PART I In this annual report on Form 10-K, unless the context otherwise requires, the terms “we”, “us”, “our”, “Vista”, “Vista Gold”, or the “Company” refer to Vista Gold Corp. and its subsidiaries. References to AUD or A$ refer to Australian currency and USD or $ refer to United States currency, all in thousands, unless specified otherwise, except per share- related, per tonne, and per ounce amounts. Overview Vista Gold Corp. and its subsidiaries operate in the gold mining industry. We are focused on evaluation, acquisition, exploration and advancement of gold exploration and potential development projects which may lead to gold production or value adding strategic transactions such as earn-in right agreements, option agreements, leases to third parties, joint venture arrangements with other mining companies, or outright sales of assets for cash and/or other consideration. We look for opportunities to improve the value of our gold projects through exploration drilling and/or technical studies focused on optimizing previous engineering work. We do not currently generate cash flows from mining operations. The Company’s flagship asset is its 100% owned Mt Todd gold project (“Mt Todd” or the “Project”) in Northern Territory, Australia (“NT”). With the approval of the Mining Management Plan (“MMP”) in June 2021, all major operating and environmental permits for Mt Todd have been received. Mt Todd is one of the largest and most advanced undeveloped gold projects in Australia. In 2022, Vista completed a feasibility study for Mt Todd (“Mt Todd FS”), retained CIBC Capital Markets as a strategic advisor to support the Company’s strategic outreach process for Mt Todd, concluded a drilling program to demonstrate district-scale resource growth potential, and significantly reduced costs. These accomplishments advanced Mt Todd’s reserve size, resource growth potential, economic returns, and overall attractiveness as a large, development ready gold project. The Mt Todd FS demonstrates the potential of a large-scale gold project at Mt Todd. Highlights include: • • • • • estimated proven and probable mineral reserves increased by 19% to 6.98 million ounces of gold (280 Mt at 0.77 g Au/t) using a gold price of $1,125 for the reserve estimate and a cut-off grade of 0.35 g Au/t(1)(2); average annual production of 395,000 ounces of gold over a 16-year mine life at an average cash cost of $817 per ounce; high capital efficiency, with initial capital requirements of $892 million, or $141 per payable ounce of gold; after-tax NPV5% of $999.5 million and internal rate of return (“IRR”) of 20.6% at a gold price of $1,600 per ounce; and after-tax NPV5% of $1.7 billion and IRR of 29.4% at a price of $1,900 per ounce of gold. (1) Note to investors: Proven and probable mineral reserves are estimated in accordance with S-K 1300 (as defined below) and CIM Definition Standards (as defined below). (2) See “Item 2. Properties – Mt Todd Gold Project, Northern Territory, Australia – Mineral Resources and Mineral Reserve Estimates” in this annual report on Form 10-K for additional information. The Mt Todd FS included reserve estimates pursuant to subpart 1300 of Regulations S-K (“S-K 1300”) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Canadian Institute of Mining Metallurgy and Petroleum Definition Standards for Mineral Resources and Mineral Reserves (“CIM Definition Standards”) based on mine plans developed using a gold price in line with the current market conditions at the time of the study. The Mt Todd FS addressed recommendations from the 2019 pre-feasibility study, included minor updates of the Project design to be consistent with the MMP, and reflected the completion of engineering and detailed costing in all areas of the Project. 2 We have invested over $110 million to systematically explore, evaluate, engineer, permit and de-risk Mt Todd since we acquired it in 2006. In recent years, we completed a number of optimization studies, which were incorporated into the Mt Todd FS. This work has added substantial value to the Project and positions Mt Todd for near-term development. The strategic process with CIBC Capital Markets, which is ongoing and remains a top priority, continues to generate interest and positive feedback on the technical merits of Mt Todd. The Company believes that there are indications that market conditions are improving, but interested parties continue to maintain a cautious approach to new, large-scale development projects. To address this, the Company is evaluating a smaller scale project with significantly lower initial capital costs while maintaining operating costs similar to those in the Mt Todd FS, with potential for subsequent throughput expansion or mine-life extension. We expect to be able to demonstrate this alternate development strategy early in 2023 and believe this should attract the interest of new potential partners and those who have previously expressed interest in different development strategies. In 2022, the Company completed an exploration drilling program within a 5.4 km trend extending immediately north from the Batman pit. The Company believes that the results from this program and historical sources demonstrate excellent resource growth potential, including delineation of four highly prospective exploration targets. The Company views these targets as positive indicators of future resource growth potential to interested parties, and believes these targets represent the closest and most immediate opportunity for growth with the appropriate investment in additional drilling. Vista has no immediate plans to complete additional drilling but continues to advance exploration on the exploration licenses, which cover 1,650 km2. We significantly reduced our 2022 recurring costs, which were approximately 15% below plan. Reducing costs and maximizing cost effectiveness are also high priorities for 2023. We have already taken steps to further reduce recurring costs by approximately 7% during 2023 and continue to evaluate and implement opportunities for additional cost reductions. In addition to the technical advancements of the Project in 2022, Vista has all major operating and environmental permits for the development of Mt Todd. We have invested significant resources in water treatment and management, environmental, and social programs. We believe this has benefited our relationships with the traditional landowners, local communities, and Northern Territory, Australia (the “NT Government”), creating a strong social license. Vista was originally incorporated on November 28, 1983 under the name “Granges Exploration Ltd.” It amalgamated with Pecos Resources Ltd. during June 1985 and continued as Granges Exploration Ltd. In June 1989, Granges Exploration Ltd. changed its name to Granges Inc. Granges Inc. amalgamated with Hycroft Resources & Development Corporation during May 1995 and continued as Granges Inc. Effective November 1996, Da Capo Resources Ltd. and Granges, Inc. amalgamated under the name “Vista Gold Corp.” and, effective December 1997, Vista continued from the Province of British Columbia to the Yukon Territory, Canada under the Business Corporations Act (Yukon Territory). On June 11, 2013, Vista continued from the Yukon Territory, Canada to the Province of British Columbia, Canada under the Business Corporations Act (British Columbia). The current addresses, telephone and facsimile numbers of our offices are: Executive Office 7961 Shaffer Parkway, Suite 5 Littleton, Colorado, USA 80127 Telephone: (720) 981-1185 Facsimile: (720) 981-1186 Registered and Records Office 1200 Waterfront Centre – 200 Burrard Street Vancouver, British Columbia, Canada V7X 1T2 Telephone: (604) 687-5744 Facsimile: (604) 687-1415 Human Capital Management As of December 31, 2022, we had 14 full-time and no part-time employees globally. In addition, we use consultants with specific skills to assist with various aspects of our corporate affairs, project evaluation, due diligence, corporate governance and property management. Our compensation programs are designed to align compensation of our employees with Vista’s corporate objectives and performance, and are designed to provide proper incentives to attract, retain and motivate employees to achieve superior 3 results. The structure of our compensation programs balances competitive wages, benefits and incentive earnings for both short-term and long-term performance. The health and safety of our employees and others is a high priority in the way we manage our business. Oversight is provided by the Company’s board of directors (the “Board of Directors”) through the Health, Safety, Environment and Social Responsibility Committee. Management utilizes the principles set out in our Health & Safety Policy to administer health and safety programs. Employees and others entering our workplaces are provided with and required to use personal protective equipment appropriate for their duties. Each employee and visitor to our workplaces receives relevant orientation and is required to adhere to our established site health and safety protocols. In addition to recurring health and safety considerations, we comply with relevant policy and regulation recommended by government and health agencies in the jurisdictions where we operate. Our compensation programs also include consideration of health and safety performance in determining incentive awards. Vista’s priority to maintain a culture of ethical performance as a core value is reflected in the Company’s Code of Business Conduct and Ethics and other related policies. Oversight is provided by the Board of Directors and, for specific areas of performance, by committees of the Board of Directors. Employees are required to review the Code of Business Conduct and Ethics and acknowledge their understanding of the content and intent to comply on a periodic basis. Our compensation programs also include consideration of ethical performance in determining incentive awards. Vista values the diversity and talents of its team, collectively working together in an inclusive environment to achieve corporate goals and personal and professional development objectives. We cultivate a culture that is sensitive to the importance of diversity and inclusion in the workplace and are committed to continuous improvement in these areas. Environmental, Social, and Governance Responsibility Vista is committed to implementing and continuing to improve business practices that are designed to mitigate environmental impacts of our operating activities, support the people and communities within our areas of influence, and appropriately manage the business affairs of our organization. We believe part of being a good corporate citizen requires a dedicated focus on how we affect the environment and fulfill our responsibilities to stakeholders. In particular, through our planning for development of Mt Todd, we have worked closely with governmental entities in the NT and local groups, including the Jawoyn Association Aboriginal Corporation (the “Jawoyn Association”), to strive towards an environmentally sound and socially responsible development plan. Segment Information We have one reportable segment, consisting of acquisition, exploration and evaluation activities which are focused on Australia. We acquire, explore, evaluate and advance gold exploration and potential development projects, which may lead to gold production or value adding strategic transactions such as earn-in right agreements, option agreements, leases to third parties, joint venture arrangements, or outright sales of assets. We reported no mining operating revenues during the years ended December 31, 2022 and 2021. Geographic location of mineral properties and plant and equipment is provided in Note 4 – Mineral Properties and Note 5 – Plant and Equipment to our Consolidated Financial Statements under the section heading “Item 8. Financial Statements and Supplementary Data” below. Reclamation The Mt Todd site was not reclaimed by the predecessor owners when the mine closed in 2000. Reclamation obligations associated with this period and prior to Vista’s acquisition in 2006 are presently the responsibility of the NT Government. After we provide notice to the NT Government that we intend to proceed with development, the Company will then assume these historical rehabilitation liabilities, currently stated by the NT Government at A$73 million. As a result, we will be required to mitigate long-term environmental impacts, including any of those existing prior to 2006, that are not otherwise mitigated during the mine life, by stabilizing, contouring, re-sloping and re-vegetating various portions of the Project after mining and mineral processing operations are completed. Reclamation programs will be conducted in accordance with detailed plans, which will be finalized and reviewed by the appropriate regulatory agencies at the time of the execution of the programs. 4 Government Regulation Our exploration and development activities and other property interests are subject to various national, state, territorial, provincial, and local laws and regulations in Australia and other jurisdictions, which govern prospecting, development, mining, mine safety, production, exports, taxes, labor standards, occupational health, waste disposal, protection of the environment, the use and disposal of hazardous substances, and other matters. We have obtained all major authorizations for Mt Todd and have pending applications for other minor licenses, permits or other authorizations currently required to conduct our exploration, development, and other programs. We believe we comply in all material respects with applicable mining, health, safety and environmental statutes and regulations in all of the jurisdictions in which we operate. Australian Laws Mineral projects in the NT are subject to Australian federal and NT laws and regulations regarding environmental matters and the use and disposal of hazardous wastes and materials. As with all mining projects, development and operation of Mt Todd is expected to have a variety of environmental impacts. In Australia, environmental legislation plays a significant role in the mining industry. We are required under Australian laws and regulations (federal and territorial) to acquire permits and other authorizations before Mt Todd can be developed and mined. In September 2014, the environmental impact statement (“EIS”) for Mt Todd was approved. The Environmental Protection Agency of the Northern Territory Government (“NT EPA”) advised that it had assessed the environmental impacts of the proposed gold mine at Mt Todd and authorized the Company to proceed with development, subject to a number of recommendations as outlined in the assessment report (the “Assessment Report”). The Assessment Report included a request for Vista to secure an authorization under the federal Environmental Protection and Biodiversity Conservation Act 1999 (“EPBC”) as it relates to the Gouldian Finch. In January 2018, the authorization required by the EPBC was approved by the Australia Department of the Environment and Energy. We must comply with the terms of our Authority Certificate under the Northern Territory Aboriginal Sacred Sites Act 1989 which deals with the handling of archeological material and sacred sites. We are also subject to statutory requirements under the Mining Management Act, which includes the requirement to receive authorization of an MMP before the start of mining operations. The MMP was approved by the Northern Territory Department of Industry, Tourism and Trade (“DITT”) in June 2021 and is currently being amended to align with the larger- scale design in the Mt Todd FS. The changes to the waste rock dump design have been referred to the NT EPA as required under the Environmental Protection Act 2019 for its consideration. Environmental Regulation Mt Todd is subject to various federal, territorial, and local laws and regulations governing protection of the environment. Such laws and regulations are continually changing and, in general, are becoming more restrictive. Our policy is to conduct business in a way that safeguards public health and the environment. We believe that our operations are conducted in material compliance with applicable laws and regulations. Changes to current local, territorial, or federal laws and regulations in the jurisdictions where we have exploration and development activities could require additional capital expenditures and increase operating and/or reclamation costs. We are unable to predict what additional legislation, if any, might be proposed or enacted, or what additional regulatory requirements could impact the economics of Mt Todd. During 2022, Mt Todd did not have any material non-compliance occurrences with any applicable environmental laws and regulations. See “Item 1. Business – Reclamation”, above. Competition We compete with other mining companies to acquire, explore, finance, and develop gold properties and to retain expert consultants required to complete our geological and project development studies. We also compete with other mining companies to hire mining engineers, geologists and other skilled personnel in the mining industry, and for exploration and development services. Some of these competing mining companies have substantially greater financial and technical resources than Vista. As a result, we may have difficulty acquiring attractive gold projects at reasonable prices, engaging 5 skilled consultants with sufficient resources to support timely completion of work programs, and attracting and retaining qualified personnel. Gold Price History The price of gold is volatile and is affected by numerous factors, all of which are beyond our control, such as the sale or purchase of gold by various central banks and financial institutions, inflation, recession, fluctuation in the relative values of the U.S. dollar to foreign currencies, changes in global gold supply and demand, and political and economic conditions. The following table presents the high, low and average London Bullion Market Association PM Fix prices in U.S. dollars per troy ounce of gold over the past five years and during 2023 through February 14, 2023: Year 2018 2019 2020 2021 2022 2023 (to February 14, 2023) High 1,355 $ 1,546 $ 2,067 $ 1,943 $ 2,039 $ 1,932 $ $ $ $ $ $ $ Low 1,178 $ 1,270 $ 1,474 $ 1,684 $ 1,629 $ 1,834 $ 1,269 1,393 1,770 1,799 1,800 1,893 Average Data Source: www.lbma.org.uk/prices-and-data/precious-metal-prices#/ Available Information We make available, without charge, on or through our website at www.vistagold.com, our annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and any amendments to those reports filed or furnished pursuant to Sections 13(a) or 15(d) of the Exchange Act.

