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.

2 - GENERAL DEVELOPMENT OF THE BUSINESS 

Capstone is a Canadian base metals mining company, focused on copper in the Americas.  We have grown through a 
combination of exploration, development and acquisition of mineral properties and currently operate three producing 
copper mines: Pinto Valley in the US, Cozamin in Mexico, and Minto in Canada. We have two development projects: Santo 
Domingo in Chile and Kutcho in Canada, as well as exploration properties in Chile, Mexico and Australia. 

2.1 

Three Year History 

2015 to date 

In February 2015 we announced the  selection of POSCO E&C (“POSCO”) as the preferred EPC  fixed price lump  sum 
contractor for the Santo Domingo project. While the final EPC contract has not been negotiated or concluded, we awarded 
POSCO a Limited Notice to Proceed (“LNTP”) to the end of Stage-Gate 1, which will include confirmation of completeness 
of the engineering and contractual performance guarantee parameters.  This award totaled approximately $4.5 million and 
is part of Capstone’s previously announced 2015 base case budget of $16.9 million (of which Capstone’s 70% share is $11.8 
million).  This work is expected to be completed before the end of the second quarter of 2015. 

In January 2015 we announced a Senior Secured Corporate Revolving Credit Facility ("RCF") for up to $500 million. This 
facility amended our existing senior secured corporate revolving term facility and allowed us to repay and cancel our senior 
secured reducing revolving credit facility. 

2014 

Following the acquisition of the Pinto Valley Mine in 2013, we issued a Pre-Feasibility Study in March of 2014 converting 
Mineral Resources to Mineral Reserves to take the mine plan from 5 years to 12 years, extending the mine life to 2026.  
Immediately  following  that,  a  further  study  was  undertaken  to  consider  the  remaining  Mineral  Resources  and  their 
potential.  At year end Capstone announced that two cases will be advanced to the pre-feasibility study level (“PV3 PFS”).   
The base case will include a 10% to 15% increase in throughput and the possibility of a mine life extension beyond 2026 
and a second case will evaluate a throughput increase to 90,000 tonnes per day combined with a potential mine life 
extension.  The PV3 PFS is expected to be completed in the third quarter of 2015, at which time we will evaluate the two 
alternatives and the best use of capital. 

Operating activities at the Pinto Valley Mine through the year focused on mill stability and cost reductions. Production was 
within the guided range for 2014 and nearing targeted operating levels by year end. 

In August, we announced completion of an updated NI 43-101 compliant mineral resource estimate for the Cozamin Mine 
in Mexico.  The estimate resulted in an immaterial reduction of both Mineral Reserves and Mineral Resources and a 
number of steps are now underway in early 2015 to potentially recover some reserve losses. 

On June 5, 2014 there was a fatality at the Cozamin Mine.  A contract miner was struck by a falling rock while working in an 
active mine face. 

At the Minto Mine in Yukon, the mine plan was revised during the year to reflect the delay in receiving the Water Use 
Licence (“WUL”) amendment which is required to bring additional reserves into the mine plan.  Capstone made application 
to the Yukon Environmental Socio-Economic Assessment Board ("YESAB") for all remaining identified copper reserves on 
the property in July 2013 and YESAB recommended in favour of the proposed continuation of operation of the Mine in 
April 2014. Application was then made for the amended Quartz Mining and Water Use Licences on July 2, 2014. We had 
three rounds of information requests from the Yukon Water Board through the latter part of 2014, with the Yukon Water 
Board declaring “Adequacy” in December 2014. On December 10, 2014, our application went to the public comment 
period, which ended on January 21, 2015. For an update on the status of the WUL amendment application please see the 
heading Minto Mine (Yukon) below.  

Development  activities continued to advance at our Santo Domingo project  in  Chile.   In June 2014  we completed  a 
feasibility study for the project with capital costs within the range of $1.7 billion as previously guided (accuracy range of -
10% to +15%) and an unlevered after-tax internal rate of return of 17.9%.  We continued to advance the regulatory, social 
licence and technical development of the project.   

 9 

 
A number of exploration activities were undertaken in 2014, both brownfield at our existing operation in Mexico and 
greenfield, primarily in Chile at Project Providencia, the earn in project with SQM.   

2013 

The most significant development in 2013 was our acquisition of the Pinto Valley Mine, which more than doubled our 
copper production. 

On April 28, 2013, we announced a definitive agreement with BHP Copper Inc., a subsidiary of BHP Billiton Ltd. (“BHP”), to 
purchase BHP’s wholly-owned Pinto Valley copper mining operation and associated SMARRCO in Arizona, US for $650M.  
The purchase price was paid in cash, satisfied from an existing $200M Senior Secured Revolving Credit Facility ($176M 
available at the time of the transaction), a new 2.5-year, $200M Senior Secured Reducing Revolving Credit Facility and cash 
on hand.  The acquisition was completed on October 11, 2013.  

The Pinto Valley property included a significant amount of mineralization not included in BHP's publicly-reported Mineral 
Reserve estimate. In conjunction with the acquisition, Capstone completed and filed a NI 43-101 report titled “Pinto Valley 
Property  Mineral  Resource  Estimate”  supporting  the  mineral  resource  estimate  of  the  Pinto  Valley  copper  mining 
operation. 

Development activities progressed at our Santo Domingo Project in Chile, with the Environmental Impact Assessment filed 
and the port concession advanced.  

Following the acquisition of Pinto Valley, Kutcho's production profile and mine life no longer fit within our growth strategy 
and we announced that strategic alternatives were being evaluated.  As such, the assets and liabilities of 
Kutcho are classified as held for sale as at December 31, 2014. 

Exploration activities advanced in 2013, both brownfield at our existing operation in Mexico and greenfield with the 
establishment of a significant new option agreement in Chile.  In March we announced an updated NI 43-101 compliant 
mineral resource estimate for the Mala Noche Footwall Zone (“MNFWZ”) at our Cozamin Mine in Mexico, updating the 
mineral resource estimate with drilling completed in the latter half of 2011 and most of 2012. 

In August, we announced an option agreement with SQM to earn up to 70% of a property, Project Providencia.  The initial 
option is on 350,000 hectares in Chile’s II Region and is reduced over time to a maximum of 50,000 hectares if a joint 
venture is formed.  Capstone is the operator of the project and have the right to withdraw from the project at any time.   

2012 

In 2012, we continued to advance on our organic growth strategy by completing the Phase VI Pre-Feasibility Study (“PFS”) 
on the Minto Mine.  This study built on the previous Phase V PFS by applying economic considerations to the most recently 
added resources and incorporating them into the mine plan, as well as optimizing, updating and improving on various 
other aspects of the operation.  This Phase VI PFS formed the basis to commence the permitting activities for the extended 
mine life. 

Following the Minto Phase VI PFS completion, additional drilling in 2012 continued to add to the Minto resource base with 
the first NI 43-101 compliant mineral resources estimate completed for two new areas, the Minto East Extension and 
Inferno North areas. 

Brownfield exploration activities continued at the Cozamin Mine, with an updated NI 43-101 compliant mineral resource 
estimate for the MNFWZ at the Cozamin Mine incorporating follow up drilling. 

In April 2012 we entered into a four year, $200M Senior Secured Revolving Corporate Credit Facility at US dollar London 
Inter-bank  Offered  Rates  (“LIBOR”)  plus  1.75%  with  four  banks.    This  facility  replaced  our  previous  $40M  corporate 
revolving term credit facility.  

On December 27, 2012, we announced a normal course issuer bid to purchase up to 34,014,871 of our common shares. 
Early in the first quarter of 2013, we purchased and cancelled 2,263,100 common shares in the open market.  The program 
was suspended as we advanced discussions on the Pinto Valley purchase.

3 - DESCRIPTION OF THE BUSINESS 

3.1 

General 

Capstone is a Canadian base metals mining company, focused on copper in politically safe and mining friendly jurisdictions 
in the Americas.  Our principal product is copper, with zinc, lead, molybdenum, silver and gold produced and sold as by-
products.  We are 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 and early stage exploration 
properties.  Capstone’s material mineral properties consist of: 

Pinto Valley Mine, an open-pit, copper mine located in Arizona, USA;  
Cozamin Mine, an underground, copper-silver mine located in the State of Zacatecas, Mexico; 

 
 
  Minto  Mine,  an  open-pit  and  underground  copper  mine  located  in  the  Whitehorse  Mining  District,  Yukon, 

Canada; and 
Santo Domingo Project, a large-scale, copper-iron project in Chile, in which Capstone holds a 70% interest.   

 

In addition to ongoing exploration at the Cozamin Mine aimed at increasing mine life and throughput, we have a portfolio 
of early-stage, base  metals  exploration projects  with 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. Capstone is actively pursuing additional exploration opportunities through earn-in 
and joint venture models. 

The primary exploration project we are presently pursuing is Project Providencia in Region II, Chile, under an option 
agreement with SQM to earn up to 70% of the project.  It is a very large under-explored land package in the world’s most 
prolific copper jurisdiction.

Principal Products and Operations  

The Company’s principal product is copper (in concentrate as well as copper cathode), with zinc, lead, molybdenum, silver 
and gold produced as by-product.  The following table summarizes Capstone’s production for 2013 and 2014: 

1 Pinto Valley’s results for the 82 day period of Capstone ownership (Oct 11/13 to Dec 31/13). 
2 Silver is not assayed on site for Pinto Valley, resulting in a significant lag time in receiving this data. 
3 Gold is not assayed on site for Minto, resulting in a significant lag time in receiving this data. 

During the year ended December 31, 2014, we generated gross revenue of $739.9M on the sale of 354,361 dmt of copper 
concentrates, 15,085 dmt of zinc concentrates, 2,083 dmt of lead concentrates, 166 dmt of molybdenum concentrates and

Precious Metals Streams 

In 2008, we sold all of our gold and silver production from the Minto Mine over the life of mine to Silverstone Resources 
(“Silverstone”), which was subsequently bought by 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.   We have recorded the proceeds received as deferred 
revenue and recognize this amount as an adjustment to revenue as the ounces are delivered. 

Under an April 2007 agreement we have committed to sell the Cozamin Mine’s silver production over a 10 year period to a 
company subsequently acquired by Silverstone, now Silver Wheaton.  Under that agreement, Silver Wheaton pays 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, we agreed to deliver a minimum of 10.0M ounces of silver under the Agreement. To December 31, 
2014  a  total  of  10.2M  ounces  have  been  delivered  against  the  contract,  thereby  surpassing  the  minimum  delivery 
requirement. 

Competitive Conditions  

Our business is to produce and sell copper.  Prices are determined by world markets over which we have no influence or 
control.  Our competitive position is primarily determined by our costs compared to other producers throughout the world 
and our ability to maintain our financial integrity through metal price cycles.  Costs are governed to a large extent by the 
location, grade and nature of our mineral reserves as well as by input costs and operating and management skills.  In 
contrast  with  diversified  mining  companies,  we  focus  on  copper  production,  development  and  exploration,  and  are 
therefore subject to unique competitive advantages and disadvantages related to the price of copper and to a lesser 
extent, the price of our base metal by-products.  If copper prices substantially increase, we 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, we will be at a competitive disadvantage to diversified mining 
companies. 

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

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 

 13 

 
 
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 our overall financial performance.  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. 

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 carrying out our business, nor should they result in an unsustainable 
burden on our earnings. 

Employees  

As of December 31, 2014, the Company had 1,345 employees and 475 contractors. 

Our workforce at Minto and Cozamin is not unionized.  There are approximately 368 hourly employees at the Pinto Valley 
Mine  who  are  members  of  six  unions,  governed  by  one  collective  bargaining  agreement  negotiated  by  the  United 
Steelworkers Union.  The collective bargaining agreement at the Pinto Valley mine expired in June 2014 and negotiations 
have been ongoing since that time. 

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.  We also have interests in 
various exploration projects in Chile, Mexico and Australia. 

Foreign operations accounted for approximately 79% of our 2014 revenue and represented approximately 83% of our 
assets as at December 31, 2014. 

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 was a fatality at the Cozamin Mine in June 2014.  A contract miner was struck by a falling rock while working in an 
active mine face underground. We reviewed safety practices at Cozamin and our other mine sites as part of company-wide 
due diligence and response to this incident.

Material Mineral Properties 

Pinto Valley Mine (US) 

The Company, through Pinto Valley Mining Corp., owns 100% of the Pinto Valley Mine, a 52,000 tonne per day copper 
mine located in the Globe-Miami district in Gila County, Arizona, approximately 130 km east of Phoenix in the southern 
United States.  Pinto Valley’s primary product is copper concentrate and we also produce copper cathode and by-product 
molybdenum and silver. 

The Pinto Valley Mine is the subject of a report titled “Pinto Valley Mine 2014 Pre-Feasibility Study” dated April 28, 2014 
with  an  effective  date  of  January  1,  2014  (“PV2  PFS”).    This  technical  report  was  compiled  by  Stantec  Consulting 
International LLC, and authored by Tony J. Freiman, PE, AMEC Environment & Infrastructure, Inc.; Corolla Hoag, CPG, SME-

Inc.; and John Marek, PE, SME-RM, Independent Mining Consultants, Inc., each a Qualified Person as defined by 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 PV2 PFS.  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 property is located at the west end of the Globe-Miami mining district, approximately 130 km east of Phoenix and 
10 km west of the town of Miami, in Gila County, Arizona, at 33°23’32”N and 100°58’15”W. The Pinto Valley property 
consists of approximately 2,460 ha of contiguous claims. These comprise 69 patented lode mining claims, 53 patented mill 
sites, 329 unpatented lode mining claims and mill sites, and seven parcels of fee (private) land. 

Capstone acquired the Pinto Valley Mine and associated railroad operations on October 11, 2013 for a cost of $650M USD.  
A 2% NSR applies to 26 of the unpatented mining claims which are not expected to be mined until after 2026. 

Pinto Valley is an open-pit operation that is currently 335 m deep, 1,500 m wide, and 2,100 m long. The pit is L-shaped and 
is near on-site infrastructure. There are suitable facilities for the maintenance of large earth-moving equipment and for the 
mill and general personnel.  Two previous tailings dams have been rehabilitated and two tailings dams are currently 
operational (Figure 1). 

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 strategy 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.  Surety Bonds 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 permitted mine plan on an undiscounted basis.  
These amounts are reviewed when we alert the agencies of a change in the mine plan or closure measures. 

The Pinto Valley Mine requires 17 permits granted from various state and federal agencies; operations of the railroad 
requires five permits mainly from the State of Arizona.  Pinto Valley Mine has all the necessary permits to conduct mining 
activities for the next 12 years, with the exception of an amendment to the Aquifer Protection Permit (“APP”) that is 
currently under review by the ADEQ and consolidation/renewal of existing land use authorizations (Plan of Operations) 
that is currently under review by the U.S. Forest Service (“USFS”).  After approval of the APP amendment and Plan of 
Operations, we expect that additional financial assurance will be required by the ADEQ and USFS, likely in 2015. 

Accessibility, Climate, Local Resources, Infrastructure and Physiography 

The Pinto Valley Mine is accessed from US Highway 60 (“US 60”), then 5 km on paved Forest Road (“FR”) 287.  The site can 
also be accessed from Tucson, Arizona (160 km to the south) by travelling north on State Route (“SR”) 77. The mine is 10 
km west of Miami, a town of approximately 1,800 residents, and 18 km west of Globe, the County seat, with approximately 
7,500 residents.  Because of a long-standing mining tradition in the area, many local services are in place to supply the 
mine's needs, with the remaining services coming from the greater Phoenix area.  Medical facilities are available in Miami.  
Fire, police, public works, transportation, and recreational facilities are in place and fully functioning.   

Pinto Valley Mine’s moderate, semi-arid regional climate allows for year-round operation. The average annual precipitation 
is 480 mm. May and June are typically the driest months of the year and may result in local drought conditions.  

Pinto Valley Mine has sufficient surface rights for mining operations, mineral processing facilities and tailings storage. 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.  Tailings Dam No. 4 is the primary storage facility, with Tailings Dam No. 3 used during 

 15 

 
maintenance activities at Tailings Dam No. 4 (Figure 1).  There is an adequate source of water with potable water coming 
from four groundwater wells and service water from a Peak Well system.

FIGURE 1: PINTO VALLEY INFRASTRUCTURE AND LOCATION OF OPEN PIT. 

