VANCOUVER, December 6, 2010 /PRNewswire-FirstCall/ --

- Operating Activities to Ramp Up to Full Production Over the Next Several Days

Capstone Mining Corp. (CS: TSX) today reported that operating activities at its Cozamin Mine recommenced on a limited scale on the morning of Friday December 3. Production levels are expected to ramp up to Cozamin's nominal design capacity of 3,000tpd over the next week to 10 days, extracting ore from areas outside of the Avoca stopes. Limited mining in the Avoca stopes will resume in January and is expected to return to full capacity in February 2011, after the completion of measures to ensure the stability of the zone and the safety of our employees. The addition of production from the Avoca stopes should allow production at Cozamin to be sustained at design capacity, as has been the situation for extended periods in 2010. This return to production follows an evaluation of the geotechnical stability of the areas of the mine currently being worked by Capstone's staff and independent mining and geotechnical consultants, which review will extend into the Avoca area before production resumes from those areas.

"We are taking appropriate and measured steps to return our Cozamin Mine to normal operations," said Gregg Bush, COO of Capstone Mining Corp. "The tragic accident that occurred last week warrants a continued high degree of caution in our approach to the mining of the Avoca area and we are utilizing both the experience of our staff and that of independent consultants to ensure the stability of the mining areas and the safety of our personnel."

Capstone is committed to the highest safety standards at each of its operations. With the assistance of independent geotechnical and mining consultants, Capstone is conducting reviews of each of the areas of the mine and will ensure that any additional safety measures are fully implemented before activities resume in any area. The operations are expected to return to full capacity over the next several days. This accident has obviously affected the production for the Cozamin Mine and Capstone's ability to meet its guidance objectives for 2010, but the safety of Capstone's personnel comes first. The anticipated range of production for 2010 is estimated at 37-38 million pounds of copper in concentrates, but with increased by-product production as ore is extracted from areas with higher lead and zinc grades. The actual production achieved will depend on the rate of return to full production.

As a result of this revised production plan for the Cozamin Mine, Capstone anticipates that it will not meet its amended guidance of 80-85 million pounds of copper in concentrate in 2010, but some of the revenue lost as a result of producing from lower copper grade areas at Cozamin should be offset by higher lead and zinc production from these areas. Depending on the timing and rate of ramp up and the performance of the Minto Mine, production guidance is provisionally amended to 78-80 million pounds of copper in concentrate in 2010.