Metric Conversion Table To Convert Metric Measurement Units Hectares Meters Kilometers Tonnes Liters Grams Grams per tonne Glossary of Selected Mining Terms To Imperial Measurement Units Multiply by 2.4710 Acres 3.2808 Feet 0.6214 Miles 1.1023 Tons (short) 0.2642 Gallons 0.0322 Ounces (troy) 0.0292 Ounces (troy) per ton (short) “bedding” means the characteristic structure of sedimentary rock in which layers of different composition, grain size or arrangement are layered one on top of another in a sequence with oldest on the bottom and youngest at the top. “comminution” means the process in which ore is broken into small fragments by crushing, grinding, and other processes. “conglomerate” refers to clastic sedimentary rock that contains rounded particles that are greater than two millimeters in diameter. The space between the pebbles is generally filled with smaller particles and/or a chemical cement that binds the rock together. “cut-off grade” means the grade (i.e., the concentration of metal or mineral in rock) that determines whether mined mineralized material will be processed or considered waste. 6 “deposit” is an informal term for an accumulation of mineralized material. “development stage issuer” is an issuer that is engaged in the preparation of mineral reserves for extraction on at least one material property. “development stage property” is a property that has mineral reserves disclosed, pursuant to S-K 1300, but no material extraction. “feasibility study” is a comprehensive technical and economic study of the selected development option for a mineral project that includes appropriately detailed assessments of realistically assumed mining, processing, metallurgical, economic, marketing, legal, environmental, social and governmental considerations together with any other relevant operational factors and detailed financial analysis that are necessary to demonstrate at the time of reporting that extraction is reasonably justified or economically viable. The results of a feasibility study may reasonably serve as the basis for a final decision by a proponent or financial institution to proceed with, or finance, the development of a project. The confidence level of a feasibility study is higher than that of a preliminary feasibility study. “g Au/t” means grams of gold per tonne. “geosyncline” means a major trough or downwarp of the Earth’s crust, in which great thicknesses of sedimentary and/or volcanic rocks have accumulated. “indicated mineral resource” and “indicated resource” mean “indicated mineral resource” defined by S-K 1300 as that part of a mineral resource for which quantity and grade or quality are estimated 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 evaluation 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 be converted only to a probable mineral reserve. “inferred mineral resource” and “inferred resource” mean “inferred mineral resource” defined by S-K 1300 as that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. 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 extraction in a manner useful for evaluation of economic viability. Because an inferred mineral resource has the lowest level of geological confidence of all mineral resources, which prevents the application of modifying factors in a manner useful for evaluation 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. “measured mineral resource” and “measured resource” mean “measured mineral resource” defined by S-K 1300 as that part of a mineral resource for which quantity and grade or quality are estimated 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 in sufficient detail to support detailed mine planning and final evaluation 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. “mineral reserve” is 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. “mineral resource” is 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, 7 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. “ore” means material containing minerals in such quantity, grade and chemical composition that they can be economically extracted. “ore sorting” means technology that separates “ore” and “waste” based on physical and/or chemical properties of the material being sorted. “oxide” means mineralized rock in which some of the original minerals have been oxidized (i.e., combined with oxygen). Oxidation tends to make the rock more porous and permits a more complete permeation of cyanide solutions so that minute particles of gold in the interior of the minerals will be more readily dissolved. “probable mineral reserves” under S-K 1300 is the economically mineable part of an indicated and, in some cases, a measured mineral resource. “proven mineral reserves” under S-K 1300 is the economically mineable part of a measured mineral resource and can only result from conversion of a measured mineral resource. “qualified person” or “QP” as defined under S-K 1300 is an individual who is: (1) a mineral industry professional with at least five years of relevant experience in the type of mineralization and type of deposit under consideration and in the specific type of activity that person is undertaking on behalf of the registrant; and (2) an eligible member or licensee in good standing of a recognized professional organization at the time the technical report is prepared. For an organization to be a recognized professional organization, it must: (i) be either: (A) an organization recognized within the mining industry as a reputable professional association; or (B) a board authorized by U.S. federal, state or foreign statute to regulate professionals in the mining, geoscience or related field; (ii) admit eligible members primarily on the basis of their academic qualifications and experience; (iii) establish and require compliance with professional standards of competence and ethics; (iv) require or encourage continuing professional development; (v) have and apply disciplinary powers, including the power to suspend or expel a member regardless of where the member practices or resides; and (vi) provide a public list of members in good standing. “qualified person” or “QP” as defined under NI 43-101 means an individual who (1) is an engineer or geoscientist with a university degree, or equivalent accreditation, in an area of geoscience, or engineering, relating to mineral exploration or mining; (2) has at least five years of experience in mineral exploration, mine development or operation, or mineral project assessment or any combination of these that is relevant to his or her professional degree or area of practice; (3) has experience relevant to the subject matter of the mineral project and the technical report; (4) is in good standing with a professional association; and (5) in the case of a professional association in a foreign jurisdiction, has a membership designation that (i) requires attainment of a position of responsibility in their profession that requires the exercise of independent judgment; and (ii) requires (A) a favorable, confidential peer evaluation of the individual’s character, professional judgment, expertise and ethical fitness; or (B) a recommendation for membership by at least two peers, and demonstrated prominence or expertise in the field of mineral exploration or mining. Note: a professional association is a self-regulatory organization of engineers, geoscientists or both that, among other criteria, requires compliance with the professional standards of competence and ethics established by the organization and has disciplinary powers over its members. “recovery” means that portion of the metal contained in the ore that is successfully extracted by processing and is expressed as a percentage. “sampling” means selecting a fractional, but representative, part of a mineral deposit for analysis. “strike” when used as a noun, means the direction, course or bearing of a vein or rock formation measured on a level surface and, when used as a verb, means to take such direction, course or bearing. 8 “sulfide” means a compound of sulfur and some other element. From a metallurgical perspective, sulfide rock is primary rock that has not been oxidized. Both ore and waste may contain sulfide minerals. “tpd” means tonnes per day. “vein” means a fissure, fault or crack in a rock filled by minerals that have traveled upwards from some deep source. “waste” means rock lacking sufficient grade and/or other characteristics of ore. Cautionary Note to Investors Regarding Estimates of Measured, Indicated and Inferred Resources and Proven and Probable Mineral Reserves We are subject to the reporting requirements of the Exchange Act and applicable Canadian securities laws, and as a result we report our mineral reserves and mineral resources according to two different standards. For U.S. purposes, mineral property disclosures are reported in accordance with S-K 1300 under the Exchange Act, while Canadian disclosures are reported in accordance with Canadian National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43- 101”). Both sets of reporting standards have similar goals in terms of conveying an appropriate level of confidence in the disclosures being reported, but the standards embody slightly different approaches and definitions. In our public filings in the U.S. and Canada and in certain other announcements not filed with the U.S. Securities Exchange Commission (“SEC”), we disclose proven and probable reserves and measured, indicated, and inferred resources, each as defined in S-K 1300 and NI 43-101. As currently reported, there are no material differences in our disclosed proven and probable reserves and measured, indicated, and inferred resource under each of S-K 1300 and NI 43-101. The estimation of measured resources and indicated resources involve greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable reserves; therefore, investors are cautioned not to assume that all or any part of measured or indicated resources will ever be converted into S-K 1300-compliant or NI 43-101-compliant reserves. Estimations of inferred resources involve far greater uncertainty as to their existence and economic viability than the estimations of other categories of resources; therefore, it cannot be assumed that all or any part of inferred resources will ever be upgraded to a higher category. Investors are cautioned not to assume that all or any part of inferred resources exist, or that they can be mined legally or economically. Note Regarding Forward-Looking Statements This annual report, including all exhibits hereto and any documents that are incorporated by reference as set forth on the face page under “Documents incorporated by reference”, contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 and forward-looking information under Canadian securities laws that are intended to be covered by the safe harbor created by such legislation. All statements, other than statements of historical facts, included in this annual report on Form 10-K, our other filings with the SEC and Canadian securities commissions and in press releases and public statements by our officers or representatives that address activities, events, or developments that we expect or anticipate will or may occur in the future are forward-looking statements and forward- looking information, including, but not limited to, those listed below: Operations • • • our belief that the Mt Todd FS has added substantial value to the Project and positions the Project for near-term development; our belief that our investments to systematically explore, evaluate, engineer, permit and de-risk the Project have added to the underlying value of the Project and demonstrate strong development potential; our plans and available funding to continue to identify and study potential Mt Todd optimizations, project improvements and efficiencies; • our expectation that completion of a smaller scale project study is expected in the first quarter of 2023; 9 • • • • • • • • • • • • • • • • • • • • • • • • the results of the Mt Todd FS and its related estimates and projections, including projected free cash flow, future exchange rates and commodity prices; our belief that there are indications that market conditions are improving; our expectation to be able to demonstrate an attractive alternate development strategy early in 2023; our belief that the results from our exploration drilling program and historical sources demonstrate excellent resource growth potential; our belief that an alternate development strategy will attract the interest of new potential partners and those who have previously expressed interest in different development strategies; our belief that certain exploration targets represent the closest and most immediate opportunity for growth with the appropriate investment in additional drilling; the feasibility of Mt Todd and the results of the Mt Todd FS; our belief that fine grinding will improve gold recoveries and favorably impact project economics; estimates of future operating and financial performance; future exploration plans; our expectation of Mt Todd’s impact, including environmental and economic impacts; plans and estimates concerning potential Mt Todd development, including access to an adequate supply of water, the availability of natural gas on acceptable terms, as well as the ability to obtain all required permits; our expectation that dewatering of the pit will not present any major issues when resuming operations in the Batman pit; estimates of mineral reserves and mineral resources; our intention to improve the value of our gold projects; the potential that development projects may lead to gold production or value-adding strategic transactions; our belief that we are in compliance in all material respects with applicable mining, health, safety and environmental statutes and regulations in all of the jurisdictions in which we operate and that our operations are conducted in material compliance with applicable laws and regulations; our belief that our investment of significant resources in water treatment and management, environmental, and social programs has benefited our relationships with the traditional landowners, local communities, and NT Government, creating a strong social license; our expectation that a community-based project would produce lower operating costs compared to contract mining and that a portion of the skilled workforce should be able to be sourced locally; our expectation that the remaining permitting processes are relatively straight-forward and are not expected to impede, to a material extent, our exploration and future development plans; our estimates with respect to historical mine production at Mt Todd; our expectation that plus 5/8” high pressure grinding roll (“HPGR”) crusher product at Mt Todd is harder than the minus 5/8” crushed product and that the hardness of ore in the Batman deposit is relatively consistent; our expectation that the use of HPGR crushers at Mt Todd will produce a product that can be ground more efficiently and reduce energy requirements as compared to a SAG Mill design; the expectation that reclamation of the heap leach pad at Mt Todd will include disposal of pad liner and regrading of the area occupied by the heap leach pad only as the material on the existing heap leach pad will be processed through the mill at the end of mine life; and 10 • our expectation that existing infrastructure at Mt Todd will reduce initial capital expenditure and significantly reduce capital risk related to infrastructure construction. Business and Industry • Our expectation that existing working capital as of December 31, 2022, together with other potential future sources of non-dilutive financing, will be sufficient to fully fund our currently planned corporate expenses, Project holding costs and discretionary programs for at least one year from the date of issuance of this annual report on Form 10-K; • • • • • • • • • • • our belief that the ATM Program (as defined below) will provide additional financing flexibility at a low cost; the potential monetization of our non-core assets, including a royalty interest in the U.S. and our used mill equipment which is for sale; potential expenditures, funding requirements and sources of capital, including near-term sources of additional cash; our expectation that the Company will continue to incur losses and will not pay dividends for the foreseeable future; our belief that the current market value of the Common Shares does not reflect the fair value of the Company’s assets; our belief that we maintain reasonable amounts of insurance; our expectations related to potential changes in regulations or taxation initiatives; our expectation that we will continue to be a passive foreign investment company; the potential that we may grant options and/or other stock-based awards to our directors, officers, employees and consultants; preliminary estimates of the reclamation and other related costs that would be incurred if we were to notify the NT Government that we intend to proceed with development and assume rehabilitation liability for Mt Todd; and the potential that future expenditures may be required for compliance with various laws and regulations governing the protection of the environment.