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 is generally mountainous, dominated by sharp landforms and prolific exposures of  a 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 900 m to 1,500 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, with plant species on the property characteristic of each 
group.    Most  of  the  animal  species  observed  have  wide  environmental  tolerances  and  are  present  in  both  plant 
communities on the property. 

History 

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

The  Pinto  Valley Mine property was originally  owned by Miami  Copper Company in 1909 and transitioned, through 
acquisitions and mergers by the Tennessee Corporation and Cities Service Company, to Occidental Petroleum Corporation. 
Occidental sold the property to Newmont Mining Corporation in 1983, who changed the name to Pinto Valley Copper 
Corporation (“Pinto Valley Copper”).  In 1986, Pinto Valley Copper became the Pinto Valley Mining Division of Magma 

 16 

 
 
Copper Company. In 1995, Broken Hill Proprietary  Company Limited  purchased Magma  Copper Company, and after 
merging with Billiton in 2001, the Pinto Valley Mining Division became Pinto Valley Operations of BHP Copper Inc.  

A  chalcocite-enriched  zone  of  the  deposit  was  mined  from  1943  until  1953  as  the  Castle  Dome  underground  mine. 
Development of the Pinto Valley open pit began in 1972, with the mine and concentrator entering production in 1974 
producing a copper concentrate.  The solvent extraction/electrowinning (“SX/EW”) plant began processing pregnant-leach-
solution (“PLS”) from the leach dumps in 1981.  In February 1998, mining and milling were 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.  Cathode copper production continued during the suspension of sulphide operations at the Pinto 
Valley SX/EW facilities.  After a rehabilitation project, the mine and mill were restarted in late 2007. The Pinto Valley 
Operations operated for 18 months and was then again placed under care and maintenance in January 2009 due to 
depressed  metal  prices.    Operations  resumed  in  2012  by  BHP  Copper.    In  2013,  Capstone  purchased  Pinto  Valley 
Operations, now referred to as Pinto Valley Mine. 

The  pre-2006  Pinto  Valley  drilling  programs  comprised  a  combination  of  core,  rotary,  and  churn  drillholes.    Drilling 
documentation was limited to BHP Copper internal reports, and there were no listings for vintage data, methods used, or 
pre-2010 drilling procedures.  Churn holes defined much of the early Castle Dome mineralization, which has been mined 
out.  Post-Castle Dome holes were drilled on an original spacing of east-west and north-south.  Later, drilling was done to 
infill the original grid spacing in some areas.  Drilling that has occurred since the 1986 block model includes 10 core holes 
and 3 reverse circulation (“RC”) rotary holes drilled in 1992.  From the beginning of 1996 to April 1997, 67 RC exploration 
and infill holes were drilled: 48 RC holes drilled in 1996, and 19 RC holes drilled in 1997.  The 1997 holes 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.  All drillhole collar 
locations  were  surveyed.    The  majority  of  the  drillholes  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 were drilling 
campaigns with various purposes, including delineation, exploration, geotechnical, and resource classification upgrade 
drilling.  These include 39 drillholes in 2007 and 62 drillholes in 2008.  Diamond drillhole programs in 2010 focused on 
exploration,  while  those  in  2011  and  2012  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.  In 
2013 BHP drilled 12 in-pit infill diamond drillholes totalling 2,853 m, to close the drillhole spacing grid and 64 in-pit RC 
drillholes totalling 3,380 m to help characterize the mineralization directly beneath working levels of the mine. 

All drillhole logging data, including collar, survey, assay, lithology, alteration, and mineralization data were entered into an 
acQuire™ structured-query-language (“SQL”) database system.  All sample data were tagged and tracked using bar codes, 
which linked all assay information provided by the laboratory to the database, including the QAQC.  The system was 
secured by BHP using stringent protocols and procedures.  Deviations and discrepancies from sample dispatch reports 
were reported and investigated.   

A number of different companies and laboratories 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 were in line with industry 
standards  for  total  copper  analyses,  but  BHP-specific  procedures  were  used  to  determine  acid  soluble  copper 
concentrations.  These involved digestion with 10% sulphuric acid, followed by placement in a hot bath at 40°C, and read 
after 40 minutes. 

Independent audits of the Pinto Valley assays were conducted in 1992 and 2000.  Results indicated the assay values in the 
Pinto  Valley  database  have  been  reliably  entered  and  that  total  copper  assays  in  the  Pinto  Valley  database  were 
reproducible and could be considered representative within normally-accepted error limits.   

As part of the start-up Feasibility Study done in 2006, a QAQC program was conducted on 101 randomly selected drillhole 
assay interval pulp samples and 15 randomly selected drill core assay intervals.  Samples were sent to Skyline Assayers and 
Laboratories (“Skyline Labs”) in Tucson, Arizona for total copper and acid-soluble copper analyses.  Skyline Labs was 
instructed to analyse the samples for acid soluble copper using BHP lab procedures.  Certified reference material standards 

 17 

 
from the National Institute of Standards and Technology (“NIST”) were inserted in sequential order for analysis preceding 
the 15th pulp sample in the analytical run.  The results indicated that historical quality control measures used in the Pinto 
Valley Mine analytical laboratory were variable.  At times they were extremely good, but at others they were less so, 
although still acceptable.   

BHP Copper undertook surface mapping to provide additional data throughout the identification and selection phases of 
the PV2 mine planning project.  Two  drilling  campaigns were conducted on separate occasions to improve both the 
geotechnical and geometallurgical knowledge of the deposit.  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 most important 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).  
Capstone relied extensively on the BHP Copper’s PV2 project data to complete the Capstone PV2 PFS.  The data provided 
by BHP Copper was reviewed by the QPs in the Capstone PV2 PFS to ensure it was applicable and sufficiently detailed to 
form the basis of assumptions in the study.  Additional work was conducted where data gaps were found, including field 
mapping for pit wall geotechnical analysis, geotechnical drilling for tailings impoundment design and metallurgical testing 
to validate previous test results.   

Geological Setting 

The Globe-Miami mining district of central Arizona includes porphyry copper-molybdenum (“Cu-Mo”) deposits associated 
with Paleocene Epoch granodiorite to granite porphyry stocks (65-59 million years ago).  Vein deposits and possible exotic 
copper deposits are also found within the district.   

Precambrian basement rocks throughout southern Arizona and New Mexico largely consist of early Proterozoic Pinal schist 
(~1,700 million years old) intruded by granites correlative with 1,450 Ma two-mica granite batholiths.  At the Pinto Valley 
Mine this is represented by the Ruin granite (also referred to as the Lost Gulch quartz monzonite) that hosts the Cu-Mo 
mineralization.  The Late Proterozoic-aged (~1,420-1,150 million years old) Apache group, comprising conglomerate, 
limestone, quartzite, and minor basalt units overlying the basement rocks, was intruded by 1,150 million years old Apache 
diabase sills of varying thicknesses.  These diabase units are represented at the Pinto Valley Mine as thin dikes and sills, 
and commonly contain higher copper concentrations than the surrounding Ruin granite. During the Paleozoic Era, various 
limestone units were deposited representing the shallow, marine environment present over much of the southwestern US 
at the time. 

Subduction of the Farallon tectonic plate (80-50 million years ago) off the west coast of the southwestern US initiated arc 
magmatism responsible for generating the Cu-Mo-bearing intrusions in the region. Stocks emanating from the Schultze 
granite, the source of the mineral-bearing fluids to the Globe-Miami district, were emplaced at the Pinto Valley Mine 
between 60-59 million years ago.  

Regional  Tertiary-Era  Basin  and  Range  extension  and  faulting  following  cessation  of  subduction  facilitated  the 
dismemberment, tilting, and exposure of the Cu-Mo deposits.  They were preserved through deposition of the Whitetail 
conglomerate (Oligocene Epoch) and the Apache Leap tuff (Miocene Epoch).  Further extension in the Pliocene Epoch 
deposited the Gila conglomerate into basins. 

The Pinto Valley Mine deposit is bound by faults that vary in age from the Pre-Cambrian to the Tertiary. These have 
controlled the emplacement of the Ruin granite, stocks of the Cu-Mo-bearing Schultze granite, and subsequent post-
mineralization Basin-and-Range extensional faulting.   

Exploration 

Capstone is not currently exploring the Pinto Valley Property because only 16% of the known mineral resources are 
included in the mineral reserves. We are focused on increasing mineral reserves through engineering, feasibility and 
permitting work aimed at demonstrating economic viability of the existing mineral resources not presently included in the 
mineral reserves.  

 18 

 
Mineralization 

The  primary  sulphide  minerals  encountered  at  the  Pinto  Valley  Mine  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.  Alteration of silicate minerals of the host rocks to other groups of minerals due to the presence of hydrothermal 
fluids associated with the Cu-Mo-bearing intrusive rocks include potassic, argillic, sericitic, and propylitic alteration suites. 

Sulphide minerals generally 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.    Molybdenum 
distribution generally reflects copper distribution, with higher molybdenum values usually found in the higher grade 
copper zones. Oxide mineralization and a supergene enrichment blanket was developed at the Pinto Valley Mine, but these 
areas have since been mined. 

Sulphide deposition at Pinto Valley is controlled to some extent by the host rock.  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.   

Drilling 

We have not conducted any exploration drilling programs since taking ownership of the Pinto Valley Mine.  We continue to 
focus on increasing the mineral reserves through engineering, feasibility, and permitting work aimed at demonstrating 
economic viability of the existing mineral resources not in the mineral reserves. 

Sampling and Analysis 

The Company has not undertaken any drilling or exploration work since acquiring the Pinto Valley Mine.  Details pertaining 
to sampling during drilling programs completed before Capstone ownership can be found above in the section titled 
History.  

As a part of the data verification process, Garth Kirkham, P.Geo, an independent Qualified Person as defined by NI 43-101 
and co-author of the NI 43-101 Technical Report, Pinto Valley Mine 2014 Prefeasibility Study, visited the property on May 
14, 2013.  He inspected the core logging facilities, offices, outcrops, historic drill collars, core stage facilities, core receiving 
area, core sawing stations, and toured 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.   

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

Mr. Kirkham was confident the data and results were valid based on the site visit and inspection of all aspects of the 
project.  This confidence extended to the sampling methods and procedures used.  In Mr. Kirkham’s opinion, all work, 
procedures and results have adhered to best practices and industry standards required by NI 43-101.  Mr. Kirkham also 
visited Skyline and deemed the lab to be professionally operated, as is expected from a widely-used North American 
laboratory facility.  Skyline has been ISO 17025 certified since 2008. 

Mineral Resource and Mineral Reserve Estimates 

The mineral resource estimate for Pinto Valley mineralization was completed by independent consultant and Qualified 
Person, Garth Kirkham, P.Geo., of Kirkham Geosystems Ltd., as a part of the PV2 PFS summarized in the Pinto Valley Mine 
2014 Prefeasibility Study NI 43-101 Technical Report.  The mineral resources were estimated using accepted industry 
standards conforming to NI 43-101 requirements.  Drillhole samples were composited downhole to 13 m (45 feet) length 

 19 

 
to match the selective mining unit (“SMU”) bench height and to reduce the influence of typically narrow, very high-grade 
samples.  A radius of 45 m has been applied to values greater than 1.5% total copper (“TCu”) and 0.05% molybdenum 
(“Mo”).  The average bulk dry density for ore-grade mineralized rock, primarily Ruin Granite, is 2.51 t/m3 (12.75 ft3/ton).  
Although the in-situ bulk dry densities for all Pinto Valley Mine rock types range between 2.46 t/m3 (13.0 ft3/ton) for 
Whitetail conglomerate to 2.64 t/m3 (12.1 ft3/ton) for Pinal schist, 12.75 ft3/ton was used.  Grade variability is low, with 
nugget effects of less than 15% for both copper and molybdenum.  The block model grades for copper and molybdenum 
were estimated using ordinary kriging into blocks that were 30 m Easting × 30 m Northing × 14 m Elevation (100 ft × 100 ft 
×  45 ft)  in  size.    During  grade  estimation,  search  orientations  were  designed  to  follow  the  general  trend  of  the 
mineralization in each of the zone domains.  The estimation plan involved a single search pass using a minimum of 6 
composites and a maximum of 15 composites, with a maximum of 5 from any single drillhole.  The search ellipse measured 
230 m along the major and semi-major axis and 90 m along the minor axis. 

In 2014, a refined topographic surface was generated to report the mineral resources within the floating cone pit-shell 
described in the PV2 PFS.  The refined topographic surface resulted in an increase to the reported Measured and Indicated 
mineral resources by 59,991 kt at an average grade of 0.35% Cu and Inferred mineral resources by 461 kt at a grade of 
0.31%  Cu, all above a  0.18%  Cu  cut-off  grade.  The  reported  mineral resources in  Table  1 are  based on the mineral 
resources  estimate  completed  by  Garth  Kirkham,  P.Geo.,  that  reflect  the  refined  topographic  surface.    The  mineral 
resources have been updated to take into account mining activities until December 31, 2014 by Pinto Valley Mine staff 
under the supervision of Jeremy Vincent, P.Geo., Manager of Production and Development Geology at Capstone, and a 
Qualified Person under NI 43-101.  Mineral resources are reported above a 0.18% Cu cut-off grade.

The mineral reserves estimate, completed by John Marek, PE, President of Independent Mining Consultants, Inc., (“IMC”), 
was developed by tabulating the contained Proven and Probable-classified material inside of the designed open pit above 
the mill cut-off grades.  Property boundaries and the capacity of permitted tailings facilities constrained the mineral 
reserves.  The mine plan and schedule utilize a declining cut-off grade to the mill that starts at breakeven cut-off in 2014 
and reduces to internal cut-off in 2023.  Based on a long-term copper metal price of US$2.20/lb for a floating cone pit 
optimization analysis, the cut-off grade for the estimation of mineral reserves is 0.18% TCu for production years 2014 
through 2022.  This is the low-grade stockpile cut-off.  The remaining years of the mine life, 2023 through 2025, utilize a 
0.17% TCu cut-off grade.  The final pit design has not included the run-of-mine (“ROM”) dump leach in the floating-cone 
pit-optimization analysis.  Material that is incurred at ROM leach grade is reported in the mining plan for allocation to 
storage areas, but it is not incorporated into the statement of mineral reserves.  The mineral reserves stated in Table 2 are 
based on the mineral reserves estimate completed by John Marek, PE.  This has been updated by Pinto Valley Mine staff to 
reflect mining activities until December 31, 2014 under the supervision of Brad Skeeles, Vice President of North American 
Operations for Capstone, a Qualified Person as defined by NI 43-101.

Mining Operations 

Pinto Valley copper mine is an open-pit mine with conventional processing facilities and an SX/EW plant for low-grade 
copper extraction.  The Pinto Valley Mine, which restarted in December 2012, uses a conventional drill and blast, and truck 
and shovel fleet.  The pit is mined in 14 m benches with a double bench configuration in deeper zones.  Material from the 
pit is transported to either the primary crusher, run-of mine stockpile, waste rock dumps or low-grade leach dumps.  

Run of mine ore is crushed through the primary crusher and conveyed to the fine crushing plant for further size reduction.  
The fine-crushed ore is fed to a conventional grinding and flotations circuit to produce a bulk copper concentrate and 
molybdenum concentrate.  The concentrates are thickened and filtered to produce product suitable for transport.  The 
product is transported by truck to SMARRCO, a trans-shipment facility in San Manuel, Arizona where it is transported to 
Port of Guaymas, Sonora, Mexico by rail.  The concentrate is loaded onto ocean freighters for delivery to international 
market.  Low-grade leach-dump material goes through a leach processing and the resulting pregnant leach solution is sent 
to the SX/EW facility to create copper cathodes.   

The majority of copper concentrate produced from Pinto Valley is sold to smelters under multi-year contracts.  The copper 
cathode is sold through a competitive tendering process. Pinto Valley has a processing rate of 50,200 tpd and life of mine 
annual production of 54,200 kt of copper contained in concentrate and 2,860 kt of cathode copper.  The current mine 
plans extends the Pinto Valley Mine operations life to 2026. 

