VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 30, 2010) -GEO MINERALS LTD. (TSX VENTURE:GM)(FRANKFURT:8G3) ("GEO" or the "Company") announces mobilization for its drilling program with Inmet Mining Corp at the Middle Mountain porphyry copper property in south central Arizona has commenced. Brown Drilling (Kingman, Arizona) has been contracted to complete three initial test holes of 600 meters each (~2,000 feet) using a combination of reverse-circulation and core drilling methods to test for porphyry copper mineralization believed to be present in extended and tilted structural blocks beneath shallow gravel cover and outcrops exhibiting intense alteration and quartz-sulfide veining.

The targets are defined by an induced polarization/resistivity (DC/IP) geophysical survey recently completed by the Company (see news release, May 11, 2010), in combination with surface geological mapping. Previous drilling by the Company on the eastern portion of the property included three drill holes that intersected intense sericite-pyrite alteration typical of the outer pyritic shell of a porphyry copper-molybdenum deposit at depths of 207 meters (680 ft.), 151 meters (498 ft.), and 24 meters (80 ft) (see news release, Jan. 8, 2009).

The program is expected to take approximately 35 days, after which the drill rig will mobilize to the Company's Red Hills porphyry copper project, located seven kilometers north of Middle Mountain.

GEO has an option agreement with Inmet Mining Corp. to explore the Middle Mountain porphyry copper project, with GEO holding its interest under a mining lease agreement with Bronco Creek Exploration Inc. (see news release, Nov. 17, 2009). Bronco Creek Exploration is acting as manager for the work programs at Middle Mountain.