Financial and Business Risks fluctuations in the price of gold; inflation and cost escalation; lack of adequate insurance to cover potential liabilities; the lack of cash dividend payments by us; our history of losses from operations; our ability to attract, retain and hire key personnel; volatility in our stock price and gold equities generally; our ability to obtain a development partner or other means of financing for Mt Todd on favorable terms, if at all; our ability to raise additional capital or raise funds from the sale of non-core assets on favorable terms, if at all; general economic conditions adverse to Mt Todd development or operation; 12 • • • • • • • • • • • • • • • • the potential acquisition of a control position in the Company for less than fair value as a result of industry consolidation or otherwise; lack of success in our efforts to find an acceptable partner, external financing or other acceptable alternatives to move forward with development of Mt Todd; evolving corporate governance and public disclosure regulations; intense competition in the mining industry; tax initiatives on domestic and international levels; potential changes in regulations of taxation initiatives; fluctuation in foreign currency values; our likely status as a PFIC (as defined below) for U.S. federal tax purposes; cybersecurity breaches that threaten or disrupt our information technology systems; anti-bribery and anti-corruption laws; and potential conflicts of interest arising from certain of our directors and officers serving as directors and officers of other companies in the natural resources sector. Industry Risks inherent hazards of mining exploration, development and operating activities; a shortage of skilled labor, equipment and supplies; the accuracy of calculations of mineral reserves and mineral resources and mineralized material and fluctuations therein based on metal prices, estimated costs, and inherent vulnerability of the ore and recoverability of metal in the mining process; changes in environmental regulations to which our exploration and development operations are subject could result in increased operating costs or our ability to operate at all; and changes in greenhouse gas emissions regulations and standards could result in increased operating costs or our ability to operate at all. For a more detailed discussion of such risks and other important factors that could cause actual results to differ materially from those in such forward-looking statements and forward-looking information, please see “Item 1A. Risk Factors” below in this annual report on Form 10-K. Although we have attempted to identify important factors that could cause actual results to differ materially from those described in forward-looking statements and forward-looking information, there may be other factors that cause results to be materially different than anticipated, estimated or intended. There can be no assurance that these forward-looking statements will prove to be accurate as actual results and future events could differ materially from those anticipated in the statements. Except as required by law, we assume no obligation to publicly update any forward-looking statements and forward-looking information, whether as a result of new information, future events or otherwise. ITEM 1A. RISK FACTORS. An investment in our securities involves a high degree of risk. The risks described below are not the only ones facing the Company or otherwise associated with an investment in our securities. Additional risks not presently known to us or which we currently consider not material may also adversely affect our business. If any of the following risks actually occur, our business, financial condition and operating results could be materially adversely affected. 13 Operating Risks We cannot be assured that the Mt Todd FS has, or future studies will, accurately forecast economic results. Mt Todd is our principal asset. Our ability to arrange financing to develop Mt Todd and our future profitability depend on the economic and technical feasibility of the Project as established through formal feasibility studies, such as the Mt Todd FS. There can be no assurance that the mining, comminution, and gold recovery processes (including ore sorting), gold production rates, revenue, and capital and operating costs including taxes and royalties will not vary unfavorably from the estimates and assumptions included in the Mt Todd FS, or any future studies. Mt Todd requires substantial capital investment, and we may be unable to raise sufficient capital on favorable terms or at all. Ongoing site costs, construction, operation and reclamation of Mt Todd will require significant capital. Our ability to raise sufficient capital and/or secure a development partner or other form of transaction on satisfactory terms, if at all, will depend on several factors, including the Mt Todd FS or any future studies, applicable laws and regulations, acquisition of the requisite permits, macroeconomic conditions, and future gold prices. Uncontrollable factors or other factors such as lower gold prices, unanticipated operating or permitting challenges, inability to secure a development partner or other form of transaction, actual and perceived environmental impacts, or illiquidity in the debt or equity markets, including the cost of capital and other conditions of financing arrangements that impose restrictive covenants and security interests that may affect the Company’s ability to operate as intended and ultimately its ability to continue as a going concern, could impede our ability to finance ongoing and future activities at Mt Todd on acceptable terms, or at all. If we decide to construct the mine at Mt Todd, we will assume substantial reclamation obligations resulting in a material financial obligation. The Mt Todd site was not reclaimed when the original mine closed. Although we are not currently responsible for the reclamation of these historical disturbances, we will accept full responsibility for them if and when we make a decision to finance and construct the mine and provide notice to the NT Government of our intention to take over and assume the management, operation and rehabilitation of Mt Todd. At such time, we will be required to provide a bond or other surety in a form and amount satisfactory to the NT Government that would cover the prospective expense to reclaim the Mt Todd property. In addition, the regulatory authorities may increase reclamation and bonding requirements from time to time. The satisfaction of these bonding requirements and continuing or future reclamation obligations will require a significant amount of capital. There is no assurance that we will be able to provide an acceptable form of bond or other surety, or provide sufficient working capital to complete any required rehabilitation if and when such obligations are assumed by the Company. There may be delays in the construction of Mt Todd. Delays in commencing and completing construction could result from factors such as availability and performance of engineering and construction contractors, suppliers, consultants, and employees; availability of required equipment; delays in receiving any required approvals and authorizations; and availability of capital. Any delay in performance by any one or more of the contractors, suppliers, consultants, employees or other persons on which we depend, or lack of availability of required equipment, or delay or failure to receive required governmental approvals or financing could delay, prevent commencement of, or interrupt construction at Mt Todd. There can be no assurance of whether or when construction at Mt Todd will start, the duration of the construction period, or that the necessary personnel, equipment, supplies, or other resources will be available to the Company if and when construction is started. Increased costs could impede our ability to become profitable. Capital and operating costs at mining operations are subject to variation due to a number of factors, such as changing ore grade, changing metallurgy, and revisions to mine plans in response to changing commodity prices, additional drilling results and updated geologic interpretations. In addition, costs are affected by the cost of capital, tax and royalty regimes, 14 trade tariffs, the global cost of mining and processing equipment, commodity prices, and foreign exchange rates, as well as the costs of fuel, electricity, operating supplies, and appropriately skilled labor. These costs are at times subject to volatile price movements, including increases that could make future development and production at Mt Todd less profitable or uneconomic. This could have a material adverse effect on our business prospects, results of operations, cash flows and financial condition. We cannot be assured that we will have an adequate water supply for mining operations at Mt Todd. Water at Mt Todd is expected to be provided from a freshwater reservoir that is fed by seasonal rains. Insufficient rainfall, or drought-like conditions in the area feeding the reservoir could limit or extinguish this water supply. Sufficient water resources may not be available, resulting in curtailment or stoppage of operations until the water supply is replenished. This could have a material adverse effect on our business prospects, results of operations, cash flows and financial condition. We rely on third parties to fulfill their obligations under agreements. Our business strategy includes entering into agreements with third parties (“Third Parties”). Such Third Parties may: (i) have economic or business interests or goals that are inconsistent with or opposed to ours; (ii) have rights in conflict with what we believe to be in our best interests; (iii) take action contrary to our policies or objectives; or (iv) as a result of financial or other reasons, be unable or unwilling to fulfill their obligations under the agreement(s). Any one or a combination of these could result in liabilities for us and/or could adversely affect the value of the related project(s) and, by association, damage our reputation and consequently our ability to acquire or advance other projects and/or attract future Third Parties. Our exploration and development interests are subject to evolving environmental regulations. Our property and royalty interests are subject to environmental regulations. Environmental legislation is becoming more restrictive, with 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. There is no assurance that future changes in environmental laws and regulations will not adversely affect our interests. Currently, our property and royalty interests are subject to environmental laws and regulations in Australia and the U.S. We could be subject to environmental lawsuits. Neighboring landowners and other third parties could file claims based on environmental statutes and common law for personal injury and property damage allegedly caused by environmental nuisance, the release of hazardous substances or other waste material into the environment on or around our properties. There can be no assurance that our defense of such claims would be successful. This could have a material adverse effect on our business prospects, results of operation, cash flows, financial condition, and corporate reputation. We may have material undisclosed environmental liabilities of which we are not aware. Vista has been engaged in gold exploration since 1983. Since inception, the Company has been involved in numerous exploration projects in many jurisdictions. There may be environmental liabilities associated with disturbances at these projects for which the Company may be identified as a responsible or potentially responsible party, regardless of its level of involvement in creating the related disturbance. We may not be aware of such claims against the Company until regulators provide notice thereof. Consequently, we may have material undisclosed environmental responsibilities which could negatively affect our business prospects, results of operations, cash flows, financial condition, and corporate reputation. 15 There may be challenges to our title to mineral properties. There may be challenges to our title to our mineral properties. If there are title defects with respect to any of our properties, we may be required to compensate other persons or reduce or lose our interest in the affected property. In any such case, the investigation and resolution of title issues could divert Company resources from our core strategies. Opposition to Mt Todd could have a material adverse effect. There is generally an increasing level of public concern relating to extractive industries. Opposition to extractive industries, or our development and operating plans at Mt Todd specifically, could have adverse effects on our reputation and support from other stakeholders. As a result, we may be unable to secure adequate financing or complete other activities necessary to continue our planned activities. Any resulting delays or an inability to develop and operate Mt Todd as planned could have a material adverse effect on our business prospects, results of operations, cash flows, financial condition and corporate reputation. Our exploration and development activities, strategic transactions, or any acquisition activities may not be commercially successful and could fail to lead to gold production or fail to add value. Substantial expenditures are required to acquire gold properties, establish mineral reserves through drilling and analysis, develop metallurgical processes to extract metal from the ore and develop the mining and processing facilities and infrastructure at any site chosen for mining. We cannot be assured that any such activities will be commercially successful, lead to gold production, or add value. Financial and Business Risks We have a history of losses, and we do not expect to generate earnings from operations or pay dividends in the near term, if at all. We are a development stage issuer, and we devote our efforts to our development stage property, Mt Todd. We do not currently produce gold and do not currently generate operating earnings from gold production. We finance our business activities principally by issuing equity. We have incurred losses in all annual periods since 1998, except for the years ended December 31, 2011, during which we recorded non-cash net gains, December 31, 2015 during which we recorded gains related to research and development refunds, and December 31, 2020 during which we monetized certain mineral property interests. We expect to continue to incur losses. We have no history of paying cash dividends and we do not expect to be able to pay cash dividends or to make any similar distribution of cash or other assets in the foreseeable future, if at all. A substantial or extended decline in gold prices would have a material adverse effect on the value of our assets and on our ability to raise capital and could result in lower than estimated economic returns. The value of our assets, our ability to raise capital and our future economic returns are substantially dependent on the price of gold. The gold price is volatile and is affected by numerous factors beyond our control. Factors tending to influence gold prices include: • • • • • • • gold sales or leasing by governments and central banks or changes in their monetary policy, including gold inventory management and reallocation of reserves; speculative short or long positions on futures markets; the relative strength of the U.S. dollar; current, or expectations of future, rates of inflation or interest rates; changes to economic conditions in the United States, China, India and other industrialized or developing countries; geopolitical conflicts; changes in jewelry, investment or industrial demand; 16 • • changes in supply from production, disinvestment, and scrap; and forward sales by producers in hedging or similar transactions. A substantial or extended decline in the gold price could: • • • • • • • negatively impact our ability to raise capital on favorable terms, or at all; negatively affect our ability to find a partner, investor or lender for the development of Mt Todd; jeopardize the development of Mt Todd; reduce our existing estimated mineral resources and reserves by removing material from these estimates that could not be economically processed at lower gold prices; reduce the potential for future revenues from gold projects in which we have an interest; reduce funds available to operate our business; and reduce the market value of the common shares in the capital of the Company (the “Common Shares”) and our assets. Industry consolidation could result in the acquisition of a control position in the Company for less than fair value. Consolidation within the industry is a growing trend. As a result of the broad range of market and industry factors including the price of gold, we believe the current market value of the Common Shares does not reflect the fair value of the Company’s assets. These conditions could result in the acquisition of a control position, or attempted acquisition of a control position in the Company at what we believe to be less than fair value. This could result in substantial costs to us and divert our management’s attention and resources. A completed acquisition could result in realized losses for shareholders of the Company. We may be unable to raise additional capital on favorable terms, or at all. Our exploration and, if warranted, development activities and the construction and start-up of any mining operation require substantial amounts of capital. To develop Mt Todd, acquire attractive gold or other projects, and/or continue our business, we will have to secure a development partner or otherwise source sufficient equity, debt or other forms of capital, raise additional funds from the sale of non-core assets and / or seek additional sources of capital from other external sources. There can be no assurance that we will be successful in securing a development partner or otherwise raising additional capital on acceptable terms, including the cost of such capital and other conditions of financing arrangements that impose restrictive covenants and security interests that may affect the Company’s ability to operate as intended and ultimately its ability to continue as a going concern. If we cannot raise sufficient additional capital, we may be required to substantially reduce or cease operations, any of which may affect our ability to continue as a going concern. We face intense competition in the mining industry. The mining industry is intensely competitive in all its phases. Some of our competitors are much larger, established companies with greater financial and technical resources than ours. We compete with other companies for attractive mining properties, for capital, for equipment and supplies, for outside services and for qualified managerial and technical employees. Access to financing, equipment, supplies, skilled labor, and other resources may also be affected by competition from non-mining related commercial sectors. If we are unable to raise sufficient capital, we will be unable to execute exploration and development programs, or such programs may be reduced in scope. Competition for equipment and supplies could result in shortages of necessary supplies and/or increased costs. Competition for outside services could result in increased costs, reduced quality of service and/or delays in completing services. If we cannot successfully retain or attract qualified employees, our ability to advance the development of Mt Todd, to attract necessary financing, to meet all our environmental and regulatory responsibilities, or to take opportunities to improve our business, could be negatively affected. This could have a material adverse effect on our business prospects, results of operations, cash flows and financial condition. 17 The occurrence of events for which we are not insured may affect our cash flow and overall profitability. We maintain insurance policies that mitigate certain risks related to our assets and business activities. This insurance is maintained in amounts that we believe to be reasonable based on the circumstances surrounding each identified risk. However, we may elect to limit or not have insurance for certain risks because of the high premiums associated with insuring those risks or for various other reasons. In other cases, insurance may not be available for certain risks. We do not insure against political risk. The occurrence of events for which we are not insured adequately, or at all, could result in significant losses that could materially adversely affect our financial condition and our ability to fund our business. Currency fluctuations may adversely affect our costs. We have material property interests in Australia. Most costs in Australia are incurred in the local currency. Appreciation of the Australian dollar, if any, against the U.S. dollar effectively increases our cost of doing business. This could have the effect of increasing the amount of capital required to continue to maintain, explore and develop Mt Todd, reducing the pace at which it is explored and developed, and/or cause activities to be suspended either temporarily or permanently. The Company is likely a “passive foreign investment company,” which will likely have adverse U.S. federal income tax consequences for U.S. shareholders. U.S. shareholders of our Common Shares should be aware that the Company believes it was classified as a passive foreign investment company (“PFIC”) up to and including the taxable year ended December 31, 2022, and based on current business plans and financial projections, management believes there is a significant likelihood that the Company will be classified as a PFIC during the current taxable year. If the Company is classified as a PFIC for any year during a U.S. shareholder’s holding period, then such U.S. shareholder generally will be required to treat any gain realized upon a disposition of Common Shares, or any so-called “excess distribution” received on their Common Shares, as ordinary income, and to pay an interest charge on a portion of such gain or distributions, unless the shareholder makes a timely and effective “qualified electing fund” (“QEF Election”) or a “mark-to-market” election with respect to the Common Shares. A U.S. shareholder who makes a QEF Election generally must report on a current basis its share of the net capital gain and ordinary earnings for any year in which the Company is PFIC, whether or not the Company distributes any amounts to its shareholders. U.S. shareholders should be aware that there can be no assurance that the Company will satisfy record keeping requirements that apply to a QEF Election, or that the Company will supply U.S. shareholders with information that such U.S. shareholders require to report under the QEF Election rules, in event that the Company is a PFIC and a U.S. shareholder wishes to make a QEF Election. Thus, U.S. shareholders may not be able to make a QEF Election with respect to their Common Shares. A U.S. shareholder who makes the mark-to-market election generally must include as ordinary income each year the excess of the fair market value of the Common Shares over the taxpayer’s basis therein. This paragraph is qualified in its entirety by the discussion below in “Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities - “Certain U.S. Federal Income Tax Considerations for U.S. Residents.” Each U.S. shareholder should consult his or her own tax advisor regarding the U.S. federal, U.S. state and local, and foreign tax consequences of the PFIC rules and the acquisition, ownership, and disposition of Common Shares. Certain directors and officers may serve as directors and officers of other companies in the natural resources sector. While there are no known existing or potential conflicts of interest between Vista and any of its directors or officers, certain of the directors and officers do or may serve as directors and officers of other natural resource companies and therefore it is possible that a conflict may arise between their duties as a director or officer of Vista and their duties as a director or officer of such other companies. The directors and officers of Vista are aware of the existence of laws governing accountability of directors and officers for corporate opportunity and disclosure of conflicts of interest. Should any director or officer breach the duties imposed upon them by applicable laws, such actions or inactions could have a material adverse effect on our business prospects, results of operations, cash flows, financial position, and corporate reputation. 18 Industry Risks Calculations of mineral resources and mineral reserves are estimates only and subject to uncertainty. Estimation of mineral resources and mineral reserves is an imprecise process and the accuracy of such estimates is a function of the quantity and quality of available data, assumptions used, and judgments made in interpreting geological information and estimating future capital and operating costs. There is significant uncertainty in mineral resources and mineral reserves estimates, and the economic results of mining a mineral deposit may differ materially from the estimates as additional data develops, interpretations change, or actual economic conditions vary from the estimates used. Estimated mineral resources and mineral reserves may be materially affected by other factors. In addition to uncertainties inherent in estimating mineral resources and mineral reserves, other factors may adversely affect estimated mineral resources and mineral reserves. Such factors may include but are not limited to metallurgical, environmental, permitting, legal, title, taxation, socio-economic, marketing, political, gold prices, and capital and operating costs. Any of these or other adverse factors may reduce or eliminate estimated mineral reserves and mineral resources and could have a material adverse effect on our business prospects, results of operations, cash flows, financial position, and corporate reputation. Feasibility studies and other technical studies are estimates only and subject to uncertainty. Feasibility studies, such as our Mt Todd FS, and other technical studies are used to estimate the economic viability of an ore deposit, as are preliminary feasibility studies, preliminary economic assessments, and scoping studies. Feasibility studies are the most detailed studies and reflect higher levels of confidence in estimated production rates, and capital and operating costs. Accepted levels of confidence required to meet the standards set out in S-K 1300 are plus or minus 15% for feasibility studies, plus or minus 25-30% for preliminary feasibility studies and plus or minus 35-40% for preliminary economic assessments. Confidence levels for scoping studies may vary, but generally provide less confidence than preliminary economic assessments. These thresholds reflect the levels of confidence that exist at the time the study is completed. Subsequent changes to metal prices, foreign exchange rates (if applicable), reclamation requirements, operating and capital costs, and other variables may cause actual results of economic viability to differ materially from these estimates. Results of any subsequent Mt Todd feasibility study may be less favorable than the current Mt Todd FS. Mining companies are increasingly required to consider and provide benefits to the communities, regions, and countries in which they operate, and are subject to extensive environmental, health and safety laws and regulations. As a result of public concern about the real or perceived detrimental effects of economic globalization, global climate impacts, and other adverse environmental effects resulting from the operation of extractive industries, businesses in general and the mining industry in particular face increasing public scrutiny of their activities. These businesses are under pressure to demonstrate that as they seek to generate satisfactory returns on investment to shareholders, other stakeholders, including employees, governments, Aboriginal peoples, communities surrounding operations, adjacent regions, and the countries in which they operate, such constituencies benefit and will continue to benefit from their commercial activities. The potential consequences of these pressures include reputational damage, delays, suspension of activities, legal claims, increased costs, increased social investment obligations, difficulty in acquiring permits, and increased taxes and royalties payable to governments and communities. Mining exploration, development and operating activities are inherently hazardous. Mineral exploration and development involve many risks that even a combination of experience, knowledge and careful evaluation may not be able to overcome. Operations in which we have direct or indirect interests will be subject to all the hazards and risks normally incidental to exploration, development, and production of gold and other metals, any of which could result in work stoppages, damage to property, physical harm and possible environmental damage. The nature of these risks is such that liabilities might exceed any liability insurance policy limits. It is also possible that the liabilities and hazards might not be insurable, or, we could elect not to be insured against such liabilities due to high premium costs or other reasons, or our insurance for a particular event or circumstance might be insufficient, in which event we could 19 incur significant costs that could have a material adverse effect on our business prospects, results of operations, cash flows, financial position, and corporate reputation. Pending or future legislation and regulations or other standards intended to address climate change could result in increased operating costs. Gold production is energy intensive, resulting in a significant carbon footprint. A number of governments, governmental bodies, the World Bank and/or other entities maintain, have introduced, or are contemplating laws, regulations and standards in response to the potential impact of climate change. This type of legislation and possible future legislation and increased regulation regarding climate change could impose significant costs related to increased energy requirements, capital equipment, environmental monitoring and reporting and other costs to comply with such regulations. Pending or future initiatives involving taxation could result in increased taxes and operating costs. There is growing attention from the media and the public on perceived international tax avoidance techniques which could result in escalating rates of poverty, inequality and unemployment in host countries. Initiatives like the Base Erosion and Profit Shifting project led by the Organization for Economic Cooperation and Development and specific country legislative measures, including Australia, aim to reform the system of international taxation to minimize international tax avoidance techniques. This initiative and possible future initiatives could result in increased tax expenses and related compliance costs for Mt Todd or other future mining operations. Securities Risks Our share price may be volatile and your investment in our Common Shares could suffer a decline in value. Broad market and industry factors may adversely affect the price of our Common Shares, regardless of our actual operating performance. Factors that could cause fluctuation in the price of our Common Shares may include, among other things: • • • • • • • • • • changes in financial estimates by us or by any securities analysts who might cover our stock market performance; stock market price and volume fluctuations of other publicly traded companies and, in particular, those that are in the mining industry; speculation about our business in the press or the investment community; conditions or trends in our industry or the economy generally; decreases in the prices of gold; announcements by us or our competitors of significant acquisitions, strategic partnerships or divestitures; inability to find a development partner, investor or lender on acceptable terms for the development of Mt Todd; additions or departures of key personnel; issuance of Common Shares by the Company; and sales of our Common Shares, including sales by our directors, officers, or significant stockholders. In the past, securities class action litigation has often been instituted against companies following periods of volatility in their stock price. This type of litigation or other securities claims could result in substantial costs to us and divert our management’s attention and resources. There may be limited liquidity for our Common Share warrants. There is no market through which our outstanding Common Share warrants may be sold. It is not possible to predict the price at which the warrants will trade in any secondary market or whether such market will be liquid or illiquid. To the extent warrants are exercised, the number of warrants outstanding will decrease, resulting in diminished liquidity for such remaining outstanding warrants. A decrease in the liquidity of the warrants may cause, in turn, an increase in the volatility associated with the price of the warrants. To the extent that the warrants become illiquid, an investor may have to exercise such warrants to realize value. 20 Potential dilution. Our constating documents allow us to issue an unlimited number of Common Shares for such consideration and on such terms and conditions as shall be established by the Board of Directors, in many cases, without the approval of shareholders. We may issue Common Shares in offerings from treasury (including through the sale of securities convertible into or exchangeable for Common Shares) and on the exercise of stock options or other securities exercisable for Common Shares. We cannot predict the size of future issuances of Common Shares or the effect that future issuances and sales of Common Shares will have on the market price of the Common Shares. Issuances of a substantial number of additional Common Shares, or the perception that such issuances could occur, may adversely affect prevailing market prices for the Common Shares. With any additional issuance of Common Shares, investors will suffer dilution to their shareholder interest and voting power. Holders of our Common Shares may not receive dividends. We have not historically declared cash dividends on our Common Shares. Holders of our Common Shares are entitled to receive only such dividends as our Board of Directors may declare out of funds legally available for such payments. Our ability to pay dividends will be subject to our future earnings, capital requirements and financial condition, as well as our compliance with covenants related to any future indebtedness and would only be declared in the discretion of our Board of Directors. The Company may experience cybersecurity breaches. General Risks Regular access to and security of information technology systems are critical to Vista’s operations. To Vista’s knowledge, it has not experienced any material losses relating to disruptions to its information technology systems. Vista has implemented policies, controls, and practices to manage and safeguard Vista and its stakeholders from internal and external cybersecurity threats and to comply with changing legal requirements and industry practice. Cyber risks cannot be fully mitigated, and these threats are continuing to evolve. Therefore, Vista cannot assure that its information technology systems are fully protected from cybercrime or that the systems will not be inadvertently compromised, or without failures or defects. Potential disruptions to Vista’s information technology systems, including, without limitation, security breaches, power loss, theft, computer viruses, cyber-attacks, natural disasters, and noncompliance by third party service providers and inadequate levels of cybersecurity expertise and safeguards of third party information technology service providers, may adversely affect the operations of Vista as well as present significant costs and risks including, without limitation, loss or disclosure of confidential, proprietary, personal or sensitive information and third party data, material adverse effect on its financial performance, compliance with its contractual obligations, compliance with applicable laws, damaged reputation, remediation costs, potential litigation, regulatory enforcement proceedings and heightened regulatory scrutiny. The Company is subject to anti-bribery and anti-corruption laws. Vista’s operations are governed by, and involve interactions with, many levels of government in several countries. Vista is required to comply with anti-corruption and anti-bribery laws in the countries in which we conduct our business. In recent years, there has been a general increase in both the frequency of enforcement and the severity of penalties under such laws, resulting in greater scrutiny and punishment to companies convicted of violating anti-corruption and anti- bribery laws. Furthermore, a company may be found liable for violations by not only its employees, but also by its contractors and third-party agents. Although we have adopted internal control policies to mitigate such risks, there can be no assurance that our internal control policies and procedures will always protect us from recklessness, fraudulent behavior, dishonesty or other inappropriate acts committed by our affiliates, employees or agents and such measures may not always be effective in ensuring that we, our employees, contractors or agents will comply strictly with such laws. If we find ourselves subject to an enforcement action or are found to be in violation of such laws, this could lead to civil and criminal fines and penalties, investigation and litigation, and loss of operating licenses or permits, resulting in a material adverse effect on our reputation and results of operations. 21 Our business is subject to evolving corporate governance and public disclosure regulations that have increased both our compliance costs and the risk of noncompliance. We are subject to changing rules and regulations promulgated by a number of governmental and self-regulated organizations, including but not limited to the British Columbia Securities Commission, the SEC, the Toronto Stock Exchange (the “TSX”), the NYSE American, and the Financial Accounting Standards Board. These rules and regulations continue to evolve in scope and complexity and many new requirements have been created in response to laws enacted by the United States Congress, making compliance increasingly more difficult and uncertain, which could have an adverse effect on our reputation and our stock price.

The following description of Mt Todd has been derived, in part, from the Mt Todd FS and readers should consult the Mt Todd FS to obtain further particulars regarding Mt Todd. The Mt Todd FS is available for review at www.sec.gov and under our profile at www.sedar.com. The Mt Todd FS is not incorporated by reference into this annual report on Form 10- K. Certain capitalized terms in this section not otherwise defined have the meanings ascribed to them in the Mt Todd FS. 23 Project Location and Access Mt Todd is located 56 kilometers by road northwest of Katherine, NT, Australia, and approximately 290 kilometers by road southeast of Darwin, NT. Access is by existing paved public roads and approximately four kilometers of paved private road. We control and maintain the private paved road. The area has a sub-tropical climate with a distinct wet season and dry season. The area receives most of its rainfall between the months of January and March. Temperatures are moderate, allowing for year-round mining operations. The topography is relatively flat. The tenements encompass a variety of habitats forming part of the northern Savannah woodland region, which is characterized by eucalypt woodland with tropical grass understories. Surface elevations are approximately 130 to 160 meters above sea level in the area of the previous and planned mine plant site and waste rock dumps. Project Stage The Mt Todd gold project is a development stage property with proven and probable mineral reserves. 24 Feasibility Study Results The Mt Todd FS evaluates a 50,000 tpd project (“50,000 tpd Project”) that optimizes payable gold, capital efficiency, operating costs and net present value (“NPV”). The 50,000 tpd Project highlights include: • • • • • • • estimated proven and probable mineral reserves of 6.98 million ounces of gold (280 Mt at 0.77 g Au/t) at a cut-off grade of 0.35 g Au/t(1)(2); average annual production of 395,000 ounces of gold over the 16-year mine life, including average annual production of 479,000 ounces of gold per year during the first seven years of operations following commissioning and ramp-up; life of mine average cash costs of $817 per ounce, including average cash costs of $752 per ounce during the first seven years of operations following commissioning and ramp-up; a 16-year operating life; initial capital requirements of $892 million which assume an owner-operated mining fleet, power generated on-site by a third-party, and a locally based employee workforce; after-tax NPV5% of $999.5 million and internal rate of return (“IRR”) of 20.6% at a gold price of $1,600 per ounce and an AUD:USD exchange rate of 0.71; and after-tax NPV5% of $1.7 billion and IRR of 29.4% at a price of $1,900 per ounce of gold and an AUD:USD exchange rate of 0.71 based on the Gold Price and Foreign Exchange Sensitivity Table below. (1) Note to investors: Proven and probable mineral reserves are estimated in accordance with S-K 1300 and CIM Definition Standards. (2) See “Item 1.

Asset sale and salvage value assumptions include end of life re-sale values for mining and processing equipment; and recycle value for steel and pipe from the process plant and other facilities. (1) Net of asset sales. The Mt Todd FS contemplates an owner-operated mining fleet at initial capital of $86 million and sustaining capital of $565 million, inclusive of contingency. The study assumes the equipment will be sold when retired from operations, at an estimated salvage value of $21 million. Fleet operators, along with other employees, are expected to be community based, providing benefits by lower camp-related capital and operating costs. Mining equipment would be maintained through a full maintenance and repair contract with the manufacturer’s authorized dealer. Overall, this approach is expected to produce lower operating costs compared to contract mining. The Mt Todd FS utilizes the efficiency of ore sorting across a broad range of head grades, the natural concentration of gold in the screen undersize material prior to sorting, the efficiency of fine grinding and the resulting improved gold recoveries at a final grind size of P80 40 µm, and the selection of FLSmidth’s VXP mill (“VXP Mills”) as the preferred fine grinding mill. The 50,000 tpd Project incorporates purchasing electrical power from a third-party. The power plant will be owned, operated, and provide power to the Project on a dedicated contract.

Management’s Discussion and Analysis of Financial Condition and Results of Operations – Non-U.S. GAAP Financial Measures for additional disclosure. 27 In November 2020, we modified our agreement with the Jawoyn Association. The modified agreement provides the Jawoyn Association with a gross proceeds royalty (“GPR”) ranging between 0.125% and 2.0%, depending on prevailing gold prices and foreign exchange rates, instead of its previous right to become a 10% participating joint venture partner in Mt Todd (“Jawoyn Royalty”). The modified agreement did not affect the previously agreed 1.0% GPR. The combined GPR range is now from 1.125% to 3.0% and is reflected in the table above. The life of mine production schedule contemplates 280.4 million tonnes of ore containing an estimated 6.98 million ounces of gold at an average grade of 0.77 g Au/t to be processed over a 16-year operating life of the Project. Total recovered gold is expected to be 6.31 million ounces. Average annual gold production over the life of the Project is expected to be 395,000 ounces, which includes averaging 479,000 ounces during the first seven years of commercial operations. Commercial operations are anticipated to begin after two years of construction and a six-month commissioning and ramp- up period. The following table summarizes the production schedule. The shaded portion of the table highlights the impact of sorting which reduces the tonnage processed by 10%, increases the processed grade by a similar percentage, and results in cost savings in the grinding, leaching and tailings handling.

Rex Bryan of Tetra Tech, Inc. is the QP responsible for the Statement of Mineral Resources for the Batman, Heap Leach Pad and Quigleys deposits. Thomas Dyer of RESPEC is the QP responsible for developing the resource WhittleTM pit shell for the Batman Deposit. The effective date of the Batman Deposit, Heap Leach Pad, and Quigleys Deposit mineral resources estimates under the requirements of SK-1300 is December 31, 2022. There have been no changes in the mineral resource estimates since December 31, 2021 because upon review the Company and the relevant qualified persons determined that the same material assumptions and estimates, including all economic parameters for resource estimation purposes, continued to apply as of December 31, 2022. The effective date of the Batman Deposit, Heap Leach Pad, and Quigleys Deposit mineral resource estimates under the requirements of NI 43-101 is December 31, 2021. • Mineral resources that are not mineral reserves have no demonstrated economic viability and do not meet all relevant modifying factors. There was no change in resource estimates as of December 31, 2022 compared to December 31, 2021 as the same material assumptions and criteria were determined to continue to apply to the resource estimates and there was no conversion of resources into reserves in the fiscal year ending December 31, 2022. The mine plan in the Mt Todd FS includes both proven and probable mineral reserves and results in estimated total recovered gold of 6.31 million ounces. 29 The table below presents the estimated mineral reserves for the Project.