Pinto Valley has well-established environmental protocols that adhere to federal and state regulatory requirements and to 
internal corporate guidance to reduce impacts to the environment.  Pinto Valley is subject to environmental regulations 
addressing groundwater, surface water, storm water management; air quality; well installation; water withdrawal from 
state aquifers; waste handling and disposal; handling and storage of toxic substances; surface reclamation; and cultural 
and biological resources.  The Pinto Valley Mine has all the necessary permits to conduct mining activities through 2026, 
with the exception of the consolidated Plan of Operations that is currently under review by the USFS.  The consolidated 
Plan of Operations is a compilation of prior authorizations and encroachments on federal lands and is expected to be 
completed in 2016.

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 
36.35% 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. 

The economic analysis was conducted for Pinto Valley as part of the PV2 PFS.  The cash flow analysis shows an operating 
cash flow of $1,602 M, which results in a pre-tax NPV (8%) of $931M and a post-tax (8%) of $738M. The analysis did not 
include any acquisition cost or expenditures prior to January 1, 2014 and treated those costs as “sunk”. 

Exploration and Development 

We do not currently have any planned exploration activities at the Pinto Valley Mine.  Our development activities are 
focused on  PV2 execution  with  the arrival of additional  mining equipment. An  internal study in  2014 evaluated the 
resources at Pinto  Valley not included in the current  mine plan. As a  result, two  cases  will be advanced to the  Pre-
Feasibility study level (“PV3 PFS”). The PV3 PFS base case will include a 10% to 15% increase in throughput and the 
possibility of a mine life extension beyond 2026 and a second case will evaluate a throughput increase to 90,000 tonnes 
per day combined with a potential mine life extension. The PV3 PFS is expected to be completed in the third quarter of 
2015, at which time we will evaluate the two alternatives and the best use of capital. 

Cozamin Mine (Mexico)

Project Description and Location 

The Cozamin Mine is a 3,300 tonne per day operating copper-silver mine, 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 Mine comprises 88 concessions covering 
approximately 4,308 ha.  

The Company acquired the project in January 2004, which is 100% owned by the Company, subject to a 3% NSR payable to 
Grupo Bacis S.A. de C.V., a Mexican resource company.  Mineral claims acquired in September 2009 from Minera Largo S 
de RL de CV, a wholly owned subsidiary of Golden Minerals Company (“Golden Minerals”),  are subject to future cash 
payments of a NSR of 1.5% on the first one million tonnes of production and 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.  In 2014, we 
acquired 45 additional concessions from Golden Minerals totalling 775 ha that surround the Cozamin Mine’s existing 

 22 

 
concessions.  A total of 17 of the claims are subject to a finder’s fee to be paid as a 1.0% NSR or Gross Proceeds Royalty to 
International Mineral Development and Exploration Inc. pursuant to existing agreements on the concessions dating back to 
October 1994 and August 2000.  The Cozamin property requires land rental and government fee payments on the mining 
concessions to be paid semi-annually in January and July. Taxes totalled US$ 34,810 in 2013 and US$ 41,945 in 2014. 

The Cozamin Mine lies within a regionally mineralized area that has seen extensive historic mining over more than 475 
years.  Host rocks surrounding the mineralized vein systems are anomalous in base and precious metals, providing a halo of 
elevated metals values that extends a considerable distance beyond the known workings.  Numerous old mine workings, 
excavations and dumps, as well as some historic tailings are present, both on, and adjacent to, the Cozamin mine site; 
some lie on mining lands held by Capstone and others are held by third parties.   

Prior to the Company’s involvement in the Cozamin Mine, several environmental studies had been carried out by previous 
owners.  The San Roberto Mine had previously been fully permitted to operate at 750 tonnes per day (“tpd”).  Capstone 
formally received its operating permit on October 20, 2006.  This is known in Mexico as a Licencia Ambiental Única (“LAU”).  
A LAU for a throughput expansion to 2,600 tpd was received on March 25, 2008.  On January 19, 2009, application was 
made to modify the LAU to expand throughput 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.  We expect to receive a permit in 2015 to operate at throughput up to 4,500 tpd capacity. 

The Cozamin Mine’s mineral resources and mineral reserves are situated primarily within a mineralized vein/fault structure 
known as the Mala Noche Vein (“MNV”) that strikes east-west and dips to the north.  This structure hosts the copper-rich 
San Roberto Mine and adjacent to the east, the zinc-rich San Rafael Mine. In 2010, we discovered the Mala Noche Footwall 
Zone (“MNFWZ”), a vein splay oriented northwest-southeast off the MNV.  The Company is currently exploring veins and 
fault splays analogous to the MNFW.  Figure 2 illustrates the location of project infrastructure and the surface projection of 
the MNV. 

FIGURE 2: COZAMIN INFRASTRUCTURE AND LOCATION OF MINERAL RESOURCES AND RESERVES. 

Environmental studies have shown that flotation tailings and some types of waste rock have the potential to generate 
acidic drainage.  However, the country rocks surrounding the deposit have significant neutralizing capacity and show 
relatively low permeability.  In addition, construction activities as a part of the expansions have already reduced identified 
sources of acidic drainage associated with the historic tailings impoundment as well as downstream contamination due to 
tailings spills by previous operators.  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 

 23 

 
 
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.  Cozamin was awarded the Clean Industry Certification from Mexico’s Federal 
Attorney for Environmental Protection (Procuraduría Federal de Protección al Ambiente or PROFEPA) for the second time 
in December 2013 for this management process and best practices and procedures.  This is valid until November 2015. 

Accessibility, Climate, Local Resources, Infrastructure and Physiography 

The Cozamin Mine is located 3.6 km to the north-northwest 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 Hacienda Nueva (3 km west), Morelos (5 km northwest) and Veta Grande (5 km north).  The Cozamin 
Mine operates year round and 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 mine area falls within the Hacienda Nueva and La 
Pimienta Ejidos. 

The Cozamin Mine has excellent surrounding infrastructure including schools, hospitals, railroads, highways, and electrical 
power.  The mine has access to a power line and substation that allows the Company to draw up to 10.5 MW from the 
national power grid.  Generators (both operating and back-up) on site have a capacity of 2.0 MW.  At present there is 
sufficient capacity to store all of the tailings from the processing of identified mineral reserves assuming the Stages 6 and 7 
lifts are constructed.  Permits are not currently issued for all of these additional raises to the tailings storage facility.  
Employees and contractors are sourced from Zacatecas and other nearby communities with minimal foreign staff at the 
mine.  Sufficient surface rights have been obtained to conduct all mining operations. 

The  climate  in  the  region  is  semi-arid  with  maximum  temperatures  of  approximately  30°C  during  the  summer  and 
minimum temperatures in the winter producing freezing conditions and occasional snow.  The rainy season extends from 
June until September, with average annual precipitation totalling 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 northwest 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.  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  people who  mined native  silver from the oxidized  zone of 
argentiferous vein deposits in the Zacatecas Mining District.  During the Spanish Colonial era production commenced in 
1548 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 oxide minerals for silver and some gold, and later the 
sulphide-mineral zones were worked for base and precious metals. 

From 1972, Consejo de Recursos Minerales (“CRM”) worked mines in El Bote, La Purisima and La Valencia zones.  A number 
of old workings are located throughout the mine area, but accurate records of early production are not available. 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 much of the Mala 
Noche Vein and operated the San Roberto Mine and plant at 250 tpd until October 1996.  During this period, Industrias 

 24 

 
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 to Minera Argenta, a subsidiary of Minera Bacis S.A. de C.V. (“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, mainly from shallow, oxide zone workings.  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.  Near the 
end of 1998, Bacis closed the mine primarily due to low metal prices and under-capitalization of the asset.  Capstone 
assumed ownership of the Cozamin Mine in 2004. 

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 of Tertiary Era age, and are interpreted to be related to the development of a volcanic centre 
and to northerly trending basin-and-range structures.  It occurs in a structurally complex setting, associated with siliceous 
subvolcanic and volcanic rocks underlain by sedimentary and meta-sedimentary rocks.  The geologic units in this area 
include Triassic-aged metamorphic rocks of the Zacatecas Formation and overlying basic volcanic rocks of the Upper 
Jurassic-aged or Lower Cretaceous-aged Chilitos Formation.  The Tertiary rocks consists mainly of a red conglomerate unit 
deposited in the Paleocene Epoch and/or Eocene Epoch, and overlying rhyolitic tuff and intercalated flows that were 
deposited from Eocene to Oligocene Epochs.  Some Tertiary Era rhyolite bodies cut the Mesozoic Era and Tertiary Era units 
and have the appearance of flow domes. 

The host rocks for the MNV are intercalated carbonaceous meta-sedimentary rocks and andesitic volcanic rocks ranging in 
age from Triassic to Cretaceous, and Tertiary-aged rhyolite intrusive rocks and flows.  Mineralization in the MNV appears to 
have been episodic.  A copper-silver dominant phase is interpreted as 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. 

Exploration 

Cozamin exploration geologists have systematically mapped a total of 1,694 ha throughout the Cozamin Mine property at 
scales of 1:1,000 or 1:2,000 since 2004.  Regular surface exploration along the strike of the MNV system has occurred 
through channel sampling and chip sampling.  Channel samples were cut perpendicular to the strike of the vein and 
weighed approximately 2 kg.  The results of the surface channel and chip sampling programs have been used to assist with 
exploration drillhole planning, but not used for mineral resources estimation.   

We  undertook  several  geophysical  surveys  using  contractors  between  2004  and  2010.    A  ground  magnetic  survey 
completed by Zonge Engineering and Research Organization (“Zonge”) in 2004 collected total magnetic field data from 24 
north-oriented lines spaced 25 m apart that permitted mapping of the linear east-west orientation of the Mala Noche 
system as well as other intrusive features.  Also in 2004, Zonge undertook a resistivity study through measurement of 
magnetic response using Controlled Source Audio Magnetotellurics over 8 line-kilometres and Natural Source Audio 
Magnetotellurics over 16 line-kilometres indicated the presence of sulphide mineralization below known mineralized 
extents.  These results were used to assist with exploration drillhole planning.  During the summer of 2009 New Sense 
Geophysics Limited conducted an aeromagnetic survey over all of the Cozamin Mine concessions.  The results revealed a 
broad magnetic high trending northwest.  These data were later reprocessed in 2013 and used for tracking infrastructure 
such as power lines and pipe lines and the general structural and vein trends of the Mala Noche system.  In some cases the 
data were used as a secondary tool to help guide exploration and drill planning in new target areas.  Between October 
2009 and January 2010 Zonge completed resistivity and ground-induced polarization studies centred over Mala Noche 
West, Hacienda Nueva South, Mala Noche North, and Mala Noche East.  Identified anomalies were followed up by drilling, 
but the results were poor.  The presence of sulphide-rich and graphitic sedimentary rocks coupled with widespread sources 
of cultural likely precluded effective chargeability, resistivity, or conductivity surveys, and as such we have not explored 
using geophysical methods since 2010. 

 25 

 
Mineralization 

All mineralization at the Cozamin Mine occurs primarily in the Mala Noche fault-vein structure (“MNV”).  In the San 
Roberto Mine, the Mala Noche strikes west-northwest and the dip varies between 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. 

The main stage of copper-dominant 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 or overprint earlier more clearly epithermal zinc-dominant mineralization.  The 
epithermal veins display well banded quartz veins, sulphide pseudomorphs of carbonates, 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.   

Pyrite is the dominant vein sulphide and typically comprises approximately 15% of the MNV in the San Roberto mine.  
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.  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.    Argentiferous  (silver-bearing)  galena  is  less  common  than  sphalerite  but  is generally  associated  with  it  as 
crystalline replacement masses.  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.  
Gangue minerals in the MNV consist of quartz, silica, calcite, chlorite, epidote and minor disseminated sericite.  The quartz 
occurs as coarse grained druse coarse crystalline masses, and a stockwork of quartz veinlets.   

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.  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.  The vertical extent of mineralization at San Roberto is over 820 m.  Adjacent to the San Roberto mine is 
the San Rafael mine, a zinc-rich part of the deposit with the same epithermal mineralization characteristics as the San 
Roberto mine.  The MNFW zone, a splay off the MNV discovered in 2010, is not exposed at surface; however, based on 
underground drilling it strikes in a northwest-southeast orientation over 1.45 km and dips on average 54° to the northeast. 
Known mineralization here has a vertical extent of approximately 500 m.  The MNFW zone comprises up to five veins in 
close special association with rhyolite dikes and locally cross-cut the intrusions themselves.  The relative age of the copper 
mineralization ranges from contemporaneous, to post-rhyolite magmatism. 

Drilling 

In all, 618 diamond drillholes of HQ and/or NQ diameter have been completed from surface and from  underground 
locations at the Cozamin Mine since April 2004.  A total of 11 phases of drilling have targeted resource definition and 
expansion  along  the  MNV  (San  Roberto  and  San  Rafael  mines),  MNFW  zone  (since  discovery  in  2010),  and  other 
exploration targets on our property.  

Drillhole collars are located using a total station TRIMBLE instrument, model S6.  Downhole 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 were corrected for magnetic 
declination. 

In the core logging facility drillholes are assessed for drilling recovery, which has historically been very good.  Drillholes are 
then logged for geology, alteration and mineralogy, followed by structural data measurements and rock quality (RQD) 

 26 

 
assessment.  Next, the drillholes are marked for sampling by the geologist. This is followed by core photography before the 
core is sent for splitting.   

Sampling and Analysis  

We use diamond drillcore samples and underground mine-production chip-channel samples (“CCS”) for mineral resources 
estimates.    Diamond  drillholes  intersecting  the  MNV  are  spaced  approximately  60 m  along  strike  and  down  dip.  
Mineralization is less continuous in the MNFW zone than in the MNV, thus drillholes are more closely spaced averaging 
approximately 50 m along strike and down dip.  Capstone employees are responsible for the all on-site sampling of drill 
core.  The entire vein width is sampled.  Typical sample intervals for drillcore are 0.5 m in the vein and 2 m in the wallrock 
(waste).  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).  Samples are split by core saw and placed 
in marked bags and shipped to accredited external laboratories for sample preparation and analysis for copper, lead, zinc, 
silver, and sometimes gold.  There were a total of 43,935 diamond drillhole samples contained in the database used for the 
March 2014 mineral resources estimate.  Capstone employees are responsible for the all on-site sampling of drill core.   

Sample quality of drillhole samples is monitored through regular insertion of reference material standards, blanks, and 
duplicate samples.  Between 2010 and 2013 reference material standards were created using MNV material, homogenized, 
and sent for round robin analysis at external laboratories.  Accuracy control was generally good for copper, but there were 
periods of high failure rates for silver, zinc, and lead that suggested the reference material was insufficiently homogenized.  
Medium and high grade drillhole samples were not supported by reference material standards between 2012 and 2013.  
These results triggered an audit of our quality assurance/quality control (“QAQC”) program in 2014 and we concluded it 
had not been effectively or consistently implemented since 2010.  The use of non-certified reference material standards 
impacted the Cozamin Mine’s ability to assess laboratory performance.  In addition, sample failures were not addressed.  
We  took  immediate  corrective  measures  by  purchasing  certified  reference  material  standards,  updating  our  QAQC 
procedures to include real-time monitoring of quality control data, setting thresholds for sample failures and sample batch 
reanalysis, and regular monthly reporting.   

Furthermore,  in  June  2014  we  commenced  a  resampling  program  of  all  pulps  and  drillcore  within  the  mineralized 
intercepts of the San Roberto and MNFW zones in order to provide stronger analytical control over the samples.  These 
were submitted to external laboratories along with purchased certified reference material standards. At the time of the 
August 2014 Cozamin NI 43-101 Technical Report, we had received the results from all pulp samples and a portion of the 
drillcore samples. As reported, the pulp samples showed very strong correlation between the reanalyzed values and the 
original values for copper, good correlation for lead and zinc, and fair correlation for silver and gold.  Results for the 
remaining drillcore samples were received by October 2014.  The assay values for the remaining half of the core showed 
high levels of scatter, with many samples plotting outside of tolerance thresholds.  Allowing for variation due to movement 
of core within the core boxes, minor  core degradation, and variability due to different  digestion methods,  Capstone 
considers the results to still be acceptable, as overall correlation values are good and there is minimal bias evident.  The 
reanalysis program process was demonstrated to be accurate and representative through the QAQC control samples, 
including purchased certified reference material to verify analytical accuracy, insertion of blanks to evaluate between-
sample contamination, and duplicates of pulp reject and coarse reject material to ensure sample preparation produced a 
representative sub-sample. 

