% of the outstanding Arras common shares, as a strategic investment. At the time of the Distribution, the Company determined that Arras was no longer a controlled subsidiary due to the dilution of its interest in Arras and the fact that Arras became a stand-alone company at the time of the Distribution. On the date control was lost, the Company recorded its interest retained in Arras at carrying value without gain or loss. F-15 The net assets of Arras as at September 24, 2021, the date of disposition, was as follows: Cash and cash equivalents Other receivables Loan receivable Property concessions Office and mining equipment, net Accounts payable Accrued liabilities and expenses Net assets – September 24, 2021 $ $ 505,228 13,319 2,288,500 327,690 108,534 (547,405) (553,428) 2,142,438 The Company determined that the Company’s retained interest in Arras is accounted for using the fair value method for the period from September 24, 2021, onwards, and its investments in Arras is presented as an investment. On October 21, 2021, Arras completed a private placement. The Company did not participate in this private placement. As a result of the Arras common share issuance, the Company’s interest in Arras decreased to approximately 3% as of October 31, 2021. On December 6, 2021, the Company sold 600,000 common shares of Arras at a price of $CDN 1.00 per share for proceeds of $469,484 ($CDN 600,000). On June 15, 2022, the Company sold the remaining 852,262 common shares of Arras at a price of $CDN 1.50 per share for gross proceeds of $994,704 ($CDN 1,278,393) and incurred broker costs of $30,075 in relation to the sale. A summary of the changes in investments for the years ended October 31, 2022 and 2021 is as follows: Equity security – October 31, 2020 Carrying value of investment on deconsolidation Gain on investment Equity security – October 31, 2021 Sale of investment, net of costs Gain on investment Foreign currency translation adjustment Equity security – October 31, 2022 Non-Controlling Interest $ $ $ — 75,817 1,090,953 1,166,770 (1,434,113) 301,493 (34,150) — On April 1, 2021, Arras completed an initial private placement (the “Arras Private Placement”) for 5,035,000 common shares at a purchase price of $CDN 0.50 per share for gross proceeds of $2,000.319 ($CDN 2,517,500). No placement agent or finder’s fees were paid in connection with the Arras Private Placement. Arras incurred other offering costs associated with the Arras Private Placement of $20,687. The Arras Private Placement was considered a change in the ownership interest of a subsidiary that the Company controls and accordingly, the Company accounted for this as an equity transaction. The Company has correspondingly recorded a non-controlling interest for the portion of Arras not owned by the Company. As a result of the transaction, the Company maintains a controlling interest of 88% of Arras issued and outstanding common shares. Mainly due to this impact, the Company recorded a non-controlling interest for the dilution gain from changes in interest in subsidiary of $1,979,633. There were no changes in the number of Arras common shares held by the Company. On September 24, 2021, upon completion of the Distribution, the Company retained 1,452,162 Arras common shares, or approximately 4% of the outstanding Arras common shares, as a strategic investment, and Arras became a stand-alone company. The Company ceased consolidating the consolidated financial statements of Arras effective September 24, 2021, as the Company determined that it no longer exercised control over Arras. Accordingly, the Company’s retained interest in Arras is accounted for using the fair value method. On September 24, 2021, the Company derecognized the net assets of Arras, and the non-controlling interest related to Arras. As of October 31, 2021, the Company held approximately 3% of the outstanding Arras shares, reduced from the distribution date due to Arras completing an equity financing. F-16 The carrying value of the non-controlling interest at October 31, 2021 was as follows: Non-controlling interests – October 31, 2020 Changes in interests in subsidiary – April 1, 2021 Loss for the period Distribution of interest in Arras Non-controlling interests – October 31, 2021 NOTE 7 – OFFICE AND MINING EQUIPMENT The following is a summary of the Company’s office and mining equipment at October 31, 2022 and 2021: Mining equipment Vehicles Buildings and structures Computer equipment and software Well equipment Office equipment Less: Accumulated depreciation Office and mining equipment, net NOTE 8 – PROPERTY CONCESSIONS $ $ — 1,979,633 (198,138) (1,781,495) — October 31, 2022 October 31, 2021 396,153 $ 92,873 185,724 74,236 39,637 47,597 836,220 (692,652) 143,568 $ 396,153 92,873 185,724 74,236 39,637 47,597 836,220 (672,080) 164,140 $ $ The following is a summary of the Company’s property concessions in Sierra Mojada, Mexico as at October 31, 2022 and 2021: Property Concessions – October 31, 2022 and 2021 $ 5,019,927 NOTE 9 – GOODWILL Goodwill represents the excess, at the date of acquisition, of the purchase price of the business acquired over the fair value of the net tangible and intangible assets acquired. The Company’s inability to advance the Sierra Mojada Project due to the ongoing blockade has resulted in a sustained decrease in the value of the Company’s common stock. As such, the Company concluded that this constituted an indication of impairment of goodwill. On April 30, 2022, the Company elected to perform a qualitative assessment to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying amount. Based on this assessment, management determined it is more likely than not that the fair value of the reporting unit is less than its carrying amount, and as such, the Company recorded a goodwill impairment of $2,058,031 during the year ended October 31, 2022. The following is a summary of the Company’s goodwill balance as at October 31, 2022 and 2021: Goodwill – October 31, 2021 Impairment Goodwill – October 31, 2022 NOTE 10 – LOAN PAYABLE $ $ 2,058,031 (2,058,031) — In June 2020, the Company received $29,531 ($CDN 40,000) in the form of a Canada Emergency Business Account (“CEBA”) loan. CEBA is part of the economic assistance program launched by the Government of Canada to ensure that businesses have access to capital during the COVID-19 pandemic that can only be used to pay non-deferrable operating expenses. During the period from receipt of the CEBA loan to December 31, 2022 (the “Initial Term”), no interest will be charged on the principal amount outstanding. If at least $CDN 30,000 is repaid on or before the end of the Initial Term, the remaining $CDN 10,000 of principal will be forgiven pursuant to the terms of the CEBA loan. During the period from January 1, 2023 to December 31, 2025 (the “Extended Term”), if any portion of the loan remains outstanding, interest will be payable monthly at a rate of 5% per annum on the outstanding principal balance. F-17 In January 2021, the Company applied and qualified for an additional $15,615 ($CDN 20,000) CEBA loan. Fifty percent (50%) of the additional loan is forgivable if repaid by December 31, 2022. The loan accrues no interest before the end of the Initial Term, and thereafter converts to a three-year term loan with a 5% annual interest rate. Any portion of the loan is repayable without penalty at any time prior to December 31, 2025. The total CEBA loan amount stands at $CDN 60,000 with $CDN 20,000 forgivable if repaid by December 31, 2022. In January 2022, the repayment deadline for CEBA loan to qualify for loan forgiveness had been extended to December 31, 2023. The balance of the CEBA loan is fully repayable on or before the end of the Extended Term, if not repaid on or before the end of the Initial Term. The Company anticipates repaying the CEBA loan upon or before the completion of the Initial Term. An income will be recognized in the period when the CEBA loan is forgiven. Loan payable – October 31, 2020 Loan payable received – January 2021 Foreign currency translation adjustment Loan payable – October 31, 2021 Foreign currency translation adjustment Loan payable – October 31, 2022 NOTE 11 – COMMON STOCK $ $ 30,034 15,615 2,801 48,450 (4,491) 43,959 On February 17, 2022, the Company issued 507,814 shares of common stock at an average of $0.25 per share of common stock as payment of accrued management bonuses in the amount of $128,094 ($CDN162,500) based on the closing trading price on the date of Board’s approval. Following shareholder approval, the Company amended its articles of incorporation on April 20, 2021 to, among other things, increase the number of authorized shares of common stock from 37,500,000 to 150,000,000. On September 9, 2021, options to acquire 1,078,125 shares of common stock were exercised on a cashless basis, whereby the recipients elected to receive 220,471 shares without payment of the cash exercise price, and the remaining options for 857,654 shares were cancelled. On June 25, 2021, the Company completed a private placement (the “2021 Silver Bull Private Placement”) for 500,000 shares of common stock for gross proceeds of $405,351 ($CDN 500,000). No placement agent or finder’s fees were paid in connection with the 2021 Silver Bull Private Placement. The Company incurred other offering costs associated with the 2021 Silver Bull Private Placement of $14,628. On June 15, 2021, options to acquire 375,000 shares of common stock were exercised on a cashless basis, whereby the recipient elected to receive 113,436 shares without payment of the cash exercise price, and the remaining options for 261,564 shares were cancelled.

On November 9, 2020, the Company completed the second and final tranche of a private placement (the “2020 Silver Bull Private Placement”) for 319,000 units (each, a “Unit”) at a purchase price of $0.47 per Unit for gross proceeds of $149,930. Each Unit consists of one share of the Company’s common stock and one half of one transferable common stock purchase warrant (each whole warrant, a “Warrant”). Each Warrant entitles the holder thereof to acquire one share of common stock and one common share of Arras as per the terms of the Separation and Distribution agreement between Silver Bull and Arras completed in conjunction with the Distribution, at a price of $0.59 until November 9, 2025. The Company incurred other offering costs associated with the second and final tranche of the 2020 Silver Bull Private Placement of $6,780. Subscribers of the second and final tranche of the 2020 Silver Bull Private Placement included management for a total 319,000 Units and gross proceeds of $149,930. F-18 NOTE 12 – STOCK OPTIONS The Company has one stock option plan under which equity securities are authorized for issuance to officers, directors, employees and advisors: the 2019 Stock Option and Stock Bonus Plan (the “2019 Plan”). The 2019 Plan was amended on April 19, 2022 (the “Amended 2019 Plan”). Under the Amended 2019 Plan, 10% of the total shares outstanding are reserved for issuance upon the exercise of options or the grant of stock bonuses, to a maximum of 15,000,000 shares. Options are typically granted with an exercise price equal to the closing market price of the Company’s stock at the date of grant, have a graded vesting schedule over two or three years and have a contractual term of five years. A summary of the range of assumptions used to value stock options granted for the years ended October 31, 2022 and 2021 are as follows: Options Expected volatility Risk-free interest rate Dividend yield Expected term (in years) Year Ended October 31, 2022 2021 81% – 87% 1.60% – 1.74% — 2.50 – 5.00 — — — — On February 17, 2022, the Company granted options to acquire 3,300,000 shares of common stock with a weighted-average grant-date fair value of $0.14 per share and an exercise price of $CDN 0.32 per share. No options were exercised during the year ended October 31, 2022. No options were granted during the year ended October 31, 2021. On September 9, 2021, options to acquire 1,078,125 shares of common stock were exercised on a cashless basis at an average exercise price of $CDN 1.03 per share. 220,471 shares of common stock were issued and 857,654 options were cancelled.

As of October 31, 2022, there remains $130,311 of total unrecognized compensation expense, which is expected to be recognized over a weighted average period of 0.53 years. During the year ended October 31, 2021, while a subsidiary of the Company, Arras granted options to acquire 5,060,000 common shares with a weighted-average grant-date fair value of $0.22 per share and an exercise price of $CDN 0.50 per share. The Company recognized stock-based compensation costs for the Arras stock options of $587,505 for the period from inception on February 5, 2021 to September 24, 2021. F-19 The Company and Arras applied the fair value method using the Black-Scholes option pricing model in accounting for their stock options granted. Accordingly, share-based compensation of $223,895 was recognized as personnel costs for options granted to employees, share-based compensation of $72,356 was recognized as directors’ fees for options granted to directors and share-based compensation of $9,528 was recognized as exploration and property holding costs for options granted to employees and advisors.

The Company files a United States federal income tax return and a Canadian branch return on a fiscal year-end basis and files Mexican income tax returns for its two Mexican subsidiaries on a calendar year-end basis. The Company and two of its wholly-owned subsidiaries, Minera Metalin and Minas, have not generated taxable income since inception. Contratistas, another wholly-owned Mexican subsidiary, has historically generated taxable income based upon intercompany fees billed to Minera Metalin on the services it provides. On August 26, 2021, Contratistas merged with and into Minera Metalin. On April 16, 2010, a wholly-owned subsidiary of the Company was merged with and into Dome, resulting in Dome becoming a wholly-owned subsidiary of the Company. Dome, a Delaware corporation, files a tax return in the United States as part of the Company’s consolidated tax return. The components of loss before income taxes were as follows: United States Foreign Loss before income taxes The components of the provision for income taxes are as follows: Current tax expense Deferred tax expense For the year ended October 31, 2022 2021 (766,000) $ (2,398,000) (3,164,000) $ 13,000 (2,456,000) (2,443,000) For the year ended October 31, 2022 2021 4,520 $ — 4,520 $ 4,550 — 4,550 $ $ $ $ The Company’s provision for income taxes for the fiscal year ended October 31, 2022 consisted of a tax expense of $4,520 (2021 - $4,550) related to a provision for income taxes for the Silver Bull Canadian branch return for the fiscal year ended October 31, 2022. F-21 The reconciliation of the provision for income taxes computed at the U.S. statutory rate to the provision for income tax as shown in the statement of operations and comprehensive loss is as follows: Income tax benefit calculated at U.S. federal income tax rate $ (665,000) $ (514,000) For the year ended October 31, 2022 2021 Differences arising from: Other permanent differences Differences due to foreign income tax rates Adjustment to prior year taxes Inflation adjustment foreign net operating loss Foreign currency fluctuations Decrease in valuation allowance Net operating loss carry forwards deconsolidation - Canada Net operating loss carry forwards expiration - Mexico Net income tax provision The components of the deferred tax assets at October 31, 2022 and 2021 were as follows: Deferred tax assets: Net operating loss carry forwards – U.S. Net operating loss carry forwards – Mexico Exploration costs Other – United States Other – Mexico Total net deferred tax assets Less: valuation allowance Net deferred tax asset 524,000 (29,000) 447,000 (797,000) (51,000) (1,840,000) — 2,416,000 5,000 $ 2,766,000 (129,000) 56,000 (323,000) (227,000) (2,551,000) 93,000 834,000 5,000 For the year ended October 31, 2022 2021 5,235,000 $ 3,711,000 961,000 68,000 44,000 10,019,000 (10,019,000) — $ 5,035,000 5,922,000 814,000 46,000 42,000 11,859,000 (11,859,000) — $ $ $ At October 31, 2022, the Company has U.S. net operating loss carry-forwards of approximately $20 million that expire in the years 2028 through 2037 and $5 million which will be carried forward indefinitely. The Company has approximately $16 million of net operating loss carry-forwards in Mexico that expire in the calendar years 2022 through 2031. The valuation allowance for deferred tax assets of $10.0 and $11.9 million at October 31, 2022 and 2021, respectively, relates principally to the uncertainty of the utilization of certain deferred tax assets, primarily net operating loss carry forwards in various tax jurisdictions. The Company continually assesses both positive and negative evidence to determine whether it is more likely than not that the deferred tax assets can be realized prior to their expiration. Based on the Company’s assessment, it has determined that the deferred tax assets are not currently realizable. F-22 Net Operating Loss Carry Forward Limitation For U.S. federal income tax purposes, a change in ownership under IRC Section 382 has occurred as a result of the Dome merger in April 2010. When an ownership change has occurred, the utilization of these losses against future income would be subject to an annual limitation, which would be equal to the value of the acquired company immediately prior to the change in ownership multiplied by the IRC Section 382 rate in effect during the month of the change. Accounting for Uncertainty in Income Taxes During the fiscal years ended October 31, 2022 and 2021, the Company has not identified any unrecognized tax benefits or had any additions or reductions in tax positions and therefore a reconciliation of the beginning and ending amount of unrecognized tax benefits is not presented. The Company does not have any unrecognized tax benefits as of October 31, 2022, and accordingly the Company’s effective tax rate will not be materially affected by unrecognized tax benefits. The following tax years remain open to examination by the Company’s principal tax jurisdictions: United States: Mexico: Canada: 2018 and all following years 2017 and all following years 2018 and all following years The Company has not identified any uncertain tax position for which it is reasonably possible that the total amount of unrecognized tax benefit will significantly increase or decrease within the next 12 months. The Company’s policy is to classify tax related interest and penalties as income tax expense. There is no interest or penalties estimated on the underpayment of income taxes as a result of unrecognized tax benefits. NOTE 15 – FINANCIAL INSTRUMENTS Fair Value Measurements All financial assets and financial liabilities are recorded at fair value on initial recognition. Transaction costs are expensed when they are incurred, unless they are directly attributable to the acquisition of financial assets or the assumption of liabilities carried at amortized cost, in which case the transaction costs adjust the carrying amount. The three levels of the fair value hierarchy are as follows: Level 1 Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2 Level 3 Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity). Under fair value accounting, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s financial instruments consist of cash and cash equivalents, due from related party, investments, accounts payable and loan payable. Cash and cash equivalents, due from related party and accounts payable are classified as level 1 in the fair value hierarchy. Their carry amounts approximate fair value at October 31, 2022 and 2021 due to the short maturities of these financial instruments. Investments and loan payable are classified as level 2 in the fair value hierarchy. Credit Risk Credit risk is the risk that the counterparty to a financial instrument will cause a financial loss for the Company by failing to discharge its obligations. To mitigate exposure to credit risk on financial assets, the Company has established policies to ensure liquidity of funds and ensure that counterparties demonstrate minimum acceptable credit worthiness. F-23 The Company maintains its U.S. dollar and $CDN cash and cash equivalents in bank and demand deposit accounts with major financial institutions with high credit standings. Cash deposits held in Canada are insured by the Canada Deposit Insurance Corporation (“CDIC”) for up to $CDN 100,000. Certain Canadian bank accounts held by the Company exceed these federally insured limits or are uninsured as they related to U.S. dollar deposits held in Canadian financial institutions. As of October 31, 2022 and 2021, the Company’s cash and cash equivalent balances held in Canadian financial institutions included $802,761 and $98,617, respectively, which was not insured by the CDIC. The Company has not experienced any losses on such accounts and management believes that using major financial institutions with high credit ratings mitigates the credit risk in cash and cash equivalents. The Company also maintains cash in bank accounts in Mexico. These accounts are denominated in the local currency and are considered uninsured. As of October 31, 2022 and 2021, the U.S. dollar equivalent balance for these accounts was $10,702 and $10,239, respectively. Interest Rate Risk The Company holds substantially all of the Company’s cash and cash equivalents in bank and demand deposit accounts with major financial institutions. The interest rates received on these balances may fluctuate with changes in economic conditions. Based on the average cash and cash equivalent balances during the fiscal year ended October 31, 2022, a 1% decrease in interest rates would have resulted in a reduction in interest income for the period of approximately $529. Foreign Currency Exchange Risk Certain purchases of labor, operating supplies and capital assets are denominated in $CDN, $MXN or other currencies. As a result, currency exchange fluctuations may impact the costs of the Company’s operations. Specifically, the appreciation of the $MXN or $CDN against the U.S. dollar may result in an increase in operating expenses and capital costs in U.S. dollar terms. The Company currently does not engage in any currency hedging activities. Based on the net exposures as at October 31, 2022, a 5% depreciation or appreciation of the $CDN and $MXN against the US dollar would result in an increase/decrease of approximately $9,000 in the Company’s net income. Liquidity Risk Liquidity risk is the risk that the Company will be unable to meet its financial obligations as they fall due. The Company’s approach to managing its liquidity risk is to ensure, as far as possible, that it will have sufficient liquid funds to meet its liabilities when due. At October 31, 2022, the Company has $886,728 (2021 - $189,607) of cash and cash equivalents to settle current liabilities of $342,192 (2021 - $791,319). All payables classified as current liabilities are due within one year. NOTE 16 – COMMITMENTS AND CONTINGENCIES Compliance with Environmental Regulations The Company’s exploration activities are subject to laws and regulations controlling not only the exploration and mining of mineral properties, but also the effect of such activities on the environment. Compliance with such laws and regulations may necessitate additional capital outlays or affect the economics of a project, and cause changes or delays in the Company’s activities. Property Concessions Mexico To properly maintain property concessions in Mexico, the Company is required to pay a semi-annual fee to the Mexican government and complete annual assessment work. Royalty The Company has agreed to pay a 2% net smelter return royalty on certain property concessions within the Sierra Mojada Property based on the revenue generated from production. Total payments under this royalty are limited to $6.875 million (the “Royalty”). To date, no royalties have been paid. F-24 Litigation and Claims Mineros Norteños Case On May 20, 2014, Mineros Norteños filed an action in the Local First Civil Court in the District of Morelos, State of Chihuahua, Mexico, against the Company’s subsidiary, Minera Metalin, claiming that Minera Metalin breached an agreement regarding the development of the Sierra Mojada Property. Mineros Norteños sought payment of the Royalty, including interest at a rate of 6% per annum since August 30, 2004, even though no revenue has been produced from the applicable mining concessions. It also sought payment of wages to the cooperative’s members since August 30, 2004, even though none of the individuals were hired or performed work for Minera Metalin under this agreement and Minera Metalin did not commit to hiring them. On January 19, 2015, the case was moved to the Third District Court (of federal jurisdiction). On October 4, 2017, the court ruled that Mineros Norteños was time barred from bringing the case. On October 19, 2017, Mineros Norteños appealed this ruling. On July 31, 2019, the Federal Appeals Court upheld the original ruling. This ruling was subsequently challenged by Mineros Norteños and on January 24, 2020, the Federal Circuit Court ruled that the Federal Appeals Court must consider additional factors in its ruling. In March 2020, the Federal Appeals Court upheld the original ruling after considering these additional factors. In August 2020, Mineros Norteños appealed this ruling, which appeal the Company timely responded and objected to on October 5, 2020. On March 26, 2021, the Federal Circuit Court issued a final and conclusive resolution, affirming the Federal Appeals Court decision. Despite the judgments in favour of the Company, Mineros Norteños has continued to block access to the facilities at Sierra Mojada since September 2019. The Company has filed criminal complaints with the State of Coahuila, federal and state authorities have been contacted to intervene and terminate the blockade, and the Company has attempted to negotiate with Mineros Norteños, without resolution to date. The Company has not accrued any amounts in its consolidated financial statements with respect to this claim. Valdez Case On February 15, 2016, Messrs. Jaime Valdez Farias and Maria Asuncion Perez Alonso (collectively, “Valdez”) filed an action before the Local First Civil Court of Torreon, State of Coahuila, Mexico, against the Company’s subsidiary, Minera Metalin, claiming that Minera Metalin had breached an agreement regarding the development of the Sierra Mojada Property. Valdez sought payment in the amount of $5.9 million for the alleged breach of the agreement. On April 28, 2016, Minera Metalin filed its response to the complaint, asserting various defenses, including that Minera Metalin terminated the agreement before the payment obligations arose and that certain conditions precedent to such payment obligations were never satisfied by Valdez. The Company and the Company’s Mexican legal counsel asserted all applicable defenses. In May 2017, a final judgment was entered finding for the Company, the defendant, acquitting the Company of all of the plaintiff’s claims and demands. However, due to a technicality in an early procedural act, Valdez was allowed to, and did, challenge the judgment before a local Appeals Court. On October 1, 2020, the Appeals Court entered a resolution overturning the previous judgment and entering a resolution in favor of Valdez in the amount of $5 million, plus court costs. In November 2020, the judgment of the Appeals Court was timely challenged by the Company by means of an “Amparo” lawsuit (Constitutional protection) before a Federal Circuit Court. In June 2021, the Federal Circuit Court ruled in favour of the plaintiff. The Company believes these judgments are contrary to applicable law. The plaintiff initiated proceedings to enforce the Appeals Court resolution, and the Company has offered a mining concession as a payment in full to terminate this controversy definitively. The Company believes the likelihood of the plaintiff succeeding in collecting any amount on this claim is remote, as such the Company has not accrued any amounts in its consolidated financial statements with respect to this claim. From time to time, the Company is involved in other disputes, claims, proceedings and legal actions arising in the ordinary course of business. The Company intends to vigorously defend all claims against the Company, and pursue its full legal rights in cases where the Company has been harmed. Although the ultimate outcome of these proceedings cannot be accurately predicted due to the inherent uncertainty of litigation, in the opinion of management, based upon current information, no other currently pending or overtly threatened proceeding is expected to have a material adverse effect on the Company’s business, financial condition or results of operations. COVID-19 Global outbreaks of contagious diseases, including the December 2019 outbreak of a strain of coronavirus (COVID-19), have the potential to significantly and adversely impact the Company’s operations and business. On March 11, 2020, the World Health Organization recognized COVID-19 as a global pandemic. Pandemics or disease outbreaks such as the COVID-19 outbreak may have a variety of adverse effects on the Company’s business, including by depressing commodity prices and the market value of its securities and limiting the ability of management to meet with potential financing sources. The spread of COVID-19 has had, and continues to have, a negative impact on the financial markets, which may impact the Company’s ability to obtain additional financing in the near term. A prolonged downturn in the financial markets could have an adverse effect on the Company’s business, results of operations and ability to raise capital.