Dyer, P.E., is the QP responsible for reporting the Batman Deposit Proven and Probable reserves. Batman deposit reserves are reported using a 0.35 g Au/t cutoff grade. Because all the heap-leach pad reserves are to be fed through the mill, these reserves are reported without a cutoff grade applied. The reserves point of reference is the point where material is fed into the mill. The effective date of the mineral reserve estimates under the requirements of S-K 1300 is December 31, 2022. There have been no changes in the mineral reserve estimates since December 31, 2021 because the Company and the relevant qualified persons determined that the same material assumptions and criteria continued to apply as of December 31, 2022, including that the Company used a cutoff grade higher than the economic cutoff grade such that any intervening changes in the underlying economic assumptions were not material and did not require use of a cutoff grade greater than 0.35 g Au/t for mineral reserve estimation purposes. The effective date of the mineral reserve estimates under the requirements of NI 43-101 is December 31, 2021. • • • Cautionary note to investors: Proven and probable mineral reserves are estimated in accordance with S-K 1300 and CIM Definition Standards. A number of risk factors may adversely affect estimated mineral reserves and mineral resources, any of which may result in a reduction or elimination of reported mineral reserves and mineral resources. See “Item 1A. Risk Factors.” There was no change in reserve estimates as of December 31, 2022 compared to December 31, 2021 as the same material assumptions and criteria were determined to continue to apply to the reserve estimates and there was no depletion of reserves in the fiscal year ending December 31, 2022 as the Mt. Todd Gold Project is in the development stage The tables below show the resource classification criteria and variogram parameters for the Batman resource model. 30 Property Holdings In 2006, through an agreement with Pegasus Gold Australia Pty. Ltd. (“Pegasus”), the NT Government, and the Jawoyn Association, we acquired the concession rights and access to Mt Todd. Also in 2006, through an agreement with the NT Government, we established the rights and obligations of Vista and the NT Government with respect to Mt Todd site care and maintenance and potential future development. In 2017, the latter agreement was extended through the end of 2023 and the Company has requested an additional extension. Total land holdings controlled by Vista Gold Australia are approximately 1,705 Km2. A map showing the location of the mineral licenses (“MLs”) and exploration licenses (“ELs”) and a table with a list of MLs and ELs and the holding requirements are set out below. All of the estimated mineral reserves and resources are located within the boundaries of the MLs and substantially all of the estimated mineral reserves and resources at Mt Todd are located in the Batman deposit. The Batman and Quigleys deposits are located within the MLs. Should a deposit be discovered on the ELs, the portion of the related EL would have to be converted to an ML before mining operations could start. 31 Mineral Licenses MLN 1070 MLN 1071 MLN 1127 MLN 31525 Subtotal Exploration Licenses EL29882 EL29886 EL30898 EL32004 Mt Todd Land Holdings of Vista Gold Australia Estimated Holding Requirements Annual Rent & Annual Work Annual Surface Area (Km2) Location Description (UTM) Mining License Block Location Date/ Grant Date Renewal Date 39.8 March 5, 1993 March 4, 2043 13.3 centered at March 5, 1993 March 4, 2043 approximately 188555E, 435665N March 5, 1993 March 4, 2043 September 3, 2042 September 4, 2017 0.8 1.6 55.4 Admin Fees (thousands of A$) 88 (due March 4) 29 (due March 4) 2 (due March 4) 4 (due September 3) 123 Requirement Expenditure/ Technical Reports Due (thousands of A$) N/A N/A N/A N/A - May 4 May 4 May 4 May 4 Estimated Holding Requirements Location Date/ Grant Date Renewal Date Annual Rent & Annual Work Annual Admin Fees (thousands of A$) Requirement Expenditure/ Technical Reports Due (thousands of A$) September 16, 2013 September 15, 2023 39 (due September 15) 125 May 14 September 16, 2013 September 15, 2023 45 (due September 15) 77 May 14 May 3, 2016 May 2, 2024 13 (due May 2) 12 May 14 November 21, 2019 November 20, 2025 4 (due November 20) 30 May 14 Surface Area (Km2) Location Description 556 595 187 163 (UTM) Centered at approximately 189100E, 84520000N Centered at approximately 200300E, 8452000N Centered at approximately 176100E, 8428700N Centered at approximately 164000E, 8430550N Centered at approximately 160180E, 8445150N ELA32005 Subtotal 149 1,650 Totals A$ Totals US$ (exchange rate of A$1.00 = $0.682 on December 31, 2022) Under application Under application Under application Under application 244 Under application 244 166 101 224 153 The surface land in the area of the contiguous MLs and ELs (excluding EL 32004) is freehold land owned by the Jawoyn Association. Because the Jawoyn Association have title to the land, such land is not part of the lands classified by the government as indigenous lands, and as a result such lands are not subject to an Indigenous land use agreement. Vista has a private agreement with the Jawoyn Association for access to the land. Annually, we are required to submit a care and maintenance MMP to the DITT that details work to be done on the property. We have received approval for all work done on the Project to date and obtained approval for the EIS. We received our operational MMP in June 2021, which is the operating permit that sets out how mine operating strategy will be implemented throughout the mine life in compliance with the EIS and EPBC requirements. The MMP is in the process of being amended to align with the design changes in the Mt Todd FS. The remaining permitting processes are relatively straight-forward and are not expected to impede, to a material extent, our exploration and future development plans. Any future mining will require sufficient surety bonding to fund mine closure. 32 Infrastructure Because Mt Todd was an operating mine, infrastructure exists that reduces initial capital expenditure and significantly reduces capital risk related to infrastructure construction, which has been a major source of capital cost overruns in the mining industry over the last decade. Existing mining infrastructure items include: • • • • • a tailings storage facility with capacity for approximately 80 million tonnes of additional material; a fresh water storage reservoir that would receive a two-meter dam raise and would harvest stormwater expected to be sufficient to provide process water for year-round operations for a 50,000 tpd operation; a natural gas pipeline at site that can supply sufficient natural gas to meet the Project’s energy requirements which, coupled with the planned power generating plant, would save considerably on Project operating costs compared to grid-supplied power; a paved road to site; and current electrical connection to the NT electric grid. In addition, we expect reduced earthworks costs due to the process plant location being the same as the previous process plant, which has already been cleared and graded. Other benefits of Mt Todd’s NT location include: • • • the Stuart highway – the main North / South highway in the NT is less than 10 kilometers from the Project site; rail line parallel to the Stuart highway; and the regional center of Katherine (population approximately 12,000) less than 40 kilometers from site and the NT capital of Darwin less than 290 kilometers from the Project site, which has port access. The area has both historical and current mining activity and therefore a portion of the skilled workforce should be able to be sourced locally. In addition, Katherine offers the necessary support functions that are typically found in a medium-sized city with regard to supplies, accommodations, communications, etc. Planned infrastructure for the site includes the following: • ammonium nitrate and fuel oil facility; • mine support facilities (heavy vehicle workshop, lube farm, washdown and tire change, warehouse, fuel farm, mining offices, core storage facility); heap leach facility; small accommodation camp for occasional contractor use; • • • water treatment plant; • • power supply; pit dewatering; • mine services; • • • communications; gatehouse; and expanded existing and additional tailings storage facility. Geological Setting, Mineralization, and Deposit Type Mt Todd is situated within the southeastern portion of the Early Proterozoic Pine Creek Geosyncline. Meta-sediments, granitites, basic intrusives, acidic and intermediate volcanic rocks occur within this geological province. Within the Mt Todd region, the oldest outcropping rocks are assigned to the Burrell Creek Formation. These rocks consist primarily of interbedded greywackes, siltstones, and shales of turbidite affinity, which are interspersed with minor volcanics. The 33 Burrell Creek Formation is overlain by interbedded greywackes, mudstones, tuffs, minor conglomerates, mafic to intermediate volcanics and banded ironstone of the Tollis Formation. The Burrell Creek Formation and Tollis Formation comprise the Finniss River Group. The Finniss River Group strata have been folded about northerly trending F1 fold axes. The folds are closed to open style and have moderate westerly dipping axial planes with some sections being overturned. A later north-south compression event resulted in east-west trending open style upright D2 folds. The Finniss River Group has been regionally metamorphosed to lower green schist facies. Late and Post Orogenic granite intrusions of the Cullen Batholith occurred from 1,789 Ma to 1,730 Ma and brought about local contact metamorphism to hornblende hornfels facies. The Batman pit geology consists of a sequence of hornfelsed interbedded greywackes and shales with minor thin beds of felsic tuff. Bedding consistently strikes at 325 degrees, dipping 40 degrees to 60 degrees to the southwest. Northerly trending sheeted quartz sulfide veins and joints striking at 0 degrees to 20 degrees and dipping 60 degrees to the east are the major controls for mineralization in the Batman pit. The veins are 1 to 100 millimeters in thickness with an average thickness of around 8 to 10 millimeters and occur in sheets with up to 20 veins per horizontal meter. These sheeted veins are the main source of gold mineralization in the Batman pit. In general, the Batman pit extends 1,600 meters in length by 1,100 meters in width and has been drill tested to a depth of 800 meters down-dip. The deposit is open along strike and at depth. The mineralization within the Batman pit is directly related to the intensity of the north-south trending quartz sulfide veining. The lithological units impact the orientation and intensity of mineralization. Sulfide minerals associated with the gold mineralization are pyrite, pyrrhotite and lesser amounts of chalcopyrite, bismuthinite and arsenopyrite. Galena and sphalerite are also present, but appear to be post-gold mineralization, and are related to calcite veining in the bedding plains and the east-west trending faults and joints. Two main styles of mineralization have been identified in the Batman pit. These are the north-south trending vein mineralization and bedding parallel mineralization. Gold mineralization in the Batman deposit occurs in sheeted veins within silicified greywackes/shales/siltstones. The Batman deposit strikes north-northeast and dips steeply to the east. Higher grade zones of the deposit plunge to the south. The core zone is approximately 200-250 meters wide and 1.5 kilometers long, with several hanging wall structures providing additional width to the orebody. Mineralization is open at depth as well as along strike, although the intensity of mineralization weakens to the north and south along strike. Historical Operations The Batman gold prospect is located in the Pine Creek Geosyncline that was worked from early in the 20th century. Gold and tin were discovered in the Mt Todd area in 1889. Most deposits were worked in the period from 1902 to 1914. A total of 7.80 tonnes of tin concentrate was obtained from cassiterite-bearing quartz-kaolin lodes at the Morris and Shamrock mines. The Jones Brothers reef was the most extensively mined gold-bearing quartz vein, with a recorded production of 28.45 kg Au. This reef consists of a steeply dipping ferruginous quartz lode within tightly folded greywackes. The Yinberrie Wolfram field, discovered in 1913, is located 5 kilometers west of Mt Todd. Tungsten, molybdenum and bismuth mineralization was discovered in greisenized aplite dykes and quartz veins in a small stock of the Cullen Batholith. Recorded production from numerous shallow shafts is 163 tonnes of tungsten, 130 kg of molybdenite and a small quantity of bismuth. Exploration for uranium began in the 1950s. Small uranium prospects were discovered in sheared or greisenized portions of the Cullen Batholith in the vicinity of the Edith River. Australian Ores and Minerals Limited (“AOM”) in a joint venture with Wandaroo Mining Corporation and Esso Standard Oil took out a number of mining leases in the Mt Todd area during 1975. Initial exploration consisted of stream sediment sampling, rock chip sampling, and geological reconnaissance for a variety of commodities. A number of geochemical anomalies were found primarily in the vicinity of old workings. Follow-up work concentrated on alluvial tin and, later, auriferous reefs. Backhoe trenching, costeaning, and ground follow-up were the favored mode of exploration. Two diamond drillholes were drilled at Quigleys. Despite determining that the gold potential of the reefs in the area was promising, AOM ceased work around Mt Todd. 34 The Arafura Mining Corporation, CRA Exploration, and Marriaz Pty Ltd all explored the Mt Todd area at different times between 1975 and 1983. In late 1981, CRA Exploration conducted grid surveys, geological mapping and a 14 diamond drillhole program, with an aggregate meterage of 676.5 meters, to test the gold content of Quigleys Reef over a strike length of 800 meters. Following this program CRA Exploration did not proceed with further exploration. During late 1986, Pacific Gold Mines NL (“Pacific”) undertook exploration in the area which resulted in small-scale open cut mining on the Quigleys and Golf reefs, and limited test mining at the Alpha, Bravo, Charlie and Delta pits. Ore was transported to a carbon in pulp (“CIP”) plant owned by Pacific at Moline. This continued until December 1987. Pacific ceased operations in the area in February 1988 having produced approximately 86,000 tonnes grading 4 g Au/t (historical reported production, not S-K 1300 or NI 43-101 compliant). Subsequent negotiations between the joint venture partners Shell Company of Australia (“Billiton”), Zapopan NL (“Zapopan”) and Pacific resulted in the acquisition of this ground and incorporation into the joint venture. Billiton, who was the managing partner in an exploration program in the joint venture with Zapopan, discovered the Mt Todd mineralization, or more specifically the Batman deposit, in May 1988. In 1992, Pegasus acquired a shareholding in Zapopan, following which Zapopan acquired Billiton’s interest. Pegasus progressively increased their shareholding until they acquired full ownership of Zapopan in July 1995. Historical preliminary studies (not S-K 1300 or NI 43-101 compliant) for Phase I, a heap leach operation which focused predominately on the oxide portion of the deposit, commenced during 1992 culminating in an engineering, procurement, construction management (“EPCM”) award to Minproc in November of that year. The Phase I project was predicated upon a 4 million tonne per year (“Mtpy”) heap leach plant, which came on stream in late 1993. The treatment rate was subsequently expanded to a rate of 6 Mtpy in late 1994. Based on our review of the historical project files, we believe that approximately 21.4 million tonnes grading 1.05 grams gold per tonne and containing 723,795 ounces of gold were extracted between 1993 and the termination of mining in 2000. Processing was by a combination of heap leach production from oxide ore and cyanidation of sulfide ore. The remaining mineralization consists of sulfide mineralization lying below and along strike of the existing open pit, and in hanging wall structures parallel to the main zone in the existing open pit. Historical heap leach production is shown in the table below: Category Historical Heap Leach Production Reported Tonnes Leached (million) Head Grade (g Au/t) Recovery (%) 13.2 0.96 53.8 Gold Recovered (oz) 220,755 Cost/t (AUD) Cost/oz (AUD) 8.33 500 NOTE: All tonnages and grades are historical production numbers that pre-date Vista’s ownership. The QPs and issuer consider historical estimates to be relevant but not current. Phase II involved expanding to 8 Mtpy and treatment through a flotation and carbon-in-leach circuit. The feasibility study was conducted by a joint venture between Bateman Kinhill and Kilborne (“BKK”) and was completed in June 1995. 35 The Pegasus board approved the project on August 17, 1995 and awarded an EPCM contract to BKK in October 1995. Commissioning commenced in November 1996. Final capital costs to complete the project were AUD232 million (USD181 million). Design capacity was never achieved due to inadequacies in the third and fourth stages of the crushing circuit. A throughput rate of just under 7 Mtpy was achieved by mid-1997; however, problems with the flotation circuit which resulted in reduced recoveries necessitated closure of this circuit. Subsequently, high reagent consumption, as a result of cyanide soluble copper minerals, further hindered efforts to reach design production. Operating costs were above those predicted in the feasibility study. The spot price of gold deteriorated from above USD400 in early 1996 to below USD300 per ounce at the end of 1997. This, combined with underperformance of the project and higher operating costs led to the mine being closed and placed on care and maintenance on November 14, 1997. In February 1999, General Gold Resources Pty. Ltd. (“General Gold”) agreed to form a joint venture with Multiplex Resources Pty Ltd (“Multiplex”) and Pegasus to own, operate, and explore the mine. Initial equity participation in the joint venture was General Gold 2%, Multiplex 93%, and Pegasus 5%. The joint venture appointed General Gold as mine operator, which contributed the operating plan in exchange for a 50% share of the net cash flow generated by the project, after allowing for acquisition costs and environmental sinking fund contributions. General Gold operated the mine from March 1999 to July 2000. Operations ceased in July 2000, and Pegasus, through the Deed Administrators, regained possession of various parts of the mine assets in order to recoup the balance of purchase price owed to it. Most of the equipment was sold in June 2001 and removed from the mine. In March 2006, Vista acquired the concession rights from the Deed Administrators and surface rights from the Jawoyn Association and entered into a contract with the NT Government. Exploration Licenses Since acquiring the Mt Todd ELs, Vista has conducted an ongoing exploration program that includes prospecting, geologic mapping, rock and soil sampling, geophysical surveys and exploration drilling. Equipment and personnel were mobilized from the site or from an exploration base camp established in the central part of the ELs. The work was conducted by geologists and field technicians. The exploration effort initially focused on follow-up work on targets developed by Pegasus during their tenure on the property. These included the RKD target, Tablelands, and Silver Spray. During a review of Pegasus’ airborne geophysical survey data, five distinct magnetic highs were observed located within sedimentary rocks that should have a low magnetic signature. These features are similar to those at Batman, which, as a result of the included pyrrhotite, exhibits a strong magnetic high. The geophysical targets were prioritized following review of historical work in the area and site visits. To date, two of the geophysical targets, Golden Eye and Snowdrop, have been drilled and a third, Black Hill, has been covered by soil sampling. The Wandie target has a different magnetic signature. Field examination identified small-scale pits on an iron-rich outcropping. There are no reportable mineral resources and mineral reserves on the ELs. No data from the ELs were used in the development of the Mt Todd FS results.