Underground CCS samples are marked out by the geologist.  Samples are oriented perpendicular to the strike of the vein 
and are extracted using a hammer and chisel.  They weigh approximately 2 kg.  We note that chip-channel samples do not 
yield truly representative samples due to sample delimitation and extraction errors that are unavoidable during sampling.  
Sample spacing along the strike of the vein is about 4 m.  There were a total of 54,666 CCS samples contained in the 
database used for the March 2014 mineral resources estimate.  All underground CCS samples are sent to the Cozamin mine 
laboratory (“CML”) that is ISO/IEC 17025:2005 accredited for volumetric determination of copper, zinc and lead.  The audit 
of our QAQC program also showed periods of high sample failure rates and that QAQC sample failures were not addressed.  
In addition, QC sample submission rates across low, medium, and high grade ranges were inconsistent.  The same QAQC 
corrective measures implemented for our diamond drillhole samples were carried over to the underground CCS samples.   

A bias analysis between diamond drillhole and CCS samples located within the mineralized structures was completed as a 
part  of the March 2014 resource update.  Channel samples were found to be consistently higher than the diamond 

 27 

 
drillhole samples.  This was taken into account during grade estimation by restricting the search ellipse size during the first 
estimation pass to limit the influence of CCS  samples on  more distant  blocks.   Further grade-bias analysis has been 
recommended before another resource updated is completed.  No other drilling, sampling, or recovery factors have been 
identified that could materially impact the accuracy or reliability of the results. 

The  Cozamin  Mine  collects  bulk  density  measurements  from  mineralized  and  non-mineralized  intercepts  from  each 
drillhole.  All drillcore pieces greater than 10 cm in length within an assay sample length are selected from the core box and 
measured using a weight-in-air weight-in-water technique.  A review of these data highlighted widely ranging values, which 
were reanalysed as a part of a quality control check.  In November 2013, a QAQC program was implemented to monitor 
bulk  density  measurements.    The  QAQC  samples  (duplicate  measurements  and  analysis  of  a  bulk  density  standard) 
indicated the bulk density dataset was of sufficient quality for use in mineral resource and reserve estimation.  There were 
a total of 15,304 bulk density measurements used to estimate density in the mineral resource estimate. 

In 2014, our drillhole and CCS databases failed audits checking the stored information against the original data sources 
(assay certificates, downhole survey logs, and collar coordinate records).  Many of the errors were due to “copy and paste” 
mistakes into Microsoft Excel™ spreadsheets that had been used to store our drillhole and CCS data.  These errors were 
corrected, and in October 2014, we completed an installation of an acQuire™ structured-query-language-based (“SQL”) 
database to store and validate our drilling and sampling data.  SQL databases are recognized as an industry standard for 
storage and safeguarding of geological data.  We will be completing a check of 10% of our diamond drillhole and CCS data 
as a final validation step of the acQuire installation process in the first quarter of 2015.   

Other data checks included validations of the spatial locations of mineralized drillhole intercepts and the locations of CCS 
data with respect to underground mapped geology.  Errors were noted and corrected.  There are 122 drillholes whose 
intercepts did not align with the mapped location of the mineralized zones underground.  This likely due to small errors in 
the  collar  locations  or  insufficient  downhole  survey  readings.    These  drillholes  were  excluded  from  the  geological 
interpretation and from use in mineral resources estimation.   

Security of Samples 

Only employees of Capstone entities are permitted in the core shack when unsampled drillcore is ready to be cut.  A 
minimum  of  10  samples  are  placed  in  a  large  sack  and  secured  by  a  tamper  proof  seal.    A  transmittal  form  is  then 
completed, which identifies the batch number, the serial numbers of the seals and the corresponding sample number 
series, and delivered to the sample preparation laboratory by a Cozamin representative.  

Drill  core  containing  intercepts  of  the  Mala  Noche  Vein  and  Mala  Noche  Footwall  structure  is  stored  in  a  secured 
warehouse near the core shack.  Waste hangingwall and footwall drill core is stored within the mine on Level 8 to conserve 
space in the warehouse.  Access to the warehouse is controlled by the Geology department.  No person other than the 
geologist responsible for logging is allowed to handle the core prior to sampling.   

Mineral Resource and Mineral Reserve Estimates 

The  March  2014  mineral  resources  estimate  for  San  Roberto  and  Mala  Noche  Footwall  zones  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 geological wireframe solids were created 
from cross-sectional interpretations and compared to level plans of underground mapped geology. The interpretations 
were snapped to drillholes to ensure  correct sample  selection during coding and grade estimation.   The veins  were 
modelled as grade shells using copper grades to determine the limits of mineralization above a 0.5% copper cut-off, with 
local allowances made based on geology and zinc concentrations.  Two methods were employed to handle outlier grades 
during grade estimation. Sample outliers reviewed and set to the defined high grade limit before compositing, and the 
range of outlier composite grades were restricted during grade estimation.  Samples were composited downhole to 1.5 m 
lengths.  Spatial analysis of grade data was undertaken using correlograms.  Grades were estimated by ordinary kriging 
using three search passes into blocks sized 10 m Easting × 10 m Northing × 12 m elevation.  Search ellipses were oriented 
to match vein orientations.  Model validation included visual inspection of estimated grades in comparison to sample 
composites, creation of swath plots along easting, northing, and elevation sections to assess grade smoothing, as well as 
evaluation of the grade-tonnage curves with respect to theoretical predicted results (referred to as a global change of 
support).  The validation checks showed the models to be valid with appropriate levels of smoothing.  As a result of the 

 28 

 
failed database and QAQC audits, Measured mineral resources were downgraded to the Indicated category to better 
reflect certainty in the grade estimates.  A reconciliation study comparing the previous two years of mine production data 
against  the  block  model  was  completed  to  support  the  Indicated  classification.    LGGC  concluded  the  designation  of 
Indicated  resources  to  be  appropriate  for  the  March  2014  estimate.    Taking  into  account  the  updated  geological 
interpretation for these zones, LGGC reclassified approximately 430 kt from Indicated resources to Inferred resources.  This 
material was located in the MNFW zone and in areas of the San Roberto zone where there was insufficient understanding 
of structural geology and grade continuity based on the current drillhole spacing.  Infill drilling is required to bring this 
material back to the Indicated category.  

The San Rafael zone, which was estimated by independent consultant Rob Sim, P.Geo, of Sim Geological Inc., in December 
2009, was not a part of the March 2014 resource update.  Since there has been no additional work in this area, the 2009 
San Rafael model has been retained.  The San Rafael mineralized zone (“Minzone”) domain was interpreted using a 
combination of geology codes, plus the presence of mineralization generally above a 0.4% copper equivalent grade that 
took into account contributions from zinc, lead, silver, and gold.  Although San Raphael is more zinc-rich than the San 
Roberto deposit, a copper-equivalent cut-off was used to retain some consistency of the host geology between the two 
areas.  San Rafael is primarily a zinc deposit that contains minor amounts of lead, silver, and copper.  Samples were 
composited downhole to 1 m lengths.  Sample outliers were treated during grade estimation by using a restricted search 
distance and not by top cutting.  Spatial analysis of grade data was completed using correlograms.  Grades were estimated 
by ordinary kriging into a block model with 10 m Easting × 3 m Northing × 3 m Elevation sized blocks.  Search orientations 
were designed to follow a mineralization trend surface created from between the hangingwall and footwall surfaces.  
Model validation included visual inspection of estimated grades in comparison to sample composites, creation of swath 
plots along easting, northing, and elevation sections to assess grade smoothing, as well as evaluation of the grade-tonnage 
curves with respect to theoretical predicted results (referred to as a global change of support).  The validation checks 
showed the models to be valid with appropriate levels of smoothing.   

Mineral resources for the San Roberto, MNFW, and San Rafael zones as of December 31, 2014 are summarized in Table 3 
above a US$35 per tonne net smelter return (“NSR”) cut-off.  The mineral resources estimates in the San Roberto and 
MNFW zones completed by Ali Shahkar, P.Eng. have been depleted to take into account mining activity until December 31, 
2014.  This work was completed by Cozamin Mine staff under the supervision of Jeremy Vincent, P.Geo., Manager of 
Production and Development Geology at Capstone and a Qualified Person under NI 43-101.  No mining activity has been 
undertaken in the San Rafael zone since the completion of the San Rafael zone mineral resources model.

During June 2014, Stantec Consulting LLC (“Stantec”) of Tempe, Arizona, updated the mineral reserves using the March 
2014 mineral resource model (San Roberto and MNFW zones) by LGGC and the 2009 San Rafael mineral resource model 
completed by Rob Sim.  The mineral reserves estimates were based on vein domains codes using a combination of the 
following: minimum vein width; NSR cut-off values of $42.50/tonne for the copper zones and $38.00/tonne for the San 
Rafael zone; and a minimum copper grade of 0.30%. Predefined mining blocks in each of the deposits were reviewed for 
areas  of  contiguous  mineralization  above  these  cut-offs.    Theses  blocks  were  then  included  in  polygons  to  identify 
mineable and recoverable areas.  Longitudinal long-hole stoping, which is the defined stoping method for the zones, does 
not allow for selective mining with the defined stope shape.  Therefore, all blocks of the sub-ore inside the defined stope 
shapes were included in the mineral reserves estimates.  The mineral reserves published in Table 4 are based on the 
reserves estimate completed by Stantec in July.  These have been depleted by Cozamin staff to reflect mining production 
until December 31, 2014 under the supervision of Brad Skeeles, P.Eng., Vice President of North American Operations at 
Capstone, a Qualifed Person under NI 43-101.

Mining Operations 

The Cozamin Mine is an underground mining operation that commenced in 2006.  Ore is extracted using three mining 
methods: cut and fill using waste rock fill, long-hole open stoping, and Avoca - a hybrid of long-hole 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.  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. 

Run of mine ore is stockpiled on surface and sent to the crushing plant.  The crushed ore is stored in two ore bins that feed 
parallel conventional grinding circuits. The resulting product is sent to the copper-lead rougher flotation where a copper-
lead concentrate is produced.  The tailings report to zinc conditioning tanks prior to zinc flotation, where reagents are 
added  to  activate  zinc  mineralization.    The  tailings  go  through  zinc  rougher  and  cleaning  circuits  to  product  a  zinc 
concentrate.    Separate  copper  and  lead  concentrates  are  produced  from  the  copper-lead  concentrate  via  selective 
flotation.  The concentrates are thickened and filtered to produce product suitable for transport. The concentrates are 
trucked to Manzanillo, Colima, Mexico. 

Copper, zinc and lead concentrates are sold by annual tenders to commodity traders.  Cozamin has a processing rate of 
3,300 tonnes per day and life of mine annual production of 18,140 kt copper contained in concentrate. Cozamin has a 
precious metal sales agreement for 100% of its silver production with Silver Wheaton Corp.  The contract expires in April 
2017.  The current mine plans extends the Cozamin Mine operations life to 2020. 

All necessary permits to conduct mining work on the property have been obtained. There are no known factors or risks 
that affect access, title or the ability to conduct mining. Environmental liabilities and issues are limited to those that are 
expected to be associated with an underground base metal operation.  These include an underground mine, associated 
infrastructure, access roads and surface infrastructure including the process plant, waste and tailings disposal facilities 
situation within the area of disturbance. 

The Cozamin Mine’s applicable taxes include the following: 

 

 

 

 

Corporate Taxes - the Mexican corporate income tax is at a 30% rate applied on net income 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 tax.  The mining tax, effective January 1, 2014, is 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.  The Tax Reform also introduced a 0.5% 
mining tax on precious metals that is applied on gross taxable revenues. 
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.

Exploration and Development 

The 2015 exploration program includes a proposed 18,900 meters of underground infill drilling to add certainty to the 
block model with the goal to potentially recover some mineral reserves losses identified in the August 2014 NI 43-101 
Technical Report, as well as step-out exploration drilling on both the Mala Noche Vein and Mala Noche Footwall mineral 
resource areas.  The continuation of surface drilling, which began in 2014 targeting veins in splays off of the Mala Noche 
system not previously been tested, will continue in 2015 with 12,000 meters of surface drilling budgeted. 

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.Geo.; 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 by 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. 

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.   

Project Description and Location 

The Minto Mine is a 3,850 tonnes per day operating copper mine located in central Yukon, located approximately 240 km 
northwest  of  Whitehorse,  Yukon’s  capital.    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).    There  are  no  back-in  rights,  payments  or  other  agreements  or 
encumbrances to which the property is subject other than a Cooperation Agreement with the SFN and a NSR payable to 
the SFN. 

The project consists of 164 quartz claims covering an area of approximately 2,760 ha that are 100% owned by Minto 
Explorations Ltd. (“MintoEx”), a 100% owned subsidiary of Capstone.  The claims have 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. 

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 August 2014) 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 C$42.0M 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-
annual basis. 

MintoEx has obtained a variety of permits in order to conduct ongoing work on site and 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  awaiting 
additional permits to access the new deposits and waste management facilities. Figure 3 illustrates the location of Minto 
infrastructure in relation to the open pit and underground mineral resources and reserves. 

Surface mining at Minto was suspended at the end of the third quarter of 2014 due to delays in receipt of the WUL 
Amendment,  which  is  required  to  permit  pre-stripping  at  Minto  North.    Fresh  ore  from  underground  mining  was 
supplemented  with  stockpiled  ore  to  feed  the  mill  in  the  fourth  quarter  of  2014.  There  were  five  interveners  that 
commented on our WUL amendment application, and the Yukon Water Board presented us with a fourth information 

 32 

 
request on February 6, 2015, which we responded to on February 16, 2015. A public hearing on our application was held 
from March 2 to 10, 2015.  As a result, we do not expect that the Minto North deposit will be stripped as planned at the 
beginning of the second quarter of 2015.  We will continue to work with the Yukon Water Board to secure the required 
WUL amendment as expeditiously as possible, but will not be making any commitment of capital until an acceptable permit 
is received.  Copper prices are currently at levels where the economics of the Minto Mine, without the Minto North 
deposit, are questionable.  We are evaluating all options for optimizing the cash flows from Minto in the current climate.   

FIGURE 3: MINTO INFRASTRUCTURE AND LOCATION OF MINERAL RESOURCES AND MINERAL RESERVES 

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.  During the river freeze and thaw periods, personnel are transported from Whitehorse via charter 
air services that land on the 1,300 m-long airstrip located at the mine. 

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 

 33 

 
 
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 medical 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 28,000.  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  Consolidated Silver Standard (formerly  Silver Standard Mines Ltd.) and Asarco Inc. 
conducted a regional stream sediment geochemical survey in the area.  In 1971, the 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.    Induced  polarization  (“IP”)  and  very-long-frequency-
electromagnetic (“VLF-EM”) geophysical surveys, soil sampling and mapping on the DEF claims followed.  In June 1973, a 
main mineralized body was discovered.  There are no detailed descriptions of historical sampling methods, preparation, or 
analysis by Asarco, and there is no useable core from this period.  In 1974, a winter road was built from Yukon Crossing and 
58  diamond  drillholes  (11,228  m)  on  the  Minto  claims  were  drilled.    From  1975-1976  joint  Feasibility  studies  were 
conducted.   

In 1984, Consolidated Silver Standard 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.  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 was 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 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 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 licence was received. 

From 1973 to 2001, most of the drill core samples were split using a mechanical wheel core splitter (in contrast to a 
diamond saw).  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.    Quality  control 

 34 

 
procedures used during the 1973 to 2001 drill programs are not known, with the exception of 10 samples submitted for 
umpire analysis in 1994.   

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 acquired the Minto 
property.  In 2006, mill construction commenced.  A C$85M 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, the first copper-gold concentrates at Minto Mine were produced and a resource estimate for the Area 2 
deposit was completed.  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 acquired all outstanding shares of Sherwood. 

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 Early Jurassic Age 
Minto pluton and is predominantly of granodiorite composition.  Other rock types, albeit volumetrically insignificant, 
include thin dykes (typically less than 1 m in thickness) of simple quartz-feldspar pegmatite, aplite, and an aphanitic-
textured intermediate composition 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; Minto East 2; Minto South (MSD-a 
consolidation of Area 2, Copper Keel, Area 118 and Wildfire deposits that are now considered one continuous deposit); and 
Ridgetop.  In 2014, we renamed the Fireweed zone to Minto East 2 to reflect the continuity of mineralization between this 
zone and the Minto East zone.  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, with a similar geometry exposed in the exhausted 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 (PEC). 