(“AC”) and Mr. Timothy Barry for Silver Bull Resources Inc. (“Silver Bull” or “SBR”), in accordance with subpart 1300 of Regulaon S-K (“S-K 1300”) promulgated under the Securies Act of 1933, as amended, for the updated mineral resources at the Sierra Mojada Project in Coahuila state, Mexico. This Technical Report replaces the technical report for the mineral resources at the Sierra Mojada Project in Coahuila state, Mexico, dated October 30, 2018, prepared in accordance with NI-43-101 by Mr. Mahew Dumala of AC and Mr. Timothy Barry of Silver Bull. This Technical Report is inclusive of both the near surface silver mineralizaon that has been referred to as the “Shallow Silver Zone” (SSZ) and the historic “red” and “white” zinc zones that had been historically mined by underground methods. Since the previous report, significant work has been done on structural and geologic mapping, modeling of the deposit and follow-up on previous work recommendaons. The Sierra Mojada Project has been the subject of previous NI43-101 technical reports which disclosed mineral resource esmates for the Shallow Silver Zone and the Red Zinc Zone respecvely: · · · · · · · Archer Cathro Ltd. & Silver Bull Resources Inc. report, dated October 2018 Tuun and AFK Mining resource report, dated May 2015 JDS Preliminary Economic Assessment (PEA) in December 2013 JDS resource report in April 2013 SRK in July 2012 and November 2011 John Nilsson (and Ronald Simpson) in April 2011 Pincock Allen & Holt (PAH) in January 2010. 1.2 PROPERTY DESCRIPTION The Sierra Mojada project is located in the northwestern part of Coahuila State, Mexico, close to the border with Chihuahua State. The project centre coordinates are 27°24’ North and longitude 103°43’ West. The project is adjacent to the towns of Esmeralda and Sierra Mojada and is about 250 km northeast of the city of Torreón. The project has excellent paved highway and rail access. 11 Silver Bull has 20 registered mining concessions for a total area of 9,530.4 hectares. Silver Bull operates in Mexico through a wholly owned Mexican subsidiary, Minera Metalin S.A. de C.V. All minerals in Mexico are owned by the federal government and mineral rights are granted by solicing mining concessions, which by law have priority over surface land use, but in pracce the concessions owner must have an agreement with the surface owner. 1.3 ACCESSIBILITY, CLIMATE, LOCAL RESOURCES, INFRASTRUCTURE AND PHYSIOGRAPHY The Sierra Mojada project area is situated in the northwestern part of Coahuila State, Mexico at latude, close to the border with Chihuahua State, south of the village of Esmeralda. It is accessible by paved roads from the city of Torreón, which lies about 250 km to the southwest. Most of the area adjacent to the project site is used for low yield cale ranching, however; the southeastern boundary of the project abuts the Peñoles dolomite extracon and processing facility. The Peñoles quarrying facility contains associated waste piles and a 1 km long conveyor belt transporng crushed dolomic carbonate aggregate of specific magnesium carbonate grade to the railroad spur for transportaon to the Peñoles process plant known locally as Quimica del Rey. A rail line ulized by Peñoles to transport material to its chemical plant extends west to La Esmeralda. The remains of an older secon extend right up to old workings and a loading facility located south of La Mesa Blanca right in the center of the Sierra Mojada Camp. The spur line connects the main naonal line that connects Escalon and Monclova. Rail traffic to the east is through Frontera to the United States via Eagle Pass, Texas, or southward to Monterrey or the seaport at Altamira. Service to the west is available as well as to the western USA via El Paso, or to points south connected through Torreón. Although power levels are sufficient for current operaons and exploraon, any development of the project would potenally require addional power supplies to be sourced. 1.4 HISTORY The Sierra Mojada project area is host to several mineralized zones varying from the ‘red zinc’ (hemimorphite-rich) manto; a ‘white zinc’ (smithsonite-rich) manto; and silver-lead rich zones. As reported in the AC and SVB October 2018 resource report: 12 “Silver and lead were first discovered by a foraging party in 1879, and mining to 1886 consisted of nave silver, silver chloride, and lead carbonate ores. Aer 1886, silver-lead-zinc-copper sulphate ores within limestone and sandstone units were produced. No accurate producon history has been found for historical mining during this period.” “Approximately 120 years ago, zinc silicate and zinc carbonate minerals (Zinc Manto Zone) were discovered underlying the silver-lead mineralized horizon. The zinc manto is predominantly zinc dominated, but with subordinate lead–rich manto and is principally situated in the footwall rocks of the Sierra Mojada Fault System. Since discovery and up to 1990; zinc, silver, and lead ores were mined from various mines along the strike of the deposit, including from the Sierra Mojada property. Ores mined from within these areas were hand sorted and the concentrate shipped mostly to smelters in the United States.” Metalline Mining Company (Metalline) entered into a Joint Exploraon and Development Agreement with USMX in July 1996, involving USMX’s Sierra Mojada concessions. In October 1999, Metalline entered into a joint venture with North Limited of Melbourne, Australia (now Rio Tinto). Exploraon by North Limited consisted of underground channel samples in addion to surface RC and diamond drilling. North Limited withdrew from the joint venture in October 2000. A joint venture agreement was made with Peñoles in November 2001. The agreement allowed Peñoles to acquire 60% of the project by compleng a bankable Feasibility Study and making annual payments to Metalline. During 2002, Peñoles conducted an underground exploraon program consisng of driving raises through the oxide zinc manto, diamond drilling, connuaon of the percussion drilling and channel sampling of the oxide zinc workings (stopes and dris) previously started by Metalline in 1999, and connued by North in 2000 and Metalline during 2001. In December 2003, the joint venture was terminated by mutual consent between Peñoles and Metalline. Since 2003, Metalline connued sampling numerous underground workings through channel and grab samples. In April 2010, Metalline merged with Dome Ventures, retaining the name Metalline Mining Inc. Subsequently, in April 2011, the company changed its name to Silver Bull Resources. Silver Bull connued to diamond drill the project unl February of 2013.” 13 In June 2018, Silver Bull signed a Joint Venture opon with South32 Limited to form a 70/30 joint venture on the Sierra Mojada Project. To maintain the opon in good standing, South32 must contribute minimum exploraon funding of US$10 million ("Inial Funding") during a 4 year opon period with minimum aggregate exploraon funding of US$3 million, US$6 million and US$8 million to be made by the end of years 1, 2 and 3 of the opon period respecvely. South32 may exercise its opon to subscribe for 70% of the shares of Minera Metalin S.A. De C.V. ("Metalin"), the wholly owned subsidiary of Silver Bull which holds the claims in respect of the Project, by contribung $US100 million to Metalin for Project funding, less the amount of the Inial Funding contributed by South32 during the opon period. The opon with South32 was terminated in September 2022 due to an ongoing blockade of the project. 1.5 GEOLOGY AND MINERALIZATION Sierra Mojada is located in the Eastern Tectonic Zone of Mexico, which represents a passive plate margin relave to the Western Zone that abuts a convergent plate margin. The boundary between the Eastern and Western terrains is in Chihuahua State, just west of the Sierra Mojada project area. Within the Eastern Zone, the project is located in the Coahuila terrain, which consists of moderately metamorphosed flysch and un- metamorphosed andesic volcanic rocks cut by granite and granodiorite intrusives of Permian to Triassic age. The district is located on passive margin type Cretaceous plaorm carbonate rocks of the Sabinas Basin, which have been structurally prepared from Jurassic through Terary me by the complex San Marcos fault system. Along the San Marcos fault system are one or more mineralizing intrusions that are inferred from direct and indirect evidence in the district leading to the idenficaon of the district as being a CRD (Carbonate Replacement Deposit). The district shows a complex history of hypogene sulphide mineralizaon followed by oxidaon and supergene alteraon of the mineral profile. Hydrothermal alteraon follows a clear sequence of dolomizaon, carbonate and silica alteraon; followed by late carbonate, silica, argillic, and iron oxide alteraons related to the oxidaon- supergene events. Approximately 80% of the district mineralizaon is hosted by dolomite; the remainder is in limestone. The alteraon-mineralizing events have generated two types of mineralizaon in the Sierra Mojada district. The Shallow Silver Zone (SSZ) and the Base Metal Manto Zone (BMM). Mineralizaon in the Shallow Silver Zone is dominated by acanthite, the silver halide solid soluon of bromargyritechlorargyrite, and tennante. Silver occurs in early to late high-grade structures, karst breccias, low angle fault breccias, and mantos, and as disseminated replacements in porous hydrothermally altered dolomites. 14 The Base Metal mineralizaon is dominated by hemimorphite in the Red Zinc Zone and smithsonite in the White Zinc Zone. Mineralizaon primarily occurs as replacement of karst breccia and accessory faults that feed the breccia zones. Non-sulphide base metal mineralizaon is a result of oxidaon and supergene enrichment of an original zone of semi-to massive pyrite-sphalerite-galena mineralizaon largely located in the lead zone manto mineralizaon. The result is a silver-rich polymetallic zone of mineralizaon overlaying a large non-sulphide zinc-lead-copper resource, both forming a linear zone of manto shaped mineralizaon which is cross cut by mineralized structures. 1.6 EXPLORATION STATUS Since the Archer Cathro and SVB October 2018 resource report, work has focused on sulphide mineralizaon that lies outside the resource defined by the 2015 Report. A joint venture opon was signed with South32 Ltd. in June 2018 to explore the sulphide potenal of the property at depth. The sulphide mineralizaon is thought to be of the same genesis as the oxide mineralizaon and is simply the “unoxidized” version of the mineralizaon originally emplaced at Sierra Mojada. However, because a different metallurgical process would almost certainly be required to beneficiate the sulphide mineralizaon, the new zone of sulphide mineralizaon recently idenfied at Sierra Mojada is not included in the resource outlined in this report. 1.7 SAMPLE PREPARATION, ANALYSES, SECURITY AND DATA VERIFICATION During the me Mr. Barry has worked on the Sierra Mojada Project there has been no change in the methodology of sample preparaon and chain-of-custody. In 2010, the onsite assay lab was decommissioned to eliminate any quesons of sampling bias. As noted in Tuun and AFK May 2015 resource report: “All analycal work used in the project has been performed in the ALS laboratory (“ALS”) in Vancouver, BC, Canada. ALS is a leading independent provider of assaying and analycal tesng services for mining and exploraon companies. The laboratory is ISO 9001:2000 and ISO/IEC 1702S:2005 cerfied. SRK is of the opinion that the sample preparaon, security and analysis meets or exceeds industry standards and is adequate to support a mineral resource esmate as defined under NI 43- 101, but that beer care should be taken in reviewing and analyzing the QA/QC. 15 SRK downloaded all available data from ALS and compared the digital database supplied by Silver Bull against original assay data provided by ALS. A total of 37,100 assays were checked against the digital database, which represents about 23% of the total assay populaon. While some discrepancies were observed, most of the errors were considered not material and most were easily explained. A few samples that did not agree with the assay cerficates were not used for the resource esmate.” Mr. Barry has been direct e-mail copied of results from ALS-Chemex (now ALS-Global) with the assays and has had the opportunity to verify the assays against the loaded data. In addion, in 2011 IoGlobal Pty Ltd (based in Australia) provided data verificaon services to Silver Bull Resources. For the B series 2012 holes and the T-series 2012 holes used for twinning of old holes and underground exploraon. The Qualified Person considers the database fit-for-purpose and is suitable for use in the esmaon of Mineral Resources and was collected in line with industry best pracce. 1.8 METALLURGICAL TESTING Metallurgical tesng of the mineralizaon at Sierra Mojada in the early years of Metalline Mining Co. work focused on the oxidized zinc mineralizaon. Poor recoveries and low metal prices persuaded Silver Bull to consider other technologies. The SART Process and its applicaon to Sierra Mojada Project mineralizaon was also examined. Improved recoveries and the ability to recover/reduce cyanide consumpon suggest improved economics that need to be further evaluated. 1.9 MINERAL RESOURCES Classificaon has been done adhering to S-K 1300 Standards. A 10 m by 10 m by 10 m block model was created to encompass the deposit, grades were esmated into the block model in three passes using Ordinary Kriging (OK). Silver, copper, lead and zinc were esmated using uncapped composited 1.0m grades. 16 1.9.1 MINERAL RESOURCE Mineral Resources are sub-divided, in order of increasing geological confidence, into Inferred, Indicated and Measured categories. An Inferred Mineral Resource has a lower level of confidence than that applied to an Indicated Mineral Resource. An Indicated Mineral Resource has a higher level of confidence than an Inferred Mineral Resource but has a lower level of confidence than a Measured Mineral Resource. A Mineral Resource is a concentraon or occurrence of diamonds, natural solid inorganic material, or natural solid fossilized organic material including base and precious metals, coal, and industrial minerals in or on the Earth’s crust in such form and quanty and of such a grade or quality that it has reasonable prospects for economic extracon. The locaon, quanty, grade, geological characteriscs and connuity of a Mineral Resource are known, esmated or interpreted from specific geological evidence and knowledge. The term Mineral Resource covers mineralizaon and natural material of intrinsic economic interest which has been idenfied and esmated through exploraon and sampling and within which Mineral Reserves may subsequently be defined by the consideraon and applicaon of technical, economic, legal, environmental, socio-economic and governmental factors. The phrase ‘reasonable prospects for economic extracon’ implies a judgement by the Qualified Person in respect of the technical and economic factors likely to influence the prospect of economic extracon. A Mineral Resource is an inventory of mineralizaon that under realiscally assumed and jusfiable technical and economic condions might become economically extractable. These assumpons must be presented explicitly in both public and technical reports. 1.9.2 MINERAL RESOURCE ESTIMATE The silver and zinc resource at Sierra Mojada has been classified as “Measured”, “Indicated” and “Inferred” and has been confined within an opmize While pit shell to demonstrate reasonable prospects of economic extracon. The pit shell was generated using a silver price of US$18 per ounce and a zinc price of US$1.20 per pound. Metal prices were chosen to reflect five year averages. Mining costs (ore and waste) of US$1.50/tonne, processing costs of US$12.00/tonne (including G&A) to provide an overall NSR cutoff grade of $13.50 for the Global in-pit resource. An overall pit slope of 55° was used for the pit opmizaons. Recoveries were assumed to be 75% for the silver and 41% for the zinc. Although reported, no value was assigned to the copper or lead. Historic mining voids were removed from the resource esmate. One small mineral license not under the control of Silver Bull is included within the open pit. The resource contained within this license is not reported. 17 The “Global Resource” is shown in Table 1 Table 1.

Grades are rounded to the nearest decimal place for Ag, Zn, & Pb and the nearest 2 decimal places for Cu 1.9.3 ZINC AND SILVER ZONES WITHIN THE GLOBAL RESOURCE The Global Resource encompasses two high grade zones of mineralizaon; locally named the zinc zone, and the silver zone and represents an overall average grade for the silver and zinc mineralizaon across the enre deposit. This average grade does not accurately reflect discrete, high grade zoning of the silver and zinc mineralizaon that occurs within the global resource and which are beer defined using zinc and silver cutoff grades. The “sub” tables using a silver and zinc cutoff grade are shown below: 18 Table 2. “Zinc Zone” Pit-constrained Mineral Resource Esmate by Zinc Cut-Off Category Zn Cut-off (%) Tonnes (Mt) Ag (g/t) Cu (%) Pb (%) Zn (%) Ag Cu Pb Zn (Mozs) (Mlbs) (MLbs) (Mlbs) MEASURED INDICATED TOTAL M&I INFERRED 4 6 8 10 11 12 13 14 4 6 8 10 11 12 13 14 6 4 6 8 17.1 11.9 8.6 6.2 5.1 4.3 3.6 2.9 2.5 1.6 0.8 0.4 0.3 0.2 0.2 0.2 13.5 0.05 0.04 0.03 26.9 22.3 19.3 15.8 14.5 13.8 12.9 11.7 22.2 20.4 18.7 19.2 19.5 19.6 19.8 21.9 22.0 5.9 6.5 5.7 0.4% 0.4% 0.4% 0.3% 0.3% 0.3% 0.3% 0.2% 0.3% 0.3% 0.3% 0.3% 0.3% 0.3% 0.3% 0.3% 0.4% 0.2% 0.2% 0.2% 0.02% 0.02% 0.02% 0.02% 0.02% 0.02% 0.02% 0.02% 0.03% 0.03% 0.02% 0.02% 0.02% 0.02% 0.02% 0.02% 0.02% 0.01% 0.01% 0.01% 19 9.5% 14.8 11.5% 13.3% 15.0% 15.8% 16.7% 17.5% 18.5% 7.7% 9.2% 11.4% 13.7% 15.0% 15.9% 16.4% 16.9% 11.2% 8.5% 9.6% 11.0% 8.5 5.3 3.1 2.4 1.9 1.5 1.1 1.8 1.0 0.5 0.2 0.2 0.2 0.1 0.1 9.6 0.01 0.01 0.00 8.6 4.7 2.9 2.1 1.7 1.4 1.2 1.0 1.5 0.9 0.3 0.2 0.1 0.1 0.1 0.1 5.6 0.01 0.01 0.01 162.3 106.4 69.9 43.6 34.0 27.6 21.2 15.3 17.6 11.1 5.8 2.9 2.0 1.6 1.3 1.1 3,578.5 3,019.7 2,505.1 2,030.0 1,794.8 1,586.5 1,381.2 1,170.8 417.0 317.0 200.8 124.4 98.1 83.1 74.3 65.3 117.5 3,336.6 0.2 0.2 0.1 9.97 8.60 6.34 Table 3. “Silver Zone” Pit-constrained Mineral Resource Esmate by Silver Cut-Off Category Ag Cut-off (%) Tonnes (Mt) Ag (g/t) Cu (%) Pb (%) Zn (%) Ag Cu Pb (Mozs) (Mlbs) (MLbs)) 25 35 45 50 55 60 65 70 75 25 35 45 50 55 60 65 70 75 50 25 35 45 21.0 15.9 12.5 11.2 10.1 9.1 8.3 7.5 6.9 10.4 7.3 5.0 4.1 3.4 2.9 2.4 2.0 1.8 15.2 0.01 0.00 0.00 83.6 101.2 117.7 126.6 134.2 142.3 149.7 158.4 166.5 54.9 65.4 77.6 84.0 90.7 96.8 102.9 109.5 115.7 114.9 28.8 0.0 0.0 0.08% 0.10% 0.11% 0.12% 0.13% 0.14% 0.15% 0.15% 0.16% 0.03% 0.04% 0.05% 0.05% 0.05% 0.05% 0.05% 0.05% 0.05% 0.10% 0.07% 0.00% 0.00% 0.5% 0.6% 0.6% 0.6% 0.6% 0.6% 0.7% 0.7% 0.7% 0.2% 0.2% 0.3% 0.3% 0.3% 0.3% 0.3% 0.3% 0.3% 0.5% 0.3% 0.0% 0.0% 2.6% 2.5% 2.5% 2.5% 2.5% 2.5% 2.5% 2.5% 2.4% 1.3% 1.3% 1.3% 1.3% 1.3% 1.3% 1.3% 1.3% 1.3% 2.2% 1.6% 0.0% 0.0% 56.5 51.6 47.3 45.3 43.4 41.7 40.1 38.4 36.9 18.4 15.4 12.4 11.1 9.9 8.9 8.0 7.2 6.5 56.3 0.01 0.00 0.00 37.4 34.4 31.7 30.3 29.1 28.0 26.9 25.6 24.6 7.9 6.6 5.2 4.4 3.6 2.9 2.5 2.2 1.8 34.7 0.02 0.00 0.00 245.8 201.6 168.3 155.0 141.5 129.8 120.0 110.6 101.7 53.2 40.0 27.4 23.2 19.8 17.0 14.0 11.8 10.0 178.2 0.06 0.00 0.00 MEASURED INDICATED TOTAL M&I INFERRED Zn (Mlbs) 1,222.25 869.2 679.2 611.2 548.4 493.2 452.3 409.9 370.9 288.1 208.2 142.4 119.5 98.1 83.0 68.8 56.6 49.8 730.7 0.35 0.00 0.00 The Global Mineral Resources were esmated by Mahew Dumala P.Eng. of Archer Cathro Ltd. by Ordinary Kriging (OK) using Geovia GEMSTM soware in three passes using 10m x 10m x 10m blocks as the SMU size. The classificaon methodology used was that blocks meeng the criteria of Pass 1 would be flagged as Measured; Pass 2 – Indicated; and Pass 3 – Inferred. Silver, copper, lead and zinc were esmated using Ordinary Kriging (OK) on uncapped composited 1.0m grades. 20 NSR values were assigned to blocks within the Mineral Resource and confined to a pit shell generated in While. A $US13.50 NSR cutoff was selected for the global Mineral Resource. The While pit and NSR calculaons assumed a silver price of US$18.00/Troy ounce and a zinc price of US1.20/pound; recoveries of 75% and 41% respecvely; pit slope angles of 55o overall; mining costs of US$1.50/tonne; and Ag & Zn processing costs of US$12.00/tonne. The sub table breakdowns from the global resource was equated using a 50g/t cutoff grade for silver and 6% for Zinc. 1.10 INTERPRETATIONS, CONCLUSIONS AND RECOMMENDATIONS For the next phase of work specifically on the oxide resource the authors recommend that Silver Bull Resources: · · · · · · · · Complete addional metallurgical test work on both the silver and the zinc to confirm recovery parameters. Consider a pilot-plant program to prove the viability of the selected process The next phase work program should include geotechnical drilling to confirm appropriate slope angles for future open pit design work. Connue underground diamond drill work for improved interpretaon and modeling of domains. Detail power and water sources, requirements, and begin all perming processes. Examine the potenal of the silver and zinc zones as stand-alone minable resources. Conduct a Preliminary Economic Assessment (PEA). Connue to explore the property with an emphasis on targeng potenal sulphide targets. The authors esmate that the total cost for the next phase of work on the oxide resource is approximately US$2M. 1.11 OTHER RELEVANT DATA AND INFORMATION Since September 30, 2019, the project has been under an illegal blockade and unable to access the project, by a mining co-operave called Minera Nortenos. The co-operave is demanding payment of a producon royalty, even though no mine is in producon. Despite favorable court rulings in Silver Bull’s favor, the Mexican government has refused to do anything about the blockade, despite its illegal nature. Talks are on going with the co-operave, but to date no reasonable selement has reached. 21 The illegal blockade, and the inability to access the project was directly responsible for South32 terminang its opon agreement with the company on the Sierra Mojada project. A full summary is provided in Secon 21 of this report. 22 2 INTRODUCTION 2.1 TERMS OF REFERENCE This Technical Report dated January 24, 2023, was prepared by Archer, Cathro & Associates (1981) Limited (“AC”) and Silver Bull Resources Inc (“SVB”).

