Pinnacle Completes I.P. Survey at La Calavera Copper-Zinc Property, Mexico

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 21, 2007) - PINNACLE MINES LTD. (TSX VENTURE:PNL)(FRANKFURT:O7M) is pleased to report exploration progress on its La Calavera copper-zinc property in the State of Oaxaca, Mexico. The Company has completed 12,000 meters of a induced polarization-resistivity survey in ten lines on 100 meter spacing. The survey is oriented with east-west lines across potential Cretaceous carbonate host rocks that are in contact with a Tertiary granodiorite (mineralizer). Oxidized skarn mineralization is present locally at the surface. Geologic mapping suggests granodiorite sills are present with skarn mineralization developed in adjacent limestone in contact above and below the sills. The large La Calavera property consists of two concessions totaling 8,267 hectares and is immediately adjacent to the Cobre Grande property controlled by Linear Metals Corp.

I.P.-resistivity results have generated strong targets outward from the main granodiorite intrusive in prospective host rocks covering an area over 1000 meters long and 750 meters wide. Initial road access into the area is being developed. Drill targets have been identified and the drilling of vertical holes to 300+ meters will commence when all permitting has been completed.

Jeffrey L. Wilson is the qualified person under National Instrument 43-101 who is in charge of the exploration program on behalf of Pinnacle.

Pinnacle Mines Ltd. is a Canadian based mineral exploration company with assets in Canada and Mexico. In Canada, Pinnacle holds several properties in Northwestern British Columbia in close proximity to numerous past and producing mines including the Silbak-Premier Mine and Barrick Gold's famed Eskay Creek Mine.

Respectfully Submitted,

Jeffrey L. Wilson, Vice President Exploration