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 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 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. 

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 
brownfield exploration.  Exploration on the northern half is more sporadic. 

 35 

 
The exploration approach by MintoEx has been 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.  The predominant 
electrical geophysical methods used are Gradient Array Induced Potential (“GAIP”), Dipole-Dipole Induced Potential, and 
Titan-24 DC Induced Potential.  Drill targeting has been 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”). 

GAIP  surveys  were  conducted  in  2006  and  2007  with  a  combined  total  of  171  line  kilometers.    Both  surveys  were 
conducted by Aurora Geosciences of Whitehorse, Yukon.   The GAIP method proved a successful exploration tool for 
locating near-surface mineralization when combined with magnetics; the most notable discovery attributed to this being 
Minto North. 

A modified pole-dipole geophysical survey was conducted in 2009 over areas west and north of the DEF fault.  The survey 
targeted areas of known historical geophysical anomalies, as well as overlapping GAIP coverage were permafrost or deep 
overburden  ground  conditions  returned  poor  results.    A  total  of  20.6  line  kilometers  were  completed  by  Aurora 
Geosciences.  The results of the survey indicated two separate anomalies, one approximately 1,000m due west of Minto 
North, and the second approximately 2,400m due north of Minto North.  Drill  testing results for each anomaly were 
enigmatic in that no significant copper-gold mineralization was encountered despite the intersection of multiple, thick 
sequences of foliated favorable host rock.   

Three separate mise-a-la-masse drillhole IP surveys were completed in 2009, 2010, and 2011, with all three surveys being 
completed by Aurora Geosciences.  The results of the surveys were useful in vectoring step-out drilling at Copper Keel NE 
and at Inferno. 

Another new exploration tool implemented in 2009 included the completion of the deep penetrating Titan-24 geophysical 
survey  of  the  Minto  PEC  from  July  29  to  August  8,  2009.    The  survey  included  three  double  spread  direct  current 
resistivity/induced polarization (“DC/IP”) and magnetotelluric (“MT”) lines totaling 21 line kilometers.  An expanded Titan-
24 DC/IP survey covering about 85% of the property was completed from May 19 to July 15, 2010. Titan-24 surveying for 
both 2009 and 2010 programs were conducted by Quantec Geoscience of Toronto, Ontario. 

The 2009 Titan-24 survey showed a coincidence of significant copper sulphide mineralization of known deposits with 
chargeability anomalies as well as several previously unknown deep anomalies.  The most attractive deep targets were 
located south of Ridgetop, flanking the Minto Main Pit (west, southeast, northwest, and northeast), and flanking the Minto 
North deposit (east, west, and north).  The survey also identified a near surface target southwest of Ridgetop.  MT results 
indicated steeply dipping fault-like structures with an estimated 70⁰ dip to the north, the most prominent being the DEF 
fault.  Preliminary drill testing of the Titan-24 targets spanned from September 4 to October 17, 2009.  Results of the 
drilling were variable returning promising copper mineralization intersections in 9 drill holes at Ridgetop Southwest and 
significant copper-gold mineralization in 2 holes southeast of Minto Pit (Minto East Discovery); however, in 9 holes at 8 
other separate targets no significant copper-gold mineralization was encountered. 

Similar  to  the  2009  Titan-24  survey,  the  expanded  2010  survey  identified  previously  unknown  moderate  to  deep 
anomalies; the most attractive new targets were located east of the Copper Keel trend (Wildfire), at Copper Keel NE, 
southwest of Ridgetop, at Airstrip SW, and northeast of the Minto airstrip.  Drill testing of the 2010 Titan-24 chargeability 
targets spanned from June 25 to November 5, 2010.  Further testing of select Titan-24 targets continued throughout the 
2011 drilling campaign.  Results of the 2010 drilling were variable returning significant copper mineralization in more than 
70  drillholes  east  of  the  Copper  Keel  trend  (Wildfire  discovery),  and  in  4  holes  northeast  of  the  Minto  Pit  (Inferno 
discovery).  Promising copper-gold mineralization was observed in 3 holes southwest of Area 118, 4 holes at Copper Keel 
NE, and in 1 hole at Ridgetop NE.  No significant results were encountered in 5 holes at three other separate targets. 
Results of the 2011 drilling were variable returning significant copper mineralization in more than 70 drillholes at Copper 
Keel NE and 26 holes at the Minto East 2 Discovery.  Similar to 2010, some of the 2011 tested targets did not encounter 
significant copper-gold mineralization despite the intersection of multiple, thick sequences of foliated favorable host rock. 

Future exploration programs will be more reliant solely on electrical/chargeability methods targeting deeper mineralization 
as the near-surface potential and discrete magnetic bull’s-eyes have largely been targeted.  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.  Magnetic data in areas located north of 

 36 

 
Minto North plus areas West and East respectively of the PEC may still be useful as these regions are still relatively under 
explored. 

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 

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 crosscut the sulphide mineralization.  
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 an order of magnitude greater than background. 

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. 

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  potassium-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  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. 

The Minto North, Minto East, and Minto East 2 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.    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 and at 
Inferno North 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.  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.  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. 

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.   

 37 

 
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 

Drilling 

There are currently more than 1,330 drillholes within a roughly 16 square kilometre area at Minto.  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, Minto East 2, and other targets between January and May 2012 using the contractor, Driftwood Diamond 
Drilling Ltd., of Smithers, BC.  MintoEx drilled a total of 106,456 m in 376 vertical and 19 angled, NQ and NTW-diameter, 
diamond drillholes at the Minto South Deposit from February 2006 to July 2011.  The average drillhole length is 270 m.  
Drillhole spacing ranges between 30 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 at the Wildfire and Copper Keel sub-domains.  At Ridgetop, MintoEx drilled a total of 16,850 m 
in 139 NQ-diameter, vertical drillholes and three angled diamond drillholes from May 2007 to September 2009.  The 
average length of the Ridgetop drillholes is 122.5 m.  Drillhole collars are spaced between 20 m and 60 m apart.  The 
mineralized zones dip moderately to the northeast.  At Minto North, MintoEx drilled a total of 11,548 m in 71 vertical and 
17 angled, NQ and NTW-diameter, diamond drillholes from January to October 2009.  The average drillhole length is 
130 m.    Drillhole  collars  are  spaced  between  15 m  and  20 m  apart.  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, NQ-diameter,  diamond 
drillholes from April 2007 to August 2010.  The average drillhole length is 336 m, which are spaced approximately 40 m 
apart.  Mineralized zones are shallowly dipping to the northwest.  At Minto East 2, MintoEx drilled a total of 24,295 m in 13 
vertical and  46 angled, NQ-diameter, diamond drillholes  from 2011 to 2012.  The average drillhole length  is  412 m.  
Drillhole collars are spaced between 40 m and 80 m apart.  At Inferno North, MintoEx drilled a total of 1,566 m in 9 vertical, 
NQ-diameter, diamond drillholes from March to April, 2012.  The average drillhole length is 174 m.  Drillhole collars are 
spaced from 80 to 40 m and 80 to 40 m apart.  The mineralized zone is sub-horizontal. 

A review of drill hole spacing was conducted for various mineralization zones in 2014 and it was identified that in-fill 
drilling was appropriate to reduce the drill spacing in some areas.  The first area targeted was the planned pushback of the 
Area 2 pit (Area 2 Stage 3), with drilling conducted by Driftwood Diamond Drilling Ltd. in the fall of 2014.  Nineteen holes 
were drilled, for a total of 3,026 meters, with the goal of closing the drill spacing to an approximate 40 m grid pattern.  
Additional drilling is planned for 2015. 

Drillhole collar locations were initially located using a differential GPS unit, followed by survey using a Trimble G8 GPS unit 
after completion of the drillhole.  Since 2008, downhole survey measurements were taken primarily using a Reflex™ Flexit 
downhole  survey  tool.    Although  local  magnetite  concentrations  sometimes  prevented  measurement  of  azimuth 
deviations, the tool provided overall readings that were realistic showing minor deviation in azimuth and dip.  In 2010 a 
Relfex™ Maxibor II, which is not magnetically susceptible, was used in 22 drillholes in areas known to be highly magnetic.  
Between 2008 and 2011 we collected magnetic susceptibility data, but we determined that high magnetic susceptibility 
does not imply the presence of mineralization, even though magnetic susceptibility is elevated in mineralized intervals.   

Mineralized intervals measured in the vertical drillholes are considered to be nearly true width because of the shallow-
dipping  nature  of  the  mineralization.    Drillcore  is  transported  from  the  drill  rig  to  the  logging  facility  by  the  drilling 
contractor, where MintoEx personnel log it for geological, sampling, and geotechnical purposes.  Geological data including 
lithology, structure, alteration, and mineralization is recorded for all drillholes.  All drillcore is photographed.   

Sampling and Analysis  

Drillcore samples normally 1.5 m in length in foliated granodiorite (mineralized) and 3.0 m in length in the unfoliated 
granodiorite  (waste)  rock.    The  geological  contact  between  these  units  is  generally  sharp  and  it  is  respected  during 
sampling.  Shoulder samples are taken in the waste at both the upper and lower contacts, consisting of a 1.5 m and a 1.0 m 
sample.  Unfoliated granodiorite units between mineralized units are completely sampled if they are 10 m in thickness or 
less between mineralized, foliated units, otherwise they are sampled at the geologist’s discretion.   

 38 

 
Our quality assurance protocols require standard reference materials (“SRM”), sample blanks, and duplicate samples to be 
regularly  inserted  into  the  sample  stream.    Our  samples  have  generally  been  sent  to  the  ALS  Geochemistry  (“ALS”) 
laboratory in Vancouver, but we have also used SGS Canada Inc. (“SGS”) for parts of our drilling programs.  MintoEx 
inserted one each of an SRM, blank, coarse reject duplicate and pulp reject duplicate with every 16 core samples.  Umpire 
assaying of pulps at a secondary laboratory was conducted periodically, typically involving analysis of 0.5% or more of the 
core samples.  Other quality control measures include random checks of drillhole collar locations using handheld GPS units 
and comparing entries in our database to original data sources.  We consider our samples to be representative and we are 
not aware of any factors that may have resulted in sample biases.  We do not know of any drilling, sampling, or recovery 
factors that could materially impact the accuracy or reliability of the drilling results. 

Bulk density measurements are taken in both mineralized and waste material.  Since 2005, a weight-in-air-weight-in-water 
method has used for bulk density determinations.  Measurements are taken at approximately every 1-3 m in mineralized 
zones, every 5 m in poorly mineralized zones, and every 20-30 m in waste zones.  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. 

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 reference material standards and blank 
material monitors the reliability of assaying results and is also important to prevent sample mix-up and monitor potential 
for  cross  contamination.    Assaying  protocols  typically  involve  regular  duplicate  and  replicate  assays  to  monitor  the 
reliability of assaying results throughout the sampling and assaying process.  

Several audits of our drillhole database have been conducted by SRK and Garth Kirkham between 2005 and 2012, which 
did not discover any significant errors. 

Mineral Resource and Mineral Reserve Estimates 

The mineral resource estimates for the Minto South Deposit (“MSD”) and Ridgetop deposits were completed by Dr. Wayne 
Barnett, Ph.D., Pr.Sci.Nat., of SRK Consulting (Canada) Inc. (“SRK”), an independent Qualified Person as defined by NI 43-
101.  The effective date of the MSD resource estimate is September 13, 2011 and the effective date of the Ridgetop 
resource estimate is August 30, 2010.  Marek Nowak, P.Eng., also of SRK, analyzed the data, reviewed and validated the 
mineral resource estimates for Minto South and Ridgetop.  The MSD comprises the Area 2 (including the Copper Keel 
extension), Area 118, and Wildfire zones that form a part of the same system of mineralization.  The geological model was 
created in Geovia GEMS™ software from cross-sectional interpretations identifying the foliated and non-foliated units, 
weathering horizons, and key fault structures offsetting the mineralization.  Data were composited to 1.5 m lengths.  
Exploratory data analysis indicated gold and copper were highly correlated, so estimation parameters for both of these 
elements were the same.  Top cutting of outlier grades was not undertaken, but their influence was mitigated during the 
estimation process using  restricted  search  ellipses.   Copper and gold were estimated by ordinary kriging  into blocks 
measuring 10 m Easting by 10 m Northing by 3 m Elevation.  Silver and bulk density were estimated using an inverse-
distance-squared  method.    Sample  search  ellipses  were  oriented  to  match  the  directions  of  the  modelled  geology.  
Estimation validation included visual checks, comparison of average grades to assess global bias, and generation of swath 
plots to assess smoothing of blocks compared to the declustered, input, composite data.  For the Ridgetop deposit, the 
same process outlined above was followed to model the geology and conduct the mineral resources estimate.   

The Minto North, Minto East, Minto East 2, 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 Mint East 2 and Inferno North resource estimates is October 25, 2012.

The Minto North geology was modelled using a cross-sectional interpretations taking into account lithology, copper grades 
and site knowledge.  Samples were composited to 1.5 m lengths.  Similar to the MSD and Ridgetop deposits, outlier 
samples were not top cut, but their influence was lessened by the use of restricted search distances above specified grade 
thresholds.  Grades were estimated into blocks measuring 10 m Easting x 10 m Northing x 3 m Elevation using ordinary 
kriging, while bulk density was estimated using inverse distance squared.  Search ellipses were oriented to match the 
directions of the modelled geology.  Estimation validation included visual checks, comparison of average grades to assess 
global bias, and generation of swath plots to assess smoothing of blocks compared to the declustered, input, composite 
data. 

The Minto East deposit is an underground target, located approximately 280 m below the surface.   

Several mineralized layers do exist above the main Minto East 700 zone, but these do not carry sufficient grades to warrant 
evaluation.  The 700 zone was modelled using a cross-sectional interpretation approach.  Samples were composited to 
1.5 m lengths.  Outlier samples greater than 5.2% copper were top cut, otherwise restricted search distances were used to 
limit the influence of outlier grades for gold and silver.  Grades and bulk density were estimated into blocks measuring 
10 m Easting x 10 m Northing x 3 m Elevation using inverse-distance-squared estimation with a three-pass search strategy.  
The  search  ellipses  were  oriented  to  match  the  modelled  geology.    Estimation  validation  included  visual  checks, 
comparison of average grades to assess global bias, and generation of swath plots to assess smoothing of blocks compared 
to the declustered, input, composite data.  Modelling of the Minto East 2, an extension of the mineralization to the east of 
the Minto East underground target, was undertaken using the same process methodology outlined for Minto East.  The 
resources modelling of the Inferno North deposit, located east of Minto North, followed the same process as described for 
the Minto East and Minto North deposits.   

During  2014,  we  removed  mineral  resources  remaining  from  the  Minto  Main  open  pit  from  our  mineral  resources 
statement because we deemed them to no longer be potentially economically viable.  This represented Measured and 
Indicated resources totalling 637 kt at 0.94% Cu, 4 g/t Ag, and 0.1 g/t Au and Inferred resources totalling 2 kt at 0.53% Cu, 
4 g/t Ag, and 0.2 g/t Au, all reported above a 0.5% Cu cut-off grade.  This material was located peripheral to the margins of 
the open pit. 

Mineral resources reported in Table 5 are based on the resources models completed by Dr. Wayne Barnett, Pr.Sci.Nat. and

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  estimates  for  Minto  North  Open  Pit,  MSD  –  118  Pit,  MSD  –  Area  2  Pit  and  Ridgetop  Pits  were 
completed by Pooya Mohseni, P.Eng.  The mineral reserve estimates were generated using a NSR model that estimates 
metal prices, exchange rates, mining dilution, mill recovery, concentrate grade, and offsite costs.  Economic pit shells were 

 41 

 
generating using the Whittle™ mine planning software.  The pit shells were further optimized by Minto personnel to 
developed detailed pit designs.  In the fourth quarter of 2013, an engineering change occurred whereby the Ridgetop 
mineral reserves were removed due to potentially lower metallurgical recoveries caused by higher than anticipated copper 
oxide in the ore.  In 2013 and 2014, open pit mining was executed in the Area 2 and 118 open pit and we anticipate mining 
to commence in the Minto North open pit in 2015.  We have exhausted mineral reserves from the Area 118 open pit. 