Pennstrom Jr., M.A.; QPMMSA of Pennstrom Consulng Inc. was contracted by Silver Bull in 2013 and 2014 to review the metallurgical tesng programs conducted. Mr. Pennstrom’s work was provided to the Authors by Silver Bull and forms the basis of Secon 13 – Mineral Processing and Metallurgical Tesng. Responsibility for his work has been undertaken by Mr Timothy Barry, MAusIMM(CP), a Qualified Person. No addional metallurgical work has been conducted by Silver Bull since this me. Although copies of the tenure documents, operang licenses, permits, and work contracts were reviewed, an independent verificaon of land tle and tenure was not performed. The Authors have not verified the legality of any underlying agreement(s) that may exist concerning the licenses or other agreement(s) between third pares but has relied on Silver Bull‘s solicitor to have conducted the proper legal due diligence. Informaon on tenure and permits was obtained from Silver Bull. Based on Silver Bull’s legal opinion the current mining law in Mexico allows for the concession to be issued for 50 years. This law was made effecve April 29, 2005 and concessions issued prior to this change in mining law will have the expiraon date of the concession amended to reflect the 50-year period. The Authors have relied on representaons and legal opinions provided by Silver Bull regarding the legal disposion of mining concessions. The Authors have relied completely on Silver Bull regarding all informaon related to the environmental, polical and tax informaon about the project. 27 3 PROPERTY DESCRIPTION AND LOCATION 3.1 LOCATION The Sierra Mojada project is located in the northwestern part of Coahuila State, Mexico, close to the border with Chihuahua State (Figure 1). Access is by paved Highway from the city of Torreon about 250km southwest of the project. The project site is situated about one km south of the village of Esmeralda. The Sierra Mojada Project abuts a major escarpment that forms the northern margin of the Sierra Mojada range. The average elevaon at the site is 1,500masl and is at latude 27°24’ North and longitude 103°43’ West. Silver Bull Resources employs the NAD 27 Zone 13 survey coordinate system on the project. Figure 1. Property Locaon Map 28 3.2 MINERAL CONCESSIONS Silver Bull operates in México through a wholly owned Mexican subsidiary; Minera Metalin S.A. de C.V. All minerals in Mexico are owned by the federal government and mineral rights are granted by solicing mining concessions, which by law have priority over surface land use, but in pracce the concessions owner must have an agreement with the surface owner. See Figures below for the locaon of the regional and deposit scale concessions. Figure 2. Sierra Mojada Mining Concession Map (provided by Silver Bull) 29 Figure 3. Mining Concessions in the immediate Sierra Mojada Project Resource Area (Provided by Silver Bull) The mining concessions held by Silver Bull cover all the mineralized zones with the excepon of one licence 10.47ha in size and as shown in Figure 3. Both the mineralizaon and While Pit used to esmate this resource extend onto this licence, however none of the resource that falls on within this licence is included in this resource esmaon. The only mining operaon currently acve within the area is a small low tonnage dolomite quarry operated by Peñoles near Esmeralda. The quarry is to the south east of the Silver Bull mining concessions. The table below shows the mining concessions currently held by Silver Bull. Total area for these licences excluding the “claim filed” concessions is 9,530.4 ha. The “registered” concessions are 100% owned by a Silver Bull’s wholly owned Mexican subsidiary; Minera Metalin S.A. de C.V. (Minera Metalin). In the concessions with the “purchase opon” status, Minera Metalin has a 100% interest, and the “claim filed” concessions will be 100% owned once granted by the Mexican authories. 30 Table 4.

Silver Bull is in discussions to acquire the surfaces rights for the remaining area. Under Mexican Law if mining right are held, these supersede surface rights, and a “Temporary Occupaon” of ground can be obtained which guarantees access to ground to commence mining acvity. All of Silver Bull’s fixed assets, including offices and buildings are located on land owned by Silver Bull. 31 3.4 ROYALTIES The mining concession is subject to royalty payments amounng to 2% of the mine’s NSR capped at an amount of US$6.875M. Figure 4. Surface Rights of Sierra Mojada 3.5 SECURITY There is currently an illegal blockade on the project stopping access, In the interests of safety, Silver Bull has shut down all operaons unl a reasonable selement has been reached with the group blocking the project. There have been no drug, cartel or gang related security issues on the Sierra Mojada property. The project lies at the end of the pavement of Carretera Estatal 91 going north from Torreón in the western most part of Coahuila state. There are no local connecons to the internaonal border, which is 190 km straight-line distance to the closest point at Big Bend, Texas. 32 3.6 SIGNIFICANT ISSUES There is currently an illegal blockade, stopping access to the project. Silver Bull Surface rights at the eastern end of the deposit are not currently under Silver Bull’s control. In order for the project to proceed Silver Bull will have to secure the surface property rights or acquire a Temporary Occupaon to these areas. 33 4 ACCESSIBILTY, CLIMATE, LOCAL RESOURCES, INFRASTRUCTURE AND PHYSIOGRAPHY The climate is arid and warm. Rainfall is scarce but more prominent in summer, while temperatures are very hot by day and cool at night. The average annual temperature is 14 ºC to 16 ºC, with rainfall of 400 to 500mm per year. The highest daily temperatures are generally recorded in May, with maximum temperatures being moderated somewhat by rainfall during June through October. Freezing occurs from me to me during the winter – parcularly in January and February - although this occurs less than 20 days out of the year in most years. Occasionally there is snow as can be seen in Figure 5. Winds are highly variable, but strong southerly winds coming down from the mountains are common. Streams are ephemeral and wells with acceptable water quality are tens to hundreds of meters deep. (Tuun & AFK 2015) Figure 5. December 2006 - Snow at Sierra Mojada 34 Figure 6. Typical Landscape of Sierra Mojada Project The project is located west of Sierra Madre Oriental on the Mexican Plateau. The terrain is generally flat, with prominent relief formaons of up to 1,500m along the southern boundary of the project site as shown in the Figure 6. The majority of the mineral concessions are located in areas at the base of the cliffs where there is moderate relief with numerous stream forming gullies that erode the surface alluvium. The area is high desert covered by scrub vegetaon; comparable to the Basin and Range in Nevada. Mining operaons are viable throughout the year (Tuun & AFK 2015). 4.1 LOCAL RESOURCES While most of the area peripheral to the project site is used for cale ranching, the village of La Esmeralda and the town of Sierra Mojada (about 4km west of the project camp) can provide local workforce and minor supplies. Both communies offer basic services and for the project and are linked by paved road. Mina Dolomita, the Peñoles dolomite extracon and crushing facility is located at the southeastern boundary of the project. The mine contains waste piles and a 1km long conveyor belt that transports crushed dolomic carbonate aggregate of specific magnesium carbonate grade to their railroad spur for bi-weekly transportaon to the Peñoles Quimica Del Rey plant in Laguna Del Rey. 35 4.2 INFRASTRUCTURE A rail line ulized by Peñoles to transport material to its chemical plant extends west to La Esmeralda. The remains of an older railroad secon extend further to the west and would be easily accessible to old workings and a loading facility located south of La Mesa Blanca right in the center of the Sierra Mojada Camp (Figure 7). The spur line connects the main naonal line which connects Escalon and Monclova. Rail traffic to the east is through Frontera to the United States, via Eagle Pass, Texas, southward to Monterrey, or via the seaport at Altamira/Tampico. Service to the west is also available, as well as to the western USA via El Paso, or to points south connected through Torreón. Although power levels are sufficient for current operaons and exploraon, any development of the project would potenally require addional power supplies to be sourced. The Comisión Federal de Electricidad (English: Federal Electricity Commission) is the Mexican state-owned electricity monopoly, widely known as CFE, which provides service to the area. High voltage (13,400 v) power is available to the vicinity of the head frames of the San Salvador sha (500 KVA), the Encantada sha (300 KVA), and the METALIN shop area (112.5 KVA). (JDS 2013). The project has 5 registered water wells with Con-Agua, the Mexican Authority which controls water rights and distribuon and allows for the company to take up 2.5 million cubic meters of water per annum for mining operaons. There is a paved state highway to site, and a gas line 35km from the project at Quimica Del Rey. 36 Figure 7. Local Infrastructure at Sierra Mojada (Silver Bull 2022) 37 5 HISTORY The following historical summary has been extracted from previous technical reports and informaon provided by Silver Bull. Silver and lead were first discovered by a foraging party in 1879, and mining to 1886 consisted of nave silver, silver chloride, and lead carbonate ores. Aer 1886, silver-lead-zinc-copper sulphate ores within limestone and sandstone units were produced. No accurate producon history has been found for historical mining during this period. Figure 8. Historic Mining at Sierra Mojada Approximately 90 years ago, zinc silicate and zinc carbonate minerals (“Zinc Manto Zone”) were discovered underlying the silver-lead mineralized horizon. The Zinc Manto Zone is predominantly zinc dominated, but with subordinate Lead – rich manto and is principally situated in the footwall rocks of the Sierra Mojada Fault System. Since discovery and up to 1990; zinc, silver, and lead ores were mined from various mines along the strike of the deposit including from the Sierra 38 Mojada property. Ores mined from within these areas were hand sorted and the concentrate shipped mostly to smelters in the United States. Acvity during the period of 1956 to 1990 consisted of operaons by the Mineros Norteños Cooperava and operaons by individual owners and operators of pre-exisng mines. The Mineros Norteños operated the San Salvador, Encantada, Fronteriza, Esmeralda, and Parrena mines, and shipped oxide zinc ore to Zinc Naonal’s smelter in Monterrey, while copper and silver ore were shipped to smelters in Mexico and the United States. The principal mines operated by individuals and lessors were the Veta Rica, Deonea, Juárez, Volcán I and II, Once, San Antonio, San José, San Buena, Monterrey, Vasquez III, Tiro K, El Indio and Poder de Dios. The individual operators were mainly local residents, such as the Farias, Espinoza, and Valdez families. In the early 1990’s, Kenneco Copper Corporaon (“Kenneco”) had a joint venture agreement involving USMX’s Sierra Mojada concessions. Kenneco terminated the joint venture in approximately 1995. Metalline entered into a Joint Exploraon and Development Agreement with USMX in July 1996 involving USMX’s Sierra Mojada concessions. In 1998, Metalline purchased the Sierra Mojada and the USMX concessions and the Joint Exploraon and Development Agreement was terminated. Metalline also purchased the Esmeralda, Esmeralda I, Unificación Mineros Norteños, Volcán, La Blanca and Fortuna concessions, and conducted exploraon for copper and silver mineralizaon from 1997 through 1999. During this period, exploraon consisted of reverse circulaon (“RC”) drilling which intersected significant zinc mineralizaon. In October of 1999, Metalline entered into a joint venture with North Limited of Melbourne, Australia (now Rio Tinto). Exploraon by North Limited consisted of underground channel samples in addion to surface RC and diamond drilling. North Limited withdrew from the joint venture in October 2000. A joint venture agreement was made with Peñoles in November 2001. The agreement allowed Peñoles to acquire 60% of the project by compleng a bankable Feasibility Study and making annual payments to Metalline. During 2002, Peñoles conducted an underground exploraon program consisng of driving raises through the oxide Zinc Manto, diamond drilling, connuaon of the percussion drilling, and channel sampling of the oxide zinc workings (stopes and dris) previously started by Metalline in 1999 and connued by North in 2000 and Metalline during 2001. 39 The workings operated by the Norteños Cooperava in the Zinc Manto allow access to the enre Zinc Manto in the San Salvador, Encantada, and Fronteriza mine operaons. The objecve of Peñoles`s 2002 program, in addion to evaluang the Zinc Manto mineralizaon, was to compare the quality and consistency of sampling methods. Peñoles developed diamond drill sites in the San Salvador and Encantada mines. It also developed raises through the vercal extent of the Zinc Manto. Bulk samples of raise muck and channel samples of the raise walls were collected at one meter intervals. Percussion and diamond drill holes were drilled parallel to the raises and also sampled at one meter intervals. The Peñoles 2003 program connued the underground channel sampling and included percussion and diamond drilling from the surface. In addion to drilling the manto along its extent in the three mines, Peñoles conducted step out drilling to the east and west. Peñoles drilled holes on fences spaced 200 m apart east of the Fronteriza mine toward the Oriental mine, a distance of nearly 2 km. The holes were spaced 50 to 100 m in a north-south direcon along the fences. To the west Peñoles followed up the North Limited drilling in the vicinity of the San Antonio mine, 2 km west, which confirmed and extended the mineralizaon. In December 2003, the joint venture was terminated by mutual consent between Peñoles and Metalline. Peñoles had other projects it preferred to fund and Metalline was interested in reacquiring a 100% interest in the project. From 2003 to April 2010, Metalline connued sampling numerous underground workings through channel and grab samples as well as compleng underground and surface drill holes exploring the zinc-silver mineralizaon. Subsequent to the merger with Dome Ventures in April 2010 underground exploraon of the Zinc Zone was terminated. Focus was switched to a surface diamond drill program exploring near surface low grade bulk tonnage silver-zinc mineralizaon or the same style of mineralizaon above and up-dip from the hemimorphite zinc mineralizaon. (JDS 2013) 5.1 PAST PRODUCTION To date Silver Bull has esmated that over 150km of underground workings have been surveyed on the project. This represents approximately 4 million tonnes of development and 10 million short tons of silver, zinc, lead, and copper ores. 40 From 1897 to about 1905, small quanes of lead ore were smelted on site, and remnants of the smelter are sll visible near the core logging facility (see Figure 9). At various mes historically, zinc oxides ores were shipped to ferlizer plants in the U.S. and Mexico. Esmates from 1931 put producon along the mineralized trend, of which the Sierra Mojada property is a subset, at approximately 5 million short tons (all of the following will be short tons). That compares with Shaw, who in his 1922 AIME paper esmated that producon to 1920 was 3 to 3.5 million tons of lead-silver ores; and 1.5 to 2 million tons of Ag and Cu-Ag ores. Based on fragmented records, anecdotal evidence and stope volumes, perhaps 900,000 tons of addional oxide zinc may have been mined from Red Zinc and White Zinc areas on the Sierra Mojada property. Significant producon occurred between 1920 and 1950 from the district with the involvement of major internaonal mining companies operang small daily tonnage mines during that period. (JDS 2013) Mineros Norteños mined in both the red and white zinc zones unl the late 1990’s. Much of the material was converted to ZnO through the use of two on-site kilns (Figure 9). Esmates indicate that ~120 tonnes per day from each kiln was produced and shipped to Mexican plants such as Zinc Nacionale. The mining rate from the three acve shas was esmated at ~250t/d at a cutoff of 25% Zn. (pers comm Juan Manuel Lopez Ramirez 2018). 41 Figure 9. Sierra Mojada Historical Lead Smelng Kilns – September 2010. These were removed in 2013. 42 Most of the workings are accessed through vercal shas although there are a few adits and open stopes also present. For safety reasons, shas have been barricaded and locaons surveyed. The head frames at San Salvador, Fronteriza and Centenario have been maintained and are used regularly. 5.2 HISTORICAL RESOURCE ESTIMATES Figure 10. Known Historic Mine Shas While the area has hosted prolonged but small scale mining acvity for over 100 years there is no exisng reliable historical resource esmate for the various manto deposits. Prior S-K 1300 compliant mineral resources have been prepared for the property; namely a mineral resource prepared by PAH in January 2010 covering the Shallow Silver Zone and the Zinc Manto Zone and a mineral resource esmate prepared by Simpson and Nilsson in April 2011 covering the Shallow Silver Zone only (Table 5). These esmates are documented in technical reports listed in the Reference secon of this report and available on SEDAR. The esmates are reliable and relevant to the property. The Zinc Manto has been parally re-esmated by SRK, as such the PAH esmate for the Zinc Manto is no longer considered current and should not be relied upon. (JDS 2013) 43 Table 5.

