Capstone Reports Production Guidance for 2010

Forecast Production of 90-100 million pounds of Copper in Concentrates

VANCOUVER, Dec. 17 /CNW/ - Capstone Mining Corp. (CS-TSX) today reported production guidance for 2010 for its Cozamin and Minto mines. Capstone expects to produce 90 million to 100 million pounds of copper in concentrates in 2010 at a total cash cost* of approximately US$1.10 to US$1.20 per pound of payable copper, net of by-product credits and selling costs, based on an exchange rate of C$1.09/US$1.00 and MXP$13.00/US$1.00. Of this production, approximately 55% is projected to come from the Minto Mine and 45% from the Cozamin Mine. This compares to approximately 95 million pounds of copper in concentrates forecast for 2009 at a total cash cost* of approximately US$1.00 per pound of payable copper.

"With both of our mines, Cozamin and Minto, having been through a series of expansions over the past two to three years and now performing at or above design, we are looking forward to another good year in 2010," said Darren Pylot, Vice Chairman & CEO of Capstone. "We are focused on fully optimizing efficiencies and production costs, with the objective of maximizing the profitability of the pounds we produce."

Outlook for 2010

Forecast production for the Cozamin and Minto mines in 2010 is as follows:

Cozamin: Copper production in 2010 is expected to be higher than 2009 now that sustained production is underway from the wider, higher grade portions of the Cozamin deposit. Higher throughput, grades and recoveries are forecast for 2010 as compared to 2009 as a result of continued mill outperformance and sustained access to these wider, higher grade stopes.

Minto: Copper production is expected to be similar to 2009, with increased throughput and a somewhat lower grade forecast for 2010. The increased cash costs reflect lower overall grades.

Production Optimization

With both the Minto and Cozamin mines having experienced some production delays in the third quarter of 2009, 2010 will be a year of optimizing the current operations by stressing efficiencies in operations and costs. Capstone will continue its relentless pursuit of value from its current operations by ensuring production is achieved in a safe and cost efficient manner.

2010 Capital Expenditure Guidance (US$)

Cozamin and Minto capital expenditures for the year are estimated at $12.6 million which includes $3.9 million at Cozamin and $8.7 million at Minto. Included in these amounts are sustaining capital of $3.1 million, mine and mill equipment of $3.8 million, water management and treatment of $2.1 million, community infrastructure development of $2.6 million and $1.0 million in permitting and regulatory costs related to the Phase IV and possible Phase V expansion of the Minto Mine.

Exploration Activities

The principal exploration focus in 2010 is continued exploration drilling at the Minto Mine, where four years of excellent results and significant resource increases show no sign of slowing. Exploration at Cozamin will consist of geophysics, mapping and sampling, as well as evaluating the three newly acquired mineral claims that are within the immediate area of the Cozamin mine resources and reserves. The acquisition of these claims has, opened up potential for the discovery and definition of additional mineral resources in close proximity to the existing mine workings. Estimated exploration expenditures at Minto are C$2.6 million and Cozamin are US$1.0 million, however, such amounts could be increased based on success.