The mineral reserves for the MSD -118 / Area 2 Underground, Minto East Underground, MSD – Copper Keel Underground, 
and MSD – Wildfire Underground were completed Pooya Mohseni, P.Eng.  The mineral reserves estimates were generated 
using a NSR model and then reported above a NSR cut-off value of C$ 64.40/t.  Pre-defined mining blocks in each deposit 
were reviewed.  These blocks were then included in polygons that identified mineable and recoverable areas.  Post-pillar 
cut-and-fill mining allows for limited selective mining within the defined levels.  In 2014, Area 2/118 underground mineral 
reserves  were  depleted  with  the  mining  of  the  M-zone  (completely  mined),  and  through  limited  development  and 
production in the Area 118 underground.  The success in M-zone mining established the viability of the long-hole mining 
method at Minto, proving its applicability to zones ranging from 8 m to 25 m in thickness. Therefore, the mineral reserves 
for the Area 118 underground zone were updated based on the new design using long-hole mining.  The change to the 
mineral reserves is not material in nature.  All other mineral reserves remain unchanged except for the stockpiles, which 
experienced  significant  depletion.    Mineral  reserves  presented  in  Table  6  take  into  account  mining  activities  until 
December 31, 2014.

Mining Operations 

The Minto Mine is an open pit and underground mining operation that commenced in  2007.  Open pit mining uses 
conventional drill and blast, and truck and shovel contractor fleet.  Pit design vary on the site but are typically  12 m 
benches with a double bench configuration.  Underground operations use room and pillar, post-pillar cut and fill, and long-
hole open stoping mining methods.  Each method has been assigned to individual mining blocks depending on the physical 
characteristics of the geology and its suitability to one of the above methods.  Access to the underground workings is via a 
single service and haulage ramp. 

Run of mine ore is stockpiled on surface depending on the copper grade of the material. A loader transports the stockpiled 
material to the primary crusher which feeds a gyratory crusher. The crushed product fed to a conventional grinding and 
flotations circuit to produce a bulk copper concentrate. The concentrate are thickened and filtered to produce product 
suitable for transport.  The product is transported by truck to Skagway, Alaska for export. 

The copper concentrate is sold by annual tenders to commodity traders. 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 $312/oz Au and $4.06/oz Ag. Minto  has a 
processing rate of 3,850 tonnes per day and average life of mine annual production of 18,140 kt copper contained in 
concentrate containing silver and gold by-products.  The current mine plans extends the Minto Mine operations life to 
2020.  In 2014, open pit mining activities were primarily focused on mineral extraction of the Area 2 Stage 2 Pit and 118 pit.  
Surface deposits will continue to be developed as open pit that will rely on a contractor mining approach. Underground 
mining  activities  were  focused  on  the  M-zone  (component  of  Area  2  underground  UG  reserves)  development  and 
production. In the fourth quarter of 2014 underground activities in 118 restarted applying long-hole mining method.  

The Yukon Environmental and Socio-economic Assessment Board completed its evaluation for the Phase V/VI expansion in 
April  2014.  An  amended  and  renewed  Quartz  Mining  Licence  for  the  entire  Phase  V/VI  expansion  was  received  in 
December 2014.  Minto is awaiting its Water Use Licence amendment for Phase V/VI operations as discussed in more detail 
above.   

Federal and Territorial income tax applies to the Minto Mine.  Taxable income generally starts with the before-tax cash 
flow 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. 

 43 

 
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 2015, although a limited amount of in-fill drilling, to tighten up spacing for 
areas of existing reserves, will be conducted. 

The current mine plan calls for the first Minto North ore to be milled starting in September 2015, with high grade ore to be 
mined from February 2016 until the end of the second quarter of 2016, at which time the Minto North pit will be fully 
depleted. Minto South underground ore production is budgeted to continue until November 2015, pausing while the mill 
processes Minto North ore and access is developed for the next area of underground mining.  

Santo Domingo Project (Chile)  

The Santo Domingo Project is the subject of a report titled “Santo Domingo Project, Region III, Chile, NI 43-101 Technical 
Report on Feasibility Study” dated May 22, 2014 (the “Santo Domingo Report”), that summarizes the Feasibility Study 
completed on the Project in 2014.  This technical report was authored by Joyce Maycock, P.Eng., David Frost, FAusIMM, 
Vikram Khera, P.Eng., Carlos Guszman, FAusIMM, Roy Betinol, P.Eng., Hans Gopfert, P.Eng., Anna Klimek, P.Eng., David 
Rennie, P.Eng., and Tom Kerr, 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 NI 
43-101 Technical 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 7 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 project was owned by Far West, which was formerly a TSX-listed mineral exploration company headquartered in 
Vancouver.  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.  On June 17, 2011, Far West was acquired by Capstone at the same time 
as the Company entered into a strategic relationship with KORES.  The terms of this relationship provided for amongst 
other things, a private placement in the equity of Capstone, 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 copper and iron from the project on prevailing 
market terms. 

Far West, a subsidiary of Capstone, controls 100% of four groups of concessions with a total of 178 claims (82 exploitation 
concessions totalling 19,375 ha and 96 exploration concessions totalling 17,000 ha) that cover a total of 36,375 ha and 
includes the areas of the planned mine site, plan area, and auxiliary facilities including proposed port facilities and the 
planned  seawater  and  concentrate  pipelines  from  the  port  to  the  mine.    The  centre  of  the  deposit  is  located  at 
approximately 26°28'00”S and 70°00'30”W.   

No surface rights are currently held by Capstone in the  project area, but the process to acquire surface rights is well 
understood.  We have proposed to consolidate Capstone’s property in the areas covering the deposit and the process 
facilities by purchasing these lands through the Ministerio de Bienes Nacionales.  It will be necessary to either acquire a 

 44 

 
total of 3,901.3 ha or complete the creation of mining easements for the installation and use of various facilities.  Capstone 
also proposes to apply for one or more mining rights-of-way in the areas of interest of the project such as the pipeline 
route,  access  roads  and  off-site  ancillary  facilities  to  safeguard  these  areas.    The  project  has  received  government 
guarantees for the rights of way required by the Project for the areas currently identified.  There is sufficient suitable land 
available within the exploitation concessions for the planned tailings disposal, mine waste disposal, and mining-related 
infrastructure such as the open pit, process plant, workshops and offices.   

The project as currently envisaged will not require an application for water rights.  The water for the operation will consist 
solely of seawater.  A maritime concession has been requested to allow the extraction of seawater.  

There are 752 identified permits that will be required to support operations.  Fifteen of these permits are considered to be 
on the critical path for timely construction and start-up of the project. 

Accessibility, Climate, Local Resources, Infrastructure and Physiography 

Access to the Santo Domingo property area is 1  km  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 approximately 16,000 people.  Chañaral is a deep-sea 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 
centimetres in height.  Hillsides and peaks are generally devoid of any vegetation.  In spite of the dry conditions, hills 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 m 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.

FIGURE 4: SANTO DOMINGO PROPOSED PROJECT INFRASTRUCTURE  

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 

 46 

 
 
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, who then flew a Falcon™ gravity and magnetic 
survey over a portion of the northern Chilean Iron Belt, including the Santo Domingo Project area.  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. 

Exploration comprised initial geological mapping (50 km2) at 1:25,000 scale, surface and drainage sampling, interpretation 
of existing airborne geophysical data, and induced polarization (“IP”) survey, and core and reverse circulation (“RC”) drilling 
that outlined the Santo Domingo Sur (“SDS”), Estrellita, and Iris deposits.  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.  An initial copper-gold resource estimate was performed in 2006 for the SDS deposit 
and updated in 2007, which then included copper-gold resource estimates for Estrellita and Iris.  As of May 31, 2010, 
drilling in the Santo Domingo area totalled 106,886 m in 398 holes.   

In 2008, a preliminary economic assessment (“PEA”) was undertaken.  This envisaged two open-pit mining options, one 
being mining the SDS deposit for the recovery of copper, gold and iron from magnetite; the second being mining the SDS 
and Iris deposits for the recovery of copper, gold and iron from magnetite and hematite.  The resource estimate supporting 
the PEA was updated to include iron as an element of interest.  Results indicated that the options were revenue negative 
under the assumptions in the study; however, changes to the base-case metal price assumptions did result in positive 
economics, and additional work was recommended.   

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  area  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 specular hematite.  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. 

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 Chañarcillo Groups.  The Bandurrias Group is defined 
as a predominantly volcanic sequence of andesite flows and volcaniclastic rocks. Chañarcillo Group rocks consist largely of 
limestone and calcareous marine sediments. Both definitions match observed geology on the Santo Domingo Project.  The 
project area is divided into a number of structural blocks with different lithological characteristics suggesting the blocks are 
at different levels. 

 47 

 
Exploration 

Much of the exploration work in the Santo Domingo area was conducted by previous owners of the property.  Exploration 
work completed by Capstone between August 2011 and May 2014 consisted of a detailed aerial survey of the plant site 
area using a scale of 1:1,000 and a 1 m contour spacing, which was prepared by Fugru Interra S.A. in 2012.  The topography 
covers an area of approximately 16,000 ha for the plant site, port facilities and pipeline routes.   

Exploration  work  undertaken  on  the  project  in  October  2013  consisted  of  a  versatile  time-domain  electromagnetic 
(“VTEM”) and aeromagnetic geophysical survey covering 356 line-kilometres by Aeroquest Airborne or Aurora, Ontario, 
Canada.  In November 2013,  Aeroquest Airborne conducted an airborne z-axis tipper electromagnetic (“ZTEM”) and 
aeromagnetic  geophysical  survey  covering  369  line-kilometres.    In  2014  Condor  Consulting  Inc.  (“Condor”)  assessed 
available geophysical datasets from both the recent and historical airborne and ground surveys carried out during the past 
12  years  in  the  project  area.    The  work  resulted  in  the  geophysical  characterization  of  the  signatures  of  the  three 
mineralized occurrences (Santo Domingo, Iris, Estrellita) and the generation of seven target zones of varying priority for 
follow-up exploration.  

The project has been explored for its large tonnage potential as a primary consideration.  There has been no exploration 
targeting small lenses of mineralization in the 1-5 Mt range.  Oxide mineralization has also not been targeted specifically.  
Additional potential exists for iron mineralization without copper, which so far has been deemed uneconomic by itself, but 
has potential once an operation is built in the project area.  The main iron potential is located around Iris Norte and to the 
south of Santo Domingo Sur, where magnetite occurs in skarn zones of unknown size. 

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 replacement-style 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 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.  

 48 

 
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 specular hematite structures. 

Drilling 

In late 2011 and early 2012, Capstone conducted an infill drilling campaign that was designed to elevate Indicated mineral 
resources located within the projected first three years of production to the Measured resources category.  A secondary 
purpose was to collect material for metallurgical test work at the feasibility-study level.  The campaign consisted of 66 
diamond drillholes for a total of 13,282 m of additional drilling.  A revised mineral resources estimate incorporating the 
results of the latest infill drilling campaign has been included in the published NI 43-101 Technical Report as well as the 
completed 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.  The diamond drilling was conducted by various types of 
equipment. HQ-diameter core was typically drilled to a depth of approximately 300 m, below which NQ-diameter core 
(47.6 mm diameter) was drilled.  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 diamond drillholes before 2010) or two-metre (diamond drillholes 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.  Drillhole 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.    Downhole  surveying  was  conducted  using  a  combination  of 
gyroscope and accelerometer, with measurements taken every 10 m. 

Sampling and Analysis 

Reverse circulation drill cuttings were collected at 2 m intervals.  Core was nominally sampled at 2 m intervals.  Samples for 
assay were marked at 1 m and 2 m intervals by technicians and subsequently adjusted by the geologist to correspond to 
major lithological contacts.  For programs conducted prior to 2011, sample lengths were not less than 0.5 m and most did 
not exceed 2 m.  The shortest and longest sample lengths in 2011–2012 were 0.7 m and 2.7 m, respectively, and most 
samples were 2 m long. 

The primary analytical laboratory was ALS Chemex, and the facilities in La Serena, Chile and Antofagasta, Chile were used. 
Both of these facilities have ISO 9001:2008 accreditation and La Serena has ISO 17025 accreditation. Sample preparation 
consisted of drying, crushing to minus #10 Tyler >70%, homogenizing and then pulverizing to minus #200 Tyler >85%. 
Samples were analysed for 27 elements via ALS Chemex procedure ME-ICP61, using inductively coupled plasma (“ICP”).  
Gold assays were determined using fire assay with an AAS finish.  Copper values over 10,000 ppm were re-assayed.  Due to 
the ME-ICP61 method understating the iron content, 7,401 samples from the 2010 drill program were resubmitted for 
assay using a method with a more aggressive digestion; including all samples over 15% Fe inside the existing block model 
for which sample material was still available.  Soluble copper analysis was conducted on 1,035 samples from 2011–2012 
drilling. 

A total of 19,302 magnetic susceptibility measurements have been recorded.  There are 2,229 density measurements, 
performed by Far West Mining personnel on core samples using the water displacement method.  Rosco Postle Associates 
Inc. (“RPA”) developed regression formulae based on the specific gravity values reported by Far West Mining to convert 
volumes to weights, using Fe concentration as the independent variable. 

The  QAQC  protocols  have  remained  largely  consistent  throughout  all  programs  conducted  by  Far  West  Mining  and 
Capstone. Minor changes have been implemented by Capstone to accommodate issues and recommendations from past 
programs and to include magnetic susceptibility measurements. Certified reference materials (“CRM”), or standards, are 

 49 

 
inserted every 25th sample, constituting 4% of the total number of samples submitted.  Blanks, consisting of common 
Portland cement, were inserted every 50th sample.  Field duplicates are taken every 25th sample.   

RPA considers that 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 style.  Sampling methods are 
acceptable, meet industry-standard practice, are appropriate for the mineralization style, and are acceptable for Mineral 
Resource estimation.  The quality of the analytical data is reliable, and analysis and security are performed in accordance 
with exploration best practices and industry standards. 

Security of Samples 

The logging facility is fenced, locked when not occupied, and is secure.  Samples are handled only by employees or their 
designates (i.e. ALS personnel).  Regular data verification programs have been undertaken by third-party consultants from 
2005 to 2014 on the data collected in support of the mineral resources and mineral reserves estimates on the Santo 
Domingo  Project.    RPA  considers  that  as  a  result  of  this  work,  the  data  verification  findings  acceptably  support  the 
geological  interpretations  and  the  database  quality,  and  therefore  support  the  use  of  the  data  in  Mineral  Resource 
estimation. 

Metallurgical Sampling Program 

In 2014, 13 drillholes totalling 1,484 m of reverse circulation and 1,535 m of diamond core drilling (3,019 metres total) to 
obtain fresh material for additional metallurgical sampling were completed.  The first five years of mine production was 
targeted during the drilling program and was completed solely within the Santo Domingo pit limits.  The rock chips from 
the reverse circulation drilling were logged and bagged.  Portions of the rock chips are to be used for the commissioning of 
the metallurgical testing pilot plant.  The core obtained during diamond drilling was taken to the Diego de Almagro core 
storage area with all core being logged and having magnetic susceptibility testing completed prior to cutting.  The core was 
then cut into a single half core and two quarter core sections.  One of the quarter core sections was sent to ALS Minerals in 
Antofagasta for assaying; the second quarter core section is being archived at Diego de Almagro; with the half core section 
to be provided to ALS Minerals in Santiago for the pilot plant testing program.  A total of six composite samples (in addition 
to the commissioning sample) are to be prepared and tested during the pilot plant program. 

Mineral Resource and Mineral Reserve Estimates 

David Rennie, P.Eng., of RPA, is the Qualified Person responsible for the preparation of the mineral resources estimates for 
the Santo Domingo Project.  The mineral resources estimates for Santo Domingo Sur, Iris, and Iris Norte have an effective 
date of August 31, 2012 and the mineral resources estimate for Estrellita has an effective date of October 30, 2007.   