The other two zones are the Western Zone and the Trans Mexican Volcanic belt. The Eastern Zone represents a passive plate margin relave to the Western Zone which documents a convergent plate margin, and is composed of three major lithostragraphic terrains; the Coahuila, Maya, and Sierra Madre. The boundary between the Eastern and Western terrains is in Chihuahua just west of the Sierra Mojada project area. Within the Eastern Zone, the project is located in the Coahuila terrain. 6.1.1Coahuila Terrain Basement rocks in the poron of the Coahuila terrain containing the Sierra Mojada district are Late Paleozoic in age. The Coahuila basement block is composed of moderately metamorphosed flysch and unmetamorphosed andesic volcanic rocks, cut by granite and granodiorite intrusive rocks of Permian to Triassic age The Coahuila block is bounded to the northeast by the San Marcos fault system and to the south by the Torreón-Monterrey lineament, parallel to the Sonora-Mojave megashear (Figure 11). 45 Figure 11. Major Tectonic Elements of Northeastern Mexico Note: The Sierra Mojada project area is outlined in red, the San Marcos Fault Zone (SMF) in green. Major tectonic elements of northeastern Mexico show the regional sinistral shear couple between the San Marcos (SMF) and the Rio Bravo-La Babia (LBF) transcurrent fault zones; major components of the Mohave-Sonora megashear MSM). Also shown is the Coahuila block (CB), the La Mula Island (LMI), the Coahuila-Texas craton (CCT) and the Ouachita-Marathon Orogenic Belt (OMOB) which marks the boundary between the Western and Eastern litho-tectonic provinces in Mexico (Gryger 2010). 46 The basement rocks of the Coahuila block were cut by Permian to Triassic aged granic and granodioric intrusions. These intrusive units represent the roots of an island arc system produced south of the Ouachita-Marathon orogenic belt. Permian-Triassic intrusive rocks of similar composion to those found within the Coahuila block occur within the Sabinas basin along the La Mula and Monclava uplis. The intrusive units likely acted as basement high within the basin during the Jurassic and Cretaceous. The Coahuila block was the source of siliciclasc detritus deposited along the Jurassic and Early Cretaceous in the Sabinas Basin following regional deformaon along the San Marcos fault system (Figure 12). Note: Figure is showing Laramide folding and the posion of the basin bounding faults; the San Marcos and La Babia systems (Gryger, 2010). Figure 12. Cross Secons through the Sabina Basin 47 6.1.2 Sabinas Basin The Sabinas basin formed during the Jurassic opening of the Gulf of Mexico and contains over 6,000 m of Jurassic to Cretaceous connental red- beds, evaporites, and carbonate rocks. The basin formed between the Coahuila block to the south and the Coahuila-Texas craton to the northeast. A post-riing marine transgression resulted in deposion of extensive Middle Jurassic to Late Cretaceous carbonate rocks throughout the region. Although the orientaons of sedimentary basins in northeastern Mexico were structurally controlled, basin-bounding structures were likely inacve during the me of carbonate deposion. The Sabinas Basin is prolific in its producon and potenal of hydrocarbon, primarily natural gas, coal, and coal-bed methane. It is also the source of metal-bearing brines linked to lead-zinc, coppersilver, barite, stronum, and fluorine mineralizaon in SEDEX related mineral deposits; in skarn related mineral deposits and Laramide age intrusive rocks; and in CRD type replacement deposits. The potenal for sulfur and potash remains speculave. 6.1.3 Regional Structure The Coahuila region contains three major northwest-trending structures as presented in Figures 11 and 12: • Mojave-Sonora megashear • • Torreón-Monterrey lineament San Marcos-Rio Bravo (Babia) shear couple The Mojave-Sonora megashear was proposed by Silver and Anderson (1974) to explain an 800 km sinistral offset between basement rocks in northern Mexico and southern California. This shear zone is interpreted to have formed from a series of intraconnental transform faults that were acve during the Late Triassic to Middle Jurassic. The Torreón-Monterrey lineament is a west-northwest-trending structure that forms the southern boundary of the Coahuila basement block and is the southeastern extension of the Mojave-Sonora megashear. It displays regional scale le-lateral displacement of up to 400 km Movement along the Torreón-Monterrey lineament appears to have occurred primarily between the Middle Triassic and Late Jurassic. The north-northwest striking San Marcos-Rio Bravo sinistral shear couple was acve during the Jurassic, Early Cretaceous, and Terary and has a surface trace length of at least 1000km according to Floe, et al 2008. This shear couple is responsible for a disnct system of conjugate normal faults in the region which strike north-south to north 70 degrees east. 48 The San Marcos fault component of this system exhibits a minimum of four recorded movements and begins with an early normal movement with later le-lateral strike-slip reverse movements beginning in the early Terary. Inial movement along the San Marcos fault has been aributed to deformaon along the Torreón-Monterrey lineament and the Mojave-Sonora megashear together with subsequent isostac adjustment due to crustal thickening during the Jurassic. The thrust component of the San Marcos fault is locally referred to as the Sierra Mojada thrust and the corresponding thrust movement on the Rio Bravo fault to the north is referred to as the Babia thrust zone. The San Marcos fault is northeast dipping and is believed to cut the enre crust while documented off sets are about 100m in the Sierra Mojada district, but variable region wide. Movement along the San Marcos fault system resulted in the deposion of Cretaceous age connental redbed and carbonate units north of the fault. The redbed units include the San Marcos Formaon and the Upper Conglomerate units. The carbonate units include the La Pena and Aurora Formaon, all in the Sierra Mojada district. Reacvaon of the San Marcos fault occurred during the Early Pliocene and resulted in a series of secondary faults with east-west to north-south orientaons in western Coahuila and southeastern Chihuahua. The deep seated San Marcos fault zone has also been the structural guide to Laramide – Pleistocene age igneous acvity along its length including the Carmago volcanic field 100 km to the northwest of the Sierra Mojada district, the Quatro Cienegas thermal area 150 km to the southeast of the Sierra Mojada, as well as the igneous intrusions believed to be the source of the mineralizaon in the Sierra Mojada district. The Seveir-Laramide orogeny marks a period of major mountain building along a northwest trending front throughout the North American connent. The ming of the Laramide orogeny varies across North America, but it is broadly aributed to the late Cretaceous to early Paleocene. In northeastern Mexico, the Laramide orogeny resulted in the reacvaons of Early Mesozoic ri-related basement faults. Cretaceous strata situated on the Coahuila block experienced low intensity deformaon forming a broad, southeast-plunging anclinal dome. Laramide deformaon also formed the Sierra Madre Oriental fold and thrust belt to the south of the Coahuila block and the Coahuila fold belt to the north of the Coahuila block in the Sabinas Basin 49 6.2 PROPERTY GEOLOGY 6.2.1 Sierra Mojada Stragraphy The rocks at Sierra Mojada record an Early Cretaceous transgression beginning with subaerial redbeds and near shore beach sandstones followed by carbonate rocks deposited in shoal, lagoonal, shelf, and plaorm environments. At Sierra Mojada, Lower Cretaceous rocks are overlain by younger redbed and breccia units as shown by Gryger in Figure 13, which separates the regional stragraphy into the allochthonous and autochthonous blocks. 50 Figure 13. Time Correlaon Diagram of the Sabinas Basin Stragraphy 51 Stockhausen (2012) refined the local stragraphy as employed on the Sierra Mojada Project in Figure 14 and renamed a disnct and local poron of what was historically called the Cretaceous San Marcos formaon, as the Terary Upper Conglomerate. Note: The stragraphy as employed on the Sierra Mojada project by Stockhausen (2012) who conducted an independent invesgaon of the Upper Conglomerate unit. As noted in text, the Upper Aurora formaon is oen known as the Georgetown formaon of the gulf coast, but the name has lost its usage in Mexico. The Upper Aurora is a diagenec dolomite unit mined by Peñoles at Sierra Mojada for its magnesium content, and is locally referred to as the Peñoles dolomite and Mina Dolomita. Figure 14. Stragraphy on the Sierra Mojada Project by Stockhausen (2012) 6.2.2 Allochthonous Stragraphy 6.2.2.1 San Marcos Formaon The San Marcos Formaon has been described throughout Coahuila and has been the focus of several invesgaons in the Sierra Mojada district as noted by Stockhausen (2012). Regionally within the Coahuila terrain, the San Marcos Formaon is up to 1,000m thick with the thickest secons present north of the San Marcos fault which indicates that this fault was acve during deposion of the unit. In the Sierra Mojada district, the San Marcos Formaon has a thickness of approximately 70m in drill core. The unit consists of Lower Cretaceous alluvial strata composed of conglomerates containing andesic volcanic pebbles within a siliceous matrix and several meter thick siltstone units (Figure 14). 52 6.2.2.2 La Mula Formaon The La Mula Formaon occurs throughout northeastern Mexico and forms an unconformable surface above the San Marcos Formaon. The La Mula is believed to represent a change from an alluvial deposional environment to a near shore beach environment. In the Sierra Mojada district the La Mula Formaon is known as the Sierra Mojada Sandstone (Figure 14). It crops out within an overturned sequence south of the town of Sierra Mojada and consists of fine- to medium-grained, subrounded to rounded, well sorted quartz sandstone up to 25m in thickness. The siliciclasc rocks of the La Mula and San Marcos Formaons have been historically targeted for sediment-hosted straform copper deposits by several companies. 6.2.2.3 Cupido Formaon The Cupido Formaon is the lowest stragraphic carbonate unit of Mesozoic age throughout much of northeastern Mexico. In the Sierra Mojada district the contact between the La Mula Formaon and the overlying Cupido Formaon is gradaonal and is approximately 90m thick. The basal poron of the unit contains medium grey colored skeletal grainstone and wackestone with local mudstones that display a moderate degree of bioturbaon. These strata are thought to have been deposited in restricted lagoonal and peridal environments. The upper poron of the Cupido Formaon at Sierra Mojada contains brown-grey packstones and grainstones with some oolic lenses suggesve of deposion in a high energy shoal deposional environment. Note: Sabinas Basin stragraphy with descripons, separated into allochthonous and autochthonous blocks. Not all units are documented at Sierra Mojada (Gryger 2010). 6.2.2.4 Upper Conglomerate The Terary age Upper Conglomerate unit is arguably the most controversial lithology in the district (Figure 14). Various companies and authors have referred to the unit as the Menchaca formaon, Upper San Marcos formaon, ferruginous breccia, limonite breccia, residual breccia, Ralph and “X”. On the project, the Upper Conglomerate is defined and logged separately from the generic ferruginous breccia (Fbx) which is described as an alteraon facies under Figure 14. The unit is significant in that it is a major host rock to high grade silver-copper mineralizaon in the Sierra Mojada district, (Figure 15). 53 Figure 15. Ferruginous Breccia Note: Ferruginous breccia above limestone and below San Marcos formaon conglomerate (purple) from the Norteña area near the Encantada sha (Thorson 2010). Stockhausen (2012) and Thorson (2010) refer to the Upper Conglomerate as an unconformable surface and interpret the unit to be a local scale, surface karst feature. Observaons underground though, show a consistent associaon with low angle faulng. An alternave and most likely interpretaon is that the Upper Conglomerate is in fact the San Marcos Formaon that has been thrust over the top of the younger limestone sequence by low-angle thrust faults and has locally been mixed with younger sediments in stream beds and outwash plains. 6.2.2.5 Limestone Megabreccia The Limestone Megabreccia is the youngest stragraphic unit observed at Sierra Mojada (Figure 14). The unit is a clast-supported breccia composed of variably weathered, angular to subrounded, pebble to boulder sized clasts of Aurora Formaon and Upper Aurora Formaon limestone in a matrix of calcite with lesser quartz. The Limestone Megabreccia differs from the Cretaceous carbonate units in displaying highly variable orientaons of the limestone clasts and abundant joints, but does not appear to be cut by faults. Unlike Quaternary alluvium in the district, the Limestone Megabreccia contains only limestone blocks, lacks well-rounded clasts, contains minor to no shale to silt matrix material, and has a much higher resistance to weathering. It is separated from the Upper Conglomerate by a detachment or low angle fault. 54 6.2.3 Autocthonous Stragraphy 6.2.3.1 Coahuila Basement Complex Within the Coahuila basement complex at Sierra Mojada, the project lies at the juxtaposion of three important litho-tectonic elements; the Permian-Triassic Coahuila basement block, the Cretaceous Sabinas Basin, and the San Marcos-Rio Bravo Triassic-Terary transcurrent fault zone and associated conjugate structures. The Rio Bravo fault zone is also known as the La Babia fault zone. 6.2.3.2 La Casita Formaon The La Casita formaon is not known in the Sierra Mojada district, but is well-known in the regional stragraphy. 6.2.3.3 Cupido Formaon The Cupido formaon in the autochthonous block is the same lagoonal-peridal facies as in the allochthonous block 6.2.3.4 La Peña Formaon The La Peña Formaon overlies the Cupido Formaon throughout northern Mexico. In the Sierra Mojada district the formaon consists of a series of coarsening-upward cyclical limestone units. The base of each cycle is typically a dark grey to black colored carbonaceous mudstone. Tops of individual cycles generally are brownish grey packstone or wackstone with coarser-grained strata and oen contain large fossils. The upper poron of the La Peña Formaon is less fossiliferous and consists of thick beds of light grey packstone and wackestone. The total thickness of the La Peña Formaon at Sierra Mojada is approximately 60m. The cyclical nature and relave abundance of argillaceous material in the La Peña Formaon carbonate rocks at Sierra Mojada suggest that they were deposited in a lagoonal environment. 6.2.3.5 Aurora Formaon The overlying Aurora Formaon is the principal host rock for the sulfide and oxide mineral deposits at Sierra Mojada (Figure 14). The Aurora Formaon crops out along the cliffs at the southern boundary of the Sierra Mojada valley. Structural deformaon of the Aurora Formaon at Sierra Mojada has made it difficult to determine the total thickness of the unit and it is thermally metamorphosed in thin secon throughout the district. However geological mapping and drill secons suggest it has a thickness of approximately 500m. The basal poron of the Aurora Formaon contains mostly grey to brown micric mudstone and wackestone with some fine-grained fossil debris. The basal poron of the formaon grades upwards to disnctly more fossiliferous, medium grey wackestone and grainstone with disconnuous intervals containing lobate chert nodules and minor mudstone. The Aurora Formaon sequence is typical of open marine plaorm to shallow slope environments. 55 The Aurora Formaon at Sierra Mojada is overlain by the Upper Aurora Formaon. This unit contains fossiliferous grainstone and wackestone similar to much of the limestone in the Aurora Formaon. The unit has previously been termed the Georgetown Formaon in some reports (Hodder, 2001, internal report.). However, the Georgetown Formaon is the stragraphic equivalent to the Upper Aurora Formaon along the Texas Gulf coast and this nomenclature is general not ulized in northeastern Mexico. The Upper Aurora is regionally a diagenec dolomite and is locally referred to as the Peñoles Dolomite due to the local open pit magnesia mine operated by Peñoles known as Mina Dolomita. There is no metallic mineralizaon know to be associated with this unit besides the magnesium. 6.3 SIERRA MOJADA STRUCTURE The Sierra Mojada district is dominated by three sets of structures, each with a unique influence on the geology and mineralizaon of the project. These structures are related to the San Marcos-La Babia shear couple regionally and later basin-and-range extension (Figure 16) and locally present a structurally “dense” architecture which has had a profound influence in the amount and styles of mineralizaon present. 6.3.1 San Marcos Fault The San Marcos fault zone is the oldest fault present in the district. The San Marcos, regionally, records at least four separate movements from the Jurassic to the early Terary. From Jurassic through early Cretaceous me, the San Marcos recorded three separate periods of normal movement, down-dip and stepping basin-ward towards the north. In the Sierra Mojada district, the San Marcos faults strike N78 West and dips at 65 degrees to the North. The northern most, and most recent step records a 100m down-drop. During the Laramide Orogeny the San Marcos reacvated as a reverse fault, with le lateral-oblique slip movement from the northeast. Locally, this reverse movement is referred to as the Sierra Mojada thrust fault, due to the prominent exposures underground. Some observers have suggested that the low-angle structures represent a detachment surface. In the Sierra Mojada district, the reverse movement surface varies from 0 to 60 degrees to the north and “roles” in several locaons, along with back thrusts dipping to the south. Offsets are from 6 to 45 meters. The early normal faults related to the San Marcos system are thus over-ridden by the later reverse movements. This period of reverse movement was noted on the La Babia fault zone on the north side of the Sabinas Basin. 56 6.3.2 North East Structures Cung the San Marcos structures are a series of northeast trending structures exemplified by the Callavasas, Parreña, and Veta Rica faults, which are believed to be conjugate structures related to the San Marcos-La Babia shear couple. Throughout northern Mexico, northeast structures are associated with mineralizaon from depth and at Sierra Mojada these northeast structures are believed to be the original sources of hydrothermal mineralizaon in the district. The northeast structures a typically normal and high angle, dipping 90 to 65 degrees and down- dropped to the southeast. Off sets are not well documented due to later structural off sets and mineralizaon. 6.3.3 North-South Structures The youngest structures in the district are normal high angle structures varying from 0 to 20 degrees strike, 90 to 55 degrees dip and are down- dropped to the east and west, forming a series of horst and graben structures across the district. These structures are believed to be related to basin-and-range movements and typically show offsets of 5 to 25 meters. The North-South structures are important at Sierra Mojada as they are a major inheritor of remobilized supergene and oxide mineralizaon and many of the historic workings trace these structures. Figures 16 to 22 include a new and revised geologic map of the district (aer Israel 2013 & 2014) with representave cross secons and long secon through each of the three main porons of the mineralizaon. 57 Figure 16.

