Compliance with NI 43-101
As required by National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”), Capstone has
filed technical reports detailing the technical information related to its material mineral properties discussed herein.
For the purposes of NI 43-101, the Company’s material mineral properties are the Pinto Valley Mine, Cozamin Mine,
Minto Mine, and the Santo Domingo Project. Unless otherwise indicated, Capstone has prepared the technical
information in this Annual Information Form (“Technical Information”) based on information contained in the
technical reports, news releases and other public filings (collectively, the “Disclosure Documents”) available under the
Company’s profile on SEDAR at www.sedar.com. Each Disclosure Document was prepared by or under the supervision
of or approved by a Qualified Person as defined in NI 43-101. For readers to fully understand the information in this
Annual Information Form, they should read the Disclosure Documents in their entirety, including all qualifications,
assumptions and exclusions that relate to the Technical Information set out in this Annual Information Form which
qualifies the Technical Information. The Disclosure Documents are each intended to be read as a whole, and sections
should not be read or relied upon out of context. Readers are advised that mineral resources that are not mineral
reserves do not have demonstrated economic viability. The Technical Information is subject to the assumptions and
qualifications contained in the Disclosure Documents.

Classification of Mineral Reserves and Mineral Resources

In this Annual Information Form and as required by NI 43-101, the definitions of proven and probable mineral reserves
and measured, indicated and inferred mineral resources are those used by Canadian Provincial securities regulatory
authorities and conform to the definitions utilized by the Canadian Institute of Mining, Metallurgy and Petroleum
(“CIM”) in the “CIM Standards on Mineral Resources and Reserves – Definitions and Guidelines” adopted on
August 20, 2000 and amended December 11, 2005 and November 27, 2010 (“CIM Standards”).

Cautionary Note to US Investors Concerning Estimates of Mineral Reserves and Mineral Resources

The disclosure in this Annual Information Form uses mineral resource and mineral reserve classification terms that
comply with reporting standards in Canada, and, unless otherwise indicated, all mineral resource and mineral reserve
estimates included in this Annual Information Form have been prepared in accordance with NI 43-101. NI 43-101 is a
rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer
makes of scientific and technical information concerning mineral projects. These standards differ significantly from
the disclosure requirements of the SEC set forth in Industry Guide 7. Consequently, mineral resource and mineral
reserve information contained in this Annual Information Form is not comparable to similar information that would
generally be disclosed by US companies in accordance with the rules of the SEC.

In particular, the SEC’s Industry Guide 7 applies different standards in order to classify mineralization as a reserve. As
a result, the definitions of proven and probable reserves used in NI 43-101 differ from the definitions in Industry
Guide 7. Under SEC standards, mineralization may not be classified as a “reserve” unless the determination has been
made that the mineralization could be economically and legally produced or extracted at the time the reserve
determination is made. Accordingly, mineral reserve estimates contained in this Annual Information Form may not
qualify as “reserves” under SEC standards.

In addition, this Annual Information Form uses the terms “measured mineral resources”, “indicated mineral
resources” and “inferred mineral resources” to comply with the reporting standards in Canada. The SEC’s Industry
Guide 7 does not recognize mineral resources and US companies are generally not permitted to disclose resources in
documents they file with the SEC. Investors are cautioned not to assume that any part or all of the mineral deposits in
these categories will ever be converted into SEC defined mineral “reserves.” Further, “inferred mineral resources”
have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically.
Therefore, investors are also cautioned not to assume that all or any part of an inferred mineral resource exists. In
accordance with Canadian rules, estimates of “inferred mineral resources” cannot form the basis of feasibility or other
economic studies, except in rare cases. In addition, disclosure of “contained ounces” in a mineral resource estimate is
permitted disclosure under NI 43-101 provided that the grade or quality and the quantity of each category is stated;
however, the SEC normally only permits issuers to report mineralization that does not constitute “reserves” by SEC
standards as in place tonnage and grade without reference to unit measures. For the above reasons, information
contained in this Annual Information Form containing descriptions of our mineral resource and mineral reserve
estimates is not comparable to similar information made public by US companies subject to the reporting and
disclosure requirements of the SEC.

Three Year History

Financial Year Ended December 31, 2011

On March 14, 2011, Capstone reported the results of a pre-feasibility study for the Phase V expansion at the
Minto Mine which included underground mineral reserves associated with the Minto East, Area 2 and 118 ore
deposits.

On May 30, 2011, the Company announced the results of a NI 43-101 compliant mineral resource estimate for the
Wildfire/Copper Keel area at the Minto Mine.

On June 20, 2011, the Company announced the results of an initial mineral resource estimate for the Mala Noche
Footwall Zone at the Cozamin Mine.

On August 15, 2011, the Company announced the results of the pre-feasibility study on the Santo Domingo Project.

Acquisition of Far West

On April 17, 2011 the Company and Far West announced that they had entered into a definitive agreement pursuant
to which a wholly-owned subsidiary of the Company agreed to acquire all of the issued and outstanding common
shares of Far West, by way of a court-approved plan of arrangement.

Far West shareholders were entitled to elect to receive, in exchange for each Far West share held either (i) 1.825
shares of Capstone and C$1.00 in cash, (ii) 2.047 shares of Capstone and C$0.001 in cash, or (iii) C$9.19 cash, subject
to proration on the basis of an aggregate maximum cash amount of approximately up to C$79.0M and provided that
no Far West shareholder that elected option (iii) above, would receive less than C$1.00 in cash per Far West share.
Far West received, at the meeting of its security holders held on June 13, 2011, security holder approval for the
arrangement and on June 17, 2011 Capstone completed its acquisition of Far West.

As part of the acquisition, Capstone issued 12,091,629 options in exchange for 5,907,000 options of Far West, which
equates to an exchange ratio of 2.047 Capstone options for every Far West option exchanged. Those options issued
by Capstone were on the same terms and conditions as those exchanged by the Far West holders. As a result of these
exchanges, Capstone recorded the fair value of the vested options of $19.3M as a cost of the transaction. In addition,
Capstone issued 4,451,221 warrants in exchange for 2,439,025 warrants of Far West which equates to an exchange
ratio of 1.825 Capstone warrants for every Far West warrant exchanged. Those warrants issued by Capstone were on
the same terms and conditions as those exchanged by the Far West holders, except for the exercise price, which was
reduced by C$1.00. As a result of these exchanges, Capstone recorded the fair value of the vested warrants of $4.0M
as a cost of the transaction.

The Company filed a Form 51-102F4 Business Acquisition Report on July 7, 2011 in respect of its acquisition of
Far West.

KORES Strategic Partnership

Concurrent with the acquisition of Far West, the Company announced that it entered into a strategic partnership with
KORES. Under the terms of the partnership, Capstone sold to KORES a 30% indirect interest in Far West for cash
consideration of $194.2M. As a result of this partial disposition of its ownership interest in Far West, Capstone
recorded a $44.9M reduction to the carrying value of the Far West mineral properties on the date of purchase. This

ITEM 3 - DESCRIPTION OF THE BUSINESS

3.1

General

Capstone’s strategic goal is to be the best managed copper company within our peer group, delivering industry
leading returns. Capstone is focused on profitability, a growing production profile and operating in a safe and
responsible manner. Our well defined growth strategy has two tiers. The first is organic growth of our existing
development projects and extension of our existing mines. The second is through the acquisition of producing
properties. Both are focused on copper and in politically safe and mining friendly jurisdictions in the Americas.
Capstone’s material mineral properties consist of:







the Pinto Valley Mine, an open pit copper-molybdenum mine located in Arizona, US;
the Cozamin Mine, a copper-silver-zinc-lead underground mine located in the State of Zacatecas, Mexico;
the Minto Mine, an open pit and underground copper-gold-silver mine located in the Whitehorse Mining
District, Yukon, Canada; and
the Santo Domingo Project, a large scale copper/gold/magnetite project in Chile, in which Capstone holds a
70% interest through a long-term strategic partnership with KORES.

- 11 -

In addition to ongoing exploration at the Cozamin Mine aimed at increasing mine life and throughput, Capstone has a
portfolio of early stage base metals exploration projects that have the potential to add to production over the longer
term. This exploration is focused in mining friendly jurisdictions, with preference given to areas where a team is in
place and the permitting process is well understood. The two primary exploration projects the Company is pursuing at
the present time are:



Capstone entered into an earn-in and joint venture agreement with Westminster Resources Ltd. on April 17,
2012 for the Cumbral Property located in Sonora, Mexico and may earn a 70% interest in the property. This
property was assigned to a 100% owned exploration subsidiary of the Company, Capstone Exploraciones, S.A.
de C.V., and is being actively explored.
Capstone entered into an option agreement with SQM to earn up to 70% of Project Providencia in Region II,
Chile, which is a very large under-explored land package in the world’s most prolific copper jurisdiction. The
initial option is on 350,000 hectares and would be reduced over time to a maximum of 50,000 hectares if a
joint venture is formed. Capstone is the operator of the project and may earn up to a 70% interest in the
Property with the right to withdraw from the project at any time.

Capstone is actively pursuing additional exploration opportunities through earn-in and joint venture models.

Precious Metals Streams

During 2008, the Company sold all of its gold and silver production from the Minto Mine over the life of mine to Silver
Wheaton Corp. (“Silver Wheaton”) in consideration for an upfront payment of $37.5M and a further payment of the
lesser of $300 per ounce of gold and $3.90 per ounce of silver (subject to a 1% inflationary adjustment after three
years and each year thereafter) and the prevailing market price for each ounce delivered. If production from the
Minto Mine exceeds 30,000 ounces of gold per year, Silver Wheaton will be entitled to purchase only 50% of the
amount in excess of that threshold. The Company has recorded the proceeds received as deferred revenue and will
recognize this amount as an adjustment to revenue as the appropriate ounces are delivered.

Under its April 2007 agreement with Silver Wheaton the Company has a commitment to sell the Cozamin Mine’s silver
production over a 10 year period to Silver Wheaton. Under the terms of the arrangement, Silver Wheaton agreed to
pay for each ounce of refined silver from the mine the lesser of $4.00 per ounce of silver (subject to a 1% inflationary
adjustment after three years and each year thereafter) and the prevailing market price for each ounce of silver,
subject to price adjustments. Further, the Company agreed to deliver a minimum of 10.0 million ounces of silver to
Silver Wheaton over a ten year period. If, at the end of ten years, the Company has not delivered the agreed upon 10
million ounces of silver, then it has agreed to pay Silver Wheaton $1.00 per ounce of silver not delivered. To
December 31, 2013 a total of 8.9 million ounces had been delivered against the contract since its inception.

Competitive Conditions

The mining industry is intensely competitive, particularly in the acquisition of additional mineral reserves and
resources in all of its phases of operation and the Company competes with many companies possessing similar or
greater financial and technical resources.

The Company’s competitive position is largely determined by its costs compared to other producers throughout the
world and its ability to maintain its financial integrity through metal price cycles. Costs are governed to a large extent
by the location, grade and nature of the Company’s mineral reserves as well as by operating and management skills.
In contrast with diversified mining companies, the Company focuses on copper production, development and
exploration, and is therefore subject to unique competitive advantages and disadvantages related to the price of
copper and to a lesser extent, the price of base metal by-products. If copper prices substantially increase, the
Company will be in a relatively stronger competitive position than diversified mining companies that produce, develop
and explore for other minerals in addition to copper. Conversely, if copper prices substantially decrease, the Company
will be at a competitive disadvantage to diversified mining companies.

- 14 -

Environmental Protection

The Company’s operations (Pinto Valley, Cozamin and Minto) and development project (Santo Domingo) are in the US,
Mexico, Canada and Chile and are subject to national and local laws and regulation in respect of the construction,
operating standards and the eventual abandonment and restoration costs for the site. Since the Cozamin Mine, and
certain areas of the Minto Mine are relatively small tonnage and higher grade operations, the overall financial impact
of the environmental protection requirements is minor relative to the overall financial performance of the Company.
Each operation is subject to an asset retirement obligation review at year end, which assesses the abandonment and
restoration cost for the operation at that point, and any changes are reflected in the balance sheet and could flow
through the earnings statement. While the financial obligations will increase as disturbance increases, given the
relatively modest amounts involved, such impacts are likely to be relatively minor from a capital and earnings
perspective, in the near term. Pinto Valley Mine, has a long history of operations in an established mining district of
Arizona. As a low-grade, high tonnage operation the reclamation issues, while different from those at Capstone’s
other operations, were reviewed with regulators in 2013 and detailed local guidance and regulations around
acceptable closure practices are well understood. In addition, the site has undergone significant progressive
reclamation. The Santo Domingo project is currently unpermitted; the environmental protection requirements could
affect the project’s advancement by delaying or preventing approvals consistent with the economic development of
the project. Chile has a well-defined permitting process and clear environmental protection objectives and timely
approval is expected for a project of the scope of Santo Domingo in its environmental setting.

Overall, the Company’s assets are in mature and stable mining jurisdictions and the environmental protection
requirements are not anticipated to be a significant impediment to Capstone carrying out its business, nor should they
result in an unsustainable burden on the Company’s earnings.

Employees

As of December 31, 2013, the Company had approximately 1,307 employees and approximately 626 contractors.

The Company’s workforce is not unionized with the exception of approximately 354 hourly employees at the Pinto
Valley Mine which are members of six unions, governed by one collective bargaining agreement negotiated by the
United Steelworkers Union.

Foreign Operations

Three of the Company’s material properties are located in foreign jurisdictions, being the Pinto Valley Mine located in
the United States, Cozamin Mine located in Mexico and the Santo Domingo Project located in Chile.

Social and Environmental Policies

The Company places great emphasis on providing a safe and secure working environment for all of Capstone’s
employees and contractors, and recognizes the importance of operating in a sustainable manner. There were no fatal
or long-term disability accidents or significant environmental incidents at any of Capstone’s operations through the
financial year ended December 31, 2013. The Company-wide lost time incident frequency rate (including contractors)
was reduced from 1.15 in 2012 to 0.35 in 2013. Capstone’s Environmental, Health, Safety & Sustainability Committee
meets at least four times annually to review the Company’s performance and compliance as related to such matters.
Capstone has adopted an Environmental, Health, Safety and Sustainability Policy, and has communicated the
importance of working in a safe and secure working environment to all employees and significant contractors at all
sites.

3.3

Pinto Valley

The Pinto Valley Mine is the subject of a report titled “Pinto Valley Property Mineral Resource Estimate, NI 43-101
Technical Report” dated December 11, 2013 (the “Pinto Valley Report”). This technical report was compiled by
Kirkham Geosystems Ltd. and written by Garth Kirkham, P. Geo., a Qualified Person as defined in NI 43-101. The
description of the Pinto Valley Mine in this document is based on assumptions, qualifications and procedures which
are set out only in the full Pinto Valley Report. Reference should be made to the full text of this report, which is
available in its entirety on SEDAR at www.sedar.com under the Company’s profile.

Project Description and Location

The Pinto Valley poly-metallic base metal mine is located in the Globe-Miami district in Gila County, Arizona
approximately 80 miles east of Phoenix in the southern United States. The Pinto Valley Mine and Concentrator are at
an elevation of 1,300 m. The core of the Pinto Valley property consists of 69 patented lode mining claims. Also
included in the property are 53 patented mill sites. Adjacent to the patented claims are 329 unpatented lode mining
claims and mill sites. Seven parcels of fee (private) land are associated with the property.

Capstone entered into a purchase agreement with BHP Copper Inc. April 28, 2013 for the Pinto Valley Mine and
associated railroad operations. 100% ownership of the properties by Capstone was acquired as of October 11, 2013
for a cost of $650M USD. A 2% net smelter return (NSR) royalty applies to 26 of the unpatented mining claims which
are not expected to be mined until after 2026.

The Pinto Valley operations require 17 permits granted from various state and federal agencies; operations of the
railroad requires five permits mainly from Arizona State. Permits are in good standing.

Environmental liabilities at the Pinto Valley Mine relate to the heap leach facility, tailings deposits and associated
engineered containment infrastructure, waste rock dumps as well as some water stored at the site that is impacted by
operations as well as the removal of all operational infrastructures. A closure plan has been developed and approved
(most recently in October 2013 as part of the permit transfer process) detailing methods and costs associated with
restoring the site to an acceptable environmental standard. Engineered covers will be placed on tailings and waste
rock such that interactions with surface water are minimized. Very little water will be released from the site during
closure and appropriate diversions will be established to direct any storm water away from impacted areas. Letters of
credit totaling $87.1M have been filed with the Arizona State Mining Inspector (“ASMI”) and the Arizona Department
of Environmental Quality (“ADEQ”) in accordance with the mandate of these agencies and associated regulations and
policies. These financial security amounts represent the estimated reclamation cost for the mining operations at the
end of the 12 year permitted mine plan on an undiscounted basis. These amounts are reviewed when the proponent
alerts the agency to a change in the mine plan or closure measures.

Pinto Valley Mine has all of the necessary permits to conduct mining activities for the next twelve years, with the
exception of an approved Plan of Operations that is currently under review by the U.S. Forest Service (USFS). The Plan
of Operations is a compilation of several special use permits and other authorizations to use USFS lands adjacent to
the private lands where mining activities occur. This Plan is subject to a National Environmental Policy Act review that
was initiated under BHP and is continuing with Pinto Valley Mining Corp. as the proponent. Once approved, it is
expected that an additional financial assurance will be required by the USFS, likely in 2015. As at December 31, 2013,
the Company was approximately 50% through the process with no material risks identified. The Company’s
assessment is that any modifications to the Plan of Operations following this review would not likely result in any
material change to permitted operating parameters or financial obligations under any applicable permits. The major
instruments or authorizations permitting and governing operations for the project include an Aquifer Protection
Permit from ADEQ, a Mined Land Reclamation Plan approved by ASMI and an approved Plan of Operations (“USFS”).

Accessibility, Climate, Local Resources, Infrastructure and Physiography

The Pinto Valley Mine is located 13 km (8 miles) west of Miami, a town of approximately 1,800 residents, and 21 km
(13 miles) west of Globe, the County seat, with approximately 7,500 residents. Because of a long-standing mining
tradition in the area, local services are already in place to supply the mine's needs. The current level of community
services is deemed to be adequate for the needs of the mine. Medical facilities are available at the Cobre Valley
Community Hospital located in Miami. Fire, police, public works, transportation, and recreational facilities are in place
and fully functioning. The community has an adequate supply of permanent housing and temporary housing to
accommodate the Pinto Valley Mine's current workforce.

Infrastructure for Pinto Valley includes the existing maintenance shops, administration offices, environmental
facilities, water and electric distribution systems, and other miscellaneous facilities. Off-site infrastructure includes
the incoming electric power generation and transmission capacity provided by the Salt River Project (SRP), the local
highway system provided by state and federal governments, the local transportation services provided by various
contractors, and the telephone and data communications systems. Tailings are deposited in existing permitted tailings
storage facilities using the same practices from previous operations. The majority of the tailings are placed in Tailings
Dam No. 4; Tailings Dam No. 3 is used for tailings placement during maintenance activities at Tailings Dam No. 4.
There is an adequate source of water with potable water coming from 4 groundwater wells and service water from a
Peak Well system.

A large network of roads has been built to serve the Pinto Valley Mine. The primary access, FR 287, is a paved road; all
other roads are unpaved. Some roads are well-maintained to accommodate daily traffic, whereas others are not
maintained and require four-wheel drive vehicles. Although FR 287 is a public road that passes through the mine
property, public access to the mine facilities is restricted and managed by gates and Pinto Valley Mine security
personnel.

The climate is the region is semi-arid with an average annual precipitation in the region of 58.4 cm and falls occurring
in a bimodal pattern. Most of the rainfall occurs during the winter and summer months, with dry periods in the spring
and fall. The average annual maximum temperature is 25°C. July is the warmest month with an average maximum
temperature of 36°C. The average annual minimum temperature for the coolest month is 1°C in January.

The Pinto Valley Mine is located in east-central Arizona in the structural transition zone between the Sonoran section
of the Basin and Range physiographic province to the south-southwest, and the Colorado Plateau to the north. The
terrain surrounding the mine property is generally mountainous, dominated by sharp landforms and prolific exposures
of the variety of bedrock formations present in the region. The Pinto Valley Mine is entirely within the Pinto Creek
watershed, where local elevations range from about 1,067 m to 1,524 m above mean sea level.

The Pinto Valley Mine is near the boundary of areas mapped as the Interior Chaparral biotic community and the
Arizona Upland subdivision of Sonoran desert scrub biotic community. Most of the plant and animal species observed
have wide environmental tolerances from being on the eco tone of two major plant communities.

History

The Globe-Miami district is one of the oldest and most productive mining districts in the United States. The first
recorded production from the district was in 1878. Since that time, over 15 billion pounds of copper have been
produced.

Pinto Valley Mining Division originated as Miami Copper Company in 1909. In 1960, the Tennessee Corporation took
over Miami Copper Company, and, in 1969, Cities Service Company merged with the Tennessee Corporation. In late
1982, Occidental Petroleum Corporation (Occidental) acquired Cities Service Company. In February 1983, Occidental
sold the Miami operations to Newmont Mining Corporation. At this time, the company's name was changed to Pinto
Valley Copper Corporation (Pinto Valley Copper). In November 1986, Newmont merged the Pinto Valley Copper
assets into Magma Copper Company holdings, and Pinto Valley Copper became the Pinto Valley Mining Division of
Magma Copper Company. In December 1995, Broken Hill Proprietary Company Limited (BHP) purchased Magma
Copper Company. With the merger of BHP and Billiton in 2001, the Pinto Valley Mining Division became the Pinto
Valley Operations of BHP Copper Inc.

- 17 -

Development of the Pinto Valley open pit began in 1972, and the mine and concentrator went into production in
1974. Previously, a chalcocite-enriched zone of the deposit was mined from 1943 until 1953, as the Castle Dome
Mine. Sulphide ore from the Pinto Valley open pit operation was processed at the unit's concentrator, which
produced a copper concentrate containing approximately 28% copper and a molybdenum disulphide by-product. The
copper concentrate was then trucked to a smelter and refinery in San Manuel, Arizona. In February 1998, sulphide
mining and milling was suspended due to depressed copper prices. The concentrator was placed under care and
maintenance and the mining equipment fleet was sold. Operating and environmental permits were maintained during
the suspension of sulphide operations, as were the water and electrical systems, although these were maintained at
lower usage rates than during mining and milling operations. Cathode copper production continued during the
suspension of sulphide operations at the Pinto Valley and Miami SX-EW facilities.

In April 2006, a study was completed to determine the feasibility of rehabilitating the mill and flotation plant and
restart mining activities. A provisional approval for restart was granted in December 2006 and final approval was
granted in early 2007. The resource and reserve estimates made in 1996 were reviewed and validated, and these
estimates were restated in June 2007. The Pinto Valley Mine operated for 18 months before depressed copper prices
forced it to be placed under care and maintenance again. The notice and cessation of the operation occurred on
January 20, 2009.

In 2011, a new study was commissioned to restart the mine; it was peer reviewed and approved by BHP Copper Inc. in
January 2012 and the mill was restarted in December 2012.

The declared resource and reserve statement (JORC compliant) for Pinto Valley by BHP Copper Inc. was published in
“BHP Annual Report 2013”. Capstone has not completed the work necessary to verify the classification of the
resource and reserve statement. Capstone is not treating the resource and reserve statement as NI 43-101 defined
mineral resources and mineral reserves verified by a Qualified Person. The historical estimates should not be relied
upon. The Pinto Valley Operation will require considerable further evaluation which Capstone’s management and
consultants intend to carry out in due course. Capstone does not have a copy of the report that includes the resource
and reserve statement signed by a professional geologist. Therefore, Capstone cannot verify the resource or reserves
or comment on whether the estimate was made in compliance with the current standards. Capstone is not relying on
these estimates.

Geological Setting

The Globe-Miami mining district of central Arizona covers porphyry copper deposits (Creasey, 1980) associated with
Paleocene (59 to 63 Ma) Granodiorite to Granite Porphyry stocks. The porphyry copper deposits have been
dismembered by faults and affected by later erosion and minor oxidation. Vein deposits and possible exotic copper
deposits are also found within the district.

