Pro Minerals Inc.: Phase Two of Exploration Complete, Cairo Gold Project

VANCOUVER, 09/23/11 - Pro Minerals Inc. (TSX VENTURE: PRM) is pleased to announce that the Company has completed Phase Two of exploration on its 100% owned Cairo Gold Project situated near Matachewan, Ontario. In this phase, a leading edge XDS VLF-EM airborne survey was flown over 570 line kilometres. The technology utilized high sensitivity and horizontal gradient magnetics. The survey was flown by Terraquest Ltd. at 100 metre intervals in two directions (north-south and east-west) to provide detailed information with respect to certain geological structures located on the claims.

Initial results indicate a number of high priority anomalies which the Company anticipates will correspond with available geological data. All results from the survey are now being carefully interpreted and will form the basis for an exploration program planned on the property.

Further, Pro Minerals has staked an additional four claims totaling 736 hectares (1,818 acres) claims represented the 'Whiskyjack' zone.

Pro Minerals' Cairo Gold Project is located approximately 46 kilometres west of Kirkland Lake, and and now totals an area of 2,450 hectares (6,128 acres). The Cairo Project is ideally situated just 5 kilometres northeast of the Young Davidson Mine, which was recently opened by Northgate Minerals Corporation. The Young Davidson currently has the 6th largest gold reserve in Canada, with 2.8 Million ounces of gold. The Cairo Gold Project and Young Davidson mine are both situated in the southwestern section of the Abitibi Greenstone Belt. The Abitibi is one of the largest greenstone belts in the world and host to 160 Million ounces of gold from both historic and present production. The Cairo Gold Project is easily accessible and close to infrastructure including rail, roads, water, power and labor force.