The targets are distinct magnetic highs located within sedimentary rocks that should have a low magnetic signature. These features are similar to those at Batman, which, as a result of the included pyrrhotite, exhibits a strong magnetic high. Mineralization at the Quigleys deposit is interpreted to occur within a series of mineralized shears that strike north northwest and dip 30 to 35 degrees to the west. The main shear extends for nearly one kilometer along the strike and has been drilled to a vertical depth of 230 meters. The mineral resource estimate has been defined by 632 drill holes drilled by Pegasus and Billiton Australia Gold Pty. Ltd. in the late 1980s through the mid-1990s. Tetra Tech reviewed the integrity of the drill-hole database and developed a computer model to estimate and classify the estimated mineral resources. The model reflected Tetra Tech’s geological interpretation of the deposit, which constrained the mineralization to the shear zones using geological information and assays from 49,178 samples obtained from the drilling. Lower grade, erratic mineralization in the hanging wall of the shears has not been included in the mineral resource estimate. Sampling and assaying were performed under the supervision of prior operators in conjunction with evaluation of the Batman pit and are discussed in the Mt Todd FS, as part of the overall Project sampling and assaying methodology. Drilling Batman Deposit The Batman deposit resource drillhole database consists of both pre-Vista and Vista drill holes. All of the Vista resource drill holes are HQ-size core holes. Vista has drilled a total of 92 HQ diamond drill holes totaling 58,863 meters. All of the Vista diamond drill core samples were sawn into half splits for assaying purposes. The pre-2007 exploration database (pre-Vista) consists of 743 drill holes, of which 226 are diamond drill holes and 517 are percussion drill holes. These drill holes total approximately 98,000 meters. The diamond core was a combination of NQ and HQ sizes, with the NQ core being sawed into half splits and the HQ core being sawed into quarter splits. The table below shows a summary of Batman Deposit drilling from 1988 to 2017. A large percentage of the historical drilling was by reverse circulation (“RC”) of less than 100 meters in depth. The RC drilling was used for ore grade control during the mining operations of Pegasus and General Gold Resources. Vista’s drilling discovered a larger Batman Deposit resource by probing deeper with diamond drilling averaging 550 meters in depth. 37 Batman Deposit Drilling History Date 1988 1989 1990 1991 1992 1993 Reference Truelove Kenny, Wegmann, Fuccenecco Wegmann, Fuccenecco, Gibbs Billiton Zapopan Zapopan 1994-1997 Pegasus Gold 1998-2000 General Gold Resources 2007 2008 2010 2011 2012 2015 Vista Vista Vista Vista Vista Vista 2016-2017 Vista 1988-2017 Batman Total Vista Drilling 2012 – 2017 Holes (#) Percussion (m) Diamond (m) 17 133 122 149 18 16 170 105 25 16 12 7 27 5 4 1,475 6,263 — 501 — — — — — — — — — — — — 8,562 5,060 202 1,375 — — 7,436 9,883 8,938 6,864 4,480 17,439 3,185 1,635 RC (m) — 3,065 8,072 3,090 1,320 2,814 22,534 26,365 — — — — — — — 826 8,239 75,059 67,260 Between the fourth quarter of 2012 and the end of the first quarter of 2017, the Vista exploration program at the Batman Deposit consisted of 22 diamond core drillholes containing 12,530 meters that targeted both infill definitional drilling and step-out drilling. The majority of drilling was angled so as to be approximately perpendicular to the mineralized core. This orientation more accurately transects the true thickness of the mineralization. The Batman Deposit mineralization forms a set of stacked plates that strike to the north and plunge steeply to the east. These mineralized zones have been defined by wireframes which are used to constrain the higher grades for resource estimation. Early drilling sampled the deposit near the surface allowing for shorter drillhole depths. Exploring the deeper portions of the deposit has required drill collars to be offset to the east with longer drillhole lengths to reach the mineralized zone. Recent Vista drilling in particular has targeted the deeper portions of the Batman Deposit. The positioning of the Vista drillhole collars was constrained to be outside of the flooded historical pit. Most Vista drilling has been oriented so as to transect the higher-grade mineralized zone. While there are random high-grade intercepts outside of the core, the majority of higher-grade mineralization resides in the core zone of the deposit. Quigleys The table below shows the Quigleys Deposit drilling history. The Quigleys Deposit was mined from 1982 to 1987 during which the largest amount of drilling was percussion type used for ore grade control. Relevant intervals of mineralization are contained within blanket-like zones which are modeled with 3-D wireframes for resource estimation. The mineralized zones have been defined by wireframes which are used to constrain the higher grades for the resource estimation. The majority of drilling was angled so as to be approximately perpendicular to the mineralized 38 core. This orientation more accurately transects the true thickness of the mineralization. While there are random high- grade intercepts outside of the core, the majority of higher-grade mineralization resides within the defined zones. In 2011, Vista explored the potential for a deeper deposit with three diamond drillholes, each over 350 meters in depth.

Vista’s drilling discovered a larger Batman resource by probing deeper with diamond drilling averaging 550 meters in depth. While there are random high-grade intercepts outside of the core, the majority of higher-grade mineralization at Batman resides in the core zone of the deposit. Relevant intervals of mineralization at Quigleys Deposit are contained within blanket-like zones which are modeled with 3-D wireframes for resource estimation. While there are random high-grade intercepts outside of the core zone, the majority of higher-grade mineralization at the Quigleys Deposit resides within the defined zones. 2020-2022 Drilling Program Results and Exploration Targets Between late 2020 and early 2022, we completed an exploration drilling program designed to demonstrate that the Batman, Golf Tollis, and Quigleys deposits are not independent of each other but connected by structure and mineralization. This program consisted of 26 drill holes totaling 8,887 meters of HQ diamond core. The program consistently intersected mineralization predicted by our geologic model and demonstrated both horizontal and vertical continuity of the targeted structures. Additionally, the program identified four quality exploration targets as well as other potential structures along a 5.4-km portion of the 24-km Batman-Driffield Trend that contains the Batman, Golf Tollis, and Quigleys deposits. Sampling, Analysis and Data Verification The same sampling method and approach has been used for all diamond drillholes completed by Vista at Mt Todd. The drill core, upon removal from the core barrel, was placed into plastic core boxes. The plastic core boxes were transported to the sample preparation building where the core was marked, geologically logged, geotechnically logged, photographed, and cut into halves. One-half was placed into sample bags as nominal one-meter sample lengths, and the other half retained for future reference. The only exception to this was when a portion of the remaining core had been flagged for use in the ongoing metallurgical test work. The bagged samples had sample tags placed both inside and on the outside of the sample bags. The individual samples were grouped into “lots” for submission to Northern Analytical Laboratories for sample preparation and analytical testing. All of this work was done under the supervision of a Vista geologist. The following section describes the sample preparation, analyses and security undertaken by Vista through the Mt Todd FS resource update. 39 The diamond drilling program was conducted under the supervision of the geologic staff composed of a chief geologist, several experienced geologists, and a core handling/cutting crew. The core handling crew was recruited locally. Facilities for the core processing included an enclosed core logging shed and a covered cutting and storage area that was fenced in. Both of these facilities were considered to be limited access areas and kept secured when work was not in progress. The diamond drill core was boxed and stacked at the rig by the drill crews. Core was then picked up daily by members of the core handling crew and transported directly to the core logging shed. Processing of the core included photographing, geotechnical and geologic logging, and marking the core for sampling. The nominal sample interval was one meter. When this process was completed, the core was moved into the core cutting/storage area where it was laid out for cutting and sampling. The core was logged using the following procedures: • • • • • one-meter depth intervals were marked out on the core by a member of the geologic staff; core orientation (bottom of core) was marked with a solid line when at least three orientation marks aligned and were used for structural measurements. When orientation marks were insufficient an estimated orientation was indicated by a dashed line; geologic logging was then done by a member of the geologic staff. Assay intervals were selected at that time and a cut line marked on the core. The standard sample interval was one meter, with a minimum of 0.4 meters and a maximum of 1.4 meters; blind sample numbers were then assigned based on pre-labeled sample bags. Sample intervals were then indicated in the core tray at the appropriate locations; and each core tray was photographed and restacked on pallets pending sample cutting and stored on site indefinitely. The core was then cut using diamond saws with each interval placed in sample bags. At this time, the standards and blanks were also placed in plastic bags for inclusion in the shipment. A reference standard or a blank was inserted at a minimum ratio of 1 in 10 and at suspected high-grade intervals additional blanks sample were added. Standard reference material was sourced from Ore Research & Exploration Pty Ltd and provided in 60 g sealed packets. When a sequence of five samples was completed, they were placed in a shipping bag and closed with a zip tie. All of these samples were kept in the secure area until crated for shipping. Samples were placed in crates for shipping with 100 samples per crate (20 shipping bags) and sealed. The sealed crates were stacked outside the core logging shed until picked up for transport. The following laboratories have been used for sample preparation, analyses, and check assays: Laboratory ALS | Minerals Address Purpose Abbreviation Certifications 31 Denninup Way Malaga, WA 6090 Main assay analyses ALS ALS | Minerals 13 Price St Alice Springs, NT 0870 Sample Preparation ALS Alice Springs ISO:9001:2008 and ISO 17025 Certified ISO 9001:2008 and ISO 17025 Certified Genalysis Laboratory Services (Intertek Group) 15 Davison St Maddington, WA 6109 Check Analyses Genalysis Unable to verify North Australian Laboratories Pty Ltd (“NAL”) NT Environmental Laboratories (Intertek Group) MLN 792 Eleanor Rd Pine Creek, NT 0847 Alternative assay analyses NAL ISO 17025 Certified 3407 Export Dr Berrimah, NT 0828 Check Analyses NTEL ISO 17025 40 Vista is completely independent of each of the above listed analytical testing entities, other than the engagement of said entities as a service provider. Each of the laboratories listed follow their own quality controls based on international standards. For example, ALS uses accredited methods specified by ISO/IEC 17025 in North America and Australia. The standards specify a recipe and set of quality control steps that the laboratory should follow including how the sample should be coded to obscure its relationship to the drilling geometry; how the received sample should be prepared; what analytical steps need be taken, given the required detection level and material analyzed, what instruments should be employed, what internal quality controls should be done such as: periodic assaying of duplicate samples, the insertion of certified calibration samples; utilizing blanks; and including a required number of randomized samples. Mt Todd as a gold project requires assays to be done with the industry standard of fire assay. To get these fire assay results core samples from drillholes are split at Mt Todd into two with one archived and the other sent to an analytical laboratory. At the lab the sample is pulverized into a powder, with a subsample taken for fire assay. This subsample is then mixed with a fluxing agent. The remaining pulverized material is called a pulp archive, which can be used for within and between laboratory validations. The chosen sample is then heated in a furnace where it fuses and separates into a “button” which contains the gold. There are several methods to extract the gold from the button. The most common method is by combining the button with lead as a collector. The lead oxidizes and is absorbed into a cupel leaving a gold bead. Due to the relatively low concentration of gold at Mt Todd the lab must choose an analytical method able to detect at least 5ppb gold. The methods are generally by atomic absorption or inductively coupled plasma-mass spectrometry. The bead is dissolved in aqua regia or dissolved in hydrochloric acid and then analyzed by the selected instrument. The resultant assay values are reported by an assay certificate which is electronically or physically sent to the staff at Mt Todd. The assay results are entered with the drilling database. Vista requires periodic rechecking of assays both within and between laboratories. As an example, prior to the 2011 drilling campaign, the majority of samples were transported first to ALS in Alice Springs, NT for sample preparation. After preparation, samples were then forwarded on to ALS in Malaga, WA for assay analyses. One in every 20 pulp or reject was sent from ALS in Alice Springs to NAL, Vista was notified by email which samples were sent to NAL. For the 2011- 2012 drilling campaign samples for assay were sent to NAL lab in Pine Creek, NT. Following completion of assay results, all pulps and reject material was shipped back to the Mt Todd site and stored. A comprehensive check of the quality of 12,365 assays in the database was undertaken by an outside auditor. Records were selected from among those that relate to mineralization that is still in situ. These were divided into three subsets, to be checked by three individual checkers. An additional 1,812 records were spot-checked in greater detail by a fourth individual. After the checking was done, from the original 12,365 records, 95% were selected that had gold value in the database and a gold assay in a source document such as an assay certificate. Of the assay pairs, 8,549 were “historical” in the sense of dating prior to Vista’s acquisition of the project and 3,262 assay pairs originate with Vista’s work. For context, Mt Todd assay table as of August of 2011 contained 118,550 records, 26,579 of them originating from Vista’s work. Eight significant outliers were found with gold values in the database that differed from the source documents. Those eight were double-checked and were found to be real cases of the database containing data that differ from the source documents. The below table shows that most of the differences between the gold values in the database and those gleaned from the source documents are very small, although around economic cutoff grades the differences may well represent large percentages. More than 99% of the differences fall in the range -0.1 ppm Au to +0.1 ppm Au which is below the 0.4 ppm cutoff grade. However, a Mann-Whitney Test suggests that the differences between the two populations are not statistically different. Prior to the 2011 drilling campaign, the majority of samples were transported first to ALS in Alice Springs, NT for sample preparation. After preparation, samples were then forwarded on to ALS in Malaga, Western Australia for assay analyses. One in every 20 pulp or reject was sent from ALS in Alice Springs to NAL, Vista was notified by email which samples were sent to NAL. For the 2011-2012 drilling campaign samples for assay were sent to NAL lab in Pine Creek, NT. Check assays on one in every 20 pulps or rejects were completed by NT Environmental Laboratories. Following completion of assay results, all pulps and reject material were shipped back to the Project site and stored. 41 Comparison of Assay Values between the Database and Source Documents Center of Cell Range in ppm Au Frequency Percent Cumulative (+/- 0.1 ppm Au) -1.2 -1 -0.8 -0.6 -0.4 -0.2 0 0.2 0.4 0.6 0.8 1 1.2 0 0 1 0 0 3 0.00 0.00 0.01 0.00 0.00 0.04 8,539 99.88 5 0 0 0 0 1 0.06 0.00 0.00 0.00 0.00 0.01 Percent 0.00 0.00 0.01 0.01 0.01 0.05 99.93 0.99 99.99 99.99 99.99 99.99 100.00 Differences with no rounding or truncation of data The tables show the comparison of the gold grade assays within the database and source documents. One of the three data sets checked contained 3,262 assays from drilling campaigns by Vista in 2007 and 2008. Checks of the Vista data against original sources were done by one individual, using essentially the same procedures as had been used for checking the historical assays. A summary table of the findings is presented below. Of the 12 differences noted, two are significant. A gold value of 0.005 ppm Au in the database compared to the correct gold value of 0.8 ppm Au. A gold value of 1.08 ppm Au in the database compared to the correct gold value of 0.01 ppm Au. In addition, a separate detailed audit was done on 638 assays on Vista drillhole VB08-036. This audit shows that discrepancies within the database on the global resource estimate are not material.

As an example, prior to the 2011 drilling campaign, the majority of samples were transported first to ALS in Alice Springs, NT for sample preparation. After preparation, samples were then forwarded on to ALS in Malaga, WA for assay analyses. One in every 20 pulps or rejects was sent from ALS in Alice Springs to NAL, Vista was notified by email which samples were sent to NAL. For the 2011-2012 drilling campaign samples for assay were sent to NAL lab in Pine Creek, NT. No bias in assays was found with a slope of 0.992 and a correlation of 99%. There was only one significant difference that was detected from a total of 2,948 comparisons. The Company’s assaying protocols are observed and required for every assay program, regardless of whether the exploration work is for resource estimation or metallurgical testing. John W. Rozelle, Senior Vice President of Vista and a qualified person as defined by S-K 1300 and NI 43-101, has verified the data disclosed in this document, including sampling, analytical and test data underlying the information contained in the disclosure. Sample Security NAL is the primary laboratory we use for analysis of drill core assays. The NAL laboratory is located in the town of Pine Creek, approximately 50 kilometers distant by road from the Project site. Samples were picked up and transported by NAL employees. Sample shipments were scheduled for approximately once a week. The sealed crates were picked up on site by NAL for direct road transport to the assay lab. A sample transmittal form was prepared and included with each shipment and a copy was filed in the geology office on site. When the shipment left site, sample transmittals were prepared and e-mailed to NAL. When the shipment arrived at the preparation facility the samples were lined out and a confirmation of sample receipt was e-mailed back to Vista. Statistical analyses of the various drilling populations and quality assurance/quality control samples have neither identified nor highlighted any reasons to not accept the data as representative of the tenor and grade of the mineralization estimated at the Batman deposit. Mining Operations The Project is designed to be a large open-pit mining operation that will utilize large-scale mining equipment in a drill/blast/load/haul operation. Ore is planned to be processed in a comminution circuit consisting of large-scale equipment, including: a gyratory crusher, cone crushers, high pressure grinding roll (“HPGR”) crushers followed by X-ray 43 transmission (“XRT”) and laser sorting, and primary ball mills, followed by VXP Mills, as discussed in greater detail below. Vista plans to recover gold in a conventional CIP recovery circuit. Mineral Processing The flowsheet consists of open-circuit primary crushing, closed-circuit secondary crushing, closed-circuit tertiary crushing using HPGR crushers, ore sorting, two-stage grinding, cyclone classification, pre-leach thickening, leach and adsorption, elution electrowinning and smelting, carbon regeneration, tailings detoxification and disposal to conventional tailings storage facility. The flowsheet for the Project is illustrated below. Metallurgical Testing Our metallurgical test work programs have confirmed: (1) ore hardness of the Batman deposit is consistent throughout the deposit and does not change at depth; (2) the selection of HPGR crusher technology as part of the comminution circuit; (3) the selection of ore sorting technology to eliminate low-grade material after crushing and prior to grinding; (4) estimated gold recovery rates based on optimized grind size and leach conditions; and (5) the processing of material from the historical heap leach pad at the end of the proposed mine life. The test work results collated from the 2011 and 2012 testing campaigns and additional metallurgical and process test work conducted in 2016, 2017, 2018, and 2019, together with the process design criteria, were used to develop the process flow sheet and mass balance. 44 Ore Hardness Bond ball mill work indices (“BWi”) were determined at a grind size of P80 of 100 mesh for the various products, namely HPGR crusher, ore-sorting, composite samples and waste material. The test results indicate the following: • The BWi for the ore sorter feed (plus 5/8” screened HPGR crusher product) was higher than the composite samples prepared from the minus 5/8” screened HPGR crusher product. Hence, it is reasonable to conclude that the uncrushed material from the HPGR is harder than the crushed product. • The rejected waste material had a BWi higher than both the composite sample prepared from the minus 5/8” HPGR crusher product and the XRT ore sorting product that is returned to the HPGR crushers. • The BWi for the final HPGR product ranged from 23.10 to 26.63. A BWi of 24.50 was selected for the design of the primary ball mill circuit. The results of this test work support two main conclusions: (1) that the hardness of ore at the Batman deposit is relatively constant; and (2) that ore hardness at the Batman deposit does not change at depth. This test work validates the Company’s prior test work and supports Vista’s revised comminution circuit design, which is designed to crush and grind material with an average BWi of 26.2 kWh/t. HPGR Crusher Selection The proposed 50,000 tpd Project comminution circuit incorporates the use of a gyratory crusher and two cone crushers for the primary and secondary stages, respectively, and the use of two HPGR crushers as the third-stage of the crushing circuit. The test work assessed the difference in power requirements between a primary/SAG/ball mill circuit, a conventional 3- stage crush/ball mill circuit, and a 3-stage HPGR crush/ball mill circuit (with 3rd stage HPGR crushing and 2-stage grinding) to generate a P80 passing 40 μm product. This test work also confirms our prior test work and supports our comminution circuit design. The use of HPGR crushers is anticipated to (a) produce a product that can be ground more efficiently (lower BWi); and (b) reduce energy requirements when compared to a SAG Mill design. Ore Sorting The bulk ore sorting tests comprised four, five-tonne composites; and one, one-tonne composite prepared from 3.75" drill core. In addition to these composites, three one-tonne composites were made from 2.75” drill core. Four of the 3.75” composites contained predominately sulfide mineralization and one composite contained mixed oxide/sulfide material that is encountered on the periphery of the deposit. The remaining three 2.75” drill core composites all contained sulfide material. The drill core was HPGR crushed and screened at 5/8” at the facilities of Thyssen Krupp Industries near Dusseldorf, Germany. The plus 5/8” material was sent to the test facility of Tomra Sorting Solutions near Hamburg, Germany where this material was initially sorted using XRT sorting. A total of 12 sorting tests were completed. The XRT rejects were then subjected to laser sorting to produce a final reject. All material (minus 5/8” HPGR crushed, XRT product, laser product and sorting reject) was sent to the metallurgical laboratory of Resource Development Inc. in Wheat Ridge, Colorado for subsequent sample preparation, assaying and additional metallurgical testing. On a material mass basis, the combined XRT and laser sorting tests confirmed the Company’s expectation that it can reject approximately 10% of the run-of-mine feed as waste (test results range from 6.8% to 11.0%). The average grade of the rejected material is estimated to be 0.12 g Au/t (results range from 0.06 g Au/t to 0.23 g Au/t) compared to the mine cut- off grade of 0.35 g Au/t, resulting in a gold loss from the rejected waste of approximately 1.3%. The improvement in mill feed grade is expected to be approximately 8%, resulting in run-of-mine average mill feed grade of 0.84 g Au/t compared to the life-of-mine Batman Pit mineral reserve grade of 0.79 g Au/t. 45 Gold Recoveries We evaluated gold recoveries using two-stage grinding and a finer product size. This test work has confirmed that the introduction of ore sorting to reduce the leach tonnage by approximately 10% and finer grinding to P80 of 40 µm yields an increase in recovery to ~91.6% on a weighted-average basis, net of solution losses. A total of 71 additional leach tests were completed using the above mentioned two-staged grinding to confirm our resulting leach recoveries of 91.9%, net of solution losses. This test work has also confirmed a cyanide consumption rate of 0.88 kg per tonne. Our recovery plant design utilizing a conventional, industry-proven, CIP circuit remains unchanged. Existing Heap Leach Pad In addition to analysis of freshly-mined material from the Batman deposit, Vista has analyzed the potential to process nearly 13.4 million tonnes of material from the existing heap leach pad at Mt Todd. The historical Mt Todd mine started as a heap leach operation with historical records indicating that the average grade of material placed on the pad was 0.96 g Au/t. Although the material was partially leached in the mid-1990s, Vista has drilled 24 air-rotary holes into the heap leach pad and assayed 361 samples, and Tetra Tech created a 3D resource model that has an average grade of 0.54 g Au/t. Initial evaluation efforts focused on re-starting the heap leach pad. Bottle roll and column tests were completed, both of which supported the leachability of the material with gold recovery rates around 35%. However, poor in situ permeability rates caused Vista to ultimately abandon plans to re-start the heap. A total of 16 tests were completed on composites taken from 11 of the heap leach pad drill holes. The samples were ground to the size of P80 of 40 μm and pre-treated with lime and 100 g/t of lead nitrate to suppress copper leaching. The material was then leached for 24 hours. These results ranged between 71 and 91% with the average being 82.2% for this material when processed through the proposed CIP flowsheet. The Mt Todd FS assumes that the existing heap leach pad will be left in place and processed through the mill at the end of mine life. This ultimately is expected to reduce the scope of reclamation of the heap leach pad to the pad liner and regrading only. Permitting During September 2014, the EIS was approved. In its Assessment Report, the NT EPA advised that it had assessed the environmental impacts of Vista’s development plans for Mt Todd and concluded that it can proceed, subject to a number of recommendations which are outlined in the Assessment Report. The NT EPA Assessment Report includes 28 recommendations which are addressed as part of the MMP. The approval of the EIS resulted in the requirement to obtain an authorization of a controlled activity as required under the EPBC as it relates to the Gouldian Finch. The EPBC authorization was granted by the Australian Commonwealth Department of Environment and Energy in January 2018. In November 2018, we applied for the MMP approval, which is the operating permit that sets out how the mine operating strategy will be implemented throughout the mine life in compliance with the EIS and EPBC requirements. The MMP was approved in June 2021 and is in the process of being amended to align with the larger-scale design in the Mt Todd FS. The changes to the waste rock dump design have been referred to the NT EPA as required under the Environmental Protection Act 2019 for its consideration. 46 Environmental, Social and Community Factors A number of environmental studies have been conducted at Mt Todd in support of the EIS and as required for environmental and operational permits. Studies conducted have investigated soils, climate and meteorology, geology, geochemistry, biological resources, cultural and anthropological sites, socio-economics, hydrogeology, and water quality. The EIS for the Project was submitted in June 2013. The document was prepared by independent consultants, GHD Pty Ltd., to identify potential environmental, social, transport, cultural and economic impacts associated with reopening and operating the mine. NT EPA provided its final assessment of the Project in June 2014. Final approval was given in September 2014. The Jawoyn people have been consulted with and involved in the planning of the Project. Areas of aboriginal significance have been designated, and the mine plan has avoided development in these restricted works areas. Water Treatment We obtained approval of a waste discharge license from the NT Government that authorized the release of treated water from the Mt Todd site during the wet season in accordance with an 80% protection limit environmental standard. We discharged treated water in compliance with the standards. The existing Batman pit has the capacity to contain approximately 11.5 gigaliters of water. At the end of December 2022, the pit contained approximately 0.7 gigaliters of water due to previous dewatering operations. The present volume of water in the pit will not present any major issues when resuming operations in the Batman pit. 2023 Project Development Plans The Company is evaluating a smaller scale project at Mt Todd, targeting a significantly lower initial capital cost while maintaining operating costs very close to those estimated in the Mt Todd FS. A smaller project would be scalable, allowing for throughput expansion or mine-life extension. The completion of this study is expected in the first quarter of 2023. The strategic process with CIBC Capital Markets is ongoing and remains a top priority. Vista reduced its recurring costs in 2022, and reducing costs and maximizing effectiveness continue to be high priorities in 2023. Vista expects to incur expenditures of approximately $2,100 for its Mt Todd site maintenance and environmental stewardship activities. ITEM 3. LEGAL PROCEEDINGS. We are not aware of a) any material pending litigation or of any proceedings known to be contemplated by governmental authorities that are, or would be, likely to have a material adverse effect upon us or our operations, taken as a whole and b) material proceedings pursuant to which any of our directors, officers or affiliates or any owner of record or beneficial owner of more than 5% of our securities or any associate of any such director, officer or security holder is a party adverse to us or has a material interest adverse to us. ITEM 4. MINE SAFETY DISCLOSURES. We consider health, safety, and environmental stewardship to be a core value of the Company. Pursuant to Section 1503(a) of the United States Dodd-Frank Wall Street Reform and Consumer Protection Act of 2011 (the “Dodd-Frank Act”), issuers that are operators, or that have a subsidiary that is an operator, of a coal or other mine in the United States are required to disclose in their periodic reports filed with the SEC information regarding specified health and safety violations, orders and citations, related assessments and legal actions, and mining-related fatalities under the regulation of the Federal Mine Safety and Health Administration (“MSHA”) under the United States Federal Mine Safety and Health Act of 1977 (the “Mine Act”). During the fiscal year ended December 31, 2022, we had no properties in the United States and were not subject to regulation by the MSHA under the Mine Act and consequently no disclosure is required under Section 1503(a) of the Dodd-Frank Act. 47 PART II ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES. Market and Trading Symbol of Common Shares The Common Shares of Vista Gold are listed on the NYSE American and the Toronto Stock Exchange under the trading symbol “VGZ”.