The Globe-Miami district contains igneous, metamorphic, and sedimentary rocks of Precambrian, Paleozoic, Tertiary,
and Quaternary age. The hydrothermal ore deposits in the district comprise vein deposits and typical porphyry copper
deposits. The primary minerals of the porphyry copper deposits are chiefly pyrite and chalcopyrite with minor
amounts of molybdenite; gold and silver are recovered as by-products.

The host rock for the porphyry copper deposit is Precambrian age Lost Gulch Quartz Monzonite.

The deposit is bound by post-mineral faults. The South Hill fault is on the south side, the Jewel Hill fault is on the east
side, and the Gold Gulch fault is on the west side. Minor post mineral normal displacement has taken place on the
Dome fault, a pre-mineral structure that strikes north-easterly across the north limb of the deposit.

Diabase forms thin dikes in pit exposures. These dikes commonly contain higher copper content than surrounding
Quartz Monzonite. In the eastern part of the deposit, a Diabase sill lies at the top of the ore. Diabase west of the Gold
Gulch fault is mineralized by pyrite and chalcopyrite veins with abundant magnetite near mineralized Granite
Porphyry.

Mapping the regional Pinto Valley tenement has identified a number of new mineral occurrences. Copper
mineralization was observed at a number of contacts between two genetically different granitic bodies. Surface

exposure of porphyry breccia systems were also found bearing pyrite and chalcopyrite in a jarosite-dominated oxide
precipitate. These sites were analyzed with field portable TerraSpec which detected dickite, indicating hydrothermal
alteration. A number of massive magnetite/hematite seams bearing manganese, pyrite, and copper were mapped in
skarn contacts around the fringe of limestone bodies. A skarn occurrence was found in contact with an intrusive
Diabase unit bearing a stockwork of sulphide-rich "D" veins. Also a number of old workings were found throughout
the area, testing a range of copper-bearing geological settings, such as porphyry stock, pegmatitic intrusive,
mineralized skarn, intrusive contact, and oxide occurrence under tertiary cover.

Exploration

Surface mapping has been the main source of additional data throughout the identification phase for Pinto Valley 2
(PV2). Two campaigns were conducted on separate occasions to improve both the geotechnical and geometallurgical
knowledge of the deposit. All work stated in this section was performed by or on behalf of BHP Copper. The surface
mapping for geotechnical information focused primarily on the bedding planes, major structures, and overall
geological strength index. Various ore-types were confirmed using surface mapping and by reviewing core logs.
Alteration zones and ore-types were identified in the pit wall and correlated against core samples taken in previous
drill campaigns.

Descriptions from the core logs were used to plot the correlation between rock type and alteration zone. The primary
ore-types were narrowed down to Ruin Granite, Quartz Monzonite, and Diabase. These ore-types are based on
relative abundance, gangue mineralogy, copper grade, alteration, and the potential impact on overall production
(recovery, throughput, and consumption of reagents/energy).

During the brownfield surface mapping campaign in the Pinto Valley district a number of new copper mineralization
occurrences were identified. Three principle target zones are presented below:

•

Kozi Prospect

o Mapped over the Ruin Granite, southeast of the pit
o Reflected-light thin section of the rock shows a brecciated texture evidence of hydrothermal

alteration, relict sulphide boxwork, and some pyrite grains

o Chemical assay reports for samples taken from this area indicate > 1% Cu

• Bondi Prospect

o Related to the Dripping Spring Quartzite, and some zone with hornfels of biotite-magnetite outcrop

as a 90-metre high cliff face and narrow gully incised by active creek systems

o Near the tails facility
o Area warrants further review to identify the source of copper oxide precipitate
o Difficult to state the copper sources due to the oxidation observed in the quarzites
o The state is structurally complex and partially covered by post-mineral cover

• Mati Prospect

o Mapped limestone sequences 250 m northeast of the pit
o Copper sulphides related to magnetite replacement suggest a tertiary intrusion origin
o

Skarnification zone with prograde stage development of pyroxene and wollastonite and retrograde
stage of epidote

Two other small zones containing copper oxide were identified; one is an old copper mine near the Carlotta mine
cross road in the southwest boundary of Pinto Valley, the other is an outcrop of Apache Leap Tuff related to a small
paleochannel in an active creek.

The Company will be assessing the results of this historical exploration activity and the potential impact on the
development of the mining operations and future exploration efforts.

Mineralization

The hydrothermal ore deposits in the district comprise vein deposits and typical porphyry copper deposits. On the
basis of predominant metals, the vein deposits can be further divided into copper veins, zinc-lead veins, zinc-lead-
vanadium-molybdenum veins, manganese-zinc-lead-silver veins, gold-silver veins, and molybdenum veins (Peterson,
1962). The primary minerals of the porphyry copper deposits are chiefly pyrite and chalcopyrite with minor amounts
of molybdenite; gold and silver are recovered as by-products. Sphalerite and galena occur locally in very small
amounts. Silicate alteration associated with the deposits includes potassic, argillic, sericitic, and propylitic alterations.

The Pinto Valley is a hypogene orebody with chalcopyrite, pyrite, and minor molybdenite as the only significant
primary sulphide minerals. It is the underlying protore of the chalcocite-enriched Castle Dome deposit exhausted in
1953 (Peterson et al., 1951).

Primary sulphide ore minerals consist of pyrite, chalcopyrite, and minor molybdenite that occur in veins and
microfractures, and less abundantly as disseminated grains predominantly in biotite sites. The ore zone grades
outward into a pyritic zone with higher total sulphide content and the ore zone grades inward toward the low-grade
core which has lower total sulphides. Molybdenum distribution generally reflects copper distribution, with higher
molybdenum values usually found in the higher-grade copper zones.

Sulphide deposition at Pinto Valley is controlled to some extent by the host rock. For the most part, the host is Lost
Gulch Quartz Monzonite and Porphyritic Quartz Monzonite, which are similarly altered and mineralized. The sulphide
content decreases in Precambrian Aplite intrusions. Aplite usually contains less than 0.25% copper, whereas adjacent
Quartz Monzonite may have as much as 0.6% copper. The deficiency of copper in Aplite is probably due to the
absence of biotite, which makes up about 7% of Quartz Monzonite. Disseminated chalcopyrite shows an affinity for
biotite, where it is seen to be disseminated through the biotite or partially replacing it. Additional chalcopyrite is also
present in veins which cut both rock types.

The shell has the appearance of a hook in plan view and mimics the pit outline. Rock located south of the ore has
decreasing sulphide content and numerous barren quartz veins. This area has been interpreted as a low-grade core,
and this low-grade zone corresponds spatially with the Granite Porphyry, which is seen as a poor lithologic host for
ore-grade mineralization elsewhere in the deposit. Rock located north of ore has progressively more abundant, late-
stage quartz-pyrite-sericite veins.

Drilling

The pre-2006 Pinto Valley drilling programs comprised a combination of core, rotary, and churn drill holes. Drilling
documentation was limited to BHP Copper internal reports, and there were no listings for vintage data, methods used,
or pre-2010 drilling procedures, other than those found in the internal reports. Churn holes defined much of the early
Castle Dome reserve, which has been mined out. Post-Castle Dome holes were drilled on an original spacing of 400 ft
east-west and 200 ft north-south. Later, drilling was done to infill the original grid to 200 ft spacing in some areas.
Drilling that has occurred since the 1986 block model was constructed includes 10 core holes and 3 reverse circulation
rotary holes drilled in 1992. From the beginning of 1996 to April 1997, 67 reverse circulation exploration and infill
holes were drilled: 48 RC holes (AD and NR-Series totalling 29,665 ft) drilled in 1996, and 19 RC holes (WW and 97-
Series totalling 8,520 ft) drilled during 1997. The WW and 97-Series were drilled in the interior pit and through the
Gold Gulch and Continental faults. Seven of the exploration holes were drilled east of the existing pit and laid the
ground work for future plans of an east pit expansion, known as the Satellite Pit.

- 20 -

The current Pinto Valley drill hole database contains a significant amount of drilling that defined the grades in the
block model that have been mined out, especially as they relate to the Castle Dome mining activity.

All drill hole collar locations were surveyed. The majority of the drill holes are vertical and, therefore, do not have
downhole surveys. However, a majority of the inclined holes do have downhole surveys.

From 2006 through 2008, there have been various drilling campaigns with mixed purpose: delineation, exploration,
geotechnical, and resource classification upgrade drilling. These include 18 G-Series geotechnical holes, 11 HW-Series
holes in 2007, 17 PZ-Series holes drilled in 2008, 17 S-Series holes drilled in 2008, 24 B-Series holes drilled in 2008, and
4 DH-Series holes drilled in 2008.

The most current drilling occurred in 2010 which focused on exploration, and in 2011 and 2012 which focused on infill
drilling for resource classification upgrade in support of restarting operations. Ten holes were drilled in 2010, 40 holes
were drilled in 2011, and 64 holes were drilled in 2012.

Sampling and Analysis

Once drilling is completed, the core is transported to the core handling facility. Here it is placed in wax-covered core
boxes with depth markers for every drill run of up to 10 ft. QuickLogs are done at core reception which includes initial
lithology and a visual estimation of mineralization and alteration, particularly biotite content. The mine is set up on a
bar code system for ease of handling and to track the core and samples. There is a triple bar code tag: the first tag is
for the half core that remains in the box, the second tag is for the split that is sent to the lab for analysis, and the third
tag is for the coarse duplicate and is used to tag the pulps and rejects. The core is logged for geology and split by saw
at one of two stations.

The QuickLog data and the detailed logs are entered into an acQuire® relational database system which also records
the collar, survey, assay, lithology, alteration, mineralization, and geotechnical (RQD) data. This data is tagged and
tracked using the bar codes, and all subsequent assay information provided by the laboratory, including the QA/QC
data, is linked to the database. The system is secured by BHP using protocols and procedures which appear to be
extremely stringent. A dispatch report is created which is then sent to the laboratory and subsequently matched
against the shipments. Deviations and discrepancies are reported and investigated. Any updated assay data from the
laboratory is linked to the bar code system and relayed to the company electronically via Excel® CSV files and
imported into acQuire® automatically. The data is imported into MineSight for the purpose of resource estimation.

A number of different companies and laboratories have provided assay services to Pinto Valley over the years. Details
of sampling and assaying procedures used during the earlier stages of operation are not readily available. Procedures
used by outside labs that ran assays for some of the later drilling campaigns, such as those performed by Mountain
States for the RC holes and Chemex for the AD holes, are also not readily available. The analytical procedures
currently in place at Pinto Valley are in line with industry standards for total copper, but procedures are BHP-specific
with respect to acid soluble copper (i.e., digestion with 10% sulphuric acid, placed in a hot bath at 40 degrees Celsius,
and read after 40 minutes).

Samples were assayed for total copper and acid soluble copper. Composites representing 30-50 ft of the sample
rejects were made and these composites were assayed for total copper, oxide copper, molybdenum, sulphur, and
trace metals of gold and silver. Comparisons were made between the total copper and acid soluble copper assays
from the original assay intervals and the composite intervals.

Independent audits of the Pinto Valley assays were conducted in 1992 and 2000. Results were as follows:

•
•

•

assay values in the Pinto Valley database have been reliably entered;
total copper assays in the Pinto Valley database are reproducible and can be considered representative
within normally-accepted limits of error;
total copper assays in holes below the current pit base can also be considered representative within
normally-accepted limits of error, except in the deeper parts of some RC holes where they may be low-

biased. However, using these assays to estimate grades in the model is acceptable because they will tend to
provide a conservative rather than an overly optimistic estimation of grades;
acid soluble assays in the Pinto Valley database vary considerably depending on the drilling campaign and;
reserves, resources, and production at Pinto Valley are reported as sulphide copper, which is calculated by
subtracting acid soluble copper from total copper. Because biases exist in the acid soluble copper assays, this
procedure generates sulphide copper values that are biased relative to each other as a function of the drilling
campaign. However, sulphide copper values are only slightly lower than overall total copper values, so it can
be reasonably assumed that the sulphide copper values are also globally correct within normally-accepted
limits of error.

As part of the start-up Feasibility Study done in 2006, a QA/QC program was conducted on 101 randomly selected drill
hole assay interval pulp samples and 15 randomly selected core assay intervals. Samples were sent to Skyline
Assayers and Laboratories (Skyline Labs) in Tucson, Arizona to be analysed for total copper and acid soluble copper.
Skyline Labs was instructed to analyse the samples for acid soluble copper using BHP lab procedures. Before the lab
processed these samples, BHP provided instructions for the pulp sample analytical procedures and also provided a
sequential pulp sample list. Included in this QA/QC program for the Feasibility Study were seven sets of a known
National Institute of Standards and Technology (NIST) standard pulps: Copper Ore Mill Heads standard at 0.84% Total
Copper, and a Copper Mill Tails standard at 0.091% Total Copper. These known standard sets were inserted in
sequential order for analysis preceding the 15th pulp sample in the analytical run. All relative precisions are discussed
at a 95% confidence level (estimated using the Student’s T-distribution).

The author of the Pinto Valley Report, Garth Kirkham, visited the property on May 14, 2013. While there he inspected
the core logging facilities, offices, outcrops, historic drill collars, core stage facilities, core receiving area, core sawing
stations, and a tour of the major centres and surrounding towns that are affected by the mining operation. His overall
impression was that of a clean, well-organized and professional environment.

The author randomly selected four complete drill holes from the database and laid the core out at the core storage
area. Site staff supplied the logs and assay sheets so the author could verify the core and logged intervals. The data
correlated with the physical core and no issues were identified. In addition, the author toured the complete core
storage facility, pulling and reviewing core throughout the tour. No issues were identified and recoveries appeared to
be very good to excellent.

The author is confident that the data and results are valid based on the site visit and inspection of all aspects of the
project; this confidence extends to the methods and procedures used. It is the opinion of the independent author
that all work, procedures, and results have adhered to best practices and industry standards required by NI 43-101.
The author also visited Skyline Labs and deemed the labs operations as very professional as is expected from a widely-
used North American laboratory facility.

Mineral Resource and Mineral Reserve Estimates

The mineral resource estimate for Pinto Valley mineralization was completed by
independent consultant
Garth Kirkham, P.Geo., of Kirkham Geosystems using accepted industry standards that conform to NI 43-101
requirements. The mineral resource estimation was completed as of February 28, 2013 and restated based on open
pit production conducted through December 31, 2013.

The mineral resource estimate for Pinto Valley uses a 0.25% copper cut-off grade. The cut-off grade is considered
appropriate given the type of deposit and mining method employed at the mine site.

The Pinto Valley Mine has no declared mineral reserve estimates as defined in the CIM “Estimation of Mineral
Resource and Mineral Reserves Best Practices” guidelines. All previous mineral reserve estimates for Pinto Valley are
considered to be historical in nature. Capstone intends to complete an independent NI 43-101 technical report in 2014
that will include mineral reserves as defined in the CIM “Estimation of Mineral Resource and Mineral Reserves Best
Practices” guidelines.

Reconciliation

Reconciliation was conducted to determine the accuracy of the block model when compared to the mine reported
production. Surveys were utilized to determine the volume of material mined from the block model and these
tonnages were further reconciled with mine production results. The surveys were taken on October 11, 2013 and
December 31, 2013 to reflect the time period that Capstone has owned Pinto Valley Mine. The results indicate there
were nominal variances between the mine reported and block model reconciliation. Reconciliation was also
conducted between the mine and mill reported production. The results indicate nominal variance in that review.

Mining Operations

Capstone Mining Corp. acquired the Pinto Valley copper mine from BHP Copper Inc., a subsidiary of BHP Billiton Ltd.
on October 11, 2013. The restart of the Pinto Valley Mine, which commenced in December 2012, is continuing with a
targeted mill rate of 50,800 tonnes per day and annualized production of 130 million to 150 million pounds of copper
per year.

Operations at Pinto Valley are established; processing facilities, shops, fuel bays, and other support functions are all
operational. Ramping-up capacities while further stabilizing these operations are both critical measures for the
success of the mining operation. The main risks to the mine plan are related to pit slope stability, and these will be
mitigated through ongoing and active observations with ground and radar monitoring applications. The mine
configuration, infrastructure, and site logistics required to mine the exposed ore in the pit are the same as they were
under previous operations.

The mining is executed as an owner/operator operation with a truck/loader fleet. The overall dimensions of the mine’s
mineral deposit, including already extracted ore, measures 7,500×3,500×1,600 ft (~2,300×1,050×500 m), elongating in
an east-northeast direction. The ore body outcrops at the bottom of the current mine surface.

The strip ratio (waste: ore) in 2013 was very low at 0.002:1 as mining operations focused on mining the bottom of the
pit. An average tonnage factor (dry basis) of 2.5 tonnes per cubic metre is used for planning and reporting purposes,
established through reconciliation of plant feed and confirmed by wet and dry weight analysis of whole core. The mill
ore cut-off is variable, nominally set at 0.25% TCu. Stockpile (leach) material-grade cut-off ranges from 0.10% to
0.20% TCu. Material between 0.20% and 0.25% will be stockpiled for future processing.

- 23 -

The Pinto Valley Mine’s applicable taxes include the following:

•

Corporate Taxes – the combined US Federal and Arizona state corporate income tax is calculated at a blended
39.53% rate applied on taxable income. The Alternative Minimum Tax (“AMT”) is calculated at a 20% rate
applied on an adjusted amount of taxable income. A taxpayer pays the higher amount of regular Federal
income tax and the AMT. If AMT is paid, it may generally be used as a credit against regular tax in future
years to the extent regular tax is greater than AMT.

The Arizona state severance tax on metalliferous minerals is charged at a 2.5% rate on 50% of the difference
between the gross value of production and production costs.

• Gila County property taxes are administered by the Arizona Department of Revenue.

Cozamin Mine (Mexico)

The Cozamin Mine is the subject of a report titled “Technical Report, Cozamin Mine, Zacatecas, Mexico” dated
March 31, 2009 (the “Cozamin Report”). This technical report was compiled by SRK Consulting (Canada) Inc. and
written by Robert Sim, P.Geo., Jenna Hardy, P.Geo., Jeff Woods, CP and Gordon Doerksen, P.Eng., each a Qualified
Person as defined in NI 43-101. The description of the Cozamin Mine in this document is based on assumptions,
qualifications and procedures which are set out only in the full Cozamin Report. Reference should be made to the full
text of this report, which is available in its entirety on SEDAR at www.sedar.com under the Company’s profile.

All scientific and technical information in this summary relating to any updates to the Cozamin Mine since the date of
the Cozamin Report, other than the mineral resource and mineral reserve estimates, has been reviewed and approved
by Qualified Persons who supervised the preparation of updates to elements of the Cozamin Report. These Qualified
Persons include those listed in Item 15 of this Annual Information Form.

Project Description and Location

The Cozamin poly-metallic base metal mine is located in the Morelos Municipality of the Zacatecas Mining District
near the south-eastern boundary of the Sierra Madre Occidental Physiographic Province in North-central Mexico. The
mine and processing facilities are located near coordinates 22° 48’ N latitude and 102° 35’ W longitude on 1:250,000
Zacatecas topographic map sheet (F13-6). The Cozamin property currently consists of 40 mining concessions covering
approximately 3,389 hectares.

Capstone acquired the project in January 2004. The project is 100% owned by Capstone, subject to a 3% net smelter
royalty payable to Grupo Bacis S.A. de C.V. (“Bacis”), a Mexican resource company. The Cozamin property requires
land rental and government fee payments on the mining concessions. In January 2011, taxes totalled MX$87,544 and
in July 2011, the taxes totalled MX$142,766. In January 2012, the taxes totalled MX$189,327, and in July 2012, the
taxes totalled MX$195,791. In January 2013, the taxes totalled MX$221,796.

In September 2009, Capstone Mexico entered into an agreement with Golden Minerals Company whereby Capstone
Mexico acquired three mineral claims immediately adjacent to its Cozamin Mine in Zacatecas State, Mexico. The three
mineral claims acquired (San Francisco, Santa Rita and La Esperanza) lie within the Company’s current mineral
holdings at the Cozamin Mine and immediately north of the current mining areas. Because the principal Mala Noche
vein, which hosted all of the known mineral resources and mineral reserves at that time, dips north, the Mala Noche
vein crosses on to these claims below the current mineral resources and mineral reserves.

These mineral claims were acquired from Minera Largo S de RL de CV, a wholly owned subsidiary of Golden Minerals
Company, for a purchase price comprised of (a) an upfront payment of $1.0M, (b) future cash payments of a NSR of
1.5% on the first one million tonnes of production from the acquired claims, and (c) cash payments equivalent to a
3.0% NSR on production in excess of one million tonnes from the acquired claims. The NSR on production in excess of
one million tonnes also escalates by 0.5% for each $0.50 increment in copper price above $3.00 per pound of copper.
Final registration of the assignment of rights to La Esperanza (30.19 has.) was approved by the Mexican Mines
Department in April 2010.

- 24 -

An environmental impact assessment, known in Mexico as a “Manifestacion de Impacto Ambiental”, identified acid
rock drainage and metal leaching as potential concerns manageable with appropriate mitigation measures that have
been implemented. An environmental management and monitoring program is currently underway and will be
ongoing for the life of mine. Data collected are being used to define an operational environmental management and
monitoring program, which will include appropriate environmental management and mitigation plans based on the
principle of continuous improvement. These will be reviewed and revised as necessary, on at least an annual basis,
with results reported as required to Mexican regulators.

Other issues of environmental concern relate to potential impacts comparable to those in underground mines of
similar size with flotation tailings impoundments. These include: dust, tailings handling/management, storm water
diversion, combustibles and reagent management/handling, waste management and disposal and noise. Work to
date indicates that environmental impacts are manageable. As part of this management process and best practices,
on April 2011 the company was awarded the Clean Industry Certification from Mexico’s Federal Attorney for
Environmental Protection (Procuraduría Federal de Protección al Ambiente or PROFEPA).

Prior to Capstone’s involvement in the Cozamin Mine, several environmental studies had been completed by previous
owners and the San Roberto mine had been permitted to operate at 750 tpd. Capstone formally received its
operating permit on October 20, 2006. This is known in Mexico as a Licencia Única Ambiental (“LUA”). A LUA for the
tonnage expansion to 2,600 tpd was received on March 25, 2008. On January 19, 2009, application was made to
modify the LUA for the tonnage expansion to 3,000 tpd, which was granted in May of that year. In January of 2011,
further application was made to increase the permitted throughput from 3,000 tpd to 4,000 tpd, which was granted in
November of 2011.

Accessibility, Climate, Local Resources, Infrastructure and Physiography

The Cozamin Mine is located 3.5 km to the NNE of the city of Zacatecas, the Zacatecas state capital. The municipality
of Zacatecas has a population of approximately 130,000 people. Other communities in the immediate vicinity of the
project include the following: Hacienda Nueva (3 km W), Morelos (5 km NW) and Veta Grande (5 km N). The Cozamin
Mine is accessible via paved roads to the project area boundary where good, all-weather roads provide access to the
mine and most of the surrounding area. The project area falls within the Hacienda Nueva and La Pimienta Ejido
concessions.

The Cozamin Mine has excellent surrounding infrastructure including schools, hospitals, railroads, and electrical
power. The Company has access to a power line and substation that allows the Company to draw up to 7.5 MW from
the national power grid. Generators (both operating and back-up) on site have a capacity of 2.0 MW. The ultimate
capacity of the current tailings pond at the Cozamin Mine is an additional 9.5 M tonnes. Permits are not currently
issued for all of these additional raises to the tailing facility. There is an adequate source of personnel that avoids the
necessity of “expat” employees.

The climate in the region is semi-arid with maximum temperatures of approximately 30°C during the summer season
and minimum temperatures in the winter season producing freezing conditions and occasional snow. The rainy
season extends from June until September. The average annual precipitation is approximately 500 mm. As the
certainty of runoff into the tailings pond cannot be predicted, additional water resources have been secured, with
further water rights undergoing evaluation.

