Three Claims Encompass potential Down Dip and Strike Extensions of High
Grade Mineralization

VANCOUVER, Sept. 8 /CNW/ - Capstone Mining Corp. (CS: TSX) today announced that it and its wholly owned subsidiary, Capstone Gold SA de CV, have entered into a definitive agreement with Golden Minerals Company (AUM:TSX) of Golden Colorado whereby Capstone Gold will acquire three mineral claims immediately adjacent to its Cozamin Mine in Zacatecas State, Mexico. These three claims encompass potential down dip and strike extensions of the mineral resources and mineral reserves in the principal San Roberto area of the mine, as well as the down dip extension of the San Rafael area. The mineral resources and mineral reserves for each of the San Roberto and San Rafael areas are detailed in a news release dated June 1, 2009.

"The acquisition of these three mineral claims immediately adjacent to the Cozamin Mine provides some immediate opportunities for the discovery and definition of additional mineral resources and mineral reserves," said Stephen P. Quin, President & COO of Capstone. "Given the proximity to some of the best mineralization in the San Roberto deposit and the development currently in process in that area, we will begin evaluating this potential shortly. The potential of these claims to host down dip extensions of the San Rafael and the San Roberto mineral resources is an added bonus that we will look to evaluate going forward."

Mineral Claims Acquired

The three mineral claims acquired (San Francisco, Santa Rita and La Esperanza) lie within Capstone Gold's current mineral holdings at the Cozamin Mine and immediately north of the current mining areas. Because the principal Mala Noche vein, which hosts all of the currently known mineral resources and mineral reserves, dips north, the Mala Noche vein crosses on to these claims below the current mineral resources and reserves. Sections identifying the location of these claims relative to the existing mineralization can be accessed on Capstone's website at http://capstonemining.com/s/CozaminPhotos.asp.

Mineral Potential

Capstone Gold has drilled down to the boundary of the San Francisco and Santa Rita in the San Roberto area of the Cozamin mine which hosts the majority of the mineral resources and all of the mineral reserves contained in the June 1, 2009 news release. There is potential for continued down dip extensions of the San Roberto mineralization on to these two claims.
