Capstone Mining Provides Update on Pinto Valley Acquisition

VANCOUVER, June 11, 2013 /CNW/ - On April 28, 2013, Capstone Mining Corp. ("Capstone") (TSX: CS) announced it entered into an agreement with BHP Copper Inc., a subsidiary of BHP Billiton Ltd. ("BHP Billiton"), to purchase the Pinto Valley copper mining operation and the associated San Manuel Arizona Railroad Company in Arizona, USA for US$650 million (the "Transaction").

The Transaction has been granted approval to proceed by the U.S. Federal Trade Commission ("FTC") under the Hart-Scott Rodino Antitrust Improvements Act.

In addition, the restart of the Pinto Valley Mine is progressing according to plan. As of May 27, 2013, throughput over a 20 day period during the month of May averaged approximately 49,100 tonnes per day at an average grade of 0.33% copper, producing approximately 6.5 million pounds of copper. Copper recovery averaged 84.2%, producing a copper concentrate with an average grade of 29.0%.

"We are very pleased that the restart of the Pinto Valley operation is proceeding well and according to plan," said Darren Pylot, President and CEO of Capstone. "The successful restart and FTC approval are two important steps towards closing of the Transaction."

"The most significant remaining condition is the transfer of the operating permits, which is in progress," continued Mr. Pylot. "Once those transfers are completed we would anticipate proceeding quickly to close the Transaction, which we expect will take place in the third quarter of 2013."

Also, in connection with the Transaction, Capstone expects to file its National Instrument 43-101 compliant technical report by June 13, 2013, related to the 968 million tonne Measured and Indicated Mineral Resource, announced on April 28, 2013. The Transaction remains subject to customary closing conditions and there can be no assurance such conditions will be met or that the Transaction will close.

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 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.