The Cozamin Mine is located in the Western Sierra Madre Physiographic Province near the boundary with the Mesa
Central Province (Central Plateau Province). The Zacatecas area is characterized by rounded NW trending mountains
with the Sierra Veta Grande to the north and the Sierra de Zacatecas to the south. Elevations on the property vary
from 2,400 m to 2,600 masl. The Zacatecas area is located between forested and sub-tropical regions to the
southwest and desert conditions to the northeast. The climate in the region is semi-arid. Vegetation consists of
natural grasses, mesquite or huizache and crasicaule bushes. Standing bodies of water are dammed as most streams
are intermittent.

History

In pre-Hispanic times, the area was inhabited by Huichol Indians who mined native silver from the oxidized zone of
argentiferous vein deposits in the Zacatecas Mining District. During the Spanish Colonial era, in 1548, production
commenced at 3 mines: the Albarrada mine on the Veta Grande system, and the San Bernabe mine and Los Tajos del
Panuco on the Mala Noche vein system. The initial operations worked only the oxides for silver and some gold, and
later the sulphide zones were worked for base and precious metals.

During the Mexican Revolution (1910-1917), mining was essentially halted with flooding and cave-ins limiting access.
From 1972, Consejo de Recursos Minerales (“CRM”) worked mines in the El Bote, La Purisima and La Valencia zones.
Historic production from the Zacatecas district is estimated by the CRM (1992) to be 750 million ounces of silver from
20 million tonnes grading over 900 g/t Ag and approximately 2.5 g/t Au. Lead, zinc and copper have also been
recovered but the production and grades were not estimated.

Minera Cozamin was established in 1982 by Jack Zaniewicki who consolidated concession holdings over the Mala
Noche vein and operated the San Roberto Mine and plant at 250 t/d until October 1996. During this period, Industrias
Peñoles S.A. de C.V. (“Peñoles”) undertook exploration in the district but did not buy any significant concessions. In
all, it is estimated that 1.2 million tonnes of ore were mined and processed at the Cozamin Mine prior to October
1996.

In October 1996, Zaniewicki sold Cozamin for $6.8M to Minera Argenta, a subsidiary of Bacis. Bacis expanded the mill
to a 750 tpd flotation plant, and processed 250,000 tonnes of ore grading 1.2% Cu, 90 g/t Ag, 0.5 g/t Au, 1.8% Zn and
0.6% Pb from 1997 to the end of 1999. Bacis developed resources principally by drifting and raising on the Mala
Noche vein within the San Roberto (Cozamin) mine. Diamond drilling was only used as an exploration tool to identify
areas with mineralization peripheral to the developed mine workings. At the end of 1999, Bacis had historic (not 43-
101 compliant) resources at San Roberto in all categories that totalled about 6 million tonnes grading about 1% Cu,
0.9% Pb, 3.2% Zn and silver in the range of 85 g/t to 105 g/t.

In 1999, Bacis closed the mine. The principal factors that resulted in the mine closure were low metal prices and
under capitalization. Capstone then commenced field work in March 2004 and surface drilling one month later.

In November 2004, the mine was dewatered and exploration drilling continued from underground. The hoist, shaft
and mine infrastructure were sufficiently rehabilitated in January and February 2005 to allow for the development of
the first cross cuts for underground drilling which commenced in March 2005. Initial metallurgical studies by SGS
Lakefield and PRA were received in January and a feasibility report for the project was completed in February 2006.
The first phase of underground drilling was completed in April, 2006.

An independent study of geological resources at Cozamin was completed in October 2005 and a second resource
estimate study was completed in June 2006. The mine and plant were commissioned in July 2006 and quickly reached
an average daily production rate of 1,000 t/d. Mine and plant capacity was then doubled by July 2007. Daily
production at Cozamin was increased to 3,000 t/d in late 2008 and maintained at just above that level to 2012
(3,200 t/d).

Geological Setting

The Zacatecas Mining District covers a belt of epithermal and mesothermal vein deposits that contain silver, gold and
base metals (copper, lead and zinc). The district is in the Southern Sierra Madre Occidental Physiographic Province
near the boundary with the Mesa Central Physiographic Province in North-central Mexico. The dominant structural
features that localize mineralization are presumed to be of Tertiary Age, and are interpreted to be related to the
development of a volcanic centre and to northerly trending basin-and-range structures.

The Zacatecas Mining District occurs in a structurally complex setting, associated with siliceous subvolcanic and
volcanic rocks underlain by sedimentary and meta-sedimentary rocks. The geologic units of the Zacatecas area include
Triassic metamorphic rocks of the Zacatecas Formation and overlying basic volcanic rocks of the Upper Jurassic or
Lower Cretaceous Chilitos Formation. The Tertiary rocks consists mainly of a Red Conglomerate unit deposited in

- 26 -

Paleocene and/or Eocene times, and overlying rhyolitic tuff and intercalated flows that were deposited from Eocene
to Oligocene times. Some Tertiary rhyolite bodies cut the Mesozoic and Tertiary units and formed flow domes.

The Zacatecas Formation, a marine Upper Triassic unit, consists of sericite schists, phyllites, slates, quartzites,
metasandstone, flint, metaconglomerate and recrystallized limestone and represents the oldest rocks in the district.

The host rocks for the Mala Noche vein are intercalated carbonaceous meta-sedimentary rocks and andesitic volcanic
rocks ranging in age from the Triassic Period to the Cretaceous Period, and Tertiary Agerhyolite intrusive rocks and
volcanic flows. Mineralization in the Mala Noche vein appears to have been episodic. A copper-silver dominant phase
was one of the last stages of mineralization at Cozamin. In general, this copper-silver phase was emplaced into an
envelope of pre-existing vein hosting moderate to strong zinc and lead mineralization and moderate silver
mineralization. Thus, the host lithology to the vein does not appear to have influenced the strength of the copper-
silver phase of mineralization which is typically enveloped by earlier vein material.

In the underground workings at Cozamin, the Mala Noche vein has been shown to occupy a system of anastomosing
faults that is principally comprised of the Mala Noche and Elabra faults along with other less significant faults.
Although not all of the fault system is mineralized at any given location, there have been no other significant
mineralized fault zones discovered to date.

The Mala Noche is the principal fault associated with mineralization at Cozamin. In the San Roberto Mine, the Mala
Noche strikes WNW (N70-80W) and the dip varies from 38° to 90° to the north. There is a clear association of higher
copper grades with steeper dips of the Mala Noche fault. Where the Mala Noche is weakly mineralized, it appears
that the principal alteration in this fault is mostly quartz-pyrite.

Exploration

In 2004, Capstone decided to drill test the Mala Noche vein beneath the historic workings of the San Roberto mine.
The initial three drill sections, comprised of two drill holes each, all intersected significant economic mineralization
over true widths varying from 3.2 m to 14.9 m. These three drill sections were distributed over 550 m of strike extent
beneath the historic workings. At that point, Capstone decided to drill single hole sections every 100 m beneath the
San Roberto workings. These holes targeted the Mala Noche vein at approximately 2,150 masl which is 65 m below
the historic workings. This strategy resulted in the first 20 exploration holes being distributed over a strike length of
1.4 km. Of these first 20 drill holes, 17 intersected significant mineralization that averaged 6.64 m in true width and
had weighted grade averages of 2.61% Cu, 91.25 g/t Ag and 1.38% Zn.

These significantly higher copper grades and undiminished silver grades are associated with significant amounts of
pyrrhotite. This reinforced the Company’s conviction that the historic workings at San Roberto are located just above
the upper reaches of a large copper-silver mineralized system of mesothermal character. Subsequent exploration
drilling showed that the copper-silver dominant phase of mineralization extends below 1,865 masl which is 350 m
below the historic workings.

From 2004 until later 2009 the Company focused exploration on the main Mala Noche Vein (“MNV”) system where
underground drilling targeted areas in the San Roberto area that needed infill drilling to attain a higher level of
confidence and a higher resource classification as steps to completing a mineral reserve estimate. A similar approach
was taken with surface drilling, focusing on the San Rafael area of the Mala Noche system to the East of the
San Roberto Mine.

In 2010, the Company discovered a new zone of high grade copper-silver mineralization called the Mala Noche
Footwall Zone (“MNFWZ”). Located in a structure that splays at about 30˚ on the footwall side from the main
mineralization, the MNFWZ is still being tested. The zone is more than 700 m long in the strike direction and locally
between 200-500 m in the dip direction and is still open to the east and down dip. The structure is also open locally
up dip but it appears to be transitioning to more zinc dominated mineralization and thus presents a lower value target
in that direction. In the west the MNFWZ merges with the MNV and is considered largely closed in that area.

The MNFWZ is a significant exploration target and was the biggest driver for the 2011 and 2012 exploration programs;
infill and step-out drilling at MNFWZ continued in 2013. Because the MNFWZ splays obliquely from the MNV, where it
is being mined, and in close proximity to the main haulage ways of the Cozamin Mine, it presented an attractive
exploration target that could transition readily into the development stage. In 2011, two cross-cuts were driven from
the producing mine into the MNFWZ on two different levels and two drifts were driven east and west for 38 m and
310 m respectively on level 12.8 and 133 m and 235 m also east and west respectively on level 12. By December 31,
2011 more than 60,000 tonnes of development ore at a grade of 2% copper was mined from this drift, opening up the
structure for mapping continuity of grade and providing material for metallurgical testing. By December 31, 2012 the
MNFWZ was further developed on sub-levels 12.5, 13.2 and 12.8 with back cuts in levels 12W, 12.5 and 12.8
producing a total of 107,356 tonnes at a grade of 1.93% copper. By December 31, 2013 the production in MNFWZ was
172,877 tonnes at grade of 1.95% copper in 12.5 long hole stope, L12, 12.8, L13,13.2, 13.5, 13.8, 14.5 and 14.8 stopes.

Mineralization

All mineralization at the Cozamin Mine occurs in veins. The main stage of copper-dominant stage of mineralization at
the Cozamin Mine can be classified as intermediate sulphidation, high temperature epithermal transitioning at depth
to more mesothermal-like mineralization. The copper-dominant stage of mineralization appears to cut across earlier
more clearly epithermal zinc-dominant mineralization. The epithermal veins display well banded quartz veins and
open space fillings and quartz druse vug linings. The higher temperature veins have significantly less vugs, and the
veins can be massive pyrrhotite-pyrite-chalcopyrite.

This transition from epithermal zinc dominant mineralization to copper-dominant mesothermal mineralization is
thought to be the result of an evolving, telescoping hydrothermal system that was epithermal in its early stages and
became mesothermal as the hydrothermal migrated upwards. Chalcopyrite-pyrite-pyrrhotite mineralization can be
seen to cut earlier sphalerite-galena-pyrite mineralization in drill core and workings. Zones of massive pyrrhotite
along with apparent retrograded calcsilicates suggest mineral deposition in a mesothermal environment that was
superimposed on epithermal alteration and mineralization. This telescoping hydrothermal system is closely associated
with the district’s largest center of rhyolite flow domes that may be the upward expression of a felsic stock.

The dominant mineralized vein on the Cozamin Mine is the Mala Noche. This vein has been traced for 5.5 km on
surface on the property. It strikes approximately east-west and dips on average at 60° to the North. There are at least
18 shafts that provide access to the historical workings at Cozamin. The largest of these is the San Roberto mine
which has a strike length of 1.4 km. Mineralization peripheral to these workings was the principal target of Capstone’s
exploration at Cozamin.

The Mala Noche vein system occupies a system of anastomosing faults. The mineralized bodies within the Mala
Noche appear to be strongest where the disparate faults coalesce into a single fault zone. Results from the
exploration and mine development to date indicate that some of the strongest mineralization in the San Roberto mine
rakes to the west at approximately -50° within the vein. Post mineralization offsets of the Mala Noche vein are
minimal and occur along high angle, normal faults that strike northeast.

Moderate propyllitic wall rock alteration is generally limited to 3 m into the hanging wall and footwall. Gangue
minerals in the Mala Noche vein consist of quartz, silica, calcite, chlorite, epidote and minor disseminated sericite.

- 29 -

The quartz occurs as coarse grained druse coarse crystalline masses, and a stockwork of quartz veinlets.
Mineralization in the Mala Noche vein at the Cozamin Mine appears to have been episodic. Early epithermal
mineralization and alteration (represented by sulphide pseudomorphs of carbonates and possibly barite and well-
banded quartz veins and vug linings of quartz druse) have been overprinted by higher temperature pyrite-pyrrhotite-
chalcopyrite dominant mineralization in a telescoped, intrusive related hydrothermal system. The Mala Noche vein in
the San Roberto mine workings shows contained sulphides to occur as disseminations, bands and masses. Considering
the limited exposure of the copper-silver phase of mineralization in the current depths of the mine workings,
conclusions about mineralization styles at this point in time are preliminary.

Pyrite is the dominant vein sulphide and typically comprises approximately 15% of the Mala Noche vein in the San
Roberto mine. It occurs as fine disseminations and veinlets, coarse crystalline replacements, and pseudomorphs of
possible epithermal carbonates such as barite and calcite. Pyrrhotite is the second most common sulphide mineral
but is present only in the intermediate and deeper levels of the San Roberto mine. It occurs as replacement masses,
pseudomorphs of platey masses and acicular replacements probably after amphibole. Pyrrhotite commonly occurs as
an envelope to, or intermixed with, strong chalcopyrite mineralization.

Chalcopyrite is the only copper sulphide recognized megascopically at the Cozamin Mine. Like pyrrhotite, it is more
common at the intermediate and deeper levels of the mine. It occurs as disseminations, veinlets and replacement
masses. These masses appear to be fractured and brecciated at intermediate levels in the mine.

Sphalerite is the dominant economic sulphide in the upper levels in the San Roberto mine. Most of the sphalerite is
marmatitic. It occurs as disseminations and coarse crystalline masses and is commonly marginal to the chalcopyrite-
dominant portion of the vein.

Galena is less common than sphalerite but is generally associated with it. Where it is abundant, it occurs as coarse
crystalline replacement masses. Both coarse and fine crystalline masses of galena are argentiferous.

Arsenopyrite typically occurs as minor, microscopic inclusions in pyrite. Argentite is the most common silver mineral.
It has been identified microscopically occurring as inclusions in chalcopyrite and pyrite. Assays indicate that silver is
also probably present in sphalerite and galena.

Bismuth and silver selenides occur as inclusions predominantly in chalcopyrite and pyrite. The main gangue minerals
are quartz and calcite with rhodochrosite, barite and gypsum also reported.

Drilling

In all, 178 surface and 226 underground exploration holes have been drilled at the Cozamin Mine in the period from
April 2004 through November 2012 targeting the MNV, which is the cut off for the current mineral resource and
mineral reserve estimates. From April 2004 through 2008, 59 surface holes have targeted San Rafael. Since 2010, 118
underground holes and 6 surface holes have targeted the MNFWZ. In 2013, 33 underground holes targeted the
MNFWZ and intersected the MNV where possible. 124 holes from 2012 are included in the most recent mineral
resource estimate; a mineral resource estimate including 2013 drilling is underway.

Drill holes are located using a total station TRIMBLE instrument, model S6. Down hole survey readings were recorded
using either an Eastman Single Shot, FLEXIT SensIT or Reflex EZShot instrument. Survey readings are generally taken
every 50-150 m for surface holes and every 50-100 m for underground holes. Survey results have been corrected for
magnetic declination (+8º). Dip variations in surface holes are not more than 5.3º, with an average value of 1.1°. The
maximum down hole dip variation in the underground holes is 15.4º with an average variation of 1.3°.

The Phase I and II surface exploration drill programs totalled 17,967.71 m of NQ-diameter diamond core in 37 holes
that were drilled in 2004 and the first quarter of 2005. The Phase III underground definition drill program consisted of
114 holes that totalled 17,736.31 m of NQ-diameter diamond core that were drilled in 2005 and the first half of 2006.

Phases IV and V surface drilling commenced in October 2006 and was completed in April 2007. The five surface holes
were drilled with PQ-diameter rods to approximately 300 m, reduced to HQ rods to about 700 m and then reduced
again to NQ rods. A total of 4,824.5 m were drilled and 304 samples assayed copper, silver, lead, zinc and gold at
ALS Chemex in Vancouver. Underground NQ-diameter drilling commenced in November 2006 and was completed in

QA/QC were sent to SGS Lakefield in Toronto. Underground NQ-diameter drilling, 52 holes were drilled for a total of
11,909 m. Assaying of 5,032 samples for copper, silver, lead, zinc and gold was carried out by ALS Chemex in
Vancouver.

Phase VIII surface and underground drilling commenced in January 2011 and was completed in December 2011. The
22,286 m of underground drilling (holes CG-11-U250 to CG-11-U293) targeting the MNFWZ were also drilled with NQ-
diameter for a total of 43 holes, Assaying of 8,066 samples for copper, silver, lead, zinc and gold was carried out by
ALS Chemex. The 20,330 m of surface drill holes were done through twenty-one holes with HQ rods and, where
necessary, reduced to NQ rods. A total of 6,777 samples were assayed for copper, silver, lead, zinc and gold.

Phase IX underground drilling commenced in January 2012 and was completed in November 2012. The 27,083 m of

where necessary, reduced to NQ rods. Assaying of 5,660 samples for copper, silver, lead, zinc, and gold was carried
out by ALS Chemex (2,337 samples) and the on-site laboratory (3,323 samples). The 5,056 m of surface drill holes
were done through five holes with HQ rods, and, where necessary, reduced to NQ rods. Assaying of 440 samples for
copper, silver, lead, zinc, and gold was carried out by ALS Chemex (107 samples) and the on-site laboratory (333
samples).

Phase X underground drilling commenced in January 2013 and was completed in December 2013. The 19,836 m of
underground drilling targeting the MNFWZ/MNV in 33 holes (holes CG-13-341 to CG-13-373) were drilled with HQ
rods, and where necessary, reduced to NQ rods. Assaying of 2,199 samples for copper, silver, lead, zinc, and gold was
carried out by ALS Chemex (1,301 samples) and the on-site laboratory (898 samples).

Sampling and Analysis

Two sampling methods are presented in the Cozamin Report: drill core cutting and underground chip sampling.

Capstone employees are responsible for the all on-site sampling of drill core. Analysis of these samples is done at
accredited outside laboratories. Channel samples are prepared by Capstone employees for analysis at the on-site
laboratory. Duplicate quality control samples (coarse crush and pulp) are prepared by Capstone employees for
analysis at an off-site laboratory. Blind samples comprised of standard reference material are included in the sample
streams.

The sample interval for drill core cutting does not exceed 0.5 m in the vein and 2 m in the wallrock. Very high grade
intervals are marked out and sampled separately from lower grade zones. Sample boundaries are based on mineral
proportions and/or texture (e.g. massive versus disseminated). However, sample intervals are not less than 0.25 m in
length.

As at the date of the Cozamin Report, samples are sent to ALS Chemex in Hermosillo for preparation. Upon receipt,
samples are inspected for any irregularities. Samples are then dried, weighed, crushed. Two hundred and fifty grams
is split and pulverized to at least 85% passing 75 microns. Reject material is retained at ALS Chemex in Hermosillo in a

- 31 -

cold storage facility. Prepared pulps are sent to ALS Chemex in Vancouver for primary analysis. Check sample pulps
are sent to SGS in Toronto for analysis.

At ALS Chemex, gold and silver were analyzed by fire assay with a gravimetric finish using a 50 g charge. The detection
range for this method is 0.05 ppm to 1,000 ppm Au and 5 ppm to 10,000 ppm Ag. Silver was also analyzed with
copper, lead and zinc using a four-acid digest by inductively coupled plasma-atomic emission spectroscopy (ICP-AES).
The detection ranges with this method are: 1 ppm to 1,500 ppm Ag and 0.001 ppm to 10,000 ppm for Cu, Pb and Zn.
Samples with over limit lead results are re-analyzed using the CON02 method in which the sample undergoes a four
acid digest producing a lead sulphate that undergoes titration for determination of the lead content. Two samples
from Phase V had over limit results (23% to 27% lead). At their lead values, the tolerance level for reporting the grade
with the titration method is ±2.5%.

At SGS, gold is analyzed by fire assay with an atomic absorption finish using a 30 g charge. The detection range for this
method was 5 ppb to 2,000 ppb. Silver was analyzed from a 2 g charge using a multi-acid digest with atomic
absorption finish (0.3 g/t to 300 g/t Ag detection range). Over limit results were re-analyzed by fire assay with an
atomic absorption finish using a 50 g charge. Copper, lead and zinc are analyzed by inductively coupled plasma-optical
emission spectroscopy (ICP-OES) using a four acid digest. Detection limits are: 10 ppm to 10% for copper, 20 ppm to
10% for lead and 10 ppm to 10% for zinc. Over limit results are reanalyzed using the same method but with a sodium
peroxide fusion. The over limit detection limit is 0.01% for each metal.

Blanks, standards and pulp duplicates were inserted into the series of underground drill core samples submitted for
assay. Typically, standard and blank samples were placed at the start and finish of the mineralized interval within a
hole. Approximately two sample intervals per hole were selected to have pulp duplicates prepared, and another two
intervals per hole were selected for preparation of core duplicates. Additional quality control samples were inserted
into the sequence as deemed necessary, e.g. a blank inserted in the sample sequence after a sample expected to have
very high grade to monitor the quality of the assays.

With regard to underground channel sampling, chip samples up to 20 cm wide are collected along the marked sample
line. The line number and sample interval are clearly entered in the sample book. Two stubs are placed in the sample
bag by the sampler. The sample books are archived at the Cozamin Mine.

The underground channel samples were analyzed at both SGS Toronto (using the same methods as the drill core
samples) and at the on-site lab at Cozamin prior to mid-2006. SGS Toronto was used as the primary laboratory and
the site laboratory as a check. Pulp samples were analyzed on-site by fire assay with an atomic absorption finish for
copper, silver, lead, zinc and iron. From mid-2006 the Cozamin site laboratory has been used as the primary
laboratory and check samples sent to SGS in 2006 and ALS Chemex in 2007. The same methods described for the drill
hole samples have been used for the underground check samples submitted to SGS and ALS Chemex.

Blanks, standards and pulp duplicates were inserted into the series of underground samples submitted for assay.
Standard and blank samples are inserted into the sample sequence approximately 1 in 15 samples, and pulp duplicates
every 20 samples. Additional quality control samples were inserted into the sequence as deemed necessary.

Although the author of the Cozamin Report has not visited the assay labs used to analyze Cozamin samples, they are
reputable facilities which have been monitored using an appropriate QA/QC program. In the opinion of the author,
the sample preparation, analysis and security practises follow accepted industry standards and the results
demonstrate an acceptable level of analytical accuracy and precision. The results of the data verification indicate that
the database is sound and reliable for the purposes of resource estimation.

Security of Samples

While at the on-site laboratory, only Capstone employees are allowed in the core shack when unsampled core is laid
out waiting to be cut. No person other than the geologist responsible for logging is allowed to handle the core prior to
sampling. The geologist takes great care to ensure that core is returned to the box in the same position and
orientation from which it came. Visitors to the core shack must be accompanied by a Capstone employee. A
minimum of ten consecutive samples are placed in order in a large sack. The sack is sealed with tape and by a
numbered seal that prevents opening the sack without damaging the seal. The sample number series of the enclosed

- 32 -

samples are clearly written on the exterior of the sack. The batch number, the serial numbers of the seals and the
corresponding sample number series are written on the transmittal form to be sent to the preparation laboratory.

Mineral Resource and Mineral Reserve Estimates

At year end 2012 update to the mineral resource estimate for San Roberto was completed by independent consultant
Ali Shahkar, P.Eng, Principal Consultant of Lions Gate Geological Consulting Inc. (“LGGC”), using accepted industry
standard methods conforming to NI 43-101 requirements. The Mineral Resource estimates for the end of 2013

The original 2009 mineral resource estimate for the San Rafael deposit was completed by Capstone staff under the
supervision of independent consultant Robert Sim, P.Geo., of SIM Geological Inc., using accepted industry standard
methods that conform to NI 43-101 requirements. This block model was re-tabulated based on the current NSR
formulae by independent consultant Ali Shahkar, P.Eng, Principal Consultant of LGGC. For the tabulation of the
remaining Mineral Resources for the end of year 2012. There has been no mining activity in San Rafael in 2012 or
2013. As such, the Mineral Resource estimates for San Rafael tabulated below remained unchanged.