Exchange Controls There are no governmental laws, decrees or regulations in Canada that restrict the export or import of capital, including foreign exchange controls, or that affect the remittance of dividends, interest, or other payments to non-resident holders of 48 the securities of Vista, other than Canadian withholding tax. See “Certain Canadian Federal Income Tax Considerations for U.S. Residents” below. Certain Canadian Federal Income Tax Considerations for U.S. Residents The following summarizes certain Canadian federal income tax consequences generally applicable under the Income Tax Act (Canada) and the regulations enacted thereunder (collectively, the “Canadian Tax Act”) and the Canada- United States Income Tax Convention (1980) (the “Convention”) to the holding and disposition of Common Shares. Comment is restricted to holders of Common Shares each of whom, at all material times for the purposes of the Canadian Tax Act and the Convention: (i) (ii) (iii) (iv) (v) (vi) (vii) is resident solely in the United States; is entitled to the benefits of the Convention; holds all Common Shares as capital property; holds no Common Shares that are “taxable Canadian property” (as defined in the Canadian Tax Act) of the holder; deals at arm’s length with and is not affiliated with Vista; does not and is not deemed to use or hold any Common Shares in a business carried on in Canada; and is not an insurer that carries on business in Canada and elsewhere; (each such holder, a “U.S. Resident Holder”). Certain U.S.-resident entities that are fiscally transparent for United States federal income tax purposes (including limited liability companies) are generally not themselves entitled to the benefits of the Convention. However, members of, or holders of, an interest in such entities that hold Common Shares may be entitled to the benefits of the Convention for income derived through such entities. Such members or holders should consult their own tax advisors in this regard. Generally, a holder’s Common Shares will be considered to be capital property of the holder provided that the holder is not a trader or dealer in securities, did not acquire, hold or dispose of the Common Shares in one or more transactions considered to be an adventure or concern in the nature of trade and does not hold the Common Shares as inventory in the course of carrying on a business. Generally, a holder’s Common Shares will not be “taxable Canadian property” of the holder at a particular time at which the Common Shares are listed on a “designated stock exchange” (which currently includes the TSX) unless both of the following conditions are met at any time during the 60-month period ending at the particular time: (i) the holder, persons with whom the holder does not deal at arm’s length, or any partnership in which the holder or persons with whom the holder did not deal at arm’s length holds a membership interest directly or indirectly through one or more partnerships, alone or in any combination, owned 25% or more of the issued shares of any class of the capital stock of Vista; and (ii) more than 50% of the fair market value of the Common Shares was derived directly or indirectly from, or from any combination of, real or immovable property situated in Canada, “Canadian resource properties” (as defined in the Canadian Tax Act), “timber resource properties” (as defined in the Canadian Tax Act), or options in respect of or interests in such properties. In certain other circumstances, a Common Share may be deemed to be “taxable Canadian property” for purposes of the Canadian Tax Act. This summary is based on the current provisions of the Canadian Tax Act and the Convention in effect on the date hereof, all specific proposals to amend the Canadian Tax Act and Convention publicly announced by or on behalf of the Minister of Finance (Canada) on or before the date hereof, and the current published administrative and assessing policies of the CRA. It is assumed that all such amendments will be enacted as currently proposed, and that there will be no other material change to any applicable law or administrative or assessing practice, although no assurance can be given in these respects. 49 Except as otherwise expressly provided, this summary does not take into account any provincial, territorial or foreign tax considerations, which may differ materially from those set out herein. This summary is of a general nature only, is not exhaustive of all possible Canadian federal income tax considerations and is not intended to be and should not be construed as legal or tax advice to any particular U.S. Resident Holder. U.S. Resident Holders are urged to consult their own tax advisers for advice with respect to their particular circumstances. The discussion below is qualified accordingly. A U.S. Resident Holder who disposes or is deemed to dispose of one or more Common Shares generally should not thereby incur any liability for Canadian federal income tax in respect of any capital gain arising as a consequence of the disposition. A U.S. Resident Holder to whom Vista pays or is deemed to pay a dividend on the holder’s Common Shares will be subject to Canadian withholding tax, and Vista will be required to withhold the tax from the dividend and remit it to the CRA for the holder’s account. The rate of withholding tax under the Canadian Tax Act is 25% of the gross amount of the dividend (subject to reduction under the provisions of an applicable tax treaty). Under the Convention, a U.S. Resident Holder who beneficially owns the dividend will generally be subject to Canadian withholding tax at the rate of 15 % (or 5%, if the U.S. Resident Holder who beneficially owns the dividend is a company that is not fiscally transparent and which owns at least 10% of the voting stock of Vista) of the gross amount of the dividend. Certain United States Federal Income Tax Considerations for U.S. Residents There may be material tax consequences to U.S. Residents in relation to an acquisition or disposition of Common Shares or other securities of the Company. U.S. Residents should consult their own legal, accounting and tax advisors regarding such tax consequences under United States, state, local or foreign tax law regarding the acquisition or disposition of our Common Shares or other securities, in particular, the tax consequences of the Company likely being a PFIC within the meaning of Section 1297 of the United States Internal Revenue Code. See the section “Item 1A. – Risk Factors – The Company is likely classified as a PFIC, which will likely have adverse U.S. federal income tax consequences for U.S. shareholders” above. Unregistered Sales of Equity Securities None. Repurchase of Securities During 2022, neither Vista nor any affiliate of Vista repurchased Common Shares of Vista registered under Section 12 of the Exchange Act. NYSE American Corporate Governance Section 110 of the NYSE American Company Guide permits the NYSE American to consider the laws, customs and practices of foreign issuers in relaxing certain NYSE American listing criteria, and to grant exemptions from NYSE American listing criteria based on these considerations. A company seeking relief under these provisions is required to provide written certification from independent local counsel that the non-complying practice is not prohibited by home country law. A description of the significant ways in which the Company’s governance practices differ from those followed by domestic companies pursuant to NYSE American standards is as follows: Shareholder Meeting Quorum Requirement: The NYSE American minimum quorum requirement for a shareholder meeting is one-third of the outstanding shares of common stock. In addition, a company listed on the NYSE American is required to state its quorum requirement in its bylaws. The Company’s quorum requirement is set forth in its Articles under the laws of the Province of British Columbia, Canada. Under the Company’s Articles, the quorum for the transaction of business at the meeting is two or more shareholders entitled to vote at the meeting represented in person or by proxy. 50 The foregoing is consistent with the laws, customs and practices in Canada. ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS. The following discussion and analysis should be read in conjunction with our consolidated financial statements for the two years ended December 31, 2022 and 2021, and the related notes thereto, which have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). This discussion and analysis contains forward-looking statements that involve risks, uncertainties, and assumptions. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of many factors, including, but not limited to, those set forth under the section heading “Item 1A. Risk Factors” above and elsewhere in this annual report on Form 10-K. See section heading “Note Regarding Forward-Looking Statements” in this annual report on Form 10-K. All dollar amounts stated herein are in U.S. dollars in thousands, unless specified otherwise, except per share-related amounts. References to A$ refer to Australian currency and USD or $ to United States currency. The scientific and technical disclosures about Mt Todd in this discussion and analysis have been reviewed and approved by John W. Rozelle, Senior Vice President of Vista. Mr. Rozelle is a qualified person as defined by subpart 1300 of Regulation S-K (“S-K 1300”) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Canadian National Instrument 43- 101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). Overview Vista Gold Corp. and its subsidiaries (collectively, “Vista,” the “Company,” “we,” “our,” or “us”) operate in the gold mining industry. We are focused on evaluation, acquisition, exploration and advancement of gold exploration and potential development projects, which may lead to gold production or value adding strategic transactions such as earn-in right agreements, option agreements, leases to third parties, joint venture arrangements with other mining companies, or outright sales of assets for cash and/or other consideration. We look for opportunities to improve the value of our gold projects through exploration drilling and/or technical studies focused on optimizing previous engineering work. We do not currently generate cash flows from mining operations. The Company’s flagship asset is its 100% owned Mt Todd gold project (“Mt Todd” or the “Project”) in Northern Territory, Australia (“NT”). With the approval of the Mining Management Plan (“MMP”) in June 2021, all major operating and environmental permits for Mt Todd have been received. Mt Todd is one of the largest and most advanced undeveloped gold projects in Australia. In 2022, Vista completed a feasibility study for Mt Todd (“Mt Todd FS”), retained CIBC Capital Markets as a strategic advisor to support the Company’s strategic outreach process for Mt Todd, concluded a drilling program to demonstrate district-scale resource growth potential, and significantly reduced costs. These accomplishments advanced Mt Todd’s reserve size, resource growth potential, economic returns, and overall attractiveness as a large, development ready gold project. The Mt Todd FS demonstrates the potential of a large-scale gold project at Mt Todd. Highlights include: • • • • • estimated proven and probable mineral reserves increased by 19% to 6.98 million ounces of gold (280 Mt at 0.77 g Au/t) using a gold price of $1,125 for the reserve estimate and a cut-off grade of 0.35 g Au/t(1)(2); average annual production of 395,000 ounces of gold over a 16-year mine life at an average cash cost of $817 per ounce; high capital efficiency, with initial capital requirements of $892 million, or $141 per payable ounce of gold; after-tax NPV5% of $999.5 million and internal rate of return (“IRR”) of 20.6% at a gold price of $1,600 per ounce; and after-tax NPV5% of $1.7 billion and IRR of 29.4% at a price of $1,900 per ounce of gold. 51 (1) Note to investors: Proven and probable mineral reserves are estimated in accordance with S-K 1300 and CIM Definition Standards (as defined below). (2) See “Item 2. Properties – Mt Todd Gold Project, Northern Territory, Australia – Mineral Resources and Mineral Reserve Estimates” in this annual report on Form 10-K for additional information. The Mt Todd FS included reserve estimates pursuant to subpart 1300 of Regulations S-K (“S-K 1300”) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Canadian Institute of Mining Metallurgy and Petroleum Definition Standards for Mineral Resources and Mineral Reserves (“CIM Definition Standards”) based on mine plans developed using a gold price in line with the current market conditions at the time of the study. The Mt Todd FS addressed recommendations from the 2019 pre-feasibility study, included minor updates of the Project design to be consistent with the MMP, and reflected the completion of engineering and detailed costing in all areas of the Project. We have invested over $110 million to systematically explore, evaluate, engineer, permit and de-risk Mt Todd since we acquired it in 2006. In recent years, we completed a number of optimization studies, which were incorporated into the Mt Todd FS. This work has added substantial value to the Project and positions Mt Todd for near-term development. The strategic process with CIBC Capital Markets, which is ongoing and remains a top priority, continues to generate interest and positive feedback on the technical merits of Mt Todd. The Company believes that there are indications that market conditions are improving, but interested parties continue to maintain a cautious approach to new, large-scale development projects. To address this, the Company is evaluating a smaller scale project with significantly lower initial capital costs while maintaining operating costs similar to those in the Mt Todd FS, with potential for subsequent throughput expansion or mine-life extension. We expect to be able to demonstrate this alternate development strategy early in 2023 and believe this should attract the interest of new potential partners and those who have previously expressed interest in different development strategies. In 2022, the Company completed an exploration drilling program within a 5.4 km trend extending immediately north from the Batman pit. The Company believes that the results from this program and historical sources demonstrate excellent resource growth potential, including delineation of four highly prospective exploration targets. The Company views these targets as positive indicators of future resource growth potential to interested parties, and believes these targets represent the closest and most immediate opportunity for growth with the appropriate investment in additional drilling. Vista has no immediate plans to complete additional drilling but continues to advance exploration on the exploration licenses, which cover 1,650 km2. We significantly reduced our 2022 recurring costs, which were approximately 15% below plan. Reducing costs and maximizing cost effectiveness are also high priorities for 2023. We have already taken steps to further reduce recurring costs by approximately 7% during 2023 and continue to evaluate and implement opportunities for additional cost reductions. In addition to the technical advancements of the Project in 2022, Vista has all major operating and environmental permits for the development of Mt Todd. We have invested significant resources in water treatment and management, environmental, and social programs. We believe this has benefited our relationships with the traditional landowners, local communities, and Northern Territory, Australia, creating a strong social license. Mineral Resources and Mineral Reserves Estimates The following table presents the estimated mineral resources for the Project. The following mineral resources and mineral reserves were prepared in accordance with both S-K 1300 standards and CIM Definition Standards. 52 Mt Todd Gold Project – Summary of Gold Mineral Resources based on US$1,300/oz Gold Batman Deposit Heap Leach Pad Quigleys Deposit Total Tonnes (000s) Grade (g Au/t) Contained Ounces (000s) Tonnes (000s) Grade (g Au/t) Contained Ounces (000s) Tonnes (000s) Grade (g Au/t) Contained Ounces (000s) Tonnes (000s) Grade (g Au/t) Contained Ounces (000s) — 10,816 — 1.76 — 613 — — — — — — 594 7,301 1.15 1.11 22 260 594 18,117 1.15 1.49 10,816 1.76 613 61,323 0.72 1,421 — — — — — — 7,895 1.11 3,981 1.46 282 187 18,711 1.49 65,304 0.77 22 873 895 1,608 Measured Indicated Measured & Indicated Inferred Notes: • Measured & indicated resources exclude proven and probable reserves. • The Point of Reference for the Batman and Quigleys deposits is in situ at the property.

The effective date of the Batman Deposit, Heap Leach Pad, and Quigleys Deposit mineral resources estimates under the requirements of SK-1300 is December 31, 2022. There have been no changes in the mineral resource estimates since December 31, 2021 because upon review the Company and the relevant qualified persons determined that the same material assumptions and estimates, including all economic parameters for resource estimation purposes, continued to apply as of December 31, 2022. The effective date of the Batman Deposit, Heap Leach Pad, and Quigleys Deposit mineral resource estimates under the requirements of NI 43-101 is December 31, 2021. • Mineral resources that are not mineral reserves have no demonstrated economic viability and do not meet all relevant modifying factors. There was no change in resource estimates as of December 31, 2022 compared to December 31, 2021 as the same material assumptions and criteria were determined to continue to apply to the resource estimates and there was no conversion of resources into reserves in the fiscal year ending December 31, 2022. 53 Mt Todd Gold Project – Summary of Gold Mineral Reserves based on 50,000 tpd, 0.35 g Au/t cut-off and $1,125 per Ounce Pit Design Batman Deposit Heap Leach Pad Total Tonnes (000s) Grade Ounces (000s) (g Au/t) Tonnes Grade Ounces (000s) (g Au/t) (000s) Tonnes (000s) Grade Ounces (000s) (g Au/t) Contained Contained Contained Proven Probable Proven & Probable Economic analysis conducted only on proven and probable mineral reserves. 81,277 185,744 267,021 2,192 4,555 6,747 0.84 0.76 0.79 — 13,354 13,354 — 0.54 0.54 — 232 232 81,277 199,098 280,375 0.84 0.75 0.77 2,192 4,787 6,979 Notes: • • • Deepak Malhotra is the QP responsible for reporting the heap-leach pad reserves. • Thomas L.

