This presentation, and the documents incorporated by reference herein, may contain “forward-looking information” within the meaning of Canadian securities legislation and “forward-looking statements” within the meaning of the United States Private Securities Litigation Reform Act of 1995 (collectively, “forward-looking statements”). These forward-looking statements are made as of the date of this document and Capstone does not intend, and does not assume any obligation, to update these forward-looking statements, except as required under applicable securities legislation. Forward-looking statements relate to future events or future performance and reflect our expectations or beliefs regarding future events. Forward-looking statements include, but are not limited to, statements with respect to the estimation of mineral resources and mineral reserves, the realization of mineral reserve estimates, the timing and amount of estimated future production, costs

  • f production and capital expenditures, the success of our mining operations, environmental risks, unanticipated reclamation expenses and title disputes. In certain cases, forward-looking

statements can be identified by the use of words such as “plans”, “expects”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates”, “believes” or variations of such words and phrases, or statements that certain actions, events or results “may”, “could”, “would”, “might” or “will be taken”, “occur” or “be achieved” or the negative of these terms or comparable

  • terminology. By their very nature, forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements

to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. Such factors include, amongst others, risks related to inherent hazards associated with mining operations, future prices of copper and other metals, compliance with financial covenants, surety bonding, our ability to raise capital, counterparty risks associated with sales of our metals, use of financial derivative instruments and associated counterparty risks, foreign currency exchange rate fluctuations, changes in general economic conditions, accuracy of mineral resource and mineral reserve estimates, operating in foreign jurisdictions with risk of changes to governmental regulation, compliance with governmental regulations, compliance with environmental laws and regulations, reliance on approvals, licences and permits from governmental authorities, impact of climatic conditions on our Pinto Valley, Cozamin and Minto operations, aboriginal title claims and rights to consultation and accommodation, land reclamation and mine closure obligations, uncertainties and risks related to the potential development of the Santo Domingo Project, increased operating and capital costs, challenges to title to our mineral properties, dependence on key management personnel, potential conflicts of interest involving our directors and officers, corruption and bribery, limitations inherent in our insurance coverage, labour relations, increasing energy prices, competition in the mining industry, risks associated with joint venture partners, our ability to integrate new acquisitions into our operations, cybersecurity threats and other risks of the mining industry as well as those factors detailed from time to time in the Company’s interim and annual financial statements and management’s discussion and analysis of those statements, all of which are filed and available for review under the Company’s profile on SEDAR at www.sedar.com. Although the Company has attempted to identify important factors that could cause our actual results, performance or achievements to differ materially from those described in our forward- looking statements, there may be other factors that cause our results, performance or achievements not to be as anticipated, estimated or intended. There can be no assurance that our forward- looking statements will prove to be accurate, as our actual results, performance or achievements could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on our forward-looking statements.

Alternative Performance Measures

“C1 cash cost”, “cash cost”, “all-in sustaining cost”, “all-in cost”, “fully-loaded all-in cost”, “adjusted net earnings/loss”, adjusted EBITDA”, “operating cash flow before changes in working capital” and “net debt” are Alternative Performance Measures. Alternative performance measures are furnished to provide additional information. These non-GAAP performance measures are included in this presentation because these statistics are key performance measures that management uses to monitor performance, to assess how the Company is performing, to plan and to assess the

  • verall effectiveness and efficiency of mining operations. These performance measures may not be comparable to similar data presented by other mining companies. These performance

measures should not be considered in isolation as a substitute for measures of performance included in the Company’s unaudited condensed interim consolidated financial statements prepared in accordance with IFRS.

Notes: Consolidated Mineral Reserve Estimate

NOTES: Mineral Reserves take into account mining activities (where applicable) until January 1, 2016. Gregg Bush, P.Eng., Senior Vice President and Chief Operating Officer at Capstone, is the Qualified Person for the disclosure of Capstone's consolidated Mineral Reserves table. Rounding as required by reporting guidelines may result in apparent summation differences between tonnes, grade and contained metal content. All Mineral Reserve estimates are inclusive of dilution and mining recovery factors. Contained ounces (oz) are troy ounces. COG is cut-off grade. NSR is net smelter return. All amounts in US$ unless otherwise

  • specified. Stockpiled material is treated as Proven Mineral Reserves. See Technical Reports filed under Capstone’s profile on SEDAR for further information.
  • 1. John Marek, PE, SME-RM, of Independent Mining Consultants, Inc., is an independent Qualified Person responsible for the preparation of the Mineral Reserves estimate with an effective date of January 2016.

Economic inputs to the block model were USD$2.75/lb per pound copper, USD$12.75/lb Molybdenum. Cut-off Grade – variable between 0.17% Cu to 0.18% Cu through the LOM. The minimum mill feed cut-off grade is 0.17% Cu, but in years where sufficient higher grade mill feed is available, the mill cut-off grade may be higher, resulting in material between the yearly mill cut-off grade and 0.18% being stockpiled. The additional 0.01% from 0.17% to 0.18% is to cover the additional cost of rehandling material from the stockpile to the mill. Material between 0.17% to 0.18% that is not fed directly to the mill is not stockpiled as it cannot pay for the mining re-handling cost at the price assumptions used. Proven mineral reserves include an additional 323 kt of stockpiled material not considered in the Pinto Valley Mine Life Extension - Phase 3 (PV3) Pre-Feasibility Study NI 43-101 Technical Report.