The mineral resource estimate for the MNFWZ deposit was prepared by independent consultant Ali Shahkar, P.Eng.,
Principal Consultant of LGGC, in February 2013, using accepted industry standard methods conforming to NI 43-101
requirements. This model was depleted for all mining activity to the end of 2013 to produce the remaining Mineral
Resource estimates stated below.

In each case, estimated mineral resources exclude all historical (pre-Capstone) and Capstone underground production
conducted through December 31, 2013. Mineral resources are constrained by the Capstone property boundary.

The Cozamin mineral resource estimates for the San Roberto and MNFWZ areas are reported in the following table
above a $35 per tonne cut-off.

During 2013, extraction of the MNFWZ proven and probable reserves was advanced using a cut and fill and longhole
mining method. During the year, detailed mine planning was completed to add mineral reserves to the MNFWZ based
on the updated mineral resource estimation completed in March 2013. Stantec Consulting LLC of Tempe, Arizona
supervised and reviewed the work completed by Cozamin. The MNFWZ mineral reserves stated below is based on the
mineral reserves addition and the subsequent depletion due to the mineral extraction in 2013.

San Roberto mineral reserves have changed based on depletion due to mineral extraction in 2013. San Rafael
Reserves remained the same during the year due to no mining activity in the area. The year end 2013 updated mineral

The mineral reserve balance for Cozamin is summarized in the table above. During 2013, operations continued to
extract mineralized material primarily in the copper zones. An engineering change occurred in 2013 to include new
mineral reserves located in the MNFWZ. Stantec Consultaing LLC of Tempe, Arizona supervised and reviewed the
work completed by Cozamin.

Reconciliation

Reconciliation activities were conducted to determine the accuracy of the Mineral Reserve block model (model) to the
mine reported production. The results indicate that although production tonnage matched model prediction,
Cozamin produced more copper and silver than predicted by the model. Therefore, the copper and silver grades
identified in the model are considered to be conservative and may understate respective contained metals. Block
model parameters are under review to address this variance. There was a nominal variance in the 2013 mine and mill
reconciliation for tonnage and grade.

Mining Operations

The Cozamin Mine commenced operation in June 2006 and since that time has maintained continuous production and
has shown continual improvement. Since the start of operations, the mill has undergone numerous upgrades,
expansions and operating optimizations. The mine has seen improved access, ventilation and an increase in its mobile
equipment fleet. The ore is planned to be extracted using three mining methods: cut and fill using waste rock fill,
longhole open stoping and Avoca - a hybrid of longhole and cut and fill methods. Each method has been assigned to
individual mining blocks depending on the physical characteristics of the veins and its suitability to one of the above
methods.

Development mining and equipment usage was estimated based on the mine production schedule. Capital
development is conducted using a Mexican-based contractor. All other mining at Cozamin is done using Capstone
employees, equipment and facilities.

The mine extends for a strike length of over 1 km and mineral reserves extend to a depth of 700 m. Access to the
underground workings is via two service and haulage ramps and a hoisting shaft.

The LOM plan production rate is 1.2 million tpy and is supported by the operating results of 2012 and 2013.

During 2013, a total of 81,351 dmt of copper concentrates, 2,205 dmt of lead concentrates and 16,928 dmt of zinc
concentrates were shipped and recorded as revenue.

From January to December 2013, the mine processed a mill feed of 1,206,383 tonnes of ore grading 1.86% copper,
1.12% zinc, 0.19% lead and 61.0 g/t silver. The average production rate was approximately 3,305 tpd during that

- 35 -

period. The mine produced 45.52 million pounds of copper, 17.85 million pounds of zinc, 2.73 million pounds of lead
and 1.68 million ounces of silver.

The Cozamin Mine’s applicable taxes include the following:

•

Corporate Taxes - the Mexican corporate income tax is at a 30% rate applied on net revenue (profit) after
depreciation. The 2013 Mexican Tax Reform repealed the 17.5% IETU Tax (Impuesto Empresarial Tasa Unica)
effective for Cozamin’s 2014 taxation year.
A value added tax is payable to the Mexican government. The amount paid in any given year is 100%
refundable, and may be used to offset income tax.
The 2013 Mexican Tax Reform introduced a 7.5% mining royalty. The royalty, effective January 1, 2014, will
be applied on the positive difference between income arising from sales related to mining and the deductions
permitted by the Income Tax Law, not including deductions on investments (except those involved in mining
prospecting and exploration), interest payable and the annual inflation adjustment.
Property taxes are approximately $20,000 per year.

The payback period for the entire project capital spent to date was completed within the first two years of operation.
The payback on all future capital spending will be almost immediate due to large cash flows and minimal capital
expenditures planned.

The LOM plan currently has the mine being depleted of current reserves in 2021. There are several potential resource
areas that may, if shown to be economic, add life to the mine but these are not yet at a stage where they can be
classed as reserves. It must be noted that these mineral resources may not be found to present potential for
economic extraction. The reader is cautioned not to assume that all or any part of mineral resources will ever be
converted into reserves or mined, and it should further be understood that “inferred resources” have a great amount
of uncertainty as to their existence and as to whether they can be mined legally or economically. It cannot be assumed
that all or any part of mineral resources will ever be upgraded to a higher category.

The closure cost for the Cozamin Mine was re-estimated and updated in December 31, 2013, totalling $9.1M at the
end of operations including 5 years of post-closure monitoring.

Exploration and Development

The Mala Noche Footwall Zone continued to be the exploration driver in 2013. An in-fill drilling program completed in
2012 increased the indicated resource estimation in the latest Mineral Resource estimate. This material will be used
in engineering studies aimed at increasing Mineral Reserves and as such represents a major upside opportunity at
Cozamin for either increased mine life or increased throughput or some combination of both scenarios.

The majority of the 2013 exploration budget is aimed at converting some of these Inferred Resources to Indicated
Class or better by infill drilling from underground. Further underground drilling is also needed to test down dip and
along strike to the east from the current resource area where the MNFWZ deposit remains open to expansion
possibilities. After the MNFWZ drilling program is complete, additional drilling will target the main MNV mineral
resource/mineral reserve area in areas where the mineralization appears to be open.

Minto Mine (Yukon)

The Minto Mine is the subject of a report titled “Minto Phase VI Preliminary Feasibility Study Technical Report” dated
July 31, 2012 with an effective date of January 1, 2012 (the “Minto Report”). This technical report was compiled by
Minto Explorations Ltd. and written by Brad Mercer, P.Geol., John Sagman, P.Eng., Wayne Barnett, Pr.Sci.Nat., John
Eggert, P.Eng., Bill Hodgson, P.Eng., Garth Kirkham, P.Geo., Mike Levy, PE, Pooya Mohseni, P.Eng., Bruce Murphy,
P.Eng., and Colleen Roche, P.Eng., each a Qualified Person as defined in NI 43-101. The description of the Minto Mine
in this document is based on assumptions, qualifications and procedures which are set out only in the full Minto
Report. Reference should be made to the full text of this report, which is available in its entirety on SEDAR at
www.sedar.com under the Company’s profile.

- 36 -

All scientific and technical information in this summary relating to any updates to the Minto Mine since the date of the
Minto Report has been reviewed and approved by Qualified Persons who supervised the preparation of updates to
elements of the Minto Report. These Qualified Persons include those listed in Item 15 of this Annual Information
Form.

Project Description and Location

The Minto Mine is located in the Whitehorse Mining District in the central Yukon. The property is located
approximately 240 km northwest of Whitehorse, Yukon’s capital. The project consists of 164 quartz claims covering
an area of approximately 2,760 ha.

The project is roughly centred on NAD 83, UTM Zone 8 coordinates 6,945,000 mN, 385,000 mE. The mine is located
on the west side of the Yukon River on Selkirk First Nation (“SFN”) Category A settlement land (SFN Parcel R-6A).

The 100% registered owner of the 164 claims is Minto Explorations Ltd. (“MintoEx”), a 100% owned subsidiary of the
Company. The status of the claims has been recently confirmed with the Mining Recorder, as having expiry dates
ranging between March 1, 2017 and October 7, 2028. The lease, but not the claim boundaries, has been surveyed by
an authorized Canada Lands Surveyor in accordance with instructions from the Surveyor General.

There are no known back-in rights, payments or other agreements or encumbrances to which the property is subject
other than a recently amended Cooperation Agreement with the SFN and a net smelter royalty payable to the SFN.

Environmental liabilities at the Minto Mine relate to the dry stacked tailings facility and waste rock dumps as well as
some water stored at the site that is impacted by operations and to the removal of all operational infrastructures. A
closure plan has been developed and approved (most recently on September 9, 2011) detailing methods and costs
associated with restoring the site to an acceptable environmental standard. Engineered covers will be placed on
tailings and waste rock such that interactions with surface water are minimized. Active water treatment will not be
required as passive treatment systems are planned to be utilized. A $23.9M surety bond has been put in place with
the Yukon Government in accordance with a territorial closure and reclamation policy. The closure plan and related
letter of credit amount are reviewed on a bi-yearly basis.

MintoEx has obtained a variety of permits in order to conduct ongoing work on site and the Company is in the process
of obtaining additional approvals associated with expanded operations and mine life. The major instruments or
authorizations permitting and governing operations for the project include a Type A Water Use Licence, issued by the
Yukon Water Board and a Quartz Mining Licence issued by the Yukon Government, Energy Mines and Resources.
MintoEx has received a portion of the permits necessary to extract ore from additional mining areas, for higher plant
throughput, revised waste and tailings management facilities and other environmental aspects of the project. At this
time, MintoEx is confident that the additional permits to access the new deposits and waste management facilities will
be granted after the government authorities have completed their reviews.

Accessibility, Climate, Local Resources, Infrastructure and Physiography

The Minto Mine is accessible via the Klondike Highway (No. 2) to Minto Landing on the East side of the Yukon River.
At Minto Landing, the mine operates a barge across the river in the summer months and constructs an ice bridge in
the winter. The barge has the capacity to carry one B-train transport trailer and truck. There is typically a 6 to 8 week
period during each break-up and freeze-up of the Yukon River when there is no access across the river. A 27 km long,
all-weather gravel road provides access from the West side of the Yukon River to the project site.

The mine access road crosses one major tributary of the Yukon River, Big Creek, via a single-lane steel span bridge
made with reinforced concrete abutments and deck. The highway, river crossing and gravel mine access road are
suitable for heavy transport traffic.

When access across the Yukon River is available, operations personnel are transported to the site in commercial buses
based out of Whitehorse. During the river freeze and thaw periods, personnel are transported from Whitehorse via
charter air services that land on the 1,300 m airstrip located at the mine.

- 37 -

The climate in the Minto area of the Yukon is considered sub-arctic with short cool summers and long cold winters.
The average temperature in the summer is 10°C and the average temperature in the winter is -20°C. Average
precipitation is approximately 25 cm of rain equivalent per annum in the form of rain and snow. The weather does
not impede year round operation of the mine and processing plant except in short periods of harsh cold temperatures
(-50°C) that can cause open pit mining operations to be temporarily suspended.

The property lies in the Dawson Range, part of the Klondike Plateau, an uplifted surface that has been dissected by
erosion. Local topography consists of rounded rolling hills and ridges and broad valleys. The highest elevation on the
property is approximately 1,000 masl, compared to elevations of 460 m along the Yukon River. Slopes on the property
are relatively gentle and do not present accessibility problems. Bedrock outcrops can often be found at the tops of
hills and ridges. There are no risks of avalanche on the property.

Vegetation in the area is sub-Arctic boreal forest made up of largely spruce and poplar trees. The area has
experienced several wildfires over the years, the latest in 2010, and has no old-growth trees remaining. The fire in
2010 led to the partial evacuation of the camp and a short stoppage in production.

The nearest services, including fuel, groceries, hotel, restaurant and clinic, are at Carmacks, approximately 75 km
south of Minto on Highway 2. Some services are available at Pelly Crossing, 35 km to the East of Minto. The nearest
large community is Whitehorse, with a population of approximately 27,000. It is serviced with commercial flights daily
from Vancouver, Edmonton and other northern communities. Whitehorse is also connected via paved highways to
British Columbia to the South, to Alaska to the West and to the port of Skagway to the Southwest, where Minto
concentrate is trucked for loading onto ocean-going vessels.

The Minto Mine has sufficient power, water, camp and personnel to continue operations through the life of mine
plan.

History

In 1970, a joint venture between Silver Standard Mines Ltd. and Asarco Inc. conducted a regional stream sediment
geochemical survey in the area. In 1971, DEF claims were staked by United Keno Explorations. That same year a joint
venture formed with United Keno Hill Mines, Falconbridge Nickel and Canadian Superior Explorations, to cover follow-
up prospecting. IP and VLF-EM geophysical surveys, soil sampling and mapping on the DEF claims followed. In June
1973, a main mineralized body was discovered. In 1974, a winter road was built from Yukon Crossing and 58 diamond
drill holes (11,228 m) on the Minto claims were drilled. From 1975-1976 joint feasibility studies were conducted.

In 1984, Silver Standard changed its name to Consolidated Silver Standard and transferred its interest in the Minto
claims to Western Copper Holdings, a subsidiary of Teck Corp. In 1989, Western Copper Holdings transferred its
interest in the Minto claims to Teck Corp.

In 1993, MintoEx was formed. Asarco and Teck sold their interest in the Minto claims (and leases) for shares in
MintoEx and provided $375,000 in working capital. Asarco and Teck also received a net smelter royalty of 1.5% to be
divided evenly. In that same year, Falconbridge, the parent of United Keno Hill, sold its interest in the DEF claims to
MintoEx for $1M, with payment being due in 1996. Falconbridge was granted an option to repurchase the DEF claims
on January 1, 2005 if the deposit was not in production by then.

An initial public offering of shares of MintoEx completed in 1994. There were 5,912,501 shares issued and outstanding
with Asarco being the majority shareholder with 3,297,500 shares (55.8%).

In 1995, a feasibility study was completed. Reserves were 8,818,000T of 1.73% Cu, 0.014 oz/t Au and 0.22 oz/t Ag at
0.5% Cu cut-off grade. Recoveries were 95% for Cu and 85% for Au and Ag. Mine life was projected to be 12 years at
a production rate of 477,000 tonnes per year.

In 1996, funding was arranged with Asarco to bring the deposit into production whereby Asarco would provide up to
$25M. Under the funding arrangement, Asarco would acquire a 70% interest in the project, MintoEx would retain a
30% interest and remain as operator. That same year, MintoEx made the $1M payment to Falconbridge for the DEF
claims completing the consolidation of the Minto and DEF claims. Also in that year, a 16 km access road was
constructed including a barge landing site on the West side of the Yukon River and a bridge over Big Creek. A further

- 38 -

12.8 km of road construction in 1997 was done to complete the new access road. Also in 1997, a co-operation
agreement was signed with the SFN. In 1999, a production license was received.

In 2001, most of the Asarco core and all of the Falconbridge core was destroyed by time and forest fire. A limited
amount of the old Asarco core that could be recovered was re-sampled in 2002. In June 2005, Sherwood Copper Corp.
acquired the Minto property. In 2006, mill construction commenced. A C$85 M debt package was arranged, forward
sales completed, and concentrate off-take agreement executed in October 2006. In 2007, a Power Purchase
Agreement for Minto was signed. That same year, a resource estimate for the Area 2 deposit was completed and the
first copper-gold concentrates at Minto Mine were produced. First concentrates from the Minto Mine were delivered
to the Port of Skagway, Alaska in July 2007. The Minto Mine declared commercial production and the first Minto
concentrates shipped from Skagway in October 2007.

In 2008, Capstone and Sherwood announced a combination to create an intermediate copper producer with
Sherwood shareholders overwhelmingly approving the business combination. In connection with the closing of a
precious metal transaction, Silverstone provided an upfront payment of $37.5 M for payable gold and silver from
Minto. Capstone and Sherwood completed the business combination in November 2008.

In 2009, the high grade Minto North Deposit was discovered and defined. Increased copper-gold mineral resources at
Minto were announced in June 2009. Also in 2009 there was a drill discovery of the Minto East prospect.

In 2010, the high grade Minto East Deposit was defined. Increased copper-gold mineral resources for Area 2/118 and
Ridgetop plus a preliminary mineral resource for Minto East was completed and announced in August 2010. The
Minto East mineral resource was further updated later in the year. There were further drill discoveries in 2010 at the
Wildfire and Inferno prospects.

In 2011, the Copper Keel and Wildfire areas were further drill delineated and incorporated into a larger deposit called
Minto South or MSD for short. A new mineral resource for the combined MSD deposit was announced in May of 2011
and the resource estimate was updated again later in the year and subsequently announced in February of 2012. Also
in 2011 there was a drill discovery of the Fireweed prospect.

In 2012, the Fireweed extension of the Minto East deposit was discovered and partially defined; the Inferno North
extension of the Minto North deposit was also discovered. New mineral resource estimates for the Fireweed and
Inferno North extensions were announced in October 2012.

No exploration was conducted on the mine property in 2013.

Geological Setting

The Minto Mine is found in the North-Northwest trending Carmacks Copper Belt along the eastern margin of the
Yukon-Tanana Composite Terrain. The Belt is host to several intrusion-related Cu-Au mineralized hydrothermal
systems. The Minto Property and surrounding area are underlain by plutonic rocks of the Granite Mountain Batholith
(the “Batholith”) of the Early Mesozoic Age. The component of the Batholith represented on the Minto Property is the
Minto pluton and is predominantly of granodiorite composition. Hypogene copper sulphide mineralization at Minto is
hosted wholly within this pluton in sub-horizontal horizons of structurally prepared rock.

For ease of reference the Minto copper-gold-silver system is divided into seven mineralized areas within the Minto
deposit; from North to South they are: Minto North; Inferno North; Minto Main; Minto East; Fireweed; Minto South
(MSD-a consolidation of Area 2, Copper Keel, Area 118 and Wildfire deposits that are now considered one continuous
deposit); and Ridgetop. Each of these deposits closely share a similar style of mineralization hosted by vertically
stacked, shallow dipping deformation zones within the intrusion. Remnants of the Main deposit are currently exposed
in an exhausted open pit mine and this geometry has been confirmed, a similar geometry is also exposed in the
currently operating Area 2 open pit. The other deposits have drill-delineated mineral resources and/or reserves but
mineralization is not exposed at the surface. These deposits and other mineral prospects define a general north-
northwest trend informally called the Priority Exploration Corridor.

Copper sulphide mineralization is found in the rocks that have a structurally imposed fabric, ranging from a weak
foliation through to a strongly developed gneissic banding. The contact relationship between the foliated deformation

- 39 -

zones and the massive phases of granodiorite is generally very sharp. These contacts do not exhibit chilled margins
and are considered by MintoEx geologists to be structural in nature, separating the variably strained equivalents of the
same or similar rock type.

The more highly strained deformation zones form sub-horizontal horizons and can be traced laterally for more than
1,000 m in the drill core. They are often stacked in parallel to sub-parallel sequences and it is postulated that the
foliated granodiorite horizons represent healed, shallowly dipping shear zones within the Batholith; theorized to have
formed when the rocks passed through the brittle/ductile transformation zone in the earth’s crust in transition from a
deep emplacement environment of the Batholith to eventual exhumation. There is on-going debate, however,
regarding the stratigraphic, intrusive, or structural nature of the zones hosting the foliation and mineralization.
MintoEx have engaged the Mineral Deposits Research Unit (“MDRU”) of the University of British Columbia to help
understand the mineral paragenesis and deformation history. No other recognized deposit type compares directly
with Minto mineralization. While an Iron Oxide Copper Gold (“IOCG”) style for the Minto Deposit cannot be
unequivocally demonstrated, the authors are of the opinion that this style of deposit provides the most consistent
model for the current level of understanding.

The primary hypogene sulphide mineralization consists of chalcopyrite, bornite, euhedral chalcocite, and minor pyrite.
Metallurgical testing also indicates the presence of covellite, although this sulphide species has never been positively
logged macroscopically.

Texturally, sulphide minerals predominantly occur as disseminations and foliaform stringers along foliation planes in
the deformed granodiorite (i.e. sulphide stringers tend to follow the foliation planes). Occasionally, coarse free gold is
observed associated with chloritic or epidote lined fractures that cross-cut the sulphide mineralization. The free gold
may be due to secondary enrichment during a later hydrothermal process overprinting the main copper sulphide-gold
event. Sulphide mineralization is always accompanied by variable amounts of magnetite mineralization and biotite
alteration. While these minerals occur in the non-deformed rocks they are present in the mineralized horizons in a
much greater abundance in the range of an order of magnitude greater than background.

Supergene mineralization occurs proximal to near-surface extension of the primary mineralization and beneath the
Cretaceous conglomerate. Chalcocite is the prime mineral in these horizons along with secondary malachite, minor
azurite and minor native copper. Observations of foliated and even copper mineralized cobbles in drilling indicate
that “Minto-type” mineralization was exposed, eroded and reincorporated in conglomerate sedimentary deposits by
the Cretaceous Age. Other rock types, albeit volumetrically insignificant, include thin dykes (typically less than 1 m) of
simple quartz-feldspar pegmatite, aplite, and an aphanitic textured intermediate composition rock.

Structural deformation includes the ore-bearing deformation zones, as well as folding present on the regional to
micro-scale. Within the deformation zones the foliation exhibits highly variable orientations with the presence of
small-scale (several centimetres in amplitude) folds. The ore-bearing zones are also occasionally folded on a scale of
several hundred metres. The larger-scale folds appear to be gentle folds with North-South axial traces. Late brittle
fracturing and faulting is noted throughout the property area; some of these faults have displacements significant
enough to compartmentalize the deposits. For example, the Minto Creek fault bisects the Minto Main deposit,
dividing it into north and south areas. The fault is modelled as dipping steeply North-Northeast with an apparent left
lateral reverse displacement. The DEF fault defines the Northern end of the Main deposit. It strikes more or less East-
West and dips North-Northwest and cuts off the main zone mineralization. The boundary between the Area 2 and
Area 118 ore zones is an intermediate NE dipping fault, and at least two parallel structures displace mineralized
domains in Area 118. A similar NW striking fault zone appears to define the North-Eastern boundary of the Ridgetop
deposit to the South-Western boundary of the Minto South Deposit, and defines the outcrop of the Cretaceous
conglomerate.

Pervasive, strong potassic alteration occurs within the flat lying zones of mineralization, and is the predominant
alteration assemblage observed in all of the Minto deposits. The potassic alteration assemblage is characterized by
elevated biotite contents and minor secondary k-feldspar overgrowth on plagioclase relative to the more massive
textured country rock. Additional alteration includes the replacement of mafic minerals by secondary chlorite,
epidote, or sericite observed both in mineralized and waste rock interstitially or fracture/vein proximal, as well as

- 40 -

variable degrees of hematization of feldspars. Minor carbonate overprint is occasionally observed associated with
secondary biotite. Silicification is present but not pervasive in the Minto deposits.

Exploration

Mineral exploration on the Minto property has been conducted intermittently since 1971. Subsequent to the
discovery of the Minto Main deposit, which has been mined out, the adjacent southern half of the property has
undergone systematic brownfields exploration. Exploration on the northern half is more sporadic.

There are currently more than 1,240 drill holes within a roughly 16 square kilometre area. As such, following up on
open mineralized horizons in geological models, projecting mineralized horizons into areas of little or no drilling, and
drilling near historical drill hole intercepts were the principal exploration tools employed by MintoEx and its
geologists. Subsequent to Capstone’s predecessor, Sherwood Copper’s, acquisition of Minto Explorations Ltd. in June
2005, exploration from 2005 to 2012 has concentrated mostly on diamond drilling. However, an extensive historic soil
sample survey and some ground based and airborne geophysics have been conducted and are very useful in guiding
drilling activity.

