Geo Minerals Completes Geophysical Surveys at the Red Hills and Middle Mountain Porphyry Copper Projects, Arizona

VANCOUVER, BRITISH COLUMBIA, May 11, 2010 (MARKETWIRE via COMTEX News Network) --

GEO MINERALS LTD. (TSX VENTURE: GM) ("GEO" or the "Company") is pleased to announce completion of their geophysical surveys at Red Hills and Middle Mountain, Arizona, with drilling scheduled to target coincident structural and geophysical features. Geo Minerals has two separate option agreements with Inmet Mining Corp. to explore these porphyry copper projects (see news release, Nov. 17, 2009). Inmet has the option to earn a 70-per-cent interest in the Red Hills property and a 70-per-cent interest in the Middle Mountain property by making cumulative cash payments of $675,000 and exploration expenditures of $2-million over five years on each of the projects. Geo Minerals holds its interest in the projects under mining lease and option agreements with Bronco Creek Exploration Inc., a US subsidiary of Eurasian Minerals Inc., with Bronco Creek Exploration Inc. acting as manager for the work programs at both projects.

The Red Hills and Middle Mountain porphyry copper projects are located in a southwest-trending belt of porphyry-copper mineralization that includes operating mines such as Ray, Copper Cities, Miami-Inspiration, Carlotta, and the Resolution deposit with over 20 million tonnes of contained copper (JORC compliant inferred resource of 1,341 Mtonnes @ 1.51% Cu) that is presently under pre-feasibility assessment by Rio Tinto. Drilling in 2009 at Middle Mountain intersected intervals of intense alteration, with zonation consistent with a structural model of a 90 degree rotated and dismembered porphyry copper hydrothermal system. At Red Hills, drilling in 2009 included an intersection of exotic copper oxide mineralization (see news release, Jan. 8, 2009).

Induced polarization (IP) surveys were conducted using the Quantec Titan 24 imaging methodology, which is designed to provide resolution of targets to depths of 700 meters. A total of 36.7 line kilometers were run at Red Hills, and 16.8 line kilometers were completed at Middle Mountain. At Red Hills, three anomalies were identified of which two may merit follow-up drilling. Based on the results of the geophysical surveys and additional geological mapping, 31 additional claims at Red Hills were staked, increasing the property to 253.2 hectares (625.7 acres). At Middle Mountain, three geophysical lines generated a weak to moderate IP anomaly where target rocks were projected to depth using the existing geology and previous drill intercepts. The better anomalies will be tested in a drill program which has been approved and scheduled to begin in the coming weeks.