  • 2. Gregg Bush, P.Eng., Senior Vice President and Chief Operating Officer at Capstone, is the Qualified Person responsible for the disclosure of the Cozamin Mine Mineral Reserves taking into account ongoing mine
  • production. Mel Lawson, SME-RM, and Allan Schappert, SME-RM, of Stantec Consulting International LLC, are independent Qualified Persons responsible for the preparation of the San Roberto zone Mineral

Reserves estimate with an effective date of December 31, 2013. Metal prices used in the San Roberto reserve estimate for copper, silver, zinc, and lead, respectively, are $2.50/lb, $20/oz, $0.80/lb, and $0.85/lb. Processing recoveries were Cu=92%, Ag=72%, Zn=69%, Pb=64%. The exchange rate used is MEX12.50 to US$1.00. Allan Schappert, SME-RM, of Stantec Consulting International LLC, is an independent Qualified Person responsible for the preparation of the Mala Noche Footwall Zone Mineral Reserves estimate with an effective date of September 30, 2015. Metal prices used in the MNFW zone reserve estimate for copper, silver, and zinc, respectively, are $2.50/lb, $14/oz, $0.80/lb, and $0.85/lb. Contribution from Pb was not considered because a Pb concentrate will not be produced during 2016. Processing recoveries were Cu=94%, Ag=58%, and Zn=72%. A NSR COG of $42.50/t was used for the San Roberto and MNFW zones. The exchange rate used is MEX16 to US$1.00.

  • 3. Pooya Mohseni, P.Eng., Chief Engineer at Minto, is the Qualified Person responsible for the disclosure of the Minto Mine Mineral Reserves taking into account ongoing mine production, in addition to the

preparation of the Mineral Reserves estimate of the Minto deposits. The open-pit Mineral Reserves estimate at Minto North has an effective date of January 1, 2011. The Mineral Reserves estimates for MSD (Area 2 open pit, Area 2/118 underground, Copper Keel underground) and Minto East underground have an effective date of December 31, 2015. Metal Price assumptions used to calculate the NSR COG for all deposits are: Cu=$2.50, Au=$300, Ag=$3.90. Processing recoveries for all deposits are: Cu=91%, Au=70%, Ag=78%. Open pit mineral reserves are reported above 0.5% Cu COG. Underground mineral reserves are reported above a $64.40 NSR COG.

  • 4. Santo Domingo Project Mineral Reserves shown on 100% basis (Capstone’s share is 70%). Carlos Guzman, FAusIMM, CMC, of NCL Ingeniería y Construcción SpA, is the independent Qualified Person responsible

for the preparation of the Mineral Reserves estimate with an effective date of May 2, 2014. 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 $2.75/lb Cu, $1,275/oz Au and $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 $70/dmt, $0.07/lb of Cu refining charges, $5/oz of Au refining charges, $48/wmt and $3/wmt for shipping Cu and Fe concentrates respectively; waste mining cost of $1.53/t, mining cost of $1.53/t ore, and process and G&A costs of $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. There have been no mining activities at Santo Domingo since the release of the NI 43-101 Technical Report.

  • 5. Michael Makarenko, P.Eng., is an independent Qualified Person responsible for the preparation of the Kutcho Mineral Reserves estimate with an effective date of February 15, 2011. Mineral Reserves are

reported within 1.0% Cu grade shells used for stope design. There have been no mining activities at Kutcho since the release of the NI 43-101 Technical Report.

  • 3. Douglas McIlveen, P.Geo., Chief Geologist at Minto, is the Qualified Person responsible for the disclosure of the Minto Mine Mineral Resources taking into account ongoing mine production. Garth Kirkham, P.Geo.,

FGC, of Kirkham Geosystems Ltd., is an independent Qualified Person responsible for the preparation of the Mineral Resources estimates for the Minto North, Minto East, and Minto East 2 areas. The drilling data cut-off date for Minto North of December 1, 2009. The Minto East and Minto East 2 areas were reesimated with an effective date of May 31, 2015. Dr. Wayne Barnett, Ph.D., P.Geo., of SRK Consulting (Canada) Inc., is an independent Qualified Person responsible for the preparation of the Mineral Resources estimate at Ridgetop that takes into account drillhole data until August 2010, and the MSD deposit, which includes the Area 2/118, Wildfire, and Copper Keel areas. The MSD Mineral Resource estimate has an effective date of May 31, 2015. Minto North and Ridgetop areas are amenable to open pit extraction. Area 2/118 and Wildfire areas are amenable to open pit and underground mining, while Minto East, Minto East 2, and Copper Keel areas are suitable for underground mining. Mineral Resources are reported above a 0.5% Cu COG. Metal price assumptions used to determine the COG for reasonable prospects of economic extraction for the MSD area are: Cu=$2.85, Au=$900, Ag=$12.00, and for all deposit areas are: Cu=$3.50, Au=$1,300, Ag=$16.00. Resources exclude material mined but not processed during pre-stripping activities in the Area 2 region of MSD and currently held in stockpiles.

  • 4. Santo Domingo Project Mineral Resources shown on 100% basis (Capstone’s share is 70%). David Rennie, P.Eng., of Rosco Postle Associates Inc. and an independent Qualified Person responsible for the

preparation of the Mineral Resources estimates for the Santo Domingo Sur, Iris, and Iris Norte deposits, which have an effective date of August 31, 2012. Mineral Resource estimates for the Estrellita deposit have an effective date of October 30, 2007. Mineral Resources for the Santo Domingo Sur, Iris, and Iris Norte deposits are reported using a COG 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 to metal price units; R is metallurgical recovery and %Cu Equivalent = (Cu Value + Au Value + Fe Value)/(Cu Value per 1%Cu). An assessment of reasonable prospects for economic extraction 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

  • f 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. Mineral Resources for the Estrellita deposit are reported using a 0.3% Cu COG.
  • 5. Garth Kirkham, P.Geo, FGC, is an independent Qualified Person responsible for the preparation of the Mineral Resources estimates with an effective date of February 15, 2011. Mineral Resources are reported

above a 1.5% Cu COG.