The current exploration approach by MintoEx is the systematic evaluation of modern electrical (chargeability);
geophysical methods by commissioning various “proof-of-concept” surveys over known mineralization and then
expanding survey coverage outward into untested areas using these methods that are calibrated to known deposits.
An emphasis is placed on looking for signature analogs as opposed to being pedantic about precise measurements of
response. The predominant electrical geophysical methods used are Gradient Array Induced Potential (GAIP), Dipole-
Dipole Induced Potential, and Titan-24 DC Induced Potential. Drill targeting is predominantly based upon the
coincidence of an anomaly in one of the electrical (chargeability) methods with an anomaly in the 1993 total field
airborne magnetic survey (MAG).

Within the currently known extent of the Priority Exploration Corridor, future exploration programs will likely be more
reliant solely on electrical/chargeability methods as the near-surface potential and discrete magnetic bull’s-eyes have
largely been targeted. Magnetic data in areas located north of Minto North plus areas West and East respectively of
the PEC may still be useful as these regions are still relatively under explored.

The current highest priority exploration targets are based on the evaluation of geophysics, soil geochemistry, geologic
modelling, and diamond drilling. The targets identified as Ridgetop Southwest, Airstrip, MSD Gap, and the newly
discovered Fireweed prospect are all located within a 2 km by 2 km area, south of the DEF fault. MintoEx sees good
exploration potential in the area North of the DEF fault, as evidenced by the discovery of the high grade Minto North
deposit early in 2009, the Inferno prospect in late 2010, and the Inferno North deposit in 2012.

In 2009, several other historic bedrock copper occurrences discovered in the 1970’s North of the DEF fault were
relocated and confirmed. In addition various copper-in-soil geochemical anomalies, often coincident with magnetic
geophysical anomalies, occur throughout the property and many of them remain untested. However, further
understanding of the bedrock geology North of the DEF fault is required before many of these targets can be properly
assessed and placed in perspective. No exploration has been undertaken since 2012.

Mineralization

Texturally, sulphide minerals predominantly occur as disseminations and foliaform stringers along foliation planes in
the deformed granodiorite (i.e. sulphide stringers tend to follow the foliation planes). Occasionally, coarse free gold is
observed associated with chloritic or epidote lined fractures that crosscut the sulphide mineralization. The free gold
may be due to secondary enrichment during a later hydrothermal process overprinting the main copper sulphide-gold
event. Sulphide mineralization is always accompanied by variable amounts of magnetite mineralization and biotite
alteration. While these minerals occur in the non-deformed rocks they are present in the mineralized horizons in a
much greater abundance in the range of an order of magnitude greater than background.

- 41 -

Massive mineralization occurs locally over intervals exceeding 0.5 m in thickness and semi-massive mineralization over
several metres in thickness may occur. In these sulphide rich areas, textures often resemble those seen in magmatic
sulphide zones with sulphide mineralization interstitial to the rock forming silicate minerals. The higher grade portion
of the Minto Main deposits roughly corresponds to the bornite zone where locally concentrations of bornite up to 8%
by volume are seen. The precious metal grades are elevated in the bornite zone (very fine gold and electrum occur as
inclusions in bornite) and occurrences of coarse grained native gold are noted almost exclusively in bornite-rich
material. The chalcopyrite zone is characterized by the metallic mineral assemblage of chalcopyrite-pyrite +/- very
minor bornite and magnetite. Empirical observations indicate the highest concentrations of bornite are associated
with coarse grained, disseminated and stringer-style magnetite mineralization, up to 20% by volume locally.

The Minto North and Minto East Deposits exhibit a zoning from West to East. High-grade bornite-dominant
mineralization is observed in the West with lower grade chalcopyrite-dominant mineralization in the East. The bornite
zone is defined by the metallic mineral assemblage bornite-magnetite-chalcopyrite. Bornite mineralization occurs as
strong disseminations and foliaform stringers locally >10% to occasional semi-massive to massive lenses up to 2 m in
thickness.

Mineralization at the Area 2/118/Copper keel regions of the Minto South Deposit is distinct in that mineralization is
predominantly disseminated (plus occasional foliaform stringers) and the semi-massive to massive sulphide
mineralization is absent; as a whole the mineralization is more homogeneous and consistent as compared to Minto
North or Minto Main. The primary mineral assemblage includes chalcopyrite-bornite-magnetite with minor amounts
of pyrite. A crude zoning is present in that the higher grade northern half of the Minto South Deposit shows increased
bornite concentrations up to 8% locally.

Mineralization at both Ridgetop and the Wildfire region of Minto South are subdivided into the near surface horizons
that have been affected by supergene oxidation and the more typical primary sulphide mineralization of the deeper
zones. The lower zones are defined by a mineral assemblage of chalcopyrite-magnetite with minor amounts of pyrite.
Chalcopyrite is the dominant sulphide in the lower zones, and bornite is only observed in minor amounts. Texturally,
chalcopyrite occurs as disseminations and foliaform stringers, and is rarely observed as semi-massive to massive
bands. Magnetite is coarse grained, disseminated, stringer-style, and can occur in bands up to 0.3 m in thickness, up
to 20% volume locally.

Drilling

No exploration drilling was conducted at the property in 2013.

Under the direct supervision of MintoEx and Capstone staff geologists, MintoEx drilled a total of 29,539 m in 84 holes
on the Minto property at Inferno North, Fireweed, and other targets between January and May 2012 using the
contractor Driftwood Diamond Drilling Ltd. of Smithers, BC. Forty-five of the 2012 drill holes (16,223 m) were used in
the resource estimations discussed in the Minto Report, however 39 drill holes (13,316 m) completed in 2012 are
associated with other exploration targets and as such are not incorporated into the mineral resource estimates used in
the Minto Report. MintoEx drilled a total of 106,456 m in 376 vertical and 19 angled diamond drill holes at the Minto
South Deposit from February 28, 2006 to July 5, 2011. The size of the drill core is NQ and NTW. The median length of
the drill holes is 276 m (average 269.5 m); the shallowest hole was 78 m long and deepest hole was 693 m. All 395
drill holes were used in the Minto South Deposit resource estimation. Three angled and 25 vertical holes drilled by
ASARCO in 1971 to 1974 were included in the Minto South Deposit resource estimate. Drill hole collars are spaced at
approximately 28 m to 60 m at the Area 2 resource sub-domain, 40 m at the Area 118 resource sub-domain, and 40 m
to 60 m centers at the Wildfire and Copper Keel sub-domains.

At Ridgetop, MintoEx drilled a total of 16,850 m in 139 vertical drill holes and three angled diamond drill holes from
May 2007 to September 2009. The size of the MintoEx drill core is NQ. The median length of the Ridgetop drill holes
is 120.5 m (average 122.5 m); the shallowest hole was 54 m long and the deepest hole was 322 m. One vertical hole
(150 m) and three angled holes (492 m) drilled by ASARCO in 1971, and four vertical (635 m) holes and four angled
holes (571 m) drilled in 1972 were included in the resource. The size of the ASARCO drill core is assumed to be BQ. In
1994, four vertical holes (520 m) and five angled holes (654 m) of HQ-sized core were drilled; these holes were used in
the resource estimate. Drill hole collars are spaced at approximately 20 to 60 m centers. Mineralized zones are
dipping moderately to the northeast.

- 42 -

At Minto North, MintoEx drilled a total of 11,548 m in 71 vertical and 17 angled diamond drill holes from January to
October 2009. In total, 87 drill holes are included in the resource model; one drill hole is excluded because it is
located well outside the currently defined deposit boundaries. No historical drill holes are included in the resource
model. The size of the MintoEx drill core is NQ. The median length of the 2009 Minto North drill holes is 120 m
(average 130 m); the shallowest hole was 57 m and the deepest hole was 342 m. Drill hole collars are spaced at
approximately 15 to 20 m centers. Mineralized zones are shallowly dipping to the northwest.

At Minto East, MintoEx drilled a total of 11,067 m in 13 vertical and 20 angled diamond drill holes from April 2007 to
August 2010. In total, 33 drill holes are included in the resource model. No historical drill holes are included in the
resource model. The size of the MintoEx drill core is NQ with the exception of four drill holes in NTW. The median
length of the Minto East drill holes is 332 m (average 336 m); the shallowest hole was 179 m and the deepest hole was
408 m. Drill hole collars are spaced at approximately 40 m centers. Mineralized zones are shallowly dipping to the
northwest.

Prior to 2008, all drilling for MintoEx was completed using the imperial system, and footages were converted to
metres by MintoEx personnel who logged and recorded all data in metres. Since 2008, drilling for MintoEx was
completed using the metric system. Drill hole collar locations were initially located using a differential GPS unit, and
more precise location coordinates were surveyed after completion of drilling by the Minto Mine survey team using a
Trimble R8 GPS unit.

Bulk density measurements were taken from nearly all holes drilled from 2005 through 2012 in both mineralized and
waste material. Measurements were taken at approximately every 1 to 3 m intervals in ore, corresponding to 1 to 3
measurements per run in strongly mineralized material, 1 every 5 m in poorly mineralized material, and at least 1
measurement every 20 to 30 m in waste.

Pieces of core were weighed both in air and in water using an Ohaus triple beam balance. Spot checks on the field
data were undertaken internally by MintoEx, where 159 samples from 66 drill holes were analyzed. Measurements
were recorded on a triple beam scale on the same piece of core that was originally measured.

Bulk density data obtained prior to 2005 were not used in the resource estimations because the data was constructed
by correlating bulk density to copper grade based upon too few actual measurements and because the core upon
which this method was constructed was destroyed in forest fires and the methodology could not be audited.

Sampling and Analysis

From 1973 to 2001, most of the samples sent for analysis were obtained by splitting the core using a mechanical
wheel core splitter (in contrast to a diamond saw from 2005 to 2010). In the case of two holes drilled in 1993 for
metallurgical grinding testing, the entire core through the mineralized interval was utilized to improve the validity and
reliability of the metallurgical tests and hence no assay data are available.

In 2005 and 2006, the mineralized intervals intersected in core were sampled in lengths ranging from 0.3 m to 3.0 m
and averaging 1.0 m to 1.5 m. The sampling intervals were typically 1.5 m in mineralized material and 3.0 m in longer
waste intervals within the mineralized zones. Two shoulder samples were taken in waste at both the upper and lower
contacts, consisting of a 1.5 m sample and a 1.0 m sample. Samples did not cross geological contacts. This approach
is appropriate for this style of mineralization and the objectives of the program.

In 2007, the mineralized intervals in core were sampled in lengths ranging from 0.24 m to 3.49 m and averaging
1.33 m with a median of 1.5 m from 7,450 sawn core samples. In 2008, the mineralized intervals in core were sampled
in lengths ranging from 0.25 m to 4.20 m and averaging 1.29 m with a median of 1.3 m from 12,538 sawn core
samples. In 2009, the mineralized intervals in core were sampled in lengths ranging from 0.19 m to 4.50 m and
averaging 1.47 m with a median of 1.5 m from 13,026 sawn core samples. In 2010, the mineralized intervals in core
were sampled in lengths ranging from 0.22 m to 3.90 m and averaging 1.41 m with a median of 1.5 m from 18,739
sawn core samples.

From 2007 through 2012, sampling intervals were typically 1.5 m to 2.0 m in mineralized material, and 3.0 m in longer
waste intervals between mineralized zones. Drill core assay samples were collected from all foliated granodiorite

- 43 -

horizons and, typically, sampling extended into the surrounding massive, unfoliated and unmineralized rock for at
least 3.0 metres. Individual samples do not cross the geological boundary between foliated and unfoliated rock which
is generally a sharp contact. The sampling methodology is appropriate for this style of mineralization.

During 2005 and 2006, drill core samples, Standard Reference Materials (“SRM”) and blanks were submitted to the
Vancouver Chemex laboratory for copper and gold analysis in North Vancouver, British Columbia. In addition, Chemex
was also instructed to perform analysis on pulp duplicates injected into the sample stream at regular intervals. In
2005, all samples were processed in Vancouver. In 2006, some samples were processed at other Chemex locations.
Chemex-Elko, Nevada processed 9% of the total number of samples and Chemex-Thunder Bay, Ontario processed
11%. The samples submitted to Chemex were first crushed in a jaw crusher to reduce the material to greater than
70% - 10 mesh (2 mm). A 100 to 250 g subsample was then split and pulverized to better than 85% passing - 75 μm.
Copper was determined through a four acid digestion method (HF, HNO3, HCLO4 digestion and HCL leach) with final
copper determination by atomic absorption spectroscopy (“AAS”). Non-sulphide copper was analyzed using sulphuric
acid leach with AAS determination. Gold was determined by one assay-tonne fire assay analysis. During 2005, all
sample analysis was completed by gravimetric finish. During 2006, the first 17% (1,955) of the sample analysis was
completed by gravimetric finish. For the remaining samples (9,182), the gold analysis was determined using AAS
method. Silver was analyzed using aqua regia digestion and AAS finish.

The 2007 drill core samples, blanks, SRMs and duplicates were submitted to the Vancouver Chemex laboratory for
copper and gold analysis in North Vancouver. Some samples were processed at other locations. SGS Laboratories
under agreement with MintoEx processed 485 samples (6% of the total number of samples); assays were all
performed at the Vancouver Chemex Lab. Sample preparations were performed at Chemex at Elko, Nevada, 4% of the
total number of samples, Chemex at Reno, Nevada 10%, and Chemex at Terrace, British Columbia, 50%. The samples
submitted to Chemex were first crushed in a jaw crusher to reduce the material to greater than 70% - 10 mesh (2
mm). A 100 to 250 g subsample was then split and pulverized to better than 85% passing - 75 μm. Copper was
determined by the four acid digestion method (HF, HNO3, HCLO4 digestion and HCL-leach) with final copper
determination by AAS. Non-sulphide copper was analyzed using sulphuric acid leach with AAS determination. Gold
was analyzed by one assay-tonne fire assay followed by AAS. Silver was analyzed using aqua regia digestion and AAS
finish.

Two laboratories were used in 2008. Drill core samples, blanks, SRMs and duplicates were submitted to
SGS Laboratories under agreement with MintoEx, and to the Vancouver Chemex laboratory for copper and gold
analysis in North Vancouver after processing at the sample preparation facility in Terrace. SGS Laboratories under
agreement with MintoEx processed 61% of the total number of samples from areas outside of Ridgetop. The
remaining 39% of the samples were analysed at the Vancouver Chemex Lab. The samples submitted to SGS were first
crushed in a jaw crusher to reduce the material to greater than 85% - 10 mesh (2 mm). A 250 g subsample was then
split and pulverized to better than 90% passing - 75 μm. The pulp was split with one part analysed for copper and
silver at the SGS facility at the Minto site and one part analysed for gold and non-sulphide copper at SGS Red Lake,
Ontario operation. During mid-July, silver analyses were performed by SGS at Lakefield, Ontario and Don Mills,
Ontario after a switch failure in SGS Minto ICP-AAS equipment. Copper reanalysis due to SRM failures were done by
SGS at Lakefield and Don Mills in Ontario. Copper was determined by aqua regia digestion method with final copper
determination by atomic absorption spectroscopy (“AAS”). Non-sulphide copper was analyzed using sulphuric acid
leach with AAS determination. Samples were assayed for gold using a fire assay procedure on a thirty grams sub-
sample with atomic absorption spectroscopy finish. Silver was analyzed using aqua regia digestion and AAS finish.

The samples submitted to Chemex from July 27 to August 19 were first crushed in a jaw crusher to reduce the material
to greater than 85% - 10 mesh (2 mm). A 250 g subsample was then split and pulverized to better than 90% passing -
75 μm. The sample turnaround time increased to nearly seven weeks after implementing the finer crush, so
subsequent samples were first crushed in a jaw crusher to reduce the material to greater than 70% - 10 mesh (2 mm)
with a 250 g subsample split and pulverized to better than 85% passing - 75 μm. At Chemex, copper was determined
by the four acid digestion method (HF, HNO3, HCLO4 digestion and HCL-leach) with final copper determination by
AAS. Non-sulphide copper was analyzed using sulphuric acid leach with AAS determination. Gold was determined by
one assay-tonne fire assay analysis followed by AAS. Silver was analyzed using aqua regia digestion and AAS finish.

The 2009 and 2012 drill core samples, blanks and SRMs were submitted to the Vancouver Chemex laboratory for
copper and gold analysis in North Vancouver. In addition, Chemex was also instructed to perform analysis on pulp and
coarse reject duplicates injected into the sample stream at regular intervals. After August 2010, the pulp and coarse
reject duplicates were returned to the MintoEx office in Vancouver, where they are transferred to fresh Kraft paper
bags, assigned new sample numbers and resubmitted to Chemex as “blind duplicates”. The samples submitted to
Chemex were first crushed in a jaw crusher to reduce the material to greater than 70% - 10 mesh (2 mm) with a 250 g
subsample split and pulverized to better than 85% passing - 75 μm. Copper was determined by aqua regia digestion
method with final copper determination by AAS. Non-sulphide copper was analyzed using sulphuric acid leach with
AAS determination. Gold was determined using a fire assay procedure on a thirty grams subsample with atomic
absorption spectroscopy finish. Silver was analyzed using aqua regia digestion and AAS finish.

Of the 79 drill holes in the 2006 Area 2 database, 11 collars (13%) were selected at random in the area of the resource
estimation boundaries and were checked by a handheld Garmin GPS. The recorded values show good agreement and
differences lie within the error of the handheld GPS. In December 2008, MintoEx conducted a review of the drilling
data from Area 2/118 and Ridgetop deposits. A total of 10% of the values in the database were checked against
primary sources including the borehole collar surveys against survey records, lithology and mineralization data against
core logs and assays for copper and gold against signed certificates of analysis. No significant errors were found. In
November of 2009, Kirkham Geosystems manually compared the Minto North Deposit database assays against
original assay certificates. A total of 15% of the values were checked and no errors or omissions were found. In
addition, a spreadsheet check was run against the Area 2, Area 118 and Ridgetop database.

Security of Samples

Exploration work by MintoEx was conducted using a quality assurance and quality control program generally meeting
industry best practices. All aspects of the exploration data acquisition and management including surveying, drilling,
sampling, sample security, and assaying and database management were conducted under the supervision of
appropriately qualified geologists and include written field procedures and verifications.

Analytical control measures typically involve internal and external laboratory control measures to monitor the
precision and accuracy of the sampling, preparation and assaying. Insertion of certified SRM and blank material
monitors the reliability of assaying results and is also important to prevent sample mix-up and monitor potential
contamination of samples.

Assaying protocols typically involve regular duplicate and replicate assays to monitor the reliability of assaying results
throughout the sampling and assaying process. Umpire assaying is typically performed as an additional reliability test
of assaying results by re-assaying a set number of sample rejects and pulps at a secondary laboratory.

ALS-Chemex and SGS implemented internal laboratory measures consisting of inserting quality control samples (blanks
and certified reference materials and duplicate pulp) within each batch of samples submitted for assaying.

Quality control procedures used during the 1971 to 2001 drill programs are not known, with the exception of 10
samples submitted for umpire analysis in 1994. The 2001 sample shipments were accompanied by four types of
quality control samples, namely: a blank (granodiorite from the site), an ASARCO coarse standard, prepared pulp
samples and duplicate splits (coarse ground rejects and the pulverized rejects).

MintoEx inserted one each of an SRM, blank, pulp reject duplicate and coarse reject duplicate (for Chemex only) with
every 16 sawn core samples. Umpire assaying of pulps at a secondary laboratory was conducted periodically, typically
involving analysis of 0.5% or more of the sawn core samples.

Mineral Resource and Mineral Reserve Estimates

A primary objective of the Minto Report was to produce a mineral reserve evaluation for the Area 2 Open Pit and Area
118 underground within the Minto South Deposit. Area 2/118 and the exploration areas Copper Keel/Wildfire are
considered continuous and a new combined mineral resource estimate was reported on May 30, 2011, which is
known as Minto South Deposit (“MSD”). The MSD estimate was reviewed and approved by SRK. The Minto North and
East deposits have been evaluated by Kirkham Geosystems Ltd. Subsequent to the Minto Phase VI Report additional

- 45 -

drilling was conducted in the Fireweed extension of the Minto East Deposit and Inferno North extension of the Minto
North Deposit.

Kirkham Geosystems Ltd. has conducted further resource modelling and mineral resource estimation based upon this
new drill information. Mineral resource estimations for Fireweed and Inferno North were completed by Kirkham
Geosystems Ltd. and reported on October 25, 2012.

The mineral resource estimates for the MSD and Ridgetop deposits were completed by Dr. Wayne Barnett, Ph.D.,
Pr.Sci.Nat., an independent Qualified Person as defined by NI 43-101. The effective date of the revised MSD resource
estimate is September 13, 2011; the effective date of the Ridgetop resource estimate is August 30, 2010. Marek
Nowak, P.Eng., analyzed the data, reviewed and validated the mineral resource estimates for Minto South and
Ridgetop. The Minto North, Minto East, Fireweed and Inferno North resource estimates were completed by
Garth Kirkham, P.Geo., of Kirkham Geosystems Ltd., an independent Qualified Person as defined by NI 43-101. The
effective date of the Minto North resource estimate is December 1, 2009; the effective date of the Minto East
resource estimate is October, 2010; the effective date of the Fireweed and Inferno North resource estimates is
October 25, 2012.

Minto used the mineral resource estimates completed by the Qualified Persons mentioned above and completed a
reconciliation procedure to remove mineral resources which had been extracted during 2013 operations. The results
of the reconciliation for mineral resources at a 0.5% Cu cut-off grade (“COG”) are presented below.

In order to demonstrate a reasonable prospect of economic extraction, SRK evaluated the overall mineral resource
against an economic shell created using Whittle™ pit optimization software. SRK regards the entire reported resource
as having reasonable prospects of economic extraction.

The mineral reserve estimate for open pit and underground mineralization is summarized in the table below. During
2013, mining of the MSD deposit continued in the Area 2 Open Pit. Since the stockpiles contained material from the
Main Zone and the MSD deposits, for clarity, they have now been classified as a separate entity.

The mineral reserve estimate for open pit and underground mineralization is summarized in the table above. During
2013, mining of the MSD deposit continued in the Area 2 Open Pit. Underground exploration drifting was conducted
on the 740 Level of the Area 118 underground to denote the extents of the mineralized zone. The open pit operations

- 47 -

in the Area 2 Pit and underground exploration drifts resulted in mineral reserve depletion. The stockpile inventory
increased due to open pit mining activities in the Area 2 Pit. During the fourth quarter of 2013, daily ore production
exceeded the daily mill demands as mineral extraction in Area 2 entered thicker ore horizons. An engineering change
also occurred due to the removal of mineral reserves in Ridgetop. A write down on the Ridgetop asset occurred in the
fourth quarter; citing potentially lower metallurgical recoveries due to higher than anticipated soluble copper content
than previously anticipated resulted in Ridgetop being sub economic. However Minto will continue to conduct further
metallurgical studies on Ridgetop.

Reconciliation

Reconciliation activities were conducted for the Area 2 Pit, Area 118 Underground and mine reported to mill reported
production.

Area 2 Pit reconciliation compared the mine production model to the block model. The results indicate that:

•

Sulfide production had a nominal variance in terms of tonnage. Reported sulfide copper grade was slightly
lower than predicted in the block model; and

• Overall, the production model reported less tonnage (6%) and lower grade (2%) than predicted in the block

model.

The reason for these differences is considered to be the natural conditional bias in the long range resource model.
The resource model tends to underestimate the sulfide ore in the higher grade portion of the deposit and to over-
estimate the sulfide ore in the lower grade periphery of the deposit.

Underground exploration drifting was conducted on 740 Level to denote the extents of the mineralized zone for Area
118. Minimal amount of ore was extracted. Overall, there was a nominal variance in terms of tonnage when
compared to the resource block model. The reported copper grade was higher than predicted by the block model
(actual grade is a weight composite based on grab samples from blasted ore rounds). The primary reasons for the
grade difference are likely due to the sampling procedure that tends to show a bias toward higher grades and to the
interpreted ore / waste contact is slightly off-alignment with actual mapping. Further investigation is being conducted
to enhance underground grade control processes.

