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 Company management’s expectations or beliefs regarding future events and include, but are not limited to, statements with respect to the estimation of mineral reserves and mineral resources, the realization of mineral reserve estimates, the timing and amount of estimated future production, costs of production, capital expenditures, success of mining operations, environmental risks, unanticipated reclamation expenses, title disputes or claims and limitations on insurance coverage. In certain cases, forward-looking statements can be identified by the use of words such as “plans”, “expects” or “does not expect”, “is expected”, “outlook”, “guidance”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates” or “does not anticipate”, or “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. In this document, certain forward-looking statements are identified by words including “may”, “future”, “expected”, “intends” and “estimates”. By their very nature forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by the forward- looking statements. Such factors include, among others, risks related to actual results of current exploration activities; changes in project parameters as plans continue to be refined; future prices

  • f resources; possible variations in ore reserves, grade or recovery rates; accidents, dependence on key personnel, labour pool constraints, labour disputes; availability of infrastructure required

for the development of mining projects; delays or inability to obtain governmental and regulatory approvals for mining operations or financing or in the completion of development or construction activities; compliance with debt covenants, 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 actual actions, events or results to differ materially from those described in forward-looking statements, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended. The Company provides no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on 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”, “net debt” are Alternative Performance Measures. Alternative performance measures are furnished to provide additional information. These performance measures are used by management to monitor performance, to plan and to assess the overall 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.

Santo Domingo Project – Development Plan

Decision on if, how, and when to proceed will reflect, among other factors:

  • Ongoing social licence
  • Receipt of port concession
  • General/project specific market conditions
  • Project economics
  • Long-term power availability
  • Awarding project execution contract
  • Financing market
  • Available alternatives
  • 1. Subject to the commercial and regulatory environment in Chile and not within Capstone’s control. Various decisions are dependent on the

availability of low cost power as well as regulatory approval, and clear demonstration of an economically viable project with appropriate financing in place and a supportive environment for development.

Minto North and 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 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 all deposit areas are: Cu=$3.50, Au=$1,300, Ag=$16.00. Resources include any material remaining in the Minto Main Deposit not considered in the current mine plan. 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., is an an employee 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-

  • ff, 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
  • nly 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.