Because all the heap-leach pad reserves are to be fed through the mill, these reserves are reported without a cutoff grade applied. The reserves point of reference is the point where material is fed into the mill. The effective date of the mineral reserve estimates under the requirements of S-K 1300 is December 31, 2022. There have been no changes in the mineral reserve estimates since December 31, 2021 because the Company and the relevant qualified persons determined that the same material assumptions and criteria continued to apply as of December 31, 2022, including that the Company used a cutoff grade higher than the economic cutoff grade such that any intervening changes in the underlying economic assumptions were not material and did not require use of a cutoff grade greater than 0.35 g Au/t for mineral reserve estimation purposes. The effective date of the mineral reserve estimates under the requirements of NI 43-101 is December 31, 2021. • • • There was no change in reserve estimates as of December 31, 2022 compared to December 31, 2021 as the same material assumptions and criteria were determined to continue to apply to the reserve estimates and there was no depletion of reserves in the fiscal year ending December 31, 2022 as the Mt. Todd Gold Project is in the development stage Cautionary note to investors: Proven and probable mineral reserves are estimated in accordance with each of S-K 1300 and CIM Definition Standards. A number of risk factors may adversely affect estimated mineral reserves and mineral resources, any of which may result in a reduction or elimination of reported mineral reserves and mineral resources. See “Item 1A. Risk Factors.” Results from Operations Summary Consolidated net loss for the year ended December 31, 2022 was $4,931, or $0.04 per common share in the capital of Vista (each, a “Common Share”) on both a basic and diluted basis. Consolidated net loss for the year ended December 31, 2021 was $15,237, or $0.14 per Common Share on both a basic and diluted basis. The principal components of our 2022 net loss and the year-over-year changes are discussed below. The Company had cash of $8,110, working capital of $7,714, and no debt as of December 31, 2022. Gain on Disposal of Mineral Property Interests, Net In January 2022, the Company received $2,500 to cancel the remaining 1% net smelter return royalty at the Awak Mas project in Indonesia. Including recognition of the associated deferred option gain, the Company recognized a gain of $2,883 upon receipt of the payment. 54 In January and June 2021, the Company received a total of $2,100 for cancellation of its royalty interests and back-in right in the Guadalupe de los Reyes gold and silver project in Sinaloa, Mexico (“Los Reyes”). The January 2021 payment of $1,100 was initially recorded as deferred option gain, with the full $2,100 being recognized as a gain upon receipt of the second payment of $1,000 in June 2021. Exploration, Property Evaluation and Holding Costs Exploration, property evaluation and holding costs, including fixed costs, discretionary programs, and non-cash stock- based compensation, were $4,522 and $7,942 during the years ended December 31, 2022 and 2021, respectively. These costs were predominantly associated with Mt Todd and were comprised of fixed costs and discretionary costs. For the years ended December 31, 2022 and 2021, our fixed exploration, property evaluation and holding costs totaled $3,095 and $3,855, respectively. These costs included expenditures necessary to preserve our property rights and meet our safety, regulatory and environmental responsibilities. The principal components of the decrease in 2022 included lower personnel costs and reduced power consumption due to minimal water pumping. Expenses incurred for 2022 Mt Todd discretionary programs totaled $1,427. The discretionary programs include $489 for completing the Mt Todd FS and $413 for exploration drilling, plus additional staffing expenses to support drilling and other activities. Expenses incurred for 2021 Mt Todd discretionary programs totaled $4,087. The discretionary programs include $2,232 for preparing the Mt Todd FS and $1,702 for exploration drilling, plus additional staffing expenses to support drilling and other activities. Included in the 2022 and 2021 exploration, property evaluation and holding costs were non-cash stock-based compensation of $262 and $354, respectively. Corporate Administration Corporate administration costs were $3,767 and $3,945 during the years ended December 31, 2022 and 2021, respectively. The 2022 and 2021 corporate administration costs included non-cash stock-based compensation of $517 and $533, respectively. Costs were generally lower during 2022 due to lower personnel and investor relations expenses, partially offset by higher legal and travel costs. 2021 Write-down of Plant and Equipment During the year ended December 31, 2021, the Company reduced the carrying value of the used mill equipment to $nil based on management’s estimate of recoverability. This estimate reflects management’s consideration of the duration this equipment has been actively marketed by an independent broker and the current competitive market conditions for used equipment yielding no sales. These inputs used in valuing our used mill equipment involved a high degree of subjectivity and resulted in management not having the ability to estimate recoverable sales proceeds with sufficient certainty. The Company recorded this reduction as an operating loss of $5,500 in our Consolidated Statements of Income/(Loss). The used mill equipment continues to be marketed by the independent broker. Non-Operating Income and Expenses Other Income Other Income was $409 and $50 for the years ended December 31, 2022 and 2021, respectively. In 2022, the Company reviewed and reversed a previously accrued amount of $240 for contingent reclamation costs because the associated costs were neither probable nor could be reasonably estimated. The Company also received cash of $196 in May 2022 as a value-added tax recovery from the previous sale of a non-core asset. 55 Financial Position, Liquidity and Capital Resources Operating Activities Net cash used in operating activities was $7,413 and $10,620 for the years ended December 31, 2022 and 2021, respectively. The decrease in operating cash outflows in 2022 largely resulted from lower spending for drilling, partially offset by higher payments for the feasibility study. Investing Activities Net cash provided by investing activities of $2,879 for the year ended December 31, 2022 resulted primarily from the $2,500 final payment for the Awak Mas royalty cancellation and receipt of $384 upon maturity of short-term investments. Net cash provided by investing activities of $2,631 for the year ended December 31, 2021 resulted primarily from receipt of $2,100 under the Los Reyes agreement, $339 from the sale of Nusantara Resources shares, and $315 for payments related to Awak Mas, offset by fixed asset purchases of $139. Financing Activities Net cash of $113 for the year ended December 31, 2022 was used in financing activities by payments of $357 for employee withholding tax obligations in lieu of issuing Common Shares, partially offset by net proceeds of $244 under the ATM Program (as defined below). Net cash of $12,984 for the year ended December 31, 2021 was provided by net proceeds of $12,323 from the Company’s July 2021 public offering (“2021 Offering”) (as described below) and $1,062 under the ATM Program (which included $191 relating to sales in 2020 that settled for cash in January 2021), partially offset by payments of $401 for employee withholding tax obligations in lieu of issuing Common Shares. Liquidity and Capital Resources The Company considers available cash, cash equivalents and short-term investments to be its primary measure of liquidity. These capital resources totaled $8,110 at December 31, 2022 compared to $13,141 at December 31, 2021, representing a net decrease of $5,031 during 2022. Current assets net of current liabilities (“Working Capital”) is a secondary measure of liquidity for the Company. As of December 31, 2022 and 2021, working capital was $7,714 and $12,164, respectively. These amounts were net of deferred option gain of $nil and $383, respectively. The deferred option gain was recognized as income during 2022 and did not require any use of current assets. Consequently, the components of working capital affecting Vista’s liquidity and capital resources included: Current Assets Offset by accounts payable and accrued liabilities At December 31, 2022 At December 31, 2021 13,952 $ (1,405) $ 8,647 (933) $ $ During 2022, the Company benefited from cash inflows of $2,500 for cancellation of the Awak Mas royalty, ATM Program proceeds of $244 as discussed below, and a $196 value-added tax recovery from the previous sale of non-core assets. These sources of cash were offset by operating cash outflows of $7,413 and other expenditures of $362. Recurring costs included in operating cash outflows were planned to be approximately $7,000 for 2022, but the Company implemented cost reduction measures that resulted in actual recurring costs being approximately 15% lower than plan. This represented savings of approximately $1,000. Additional details regarding 2022 financial results are presented in the “Results from Operations” section above and the preceding discussions in this section of operating activities, investing activities and financing activities. For 2023, the Company plans to implement additional measures to reduce annual recurring costs to approximately $5,500. Discretionary programs are also expected to be reduced to approximately $600. The Company is continuing to evaluate opportunities to lower ongoing costs. 56 In addition to Vista’s existing capital resources, we are a party to an at-the-market offering agreement (the “ATM Agreement”) with H. C. Wainwright & Co., LLC (“Wainwright”) to provide balance sheet flexibility at a potentially lower cost than other means of equity issuances. Under the ATM Agreement, the Company has the right, but is not obligated, to issue and sell Common Shares through Wainwright for aggregate sales proceeds of up to $10,000 (the “ATM Program”). During 2022, the Company sold 401,884 Common Shares under the ATM Program for net proceeds of $244. As of December 31, 2022, $9,748 remained available under the ATM Program. Offers or sales of Common Shares under the ATM Program will be made only in the United States in an “at the market offering” as defined in Rule 415 under the United States Securities Act of 1933, as amended, subject to an effective registration statement under the U.S. Securities Act of 1933, as amended, and no offers or sales of Common Shares under the ATM Agreement will be made in Canada. The Common Shares will be distributed at market prices prevailing at the time of sale. The Company could also undertake a private placement or public offering to raise additional cash. The most recent such financing was in July 2021, when Vista completed the 2021 Offering of 12,272,730 units (the “Units”) for net proceeds of $12,323. Each Unit consisted of one Common Share in the capital of the Company and one-half of one Common Share purchase warrant (each full warrant, a “Warrant”). Each Warrant entitles the holder to purchase one Common Share at a price of $1.25 per Common Share (subject to adjustment in certain circumstances) and is exercisable until July 12, 2024. See footnote 6 to the accompanying financial statements for more details on the 2021 Offering. Net proceeds from the 2021 Offering were used for additional exploration drilling and to complete the Mt Todd FS. The remaining proceeds are being used for working capital requirements and/or for other general corporate purposes, which include ongoing regulatory, legal and accounting expenses, management and administrative expenses, and other corporate initiatives. Other potential sources of cash inflows may include monetization of Vista’s remaining non-core assets, which include a royalty interest in the U.S. and used mill equipment that is being marketed by a third-party mining equipment dealer. Cash may also be available to Vista through several forms of financial instruments, such as a royalty or stream interest in Mt Todd, convertible instruments, and debt facilities. Considering current economic conditions and the Company’s ongoing initiatives, we believe our cash, cash equivalents and short-term investments and Working Capital as of December 31, 2022, together with other potential future sources of financing and sales of non-core assets, will be sufficient to fund our currently planned corporate expenses, Mt Todd holding costs, and anticipated discretionary programs for at least one year from the date of issuance of this annual report on Form 10-K. Vista’s long-term viability depends upon our ability to realize value from our principal asset, Mt Todd. Our primary objective is to maintain adequate liquidity as we seek to preserve, enhance and realize value from Mt Todd in order to achieve positive returns for our shareholders. Our funding strategy is to maintain a low expenditure profile, realize value from our remaining non-core assets and, when necessary, issue additional equity or find other means of financing. The underlying value and recoverability of the amounts shown as mineral properties and plant and equipment as presented in our Condensed Consolidated Balance Sheets depend on market and industry conditions, our ability to attract sufficient capital resources to execute our strategy, and the ultimate success of our programs to enhance and realize value at Mt Todd. Off-Balance Sheet Arrangements We have no off-balance sheet arrangements required to be disclosed in this annual report on Form 10-K. 57 Summary of Quarterly Results 2022 Revenue Net income/(loss) Basic income/(loss) per share 2021 Revenue Net income/(loss) Basic income/(loss) per share 4th quarter 3rd quarter 2nd quarter 1st quarter $ $ $ $ $ $ — (1,495) (0.01) — (8,316) (0.08) $ $ $ $ $ $ — (1,692) (0.02) — (3,069) (0.02) $ $ $ $ $ $ — (1,424) (0.01) — (753) (0.01) $ $ $ $ $ $ — (320) (0.00) — (3,099) (0.03) Critical Accounting Estimates and Recent Accounting Pronouncements Critical Accounting Estimates Critical accounting estimates are accounting estimates that involve a significant level of estimation uncertainty and have had or are reasonably likely to have a material impact on the financial condition or results of operations of the Company. Management has identified the following critical accounting estimates. See Note 2 to our consolidated financial statements contained in “Part II. Item 8. Financial Statements and Supplementary Data” for additional accounting policies and estimates. Impairment Assessment of Long-Lived Assets Our long-lived assets are evaluated for impairment when information becomes available indicating that the carrying value may not be recoverable. Assumptions and estimates considered in valuing our mineral properties included management’s expectations for the price of gold, foreign exchange rates, costs to build and operate the mine, and projected cash flows. These assumptions are subjective and subject to a range of uncertainties. A feasibility study reduces the uncertainty around some assumptions to an acceptable level and is a primary source of evidence. Stock-Based Compensation Our stock plans include awards that vest based on performance criteria. Stock-based compensation expense for these awards is estimated quarterly, including adjustments to previous recognized expense, based on anticipated achievement of performance criteria. The quarterly estimated vesting percentage reflects management’s assessment of progress in accomplishing defined corporate objectives. Upon vesting, current period expense is adjusted based on the actual achievement of performance criteria. Income Taxes We have assets, hold interests, and conduct activities in several countries and are subject to their tax regimes. Tax laws are complex and continue to evolve. While we have a history of losses, our assumptions made in tax returns are subject to review and interpretation by taxing authorities and could be modified. Our critical tax estimates include timing of future income, deductibility of expenses, sustainability of tax positions, valuation allowances on deferred tax assets, and allocation of expenses between companies. Recent Accounting Pronouncements See Note 2 to our consolidated financial statements contained in “Part II. Item 8. Financial Statements and Supplementary Data” for recent accounting pronouncements applicable to the Company. 58 Non-U.S. GAAP Financial Measures In this report, we have provided information prepared or calculated according to U.S. GAAP, as well as provided certain non-U.S. GAAP prospective financial performance measures. Because the non-U.S. GAAP performance measures do not have standardized meanings prescribed by U.S. GAAP, they may not be comparable to similar measures presented by other companies. These measures should not be considered in isolation or as substitutes for measures of performance prepared in accordance with U.S. GAAP. There are limitations associated with the use of such non-U.S. GAAP measures. Since these measures do not incorporate revenues, changes in working capital and non-operating cash costs, they are not necessarily indicative of potential operating profit or loss, or cash flow from operations as determined in accordance with U.S. GAAP. The non-U.S. GAAP measures associated with Cash Costs, All-in Sustaining Costs (“AISC”) and resulting per ounce and per tonne processed metrics are not, and are not intended to be, presentations in accordance with U.S. GAAP. These metrics represent costs and unit-cost measures related to the Project. We believe that these metrics help investors understand the economics of the Project. We present the non-U.S. GAAP financial measures for our Project in the tables below. Actual U.S. GAAP results may vary from the amounts disclosed in this report. Other companies may calculate these measures differently. Cash Costs, AISC and Respective Unit Cost Measures Cash Costs and AISC, and respective unit cost measures, are non-U.S. GAAP metrics developed by the World Gold Council to provide transparency into the costs associated with producing gold and provide a standard for comparison across the industry. The Company reports Cash Costs and AISC on a per ounce and per tonne processed basis because we believe these metrics more appropriately reflect mining costs over specified periods and the life of mine. Similar metrics are widely used in the gold mining industry as comparative benchmarks of performance. Cash Costs consist of Project operating costs, refining costs, and the Jawoyn Association royalty. The sum of these costs is divided by the corresponding payable gold ounces or tonnes processed to determine Cash Cost per ounce or per tonne processed metrics, respectively. AISC consists of Cash Costs (as described above), plus sustaining capital costs. The sum of these costs is divided by the corresponding payable gold ounces or tonnes processed to determine AISC per ounce or per tonne processed metrics, respectively. Other costs excluded from Cash Costs, and AISC include depreciation and amortization, income taxes, government royalties, financing charges, costs related to business combinations, asset acquisitions other than sustaining capital, and asset dispositions. The following tables demonstrate the calculation of Cash Costs, AISC, and the respective unit-cost metrics for amounts presented in this report.

FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA. Management’s Report on Internal Control Over Financial Reporting The management of Vista Gold Corp. and its subsidiaries (collectively, “Vista,” the “Company,” “we,” “our,” or “us”) is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed by, or under the supervision of, the Company’s principal executive and principal financial officers and effected by the Company’s board of directors (the “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. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. The Company’s management assessed the effectiveness of the Company’s internal control over financial reporting at December 31, 2022. In making this assessment, the Company’s management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission Internal Control-Integrated Framework in 2013. Based upon its assessment, management concluded that, at December 31, 2022, the Company’s internal control over financial reporting was effective. 61 Report of Independent Registered Public Accounting Firm To the Shareholders and Board of Directors of Vista Gold Corp. Opinion on the Financial Statements We have audited the accompanying consolidated balance sheets of Vista Gold Corp. (the “Company”) as of December 31, 2022 and 2021, the related consolidated statements of income/(loss), shareholders' equity, and cash flows for each of the years in the two-year period ended December 31, 2022, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2022, in conformity with accounting principles generally accepted in the United States of America. Basis for Opinion The Company's management is responsible for these financial statements. Our responsibility is to express an opinion on the Company’s 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 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 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matter The critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. We determined that there are no critical audit matters. /s/ PLANTE & MORAN, PLLC We have served as the Company’s auditor since 2014. Denver, Colorado February 23, 2023 62 VISTA GOLD CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Dollar amounts in U.S. dollars and in thousands, except share-related amounts) 1. Nature of Operations Vista Gold Corp. and its subsidiaries (collectively, “Vista,” the “Company,” “we,” “our,” or “us”) operate in the gold mining industry. We are focused on acquisition, exploration and advancement of gold exploration and potential development projects, which may lead to gold production or value adding strategic transactions such as earn-in right agreements, option agreements, leases to third parties, joint venture arrangements with other mining companies, or outright sales of assets for cash and/or other consideration. We look for opportunities to improve the value of our gold projects through exploration drilling and/or technical studies focused on optimizing previous engineering work. We do not currently generate cash flows from mining operations. The Company’s flagship asset is its 100% owned Mt Todd gold project (“Mt Todd” or the “Project”) in Northern Territory, Australia. Mt Todd is one of the largest undeveloped gold projects in Australia. With the approval of the Operational Mining Management Plan in June 2021, all major operating and environmental permits for Mt Todd have been received. Since acquiring Mt Todd in 2006, we have invested substantial financial resources to systematically explore, evaluate, engineer, permit and de-risk the Project. In February 2022, we completed a feasibility study for Mt Todd. In March 2022, we appointed CIBC Capital Markets as our strategic advisor, and we are advancing a strategic process to seek a partner or other form of transaction for Mt Todd. References to $ are to United States dollars and A$ are to Australian dollars. 2. Significant Accounting Policies and Estimates Principles of Consolidation The Consolidated Financial Statements include the accounts of Vista and its subsidiaries, all of which are 100%-owned subsidiaries, either directly or indirectly through a subsidiary, and under Vista’s control. All significant intercompany balances and transactions have been eliminated. The Consolidated Financial Statements have been prepared in accordance with U.S. GAAP. Use of Estimates Preparation of the Company’s Consolidated Financial Statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, income, and expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions are: asset impairments, the fair value and accounting treatment of financial instruments including warrants; valuation allowances for deferred tax assets; the fair value and accounting treatment of stock-based compensation; and the provision for environmental liabilities. Management based its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Accordingly, actual results will differ from amounts estimated in these financial statements. Cash and Cash Equivalents Cash and cash equivalents include cash on hand and government securities with original maturities of 90 days or less when purchased. Foreign Currency Transactions Our functional currency is the U.S. dollar. Foreign currency transactions denominated in currency other than the functional currency are recorded at the approximate rate of exchange at the transaction date and any gains/(losses) resulting therefrom are recorded in other expense. For each of the years ended December 31, 2022 and 2021, net foreign currency gains/(losses) were insignificant. 67 Short-term Investments Short-term investments consist of securities with original maturity dates greater than 90 days and less than one year. These securities are typically United States or Australian government treasury bills and/or notes. Short-term investments are recorded at amortized cost and are classified as debt securities held-to-maturity as the Company has the intention and ability to hold these instruments until their original maturity date at the time of purchase. Mineral Properties Mineral property acquisition costs, including directly related costs, are capitalized when incurred. After acquisition of a mineral property, associated exploration and evaluation costs are expensed as incurred until development commences. Development costs to establish access to mineral reserves reported in accordance with subpart 1300 of Regulation S-K under the Securities Exchange Act of 1934, as amended, and other preparations leading to commercial production would be capitalized following a decision by the Company to develop such mineral property. Capitalization of development costs would conclude upon commencement of sustainable production. Capitalized costs associated with a mineral property will be amortized using the units-of-production method over the estimated life of mineral reserves once sustainable production is achieved. If mineral properties are subsequently sold or abandoned, any unamortized costs will be charged to expense in that period. The recoverability of the carrying values of our mineral properties is dependent upon economic reserves being discovered or developed on the properties, permitting, financing, start-up, and profitable commercial production from, or the sale/lease of, or other strategic transactions related to these properties. Development and/or start-up of mineral properties will depend on, among other things, management’s ability to raise sufficient capital for these purposes. Any proceeds received from option or sale agreements are ascribed to recovery of the carrying value of the related project until the carrying value reaches zero. Thereafter, any additional proceeds received are recognized as a contract liability (deferred option gain) until control has transferred to the buyer or the related contract terminates. We assess the carrying value of mineral properties for impairment whenever information or circumstances indicate the potential for impairment. This would include events and circumstances such as our inability to obtain all the necessary permits, changes in the legal status of our mineral properties, government actions, the results of exploration activities and technical evaluations, and changes in economic conditions, including the price of gold and other commodities or input prices. Such evaluations compare estimated future net cash flows with our carrying costs and future obligations on an undiscounted basis. If it is determined that the estimated future undiscounted cash flows are less than the carrying value of the property, a write-down to the estimated fair value will then be reported in our Consolidated Statement of Income/(Loss) for the period. Where estimates of future net cash flows are not determinable and where other conditions indicate the potential for impairment, management uses available market information and/or other sources to assess if the carrying value can be recovered and to estimate fair value. Impairment Carrying values of long-lived assets, other than mineral properties, are evaluated for impairment when information becomes available that indicates the carrying value may not be recoverable. If it is determined that the fair value is less than the carrying value an impairment charge equal to the difference between the fair value and the carrying value will be recorded in our Consolidated Statements of Income/(Loss). Stock-Based Compensation Under our stock option, long-term incentive, and deferred share unit plans, the Company can grant stock incentive options, restricted share units, and deferred share units to executives, employees, consultants, and non-employee directors as applicable. Compensation expense for such grants is recorded in the Consolidated Statements of Income/(Loss) as a component of exploration, property evaluation and holding costs and corporate administration, with a corresponding increase to Common Shares in the Consolidated Balance Sheets. The fair value of option grants is calculated using the Black-Scholes option pricing model. The fair value of restricted and deferred share units is based on the closing price of 68 our Common Shares on the grant date, or, in certain cases, amounts determined by a Brownian motion pricing model. The expense is based on the fair value of the grant on the grant date and is recognized over the vesting period specified for each grant. Forfeitures of unvested awards for all stock-based compensation result in expense reversal upon forfeiture. Fair Value of Financial Instruments Our financial instruments include cash and cash equivalents, marketable securities, short-term investments, accounts payable, and certain other current assets and liabilities. Due to the short-term nature of these financial instruments, carrying amounts approximate fair value. Recent Accounting Pronouncements No recent accounting pronouncements are applicable to Vista at this time. 3. Other Investments Short-term investments As of December 31, 2022 and 2021, the amortized cost basis of our short-term investments was $nil and $384, respectively. The amortized cost basis approximates fair value at December 31, 2021. Short-term investments at December 31, 2021 were comprised of Australian Government instruments, all of which had maturity dates greater than 90 days but less than one year. Other investments The Company held 1,333,334 shares of Nusantara Resources Limited (“Nusantara Resources”) during 2021. On September 22, 2021, the shareholders of Nusantara Resources approved a scheme of arrangement whereby PT Indika Mineral Investindo (“Indika”) offered to acquire all issued shares of Nusantara Resources for A$0.35 per share. The transaction closed on October 6, 2021, resulting in Vista receiving $339 upon tendering its Nusantara Resources shares. Investments in marketable securities are recorded at fair value in the Consolidated Balance Sheets. Subsequent changes in fair value are recorded in the Consolidated Statements of Income/(Loss) in the period in which they occur. The following table summarizes our investments in marketable securities as of December 31, 2022 and 2021. Fair value at beginning of period Nusantara Resources shares sold Realized gain Fair value at end of period 4. Mineral Properties Mt Todd, Northern Territory, Australia Capitalized mineral property values were: Mt Todd, Australia Guadalupe de los Reyes, Sinaloa, Mexico December 31, 2022 December 31, 2021 $ $ — — — — $ $ 293 (339) 46 — At December 31, 2022 At December 31, 2021 2,146 $ 2,146 $ In July 2020, the Company sold the Guadalupe de los Reyes gold and silver project in Sinaloa, Mexico (“Los Reyes”) to Prime Mining Corporation (“Prime Mining”). As part of the terms of sale, Prime Mining was required to make additional payments to Vista of $2,100 in lieu of Vista being granted certain royalty and back-in rights. Prime Mining paid $1,100 in 69 January 2021 and $1,000 in June 2021. Having received these payments as scheduled, Vista has no remaining right to be granted the royalties and back-in right, and Vista recognized a gain on disposal of mineral property interests of $2,100 during the year ended December 31, 2021. Awak Mas, Sulawesi, Indonesia Vista held a net smelter return royalty (“NSR”) on the Awak Mas project in Indonesia (“Awak Mas”). Previously, Vista and the holder of Awak Mas amended the original NSR agreement to allow the holder or a nominated party to make certain payments to Vista to cancel the original NSR. The holder of the Awak Mas royalty made the final $2,500 payment in January 2022. The Company recognized a gain of $2,883 for this final payment, which included recognition of $383 that was carried as deferred option gain as of December 31, 2021. With this final payment, the Company has no remaining royalty interest in Awak Mas. 5. Plant and Equipment December 31, 2022 Accumulated Depreciation Cost Net Cost December 31, 2021 Accumulated Depreciation Mt Todd, Australia Corporate, United States Used mill equipment, Canada $ $ 5,364 $ 333 — 5,697 $ 5,171 333 — 5,504 $ $ 193 $ — — 193 $ 5,359 $ 333 — 5,692 $ 5,126 333 — 5,459 $ $ Net 233 — — 233 During the year ended December 31, 2021, the Company reduced the carrying value of the used mill equipment to $nil to reflect management’s estimate of recoverability. The Company recorded this reduction as an operating loss of $5,500 in our Consolidated Statements of Income/(Loss). The inputs used to value the used mill equipment included the duration this equipment has been actively marketed by an independent broker, and the current competitive market conditions for used equipment yielding no sales. Such inputs involved a high degree of subjectivity and resulted in management not having the ability to estimate recoverable sales proceeds with sufficient certainty. The used mill equipment continues to be marketed by the independent broker. 6. Common Shares Equity Financing During July 2021, we closed a public offering of 12,272,730 units (the “Units”) for net proceeds of $12,323 (the “2021 Offering”). The stock issuance costs associated with the 2021 Offering were $1,177. Each Unit consisted of one common share of the Company (each a “Common Share”) and one-half of one Common Share purchase warrant (each full warrant, a “Warrant”). A total of 7,408,101 Warrants were issued, including 920,454 Warrants purchased by the underwriters pursuant to an overallotment option and 351,282 broker Warrants issued to the underwriters as compensation. Each Warrant entitles the holder thereof to purchase one Common Share at a price of $1.25 per Common Share (subject to adjustment in certain circumstances) and is exercisable for a period of 36 months from the closing of the 2021 Offering. The Warrants, which are classified as equity, had an aggregate relative fair value of $1,991 upon the issuance thereof on the closing date. The relative fair value of Warrants was estimated at the grant date using the Black-Scholes option pricing model using the following assumptions: 1) expected volatility of 70.6%, 2) risk-free rate of 0.43%, 3) contractual term of 3 years, and 4) stock price on the closing date of $0.89 per Common Share. A relative fair value of $11,509 was allocated to the Common Shares. Vista is party to an at-the-market offering agreement (the “ATM Agreement”) with H. C. Wainwright & Co., LLC (“Wainwright”), under which the Company has the right, but was not obligated, to issue and sell Common Shares through 70 Wainwright for aggregate sales proceeds of up to $10,000 (the “ATM Program”). No securities can be offered in Canada under the ATM Agreement. As of December 31, 2022, $9,748 remained available under the ATM Program. During the year ended December 31, 2022 the Company sold 401,884 Common Shares for net proceeds of $244 under the ATM Program. During the year ended December 31, 2021 the Company sold 798,270 Common Shares for net proceeds of $871 under the ATM Program, which excluded $191 that settled for cash in January 2021. Each sale under the ATM Agreement was made pursuant to an “at the market offering” as defined in Rule 415 under the United States Securities Act of 1933, as amended. Other Share Issuances During the years ended December 31, 2022 and 2021 we issued 889,762 and 946,328 Common Shares, respectively, in connection with vesting of restricted share units (“RSUs”). Warrants Warrant activity is summarized in the following table. Intrinsic value is the aggregate value of warrants that were in the money at the end of the period. The warrants are subject to standard anti-dilution provisions. Weighted Average Weighted Average As of December 31, 2020 Issued As of December 31, 2021 As of December 31, 2022 Stock-Based Compensation Exercise Price Remaining Life Warrants Outstanding Per Share — — $ 1.25 1.25 1.25 7,408,101 7,408,101 $ 7,408,101 $ (Years) — 3.0 2.5 1.5 The Company’s stock-based compensation plans include: RSUs currently outstanding under the Company’s long-term equity incentive plan (“LTIP”), deferred share units (“DSUs”) issuable pursuant to the Company’s deferred share unit plan (“DSU Plan”) and stock options (“Stock Options”) issuable under the Company’s stock option plan (the “Plan”). Stock- based compensation may be issued to our directors, officers, employees and consultants. The maximum number of Common Shares that may be reserved for issuance under the combined stock-based compensation plans is a variable number equal to 10% of the issued and outstanding Common Shares on a non-diluted basis at any one time. Vista also issued phantom units in 2018 to be settled in cash over a three-year term. Stock-based compensation and phantom units may be granted from time to time at the discretion of the Board of Directors of the Company (the “Board of Directors”), with vesting provisions as determined by the Board of Directors. Stock-based compensation expense for the years ended December 31, 2022 and 2021 was: RSUs DSUs Stock Options Phantom units Year Ended December 31, 2022 2021 507 272 — 779 — $ $ $ 672 212 3 887 26 $ $ $ As of December 31, 2022, unrecognized compensation expense for RSUs was $297, which is expected to be recognized over a weighted average period of 1.2 years. 71 Restricted Share Units The following table summarizes RSU activity: Unvested - December 31, 2020 Granted Cancelled/forfeited Vested, net of shares withheld Unvested - December 31, 2021 Granted Cancelled/forfeited Vested, net of shares withheld Unvested - December 31, 2022 Number of RSUs Weighted Average Grant-Date Fair Value Per RSU 2,467,002 $ 891,000 (413,335) (946,328) 1,998,339 $ 759,000 (395,569) (889,762) 1,472,008 $ 0.42 0.76 0.48 0.46 0.53 0.59 0.51 0.49 0.60 During the years ended December 31, 2022 and 2021, the Company withheld shares equivalent to the value of employee withholding tax obligations which resulted from RSUs vesting in the period. Shares withheld are considered cancelled/forfeited. Under the LTIP, a portion of the RSU awards vest on a fixed future date providing the recipient continues to be affiliated with Vista on that date. Other RSU awards vest subject to achievement of certain performance and market criteria, including the accomplishment of certain corporate objectives and the Company’s share price performance. Of the unvested RSUs, approximately 43% will vest based on fixed future dates, and approximately 57% will vest on share-price criteria. The minimum vesting period for RSUs is one year. Deferred Share Units The DSU Plan provides for granting of DSUs to non-employee directors. DSUs vest immediately; however, the Company will issue one Common Share for each DSU only after the non-employee director ceases to be a director of the Company. In March 2022, the Board of Directors granted 324,000 DSUs and the Company recognized $272 of DSU expense. In February 2021, the Board of Directors granted 204,000 DSUs and the Company recognized $212 of DSU expense. The following table summarizes DSU activity: Number of DSUs 726,000 $ 204,000 930,000 $ 324,000 1,254,000 $ Weighted Average Grant-Date Fair Value per DSU 0.57 1.04 0.68 0.84 0.72 Outstanding - December 31, 2020 Granted Outstanding - December 31, 2021 Granted Outstanding - December 31, 2022 72 Stock Options The following table summarizes option activity: Weighted Average Remaining Weighted Average Outstanding - December 31, 2020 Outstanding - December 31, 2021 Outstanding - December 31, 2022 Number of Options 1,367,000 $ 1,367,000 $ 1,367,000 $ Exercisable - December 31, 2022 1,367,000 $ The following table summarizes unvested option activity: Exercise Price Per Option Contractual Term (Years) 0.71 0.71 0.71 0.71 2.63 1.64 0.64 0.64 $ $ $ $ Aggregate Intrinsic Value 507 38 — — Unvested - December 31, 2020 Vested Unvested - December 31, 2021 Unvested - December 31, 2022 Phantom Units Weighted Average Weighted Average Remaining Grant-Date Amortization Number of Fair Value Options Per Option 33,333 $ (33,333) — $ — $ 0.31 0.31 — — Period (Years) 0.25 — — The value of each phantom unit is equal to the Company’s share price on the vesting date and is payable in cash. Phantom units vest on fixed future dates provided the recipient continues to be affiliated with Vista on those dates. The Company accounts for these units as awards classified as liabilities. The Company recognized $26 of compensation expense for these units in the year ended December 31, 2021. The Company paid $65 for phantom units which vested during the year ended December 31, 2021. A summary of unvested phantom units is set forth in the following table: Unvested - December 31, 2020 Vested Unvested - December 31, 2021 Unvested - December 31, 2022 Weighted Average Common Shares Basic Common Shares Effect of dilutive stock-based awards Diluted Common Shares Weighted Average Remaining Number of Vesting Term Phantom Units (Years) 72,000 (72,000) — — 0.5 — — At December 31, 2022 118,005,490 — 118,005,490 2021 110,263,237 — 110,263,237 Unvested RSUs representing 1,472,008 Common Shares, stock options to purchase 1,367,000 Common Shares, warrants to purchase 7,408,101 Common Shares, and vested DSUs representing 1,254,000 unissued Common Shares were 73 outstanding at December 31, 2022 but were not included in the computation of diluted weighted average Common Shares outstanding because their effect would have been anti-dilutive. 7. Commitments and Contingencies The Mt Todd site was not reclaimed by the predecessor owners when the mine closed in 2000. Reclamation obligations associated with this period and prior to Vista’s acquisition in 2006 are presently the responsibility of the Northern Territory, Australia Government (the “NT Government”). At such time as we provide notice to the NT Government that we intend to proceed with development, the Company will then assume these historical rehabilitation liabilities currently stated by the NT Government at A$73 million. Under an agreement with the Jawoyn Association Aboriginal Corporation with respect to Mt Todd, we have agreed to a gross proceeds royalty (“GPR”) ranging between 0.125% and 2.0%, depending on prevailing gold prices and foreign exchange rates, and a 1.0% GPR not tied to gold price or foreign exchange rates. The combined GPR range is 1.125% to 3.0%. Our exploration and development activities are subject to various laws and regulations governing the protection of the environment. These laws and regulations are continually changing and are generally becoming more restrictive. Future expenditures that may be required for compliance with these laws and regulations cannot be predicted. If the Company determines that it is probable that an obligation exists and the amount can be reasonably estimated, a provision for environmental liability would be recorded. This may include reclamation costs attributable to mining claims previously held by the Company should no other responsible or potentially responsible parties be identified. We conduct our operations in a manner designed to minimize effects on the environment and believe our operations comply with applicable laws and regulations in all material respects. During 2022, the Company reviewed the provision for environmental liability for a previously held non-core property and the associated contingent liability and determined that the reclamation costs were neither probable nor could be reasonably estimated. The Company reversed its provision for environmental liability, which resulted in a $240 gain in other income/(loss). 8. Supplemental Cash Flow Information and Material Non-Cash Transactions As of December 31, 2022 and 2021, all our cash was held in liquid bank deposits and/or government instruments in the United States or Australia. There were no significant non-cash transactions for the years ended December 31, 2022 and 2021. 9.

The valuation allowances of $62,167 and $63,227 at December 31, 2022 and 2021, respectively, related mainly to operating loss carryforwards where utilization is not more likely than not. The Company periodically assesses both positive and negative evidence to determine whether it is more likely than not that deferred tax assets can be realized prior to expiration. Loss Carryforwards The Company’s tax loss carryforwards expire as follows: 2023 2024 2025 2026 2027 2028 2029 2030 2031 2032 2033 2034 2035 2036 2037 2038 2039 2040 2041 2042 Noncapital Canada U.S. Mexico Barbados Total — — — 1,027 847 5,245 4,022 5,032 3,806 6,397 6,185 4,420 3,729 2,799 1,916 2,666 3,338 2,829 3,195 704 58,157 $ — — — — — — — 1,748 3,407 2,323 3,098 — 2 2,655 2,482 — — — — — 15,715 $ 392 — 84 863 — — — — 75 52 — — — — — — — — — — 1,466 $ 6 6 6 5 7 7 2 — — — — — — — — — — — — — 39 $ 398 6 90 1,895 854 5,252 4,024 6,780 7,288 8,772 9,283 4,420 3,731 5,454 4,398 2,666 3,338 2,829 3,195 704 75,377 $ U.S. loss carryforwards for tax years beginning in 2018 through 2022 of $2,401, Canadian capital loss carryforwards of $106,623 and Australian NOLs of $63,810, which do not expire, are not included in the previous table. Accounting for Uncertainty in Taxes Accounting Standards Codification Topic 740 (“ASC 740”) requires the Company to evaluate its income tax positions and recognize a liability for uncertain tax positions that are not more likely than not to be sustained by tax authorities. As of December 31, 2022 and 2021, the Company believes it had no income tax uncertainties that required recognition of a liability. If the Company were to determine that uncertain tax positions meet the criteria of ASC 740, an estimated liability and related interest and penalties would be recognized as income tax expense. Tax Statute of Limitations The Company files income tax returns in Canada, U.S. federal and state jurisdictions, and other foreign jurisdictions. There are currently no tax examinations underway for these jurisdictions. Furthermore, the Company is no longer subject to Canadian tax examinations by the Canadian Revenue Agency for years ended on or before December 31, 2018 or U.S. federal income tax examinations by the Internal Revenue Service for years ended on or before December 31, 2018. Some 76 U.S. state and other foreign jurisdictions are still subject to tax examination for years ended on or before December 31, 2017. Although certain tax years are closed under the statute of limitations, tax authorities can still adjust losses being carried forward to open years. 10. Geographic and Segment Information The Company has one reportable operating segment, consisting of evaluation, acquisition, and exploration activities. We evaluate, acquire, explore and advance gold exploration and potential development projects, which may lead to gold production or value adding strategic transactions. These activities are currently focused principally in Australia. We reported no revenues during the years ended December 31, 2022 or 2021. Geographic location of mineral properties and plant and equipment is provided in Notes 4 and 5, respectively. 11.