The stockpile inventory increased due to the open pit mining activities in the Area 2 Pit. During the fourth quarter of
2013, daily ore production exceeded the daily mill demands as mineral extraction entered the lower levels of the Area
2 pit where thicker ore horizons exist.

The mine to mill reconciliation compares the estimated mill throughput by the mining operations and the actual mill
throughput reported by the Minto metallurgy group. The reconciled throughput for 2013 reported higher tonnes than
estimated by the mine but the comparison is within a 5% variance.

Mining Operations

The Minto Mine commenced operation in 2007 and since that time has maintained continuous production and has
shown continual improvement. Since the start of operations, the mill has undergone numerous upgrades and
expansions. Mining utilizes both open pit and underground techniques. The process plant produces copper
concentrate containing silver and gold by-products which is trucked to Skagway.

In 2013, open pit mining activities were primarily focused on mineral extraction of the Area 2 Stage 2 Pit which will
conclude in early 2014. Surface deposits will continue to be developed as open pit that will rely on a contractor mining
approach. Underground mining activities in the first half of the year focused on the main ramp development along
with infrastructure requirements. The fresh air raise initial development was completed in October and full operation
of the raise will be completed in early 2014. Access to the 740 Level was completed and production commenced on
the 740 Level in September. The ramp continued to the 710 elevation until year end.

During 2013, the mill processed a feed of 1,402,264 tonnes at a copper grade of 1.31%, a silver grade of 4.59 g/t and a
gold grade of 0.52 g/t. The average production rate was approximately 3,842 tpd. The mine produced a total of
46,303 tonnes of copper concentrate at an average copper grade of 36.5%.

MintoEx sold most of its gold and all of its silver production to Silverstone Resources in November 2008. Silverstone
was subsequently bought by Silver Wheaton who now owns the Minto Mine precious metal stream. Silver Wheaton
pays Minto $300/oz Au and $3.90/oz Ag through the mine life.

The environmental and socio-economic assessment and review process is underway for the Phase V and Phase VI
expansions. At this stage of the assessment there have not been any conditions expected to be of significant concern,
or that cannot be mitigated. Engagement with regulators and other stakeholders has been ongoing to minimize
potential delays in the assessment review. Once the project has been assessed it will continue into the licencing
phase.

Federal and Provincial tax calculations for the Minto Mine start with the before-tax cash flow amounts from the cash
flow portion of the model and essentially deducts the cost of building and developing the mine and mill (Class 41a un-
depreciated capital costs (“UCC”), Canadian exploration expenses (“CEE”) and Canadian development expense (“CDE”)
as would be expected over the life of the mine and as allowed by the Canadian tax rules. Generally Class 41a UCC and
CEE can be deducted 100% against profit from the mine while CDE can only be deducted on a declining balance basis
at 30% per year. The losses that are generated in the first few years of mine operation are deducted against income in
later years.

The Yukon QMA Royalty also starts with before tax cash flow from the cash flow portion of the model and deducts
depreciation at 15% per year on a straight-line basis for the mine capital assets and mill capital assets. It deducts
deferred pre-operating costs that are not capital assets on a unit of production method. The Yukon QMA Royalty does
not have a loss carryover or carry back provision. Taxes are paid at rates that increase as income increases to a
maximum of 12%.

Exploration and Development

No exploration activities are slated at Minto for 2014.

The Area 2 Stage 2 pit was completed in early 2014, following which surface mining has moved to the Area 118 pit
which will finish in mid-August. The mine plan calls for reduced surface mining rate during the first half of the year to
balance mining and milling activities.

Capstone is able to defer the development and production from the Area 118 underground for one year without a
negative impact on 2014 production. The underground plan in 2014 will target the M-Zone; a high grade mineralized
horizon located adjacent to the Area 2 Stage 2 Pit. Upon completion of the M-Zone, the Area 2 Stage 2 Pit will be
utilized for water storage.

The mill will process ore from the Area 2 and Area 118 pits, supplemented with ore from underground and stockpile
for the first half of the year. Stockpiled ore will be the primary source in the second half of the year. Mill throughput
in 2014 will remain relatively constant throughout the year, however grades will decline starting in August when lower
grade material from the stockpile is scheduled to be milled.

Pre-stripping of Minto North is set to begin on August 2014, contingent upon receipt of the necessary permits and
licenses. A delay in the Phase V/VI permit application has resulted in the shift of the most significant production from
Minto North by one year.

Santo Domingo Project (Chile)

The Santo Domingo Project is the subject of a report titled “Technical Report on the Santo Domingo Project, Chile”
dated September 28, 2011 (the “Santo Domingo Report”). This technical report was prepared by Ausenco Minerals
Canada Inc. The Santo Domingo Report was written by: David Brimage, AusIMM CP, David W. Rennie, P.Eng.,
John Nilsson, P.Eng., Art Winckers, P.Eng. and Michael Davies, P.Eng., each a Qualified Person as defined in NI 43-101.
The following descriptions of the Santo Domingo Project are based on assumptions, qualifications and procedures
which are set out in the Santo Domingo Report. Reference should be made to the full text of this report which is
available in its entirety on SEDAR at www.sedar.com under the Company’s profile.

Project Description and Location

The Santo Domingo Project is based on a large open pit copper/gold/magnetite resource located approximately two
hours north of Copiapó by paved road and 5 km southeast of the town of Diego de Almagro in Region III of Northern
Chile. The Santo Domingo property was originally part of the BHP Candelaria project area, which consisted of eight
non-contiguous concessions in a north-south corridor extending between the towns of Taltal to the North and to a
point about 75 km South of the city of Copiapó.

The Santo Domingo Project area encompasses 82 contiguous mining concessions covering an area of 19,841 hectares
in Region III of Northern Chile. The centre of the deposit is located at approximately 26°28'00”S and 70°00'30”W.

The project was owned by Far West, which was formerly a TSX listed mineral exploration company headquartered in
Vancouver. On June 17, 2011, Far West was acquired by Capstone at the same time as the Company entered into a
strategic relationship with Korea Resources Corporation (“KORES”). The terms of this relationship provided for
amongst other things, a private placement in the equity of the Company, representation on the Board of Directors of
the Company, the acquisition of a 30% interest in the project by KORES, participation in the financing of the project as
well as an agreement to enter into a life of mine off-take agreement for 50% of the production of the project on
prevailing market terms.

The initial Candelaria Project land package assembled by BHP in 2002 consisted of 3,434.5 km2 of exploration
concessions. In 2002 and 2003, Far West and BHP entered into Project Area Agreements that allowed Far West to
earn an interest in the concessions within the project area. Effective August 5, 2003, Far West assigned interests in
the Project Area Agreements to its wholly owned Chilean subsidiary, Minera Lejano Oeste S.A. (“MLO”). On
May 4, 2005, BHP terminated any interest in the concessions within the project area and commenced transfer of title
of all these concessions to MLO in exchange for a retained 2% NSR royalty. As of the date of the Santo Domingo
Report, all concessions in the Candelaria Project area are 100% owned by MLO.

Far West, now a subsidiary of Capstone, controls 100% of 82 exploitation concessions (“constituidas”) in the
Santo Domingo area, including the exploitation concessions acquired through option (Estrellita 1/10, Iris I 1/200, Iris II
1/160, Iris 1/55, Estefánia, Manto Ruso 1/8, Pichanga 1/100, and Santo 1/20.) In all, the 82 exploitation concessions
cover a total area of 19,841 ha.

Accessibility, Climate, Local Resources, Infrastructure and Physiography

Access to the Santo Domingo property area is 1 kilometre off the paved highway C-17 from Diego de Almagro (5 km
to the North) to Copiapó (approximately 120 km to the South).

The Santo Domingo property is located in the Atacama Desert, one of the driest regions on earth. The climate is arid
and the weather is generally clear and warm in all seasons and poses no limitations on field activities. The closest
weather station where temperature and precipitation measurements have been recorded for some time is the city of
El Salvador. The daytime high and low temperatures there are 26°C and 0.8°C for July, and 30°C and 9.8°C for January,
respectively. The highest average recorded precipitation is in May at 14.8 mm and the lowest is in December at 0 mm.

The region has well-established infrastructure (power, water, transportation, work force, etc.) to service the mining
community. There is no infrastructure at Santo Domingo property itself other than gravel roads for access to the
property and drill sites. The project is approximately 1 km from a paved highway and 5 km from a sub-station that
provides power to the town of Diego de Almagro.

Several cities or towns are near the Santo Domingo property. Diego de Almagro, located adjacent to the property, has
a population of several thousand people. Chañaral is a deepsea port less than one hour’s drive to the west of the
property. It has a population of approximately 10,000 people, hotel accommodations, food, fuel, and minor services.
The most important logistical centre in the region is Copiapó, approximately two hours’ drive to the south of the
Santo Domingo property. It has a population of approximately 150,000 people, an airport with daily scheduled flights
to Santiago and Antofagasta, and abundant businesses offering services specific to mining and exploration.

Vegetation is very sparse. In the valley bottoms, plant life consists of small, widely-spaced bushes a few tens of
centimeters in height. Hillsides and peaks are generally devoid of any vegetation. In spite of the dry conditions, hills

- 50 -

of gentle to moderate relief have been cut by deep gullies and flanked with gravel-filled valleys and alluvial fans;
evidence of water movement preserved since conditions were less arid. Elevations range from approximately 900 to
1,500 masl.

Seismic zone maps of South America indicate that the project area is likely to have high seismicity and the site is
considered part of Zone 3 (shores) according to the Chilean National Design Code Nch2369, with a peak ground
acceleration of 0.4 g.

History

Mining for copper, gold, and iron has been ongoing in this area since early in the 19th century. Small mines in the
region supplied copper ore to smelters in both Chañaral and Pan de Azúcar. Independent copper mines have been in
operation on what is now Anglo American’s Manto Verde deposit (located 25 km Southwest of the Santo Domingo
property) since the late 1800s, but significant production in this area started in 1906. Between 1906 and 1935, a
reported total of 400,000 tonnes grading in excess of 3% Cu was mined from the Manto Verde fault zone.

Previous ownership of concessions in the Santo Domingo property is unknown. The area appears to have had a
relatively long history of small-scale mining and prospecting. Mining activities on the nearby Manto Verde deposit
date back to the late 1800s and it is probable that workings in the Santo Domingo property have a similar age.

Many small inactive mines and a myriad of pits occur throughout the property area. The mines typically exploited
copper mineralization hosted in narrow (one meter to five meters) steeply-dipping veins and, in some cases adjacent
strata to these veins. The largest mines are located along approximately 700 m of the Santo Domingo structure.
These mines include La Estrella, La Estrellita, El Iris, and others. Judging by the size of the dumps and number of adits,
it is possible that this specific area produced upwards of 500,000 tonnes. A second area of minor production is a small
open pit with peripheral underground workings on the Caprichosa concession in Target Area 4a2 (Far West
nomenclature) that may have produced in the order of 20,000 tonnes of copper oxide-bearing coming from a
specularite stratum.

However, surface workings at the majority of the mines in the Santo Domingo property (other than those noted
above) are generally less than a few tens of metres in length and the extent of underground development is unknown.
Judging by the quantity of dump material adjacent to most of these mines, it is probable that production was no more
than a few thousand tonnes at any one site.

The initial Candelaria Project land package was assembled by BHP in 2002. In 2002 and 2003, Far West and BHP
entered into Project Area Agreements that allowed Far West to earn an interest in the concessions within the project
area. Effective August 5, 2003, Far West assigned interests in the Project Area Agreements to MLO. On May 4, 2005,
BHP terminated any interest in the concessions within the project area and commenced transfer of title of all these
concessions to MLO in exchange for a retained 2% NSR royalty.

No historic resource estimates or production records for workings in the Santo Domingo property have been located.

Geological Setting

The Santo Domingo deposit is located in the Chilean Iron Belt (“CIB”) to the east of the Atacama fault zone, a complex
sinistral strike-slip and dip-slip fault system that runs sub-parallel to the coast of Northern Chile for over 1,200 km.
The CIB contains a large number of copper and iron deposits of cretaceous age. The geology of the belt consists of
volcanic flows and tuffs, dioritic intrusives and calcareous sediments typical for a volcanic arc environment. The
geology of the Santo Domingo is dominated by andesitic volcanic flows and limestone horizons with occasional
outcrop of diorite intrusions. Large parts of the deposit are covered by younger cover consisting of clay and gravel.
The CIB is characterized by a large number of small surface showings of copper oxide, frequently accompanied by
specularite. The Santo Domingo deposit is essentially blind and is hosted by extensive tuff horizons that are overlain
by andesitic volcanics.

The Santo Domingo Project lies on the east side of the Atacama fault complex which, in this area, consists of
numerous clusters of generally north-south structural breaks in a belt approximately 30 km wide. It appears that the
10 km wide westernmost cluster, which hosts the Manto Verde copper deposit, is the main part of the fault system.

- 51 -

The bulk of the rock exposed in the Santo Domingo Project appears to overlie the Punta del Cobre volcano-
sedimentary sequence. It is an intercalated and interfingered sequence of volcaniclastics, andesite flows, limestone,
and calcareous sedimentary rocks, probably of the Lower Cretaceous Bandurrias and Chanarcillo Groups. The
Bandurrias Group is defined as a predominantly volcanic sequence of andesite flows and volcaniclastic rocks.
Chanarcillo Group rocks consist largely of limestone and calcareous marine sediments. Both definitions match
observed geology on the Santo Domingo Project.

Exploration

Exploration work in the Santo Domingo area was conducted by Far West from July 2003 to May 2010 and by Capstone
from August 2011 to May 2012. It consisted of:

•
•
•
•
•

•

50 km2 of geological mapping at 1:25,000.
50 surface rock samples for analysis for Au and a 27-element Inductively Coupled Plasma (ICP) suite.
47 sieved (106 micron) drainage sediment samples for analyses as above.
17.6 km of Induced Polarization (IP) survey.
A total of 120,168 m of drilling in 464 holes, including 90,611 m of reverse circulation (RC) drilling in 348 holes
and 29,557 m diamond (core) drilling in 114 holes.
Analysis for gold and 27-element ICP on two-metre intervals for RC and one-metre intervals for core.

A total of 50 rock chip samples were collected from the Santo Domingo area and sent to ALS Chemex Laboratories in
La Serena (ALS Chemex) for gold and 27-element ICP analyses. Samples with over 10 g Au and over 10,000 ppm Cu
were assayed and bubble plots of copper and gold values produced. Samples were generally taken where copper
oxides were apparent, and hence most samples contained anomalous levels of copper.

A total of 47 sediment samples were collected from drainages within and immediately peripheral to the
Santo Domingo area. The samples were analyzed by ALS Chemex for gold and a 27-element ICP package. Most
drainage channels in the area were sampled.

Approximately 200 g of -106 μm material was collected from each sample site using an Endecott No. 140 sieve (or
equivalent) and simple bubble plots of copper and gold in sediments were produced. Drainages in the areas underlain
by andesite flows, especially in the North and Northwest part of the target area, are generally anomalous, with copper
values typically in excess of 400 ppm. This broad anomaly is roughly coincident with the widespread distribution of
Northwest trending specularite-copper oxide mineralized veins that cut the andesites. The highest copper value in
drainage sediment (sample 7954) was 1,865 ppm from within the Santo Domingo area, approximately two kilometres
east-southeast of the Estrellita mine. No associated bedrock mineralization is known.

Mineralization

Copper-bearing IOCG-type mineralization is widespread in the Santo Domingo area. Specular hematite and copper
oxides (including chrysocolla, brochantite, and malachite) are the typical near-surface mineral assemblages. Copper
oxides typically persist to 70 m to 90 m below surface, with chalcopyrite being the dominant copper mineral at greater
depths.

Manto mineralization in tuffaceous or calcareous sediments is widespread on the property. In the Estrellita and
Estefania areas, several gently north-dipping, strata-bound iron oxide (specular hematite near surface, grading to
magnetite at depth) ± copper horizons, up to 12 m thick, occur in roughly the same 200 m stratigraphic interval, and
have been tentatively traced with drilling or extrapolated across 3 km of strike length. Mineralization typically occurs
within a simple single-phase breccia of fine-grained, calcareous tuffaceous sediment. The breccia matrix typically
consists of fine-grained specular hematite with disseminated, stringer and fracture-coating copper oxides, and rare
clots of chalcopyrite. Breccia horizons appear to be largely strata-bound, but to the south are discordant, following
the steeply-dipping Santo Domingo fault, suggesting that this fault may have been a fluid conduit.

In the SDS deposit, copper mineralization occurs in a sequence of iron oxide mantos within a tuffaceous package
between andesitic flows. Drilling has identified a 150 m to 500 m thick, mineralized sequence covering an area of

- 52 -

approximately 1,300 m by 800 m. Mineralization consists of stacked chalcopyrite-bearing specularite-magnetite
mantos, within tuff and tuffaceous sediments overlain by andesitic flows.

The Iris deposit is approximately 500 m wide, with a strike length of 1,600 m. The deposit consists of iron oxide
mantos and breccias along a North-Northwest-striking fault zone. Mineralization occurs close to surface at the
Southern end and plunges gently towards the North. The distribution of copper mineralization in the Iris deposit is
more erratic and irregular than in the SDS deposit, owing to the fact that structural control seems to have played a
greater role in the Iris deposit than in the more continuous stratiform replacement style mineralization at SDS. The
dominating iron oxide at Iris is hematite, while the main copper mineral is chalcopyrite. There are some old mine
workings at the southern end of the deposit where copper oxides such as brochantite and chrysocolla were mined at
surface. The mineralization is hosted by a specularite manto that is cut by steeply-dipping structures. The extent of
mineralization at surface is approximately 100 m by 60 m.

The Estrellita deposit is an East-West-striking, flat-lying to shallowly north-dipping tabular body lying approximately
3.5 km Northwest of SDS. The zone has been faulted into a series of four blocks which step downwards to the North,
with displacement across the faults ranging up to approximately 75 m. The overall footprint of the zone measures 900
m long by 450 m wide, and is up to 100 m thick. The zone is thickest in the middle and narrows somewhat towards
the periphery. There are narrower zones of limited lateral extent in the footwall of the main zone.

Mineralization at the Estrellita deposit is a mixture of manto-style iron oxide and structurally controlled vein style
mineralization. The central part of the Estrellita deposit consists of a more or less horizontal tabular body of iron
oxide manto that appears to have formed at the intersection of a horizontal and a steeply dipping set of specularite
structures.

Drilling

Drilling has been conducted in the Santo Domingo area since May 2004. Far West has completed 348 RC drill holes in
the target area for a total of 90,611 m and 50 diamond drill holes for a total of 16,275 m. As of May 31, 2010, drilling
in the Santo Domingo area totalled 106,886 m in 398 holes.

In late 2011 and early 2012, Capstone conducted an infill drilling campaign that was designed to elevate the projected
first three years of production from the indicated category to the measured category. A secondary purpose was to
collect material for metallurgical test work at the feasibility study level. The campaign consisted of 66 diamond drill
holes for a total of 13,282 m of additional drilling. A new mineral resource estimate incorporating the results of the
latest infill drilling campaign will be reported in the upcoming definitive feasibility study (“DFS”).

Drilling was contracted to Harris y Cia., Major Drilling, Geo Operaciones and Captagua, all based in Chile. Most of the
RC drilling was conducted by a truck-mounted Schramm Rotadrill, using a centre return hammer and a 5.5 in. (13.97
cm) carbide button bit. The diamond drilling was conducted by various types of equipment. HQ core (63.5 mm
diameter) was typically drilled to a depth of approximately 300 m, below which NQ core (47.6 mm diameter) was
drilled. Drilling was conducted in two 12-hour shifts per day. Samples, taken in two-metre intervals for RC, were
collected by drilling personnel, and tagged and organized by Far West personnel. A geologist was generally on site
during most of the day shift for RC drilling.

Diamond drill core was sampled in one-metre (all DD holes before 2010) or two-metre (DD holes 2010) intervals that
were marked by Far West geologists in order to adjust the samples to geological units.

Most holes are vertical as the orientation of mineralization at SDS and Estrellita is horizontal or gently dipping.
Inclined holes, particularly diamond holes, were drilled in order to establish the limits of mineralization at the edges of
the deposits as well as to establish the structural framework at Estrellita, Iris, and Iris Norte. Drill collars were located
using a differential GPS. Coordinates are accurate to within one metre or less. Relative elevations between holes in
close proximity (such as at SDS) were determined using a tight chain and clinometer.

Drill cuttings and core were logged using a set of codes similar to those used for surface mapping. All geological data
were entered digitally into summary logs. All digital data (analyses and geological logs) were subsequently entered
into an MS Access project database for presentation and section generation.

Drilling was originally designed to target gravity and magnetic anomalies for IOCG mineralization of Candelaria or
Manto Verde style. In April 2005, drillhole 22 intersected iron oxide mantos with copper mineralization of grade and
width that had the potential to be economic. Further drilling in the area outlined the SDS deposit. Subsequent drilling
to the northwest of SDS following a north-northwest trending gravity anomaly discovered and outlined the Iris deposit
with mineralization of similar style to SDS. Additional drilling in the northwestern part of the Santo Domingo area,
around the small-scale Estrellita mine workings, outlined the Estrellita deposit, which is more similar to Manto Verde
as it represents copper oxide mineralization along a fault zone. The 2008 drilling outlined a new zone of
mineralization known as Iris Norte. Additional holes have been drilled to test other gravity and magnetic features in
the Santo Domingo area and intersected widespread but discontinuous copper mineralization around the four
outlined deposits.

In the author of the Santo Domingo Report’s opinion, the drilling has been conducted in a manner consistent with
standard industry practices. The spacing and orientation of the holes are appropriate for the deposit geometry and
mineralization.

Sampling and Analysis

Reverse circulation drill cuttings were blown into a cyclone and collected every two metres from top to bottom of
each hole, regardless of lithology changes. This material was dumped directly into a riffle splitter with a bar
separation of approximately one centimetre. Both parts of the initial split were reintroduced to the splitter and
divided a second time to ensure adequate mixing of the entire sample. Half of this initial split was re-split and then
split again.

These three consecutive splits resulted in a final sample one-eighth the size of the initial complete sample. A 2 kg to
3 kg portion of this final split was bagged and ticketed with a unique assay number, ready to be sent to the laboratory
for analyses. A second sample of 3 kg to 4 kg was collected from the other half of the final split and stored (buried) at
or near the drill site. This complete second set of samples can be used for confirmation assays, petrographic work,
etc.

In the case of diamond drilling, core was placed into wooden core boxes by the drilling contractor at the drill. The
depth of each interval of core pulled was marked on a wooden block and placed in the core box. The core was then
transported to a logging facility by Far West personnel. At the logging facility, the core was photographed and a
geotechnical log completed. Geotechnical data recorded included recovery, rock quality designation (RQD), fracture
frequency, rock alteration and weathering, structure type, angle and roughness, joint compressive strength (JCS), and
bulk density. Cut core samples with a length of 15 cm or 20 cm were also collected and stored in preparation for
subsequent triaxial and point load tests.

The core was then geologically logged noting lithology, mineralogy, etc., using the same codes employed for logging of
the RC cuttings. Structural information was also noted during core logging, something that was not possible for RC
cuttings. Samples for assay were marked at one metre intervals by technicians, and subsequently adjusted by the
geologist to correspond to major lithologic contacts. Sample lengths were not less than 0.5 m, nor did they exceed
two metres. Sampled intervals were cut in half along the drill axis using a diamond saw. Half of the sample was
returned to the core box and stored at the core facility. The other half was bagged and shipped (via ALS Chemex
truck) to the ALS Chemex laboratory at La Serena, Chile, an independent commercial ISO 9001-certified laboratory, for
analyses.

Upon arrival at the laboratory, samples were organized, recorded, and prepared for analyses using ALS Chemex’s
Prep-31 process. This process consists of:

•
•
•
•
•
•

drying at 60°C;
crushing (jaw crusher) to minus #10 Tyler >70%;
homogenizing and splitting to 500 g with a Jones splitter;
storage of reject material (over 500 g);
pulverizing 500 g sample with a ring pulverizer to minus #200 Tyler >85%; and
storage in 250 g envelopes.

