About Capstone

Capstone owns and operates two high grade copper mines and has an advanced high grade copper-zinc development project, all located in favourable mining jurisdictions in North America. The Cozamin Mine is a high grade, relatively shallow, mechanized underground copper mine in Zacatecas, Mexico, with significant by-product credits of zinc, lead and silver. The Minto Mine is one of the world's highest grade open pit copper-gold mines, and is located in the Yukon, Canada. Both mines have recently undergone significant production expansions and the mines are forecast to produce a total of 90-100 million pounds of copper in concentrate in 2010 at a total cash cost of approximately US$1.10 to $1.20 per pound of payable copper, net of by-product credits and selling costs. In addition, Capstone owns the high grade Kutcho Copper Project in British Columbia, Canada, which is being advanced towards a production decision, and could produce significant by-products of zinc, silver and gold.

Capstone aims to grow both organically through its existing projects, and through mergers and acquisitions. Capstone's growth ambitions are backed up by a successful track record of growth through both avenues, and supported by a strong balance sheet and significant equity investments.

The TSX does not accept any responsibility for the adequacy or accuracy of this press release.

Forward-Looking Information

This document 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 Mining Corp. (the "Company") 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 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", "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. 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 of resources; possible variations in ore reserves, grade or recovery rates; accidents, labour disputes and other risks of the mining industry; delays in obtaining governmental approvals or financing or in the completion of development or construction activities; 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 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. There can be 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.
