Exploration Drilling Commences At Cozamin Mine 

VANCOUVER, BC - Capstone Mining Corp. reported that it has commenced exploration diamond drilling at its Cozamin Mine in Zacatecas State, Mexico . The immediate focus for this drilling is to explore areas along the Mala Noche vein system (which hosts all of the current mineral resources and mineral reserves at the Cozamin mine) that are in close proximity to the current workings and existing mine infrastructure. A second phase of drilling is planned for later in the year to test targets that lie off the Mala Noche vein structure, and away from the mine workings. Exploration expenditures at Cozamin are forecast to total US$3 million in 2010.

Limited drilling has already been conducted on one target located in the footwall of the Mala Noche vein, adjacent to the current production areas, called the "Mala Noche Footwall Zone". Using a small diamond drill owned by the mine, several significant intercepts of copper mineralization have already been located. A second high priority target lies immediately east of the Avoca stopes currently being mined, where mineral reserve grades and thicknesses are greatest. This target lies beyond the limits of the current mineral resources and mineral reserves, which have an artificial boundary at a historic claim boundary, on claims that were purchased. "Four priority targets in close proximity to our Cozamin Mine will be drill tested in the coming months," said Stephen P. Quin, President & COO of Capstone Mining. "These targets represent the first of a number of targets generated from a sustained 12-month property-wide assessment of the exploration potential of the Cozamin Mine property and suggest significant potential for the discovery of new mineral resources within the principal known vein system that hosts all the currently known mineral resources and mineral reserves, as well as in parallel hydrothermal systems."