- 54 -

All samples were analyzed for 27 elements using ICP. Samples were initially analyzed using ALS Chemex procedure
ME-ICP61, which is ICP following four-acid total digestion (HF-HNO3 – HClO4 acid digestion, HCl leach) and more
recently by ME-ICP81 (see below). Copper values over 10,000 ppm were assayed using ALS Chemex method Cu-AA62,
which involved total digestion and an Atomic Absorption Spectroscopy (AAS) finish. Gold content was determined
using method Au-AA24 (30 g sample, fire assay with an AAS finish). These analytical procedures conform to industry
standards.

Drill cuttings and core were logged by geologists who also entered data into an MS Excel database. Each geologist was
responsible for entering his/her own logs. Data from these individual “unproofed” logs were printed out, and then
checked line by line against the original handwritten log by a two-geologist team. Corrections were made and a
“proofed” version of the individual log saved. Each individual “proofed” geology log was then added to a “master
geology” log. This master file can then be processed for further analysis and/or display by exporting the data in the
required format.

An independent Quality Control/Quality Assurance (QA/QC) program was implemented by Far West to monitor the
analytical results. Three types of quality control sample inserts were utilized during the drilling programs:
(i) standards; (ii) blanks; and (iii) duplicates.

The QA/QC protocols have remained largely consistent throughout all of the programs conducted by Far West. Minor
changes have been implemented to accommodate issues and recommendations from past programs, and to include
the magnetic susceptibility measurements, which is a relatively recent addition to the assay procedures.

Certified Reference Materials (CRM), or standards, are inserted every 25th sample, constituting 4% of the total
number of samples submitted. Standard samples are inserted into the sample sequence and analyzed by ALS Chemex
in a normal way.

A separate assay ledger is also kept for each hole. Initially, sample intervals and numbers are entered manually into
the ledger and then transcribed into an MS Excel spreadsheet. The initial ledgers or logs are completed by the
samplers at the drill for RC cuttings and at the core-logging facility for core. Inserted blanks, standards, and duplicates
are also recorded in this ledger. Assay results, when available from the laboratory, are cut and pasted into the digital
ledger from an MS Excel file provided by the lab. Once complete, data from the ledger are imported to a master MS
Access database containing all the Candelaria Project drill assays.

One person is responsible for management of the database, posting of final results, and controlling user access.

Security of Samples

Samples were collected at the drill in the case of RC and for the diamond drill holes, at the Far West logging facility in
Diego de Almagro. The logging facility is fenced, locked when not occupied, and is secure. Samples are handled only
by Far West employees or their designates (i.e., ALS-Chemex personnel).

Observed sample recovery was excellent and no intervals with poor recovery were reported. Apart from most
overburden material and a few obviously barren bedrock intervals, all samples were sent for analyses. Pre-laboratory
sample preparation by Harris (drilling contractor) and Far West personnel was conducted under the supervision of Far
West geologists. Samples were sealed in plastic bags using zip strips, subsequently sealed in woven polypropylene
sacs, and stored in the drilling camp until collected by ALS Chemex personnel. Once leaving the drill camp on the
property, sample security could not be confirmed. However, Far West advises that, in virtually all cases, copper
estimates in logged chips correlate well with analytical results.

Mineral Resource and Mineral Reserve Estimates

The Santo Domingo Project currently comprises of the following deposits: Santo Domingo Sur (SDS), Iris, (currently
grouped together as “SDS/IRIS”), and Iris Norte.

The mineral resource estimates for the SDS and Iris Zones have been updated by Scott Wilson RPA. The estimates
include data from recent measurements of magnetic susceptibility, as well as 35 additional drill holes completed since
the last estimate, which was carried out by Scott Wilson RPA in 2009. In addition to the 35 holes, five other holes

were used in the geological interpretation, but not in the grade interpolation, as the assay results had not been
received. The cut-off for the assay data was May 15, 2010, and the estimate is considered to be current to that date.

Based on the analysis of a Whittle™ pit optimization evaluation for varying revenue factors the chosen Whittle™ shell
was used as the basis for the detailed pit designs created for each of the Santo Domingo pits. These detailed pit
designs take into consideration, minimum mining widths, access ramps, and detailed bench configurations.

The mineral reserves estimate for the detailed open pit designs are summarized in the following table for the
probable reserve classification. The Santo Domingo Sur and Iris deposits formed the SDS/Iris open pit with Iris Norte
forming its own pit. These open pits were then further divided into various stages for mine planning purposes.
SDS/Iris pit is divided into four stages, while Iris Norte has been divided into three stages.

In general, increases in operating costs, reductions in revenue assumptions or reductions in metallurgical recovery
may result in increased cut-off grades, reductions in reserves and increasing strip ratios. The converse is also true.
Reductions in operating costs, increases in revenue assumptions or increases in metallurgical recovery may result in
reduced cut-off grades and increases in reserves.

There is currently a highway crossing over the area of the Iris Norte open pit design. This infrastructure element will
require re-location in order to mine the reserves in this area. Reserves have been estimated assuming that project
permitting is achievable.

Mining Operations

The following discussion refers to the results of the Santo Domingo Report prepared for the Santo Domingo project.
Capstone is in the process of developing a Definitive Feasibility Study (“DFS”) for the project, which is expected to be
published mid 2014 which will provide for a comprehensive project update.

The mining sequence, which mines higher grade material early on in the schedule, begins with Santo Domingo Sur.
Mining of the Santo Domingo Sur Pit will be followed by Iris, with Iris Norte mined last in the sequence. Santo
Domingo Sur and Iris form one of the pits and is divided into four stages. Iris Norte forms a separate pit and has been
split into three stages.

The production schedule for the Santo Domingo deposits was developed with the aid of MineSight™ software, and
incorporated the open pit deposits at Santo Domingo Sur, Iris and Iris Norte. The maximum processing rate of 70 ktpd
was used in the schedule.

Open pit mining will take place sequentially with Santo Domingo Sur mined first, followed by Iris and finally Iris Norte.
There will be some overlap between these pits in order to provide adequate mill feed and to balance waste stripping
requirements. The average maximum production rate from the Santo Domingo open pits is approximately 285 ktpd.
Only indicated mineral resources were used in the LOM plan.

The Santo Domingo open pits will produce 418 Mt of mill feed and 1,277 Mt of waste rock over a 19-year mine
operating life (yielding an overall strip ratio of 3.1:1 (t:t). The mine schedule focuses on achieving the required plant
feed production rate, mining of higher grade material early in schedule, while balancing waste stripping requirements.

Development

Pre-stripping of the SDS/Iris pit commences with a total of 0 Mt of waste
material mined. Approximately 0.4 Mt of ore will be stockpiled.

Mining continues in Stage 1 and 2 of SDS/Iris. Open pit ore production is
planned to be 15.3 Mt at a strip ratio of 5.8:1 (total waste mined 90 Mt).
Processing of ore commence at 60% of maximum capacity. Mined head grade
is 0.63% Cu.

Stages 1 and 2 in SDS/Iris produce 81 Mt of waste for a 3.2:1 strip ratio.
Average total mined grade is 0.63% Cu. Processing rate reaches maximum of70
kt/d.

Stage 1 of SDS/Iris is completed. Mining continues in Stage 2 and commences
in Stage 3. Processing mill head copper grade averages 0.49% Cuat a constant
throughput rate of 70 kt/d. Average total material mined is 288 kt/dat an
average strip ratio of 3.1:1.

Stage 2 of SDS/Iris pit is completed during this time frame, along with continued
mining in Stage 3 and 4. Mining commences at Iris Norte with pre-stripping of
Stage 1. A total of122 Mt of plant feed mined in the period at an average
copper grade of 0.27%Cu. Total waste tonnage is 399 Mt for an average strip
ratio of 3.3:1.

Stage 3 of SDS/Iris is completed with Stage 4 of SDS/Iris nearing completion. All
stages in Iris Norte are active during this time period

Mill feedhead grade averages 0.24% Cu. The strip ratio averages 2.8:1 with 322
Mt of waste mined. Mining completed in remaining Stage 4 of SDS/Iris and
three stages in Iris Norte. 65 Mt of ore mined and mill head grade decreases to
0.15% Cu with a total of 98 Mt of waste mined.

Waste rock from the various open pits at Santo Domingo will be deposited in engineered waste rock facilities (“WRF”)
adjacent to each of the deposits. In addition, a portion of waste rock from Iris Norte is proposed to be backfilled into
the mined out Iris pit. The 31 Mt of oxide material will also be placed in these WRF to allow for potential future
processing of this material.

The tailings storage system consists of a tailings storage facility (“TSF”) located north of the proposed mine. The TSF is
designed to store approximately 353 Mt of conventional thickened tailings, enough for approximately 18 years of the
project life. Storage of both fresh and seawater is proposed to be in lined ponds near the plant site. No other water
storage reservoir is proposed. Water make-up is proposed to be untreated seawater. Based on the conventional
thickened tailings disposal method, the estimated water make-up will be approximately 1,450 m3/h (~400 L/s). The
TSF includes a starter dam for storing at least two years of thickened tailings. The starter dam crest will be raised in
stages by the downstream method to contain the waste tailings within the current permitted boundary limits up to
Year 18 of operations.

Basic layouts have been prepared based on an open-air concentrator design, with mobile crane maintenance access
and minimal overhead cranage. This layout has taken account of the site topography and limits imposed by the
preliminary locations of the pit, stockpiles, and waste dumps.

The land and territory investigations regarding the project’s current footprint, indicate there would be no impact on
natural parks, biodiversity conservation priority sites, or indigenous development land in the Atacama Region. A
series of baseline studies are still required for the project in order to achieve a proper characterization of the
environmental components that should be included in the future Environmental Impact Study (EIS).

No direct marketing has been done for the potential Santo Domingo copper concentrates and therefore no off-take
agreements beyond that with KORES exist.

The iron ore produced by the Santo Domingo Project will be suitable to be sold as a pellet feed. A series of
assumptions can be made around which the specific price forecast can be based.

• Market: the product will be sold into China as a pellet feed, most likely to one of the new world scale coastal

•

pellet plants operated by the larger steel companies.
Logistics: as a large bulk shipment it can be presumed that a Chinese steel mill will use a 155,000 capesize
vessel to transport the ore from Chile to a port in Northern China, most likely Qingdao, a distance of 10,376
nautical miles. In this instance it is almost certain that any price negotiations will be based upon the steel
company using a ship under a time charter agreement; the reason for a COA or owning a ship is to give the
steel mill a freight advantage, this will not be ceded in price negations.
Pricing point: The large coastal pellet plants in China, which are most likely to purchase the ore from the
project, will value it against pellet feed from the major supplier of imported material, in this case Brazil.
Therefore, the correct benchmark price to be used will be Vale’s MBR pellet feed price (fob Tubarao). The
MBR pellet feed price is typically set at a 3% discount to sinter fines and this is unlikely to change in future.
There is an argument to price directly against a Chinese concentrate price series, but the market for this type
of product is small and in practise restricted to inland steel mills.

The total project capital cost estimate is summarized in in the table below and have ±25% accuracy as of July 2011.
The estimate is based on a foreign exchange rate of 1 US$ = 466 Chilean Pesos (CLP) and must be assessed against the

Note that the guidance for the capital cost was revised to $1.5 to $1.8 billion on March 13, 2013. The DFS, expected in
mid-2014, will provide a complete update on the project economics.

The total cash production costs for copper over the life of the project were estimated at $0.11 per pound of payable
copper, including gold and iron production as credits and selling costs. The co-product total cash production costs
were estimated at $1.12 per pound of payable copper and $30.46 per tonne of magnetite concentrate.

A project implementation schedule will be updated and included in the DFS.

Updated Capital Cost Estimate

AMEC, NCL and Capstone personnel completed an update to the PFS estimate of the development capital required to
build the Santo Domingo Project on March 13, 2013 The capital cost at that time was estimated at between $1.5 to
$1.8 billion. This estimate was dependent upon flow sheet variables and mine equipment lease/purchase options.
This estimate includes all site infrastructure and indirect costs including the pipelines and port facility. With the
exception of moving the port location, the overall project design has not changed materially from the PFS design;
however, a more detailed estimate will be provided with the DFS in the second quarter.

Exploration and Development

Exploration on the property will focus on identifying untested or poorly tested geophysical targets for smaller lenses
of potentially high grade material. Previous exploration has been focused on identifying and delineating the main ore
body which is now complete. Additional small, near surface higher grade lenses could potentially improve the
economics of the overall project.

ITEM 4 - RISK FACTORS

Capstone is subject to a number of significant risks due to the nature of its business and the present stage of its
business development. Readers should carefully consider the risks and uncertainties described below before deciding
whether to invest in Capstone common shares. Capstone’s failure to successfully address the risks and uncertainties
described below could have a material adverse effect on its business, financial condition and/or results of operations,
and the trading price of its common shares may decline and investors may lose all or part of their investment.
Capstone cannot give assurance that it will successfully address these risks or other unknown risks that may affect its
business.

Mining is inherently dangerous and subject to conditions or events beyond the Company’s control, the occurrence of
which could have a material adverse effect on the Company’s business, financial condition, results of operations and
prospects.

The Company’s operations are subject to all the hazards and risks normally encountered in the exploration,
development and production of copper and other metals, including, without limitation, fires, power outages, labour
disruptions, flooding, explosions, cave-ins, landslides and other geotechnical instabilities, metallurgical and other
processing problems and other conditions involved in the mining of minerals, any of which could result in damage to,
or destruction of, the Company’s mines, plants and equipment, personal injury or loss of life, environmental damage,
delays in mining, increased production costs, asset write-downs, monetary losses and legal liability. The occurrence of
any of these events could result in a prolonged interruption in the Company’s operations that would have a material
adverse effect on the Company’s business, financial condition, results of operations and prospects.

Changes in the market price of copper and other metals, which in the past have fluctuated widely, could negatively
affect the profitability of the Company’s operations and financial condition.

The commercial viability of the Company’s properties and the Company’s ability to sustain operations is dependent
on, among other things, the market price of copper, lead, zinc, gold and silver. Depending on the price to be received
for any minerals produced, the Company may determine that it is impractical to continue commercial production at
the Pinto Valley Mine, the Cozamin Mine or the Minto Mine or to develop the Santo Domingo Project. A reduction in
the market price of copper, lead, zinc, gold or silver may prevent the Company’s properties from being economically
mined or result in the write-off of assets whose value is impaired as a result of low metals prices. The market price of
copper, lead, zinc, gold and silver is volatile and is impacted by numerous factors beyond the Company’s control,
including, among others:













international economic and political conditions;
expectations of inflation or deflation;
international currency exchange rates;
interest rates;
global or regional consumptive patterns;
speculative activities;
levels of supply and demand;
increased production due to new mine developments;
decreased production due to mine closures;
improved mining and production methods;
availability and costs of metal substitutes;

- 61 -

 metal stock levels maintained by producers and others; and


inventory carrying costs.

The effect of these factors on the price of base and precious metals cannot be accurately predicted and there can be
no assurance that the market price of these metals will remain at current levels or that such prices will improve. A
decrease in the market price of copper, lead, zinc, gold or silver would affect the profitability of the Pinto Valley Mine,
the Cozamin Mine and the Minto Mine and could affect the Company’s ability to finance the exploration and
development of the Company’s other properties, which would have a material adverse effect on the Company’s
business, financial condition, results of operations and prospects.

The sale of the Company’s metals is subject to counterparty and market risks.

The Company has entered into concentrate off-take agreements whereby 100% of budgeted production of the
concentrate produced from the Pinto Valley, Cozamin and Minto Mines have been committed to various external
parties through calendar year 2014. Thereafter, approximately 50% is committed under multi-year contracts through
2016. The balance is not currently committed but various interested parties have requested intent to purchase this
concentrate if available. 50% of the copper and iron concentrate to be produced from the Santo Domingo Project will
be purchased by Kores under the terms of the Shareholders Agreement. The Company has also sold forward the gold
and silver production from the Minto Mine and all of the silver production from the Cozamin Mine to Silver Wheaton.
If any counterparty to any off-take or forward sales agreement does not honour such arrangement, or should any such
counterparty become insolvent, the Company may incur losses on the production already shipped and/or be forced to
sell a greater volume of the Company’s production in the spot market, which is subject to market price fluctuations. In
addition, there can be no assurance that the Company will be able to renew any of the Company’s off-take or forward
sales agreements on acceptable terms, or at all, or that the Company’s production will meet the qualitative
requirements under such agreements.

The Company may require substantial additional capital to accomplish the Company’s exploration and development
plans, and there can be no assurance that financing will be available on terms acceptable to the Company, or at all.

The Company may require substantial additional financing to accomplish the Company’s exploration and development
plans for the Santo Domingo Project and to advance the Pinto Valley Mine, the Cozamin Mine and the Minto Mine to
achieve designed production rates. These financing requirements could adversely affect the Company’s credit ratings
and the Company’s ability to access the capital markets in the future. Failure to obtain sufficient financing, or
financing on terms acceptable to the Company, may result in a delay or indefinite postponement of exploration,
development or production at one or more of the Company’s properties. Additional financing may not be available
when needed and the terms of any agreement could impose restrictions on the operation of the Company’s business.
Failure to raise financing when needed could have a material adverse effect on the Company’s business, financial
condition, results of operations and prospects.

Fluctuations in foreign currency exchange rates could have an adverse effect on the Company’s business, financial
condition, results of operations and prospects.

Fluctuations in the Canadian dollar or Mexican peso relative to the US dollar could significantly affect the Company’s
business, financial condition, results of operations and prospects. Exchange rate movements can have a significant
impact on the Company as all of the Company’s revenue is received in US dollars but much of the Company’s
operating and capital costs are incurred in Canadian dollars and Mexican pesos. Also, as a result of the Company’s
acquisition of Far West, the Company is exposed to currency fluctuations in the Chilean peso relating to expenditures
for the Santo Domingo Project. As a result, a strengthening of these currencies relative to the US dollar will reduce the
profitability of the Company’s projects and affect the Company’s ability to continue to finance the Company’s
operations. The Company does not currently, and does not expect to, enter into foreign currency contracts to hedge
against currency risk.

The Company’s calculations of mineral resources and mineral reserves are estimates and are subject to uncertainty.

The Company’s calculations of mineral resources and mineral reserves are estimates and depend upon geological
interpretation and statistical inferences drawn from drilling and sampling analysis, which may prove to be inaccurate.

- 62 -

Actual recoveries of copper, lead, zinc, gold and silver from mineralized material may be lower than those indicated by
test work. Any material change in the quantity of mineralization, grade or stripping ratio, may affect the economic
viability of the Company’s properties. In addition, there can be no assurance that metal recoveries in small-scale
laboratory tests will be duplicated in larger scale tests under on-site conditions or during production. Notwithstanding
pilot plant tests for metallurgy and other factors, there remains the possibility that the ore may not react in
commercial production in the same manner as it did in testing. Mineral resources that are not mineral reserves do not
have demonstrated economic viability. Mining and metallurgy are inexact sciences and, accordingly, there always
remains an element of risk that a mine may not prove to be commercially viable.

Until a deposit is actually mined and processed, the quantity of mineral resources and mineral reserves and grades
must be considered as estimates only. In addition, the quantity of mineral resources and mineral reserves may vary
depending on, among other things, metal prices, cut-off grades and operating costs. Any material change in quantity
of mineral reserves, mineral resources, grade, percent extraction of those mineral reserves recoverable by
underground mining techniques or the stripping ratio for those mineral reserves recoverable by open pit mining
techniques may affect the economic viability of the Company’s mining projects.

General economic conditions or changes in consumption patterns may adversely affect the Company’s growth and
profitability.

Many industries, including the base and precious metals mining industry, are impacted by global market conditions.
Some of the key impacts of the recent financial market turmoil include contraction in credit markets resulting in a
widening of credit risk, devaluations and high volatility in global equity, commodity, foreign exchange and metals
markets, and a lack of market liquidity. A continued or worsened slowdown in the financial markets or other
economic conditions, including, but not limited to, reduced consumer spending, increased unemployment rates,
deteriorating business conditions, inflation, deflation, volatile fuel and energy costs, increased consumer debt levels,
lack of available credit, changes in interest rates and changes in tax rates may adversely affect the Company’s growth
and profitability potential. Specifically:








a global credit/liquidity issue could impact the cost and availability of financing and the Company’s overall
liquidity;
volatility of prices for copper, lead, zinc, gold and/or silver prices may impact the Company’s future revenues,
profits and cash flows;
recessionary pressures could adversely impact demand for the Company’s production;
volatile energy prices, commodity and consumables prices and currency exchange rates could negatively
impact potential production costs; and
devaluation and volatility of global stock markets could impact the valuation of the Company’s securities,
which may impact the Company’s ability to raise funds through future issuances of equity.

These factors could have a material adverse effect on the Company’s business, financial condition, results of
operations and prospects.

There are uncertainties and risks related to the potential development of the Santo Domingo Project and if the
construction and development of this project is not completed, it could adversely affect the Company’s business,
financial condition, results of operations and prospects.

As part of the Company’s strategy, the Company will continue the Company’s efforts to develop new mineral projects,
including, if advisable, the Santo Domingo Project. Development of the Santo Domingo Project will require obtaining
permits and financing, and the construction and operation of mines, processing plants and related infrastructure. As a
result, if the Company proceeds to development it will be subject to all of the risks associated with establishing new
mining operations, including:



the timing and cost, which can be considerable, of the construction of mining and processing facilities and
related infrastructure;
the availability and cost of skilled labour, mining equipment and principal supplies needed for operations,
including explosives, fuels, chemical reagents, water, power, equipment parts and lubricants;

- 63 -




the availability and cost of appropriate smelting and refining arrangements;
the need to obtain necessary environmental and other governmental approvals and permits and the timing of
the receipt of those approvals and permits;
the availability of funds to finance construction and development activities;
industrial accidents;



 mine failures, shaft failures or equipment failures;





natural phenomena such as inclement weather conditions, floods, droughts, rock slides and seismic activity;
unusual or unexpected geological and metallurgic conditions;
exchange rate and commodity price fluctuations;
potential opposition from non-governmental organizations, environmental groups or local groups, which may
delay or prevent development activities; and
restrictions or regulations imposed by governmental or regulatory authorities.



The costs, timing and complexities of developing the Company’s projects may be greater than anticipated.

Cost estimates may increase significantly as more detailed engineering work is completed on a project. It is common
in mining operations to experience unexpected costs, problems and delays during construction, development and
mine start-up. Accordingly, the Company cannot provide assurance that the Company’s activities will result in
profitable mining operations at the Company’s mineral properties. If there are significant delays in when these
projects are completed and are producing on a commercial and consistent scale, and/or their capital costs were to be
significantly higher than estimates, these events could have a significant adverse effect on the Company’s results of
operation, cash flow from operations and financial condition.

High metal prices in recent years have encouraged increased mineral exploration, development and production
activity, which has increased demand for, and cost of, exploration, development and construction services and
equipment.

Notwithstanding short term market fluctuations, high metal prices in recent years have encouraged increases in
mineral exploration, development and production activities, which has resulted in increased demand for, and cost of,
exploration, development and construction services and equipment. There has also been a shortage of skilled workers
in the mining industry in recent years, particularly with respect to experienced mine construction and mine
management personnel. In addition, employee turnover rates in the mining industry have increased as participants in
the minerals industry compete for skilled personnel. Increased demand for services and equipment could result in
delays if services or equipment cannot be obtained in a timely manner due to inadequate availability, and may cause
scheduling difficulties due to the need to coordinate the availability of services or equipment, any of which could
materially increase the Company’s project exploration and any development and/or construction costs. Increases in
both operating and capital costs must be factored into economic assessments of existing and proposed mining
projects. These increases may increase the financing requirements for such projects or render such projects
uneconomic.

Mineral rights or surface rights to the Company’s properties could be challenged, and, if successful, such challenges
could have a material adverse effect on the Company’s production and the Company’s business, financial condition,
results of operations and prospects.