Against this backdrop, mineralizaon at Sierra Mojada is directly associated with extensive, hydrothermal dolomizaon and moderate to strong silicificaon, both of which occurred prior to and during primary hypogene sulfide mineralizaon. The hydrothermal alteraon observed at Sierra Mojada is typical of many high-temperature, carbonate-hosted Ag-Pb-Zn-(Cu) deposits in northern Mexico (Megaw et al., 1988). Stockhausen (2012) documents disnct zones of intense sericite alteraon associated with sulfide mineralizaon. This has been interpreted to represent the distal expression of felsite intrusive acvity. 6.4.1 Diagenc Dolomite To the east of the Sierra Mojada district the carbonate secon has been pervasively dolomized, apparently along northeast-trending faults. This area is the site of the acve Peñoles dolomite quarry. The Aurora Formaon is also pervasively dolomized in the western poron of the district, in the area of overturned secon near the Sierra Mojada village. Diagenec dolomizaon represents the introducon of brines from adjacent evaporite-rich basins and is not known to carry base or precious metal mineralizaon but is believed to be part of the host rock preparaon stage for later metals mineralizaon. 6.4.2 Epigenec Dolomite Irregular pods of completely hydrothermally altered dolomized limestone surrounded by zones of parally diaigenec dolomized limestone occur in outcrop throughout the Sierra Mojada district. These dolomized zones may be up to tens of meters thick and occur both along northeast trending faults and along the upper contact of the carbonate secon with overlying Upper Conglomerate. The Sierra Mojada sulfide bodies occur primarily but not exclusively within dolomized horizons. Hydrothermal dolomite represents the influx of higher temperature hydrothermal fluids prior to and during hypogene sulfide mineralizaon. At Sierra Mojada, hydrothermal dolomizaon is expressed by a disnct tan to pink colored, fracture controlled alteraon throughout the district. 6.4.3 Silicificaon Two phases of silicificaon are noted at Sierra Mojada, an early pre-sulfide mineral phase, and a late syn- to post-sulfide mineral phase. The early phase affects carbonate rocks throughout the Sierra Mojada district, especially those within or adjacent to fault zones, and display varying degrees of silicificaon and jasperoid development. Limestone clasts in tectonic, dolomite, and karst breccias are frequently pervasively replaced by very fine-grained, light grey to dark blue, anhedral quartz, something noted in all petrographic work conducted on the project. 65 Early fine-grained silicified limestone is locally cut by later medium- to coarse-grained, subhedral quartz veins that occur along faults and at the contact with the Upper Conglomerate. This coarsegrained quartz is commonly associated with lead, zinc, silver, copper, and iron sulfide and oxide minerals and is spaally associated with zones containing iron- and magnesium-rich replacive carbonate minerals and sulfides or their oxidized products. Typically there is a decrease in silica content moving outward from the structures, something noted in the district dang back to 1901 (Chisholm 1901) Silicificaon is not common within high-temperature, carbonate-hosted Ag-Pb-Zn-(Cu) deposits in northern Mexico and is only noted at the Charcas, Santa Eulalia, La Encantada, and Sierra Mojada deposits (Megaw et al., 1988). 6.4.4 Sericizaon Sericite is commonly present in the ferruginous breccia and within the Upper Conglomerate. Areas containing abundant sericite occur above northeast-trending faults near the historic Veta Rica workings and in the deeper working below the San Salvador and Fronteriza sha areas. The formaon of sericized zones well-up into the Upper Conglomerate indicates that this alteraon clearly post-dates the major period of sulfide mineralizaon at Sierra Mojada. Sericizaon of the Upper Conglomerate and ferruginous breccia may represent connued movement of hydrothermal fluids, or a second phase of hydrothermal alteraon, along and above major structural pathways. Sericizaon is relavely uncommon in the Mexican high-temperature, carbonate-hosted Ag-PbZn-(Cu) deposits. One of the few deposits with significant sericizaon is Santa Eulalia where igneous rocks along mineralized faults are altered to massive sericite with arsenopyrite. 6.4.5 Carbonate Alteraon Two phases of carbonate alteraon are noted at Sierra Mojada, and early pre-and syn-mineral phase and a late phase associated with ongoing supergene processes. The hydrothermal dolomite found throughout the district is cut by a later assemblage of ferroan to magnesian-rich replacement carbonate minerals, which occur along northeast-trending faults and at the upper contact of the carbonate secon. This assemblage of ankerite, siderite, and magnesite locally cuts and replaces diagenec dolomite and previously undolomized limestone. 66 The carbonate minerals are fine-grained and are relavely similar in grain size to earlier diagenec dolomite. They display pink to red colors at surface but have a pale grey color where unoxidized. These carbonate minerals also may be enriched in lead and stronum and commonly display abundant very fine-grained dendric manganese oxide minerals. The iron- and magnesium-rich carbonate minerals are intergrown with iron and base metal sulfides and barite indicang they were precipitated during the inial mineralizaon event (Renaud and Pietrzak, 2010,). The red and pink carbonate minerals are commonly intergrown with iron-oxide and zinc-oxide minerals. Late calcite veinlets occur throughout the Sierra Mojada district, but are most prevalent along the Sierra Mojada fault zone. The calcite veinlets are typically 1-20cm wide and cut carbonate rocks, the ferruginous breccia, and the Upper Conglomerate. The calcite in these veinlets is fine- grained, anhedral, and commonly intergrown with zinc-, lead-, and iron oxide minerals and acanthite; it may contain inclusions of barite (Renaud and Pietrzak, 2011). Coarse-grained calcite with normal to zincian composions also locally replaces limestone, silicified limestone, dolomite, and iron- and magnesium-rich replacive carbonate rocks, as well as the matrix of the ferruginous breccia adjacent to zones containing late calcite veinlets. Calcite veinlets crosscut sericized Upper Conglomerate rocks indicang that this alteraon event occurred aer sericizaon. These calcite veinlets and replacive calcite zones were just recently formed and are interpreted to be ongoing supergene processes. 6.4.6 Argillic Alteraon Argillic alteraon zones are found throughout the Sierra Mojada district at the contact between Cretaceous carbonate rocks and the Upper Conglomerate. These light grey and tan to tan-brown zones are clay-rich. Based on x-ray diffracon (XRD) analyses these zones are composed of kaolinite, illite, and halloysite in addion to fine-grained quartz, limonite, hemate, and calcite. Tan-brown intervals contain more abundant clay relave to the light grey colored, fine-grained quartz-rich material. The ferruginous breccia contains varying abundances of intersal kaolinite and illite with minor halloysite surrounding quartz and carbonate rock clasts, however the ming of formaon of the ferruginous breccia and clay is unclear (Renaud and Pietrzak, 2010). 6.4.7 Ferruginous Breccia The Ferruginous Breccia is treated here as a disnct alteraon facies even though in core logging it is treated as a separate lithology, due to its direct associaon with mineralizaon. The unit may actually be comprised of a mixture of Upper Conglomerate, Aurora Formaon dolomite and limestone, karst breccia, and limonite breccia. Clasts of medium- to coarse-grained, sub-rounded limonite aer sulfide contain elevated concentraons of silver and zinc. Clast shape suggests that they are detrital rather than represenng in-situ sulfide precipitaon. The presence of both sulfiderich and oxide-rich clasts indicates that the ferruginous breccia formed aer both the hydrothermal event responsible for sulfide precipitaon and supergene weathering of porons of the sulfide replacement bodies. 67 The base of the ferruginous breccia is commonly highly irregular. Ferruginous breccia also fills fractures extending downward approximately 7m into the carbonate sequence. These fractures may contain large, angular, cobble-sized limestone and replacive carbonate mineral clasts. Addionally, the ferruginous breccia contains silicified carbonate clasts indicang that this finegrained silicificaon event took place prior to karsficaon. The ferruginous breccia also occurs beneath fine-grained traverne in karst cavies within the limestone sequence. Thus, the ferruginous breccia appears to represent both a surficial deposit formed by chemical and mechanical weathering of carbonate rocks and karst-fill material (Thorson, 2010). The ferruginous breccia is commonly overlain by the Upper Conglomerate. In some areas lenses of ferruginous breccia are interlayered with lenses of Upper Conglomerate suggesng these units formed synchronously. The ferruginous breccia has not been idenfied outside of the Sierra Mojada district. The ferruginous breccia at Sierra Mojada is interpreted to represent surficial oxidaon of exposed sulfide replacement bodies in the carbonate sequence as well as infill of karst cavies formed by both normal weathering and acid generated during sulfide oxidaon. 68 Note: Ferruginous breccia above limestone and below San Marcos formaon conglomerate (purple) from the Norteña area near the Encantada sha (Thorson 2010). Figure 23. Ferruginous Breccia 6.5 MINERALIZATION Sierra Mojada consists of two important and diverse mineralizing models, accentuated by a locally dense structural architecture and are detailed in Chapter 8.0, Deposit Type: Development of a major Carbonate Replacement Deposit (CRD) of lead-zinc-silver (copper), distal to the source intrusion. The oxidaon, supergene enrichment, and second oxidaon of the original sulfide deposit leading to the mineralizaon of current interest and resource development. 69 There are essenally two overlapping mineralized secons to the Sierra Mojada district: The Silver Zone also known as the Shallow Silver Zone (SSZ), also known as the Polymetallic manto of historic reference. The Zinc Zone also known as the Base Metal Manto (BMM). The BMM is subdivided into three further zones for descripve purpose; the Pb Manto (Carbonate Manto of historic reference), the Red Zinc Manto (Iron Oxide Manto of historic reference), and the White Zinc Manto. 6.5.1 Shallow Silver Zone (Silver Zone) The Shallow Silver Zone (SSZ), outcrops on the surface on the west end of the district and dips under colluvial cover towards the east at about 10 degrees. The zone is ~3.3km in length, up to 1km in width, and 100 to 300m thick. The SSZ is hosted in breccias of the Terary Upper Conglomerate unit, the ferruginous breccia, and in reacve dolomite and limestone of the Cretaceous Aurora Formaon. Significantly, mineralizaon is also controlled by the dense array of structures in the district. Due to these structural and lithologic controls, mineralizaon develops in four configuraons: Straform mantos, primarily in reacve dolomite horizons and associated karst breccia features. High-grade (>100g/t) veins, primarily faults and chimneys related to the mixed structural architecture of low angle and high angle faults. Unconformity controlled breccia mineralizaon related to the Cretaceous-Terary weathering surface, although the unconformity demonstrates low-angle movement in many localies. Disseminated replacement mineralizaon between the mantos and structures. 6.5.2 Base Metal Mineralizaon (Zinc Zone) Mineralizaon within the BMM begins with the Lead zone in the highest stragraphic posion, followed by the Red Zinc zone, and the White Zinc zone. BMM mineralizaon is primarily in manto configuraons and each zone contains subordinate amounts of mineralizaon related to the other mantos described. All of the manto mineralizaon dips towards the east at 10 degrees and are controlled by dolomite and subordinate limestone host rocks within the middle Aurora Formaon. The manto mineralizaon developed first from pyrite-sphalerite-galena semi-to massive sulfide mineralizaon followed by oxidaon and supergene enrichment by the processes detailed by Megaw (2009), Borg (2009), and Reichert (2009). 70 6.5.2.1 Lead Zone Discussion of the Lead zone is included to complete the geology and mineralizaon, as well as history of the project. Lile of the Lead zone is included in the current resource calculaon, but is considered a future underground exploraon target for silver. Most supergene mineralizaon originated in the hypogene mineralizaon of the Lead zone mantos. The Lead zone was the original mineral discovery in the Sierra Mojada district and sustained mining in the district for the first 20 years unl its exhauson in 1905. The manto was in what was historically known as the “Snake”, “Manto”, and “Scraggly” beds (Haywood and Tripplet, 1931) of the now defined middle Aurora Formaon, and located stragraphically above the Red Zinc zone. The Lead zone was mined connuously for 4km of strike length, 30 meters of width and up to 6m in height. The lead zone graded 15% lead, 12 ounces per ton of silver, and produced 3.5 million tons of ore (Shaw, 1922) from cerrusite-anglesite, chlorargyrite and nave silver. Mineralizaon was centered on the northeast striking Parreña structure and was accessed through the Parreña tunnel located near the current core shack. 6.5.2.2 Red Zinc Zone The Red Zinc zone is a connuous manto some 2,500m along strike, up to 200m wide, and up to 160 m thick. It averages about 80 m in thickness and about 130m in width. The mineralizaon follows reacve dolomite host rocks and karst fill breccia historically known as the “Santa Getrudia, Hallazgo, and North Encantada” (Haywood and Triple, 1931) horizons in the middle Aurora Formaon. The manto dips to the east at about 10 degrees following the dip of the local stragraphy and is located in the footwall of the Sierra Mojada fault. Mineralizaon consists of massive hemimorphite (Zn₄Si₂)O₇(OH)₂·H₂O), with subordinate amounts of smithsonite (ZnCO₃) and minor hydrozincite (Zn₅(CO₃)₂(OH)₆). The Red Zinc manto is admixed with strong iron-oxide with minor manganese oxide imparng a red color to the zone. Massive red zinc manto mineralizaon is surrounded by a halo of fault and fracture controlled red zinc a result of supergene processes, primarily but not restricted to the footwall. The mineralizaon is vuggy and shows replacement of zebra textures as well as laminated cavefloor and so-sediment deformaon. Relic pyrite, galena, and sphalerite have been noted although the overall level of oxidaon is strongly pervasive. The lead oxide plaernite (PbO₂) is common. Massive Red Zinc zone mineralizaon typically grades approximately 20 to 30% Zn and approximately 55g/t Ag. Typical examples of the Red Zinc are shown in Figure 24. The full extent of the Red Zinc zone remains to be completely delineated. Mulple Red Zinc zones are noted in the district and one, the Yolanda, is currently being exploited on a small scale by a local mining cooperave. 71 Figure 24. Typical Specimens of Red Zinc showing Composion Variaon Note: Historically, the Red Zinc Manto was known as the Iron oxide Manto. From Hye In Ahn, 2010 72 6.5.2.3 White Zinc Zone The White Zinc zone (smithsonite manto) lies underneath the Red Zinc zone and forms a series of mantos, chimneys, and filled structures. The zone consists of two bodies approximately 100-200 meters across each and up to 70m in thickness. The two bodies of mineralizaon are separated by the Campamento fault which has down-thrown the east body relave to the west body. The thickest secon of the Red Zinc zone directly overlies the White Zinc zone at about the 631700E secon where total zinc mineralizaon is in excess of 200m thick. The mineralizaon follows reacve limestone and dolomite host rocks and karst fill breccia historically known as the “Trinidad” horizon (Haywood and Triple, 1931) in the lower Aurora Formaon. Mineralizaon shows classic karst cave-floor accumulaon and so sediment deformaon. Mineralizaon also shows a very strong structural component occupying steeply dipping faults in the zone and the full extent of the White Zinc manto remains to be determined. Mineralizaon in the White Zinc zone consists primarily of smithsonite with very minor overprinng hemimorphite, and is slightly higher in zinc grade than the Red Zinc zone. There is very lile iron oxide and low levels of lead. Massive White Zinc zone mineralizaon grades approximately 25 to 40% Zn and grades approximately 3g/t Ag. Typical examples of the White Zinc are shown in Figure 25. 73 Figure 25. Typical Specimens of White Zinc showing Textural Variaon. Note: Historically, the White Zinc Manto was known as the Smithsonite Manto. From Hye In Ahn, 2010 74 6.6 DEPOSIT TYPE Data and informaon are taken from Megaw (1988, 1996, and 2009), Sillitoe (2009), Reichert (2009), Borg 2009, Sanchez et al (2009). The Sierra Mojada deposit lies on within three known mineral provinces: The eastern edge of what is termed the Mexican silver belt. The western edge of the MVT Province of NE Mexico and SW U.S. The middle of the northern Mexico CRD (Carbonate Replacement Deposits) belt. The currently accepted model for hypogene mineralizaon in the Sierra Mojada district is a CRD relavely distal from an intrusive source as diagramed in the district schemac showing Figure 26. Figure 26. Schemac Drawing through the Western Poron of the Sierra Mojada Mining District. Note: Schemac drawing through the western poron of the Sierra Mojada mining district showing crical elements of the CRD model as applied to exploraon and development in the district. 75 6.7 SIERRA MOJADA POLYMETALLIC PB-ZN-AG-CU DISTRICT Megaw (1988) classified Sierra Mojada as a CRD type of deposit and, following his classificaon system of CRD deposits in 1996, Sierra Mojada would be considered as a Type III CRD with no direct connecon to an intrusive source. However, Megaw (1996) indicates that the major polymetallic Pb-Zn-Ag-Cu districts in northern Mexico show metal sourcing to be a mixture of basin brines and magmac sources, and suggests that basin dewatering was a magmac thermal driven event, as opposed to a strictly compressional event. Indeed, Sanchez, et al (2009) make a strong argument that Sierra Mojada is part of the NE Mexico MVT province. Abundant direct and circumstanal evidence exists at Sierra Mojada, based on 2011 and 2012 exploraon drilling, that intrusive rocks are present and were likely the thermal drivers of basin brine sourced mineralizaon into a district wide metal zonaon. This evidence includes: The drill hole B12074 collared at the top of Mesa Blanca intersected 58m, from 432 to 490m depth, of felsite sills interleaved with metamorphosed dolomite, intense massive and stockwork silicificaon, and disseminated base metal sulfides. Breccia float in a zone 450m distance from the above drill site with angular chalcopyrite fragments, jasperoid, and mimete (Pb₅(AsO₄)₃Cl) more indicave of a hydrothermal breccia pipe than the local mapped Upper Conglomerate unit. The pipe is located along the main strand of the San Marcos fault. Chargeability highs in a zone trending east from Mesa Blanca to the historic and west towards the Volcan mine area, a distance of 2km. A disnct zone of sulfide mineralizaon surrounding and extending north from the historic Veta Rica mine which includes chalcopyrite, tennante, argenferous galena, arsenopyrite, and sphalerite; implying a formaon temperature >300°C. A center of strong sericite alteraon coincident with the chargeability highs and sulfide mineralizaon around the Veta Rica-San Jose- Deonea historic mine areas. Addional strong sericite alteraon is noted with chalcopyrite in the deepest porons of the San Salvador, Encantada, and Fronteriza workings along the strike of the San Marcos fault. 6.8 SULFIDE MINERALIZATION Megaw (2009) describes the typical distal sulfide mineralizaon in CRD districts, and that observaon is directly applicable to Sierra Mojada. The original sulfide mineralizaon at Sierra Mojada consisted of pyrite, galena, sphalerite, chalcopyrite, arsenopyrite, and tennante; in a gangue of quartz, carbonates, barite, and likely some fluorite with minor celesne. It is believed that up to 30% of the original mineralizaon was gangue minerals at Sierra Mojada. 76 The hypogene sulfide mineralizaon was fed into reacve dolomite horizons and karst features in the Upper Conglomerate and Aurora Formaons by the San Marcos and Northeast fault systems. On a district zoning scale, likely based on an intrusive thermal driver located in the Veta Rica-Mesa Blanca area, the lead manto was deposited furthest from the center, followed by the zinc mantos, with district copper mineralizaon centered in veins and mantos around the historic Veta Rica mine. Silver zonaon tends to begin in the copper zone and extent outward into the lead zones. The original hypogene silver mineralizaon was likely dominated by argenan variees of galena, sphalerite, chalcocite, and tennante; as well as acanthite-argente. These minerals have all been documented by Renaud and Pietrzak (2011a and 2011b). This style of district zoning has been noted CRD districts in Utah, Colorado, New Mexico, and Chihuahua and around numerous cordilleran porphyry districts. Due to the extreme oxidaon of the Sierra Mojada sulfide mineralizaon, only minor remnants of galena, sphalerite, and pyrite have been noted in the zinc mantos, and geochemically immobile cerussite and anglesite are all that remain in the galena mineralizaon in the lead mantos. Silver sulfide minerals are sll present when they have not oxidized to halides Figure 27. Note: Iron-lead silicate mineral crosscut by anastomosing fractures filled with argente (bright fractures) and enclosing fragments of zinc silicate. Renaud and Pietrzak (2011b). Figure 27. Iron-lead Silicate Mineral Crosscut by fracture filling silver. 77 6.9 OXIDE MINERALIZATION Reichert (2009) describes the oxidaon-supergene enrichment sequence on the sulfide-nonsulfide zinc deposits at Mehdi-Abad and Koladahrvazeh in Iran. The non-sulfide zinc mineralizaon in the Sierra Mojada district is directly analogous to the Iranian deposits, while the oxidaon of the silver mineralizaon at Sierra Mojada requires a separate discussion. Figure 28 shows the oxidaon and supergene enrichment (aer Reichert 2009) as it pertains to Sierra Mojada. Note: Development of the Red Zinc and White Zinc zones as a result of oxidaon and supergene enrichment at Sierra Mojada. (Modified from Reichert, 2009). Figure 28. Development of the Red Zinc and White Zinc Zones. 78 Hypogene Pb-Zn-Ag-Cu sulfide mineral mineralizaon in the Sierra Mojada district underwent intense oxidaon, followed by supergene enrichment, followed by a second oxidaon event. The Late Terary to Quaternary events were accelerated by the intense structural development during a period of rapid climate change as the region went from a savanna climate in the Pliocene to the cool-wet climates of the Pleistocene to the hyperaridity of the Present. The non-sulfide zinc mineralizaon at Sierra Mojada would classify as about 70% direct replacement and 30% wallrock replacement, primarily in structures; according to Hitzman (2003). Under oxidizing condions in limestone-dolomite host rocks Sphalerite (ZnS) readily oxidizes to its carbonate equivalent, Smithsonite (ZnCO₃) under high paral pressure of CO₂. Upon relaxaon of the paral pressures of CO₂, Smithsonite alters to hydrozincite (Zn₅(CO₃)₂(OH)₆ prior to the addion of silica leading to the formaon of hemimorphite (Zn₄Si₂O₇(OH)₂·H₂O), the most stable form of nonsulfide zinc. Note that as sphalerite (64% Zn) converts to smithsonite (52% Zn) and finally to hemimorphite (54% Zn) and that the true supergene enrichment is in the conversion of smithsonite to hemimorphite. The abundance of iron in the sphalerite and the presence of iron-sulfur bacteria accelerate the process tremendously. As detailed by Sillitoe (2007) supergene enrichment of silver sulfides is a relavely rare phenomenon. Instead, the silver sulfides of argente- acanthite (Ag₂S) readily oxidize to silver halides (AgCl and AgBr) and nave silver. Argente-acanthite (87% Ag) converts to clorargyrite (75% Ag) and bromargyrite (57% Ag) leading to an “enrichment” by generang more grains of silver halide minerals, with the excess Ag taken up by the nave form (Figure 29). Note: Late stage calcite veins are remobilizing Ag-Br-Cl and is the transporng mechanism for late stage remobilizaon of silver-bearing phases into adjacent dolomite-rich areas. Renaud and Pietrzak (2011b). 79 Figure 29. Late Stage Calcite Veins. 7 EXPLORATION AND DRILLING 7.1 HISTORICAL The mineralizaon in the Sierra Mojada area was discovered in 1879, and early exploraon was conducted by prospecng the outcropping ore. By the 1920’s, diamond drilling was widely used in the district and the subsurface exploraon and development included workings and driing on structures. Underground diamond core and long hole percussion drilling using relavely short, small diameter “B” size holes, was widely used beginning in the 1930s through the 1990’s. Modern exploraon of the Sierra Mojada district began with the Kenneco efforts in the early 1990s which included stragraphic tests by surface diamond drilling and geophysical techniques. Kenneco conducted extensive regional Controlled Source Audio Frequency Magneto Telluric (CSAMT) and Resisvity-Induced Polarizaon (IP) surveys to the north of the Sierra Mojada Range from Palomas Negras to El Oro in the east. These surveys were performed by Zonge Engineering of Tucson. The Mexican government has flown aeromagnec and radiometric surveys for much of northern Mexico, but the data yields only regional structure informaon and a few obvious intrusions. There is not an abundance of igneous rocks, other than deep crystalline (Jurassic to Triassic) basement, known in the area, but subtle signatures of younger diorite to felsite rocks can be detected, including the various mineralized types, that are expected to have high magnec or radiometric suscepbility. Beginning in 1996, Metalline Mining began to collect and compile the historic mine maps, drill core assays to develop new surface and underground mine maps and samples. Channel samples were extensively used to idenfy areas of interest, followed by long hole percussion drilling to extend samples away from old workings, and finally, underground and surface core drilling to extend the sampling further. Surface trenching of bulk metallurgical samples was undertaken in 2010. 7.2 NATURAL CONDITIONS Bedrock exposures in the area are poor to excellent depending on slope and in areas that have been previously mined. As a result, geochemical methods have had mixed success as an exploraon tool. High percent range background values for zinc and lead are common local to zinc-lead deposits, but gradients and vectors that lead to mineral concentraons are just now being recognized. Geochemical rock sampling of targeted stragraphy in conjuncon with structural analysis is the most important exploraon and evaluaon tool. 80 The hyperaridity of the area leads to mass physical dispersion rather than chemical dispersion of metals. Soil development is poor with lile or no organic material and convenonal soils and low level trace element geochemical surveys are not useful in the area. The amount of carbonate and iron-manganese inhibits migraon of metallic ions in this environment. 7.3 SILVER BULL EXPLORATION 2011-2017 Silver Bull’s exploraon program can be broken into two areas: A Regional exploraon effort on exisng licenses and prospects. · A near mine underground channel sampling to highlight areas of immediate potenal resource expansion. 7.3.1 Regional and Prospect Evaluaon Silver Bull Resources has integrated an abundance of informaon, both public and private, in its’ district and regional exploraon efforts in Mexico. From the public side, the Mexican government’s regional geophysical surveys in conjuncon with its regional 1:250,000 scale stream sediment and geologic mapping surveys provide a usable base for prospect evaluaon when used with targeted stragraphy and structural analysis. In addion, Silver Bull has employed SRTM (Shule Radar Topography Mission) and Landsat ASTER images compiled by Sandra Perry of Perry Remote Sensing, Denver, Colorado, to develop remote sensed hydrothermal alteraon models of select target areas. Silver Bull also flew a regional airborne EM (ZTEM) survey in 2011 to act as a base for regional license exploraon. In addion, Silver Bull engaged in a program of detailed structural analysis of the Sierra Mojada district as well as a detailed me, lithologic, and biostragraphic compilaon of the project area during 2014. Extensive use of petrography has aided considerably in the interpretaon and paragenec sequencing of mineralizaon. The use of outside specialists in this regard has been parcularly useful in all aspects of the program. Table 7 outlines the prospects of interest to Silver Bull while Figures 32 shows the locaons of the Sierra Mojada license with the associated license and prospect areas outlined in Table 7. 81 7.4 SOUTH32 JOINT VENTURE 2018-2019 ON June 4, 2018 announced it had signed a deal with South32 Limited granng it a 4-year opon to form a 70/30 joint venture. Under the opon, South32 had to contribute a minimum exploraon funding of US$10 million (“Inial Funding”) during a 4-year opon period with minimum aggregate exploraon funding of US$3 million, US$6 million and US$8 million to be made by the end of years 1, 2 and 3 of the opon periods respecvely. If South32 exercised its opon to subscribe for 70% of the shares of Mexican subsidiary Minera Metalin S.A. De C.V. (“Metalin”), South32 would contribute an addional $US100 million to Metalin for Project funding From June 2019 to September 2019 mapping, sampling, and then drilling where conducted exploring the wider area outside of the main deposit at Sierra Mojada. A total of 6,500m was drilled on prospects outside of the main deposit at Sierra Mojada. Although some narrow mineralized intercepts were hit, it was not deemed significant. A summary of the results from this drilling is shown in the table below. Locaons of the drillholes are shown in Figures 30 & 31. Table 6. Summary of the main drilling conducted under the South32 Joint Venture. 82 Figure 30. Drilling 950m east of the main deposit, tesng mineralizaon at depth. Figure 31. Regional exploraon drilling locaons and results along the Sierra Mojada trend. On 1 September 2022, South32 terminated the opon agreement with Silver Bull cing an inability to access the property due to an ongoing illegal blockade that started on 30 September 2019 by a group of locals demanding early payment of a producon royalty. On one of the licences in that make up the licence package at Sierra Mojada. The illegal blockade remains in place at the me of wring this report. 83 Table 7.

Regional Exploraon Prospects in the immediate Sierra Mojada area. 85 7.4.1 Underground Channel Samples Channel sampling has been a significant part of the underground exploraon effort at Sierra Mojada. Channel samples are collected from the walls (“ribs”) of underground workings by a supervising geologist who has selected the channel sample locaon, painted the posion of the sample on the mine wall, and wrote the sample number on a sample sack that was suspended from a nail at the sample point. The sampler marks the approximate sample locaon on a mine map and reports the sample number of each sample on a daily sampling report. At the sample locaon, sampling crews spread a drop cloth, clean the face, and cut a sample about 2 cm deep and 10 to 20 cm wide. The sample was transferred to a large plasc sample sack and about 5 to 6 kilograms of sample are transported from the mine to the sample preparaon area. Samples are typically 1-2 meters in length. Sample locaon, length and orientaon are subsequently determined by the surveyor using tape and compass surveying ed to nearby pads located by first order surveying. Aer sampling, the sample locaons are surveyed and entered into the database. To the best extent possible, a representave and proporonate volume of material is collected in each sample of the composite vein, fault, breccia and wallrock material. Sample density for channels is considerably greater than for diamond core at 2 to 20 m spacing. There are approximately 13,000 channel samples in the site-wide sample database covering an area of 180 hectares. 9027 channel samples were used in modeling the resource. Approximately 90% of all channel samples were collected prior to Silver Bull’s involvement in the project and about five percent of the samples have been re-sampled for verificaon and approximately 70% of the locaons have been verified. There are now 9027 usable channel samples in the database with associated QA/QC and surveyed locaons. These have been useful in mapping out extensions to the main deposit. 7.5 EXPLORATION CONCLUSIONS Silver Bull Resources has integrated an abundance of informaon at the deposit scale and district scale for its exploraon efforts in Mexico. The Mexican government’s regional geophysical surveys in conjuncon with its regional 1:250,000 scale stream sediment and geologic mapping surveys provide a usable base for prospect evaluaon when combined with targeted stragraphy and structural analysis. A summary of the findings to date include: · Petrography has aided considerably in the interpretaon and paragenec sequencing of mineralizaon. 86 · A detailed structural analysis of the Sierra Mojada district has shown the likely “plumbing system” for the mineralizaon in the area and delineated other areas with similar potenal. · Magnec and Electro-magnec geophysical surveys have aided greatly in helping delineate areas of high interest. · Geological mapping and sampling in areas with historical workings show there is a favourable rock unit to host mineralizaon and also put constraints on the ming of mineralizaon. · Alteraon mapping coupled with the style of mineralizaon seen in the area suggests yet to be found buried intrusive rocks are the likely genesis of the mineralizaon. 7.6 DRILLING Drilling is updated from SRK (2012), JDS (2013) and Tuun & AFK (2015). Throughout its history, the Sierra Mojada deposit has been drilled extensively by surface diamond core, underground diamond core, surface reverse circulaon and underground long hole percussion drilling. There are now 5,382 drill holes in the database of which only 3,823 are suitable for resource calculaons. Tables 8 and 9 document the extensive history of the drilling programs to the present. No new drilling results have been included since the JDS 2013 report for this resource esmaon. The following text is taken from Tuun & AFK (2015). 7.7 HISTORIC DRILLING PRE-1999 Numerous drill holes exist in the Sierra Mojada project area for which locaons and or assays are missing and for which few records exist. One drill hole though, B6, completed in 1900, is a 150 meter surface drill hole which has consistently been included in resource calculaons. Kenneco Exploraon drilled nine core holes in the area in 1995 (SM1 –SM9), for 3403.85 m. Only 2 of the holes are within the district and those did not carry significant assays. The local Norteños drilled 873 long holes between 1930 and 1950 for 22,435 m. These holes were drilled from numerous underground staons in radiang fan patterns. The drilling was concentrated on four separate areas along the trend of silver mineralizaon. Within these four areas, underground stations are typically spaced 20 m apart with average hole depths 25 m resulting in very dense drilling. Areal coverage of these long holes is approximately 9 hectares, and none of these drill holes is suitable for resource calculaons. Many long-hole locaons are recorded, with assays, but verificaon is not possible. 87 7.8 METALLINE MINING CORPORATION (MMC) MMC purchased all of the available historic data from Peñoles in 2000, much of which is sll in usable condion. This included early 1900s underground maps, drill hole folio dating from 1930 to 1950 and a few late 1980s reports. The drill hole folio included the 873 long holes. 7.8.1 MMC Drilling Campaign of 1999 Metalline drilled twenty-four holes from surface (R991 – R999) using reverse circulaon for a total of 6,628 m. This drilling covers 28 hectares and intercepts the Red Zinc and Shallow Silver Zones. Approximately half of the holes were drilled vertically and the remaining holes were angled with inclinaons ranging from vertical to 54°. These drill holes have been used in resource calculaons since 2011. 7.8.2 MMC and North Limited Campaign of 2000 MMC entered a joint venture with North Limited of Australia in 2000. North drilled a string of 26 reverse circulaon holes (NSM1 – NSM27) over a linear distance of approximately 3.5 km down the long axis of the known Red Zinc Manto for 6,783 m. All holes were drilled vercally. These drill holes have been used since 2011 in project resource calculaons. 7.8.3 MMC Underground Drilling Campaign of 2001 MMC drilled 73 underground long holes for 1,068 meters in 2001 (L632500S45- L631855NE15). These holes were drilled from several underground staons in radiang fan paerns. This drilling is located at the western extent of the Red Zinc Manto. For reasons related to sample quality, these holes were not used for resource calculaons unl verificaon in 2012 by Silver Bull Resources. 88 Table 8.

Two different exploraon teams from Peñoles spearheaded the drilling acvies. One team focused on the eastern end of the deposit targeng the Red Zinc Manto in 2002 and 2003. This consisted of both diamond core and long hole drilling from underground and diamond core drilling from surface. The second team drilled core holes from surface targeng SSZ on at the western end of the property. The joint venture dissolved in late 2003. 7.9.1 Surface Diamond Core The joint venture completed thirty-nine diamond core holes drilled from the surface for 11,830 m total. On the eastern end of the property 34 diamond core holes, generally labeled the E900 to E1200 series, were drilled on fences spaced 200 m apart east of the Fronteriza mine toward the Oriental mine, a distance of 1 km. The holes were spaced 50 to 100 m in a north-south direcon along the fences. The Peñoles program at the western end of the property followed up the North Limited drilling in the vicinity of the San Antonio mine, 2 km west, which confirmed and extended the silver mineralizaon. Five core holes were drilled from surface for about 1,300 m. The drill hole locaons are irregularly spaced, and cover an area of approximately 7 hectares. The drill hole series are believed to be the W200 to W300 series, not to be confused with underground long holes with similar numbers. 7.9.2 Underground Diamond Core Thirty-seven diamond core holes were drilled from underground for 2,557 m. These holes were drilled from several underground drilling staons in radiang fan paerns and are of the A0 to M6 series. Drilling staons are typically spaced 50 to 100 m apart in an irregular paern. This drilling covered approximately 7 hectares, mostly over the Red Zinc mineralizaon. 7.9.3 Underground Long Hole Primarily in 2002, 685 underground long holes were drilled for 10,729 m. These are generally labeled the E100 to E600 and W400 to W600 series. Typically, these holes are drilled from several underground staons in radiang fan paerns. Spacing of the underground staons is typically less than 20 m and hole lengths average 13 m resulng in very dense drilling. These holes intercept much of the Red Zinc Manto and SSZ mineralizaon east of Easng 630,700. The Silver Bull 2012-2013 twinning program has verified the reliability of the majority of these drill holes and the data was included in the JDS 2013 resource calculaon. 91 7.10 MMC CAMPAIGN OF 2004 TO 2009 Upon the terminaon of the Peñoles joint venture, Metalline resumed district exploraon with a very aggressive program of surface and underground core, underground long hole, and surface RC drilling primarily targeng the zinc resource. 7.10.1 Surface Diamond Core MMC drilled 103 “N” size diamond drill holes from surface for 15,231 m from 2006 – 2009 (D1080729 – D9090818 and B09001 – B09013). The surface drilling was completed along fences oriented north-south with 100 m spacing and drill hole spacing varying from 50 m to 200 m. The main concentration of drilling covers approximately 20 hectares intercepting the SSZ just west of the Red Zinc Manto. Vertical dip is commonly used, however, and due to location restrictions, some holes are angled, drilled with dips up to 60 degrees. MMC updated the surface drilling practices employed during the MMC and Peñoles drilling campaign of 2002 to 2003 and largely mitigated the core and sample recovery issues by employing sophisticated mud and bit selecon, and employing a well-known contractor, Major Drilling de Mexico. 7.10.2 Underground Diamond Core MMC drilled 650 underground diamond drill holes for 65,052 m (D01040124 – D9080807) in the 2004 – 2008 periods. These holes were drilled from several underground drilling staons in radiang fan paerns. Drilling staons are typically spaced 50 to 100 m apart in an irregular paern. This drilling covers approximately 52 hectares intercepng most of the known Red Zinc Manto and Shallow Silver Zone mineralizaon east of Easng 631,200. 7.10.3 Surface Reverse Circulaon MMC drilled eight reverse circulaon holes (R060707 – R060926) from the surface for 2,938 meters in 2006. These were water well and condemnaon holes drilled in an irregular and widely spaced paern tesng areas east and north of the underground workings. Of these eight holes, only R060926 intercepted the known silver mineralizaon. For reasons related to sample quality, these holes were not used for grade interpolaon. 92 7.10.4 Underground Long Hole Twenty-two hundred fiy three underground long holes were drilled by Metalline Mining in 2004-2009 for 31,272 m. The drill hole series are variously numbered, typically prefixed with an “L”. These holes were typically drilled from several underground staons in radiang fan paerns. Spacing of the underground staons was less than 50 meters and hole lengths average 17 meters, resulng in very dense drilling. The drill holes intercept much of the Red Zinc manto and Shallow Silver mineralizaon east of Easng 630,700. 7.11 MMC CAMPAIGN OF 2010 7.11.1 Surface Diamond Core In 2010, MMC completed 101 surface HQ/NQ drill holes (B10001 – B10099) for 12,512 m property wide. Drilling was undertaken using three Metalline-owned diamond drill rigs and three drill rigs operated by drilling contractors. Contract drilling was performed by two companies. Baja Drilling S.A. de C.V. used a skid- mounted Longyear 48 machine to complete three holes. However, most contract drilling was performed by Landdrill Internaonal México S.A. de C.V. with a skid-mounted HTM 225 machine. The drilling was completed along fences oriented North-South with drill hole spacing of 40 to 200 m. The principal concentraon of drilling covers an area of approximately 40 ha, and intercepts the SSZ just west of the Red Zinc Manto. Vercal inclinaons were used in the majority of holes with some holes angled up to 60°. 7.11.2 Surface Reverse Circulaon In 2010, MMC also drilled 48 reverse circulaon holes (R0001 –R0048) for 6,879 m. These were principally in-fill holes between core locaons. Forty-eight RC pre- collar holes were drilled. Thirty-one of these holes were completed by core drilling. In areas of deep quaternary cover RC pre- collar holes were drilled either close to the base of QAL contact or close to the Upper Conglomerate lower contact. RC drilling was performed using a Th-100 Tandem truck mounted 7.15.4 Sampling Security during Core Cung drill used by contractor Layne de Mexico S.A. de C.V. and a smaller truck mounted CDR drill, owned and operated by Metalline. 93 7.12 SILVER BULL CORE DRILLING CAMPAIGNS OF 2011-2013 Procedures described for Silver Bull are modified and updated from Nilsson 2011. Beginning in April of 2011, Silver Bull Resources assumed full control of the Si7.15.4 Sampling Security during Core Cung erra Mojada project and revamped all drilling, core handling, logging, and assay procedures. Drilling included surface and two underground campaigns. As part of their due diligence review of the Sierra Mojada project, Silver Bull drilled 33 RC/Core holes (R100001 – R10034) for 5,927.85 m. 7.12.1 Surface Diamond Core Major Drilling de Mexico was the contractor employed to complete 186 HQ/NQ surface core holes in 2011 (B1101 – B11185) and 80 holes in early 2012 (B120001 – B12083) for a total of 52,347.1 m. Major employed a UDR 650 drill rig with a reversible head and compressor, which allowed RC drilling to pre-determined depths, switching to HQ core when entering mineralized stragraphy. 7.12.2 Underground Diamond Core In early 2012, Silver Bull turned its aenon toward underground drilling in the district and completed two underground drilling campaigns by year’s end. The first was in early 2012 when Silver Bull completed 13 drill holes in the Parreña Tunnel for 4,055 m of core. The program provided significant informaon regarding local structures and stragraphy but did not materially add to the resource. The Parreña Tunnel remains a significant exploraon target but will require a significant amount of rehabilitaon of the underground workings. The second underground drilling program of 2012 was the long hole twinning program recommended by SRK in their 2012 resource statement. This program commenced in July 2012 and terminated on the Christmas break in mid-December 2012. The program targeted 105 drill holes for twinning and exploratory for 3,670.75 m of drilling in the Shallow Silver Zone, and 88 drill holes for 3,467.46 m in the Red and White Zinc mantos of the Base Metal Manto zone. The layout of the program is shown in Figure 33. Note that mulple holes were drilled from one setup or drill staon. A total of 207 termite holes were drilled; one (T12008) was not included in the resource esmaon due to very poor recovery. The termite drill program is summarized in Table 10. 94 Table 10.

