General Minerals Corporation Initiates Exploration Program in Northern Mexico and Establishes Mexican Subsidiary Company

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Sept. 15, 2005) - General Minerals Corporation ("GMC") (TSX:GNM) is pleased to announce that it has now established a subsidiary company in the northern State of Sonora, Mexico and has staked six properties covering approximately 9,600 hectares. The name of the new company is Minera Genminmex S.A. de C.V. Initial results from geology and sampling in recent months are encouraging, with a large copper, gold-bearing, "porphyry related", tourmaline-sericite hydrothermal system being mapped at one site. Grab samples have assayed up to 4 gpt gold, with anomalous copper and other metal values. The assay work on the grab samples was performed by the ALS Chemex laboratory in Vancouver, BC using the Atomic Absorption and Fire Assay methods. The ALS Chemex laboratory is a ISO 9001 certified facility. Another property exhibits several square kilometers of quartz-sericite-pyrite alteration and scattered copper showings. Other land positions are gravel-covered, pediment exploration targets with varying amounts of favorable geochemical and geological features in adjacent outcrop. The Company moved into northern Mexico because the good "porphyry copper" geology found in Arizona and New Mexico does not stop at the US border with Mexico, and because the Company was fortunate enough to be able to put together a superior team of geologists/landmen experienced in the geology and exploration of the region. The team is headed up by Dr. William A. Rehrig, who has had considerable exploration experience and success in the state of Sonora, Mexico where GMC is currently focusing its efforts.

Ralph Fitch, President of GMC, stated that "...we have felt that an exploration program in northern Mexico is a natural extension of our experience and success with our program in southern Arizona. We now have the two joint ventures with Teck Cominco and BHP Billiton on our porphyry copper prospects in southern Arizona at the Monitor and Dragoon properties, respectively. Our experience in the region now coupled with the experience of Bill Rehrig places us in an excellent position to develop properties of merit in Mexico. We will continue with our plan of then showing the properties at the appropriate stage of exploration to prospective joint venture partners."

General Minerals Corporation is an international minerals exploration company focusing its activities in North and South America. The Company has six properties in the US, three in Bolivia, one in Chile, as well as the six properties in Mexico. The target mineralization is copper, silver and gold. The Company currently has four properties that are under option to other companies: Malku Khota (Bolivia) with SILEX Bolivia S.A., a Bolivian subsidiary of Apex Silver Mines Ltd.; Escalones (Chile) with the Phelps Dodge Chilean subsidiary, Minera Aurex (Chile) Limitada; Monitor (USA) with Teck Cominco Ltd.; and Dragoon (USA) with BHP Billiton. The Company also assists other groups of entrepreneurial geologists through equity investment to form companies and develop early stage exploration projects with discovery potential. Two of these companies, Foundation Resources Ltd. and Afghan Minerals Inc., were established in 2004 where the primary country focus has been in Mongolia and Afghanistan, respectively.