Title to the Company’s properties may be challenged or impugned. The Company’s property interests may be subject
to prior unregistered agreements or transfers and title may be affected by undetected defects. Surveys have not been
carried out on the majority of the Company’s properties and, therefore, in accordance with the laws of the jurisdiction
in which such properties are situated, their existence and area could be in doubt.

A claim by a third party asserting prior unregistered agreements or transfer on any of the Company’s properties,
especially where mineral reserves have been located, could result in the Company losing a commercially viable
property. Even if a claim is unsuccessful, it may potentially affect the Company’s current operations due to the high
costs of defending against the claim and its impact on the Company’s senior management’s time. Title insurance is
generally not available for mineral properties and the Company’s ability to ensure that the Company has obtained a

- 64 -

secure claim to individual mineral properties or mining concessions may be severely constrained. The Company relies
on title information and/or representations and warranties provided by the Company’s grantors. If the Company loses
a commercially viable property, such a loss could lower the Company’s future revenues or cause the Company to
cease operations if the property represented all or a significant portion of the Company’s mineral reserves at the time
of the loss.

The Company faces added risks and uncertainties as a result of operating in foreign jurisdictions including changes in
regulation.

The Company’s business operates in a number of foreign countries where there are added risks and uncertainties due
to the different economic, cultural and political environments. The Company’s mineral exploration and mining
activities may be adversely affected by political instability and changes to government regulation relating to the
mining industry. Other risks of foreign operations include political unrest, labour disputes and unrest, invalidation of
governmental orders and permits, corruption, war, civil disturbances and terrorist actions, arbitrary changes in law or
policies of particular countries (including nationalization of mines), foreign taxation, price controls, delays in obtaining
or renewing or the inability to obtain or renew necessary environmental permits, opposition to mining from
environmental or other non-governmental organizations, limitations on foreign ownership, limitations on the
repatriation of earnings, limitations on mineral exports and increased financing costs. For example, recent changes in
the Mexican tax laws, including the imposition of a royalty, have had an impact on the Company’s results and there is
no certainty further changes will not be imposed. Local economic conditions, including higher incidences of criminal
activity and violence in areas of Mexico can also adversely affect the security of the Company’s operations and the
availability of supplies. In addition, risks of operations in Mexico include extreme fluctuations in currency exchange
rates, high rates of inflation, hostage taking and expropriation. These risks may limit or disrupt the Company’s
projects, restrict the movement of funds or result in the deprivation of contract rights or the taking of property by
nationalization or expropriation without fair compensation. There can be no assurance that changes in the
government or laws or changes in the regulatory environment for mining companies or for non-domiciled companies
will not be made that would adversely affect the Company’s business, financial condition, results of operation and
prospects.

It may be difficult for the Company to find and hire qualified people in the mining industry who are situated in Arizona,
Mexico, Chile and Yukon or to obtain all of the necessary services or expertise in Arizona, Mexico, Chile and Yukon or to
conduct operations on the Company’s projects at reasonable rates.

If qualified people and services or expertise cannot be obtained in Arizona, Mexico, Chile and Yukon, the Company
may need to seek and obtain those services from people located outside of these areas, which will require work
permits and compliance with applicable laws and could result in delays and higher costs to conduct operations in
Arizona, Mexico, Chile and Yukon.

The Company’s operations are subject to significant governmental regulation, which could significantly limit the
Company’s exploration and production activities.

The Company’s mineral exploration and development activities are subject to governmental approvals and various
laws and regulations governing development, operations, taxes, labour standards and occupational health, mine
safety, toxic substances, land use, water use and land claims affecting local, First Nations and Aboriginal populations.
The liabilities and requirements associated with the laws and regulations related to these and other matters may be
costly and time-consuming and may restrict, delay or prevent commencement or continuation of exploration or
production operations. The Company cannot provide definitive assurance that it has been or will be at all times in
compliance with all applicable laws and regulations. Failure to comply with applicable laws and regulations may result
in the assessment of administrative, civil and criminal penalties, the imposition of cleanup and site restoration costs
and liens, the issuance of injunctions to limit or cease operations, the suspension or revocation of permits or
authorizations and other enforcement measures that could have the effect of limiting or preventing production from
the Company’s operations. The Company may incur material costs and liabilities resulting from claims for damages to
property or injury to persons arising from the Company’s operations. If the Company is pursued for sanctions, costs
and liabilities in respect of these matters, the Company’s mining operations and, as a result, the Company’s financial
performance, financial position and results of operations, could be materially and adversely affected.

- 65 -

In addition, no assurance can be given that new rules and regulations will not be enacted or that existing rules and
regulations will not be applied in a manner that could limit or curtail the Company’s exploration, development or
production. Amendments to current laws, regulations and permits governing operations and activities of mining and
exploration companies, or the more stringent implementation thereof, could have a material adverse impact on the
Company and cause increases in the Company’s exploration expenses, capital expenditures or production costs or a
reduction in the levels of production at the Company’s producing properties or require abandonment or delays in
exploring or developing the Company’s properties.

The Company is dependent on key management personnel.

The Company is very dependent upon the personal efforts and commitment of the Company’s existing management
and the Company’s current operations and future prospects depend on the experience and knowledge of these
individuals. The Company does not maintain any “key person” insurance. To the extent that one or more of the
Company’s members of management are unavailable for any reason, or should the Company lose the services of any
of them, a disruption to the Company’s operations could result, and there can be no assurance that the Company will
be able to attract and retain a suitable replacement.

The Company’s operations are subject to stringent environmental laws and regulations that could significantly limit the
Company’s ability to conduct the Company’s business.

The Company’s operations are subject to various laws and regulations governing the protection of the environment,
exploration, development, production, taxes, labour standards, occupational health, waste disposal, safety and other
matters. Environmental legislation provides for restrictions and prohibitions on spills, releases or emissions of various
substances produced in association with certain mining operations, such as seepage from tailings disposal areas,
which would result in environmental pollution. A breach of such legislation may result in the imposition of fines and
penalties. In addition, certain of the Company’s operations require the submission and approval of environmental
impact assessments. Environmental legislation is evolving in the direction of stricter standards and enforcement,
higher fines and penalties for non-compliance, more stringent environmental assessments of proposed projects and a
heightened degree of responsibility for companies and their directors, officers and employees. Compliance with
changing environmental laws and regulations may require significant capital outlays, including obtaining additional
permits, and may cause material changes or delays in, or the cancellation of, the Company’s exploration programs or
current operations.

The Company is required to obtain, maintain and renew environmental, construction and mining permits, which is
often a costly and time-consuming process.

Mining companies, including the Company, need many environmental, construction and mining permits, each of
which can be time-consuming and costly to obtain, maintain and renew. In connection with the Company’s current
and future operations, the Company must obtain and maintain a number of permits that impose strict conditions,
requirements and obligations on the Company, including those relating to various environmental and health and
safety matters. To obtain, maintain and renew certain permits, the Company is required to conduct environmental
assessments pertaining to the potential impact of the Company’s current and future operations upon the environment
and to take steps to avoid or mitigate those impacts. For example, additional permits will be required to fully exploit
the resources at Pinto Valley and Minto. There is a risk that the Company will not be able to obtain such permits or
that obtaining such permits will require more time and capital than anticipated.

Permit terms and conditions can also impose restrictions on how the Company conducts the Company’s operations
and limit the Company’s flexibility in developing the Company’s mineral properties. Many of the Company’s permits
are subject to renewal from time to time, and renewed permits may contain more restrictive conditions than the
Company’s existing permits. In addition, the Company may be required to obtain new permits to expand the
Company’s operations, and the grant of such permits may be subject to an expansive governmental review of the
Company’s operations. Alternatively, the Company may not be successful in obtaining such permits, which could
prevent the Company from commencing or expanding operations or otherwise adversely affect the Company’s
business, financial condition, results of operation and prospects. For instance, although the Minto Mine is currently
permitted to conduct operations under its Quartz Mining Licence and two Water Use Licences, amendments to these
licences are required in order to implement the Company’s planned mine expansion. These amendments may not be

- 66 -

granted by the Yukon regulatory authorities. Further, renewal of the Company’s existing permits or obtaining new
permits may be more difficult if the Company is not able to comply with the Company’s existing permits. Applications
for permits, permit area expansions and permit renewals may be subject to challenge by interested parties, which can
delay or prevent receipt of needed permits. The permitting process can also vary by jurisdiction in terms of its
complexity and likely outcomes.

Accordingly, permits required for the Company’s operations may not be issued, maintained or renewed in a timely
fashion or at all, may be issued or renewed upon conditions that restrict the Company’s ability to conduct the
Company’s operations economically, or may be subsequently revoked. Any such failure to obtain, maintain or renew
permits, or other permitting delays or conditions, including in connection with any environmental impact analyses,
could have a material adverse effect on the Company’s business, results of operations, financial condition and
prospects.

Climatic conditions can affect the Company’s operations at the Pinto Valley, Cozamin and Minto Mines.

Arizona can be subject to period of drought. Operations at the Pinto Valley Mine require water for normal operations.
The Company has entered to a Water Supply Agreement with BHP Copper but such agreement is subject to water
availability and BHP’s own requirements. A lack of necessary water for a prolonged period of time could affect
operations at the Pinto Valley Mine and materially adversely affect the Company’s results of operations. Arizona can
also be subject to significant rainfall which could result in flooding of pits at the Pinto Valley Mine adversely affecting
the Company’s results of operations.

Operations at the Cozamin Mine are also subject to adverse extreme weather conditions. Drought has been prevalent
in Central Mexico for years and the effects of lack of water might disrupt normal process operations. As a proactive
measure, Cozamin has made agreements with local government and water rights owners for the purchase and use of
water from offsite sources.

Operations at the Minto Mine may be subject to extreme weather conditions. Unseasonable weather conditions may
preclude normal work patterns and can severely limit the Company’s mining operations, resulting in additional costs
and delays. In the recent past, Yukon experienced extreme weather conditions that resulted in abnormally high run-
off at the Minto Mine, exceeding the normal containment capacity of the mine site. As a result, the Company decided
to fill the Minto Mine main pit with water, which caused the Company to cease mining operations until the Company
obtained regulatory permission to discharge the excess waters. Future extreme weather in Yukon could again result in
excess run-off at the mine site, which could have an adverse effect on the results of operations at the Minto Mine and
on the Company’s business, financial condition, results of operation and prospects.

The Company’s directors and officers may have interests that conflict with the Company’s interests.

Certain of the Company’s directors and officers also serve as directors or officers, or have significant shareholdings in,
other companies that are similarly engaged in the business of acquiring, developing and exploiting natural resource
properties. To the extent that such other companies may participate in ventures which the Company may participate
in, or in ventures which the Company may seek to participate in, the Company’s directors and officers may have a
conflict of interest in negotiating and concluding terms respecting the extent of such participation. In all cases where
the Company’s directors and officers have an interest in other companies, such other companies may also compete
with the Company for the acquisition of mineral property investments. As a result of these conflicts of interest, the
Company may not have an opportunity to participate in certain transactions, which may have a material adverse
effect on the Company’s business, financial condition, results of operation and prospects.

Aboriginal title claims and rights to consultation and accommodation may affect the Company’s existing operations as
well as development projects and future acquisitions.

The nature and extent of First Nations rights and title remains the subject of active debate, claims and litigation in
Canada, including in British Columbia and Yukon. The Minto Mine lies on Category A land in Yukon where the Selkirk
First Nation own both surface and subsurface rights. The Kutcho Project in British Columbia lies within an area
claimed as traditional territory by both the Tahltan First Nation and the Kaska First Nation. There is a risk that any
land claim settlement with the Tahltan or the Kaska may adversely affect the Company’s rights to the Kutcho Project.

- 67 -

There can be no guarantee that the unsettled nature of the land claims in British Columbia and Yukon will not create
delays in project approval or unexpected interruptions in project progress, or result in additional costs to advance the
Company’s projects. In many cases, environmental assessment, subsequent permitting, development and operation
of proposed projects is only possible with the support of the local First Nations group. In order to secure such support,
the Company may have to take measures to limit the adverse impact to, and ensure that some of the economic
benefits of the construction and mining activity will be enjoyed by, the local First Nations group. There is a risk that
the First Nations may publicly oppose the proposed project at any stage and this potential opposition may adversely
affect the project or the Company’s public image. Further, Canadian law related to aboriginal rights, including
aboriginal title rights, is in a period of change. There is a risk that future changes to the law may adversely affect the
Company’s rights to the Minto Mine,.

The Company’s insurance does not cover all potential losses, liabilities and damage related to the Company’s business
and certain risks are uninsured or uninsurable.

In the course of exploration, development and production of mineral properties, certain risks, including rock bursts,
cave-ins, fires, flooding and earthquakes may occur. It is not always possible to fully insure against such risks. The
Company currently does not have insurance against all such risks and may decide not to take out insurance against all
such risks as a result of high premiums or other reasons. Further, insurance against certain risks, including those
related to environmental matters, is generally not available to the Company or to other companies within the mining
industry. Losses from these events may cause the Company to incur significant costs that could have a material
adverse effect on the Company’s business, financial condition, results of operation and prospects.

Land reclamation and mine closure requirements may be burdensome and costly.

Land reclamation and mine closure requirements are generally imposed on mining companies, such as the Company’s,
which require the Company, among other things, to minimize the effects of land disturbance. Such requirements may
include controlling the discharge of potentially dangerous effluents from a site and restoring a site’s landscape to its
pre-exploration form. The actual costs of reclamation and mine closure are uncertain and planned expenditures may
differ from the actual expenditures required. Therefore, the amount that the Company is required to spend could be
materially higher than current estimates. Any additional amounts required to be spent on reclamation and mine
closure may have a material adverse effect on the Company’s financial performance, financial position and results of
operations and may cause the Company to alter the Company’s operations. Although the Company includes liabilities
for estimated reclamation and mine closure costs in the Company’s financial statements, it may be necessary to spend
more than what is projected to fund required reclamation and mine closure activities.

The Company’s operations will be adversely affected if the Company fails to maintain satisfactory labour relations.

As of December 31, 2013, the Company had approximately 1,307 employees and approximately 626 contractors.

The company’s workforce is not unionized with the exception of approximately 354 of the hourly employees at the
Pinto Valley Mine which are members of six unions, governed by one collective bargaining agreement negotiated by
the United Steelworkers Union.

The Company cannot predict at this time whether the Company will be able to reach new agreements with the
Company’s unionized workforce without a work stoppage or other labour unrest, and any such new agreements may
not be on terms favourable to the Company. Additional groups of non-union employees may seek union
representation in the future. Further, relations with employees may be affected by changes in the scheme of labour
relations that may be introduced by the relevant governmental authorities in jurisdictions where the Company
conducts business. Changes in such legislation or otherwise in the Company’s relationship with the Company’s
employees may result in higher ongoing labour costs, employee turnover, strikes, lockouts or other work stoppages,
any of which could have a material adverse effect on the Company’s business, results of operations and financial
condition.

Increased energy prices could adversely affect the Company’s results of operations and financial condition.

Mining operations and facilities are intensive users of electricity and carbon-based fuels. Energy prices can be affected

- 68 -

by numerous factors beyond the Company’s control, including global and regional supply and demand, political and
economic conditions, and applicable regulatory regimes. The prices of various sources of energy may increase
significantly from current levels. An increase in energy prices for which the Company is not hedged could materially
adversely affect the Company’s results of operations and financial condition.

The Company may be unable to compete successfully with other mining companies.

The mining industry is competitive in all of its phases. The Company faces strong competition from other mining
companies in connection with the acquisition of properties producing, or capable of producing, metals. Many of these
companies have greater liquidity, greater access to credit and other financial resources, newer or more efficient
equipment, lower cost structures, more effective risk management policies and procedures and/or a greater ability
than the Company to withstand losses. The Company’s competitors may be able to respond more quickly to new laws
or regulations or emerging technologies, or devote greater resources to the expansion or efficiency of their operations
than the Company can. In addition, current and potential competitors may make strategic acquisitions or establish
cooperative relationships among themselves or with third parties. Accordingly, it is possible that new competitors or
alliances among current and new competitors may emerge and gain significant market share to the Company’s
detriment. The Company may also encounter increasing competition from other mining companies in the Company’s
efforts to hire experienced mining professionals. Increased competition could adversely affect the Company’s ability
to attract necessary capital funding, to acquire it on acceptable terms, or to acquire suitable producing properties or
prospects for mineral exploration in the future. As a result of this competition, the Company may not be able to
compete successfully against current and future competitors, and any failure to do so could have a material adverse
effect on the Company’s business, financial condition, results of operations and prospects.

The Company may experience difficulties with the Company’s strategic partners.

The Company currently operates the Santo Domingo Project through a joint ownership arrangement with KORES and
the Company may in the future enter into additional joint ownership arrangements with other partners. The
Company is subject to the risks normally associated with the conduct of joint ownership arrangements, which include
disagreements with the Company’s strategic partners on how to develop, operate and finance the Company’s joint
ownership activities, including future acquisitions or the Santo Domingo Project, and possible disputes with the
Company’s strategic partners regarding joint ownership arrangement matters. These disagreements and disputes may
have an adverse effect on the Company’s ability to successfully pursue joint ownership arrangements, including the
development of the Santo Domingo Project, which could affect the Company’s business, financial condition, results of
operation and prospects.

The Company may experience problems integrating new acquisitions into the Company’s existing operations.

The Company’s success at completing acquisitions will depend on a number of factors, including, but not limited to,
identifying acquisitions that fit the Company’s strategy, negotiating acceptable terms with the seller of the business or
property to be acquired and obtaining approval from regulatory authorities in the jurisdictions of the business or
property to be acquired. Any positive effect on the Company’s results from the Company’s acquisitions, including the
recent Pinto Valley acquisition, will depend on a variety of factors, including, but not limited to, assimilating the
operations of an acquired business or property in a timely and efficient manner, maintaining the Company’s financial
and strategic focus while integrating the acquired business or property, implementing uniform standards, controls,
procedures and policies at the acquired business, as appropriate, and to the extent that the Company makes an
acquisition outside of markets in which the Company has previously operated, conducting and managing operations in
a new operating environment. The Pinto Valley Mine was acquired on an “as is where is” basis with limited
representations and warranties. In addition the Company has provided indemnities to BHP Copper with respect to
certain liabilities and has limited recourse against BHP Copper with respect to many potential liabilities related to the
Pinto Valley Mine. As a result, the acquisition of mineral properties, such as the Pinto Valley Mine, may subject the
Company to unforeseen liabilities, including environmental liabilities.

ITEM 5 - DIVIDENDS AND DISTRIBUTIONS

The Company has neither declared nor paid any dividends or distributions on its common shares in the last three
financial years and has no present intention of paying dividends or distributions on its common shares, as it

- 69 -

anticipates that all available funds will be invested to finance the growth of its business.

ITEM 6 - DESCRIPTION OF CAPITAL STRUCTURE

6.1

General Description of Capital Structure

The Company has an authorized capital of an unlimited number of common shares without par value, 379,853,023 of
which were issued and outstanding as of December 31, 2013.

Common Shares

The holders of the common shares are entitled to receive notice of and to attend and vote at all meetings of the
shareholders of the Company and each common share confers the right to one vote in person or by proxy at all
meetings of the shareholders of the Company. The holders of the common shares, subject to the prior rights, if any,
of the holders of any other class of shares of the Company, are entitled to receive such dividends in any financial year
as the Board of Directors of the Company may determine. In the event of liquidation, dissolution or winding-up of the
Company, whether voluntary or involuntary, the holders of the common shares are entitled to receive, subject to the
prior rights, if any, of the holders of any other class of shares of the Company, the remaining property and assets of
the Company.

Incentive Stock Option and Bonus Share Plan

The Company has an Incentive Stock Option and Bonus Share Plan in place which provides for the issuance of stock
options to acquire at any time up to a maximum of 10% of the Company’s issued and outstanding common shares
(subject to standard anti-dilution adjustments). The plan further allows for the issuance of up to 500,000 bonus
shares in any one calendar year to employees or directors of the Company. Any bonus shares that are issued are not
counted in determining the number of options available to be granted under the plan.

Deferred Share Units (“DSUs”)

The Company has a DSU Plan which aligns the interests of non-executive directors with those of the shareholders of
the Company and provides a compensation system for eligible directors that, together with the other director
compensation mechanisms of the Company, is reflective of the responsibility, commitment and risk accompanying
Board membership and the performance of the duties required of the various committees of the Board. Directors will
be able to redeem their DSUs only after they cease to be directors of the Company.

Performance Share Units (“PSUs”) and Restricted Share Units (“RSUs”)

The Company also has long-term incentive plans designed to align management’s interests with those of shareholders
through grants of PSUs and RSUs. The value of earned share units fluctuates with the value of the Company’s shares.
PSUs vest only when certain three-year performance-based criteria are achieved, while RSUs vest at the end of a
three-year term based on the executive’s continued employment.

8.2

Cease Trade Orders, Bankruptcies, Penalties or Sanctions

To the knowledge of the Company, no director or executive officer of the Company is, as at the date of this Annual
Information Form, or was, within 10 years before the date of this Annual Information Form, a director, chief executive
officer (“CEO”) or chief financial officer (“CFO”) of any company (including the Company) that:

(a)

(b)

was the subject, while the director or executive officer was acting in the capacity as director, CEO or CFO
of such company, of a cease trade or similar order or an order that denied the relevant company access
to any exemption under securities legislation, that was in effect for a period of more than 30 consecutive
days; or
was subject to a cease trade or similar order or an order that denied the relevant company access to any
exemption under securities legislation, that was in effect for a period of more than 30 consecutive days,
that was issued after the director or executive officer ceased to be a director, CEO or CFO but which
resulted from an event that occurred while the proposed director was acting in the capacity as director,
CEO or CFO of such company.

Other than as set out herein, to the knowledge of the Company, none of the Company’s directors or executive officers
or any shareholder holding a sufficient number of securities of the Company to affect materially the control of the
Company:

(a)

(b)

is, as at the date of this Annual Information Form, or has been within 10 years before the date of this
Annual Information Form, a director or executive officer of any company (including the Company) that,
while that person was acting in that capacity, or within a year of that person ceasing to act in that
capacity, became bankrupt, made a proposal under any legislation relating to bankruptcy or insolvency
or was subject to or instituted any proceedings, arrangement or compromise with creditors or had a
receiver, receiver manager or trustee appointed to hold its assets;
has, within the 10 years before the date of this Annual Information Form, become bankrupt, made a
proposal under any legislation relating to bankruptcy or insolvency, or become subject to or instituted

- 74 -

any proceedings, arrangement or compromise with creditors, or had a receiver, receiver manager or
trustee appointed to hold the assets of the director, executive officer or shareholder;
has been subject to any penalties or sanctions imposed by a court relating to securities legislation or by a
securities regulatory authority or has entered into a settlement agreement with a securities regulatory
authority; or
has been subject to any penalties or sanctions imposed by a court or regulatory body that would likely be
considered important to a reasonable investor in making an investment decision.

(c)

(d)

8.3

Conflicts of Interest

Certain of the Company’s directors and officers serve or may agree to serve as directors or officers of other reporting
companies or have significant shareholdings in other reporting companies and, to the extent that such other
companies may participate in ventures in which the Company may participate, the directors of the Company may have
a conflict of interest in negotiating and concluding terms respecting the extent of such participation. In the event that
such a conflict of interest arises at a meeting of the Company’s directors, a director who has such a conflict will abstain
from voting for or against the approval of such participation or such terms and such director will not participate in
negotiating and concluding terms of any proposed transaction. From time to time, several companies may participate
in the acquisition, exploration and development of natural resource properties thereby allowing for their participation
in larger programs, permitting involvement in a greater number of programs and reducing financial exposure in
respect of any one program. It may also occur that a particular company will assign all or a portion of its interest in a
particular program to another of these companies due to the financial position of the company making the
assignment. Under the laws of the Province of British Columbia, the directors of the Company are required to act
honestly, in good faith and in the best interests of the Company. In determining whether or not the Company will
participate in a particular program and the interest therein to be acquired by it, the directors will primarily consider
the degree of risk to which the Company may be exposed and its financial position at that time. See also “Describe the
Business - Risk Factors”.