RPA  constructed  3D  wireframe  or  solid  models  and  gridded  surfaces  of  the  mineralized  zones,  fault  structures  and 
topography for use in constraining the block grade interpolations.  The principal controls were lithology and structure; 
however, in some places a nominal grade shell boundary was used.  Most zones required construction of wireframes for 
post-mineral dikes  that transect the  mineralized  mantos.   There are also some  sequences of barren tuffs that were 
modelled.  A wireframe model was also created to enclose oxidized material which has been demonstrated to yield much 
lower metallurgical recoveries than the un-oxidized mineralization.  A modest amount of underground and open pit mining 
has been carried out at Estrellita.  Far West personnel provided raw cavity monitoring device (CMD) data from which RPA 
was able to construct approximate wireframe models of the void spaces.  A grade capping strategy was utilized that 
represented approximately 0.2% of the total number of assays in the Santo Domingo Sur, Iris and Iris Norte deposits.  
Grades at Estrellita were capped at 3% copper and 0.3 g/t gold.  Samples from Santo Domingo Sur, Iris and Iris Norte were 
composited in downhole intervals of 4 m starting at the contact for each zone and continuing until the hole exited the 
zone.  Drill samples at Estrellita were composited to 2 m lengths, weighted by both length and density.  Grades for copper, 
gold, iron, and magnetic susceptibility were interpolated into each block using ordinary kriging for the Santo Domingo Sur, 
Iris and Iris Norte deposits.  The interpolation was configured to use an ellipsoidal search with a minimum of three and a 
maximum of 18 composites and a maximum of three composites allowed from any one drillhole.  For Estrellita, ordinary 
kriging was utilized to interpolate copper and gold grades into each block.  Iron was not estimated.  The search was 
constrained to a minimum of three and maximum of 12 composites, with a maximum of three composites from any one 
drillhole.  Grade interpolations were validated, and no significant errors or biases were noted.  Blocks receiving an estimate 
for copper were assigned to at least the Inferred category at Santo Domingo Sur, Iris and Iris Norte.  All blocks with an 

 50 

 
average distance to composites of 200 m or less and for which the nearest composite was within 100 m were classified as 
Indicated.  Within the area of infill drilling completed in 2011–2012, a boundary was drawn around the 50 m drilling 
pattern and Indicated blocks encompassed by it were nominally assigned to the Measured classification.  The final step in 
the classification was to use the oxide wireframe to tag oxidized blocks and remove these from the Mineral Resources.  The 
classification  of  Indicated  at  Estrellita  was  applied  to  all  blocks  estimated  by  at  least  two  drillholes  with  the  closest 
composite less than 65 m away. Remaining blocks were classified as Inferred. 

RPA ran a pit optimization during 2009 using a Lerchs–Grossmann (LG) algorithm for Santo Domingo Sur, Iris and Iris Norte 
deposits.   Copper equivalent  (CuEq) grades  were calculated using estimates  for recovery, toll treatment/refinement 
charges, and transport costs for each metal and based on the operating cost estimates contained in the 2008 Preliminary 
Assessment.  At the 0.25% CuEq cut-off, all but 5% of the Mineral Resources were captured by the pit shell.  On the basis of 
this result, it was concluded that there was little merit in restricting the Mineral Resources to those blocks contained only 
within the pit shell.  In RPA’s opinion, the shape and depth of the Mineral Resources have not changed since the previous 
estimate and it is still valid to consider them as having reasonable prospects of economic extraction by open pit mining.  
The Estrellita resource estimate is not constrained within a LG shell.  RPA’s opinion was that a 0.3% Cu cut-off would be 
appropriate for the reporting of the estimate.  At the time of the estimate in 2007, RPA considered that the 0.3% Cu cut-off 
was similar to that used in other operations of similar size and grade.  Table 7 summarizes the Santo Domingo mineral 
resources as at December 31, 2014.  No mining has occurred on the property. 

Risk factors that could potentially affect the Mineral Resources estimates include the following: long-term commodity price 
and exchange rate assumptions; changes in the assumptions used in the LG shell constraining mineral resources at Santo 
Domingo Sur, Iris, and Iris Norte; the assumed mining methods and cost assumptions for the Santo Domingo Sur, Iris, and 
Iris Norte deposits being those from the 2008 Preliminary Economic Analysis are not those arising from the Feasibility 
Study;  no  LG  shell  being  employed  to  support  reasonable  prospects  at  Estrellita;  delays  or  other  issues  in  reaching 
agreements with local communities, changes in permitting, surface rights and environmental assumptions.

resources for the Estrellita deposit have an effective date of October 30, 2007. 

5.  Mineral Resources for the Santo Domingo Sur, Iris, and Iris Norte deposits are reported using a cut-off grade of 0.25% copper 

equivalent (CuEq).  CuEq grades are calculated using average long term prices of US$3.50/lb Cu, US$ 1,500/oz Au and US$ 
1.94/dmtu Fe (US$ 120/dmt conc. At 62% Fe). The CuEq equation is: Metal Value = Grade*Cm*R%/100*(Price-TCRC-
Freight)*(100-Royalty)/100, where Cm is a constant to convert grade of metal, m, to metal price units; R is metallurgical 
recovery and %Cu Equivalent = (Cu Value + Au Value + Fe Value)/(Cu Value per 1%Cu). 

6.  An assessment of Mineral Resources for the Santo Domingo Sur, Iris, and Iris Norte deposits was performed using a Lerchs–

Grossman pit shell that has the following assumptions: pit slopes averaging 45°; mining cost of US$1.19/t, processing cost of 
US$ 4.49/t; processing recovery of 85%; selling price of US$2.25/lb, and a selling cost of US$0.247/lb. At the 0.25% CuEq cut-
off, all but 5% of the Mineral Resources were captured by the pit shell. On the basis of this result, it was concluded that there 
was little merit in restricting the Mineral Resources to those blocks contained only within the pit shell. Accordingly, the 
Mineral Resource inventory was reported in its entirety. 

7.  Mineral Resources for the Estrellita deposit are reported using a cut-off grade of 0.3% Cu. 
8. 

Rounding as required by reporting guidelines may result in apparent summation differences between tonnes, grade and 
contained metal content. 

Mr. Carlos Guzman, CMC, an NCL Ingeniería y Construcción SpA. (“NCL”) employee, is the Qualified Person responsible for 
the preparation of the Santo Domingo mineral reserves estimate as a part of the 2014 Feasibility Study.  The effective date 
of the mineral reserves estimate is May 2, 2014.   

Pit optimization, mine design and mine planning were carried out by NCL using the 2012 block model prepared by RPA and 
did not include consideration of material classified as Inferred.  Inferred Mineral Resources were treated as waste.  A block 
size of 12.5 m Easting x 12.5 m Northing x 12 m Elevation was selected for the block model.  The selected block size was 
based on the geometry of the domain interpretation and the data configuration.  The mining cost estimate for the pit 
optimization process is based on studies developed by NCL during 2012.  The estimated average project mining cost was 
separated into various components such as fuel, explosives, tires, parts, salaries and wages, benchmarked against similar 
current operations in Chile.  Each component was updated for first-quarter 2013 prices and the exchange rate from Chilean 
Pesos to US dollars.  This resulted in an estimated mining cost of approximately $1.53/t.  The metal prices, processing 
costs,  refining  costs,  and  processing  recoveries  were  provided  to  NCL  by  Capstone.    A  number  of  calculations  were 
performed in the model in order to determine the NSR of each individual block.  The internal (or mill) cut-off of $7.84/t 
milled incorporates all operating costs except mining.  This internal cut-off is applied to material contained within an 
economic pit shell, where the decision to mine a given block was determined by the pit optimization and was applied to all 
of the Mineral Reserve estimates.  Marginal ore was calculated for the same $7.84/t cut-off, but for a NSR determined at 
higher metal prices.  Final slope angles used for the pit optimization process were a result of multiple iterations and 
analysis carried out by the NCL mining team and geotechnical specialists Derk Ingeniería y Geología Ltda (“Derk”).  The 
original block model was based on an ore percentage with dimensions of 12.5 m x 12.5 m x 12 m, resulting in a 1,875 m3 
block volume; this means that every block has a defined “ore” proportion with an ore density, and a corresponding 
“waste” proportion with a waste density.  To accommodate selective mining methods, any resource block with an ore 
percentage that was <10% was treated as waste.  Blocks with an ore percentage that was higher than 90% were diluted 
with waste such that all high-ore blocks were considered to contain only 90% ore.  Selective mining therefore will be 
performed on those blocks that have an ore percentage of between 10% and 90%.  The Santo Domingo mineral reserves 
estimate is summarized in Table 8. 

In the opinion of the NCL, the main factors that may affect the Mineral Reserves estimate are metallurgical recoveries and 
operating costs (fuel, energy and labour).  NCL notes that the base price, as well as changes in the price of metals, even 
though this is the most important factor for revenue calculation, does not affect the Mineral Reserves estimate to any 
significant degree.  A revenue factor of 0.86 was used for the LG shell that was employed as the guide for the practical 
design for both the Santo Domingo and Iris Norte pits.  This selected revenue factor is conservative and as such allows for a

*Notes: 
1. 

The mineral reserves estimate have an effective date of May 2, 2014 and were prepared by Mr. Carlos Guzman, CMC, and 
employee of NCL.   

2.  Mineral Reserves are reported as constrained within Measured and Indicated pit designs, and supported by a mine plan 

featuring variable throughput rates and cut-off optimization.  The pit designs and mine plan were optimized using the following 
economic and technical parameters: metal prices of US$ 2.75/lb Cu, US$ 1,275/oz Au and US$80/dmt of Fe concentrate; 
recovery to concentrate assumptions of a maximum of 93.6% for Cu and 75% for Au, with magnetite concentrate recovery 
varying on a block-by-block basis; copper concentrate treatment charges of US$70/dmt, U$0.07/lb of Cu refining charges, 
US$5.0/oz of Au refining charges, US$48/wmt and US$3/wmt for shipping Cu and Fe concentrates respectively; waste mining 
cost of $1.53/t, mining cost of US$1.53/t ore, and process and G+A costs of US$7.84/t processed; average pit slope angles that 
range from 37.6º to 43.6º; a 2% royalty rate assumption, and an assumption of 100% mining recovery.   
Rounding as required by reporting guidelines may result in apparent summation differences between tonnes, grade and 
contained metal content. 

3. 

Mining Operations 

A mine plan was developed for the Santo Domingo Project to process 60,000 tpd to 65,000 tpd of feed (21.9 to 23.7 Mt/a) 
with a peak total mining rate of 107.5 Mt/a in Years 1 to 4.  Because of the softer characteristics of the initial feed (higher 
copper content and lower magnetite), an initial period of five years was scheduled for a plant feed of 65 kt/d.  From Year 6 
the plant throughput is scheduled for 60 kt/d.  Year 1 feed to the plant is made up of material mined during pre-production 
and Year 1.  Oxide material has been identified and will be stockpiled separately.   

Mill throughput was also restricted to a magnetite concentrate production capacity of a maximum 4.5 Mt/a up to Year 10; 
and 5.4 Mt/a from Year 11.  For the first 5 years of operation, Santo Domingo will have an annual average production of 
approximately 248 million pounds of copper contained in 388,000 dmt of concentrate (at an average copper content of 
29%).  The life of mine (“LOM”) average is 128 million pounds of copper in approximately 200,000 t of concentrate per year 
over a period of approximately 18 years.  The total life of mine production is estimated to be 2.29 billion pounds of copper 
contained in 3.58 million tonnes of concentrate.  For the same period, the average magnetite concentrate production is 
estimated to average 3.26 million dmt per year.  The magnetite concentrate production will average 4.19 million dmt per 
year  over  the  life  of  mine  with  a  total  estimated  production  of  approximately  75.08  million  dmt.    The  first  5  years 
production does not include the Year 0 ramp up. 

The final pit design was based on a Lerchs–Grossmann (LG) shell that used a copper price of $2.75 per pound and US$ 80/t 
for magnetite concentrate.  Two pits, the Santo Domingo pit and the Iris Norte pit, were designed.  The Santo Domingo pit 
will have four phases; three mining phases are planned for the Iris Norte pit.   

In the Santo Domingo pit, the Phase 1 targets the material with the highest grade and lowest strip ratio in the central area, 
down to 892 m elevation.  Phases 2 and 3 are successive expansions to the north, down to 772 m and 736 m elevation, 
respectively.  Phase 4 in Santo Domingo is in the area called Iris which is at the north of the Santo Domingo pit, but has a 
separate access to the east side and will go down to 676 m elevation. 

 53 

 
 
Three mining phases were designed in Iris Norte, as successive expansions from south to north, going down to 736 m, 
724 m and 664 m elevation, respectively.  Each phase has access from the east and west sides. 

The Santo Domingo pit will have two exits on the west side providing access to the ROM pad area and the primary crusher.  
On the east side there will be another exit to access the main waste storage area.  The final pit will be 2,200 m long in the 
north–south direction and 1,500 m wide in the east–west direction.  The pit bottom will be at the 676 m elevation and the 
highest wall will be about 552 m on the southeastern side.  The total area to be disturbed by the pit is approximately 
229 ha. 

The Iris Norte pit will have one exit on the west side providing access to the run-of-mine (ROM) pad area and the primary 
crusher.  On the east side there will be an exit to access the waste storage area.  The final pit will be 1,600 m long in the 
north–south direction and 900 m wide in the east–west direction.  The pit bottom will be at the 664 m elevation, and the 
highest wall will be about 315 m on the north side.  The total area to be disturbed by the pit is about 124 ha. 

Mine equipment requirements were calculated based on the annual mine production schedule, the mine work schedule 
and equipment hourly production estimates.  The study is based on operating the mine with 42 m3 capacity hydraulic 
excavators (shovels) and trucks with a capacity of 290 t.  The fleet will be complemented with drilling rigs for ore and 
waste.  Auxiliary equipment will include tracked dozers, wheel dozers, motor graders and a water truck.  A small drill rig 
was also included for pre-splitting purposes. 

The primary crushing plant will receive run-of-mine feed directly from the open pits.  The crusher is designed to allow two 
290 t trucks to discharge directly into the crusher dump pocket.  The crushed product will be conveyed to the coarse ore 
stockpile (COS) which has a live capacity of six to eight hours of operation.  From the COS ore is then conveyed to the SAG 
mill.  The SAG mill product will discharge onto a conventional vibrating deck screen with the screen undersize pumped to 
two separate batteries of hydrocyclones.   

The hydrocyclone overflow streams (the copper flotation circuit feed stream) with a P80 of 180 µm will be fed to a single 
rougher;  single  scavenger;  and  three  stage  cleaner  concentrate  production  plant.    The  rougher  concentrate  will  be 
reground using a vertical mill prior to introduction to the cleaner/scavengers.  The rougher flotation stage tailings will be 
pumped to magnetic separation that consists of two lines each with five individual primary LIMS (1,000 gauss low intensity 
magnetic separators) magnetic drum separators.   

The rougher magnetic concentrate from each magnetic drum line will be sent to grinding and classification; the rougher 
magnetic  concentration  tailings  will  report  to  the  main  plant  tailings  stream.    The  cleaning  circuit  magnetic  LIMS 
concentrator  will  consist  of  two  parallel  lines  each  with  three  LIMS  drum  separators  operating  in  a  counter-current 
configuration to facilitate high selectivity.  The final magnetite concentrate will be pumped to the magnetite concentrate 
thickener prior to being sent (via a 12 inch pipeline) to the magnetite filter plant located at the port.   

The first stage of tailings thickening (pre-thickening) will be conducted at the process plant and the second stage (final 
thickening) is conducted at the TSF area.  Recovered water from the thickeners will be pumped back to the process water 
pond with thickened tailings being transferred to the TSF area for deposition.  

Copper concentrate will be filtered at the process plant.  During the concentrate filtration washing stage, desalinated water 
will replace the seawater contained in the copper concentrate cake to reduce the chloride content to less than 300 ppm.  
Copper concentrate filter cake will discharge by gravity to the copper concentrate stockpile. 

The magnetite concentrate will be received at the port in an agitated storage tank and then pumped directly to the filter 
plant to obtain a magnetite concentrate.  There will be four horizontal filter presses with desalinated water used for 
washing to reduce the chloride content of the concentrate to less than 300 ppm.  The magnetite concentrate filter cake 
product will discharge onto a conveyor  feeding the concentrate transfer tower and then the magnetite concentrate 
stockpile.  

All of the process makeup water will be seawater prior to the rinsing of the copper and magnetite concentrate during the 
filtering process.  Rinse water used during the filtering process will be supplies by reverse osmosis water treatment plants 
located at both the port and the process plant. 