Layout of the 2012-2013 Drilling Program 96 The drilling was accomplished by Silver Bull Resources owned “termite” drills, which are small, hydraulic-electric core drills that are easily manoeuvred underground. The drill produces a “BQ” size drill hole and is capable of up-hole drilling. The maximum length of a drill hole is about 70 m, depending on ground condions. Core recovery for the enre program was excellent considering the structural complexity of the deposit. Figure 34 demonstrates a typical underground drill staon set-up. Figure 34. Typical Set-Up of the Termite Drill during the Long Hole Twin Program, 2012-2013 7.13 SULPHIDE DRILLING 2017 An underground geological mapping and connuous underground channel sampling program in July and August 2017 idenfied a series of east- west trending high angle structure hosng sulphide mineralizaon below the oxide zone of mineralizaon. A 2,000 meter underground drill campaign targeted this area with considerable success. However due to the very different metallurgical process required to beneficiate the sulphide ore, none of this drilling from this campaign is included in the esmaon of the oxide resource outlined in this report. 97 7.14 SILVER BULL CORE DRILLING AND SAMPLING PROCEDURES Silver Bull Resources employs state of the art exploraon procedures in all of its work at Sierra Mojada. All data is managed in Microso Excel or Access, with the Excel files imported directly into Geovia Soware’s GEM’s® for 3D modeling. Data is also transformed to a visual format in MapInfo. All survey data is imported into AutoCAD, and the informaon required for the resource esmaon is transferred to GEMS. The following procedures apply equally to the surface core drilling programs as well as the underground core drilling programs. 7.14.1 Collar and Downhole Surveys Drill holes were laid out on an approximate 100 m x 50 m grid. Drillhole locaons were marked in the field by the company surveyor or geologist. Drill pads were then prepared and final collar locaons were marked by the surveyor. When collar locaons were located on gravel sites a concrete pad with iron-rod aachment points were constructed. For pads on bedrock, jacklegs were used to create anchor points for the drill rigs. Drill pads varied in size from 5 m x 5 m in size to 10 m x 20 m in dimension, depending on the type and number of holes planned from that site. Aer drill holes were completed, steel pipes were inserted to mark the locaons and concrete pads with drill hole numbers were poured to hold the pipes in place. The final drill hole locaons were surveyed by the company surveyor using a total staon survey instrument. Geologists approved the final collar surveys prior to entry into the database. All drill holes were down hole surveyed using Reflex survey instruments. Surveys were done using an EZ-Shot single survey instrument. Some holes were surveyed with a Reflex EZ-Trac instrument. All Reflex results were recorded at the me of the survey. Surveys were performed by the driller, with a company representave present, either a geologist or drill supervisor. 7.15 Core Drilling, Handling, and Transportaon All coring by contractor was done with HQ or HQ3 core size, unless reduced to NQ size for operaonal reasons. Some holes with quaternary cover were predrilled using a tricone bit, drilling down to a level close to the base of the cover or solid ground, this varied from 3 – 30 m. 98 Core was removed from wire line core barrels at the drill rig and placed into waxed fiberboard core boxes. Core boxes were 60 cm in length with 4, 5 or 6 divisions depending on core size. The driller’s recorded end of run depth, drilled interval and core recovery on blocks placed in core boxes. Where possible drillers also inserted an addional block indicang where the “no recovery zones” were located’ and if the “no recovery zones” were due to a void (old working or open space). Hole numbers and core box numbers were wrien on the core boxes and lids. Core boxes were then ed up and at the end of the shi core boxes were transported by truck to the core logging facility. Core transportaon from drill rig to the core logging facility was the responsibility of the driller. 7.15.1 Core Logging Procedures When the core boxes were received at the core logging facility, the core was placed on logging tables where the core was cleaned to remove drilling muds and addives. A minimal amount of cleaning was performed on clay rich and poorly consolidated intervals. The core was reconstructed to ensure that the core was placed in the boxes correctly and so that there was structural connuity for logging and sampling. Aer reconstrucon, the cut line for core cung/spling was marked on the core. As far as possible, this line was placed perpendicular to the main structural orientaon – as indicated by responsible logging geologist. Core was also marked with dashed lines on the non-sample side to indicate that it should remain in the box. All core was photographed aer cleaning and orientaon, generally before the recovery and geotechnical logging. Core was photographed using an indoor, special lighng and fixed camera. All photographs included hole name, box number, box start and end depths and a scale bar. Photographs were downloaded onto a computer at the logging facility for review by geologist before sampling. This was done to ensure photos were of good quality with no errors. Digital core photos were renumbered by hole and box number and placed into drill hole specific folders. Recovery and geotechnical logging, including RQD was then performed by trained personnel. Any doubts or quesons on recovery and core orientaon were reviewed by the responsible core logging geologist with all recoveries being compared to those indicated by the driller. In rare cases of discrepancy or core box errors that could not be corrected by the geologist, the responsible driller(s) were required to correct the problem. To assist with logging, down-hole depths were marked every meter. 99 Recovery and geotechnical informaon was recorded on a run-by-run (block-to-block) basis. Informaon was entered into a spreadsheet. Recovery was variable with “no recovery intervals” resulng from a variety of causes. Limestone rocks at Sierra Mojada contain many natural openings such as cavies and karst features, and in most areas of the Shallow Silver Zone, old workings are a common feature and these were represented by “no recovery intervals” as well as zones with backfill, which are harder to disnguish; and in clay, poorly consolidated karst breccia or rubble zones. In addion, the drill core has NitonTM thermal XRF measurements taken approximately every 20 cm as a guide to the beginning and ending of silver mineralizaon, which can be difficult to discern with the naked eye. Aer inspecon, mark-up, geotechnical logging, and photography, geological core-logging was performed. Core logging formats evolved considerably when Silver Bull assumed control of the project. Silver Bull employs a combinaon of inial manual graphic logging followed by digital logging and subsequent data entry. Lithology types, alteraon, mineralizaon and structural features were recorded on a 1:100 scale. 7.15.2 Core Sampling Core was marked for sampling by the geologist as part of the core logging procedure. Sample limits were marked on the core as well as the side of the core box. Sample intervals were also noted on cut sheets. Intervals and sample recoveries were entered directly into a spreadsheet, with cut sheets subsequently printed for core sawing. Samples were assigned a sample numbers based on hole number and a three or five digit sequenal number; “no sample intervals” were also assigned a sample number and were included on the cut sheets. Quality control samples consisng of blanks, core duplicates, and pulp standards were inserted in the sequenal sample number sequence. Each sample number had the appropriate sample interval or control sample indicated on the cut sheet as well as the sample acon to be taken for intervals of no recovery or contaminated material. In addion to marking of samples for assay intervals, bulk density samples were selected during the logging process. The density samples were approximately 10 cm in length with density measurements taken before the core is split with the core cuer. Inially total of 3440 bulk density sample measurements were compiled by Silver Bull incorporang samples measured on site by the pycnometer method and verified by ALS, and by the Archimedes method and verified by SGS in Durango, Mexico. An addional 1,895 pycnometer density samples were taken in 2013 and 2014. 100 Aer logging and sample marking of the hole was completed, the core was split in half using a core cuer. Once the core was cut in half, specially trained samplers were used to sample the core. Based on the marking procedures, core was systemacally sampled from the same side of the core, which has helped to reduce the possibility of sample bias. The samples were placed in numbered sample bags, in which flagging tape with the sample number was also placed in the bag and barcoded. Bagged samples were placed in numbered sacks with the content of each sack recorded for shipment to the external laboratory. Sample sacks were placed in a locked storage area prior to shipment. Sample storage and shipments were controlled by Silver Bull’s QA/QC manager. 7.12.3 Data Entry All logging and sampling data are entered into spreadsheets. Density, recovery, and geotechnical data were entered into master spreadsheets, from which individual drill hole data could be extracted. Data are entered by the logging geologists and then rechecked by a data verifier. This procedure was implemented to allow geologists to concentrate more me on geologic logging and sampling. Sample data were also entered into drill hole based spreadsheets. These were used to prepare cut- sheets for sampling. This data was prepared by the logging geologist. Geological data were entered into the drill hole based spreadsheets. These data were prepared by the core logging geologist. Manual core logging with subsequent data entry into the Excel spreadsheet was implemented, with each of the logging geologists responsible for entering the data and passing the database to the database manager who reviewed the entries for errors and database coding compability. Once the data had been checked, the data were entered into the master database controlled by the database manager. 7.15.4 Sampling Security during Core Cung Once the samples were taken from the core, they were bagged, organized and labeled by one specific person, signed off, and then kept under lock and key unl shipped for assaying to ensure no tampering had taken place. Aer logging and sampling, the core boxes containing the split core were transported to the core storage facility, a locked, fenced, roofed structure. The core boxes were stored on commercially purchased core racks, with locaon idenfied on layout plans. The storage facilies were part of the security watchman’s responsibilies, who are present 24 hours on site. The company has four secure core storage facilies on site. 101 All core and samples are retained on Silver Bull’s property, except for samples sent to external laboratories for assaying. Access to the property is restricted by company security personnel and chain gated entries to the property. The core logging area always has company personnel present, in the form of core shed workers or company security personnel. Coarse reject samples are stored in covered 200-litre steel drums in an outdoor storage area adjacent to the core shed. Sample pulps, grouped into boxes containing between 50 and 100 envelopes, are stored in the locked storage areas. 102 8 SAMPLE PREPARATION, ANALYSES, AND SECURITY The Authors note that no new data is being added to the resource esmaon since the resource report by Tuun and AFK (2015) and there have been no changes to the sample preparaon, analyses and security procedures ulized at the Sierra Mojada project, all of which have been described in detail in previous technical reports. That informaon is reproduced in the following secons. 8.1 SAMPLE PREPARATION Prior to November 2003, all samples were shipped directly to ALS Chemex (ALS) for sample preparaon and assay. Aer November 2003, samples were prepared to the pulp stage on site by MMC personnel. In 2007, MMC updated its laboratory equipment and sample preparaon procedures following recommendaons made by ALS. In 2010, Silver Bull abandoned the on-site sample preparaon and began shipping samples to ALS for preparaon and assay. (SRK 2012) JDS personnel were present for the April 2010 due diligence site (Dome Ventures-MMC merger) and noted that there was a significant backlog of unprocessed samples stored at the site. Part of this was due to the inefficiencies of the onsite lab, and part a lack of funding. JDS recommended that the onsite lab be closed to eliminate any potenal concerns regarding the QA/QC and assay validity. With the closure of the onsite lab, efforts were made to ship them to a reliable and ISO-cerfied off site lab. A total of about 7,000 samples were shipped between August 2011 and April 2012 to ALS-Chemex Chihuahua. Many of the assay results were incorporated into the Nilsson and SRK resource esmates. JDS was present for the closure, cleanup, and chemicals disposal of the onsite lab. Since that me, all sample preparaon has been standard core-cung, tagging and bagging for shipment offsite to the ALS-Chemex facility in Chihuahua. From there, pulps were shipped to the ALS-Global lab in Hermosillo for assaying. JDS has received copies of the assay files direct from ALS-Global labs since the introducon of the change, along with copies of the shipping files from Silver Bull site staff. (JDS 2013) 103 8.1.1 MMC-SILVER BULL SAMPLE PREPARATION PROCEDURES (2010-PRESENT) Drill core is delivered by the drill contractor to the logging facility. The movement of the core, once delivered at the logging facility, is designed such that it is always in an easterly direcon as it goes through each phase of the logging and sampling process, entering on the west side of the facility and leaving on the east side of the facility towards the sample storage area. Inially, boxes are laid out in order on the logging tables by company staff. The meterage blocks inserted by the drill contractor are checked to ensure there are no errors. Drill core recovery between each of these blocks is calculated and recorded. Subsequently, the core is logged by a geologist who also marks the intervals to be sampled and prints out a "Sample Print Sheet", indicang sample numbers and the sample numbers for the QA/QC sample inseron. At this point, Niton® readings are taken in each sample interval and recorded. Once logged, and with the sample intervals marked, the core boxes are then taken to the photograph, density, and bar coding room. Here, each core box is photographed in a staged facility that ensures idencal lighng for each photograph. Density samples are taken (the samples to be taken are indicated by the geologist) and the bar codes for each sample are then printed. Following the photography, the boxes are carried and stacked, ready for the core to be cut by a rock saw. Half core samples are taken according to the sample intervals marked by the geologist and, when required (as indicated by the QA/QC program), quarter core field duplicates are also cut. Samples for assay are placed in thick plasc sample bags with the sample number wrien on them and a strip of flagging with the sample number wrien on it is inserted into the sample bag. The bags are then stapled firmly shut. The samples are then placed into rice sacks, eight samples per sack. From the start of the year unl June 30, 2011, samples were shipped two or three mes a week once one tonne of sample material had accumulated. The shipment was done with company personnel and a company vehicle. As of July 1, 2011, sample shipment to the ALS preparaon facility in Chihuahua has been subcontracted. The subcontractor is a company that Silver Bull has used for a number of years for other services and is regarded as trustworthy and reliable. Shipments are programmed weekly. Once received by ALS, they check the shipment and confirm via e-mail whether the samples shipped coincide with what is registered on the shipment form and analysis submial. (SRK 2012) 104 8.1.2 MMC SAMPLE PREPARATION PROCEDURES (2007-2010) From 2007 to 2010, sample preparaon was done at the Sierra Mojada property by MMC personnel. Samples were first dried in a clean drying pan. Aer the samples were thoroughly dried, the pan and samples were transferred to the on-site preparaon facility. The samples passed through a Rhino crusher and then a secondary crusher resulng in material that has been crushed to greater than 70 % passing -10 mesh (-2 mm). The crushed samples were split in a Jones splier mulple mes to generate a 250 to 300 g crushed sub-samples. The crushed sub-samples were then transferred to a puck mill and milled for three minutes to aain a size specificaon of greater than 95 % passing a -150 mesh screen. The pulverized material was passed through a riffle splier to generate two pulp sub-samples (one for analysis and one for reference). The pulp sub-samples were transferred to individual sample bags. The methods ulised by MMC were standard and adequate for generang assay data for use in resource esmaon. (SRK 2012) 8.1.3 MMC SAMPLE PREPARATION PROCEDURES (2003-2007) All samples were weighed and their weight was recorded before processing. The enre samples were then crushed to nominal ¾-inch (in) sized samples using a Fraser & Chalmers jaw crusher. The crusher was cleaned aer each sample using compressed air. Once first stage crushing was completed, the samples were then crushed to nominal ¼-in sized samples using a Roskamp rolls crusher. The rolls crusher was also cleaned with compressed air aer each sample. All quality control was visual at both crushing stages and no tesng for screen sizing was done at either stage. Aer the second crushing stage, the nominal ¼-in sample was split through a Jones type splier to approximately 500 g, and placed in an aluminum pan, to be taken to the drying oven. Each pan was well labelled, with the contained sample number recorded on masking tape, aached to the pan. Drying was conducted in a block building which has two propane space heaters, manufactured by Desa, Inc. The samples were placed upon drying racks, sll in the aluminum pans, and a heater was acvated. Once dry, the pans and contained samples were returned to the sample preparaon area for pulverizing. Pulverizing was conducted upon the ¼-in samples using one of four Bico disc pulverisers. The 500 g sample was pulverized to nominal 80 mesh, with visual and tacle inspecon performed upon each sample aer pulverizing to ensure that the nominal 80 mesh size was achieved. No screen size tesng is done upon the pulverized samples on a regular basis. The pulverisers were cleaned with compressed air aer each sample was processed. Once pulverising was completed, each 500 g sample was split into two sub-samples, with a maximum of 200 g kept for each sub sample. These two sub-samples were packaged in Kra type envelopes; one 200 g sample was sent to the shipping area to be boxed and prepared for shipping to the ALS laboratory in Vancouver, BC, Canada. The remaining 200 g sample was stored in archive storage, as a reserve sample, should more analysis be required. All pulps were labelled with the sample number, which has all drill hole and interval data included, as well as the date the sample was drilled. 105 The sample preparaon methods used from 2003 to 2007 are adequate for generang assay data for use in resource esmaon. (SRK 2012) Pincock, Allen Holt had reviewed the process and made several recommendaons to improve reliability which ulmately led to their S-K 1300 compliant Technical Resource Report issued in January 2010. (JDS 2013) 8.1.4 MMC SAMPLE PREPARATION PROCEDURES (PRE-2003) Prior to 2003, all sample preparaons were carried out by ALS laboratory using the following procedures: Coarse crushing of rock chip and drill samples to 70 % nominal -6 mm was used if the material received was too coarse for introducon into the pulverizing mill, and as a preliminary step before fine crushing of larger samples. Fine crushing of rock chip and drill samples to 70 % -2 mm or beer. Samples were split sample using a riffle splier. The split sample was pulverized using a “flying disk” or “ring and puck” style grinding mills. Unless otherwise indicated, all pulverizing material was at least 85 % pulverized to 75 micron (200 mesh) or beer. These sample preparaon procedures are adequate for generang assay data to be used in resource esmaon. (SRK 2012) 106 8.2 ANALYSES (Aer Tuun & AFK 2015, JDS 2013 & SRK 2012) 8.2.1 QUALITY ASSURANCE/QUALITY CONTROL (QA/QC) 8.2.1.1 Historical QA/QC Procedures PAH reviewed the QA/QC procedures implemented throughout the life of the project and concluded that they were insufficient relave to current industry standards of pracce. As a result of these inadequate procedures, PAH was not able to classify its January 2010 resource esmate for Sierra Mojada as anything higher than an inferred mineral resource. To resolve this issue, MMC and PAH developed and executed a re-sampling and assaying program to esmate the type, frequency, and magnitude of assay sample errors in the historical drill hole database for the Sierra Mojada project. This plan was meant as a substute of the QA/QC program that would resolve PAH’s doubts about the validity of the Sierra Mojada assay data. Based on the execuon of the program and a detailed review of the results, PAH concluded that the drill hole assay data for channel and core samples used in its January 2010 resource esmate were of sufficient quality to support measured and indicated resources. As a caveat, PAH notes that converng inferred resources to measured and indicated is conngent upon other factors not related to data quality (McMahon, 2010). SRK has reviewed the results of the addional sampling program carried out by PAH and concurs with their conclusions. In 2010 a QA/QC program of cerfied standards, blanks and duplicates were instuted to monitor the integrity of all drilling assay results. Two sets of QA/QC procedures were used by Metalline since the me of a QA/QC review performed by PAH (McMahon, 2010) on pre-March 2008 drill hole assay data: The first set of QAQC procedures was used for the submission of pulp samples for analysis by a cerfied laboratory. These pulps had previously been prepared and analyzed by the Metalline on-site laboratory facility as part of a pre-selecon process. All samples for 2008 and 2009 drill campaigns and all 2010 drilled prior to August 2010 followed these procedures; and The second set of QAQC procedures applies to samples sent directly to ALS for sample preparaon and analysis. This procedure has been in place since August 2010 and includes drill holes submied since this me. (SRK 2012) 107 8.2.1.2 Pulp Submissions QA/QC Procedures Aer sample preparaon all samples selected for cerfied laboratory analysis were located and placed in boxes ready for shipment. The same pulp envelope used for the original analysis was selected for submission to the external laboratory. Each sample box contained between 60 and 120 pulp samples, including control samples. The QA/QC control samples submied in each box consisted of: A minimum of three standard samples were submied, normally at least one of each of the three cerfied standards prepared for Metalline Mining by CDN Laboratories; At least one blank pulp sample and oen two; At least one, and generally two, field duplicate samples (¼ or ½ core samples) prepared but not analyzed by Metalline onsite during 2010. In general ¼ core samples were submied so as to leave witness core in the core box, however in broken zones the complete remaining half core was selected for submission; and At least one and generally two pulp duplicate samples, with splits made from the original pulp sample to be selected within the same box. (SRK 2012) 8.2.1.3 Core Submissions QA/QC Procedures Control samples were inserted approximately every 10 core samples. In addion, aer every 25 core samples the following addional samples were inserted: a minimum of one cerfied standard is included; a minimum of one field duplicate sample is included; and normally one blank sample is included and occasionally blanks are preferenally inserted in a mineralized sequence outside of the normal 25 sample range. In November 2010, the system was modified slightly to ensure that controls samples were inserted at a standard interval of every 10 sample numbers. (SRK 2012) This procedure is sll in place for any future drilling. 8.2.1.4 Reference Standards The Author (Reeves) noted that Metalline/Silver Bull staff inserted cerfied reference standards as a quality check on the laboratory accuracy. The reference standards were prepared by CDN Resource Laboratories Ltd. which specializes in preparing site specific cerfied standards. The three standards prepared are idenfied in the database as K10001, K10002 and K10003. 108 Reference Standard K10001 A total of 245 standards were inserted into the sample stream and only one was reported below the reference 2SDs. All samples were within three SDs of the reference mean (Figure 35). (JDS 2013) Reference Standard K10002 A total of 223 samples of reference standard K10002 were used, with 9 samples outside of the standards report 2SD limits (Figure 36). Two that were just above 3SD will require follow-up checks by Silver Bull. The ALS-Chemex sample mean is also slightly higher than the reference mean by about 0.8 g/t Ag, but is not considered to have an impact on the resource esmaon. (JDS 2013) Reference Standard K10003 A total of 199 samples of reference standard K10003 inserted into the sample stream. It is clear from Figure 37 that the ALS-Chemex mean is about 3.5 g/t higher than the reference standard mean. Even with this offset, all but three samples fell within 3SD. Silver Bull Resources will need to follow up on the cause of the lab bias, which is quite consistent in this standard. (JDS 2013) 109 Figure 35. Graphical Performance of Standard K10001 Figure 36. Graphical Representaon of Standard K10002 110 Figure 37. Graphical Representaon of Standard K10003 8.2.1.5 Blanks Controls Blank samples were used to check for laboratory sample preparaon issues and accuracy. These samples consisted of material that contained low but not below detecon limits grades of elements to be analyzed. Four types of blank sample material were used by Metalline: Pulverized blank material obtained from either rock samples or crushed material from the Peñoles Dolomita mining operaon. Pulverized blank samples were prepared and analyzed at the Metalline laboratory to confirm their blank nature; Blank core samples were either ¼ or ½ core samples of barren or low grade intervals selected from old drill core; Blank crushed samples were typically prepared form RC samples or blank rock samples, coarse rejects are generally used for this purpose; and Blank rock samples were prepared from rock samples, with part of the original sample analyzed by the Metalline laboratory when it was operang, to confirm the blank nature of the material. Discrepancies with blank samples were resolved by re-assaying pulps or coarse rejects or both if material is available as well as selected samples in the nearby sample intervals. 111 Coarse blank material for the 2011 and 2012 drill holes were inserted at a rate of one in 40 samples. The "blank" sample came from drill core intercepts from previous drill campaigns with low level or null concentraons of silver, zinc, lead and copper. The problem with this methodology is that there is not a consistent grade range for the "blank" material selected. There also is a lingering doubt as to just how inert some of the selected "blank" material is. Five samples returned values above 5 ppm silver. Of those, two were mislabeled standards. From the period of July 7 to July 20, 2011, fourteen blanks retuned values greater than 3 g/t including three samples that returned values above 5 g/t that appear to indicate a problem with the assay preparaon laboratory. As of drill hole B11099 onwards a different blank sample has been used and will be consistently used going forward. The sample BLANCO-DOL comes from a nearby dolomite mine. (SRK 2012) The Author (Reeves) reviewed the blanks used in the drill program subsequent to the last resource report and found that 538 blanks had been inserted into the sample stream. Of these, only nine samples returned greater than 0.6 g/t with one reaching 1.8 g/t Ag. The vast majority were at the detecon limit of 0.1 g/t Ag (Figure 38). Figure 38. Blank Performance between July 2012 & December 2012 112 8.2.1.6 Duplicate Samples Duplicates are used to check on sample homogeneity and laboratory precision. They were also used to detect issues associated with sample preparaon. Silver Bull submied both pulp and coarse duplicate samples. Duplicate samples were submied with a different sample number to that used for the original sample. Discrepancies and inconsistencies with duplicate samples were resolved by re-assaying pulp, reject or both. (SRK 2012) 8.2.1.7 Pulp Duplicates Pulp samples submied to a second cerfied laboratory were also used as a test of precision and accuracy. Pulp duplicates were submied with the pulp samples, previously analyzed by the Metalline laboratory. They were also submied aer results were been received from ALS as a check on laboratory precision. (SRK 2012) No pulp duplicates were run since the last resource esmate. 8.2.1.8 Field Duplicates (Aer JDS 2013) - Field duplicate samples are set at every 20th sample and are bracketed by either a blank or a standard. Field duplicates are duplicate core samples taken from selected core. The inial ½ core was split into two ¼ core samples, one of which was submied as the original sample and one of which was submied as the duplicate sample. A total of 928 field duplicate samples were taken as part of the QA/QC program for the 2012 drilling aer the SRK 2012 Resource report. Of these, 124 samples assayed below detecon limit of 0.2 g/t with another 490 reporng less than 5 g/t silver. Silver and zinc results were analyzed for Relave Difference using the following formula: Of the remaining 314 samples assaying greater than 5 g/t, 99 samples displayed a relave difference greater than 20% (Figure 39). 113 Figure 39. Silver Coarse Duplicate Assay Results with ± 20% Confidence Lines The results of the duplicate samples are acceptable given that the silver mineralizaon is to some extent fracture controlled and nuggety in nature. For zinc, of the 938 samples four samples were below detecon limit in both instances., Out of the remaining nine hundred and thirty-four pairs, 232 samples showed a Relave Difference of >20%. The majority of those samples are below ~0.70% Zn (Figure 40). 114 In summary, Silver Bull has had a Standard, Blank, or Field Duplicate QA/QC inseron rate of about every one in nine samples. The Authors are of the opinion that the sample preparaon, security and analysis meets industry standards and is adequate to support a mineral resource esmate as defined under S-K 1300. Figure 40. Zinc Field Duplicate Comparison 8.3 TERMITE HOLE COMPARISION 8.3.1 INTRODUCTION In 2013 SRK was engaged by Silver Bull to carry out an analysis of the recently completed diamond drilling at the Sierra Mojada project. Specifically, SRK was asked to evaluate if the Termite drilling (TH) could beer define and document the apparent bias that appears to exist between Long Holes (LH) and surface diamond drill holes (DH) on the property. The analysis was carried out on 206 TH and LH drilled in the same general area. The comparison was carried out by Dr. Gilles Arseneau and Mr. Michael Johnson of SRK. This secon is taken from the summary memo provided by Silver Bull and previously reported by JDS (2013). 115 8.3.2 METHODOLOGY The termite drill holes were all collared from underground platforms and are generally situated in areas with high concentration of LH. As was expected, comparing termite holes and long holes on an assay to assay basis was not very successful (Figure 41). While there was general agreement between the two types of drilling, significant differences existed at the one to two metre assay intervals. Note: Grid is 5 m x 5 m. Figure 41. Seconal Comparison of Termite Hole & LH Assays For this reason, SRK decided to compare the average grade of TH and LH over larger volumes starng with 5x5x5 m blocks, represenng the block size used in the latest resource esmate. For this comparison, the grade of all capped composites that were within a block volume from both types of drill holes were averaged and compared on quarle/quarle (QQ) plots. The QQ comparison for zinc appeared to indicate that in general the distribuon of LH assays is very similar to the distribuon of LH assays (Figure 42). 116 Figure 42. Comparison of Zinc for LH & TH However, silver grades in the LH appeared to be generally higher than in the TH, by about 25% (Figure 43 on the following page). SRK cauons that the comparison is based on a small number of blocks, less than 300, and that the differences noted between LH and TH could be an arfact of the data. SRK also compared the LH and TH using different block sizes from 10x10x10 m to 20x20x10 m and 50x25x10 m. SRK noted that while the differences between LH and TH seemed to improve for silver the opposite was true for zinc. The apparent bias for silver dropped from 25% at a 5 m blocks to less than 10% for the 20x20x10 m blocks, however the zinc bias increased to about 30% for the 20x20x10 m blocks (Figure 44). 117 Figure 43. Comparison of Silver in LH versus TH in 5 m Blocks. Figure 44. Comparison of Zinc in LH versus TH for 20x20x10 Blocks Because of the difficulties with well-informed block-to-block comparisons and because of the small number of blocks available for comparison, SRK decided to estimate block grades using LH, TH and DH data and then compare only those blocks that had been estimated by the three types of data. 118 The blocks were estimated from a minimum of five and a maximum of 18 composites. The search was set to 90 m along strike, 70 m across strike and 50 m down dip. The estimation resulted in over 10,000 blocks being estimated by the three data types. As presented in the previous study, the block estimated silver grades from LH assays on the QQ plot were on average twice the block estimated silver grades from DH assays (Figure 45). Figure 45. Comparison of Esmated LH & DH However, the comparison of LH and TH estimated silver block grades showed a very good agreement for grades lower than 125 g/t Ag (Figure 46). A comparison of esmated block grades for zinc from LH and TH assays showed a generally good agreement for grades lower than 6% (Figure 47). 119 Figure 46. Comparison of LH & TH for Esmated Blocks, all Rock Codes Figure 47. Comparison of LH & TH for Esmated Blocks, all Rock Codes. To further evaluate the differences between LH and TH, SRK evaluated the two data types by individual rock codes. The results of the analyses indicate that the differences between LH and TH are not consistent over the entire Sierra Mojada mineralization. Silver in the TH seemed to be higher than in the LH for rock 50 (above 70 g/t) while the opposite is true for rock code 10. Correlations for silver were generally good for all rock types at lower grades (below 70 g/t). 120 Zinc in the TH correlates well with the LH for grades lower than 7% in rock codes 20 and 50 see Table 11. Table 11. Summary of Correlaon between LH & TH by Rock Codes Metal Ag Zn Rock Code 10 20 40 50 10 20 40 50 Comments Good correlation up to 100 g/t, restricted grades > 125 g/t to 20 m Very low Ag values, TH higher than LH, no adjustments (could upgrade LH) not reviewed Good correlation to 60 g/t, TH are higher than LH over 70 g/t, no restriction Good correlation up to 8%, restricted grades > 8% to 20 m Good correlation up to 7% , restricted grades > 7% to 20 m Insufficient data for valid comparison, LH much greater than TH Good correlaon to 5%, restricted grades > 5% to 20 m To evaluate the lateral extent of the high-grade zone explored by underground workings, SRK compared all LH and TH assays normalized to the drill collar (i.e., all assay data were averaged based on their distance from the collar at 2 m increments). Tables 12 and 13 show the LH and TH average grades at specified distance from the collar. As can be seen from the tables, LH silver grade drops by about 35% over the first 20 m of drilling and for the same distance TH silver grade drops by 60%. Similar decrease in grade is noted for zinc in rock code 20 (Table 12). Table 12.

