Capstone Makes Contribution in Support of Whitehorse General Hospital

Outpatient Lab to be named in recognition of Capstone and Minto Explorations

VANCOUVER, June 11 /CNW/ - Capstone Mining Corp. ("Capstone") (CS: TSX) and its wholly owned subsidiary, Minto Explorations Ltd. ("Minto"), together with the Yukon Hospital Foundation, announced a long-term partnership with the Foundation at their "Chair-ity" Live Auction event last night. The $55,000 contribution is part of an ongoing commitment by Capstone and Minto to improve the hospital, which provides care to residents of the Yukon and Northern British Columbia, including workers at the Minto Mine and their families.

"Giving back to the communities in which we operate is a priority for all of us at Capstone and our operating subsidiary in the Yukon - Minto," said Stephen Quin, President of Capstone and Minto. "Our employees and their families, our contractors, suppliers, and other residents of the Yukon may all need care from Whitehorse General Hospital at some point in time. We are proud to be able to contribute to the hospital and ensure that they receive the highest level of care possible when they are in need."

"The hospital has many equipment needs, and right now our focus is on purchasing new digital X-ray equipment," said Keith Byram, Chair of the Yukon Hospital Foundation. "This first generous donation from Capstone and Minto will be put towards the purchase of the new digital X-ray equipment. This equipment will vastly improve the diagnostic capabilities at our Hospital. In recognition of their long-term commitment of support, the Outpatient Lab at Whitehorse General Hospital will be dedicated in honour of Capstone and Minto."

An official celebration and dedication of the Outpatient Lab in honour of Capstone Mining and Minto Explorations will take place in the Fall of 2010.

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 a high grade open pit copper-gold mine, and is located in the Yukon, Canada. 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.
