- The resource update yields a 47% increase in tonnage with a 51% increase in contained copper and 54% in contained silver.

- The Measured and Indicated categories increase to 5.5 million tonnes containing 287 million pounds of copper, 131 million pounds of zinc, 47 million pounds of lead and 15.2 million ounces of silver.

- The Inferred category increases to 3.1 million tonnes containing 170 million pounds of copper, 80 million pounds of zinc, 16 million pounds of lead and 8.7 million ounces of silver.

- The resource reflects the tonnes mined as of August 31, 2007.

UPDATED COZAMIN RESOURCE YIELDS INCREASED TONNAGE

This new resource estimate significantly increases both the tonnage and contained metal within all of the resource categories, while maintaining its high grade. The following table shows the break down of resources at a 1% copper cut-off.

This new resource estimate has been completed by qualified person Michelle Stone, P.Geo., Ph.D., of Capstone Mining Corp., Vancouver, B.C. This estimate is based on an updated 3D geologic model integrating an additional 26,266 metres of diamond drilling including 5,828 assays from 5 surface and 70 underground NQ-core drill holes and 6,954 underground chip channel samples collected in 2006 and 2007. These data augmented the 25,325 meters of drilling in 37 surface and 66 underground core holes and 1,103 underground chip channels samples used in the 2006 resource estimate. Grades for the model were estimated using the inverse distance squared (ID2) method from 2 metre composited intervals within the copper sulphide zone, and the mineralized hangingwall and footwall.

Resource tables and drill intercepts locations related to the above totals for the updated Cozamin resource estimate will be available on the Company's website www.capstonemining.com.

A technical report on the Cozamin Mine Project will be filed with SEDAR within 45 days.

The Company has already commenced a program of underground infill drilling to upgrade the inferred resources. In addition, the Company plans to undertake both surface and underground drilling in 2008 to explore along strike and down dip of the updated resources.