Figure 48. Graphical Representaon of Downhole Grade Variaon for Ag in rock code 10 123 8.3.3 TWIN HOLE PROGRAM CONCLUSIONS Overall, the exercise indicates that the Long Hole silver assay data are somewhat biased on the high side for the higher grades when compared to assays from Termite holes. The bias seems to be restricted to grade above 70 g/t or 100 g/t depending on the domain or rock code compared. Zinc grades above 7% should be restricted to 20 m in rock codes 20 and 50. SRK recommended that special care be taken when using LH data in resource estimation and that a restriction be placed on high grade in the long holes. Initial findings from the analysis of the variation of grade with depth of drilling indicate that the high grade drops relatively quickly within 20 m of collars. SRK recommended that estimates from the high grades in the underground long holes should be limited to roughly 20 m distance from underground workings. 124 9 DATA VERIFICATION In addion to the data verificaon carried out by as part of the previous technical reports for Sierra Mojada, the QP has carried out a review and validaon of the exisng drill database and data collecon procedures. No new drill holes have been added to the Mineral Resource database since the June 2015 technical report. The verificaon consisted of: · · · · · · · Review of sampling and logging procedures Validaon of the database Spot check assay cerficate data with the database Review of QA/QC procedures Inspecon of QA/QC results Review of the geological model Visual inspecon of cross secons showing assay and lithological data overlaid onto the geological model The QP considers the database fit-for-purpose and is suitable for use in the esmaon of Mineral Resources and was collected in line with industry best pracce. 9.1 DOWNHOLE SURVEYS PAH’s inial review of downhole survey informaon indicated several issues relang to improper interpretaon and processing of the survey data. To migate these issues PAH and MMC compiled all available survey data. SRK reviewed the digital downhole data and noted some minor data entry errors with the Long Hole database. These errors are not considered to be material to the resource esmaon because of the relave short length of the long holes, on average less than 15 m. (SRK 2012). Prior to the 2015 Mineral Resource esmate, Silver Bull audited the database and any survey discrepancies were checked by the on-staff surveyor. The QP reviewed the exisng downhole survey informaon and procedures. 125 9.2 ASSAY DATA Original digital assay cerficates were provided by Silver Bull and loaded into an SQL database by Archer Cathro. Individual assay results were compared to the assay results recorded in the drill database. No errors were detected that would impact the resource esmate. 9.3 CHANNEL SAMPLES, COLLARS & UNDERGROUND WORKINGS There has been no addional survey work done on void delineaon and this secon summarizes the previous work. (Tuun & AFK 2015). Three dimensional locaons of channel samples (“CH”), underground drill holes and surveyed underground workings were supplied by Silver Bull. SRK imported these data into Gems® soware, which has the capability of displaying such data in three dimensions. The channel samples and underground drill hole collars were visually compared against the underground workings. A number of inconsistencies were noted. Namely, some channel samples and collars were located several meters away from the surveyed underground workings. This implies erroneous survey data for either the channel sample/collar locaon or the underground workings. These data were excluded from the dataset prior to esmaon. In areas where channel samples had been collected but no underground workings seem to exists in the Silver Bull survey database, SRK generated wireframes to capture the addional mined out areas (Figure 59). (SRK, 2012) The QP visually inspected the void solids provided by Silver Bull to ensure they adequately represent mined material. Channel samples and underground drill hole collars were compared to the void solids. The QP found no issues that would significantly impact the resource esmaon process. 126 10 MINERAL PROCESSING AND METALLURGICAL TESTING A summary of the metallurgical work conducted on the oxide mineralizaon by Silver Bull 2010 and 2013 is outlined below. Specifically, this chapter looks at the following: · · Summary and analysis of the program on the silver and zinc mineralizaon, and then the SART circuit at the back end. Incorporaon of all results into two preliminary process flow diagrams, one for silver and one for zinc. 10.1 ORE TYPES The metallurgical program conducted by Silver Bull between 2010 and 2013 looked at the silver and zinc zones separately in order to obtain an understanding of the process parameters for each ore type. The process flow sheets were developed to handle all of the silver ore types in one flow sheet, with a second flow sheet being developed to handle all of the zinc ore types. The goal was to allow a situaon wherebyone of the flow sheets may be converted to the other flow sheet if a mine plan can be developed for first mining the silver mineralizaon which sits spaally on top of the zinc mineralizaon. The mineralizaon at Sierra Mojada can be broken into a silver zone located at surface at the west end of the deposit, before dipping underground at an angle of 6 to 7 degrees towards the east, and a zinc zone which sits underneath the silver mineralizaon at the eastern end of the deposit (Figure 49). 127 Figure 49. The locaon of the silver and zinc zones of mineralizaon The silver zone can be broken down further into three disnct silver areas (see Figure 50). Shallow Silver Zone, Centenario Zone, and the Fronteriza Zone. 128 Figure 50. Silver metallurgical Sample Locaons The zinc zone can also be broken down into two disnct areas. Red Zinc zone and the White Zinc zone. 10.2 TEST WORK Metallurgical test work at Sierra Mojada occurred over several phases between 2010 and the end of 2013 and was conducted at several mineral processing laboratories including: Mountain States Research and Development Intrernaonal Inc., and Kappes Cassidy & Associates Inc. for the silver mineralizaon, and Hazen Research Inc. and SGS Lakefield Ontario Inc. for the zinc mineralizaon. The test work on the SART process was conducted by BiotecQ Ltd. out of Vancouver and was performed on the pregnant soluon recovered from the testwork completed at Hazen Research Inc. 10.2.1 MOUNTAIN STATES R&D – SILVER RECOVERY TESTS The metallurgical test work related to the silver mineralizaon seen at Sierra Mojada mineralizaon in 2010 by Silver Bull at Mountain States Research and Development Internaonal, Inc. located southeast of Tucson, Arizona. Three samples were taken from a trench, which was excavated along the surface of the Shallow Silver deposit (see Figure 51). 129 Figure 51. Locaon of the Trench Metallurgical Sample Taken in Early 2010. The geology and sample locaon from the trench are shown in Figure 51. Of the three metallurgical samples taken only samples Met Sample 1 and Met Sample 3 were tested, no cyanidaon test work was performed on Met Sample 2 due to high plumbo-jarosite content. Met Sample 1 was later composited into ‘Compo1’ and Met Sample 3 was composited into ‘Compo2’. Mountain States performed two series of tests on the Compo1 and Compo2 samples. The first series looked at a standard cyanide leach bole roll test and compared grind size to silver recovery. The second series of tests looked at increasing cyanide concentraons in the leach soluon versus the silver recovery. The test parameters and the results are shown in Tables 15 and 16, respecvely. 130 Table 15. Mountain States Grind Size versus Silver Recovery Results.

Work has focused on cyanide leach recovery of the silver using “Bole Roll” tests to simulate an agitaon leach system common on many mine sites. Samples were composed of the composite samples prepared by Mountain States and supplemented with addional samples taken separately from drill core, mineralized outcrop, and trenches from the “Centenario”, “Fronteriza” and “Shallow Silver” Zones of the silver mineralizaon. These were crushed and mixed to create either a “composite” sample representave of each of the 3 zones, or a series of composite samples based on the silver grade for each of the three zones. KCA began their test work by performing diagnosc leach test work on 5 composites from the Shallow Silver Zone and 5 composites on the Centenario Zone. Table 18 lists the results of this test work and Figure 52 shows the results graphically. Table 18. Diagnosc Leach Test Work – Cumulave Silver Extracon.

KCA Silver Zone Diagnosc Leach Test on the Shallow Silver and Centenario Zones The results suggested silver mineralizaon is amenable to direct cyanide leaching. The informaon from the diagnosc leach tests at various silver head grades also provided insight as to the relaonship between silver recovery and silver head grade. Figure 53 shows a graphic display of this relaonship. 134 Figure 53. Shallow Silver Zone Diagnosc Leach Tests Ag Recovery vs. Ag Head Grade Addional test work on the three silver zones at Sierra Mojada at KCA in 2012 was completed with work focusing on leach soluon cyanide strength, pH, lead nitrate addion, grind size, and increased oxygen concentraons.

Silver recovery is somewhat grind size sensive with finer grinds giving higher recoveries. Varying levels of cyanide consumpon (NaCN) are aributed to variable amounts of zinc and copper in the samples. Current target for grind size is 40 microns. Current target for NaCN concentraon is 5.0gpl in the leach soluon, maintained. Average silver recovery is expected to approach 75% at a grind of 40 microns and a leach soluon NaCN concentraon of 5.0gpl 10.2.2.2 The SART circuit and Zinc Recoveries In addion to the silver test work via cyanidaon, work was completed in the first quarter of 2013 to confirm the Sulfidizaon, Acidificaon, Recycling and Thickening (SART) process and its applicaon at the backend of the leaching circuit. The SART circuit allows for the recycling of the cyanide in the silver leaching circuit –lowering cyanide costs, as well as potenally recovering a poron of the zinc and copper observed in the Sierra Mojada silver deposits. The following two tables provide a summary of the zinc and copper recoveries observed in the cyanide leach tests from the mineralizaon at Sierra Mojada. Table 20.

KCA produced 40 liters of barren leach soluon (pregnant leach soluon with the silver removed with zinc dust) for tesng at BioteQ in BC, Canada. The SART test work results are summarized in Table 22. The test work results showed that the 100% of the zinc in the barren Merrill Crowe soluon can be recovered and a saleable zinc concentrate produced. Table 22. Summary of the SART test work results completed by Bioteq. 10.2.3 HAZEN TEST WORK – TREATMENT OF HIGH GRADE ZINC Hazen Research in Golden, CO, was tasked with looking at the potenal for using a pyrometallurgical technique for treang the zinc ores. A process for producing ZnO from steel plants and other metal manufacturing facilies waste by-products, known as the Waelz Kiln process, was tested at Hazen in 2012. Hazen received composite samples from both the Red Zinc and White Zinc deposits at Sierra Mojada. This material was tested in one of Hazen’s higher temperature kilns at temperatures between 1,100ºC and 1,300ºC. The process involves mixing into the ore a reducing material, such as carbon or coal, heang the ore mixture to the required temperature, fuming off the Zn, passing the fumed Zn gas to an oxygen atmosphere and cooling the gas, forming a ZnO precipitate. 137 In the Hazen test facility zinc fuming worked very well with zinc fumed from the ore at greater than 90 percent. However, difficulty in recovering the ZnO as the precipitate was evident as metal accounng for the tests were very poor. Zinc was found to precipitate on the test apparatus wherever the temperature was cool enough for the zinc to precipitate. Table 23 provides a summary of the results from the Hazen test program. The Waelz Kiln concept was proven to work on the zinc ores. However, difficules experienced by Hazen to capture the ZnO and difficules in maintaining the kiln caused the program to be halted. 138 Table 23.

Work focused on heavy media separaon (HMS) and flotaon recovery of the zinc minerals hemimorphite (Red Zinc) and smithsonite (White Zinc). Test work using bench scale heavy liquid separaon and flotaon tests were used to develop possible process parameters for a zinc HMS/flotaon circuit. Samples had been taken from drill core and channel samples along the 1.5 kilometer strike length of the “Red Zinc Zone” and “White Zinc Zone” of the deposit. The samples were then crushed and mixed to form a composite sample representave of each of the material types present in the deposit. The primary focus for the SGS test Work program were the zinc materials. They were also tasked with finding a method to produce a saleable zinc product from the Red Zinc and White Zinc materials. The SGS program was focused on using Heavy Media Separaon and Flotaon to produce a concentrate. The following tests and results have been obtained by SGS to date: 10.2.4.1 White Zinc Test work White Zinc (smithsonite) Heavy Media Separaon and Flotaon is effecve and can obtain a 42% Zn Concentrate. The heavy media separaon was very effecve as roughly 53% of the zinc was recovered in the HMS alone into a concentrate that assayed over 45% Zn. Addional test work is needed to refine the heavy media and flotaon recoveries. Flotaon results for the White Zinc were also very good, with a best case 40% Zn concentrate being produced while recovering 96.5% of the zinc. Test Work Reagents and Results for the best case test on White Zinc Master Composite are shown below in Tables 23 and 24. Figure 54 shows the Zn recovery versus concentrate Zn grade for the White Zinc best case test. 140 Table 24. Flotaon Reagent Suite White Zinc Master Composite.