 54 

 
Both the copper and magnetite concentrate will be ship loaded at the port for transport to selected buyers.  KORES is 
required  to  purchase  50%  of  the  annual  production  of  copper  and  iron  ore  concentrates  produced  by  the  project.  
Capstone  will  market and  sell the remaining 50%.   The KORES terms and conditions  will reflect the Capstone terms 
negotiated independently in the market.  Capstone is currently researching the market for buyers for the remaining 50% of 
the copper and iron concentrate production. 

Baseline  environmental  studies  were  carried  out  for  communities  in  the  area  of  influence  of  the  project:    Diego  de 
Almagro, Inca de Oro, El Salado, Chañaral, Flamenco, Torres del Inca, Obispito and Caldera.  

Physical  environment  baseline  studies  included  characterization  of  climate,  meteorology,  air  quality,  sedimentable 
particulate material (SPM), gases, noise and vibration, geology, geomorphology, natural hazards, soils, hydrology and 
hydrogeology.  The marine environment baseline studies included characterization of the physical environment, chemical, 
and biological.  The biotic environment baseline studies addressed the fauna and flora components of the project.  The 
anthropological environment baseline studies for the port and proposed mine site included the description of human 
component, constructed environment, cultural heritage and palaeontology and landscape issues.  Baseline studies were 
also completed to address current water resources.  Based upon the study results, no impacts to local water resources are 
anticipated as the project will use seawater for the mining process.   Four key areas of risk were identified from the 
completed baseline studies, as follows: 

  Water: 

o  Alteration of the surface water flow and drainage patterns 
o  Alteration in the underground water flow and/or water quality 

 

Air quality: 
o 

Increases in the levels of breathable particulate material (PM10), breathable fine particulate material 
(PM2.5) and gases (primarily as a result of wind activity on stockpiles, dust generation from construction 
and mining activity and material transport)  
Increases in levels of sedimentable particulate matter 

o 

  Marine environment: 

o  Potential disruption to benthic communities due to the operation of the seawater intake and brine 

discharge systems and port construction activities 

 

Human environment: 

o  Effects of the project on the current lifestyles of local communities 

Studies were completed to identify potential mitigation measures to address the recognized risks.  Mitigations proposed 
include, but are not limited to, community liaison and development programs, construction of settlement by-pass roads, 
implementation of zero-discharge facilities, and reviews of and modifications to infrastructure designs to accommodate 
community and environmental concerns.  

A stakeholder identification study has been completed, and has identified a number of parties will be either directly or 
indirectly affected by project influence.  A number of communication sessions were undertaken during 2012 and 2013, and 
included open houses and meetings, sessions to address specialist interests (such as fishermen); meetings with regional 
authorities, community support service authorities, and professional organizations. 

Community issues identified during these meetings include: 

 
 

 
 
 
 

Job opportunities for local residents during the construction and operation phases of the project 
Decreased quality of life due to increased demand for local supplies of goods and services, housing, and health 
services 
Environmental effects related to mining activities 
Changes to road usages due to by-pass construction and concentrate transport 
Effect of the proposed port facilities on seafood extraction activities 
Effects of seawater intake and brine discharge from the desalination plant. 

 55 

 
 
The Environmental Impact Assessment (EIA) has been completed and was submitted for review and approval on October 
30, 2013.  During the EIA the environmental citizen participation (PAC) process as required by the evaluation process will 
continue.  The citizen participation process with indigenous communities takes into account the special rules that govern 
the consultation and participation processes of such peoples.  Although the lands of the Colla Community of Diego de 
Almagro are not within the direct area of project influence, Capstone will keep lines of communication open for possible 
approaches or inquiries from this community. 

All capital costs are in third quarter 2013 US$.  Capital cost estimates were prepared by the various consultants working on 
the 2014 Feasibility Study and were based on battery limits established by Capstone.  Owner costs were provided by 
Capstone.  Estimates were based on a combination of direct quotes and benchmarking.  The estimate is a Type 3 estimate 
according to AMEC standards (and the Association for the Advancement of Cost Engineering International, AACE), with an 
accuracy of -10 to +15% at the 85% confidence level.  The initial capital cost was estimated at $1,751 M; with an estimated 
sustaining capital cost total of $376.3 M.  The combined initial and sustaining capital costs for the life of mine were 
estimated to be $2,127 M in total (Table 9).

The operating costs are also presented in third quarter 2013 US dollars.  For the copper equivalent estimate, prices of 
$2.85/lb copper and $85.00/t magnetite concentrate were used.  The operating cost estimate is considered to be at a 
feasibility-study level, with an accuracy of -10% to +15%.   Operating costs are summarized in Table 10.

For purposes of the project capital and operating cost estimates, a fixed foreign exchange rate between Chilean Pesos 
(CLP) and US dollars (US$) was initially used.  However, during the DFS estimate development, the foreign exchange rate 
between the CLP and US$ changed appreciably.  To accommodate this change Capstone completed an update to the 
foreign exchange rate for the operating and capital cost estimates.   

 

 

For an updated foreign exchange rate for the development period from 2014 through 2017, Capstone used the 
mean value of the projected CLP to US$ foreign exchange rate from a total of 29 analyst firms compiled by 
Bloomberg (as of May 6, 2014).   
For an updated foreign exchange rate for the operating period from 2018 through 2035, Capstone used an 
algorithm that was developed using the CLP/US$ exchange rate value versus the market sales price of copper.  
This information was gathered over the last 10 years on a daily basis and resulted in the following algorithm: 

CLP/US$ Exchange Rate = -0.0204 (price of Cu in US$/t) + 660.41 

For the 2014 Feasibility Study copper price of US$2.85 (US$6,281/t), this equates to a CLP/US$ rate of 532. 

The exchange rate assumptions are detailed in Table 11.

There were no impacts on the copper hauling operations or G&A as these values were originally estimated in US$.   

The project has been evaluated using an 8% discounted cash flow (DCF) analysis on an after-tax basis.  To reflect the time 
value of money, annual net cash flow (NCF) projections are discounted back to the DFS project valuation date of third 
quarter 2013 using an 8% discount rate.  The discount rate appropriate for the MSD project has been determined using 
several factors, including the type of commodity and the level of project risks (market risk, technical risk and political risk).  
The discounted present values of the cash flows are summed to arrive at the project net present value (NPV).   

An NPV sensitivity analysis was completed using discount rates of 5%, 8% (selected rate), 10%, 12% and 15%.  In addition to 
the NPV, the internal rate of return (IRR) and payback period were also calculated.  In the calculation of IRR it is assumed 

 57 

 
that any intermediate cash flows can be reinvested at the same rate of return.  Cash flows are assumed to occur at the end 
of each period. 

On an after-tax basis, the cumulative net cash flow for the base case is US$3,226.7 million, the IRR is 17.9% and the 
payback period is 4.2 years.  Based on the assumptions made the cash flow analysis shows that the project will generate 
positive cash flows from the first full year of production onwards.  At an 8% discount rate, the after-tax net present value 
(NPV) of the project is US$797.4 million.  The cash flow analysis for the base case is provided in Table 12. 

The after-tax annual and cumulative cash flow are shown in Figure 5.

As stated, the project was evaluated on an after-tax basis with taxes payable in three forms:  

FIGURE 5: PROJECT AFTER TAX CASH FLOW 

 
 
 

Government mining royalty 
First Category corporate income tax 
IVA.   

Since January 1, 2006, mine operators whose annual sales exceed the equivalent 12,000 tonnes of fine copper must pay a 
mining royalty tax.   The mining royalty  is levied on  operating mine income on a  sliding scale between 5% and 14%, 

 58 

  
  
  
  
  
  
  
 
 
depending on operating margins.  The royalty is estimated to be $241.0 M over the LOM and is deductible as an expense 
against corporate tax. 

Corporate income tax consists of the First Category Tax at 20%.  Total First Category Tax payments over the LOM are 
estimated to be $784.2 M.  The 15% Second Category “Additional” Tax was not evaluated for the project.  This Second 
Category Tax is levied on dividend distributions to foreign shareholders. 

An IVA of 19% is applicable to a number of goods and services purchased but this tax is refundable once the mine is in 
operation.  Other than the delay in the recovery of IVA during construction and the impact of the time value of money, the 
LOM net effect of IVA is zero. 

The project evaluation is primarily on an equity funded basis.  Where opportunities to utilize debt capital to fund the 
project are considered, interest shields may reduce the income tax burden of the project, but will require planning to 
consider Chilean thin capitalization requirements and withholding taxes on interest. 

Project investors will need to consider the merits of utilizing a D.L. 600 Foreign Investment Contract (“D.L. 600 Contract”) 
to contribute the capital investment into the project.  A D.L. 600 Contract provides the ability to elect tax invariability 
treatment for the project.  Article 11 ter of D.L. 600 provides foreign investors the right to an invariable mining royalty rate 
for a period of 15 years from the project start date.  Article 11 bis of D.L. 600 allows an investor to elect an invariable 
income tax rate of 42% (versus the 35% combined First and Second Category Tax) for 20 years for a mining project.  
Effective  January  9,  2014,  the  Chilean  Foreign  Investment  Committee  approved  the  D.L.600  Article  11  ter  Foreign 
Investment Contract for the Company’s investment in MSD. 

4 - RISK FACTORS  

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

 59 

 
 
price of copper, lead, zinc, gold, silver and molybdenum 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; 

 
 
 
 
 
 
 
 
 
 
 
  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, silver or molybdenum 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 2015.  Thereafter, approximately 54% is committed under multi-year contracts through 2016 and 21% is 
committed through 2017.  The balance is not currently committed. Fifty percent 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 all of the Company’s gold and silver production from the Minto Mine and all of the 
silver production until April 2017 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 agreements at economic terms, or at all, or that the Company’s 
production will meet the qualitative and quantitative 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, 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.  While the Company does not currently have any foreign currency contracts in place 
to hedge against currency risk, circumstances may arise in the future where this may be an appropriate strategy to manage 
costs and risks. 

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.  
Actual recoveries of copper, lead, zinc, gold, silver and molybdenum 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, silver and/or molybdenum 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. 

 61 

 
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.  The 
Company  completed  the  tender  process  for  Engineering,  Procurement,  Construction  (“EPC”)  and  Engineering, 
Procurement, Construction Management (“EPCM”) packages for project development.  Capstone has selected POSCO E&C 
(“POSCO”) as the preferred EPC fixed price lump sum contractor for the Santo Domingo project.  While the EPC contract 
has not been negotiated or concluded, Capstone has awarded a Limited Notice to Proceed (“LNTP”) to the end of Stage-
Gate 1, which will include confirmation of completeness of the engineering and contractual performance guarantee 
parameters.  This award totals approximately $4.5 million and is part of Capstone’s previously announced 2015 base case 
budget of $16.9 million (of which Capstone’s 70% share is $11.8 million).  This work is expected to be completed before the 
end of the second quarter of 2015.  As a result, if the Company proceeds to development we 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; 
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; 
the availability of power at economic rates 
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. 

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 

 62 

 
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 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 that 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.  

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  we  have  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 

 63 

 
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. 

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 increase our exploration expenses, capital expenditures or production costs or reduce 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, time-consuming and uncertain process. 

Mining companies, including Capstone, 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 on 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  operates  and  limits  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, extending or 
expanding operations or otherwise adversely affect the Company’s business, financial condition, results of operation and 

 64 

 
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 the Water Use Licence are required in order to implement the 
Company’s  planned  mine  expansion.    These  amendments  may  not  be  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 operate 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 periods 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  events  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 extreme adverse 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 

 65 

 
Tahltan or the Kaska may adversely affect the Company’s rights to the Kutcho Project.  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,  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 our 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, 2014, the Company had approximately 1,345 employees and approximately 475 contractors. 

The Company’s workforce is not unionized with the exception of approximately 368 of the hourly employees at the Pinto 
Valley Mine which are represented by six unions, governed by one collective bargaining agreement negotiated by the 
United Steelworkers Union which expired June 30, 2014 and is currently under negotiation.  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 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 

 66 

 
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 not be able 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 joint venture 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 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 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 have 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.

Standard & Poor’s Rating Services assigned Capstone its B+ long-term corporate credit rating and Moody's Investors 
Service assigned Capstone a B1 Corporate Family Rating.  

Credit Facilities 

As at December 31, 2014 Capstone was party to two credit agreements establishing the following credit facilities: 

 

 

A US$200 million Senior Secured Corporate Revolving Term Facility (“RCF”) provided by a syndicate of lenders, 
which matured on October 4, 2017, with $142.8 million outstanding at year end; and 
A US$200 million Senior Secured Reducing Revolving Corporate Credit Facility (“RRCF”), which had a two and a 
half year term from October 2013 and a reduction of the credit limit commencing after six months in equal 
quarterly amounts of $22.2 million.  As of December 31, 2014 $133.3 million was outstanding under this facility. 

The RCF and RRCF contained restrictive and financial covenants as at December 31, 2014, including: 

 

A requirement to maintain a Total Leverage Ratio (total net debt to EBITDA) of less than or equal to 4.0:1.0; a 
Senior Secured Leverage Ratio (senior secured net debt to EBITDA) of 3.0:1.0; and an Interest Coverage Ratio 
(EBITDA to Interest Expense) of 3.0:1.0.  As of December 31, 2014 our ratio of Total Net Debt/EBITDA was 1.3:1.0; 
our  Senior  Secured  Net  Debt/EBITDA  was  0.7:1.0;  and  our  EBITDA/Interest  Expense  ratio  was  19.0:1.0,  for 
purposes of the credit facilities. 

In January 2015 we amended the RCF for up to $500 million and repaid and canceled the RRCF. The RCF now comprises a 
committed $440 million plus a $60 million accordion.  It has a four year term maturing in January 2019 (with extension 
rights on mutual consent), an interest rate of US LIBOR plus 3.0% (adjustable in certain circumstances) and a standby fee of 
0.675%, payable on the undrawn balance of the facility. The $60 million accordion may be exercised by Capstone once 
additional credit is committed from existing and/or new lenders. The old RCF and RRCF were repaid and superseded as 
part of this transaction.  

 

Under the terms of the new RCF, reclamation surety bonds are not classified as indebtedness (up to a value of 
US$150 million) and therefore will not be included in the leverage ratio calculations. Under the new RCF the 
Interest  Coverage  Ratio  (EBITDA  to  Interest  Expense)  was  amended  to  2.5:1.0.   The  pro-forma  covenants 
estimates as of January 31, 2015 under the new RCF (using pro-forma debt and cash figures and 31 December 
rolling EBITDA and Interest figures) are as follows. The estimated ratio of Total Net Debt/EBITDA was 0.77:1.0; the 
estimated Senior Secured Net Debt/EBITDA was 0.78:1.0; and the estimated EBITDA/Interest Expense ratio was 
18.96:1.0.

Each director and officer is appointed for a term of one year which expires on the date of the annual meeting of shareholders of Capstone 
following his or her appointment.  Capstone’s next annual meeting is scheduled to be held on April 29, 2015. 

Ownership of Securities by Directors and Officers 

As at March 16, 2015, the directors and executive officers as a group beneficially owned or exercised control or direction 
over, directly or indirectly, an aggregate of 2,062,518 Capstone common shares, representing approximately 0.54% of the 
issued and outstanding common shares of the Company. 

8.2 

Conflicts of Interest 

Certain of our 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 we may participate, our directors 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 our directors, 
a director who has a conflict abstains 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 Capstone are required to act honestly, in 
good faith and in the best interests of Capstone. In determining whether or we will participate in a particular program and 

 71 

 
 
the interest we will acquired, the directors will primarily consider the degree of risk to which we may be exposed and our 
financial position at that time. See also “Describe the Business - Risk Factors”.

Audit Committee Oversight 

At  no  time  since  the  commencement  of  our  most  recently  completed  financial  year  was  a  recommendation  of  the 
Committee to nominate or compensate an external auditor not adopted by the Board of Directors. 

9.4 

Pre-Approval Policies and Procedures 

The Audit Committee pre-approves all non-audit services provided by our external auditor and has established policies and 
procedures accordingly.  When a new service is proposed by Capstone’s external auditor, management confirms with the 
audit engagement partner that there is no independence concern related to the proposed service.  On the basis that the 
answer to that question is that the proposed service would not impair the external auditor firm’s independence, then the 
matter is raised to the Audit Committee for approval before management proceeds with the proposed service.
