Capstone Mining Completes Acquisition of Pinto Valley Mining Operations

Vancouver, British Columbia - Capstone Mining Corp. ("Capstone") (TSX: CS) has completed the previously announced acquisition of the Pinto Valley copper mine and the associated San Manuel Arizona Railroad Company from BHP Copper Inc., a subsidiary of BHP Billiton Ltd. ("BHP Billiton").

"The closing of the Pinto Valley acquisition advances us as one of the leading intermediate copper producers, with a focus in the Americas," said Darren Pylot, President and CEO of Capstone. "Following the closing of the transaction, we have retained considerable financial flexibility with a very conservative capital structure."

The purchase price of US$650 million was funded from cash and Capstone's credit facilities.


The restart of the Pinto Valley Mine, which commenced in December 2012, is continuing with a targeted run-rate of 50,800 tonnes per day by the end of 2013 with annualized production of 130 million to 150 million pounds of copper per year.

Capstone will commence reporting full operating and production information for Pinto Valley with its fourth quarter report.

An experienced workforce remains in place, with 98% of Pinto Valley's 650 employees accepting Capstone's offer of employment, including all key positions. Steve Winkelmann, formerly Capstone's VP of North American Operations, has been appointed Pinto Valley's Mine General Manager and has been on site shadowing his BHP Billiton counterpart since early September. Steve has 40 years of mining experience including large mining operations, primarily in the US and most recently in Arizona.

Next Steps

The Capstone Pinto Valley team will initially focus on continuing to ramp up production levels and the integration of the operations to achieve our targets. At the same time leadership will identify opportunities for cost reduction, reliability enhancement and throughput maximization.

Capstone believes that considerable potential exists to upgrade the existing 968 million tonnes of Measured and Indicated ("M&I") Mineral Resources (grading 0.35% copper at a 0.25% cut-off grade) into reserves, potentially extending the operation beyond the current reserve life as reported by BHP Billiton. A Preliminary Feasibility Study ("PFS") is underway that will target the M&I Mineral Resources for potential conversion to reserves, with expected completion in late 2013 or early 2014. The PFS will consider the potential to extend operations within the currently permitted boundaries. In addition, Capstone plans to commission engineering and economic studies to consider all remaining current mineral resources and their potential for development.

Cautionary Note to United States Investors

This news release contains disclosure that has been prepared in accordance with the requirements of Canadian securities laws, which differ from the requirements of U.S. securities laws. Without limiting the foregoing, this news release refers to a technical report that uses the terms "indicated" and "inferred" resources. U.S. investors are cautioned that, while such terms are recognized and required by Canadian securities laws, the SEC does not recognize them. Under U.S. 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. U.S. investors are cautioned not to assume that all or any part of indicated resources will ever be converted into reserves. U.S. investors should also understand that "inferred resources" have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. It cannot be assumed that all or any part of "inferred resources" will ever be upgraded to a higher category. Therefore, U.S. investors are also cautioned not to assume that all or any part of inferred resources exist, or that they can be mined legally or economically. Accordingly, information concerning descriptions of mineralization and resources contained in this news release may not be comparable to information made public by U.S. companies subject to the reporting and disclosure requirements of the SEC.