White Zinc (Smithsonite) Zn Recovery vs. Concentrate Zn Grade 10.2.4.2 Red Zinc Test work Red Zinc (hemimorphite) Heavy Media Separaon and Flotaon has been shown to be a bit more complicated due to slimes (< 38 µm parcle sizes) generaon during grinding. Test work shows that the flotaon of the + 38 µm material is good with 72.5% of the zinc recovering to a 30% Zn concentrate. Red Zinc has a propensity to slime as the natural grain size of the material is very fine. As received material has been observed to have greater than 20% -38 µm material. HMS of this material was somewhat effecve as roughly 57% of the zinc was recovered to a concentrate that was above 22% zinc. More test work on HMS of the Red Zinc material should be performed to see if concentraon raos can be improved or if cleaning stages can improve concentrate grades. The slimes performed poorly in flotaon test work with only 55% of the zinc reporng to a 22% Zn concentrate. In the SGS test work roughly 45% of the Red Zinc ore ended up in the slimes making slimes migaon a major concern in future test work. Opons to consider include: Stage grinding with screening in between to reduce the amount of fines generaon. Ulizing fine bubble flotaon cell technology developed specifically for fines/slimes flotaon. Sodium silicate addion as an aid in slimes flotaon. Flash flotaon in the grinding circuit to float material prior to fines generaon.

Red Zinc (Hemimorphite) Zn Recovery vs. Concentrate Zn Grade The next step will be to run addional tests using Dense Media Separaon (DMS) at small scale to generate a pre-concentrate. It is ancipated these tests will replace the HLS test work previously performed to beer simulate an actual producon flow sheet. The DMS concentrate should have fewer negave effects on downstream flotaon. This test work will then need to be followed by test work to find a way to reject Fe bearing materials, which appears to be the main impurity in the final DMS concentrate. Test work to improve slimes flotaon will also need be performed using a Jameson or similar cell which ulizes fine bubble generaon. Concentraon of the Red Zinc in parcular is expected to perform beer in a fine bubble floataon machine such as a Jameson Cell, which is specifically designed to migate the sliming problem. Based on current test work results the following conclusions about the zinc flotaon can be made: White Zinc performs very well in a standard flotaon scheme. A zinc recovery of 87% at a concentrate grade of 43% zinc can be achieved. Red Zinc is more difficult to float than the White Zinc due to the sliming characteriscs of the Hemimorphite mineral. Red Zinc test work to date can produce a 30% zinc concentrate at a zinc recovery of 72.5%. 144 10.3 ORE PROCESSING The Sierra Mojada Project will require two disnct flow sheets and process facilies for the silver ores and the zinc ores. The silver ores will ulize cyanide leach technology and the zinc ores will ulize Heavy Media Separaon and Flotaon. Some of the unit operaons can be used in both facilies, such as crushing and grinding. A discussion on how the equipment can be ulized for both process scenarios will be discussed at the end of this secon. Since the silver and zinc ore processing facilies are somewhat disnct, they are discussed separately in this report. 10.3.1 SILVER ORE PROCESSING A simple flow diagram has been developed and is shown in the following Figure 56. It is envisioned that the silver ores at Sierra Mojada will require a crushing and grinding circuit to produce a parcle size P80 of 53 microns to maximize silver recovery and project economics. Following grinding, a cyanide leach and CCD circuit will be ulized with the pregnant leach soluons reporng to a Merrill Crowe silver recovery plant. Once the silver has been recovered, cyanide recovery, as well as, zinc and copper recovery will take place in a SART facility. Tailings from the leach circuit will be detoxified in a cyanide destruct circuit before reporng to a tailings storage facility. Water will be reclaimed from the tailings storage facility for reuse. Products produced will include silver doré, and a zinc sulfide precipitate. 145 10.3.2 ZINC ORE PROCESSING A simple flow diagram has been developed and is shown in the Figure 57. Figure 56. Proposed Process Block Flow Diagram for the silver ore It is envisioned that the zinc ores at Sierra Mojada will require a crushing circuit to produce a parcle size P80 of 3.66mm to feed a dense media separaon (DMS) unit with the +48 mesh sink fracon reporng to a rod mill for addional grinding prior to flotaon. The final grind size is currently esmated at a P80 of 105 microns which should maximize zinc recovery, minimize slimes producon, and maximize project economics. Following grinding, slimes separaon will be performed with the slimes poron reporng to a fine bubble flotaon cell, such as a Jameson cell. The coarser fracon will report to a standard flotaon circuit. Both the slimes and coarse flotaon circuits will incorporate one or more cleaning stages to improve the zinc content of the concentrate. Concentrates will be thickened, filtered, and dried followed by loading into train cars for bulk shipment to a zinc refinery. Tailings from the flotaon circuit will be thickened before reporng to a tailings storage facility. 146 Water will be reclaimed from the tailings storage facility for reuse. The products produced will be a Hemimorphite and Smithsonite concentrate. A concentrate could then be further refined through kilning. Figure 57.

The following secons detail the method and strategies used to esmate the mineral resource. This resource esmaon was completed by Mahew Dumala, P. Eng., an independent qualified persons as defined in S-K 1300. The effecve date of the resource statement is October 1st, 2018. Work at the Property conducted aer 2018 focussed on deeper sulphide mineralizaon and does not impact the Mineral Resource Esmate. Geovia GEMS 6.7.2.1 soware was used to model surfaces and solids that define the boundaries of the deposit. The soware was also used for block modeling, grade esmaon, and resource reporng. Snowden Supervisor v8.7 was used to determine basic stascs, geostascs, and variography. The current Mineral Resource esmate was completed using the same database as the previous Mineral Resource (June 8, 2018). It has been restated to reflect current metal prices and changes to Mineral Licences. 11.2 RESOURCE DATA BASE The Sierra Mojada Project drill data was provided to Archer Cathro as a GeoviaTM GEMS database. The database used in the resource esmate was audited by Archer Cathro prior to esmaon. The Author is of the opinion that the data is sufficiently reliable to interpret with confidence the boundaries of the deposit for the esmaon of tonnes and grades of the four metals: zinc, copper, lead and silver. The drill hole data base consists of 12,772 surface and underground diamond drill holes, reverse circulaon drill holes, long holes, underground channel samples and a surface trench sample intended for a metallurgical bulk sample test. Of these 12,772 holes and channel samples, only 12,733 were used to esmate the Mineral Resource. These are listed in Table 28 below. 148 Table 28.

These define geological surfaces, faults, topography, mineralizaon, and underground. These solids and surfaces are unchanged from the 2015 Mineral Resource esmate. The underground workings are complex with numerous small adits, declines, dris, cross-cuts, stopes and shas as described earlier in this report. They had been surveyed in small segments over the years but never combined. The workings are shown in Figure 58 with the mining areas colour-coded by the main mining area: · · · · · Centenario/Fronteriza – blue Encantada – green Esmeralda – teal Parreña – magenta San Salvador – red Some workings were inaccessible due to collapse or unsafe condions. Based on historical mining records it appears that, based on an average density (~2.7), only about 12-15% of property-wide mined workings have been surveyed. Some of the workings (e.g. Parreña) are clearly development in waste or in mineralized zones outside the current Mineral Resource area. The volume within the zone is not considered to be significant compared to the mineralized zone. 149 The volumes for the validated solids are summarized in Table 29. Table 29.

Figure 58. Underground Workings A single solid represenng mineralizaon was constructed by Silver Bull staff from available informaon including assays, faults and interpreted geologic secons. Figure 59 is an example of the geologic interpretaon along Secon 631600E through the San Salvador - Centenario block, while Figure 66 shows the mineralized solid overlaid onto the same Secon. 150 Figure 59. SBR Geologic Interpretaon 631600E (+/- 50m window) Figure 60. Secon 631600E - Mineral Zone Wireframe 151 The lower dashed line yellow area on Figure 59 is the white zinc (smithsonite) chimney zone. While the wireframe has a jagged appearance in 3D (Figure 61), it does an acceptable job of capturing the complexity of the carbonate replacement deposit where deposion is assumed to have been via the main Sierra Mojada Fault system with leakage along northern and north- westerly faults. The wireframe intersecon with the plane is magenta. The surfaces and solids were then used to create rock, density and percentage block models. The percentage block models were for topography, mineral zone, and underground workings (voids). The rock codes used for modeling are shown in Table 30. Figure 61.

Solids provided by Silver Bull represenng mineralized zones were used to code samples. Samples not within these mineralized solids do not impact the Mineral Resource esmate The descripve stascs for the sample data within the mineralized solid is shown in Table 31, while correlaon coefficients are shown in Table 32.

This plot shows that silver grade is relavely evenly distributed. There is a second populaon of lower grade mineralizaon. Some of these are believed to represent edge cases along the mineralized solid boundaries where low grade samples were included in the mineralized solid. 153 Figure 62. Silver Log-Histogram plot 11.2.3 CAPPING AND COMPOSITING One metre composite were chosen because the majority of samples are 1.0 m long. The mean length of samples within the mineralized solid is 1.10 m and median length is 1.00 m. Samples were composited down-hole honouring the mineralized solid. Composites less than 0.5 m were not calculated. Composites exceeding the high-grade limit were limited to 20 m (2 blocks) in any direcon. It is the Author’s opinion that liming the range of influence of composited high values is appropriate for this project since the area has a mining history that included legimate high grade silver (Veta Rica) and high grade zinc mines (Fronreza, Esmeralda, Encatada etc). High-grade limits were set to approximately the 99th percenle for each element. The composing shows an improvement in the coefficient of variaon but lile changes in other basic stascs (Table 33) within the data set. There are no strong correlaons between metals (Table 33) within the data set. There are no strong correlaons between metals ( Table 34). 154 Table 33.

Composite Silver Histogram Figure 64. Composite Zinc Histogram 156 11.2.4 BULK DENSITY ESTIMATION Density for waste rock is based on approximately 3,500 samples from various rock types. This data had not been tabulated with corresponding Hole-ID and “From-To” informaon so could not be used for Inverse Distance Squared (ID2) modeling. Instead, the average values had been used to populate the model. Background waste rocks from that work is summarized in Table 14-3 with the corresponding Block Model rock codes. Using an average value in the mineralized zone fails to recognize variability due to very high zinc or lead grades. A total of 1,985 addional samples were taken and density measured by the use of a pycnometer loaned by the neighbouring Peñoles La Dolomita Mine. These samples were used to esmate the density of the mineralized zone by the use of the ID2 technique. 11.2.5 GEOSTATISTICAL ANALYSIS AND VARIOGRAPHY Variograms were calculated for silver, copper, lead and zinc composites within the mineralized solid to produce inputs for the esmate. Horizontal connuity was modeled first using eighteen horizontal variograms at 20o increments. Connuity models were then created for the across strike and dip plane orientaons. Once the direcon of maximum connuity was selected, a down-hole linear semi-variogram was created to determine the nugget effect. Nested exponenal models were fied for all elements as summarized in Table 35. The anisotropy was assessed using Azimuth, Dip, and Azimuth (ADA) rotaon. Table 35. Semi-Variogram Parameters. Metal Ag Cu Pb Zn Azim 111.5 106.4 100.3 110 Dip -3.5 -6.3 -3.4 0 Azim 18.0 13.5 9.7 N/A Co 0.16 0.25 0.24 0.21 C1 0.48 0.55 0.26 0.55 C2 0.36 0.20 0.50 0.24 X (m) 47 201 29 188 34 180 55 205 Y (m) 34 139 19 115 22 133 35 144 Z (m) 29 121 16 100 18 95 52 157 157 While the deposit has a very strong east-west orientaon sub-parallel to the Sierra Mojada Fault, connuity is disrupted by numerous north and north-westerly faults. Displacements within the mineralized zone are generally minor as has been noted during underground mine tours. These displacements have had a minor effect on anisotropy as an easterly plunge is apparent. 11.3 BLOCK MODEL DEFINITION The block model origin and orientaon and size are the same as the previous Mineral Resource esmate. The block model is not rotated and parameters are summarized in Table 36. Minimum Maximum Block Size No. Blocks Table 36.

Supervisor was used to perform a Kriging Neighbourhood Analysis to validate the block size and esmaon parameters. 11.3.1 GRADE INTERPOLATION Block model grades were esmated in three passes using Ordinary Kriging (OK) with the minimum and maximum samples and searches as summarized in Table 37. The classificaon methodology used was that blocks meeng the criteria of Pass 1 would be flagged as Measured; Pass 2 – Indicated; and Pass 3 – Inferred. 158 Silver, copper, lead and zinc were esmated using Ordinary Kriging (OK) on uncapped composited 1.0m grades.

The level of geological uncertainty associated with an inferred mineral resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extracon in a manner useful for evaluaon of economic viability. Because an inferred mineral resource has the lowest level of geological confidence of all mineral resources, which prevents the applicaon of the modifying factors in a manner useful for evaluaon of economic viability, an inferred mineral resource may not be considered when assessing the economic viability of a mining project, and may not be converted to a mineral reserve.” 159 “Indicated Mineral Resource is that part of a mineral resource for which quanty and grade or quality are esmated on the basis of adequate geological evidence and sampling. The level of geological certainty associated with an indicated mineral resource is sufficient to allow a qualified person to apply modifying factors in sufficient detail to support mine planning and evaluaon of the economic viability of the deposit. Because an indicated mineral resource has a lower level of confidence than the level of confidence of a measured mineral resource, an indicated mineral resource may only be converted to a probable mineral reserve.” “Measured Mineral Resource is that part of a mineral resource for which quanty and grade or quality are esmated on the basis of conclusive geological evidence and sampling. The level of geological certainty associated with a measured mineral resource is sufficient to allow a qualified person to apply modifying factors, as defined in this secon, in sufficient detail to support detailed mine planning and final evaluaon of the economic viability of the deposit. Because a measured mineral resource has a higher level of confidence than the level of confidence of either an indicated mineral resource or an inferred mineral resource, a measured mineral resource may be converted to a proven mineral reserve or to a probable mineral reserve.” The guideline commentary also clarifies that the phrase “reasonable prospects for economic extracon” implies a judgment by the Qualified Person in respect of the technical and economic factors likely to influence the prospect of economic extracon. A Mineral Resource is an inventory of mineralizaon that under realiscally assumed and jusfiable technical and economic condions might become economically extractable.” Blocks were classified as measured, indicated, and inferred based upon the OK pass they were esmated. Blocks esmated in the first pass are considered measured, while blocks that were esmated during the second pass were classified as an Indicated category. All other blocks esmated are considered Inferred. This method of classificaon is consistent with standard industry pracces. Blocks esmated in the first pass are spaally closer to more sample locaons and therefore can be considered to have a higher level of confidence than blocks esmated in later passes. 11.3.3 BLOCK MODEL VALIDATION The block models were visually validated by comparing the blocks esmated with actual drill hole composite data on both secon and in plan view. Figure 65 and Figure 66 are secon and plan respecvely. Composite grades are a good match to the esmated block grades. 160 Figure 65. Secon 631500E Zinc blocks versus Zinc grades. Figure 66. Planview 1355 Elevaon Zinc Blocks vs Zinc grades. 161 In addion, nearest neighbor (NN) model and inverse distance squared (IDS) models were generated for comparison to the ordinary kriged (OK) model. Table 38 shows the zero cut-off totals and percentage differences of the esmates. The nearest neighbor model represents an unbiased esmate. The similarity of the three models further validates that OK is an appropriate method for the resource esmate. Table 38.

Figure 67. Silver Grade Tonnage Curve 162 11.4 MINERAL RESOURCE ESTIMATE Figure 68. Zinc Grade Tonnage Curve To demonstrate “reasonable prospects for economic extracon”, Archer Cathro generated a conceptual pit shell based on the parameters listed in Table 39 using Geovia While 4.7.2. These parameters are derived from the JDS PEA Nov 2013 using silver and zinc processing consideraons and summarized in Secon 10. The silver ores will ulize cyanide leach technology and the zinc ores will be blended into the ore feed stream to allow for zinc recovery in the SART (Sulfidizaon, Acidificaon, Recycling and Thickening) process. Silver and zinc metal prices were chosen to be consistent with five year averages, which is believed to be sufficient long enough period to balance errac price fluctuaons in the past two years. It is the QP’s opinion that these prices are adequate for the determinaon of “reasonable prospects for economic extracon”. The material factors that could cause actual results to differ materially from the conclusions, esmates, or designs in the following secon include any significant differences from one or more of the material factors or assumpons that were set forth in this secon including cut-off grade assumpons, and product pricing forecasts. Results of the Sierra Mojada conceptual open pit Mineral Resource esmate are shown in Table 40 at a $13.50 NSR cut-off. Net smelter return (“NSR”) (US$/tonne) values were calculated for each block for silver and zinc based on the parameters listed in Table 39 Below. 163 Table 39.

Risk factors that could potenally affect the Mineral Resources esmates include: · · · · Assumpons used to generate the conceptual data for consideraon of reasonable prospects of economic extracon including: · · long-term commodity price assumpons changes in local interpretaons of mineralizaon geometry and connuity of mineralizaon zones · metal recovery assumpons · concentrate grade and smelng/refining terms. The esmated tonnage of mineralizaon to be mined may vary as infill drilling provides more detailed informaon about characteriscs, thickness and connuity of grade in the deposit. Delays or other issues in reaching agreements with local communies Changes in perming requirements It is the QP’s opinion that technical factors that are likely to influence the prospect of economic extracon, including geological interpretaons and metallurgical recovery, can be resolved through addional testwork and drilling. Issues related to exisng agreements and perming requirements believed to be able to be resolved. 167 12 MINERAL RESERVE ESTIMATES Not applicable to this report. 168 13 MINING METHODS Not applicable to this report. 169 14 PROCESS AND RECOVERY METHODS Not applicable to this report. 170 15 INFRASTRUCTURE Not applicable to this report. 171 16 MARKET STUDIES Not applicable to this report. 172 17 ENVIRONMENTAL STUDIES, PERMITTING AND PLANS, NEGOTIATIONS OR AGREEMENTS WITH INDIVIDUALS OR GROUPS Not applicable to this report. 173 18 CAPITAL AND OPERATING COSTS Not applicable to this report. 174 19 ECONOMIC ANALYSIS Not applicable to this report. 175 20 ADJACENT PROPERTIES All of Silver Bull’s holdings cover all the mineralized zones, and while the Sierra Mojada District and the Sierra Mojada property has been the subject of past producon, there are currently no adjacent properes or operators publicly reporng resources or reserves. The only commercial mining operaon acve within the area is the adjacent dolomite quarrying operaon of Peñoles. The quarry has a small staff (<25) that work a five-day week, 8 hour day shi only, to produce material for their plant at Laguna del Rey. Waste rock is stockpiled on land that they have surface rights. No informaon from adjacent properes was used in the compleon of this report. 176 21 OTHER RELEVANT DATA AND INFORMATION On September 30, 2019 Silver Bull halted all work on the Sierra Mojada project due to a blockade by a cooperave of local miners called Sociedad Cooperave de Exploración Minera Mineros Norteños, S.C.L. (“Mineros Norteños”). Silver Bull has an agreement with Mineros Norteños on Unificaon de Minera Nortenos and Vulcano mineral licences which cover the eastern part of the Sierra Mojada deposit. These licences are subject to a 2% producon royalty capped at US$6.875 million (“the Royalty”). Payment would go to Mineros Norteños should a mine go into producon. Since 2014, Silver Bull had been fighng a lawsuit by Mineros Norteños seeking payment of the Royalty, including interest at a rate of 6% per annum since August 30, 2004, even though no revenue has been produced from the applicable mining concessions. Mineros Norteños also sought payment of wages to the Mineros Norteños members since August 30, 2004 under this agreement, even though none of the individuals were hired or performed work for Silver Bull under this agreement and Silver Bull did not commit to hiring them. On October 4, 2017, the court ruled that Mineros Norteños was me barred from bringing the case. On October 19, 2017, Mineros Norteños appealed this ruling. On July 31, 2019, the Federal Appeal Court held the original ruling. This ruling was been subsequently challenged by Mineros Norteños. On March 31, 2021 Silver Bull announced it had won the law suit against Minera Nortenos and the courts agreed Silver Bull did not owe Minera Nortneos any royalty payments unl the mine goes into producon. In an aempt to force Silver Bull into making a selement before the final court ruling is issued on March 31, 2022, Mineros Norteños undertook to illegally block access to the project. To ensure the safety of all involved, Silver Bull elected to halt all operaons on the project unl a resoluon can be found. Despite the court ruling in its favor, and the fact that Silver Bull has at all mes proceeded in accordance with the law, the Sierra Mojada project remains under an illegal blockade. To date the Mexican authories have refused to intervene despite the blockade clearly being in violaon of the law. Silver Bull connues to engage in good faith dialogue with selected members from Minera Norteños to try and find a soluon that facilitates the resumpon of work on the project. 177 22INTERPRETATIONS AND CONCLUSIONS 22.1 INTERPRETATIONS AND CONCLUSIONS The alteraon-mineralizing events have generated two types of mineralizaon in the Sierra Mojada district; The Shallow Silver Zone (SSZ) and the Base Metal Manto Zone (BMM). Mineralizaon in the Shallow Silver Zone is dominated by acanthite, the silver halide solid soluon of bromargyrite-chloragyrite, and tennante. Silver occurs in early to late high grade structures, karst breccias, low-angle fault breccias, and mantos, and as disseminated replacements in porous hydrothermally altered dolomites. The Base Metal mineralizaon is dominated by hemimorphite in the Red Zinc zone and smithsonite in the White Zinc zone. Mineralizaon primarily occurs as replacement of karst breccia and accessory faults which feed the breccia zones. Nonsulfide Base Metal mineralizaon is a result of oxidaon and supergene enrichment of an original zone of semi-to massive pyritesphalerite-galena ore largely located in the Lead zone manto mineralizaon. The result is a silver (copper) rich polymetallic zone of mineralizaon overlaying a large non-sulfide zinc-lead resource, both forming a linear zone of manto shaped mineralizaon cross cut by mineralized structures. (Tuun & AFK 2015). It is the QP’s opinion that the Mineral Resource block model is representave of the informing data and that the data is of sufficient quality to support the Mineral Resource Esmate. The esmated tonnage of mineralizaon to be mined may vary as infill drilling provides more detailed informaon about characteriscs, thickness and connuity of grade in the deposit. 22.2 DEPOSIT MODEL CONCLUSIONS Sierra Mojada is a polymetallic Pb-Zn-Ag-Cu district and it represents the distal expression of Carbonate Replacement Deposit (CRD) mineralizaon which is well documented in northern Mexico. The Sierra Mojada district demonstrates a well-known base metal zoning paern overprinted by silver mineralizaon. (Tuun & AFK 2015) Silver Bull recognizes the importance of cross-cung structures for fluid-flow and the resultant “chimney” effects seen in parts of the white zinc and red zinc zones. A beer understanding of the major structures (e.g. Calabassos) will help to delineate future targets such as the Parreña. (Tuun & AFK 2015) 178 22.3 RESOURCE MODELING CONCLUSIONS Silver Bull Resources connues to employ state of the art exploraon techniques at Sierra Mojada. All data collected is managed in Microso Excel or Access, and then transformed to a visual format in MapInfo. AutoCAD is also used for tracking mineral leases, surface and claim boundaries and locang shas and adits. The current Mineral Resource ulizes a single wireframe that encompasses the carbonate replacement deposit. This eliminates “hard boundaries” and allows more samples to be available for esmaon. Conceptual pit shells generated to demonstrate “reasonable prospects for economic extracon” were primarily driven by zinc resources. This further highlights the importance of the deeper zinc zones at Sierra Mojada. 179 23RECOMMENDATIONS The authors recommend the next phase work program for Silver Bull Resources to consider on the oxide mineralizaon should include: · · · · · · · Complete addional metallurgical test work on both the silver and the zinc to confirm recovery parameters. Consider a pilot-plant program to prove the viability of the selected process The next phase work program should include geotechnical drilling to confirm appropriate slope angles for future open pit design work. Connue underground diamond drill work for improved interpretaon and modeling of domains. Detail power and water sources, requirements, and begin all perming processes. Examine the potenal of the silver and zinc zones as stand-alone minable resources. Conduct a Preliminary Economic Assessment (PEA). Connue to explore the property with an emphasis on targeng potenal sulphide targets. The Authors esmates that the total cost of the next phase work program is approximately US$2.0M. Table 43.
