| Geo Hits 210 Feet (64 Meters) of Copper Mineralization in Arizona |
| VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 8, 2009) - GEO MINERALS LTD. (TSX VENTURE:GM) is pleased to announce the completion of an initial drill test at its Middle Mountain and Red Hills properties, both of which are located in southeast Arizona, approximately 20 km east of the Poston Butte porphyry copper orebody. Based upon observation of reverse-circulation rock chips and surface geology, the Company has drilled into what is interpreted to be the extension of a sulfide-rich, outer portion of a porphyry copper system at its Middle Mountain property and has interesting exotic oxide copper mineralization in gravels adjacent to outcropping mineralization at its Red Hills project. The first-phase drill program at Middle Mountain consisted of two deep reverse circulation drill holes (1000 and 1200 feet (300-360 meters) respectively) and six shallow holes (ranging from 168 to 600 feet (51 to 182 meters)). Intense sericite-pyrite alteration typical of the outer pyritic shell related to a porphyry copper-molybdenum deposit was intercepted in eastern portions of the project area in hole MM-13 at a depth of 680 ft. (207 meters), in MM-19 at 498 ft. (151 meters), and in MM-20 at 80 ft. (24 meters). Sodic-calcic alteration identified in MM-17 and MM-18 in the northwest portion of the property position define the deep flanks of the system and are consistent with the Company's structural model of the hydrothermal system as dismembered and rotated approximately 90 degrees. A follow-up drill program will target more prospective zones of porphyry style mineralization that are covered by shallow gravel deposits to the southwest of the current area of drilling. Sites will be selected among an additional 10 previously permitted drill sites across the target area. Drilling at the Red Hills project targeted a suspected buried porphyry copper deposit west of a large Laramide dike swarm and related copper sulfide mineralization associated with a broad zone of quartz-sericite-pyrite alteration. On a neighboring property controlled by Phelps Dodge, outcropping copper mineralization constitutes a large, non-43-101 compliant low grade resource (500Mt @ 0.1% Cu) and is interpreted to represent the upper, distal portions of a large, rotated and dismembered porphyry copper system. Recent field mapping and re-evaluation of existing geologic data suggest that the hydrothermal system has been rotated approximately 90 degrees. Geo is targeting more prospective portions of the hydrothermal system and higher-grade porphyry-style mineralization that is suspected to lie under gravel cover to the west of current bedrock exposures. A 210-foot (64 meters) zone of exotic copper mineralization developed within the gravel deposits was intersected in RH-2 at a depth of 1840 ft. (560 meters). The zone of exotic copper mineralization and lithologies intersected in the drill hole are interpreted to signify proximity to the buried porphyry copper system. Hole RH-2 did not reach bedrock and was still in exotic copper bearing gravel when the hole was terminated. Subsequent drilling will further delineate the exotic deposit and target porphyry-style mineralization that is believed to lie at shallower depths to the east of the current drill sites. A total of nine sites are currently permitted across the target area for a follow up drill test. Bronco Creek Exploration Inc., the project-generation team from whom the Company optioned the properties, originally identified several large, tilted and dismembered porphyry copper-molybdenum targets at Middle Mountain and Red Hills through surface mapping of porphyry-style alteration and mineralization, analysis of existing geologic maps, geochemical and geophysical data, and reconstructing regional and district structural geology. The technical contents of this release were approved by Geo Minerals director and qualified person as defined by National Instrument 43-101, Marvin Mitchell. Geo Minerals is a junior exploration company actively seeking mineral and energy opportunities for the benefit of all our stakeholders. ON BEHALF OF THE BOARD Michael England, President |
