(TSXV: GR) (the \"Company\" or \"Great Atlantic\") is pleased to announce it has received two 2010 metallurgical reports for the Golden Promise Gold Property, located in the central Newfoundland gold belt. The property is 100% owned by its wholly owned subsidiary, Golden Promise Mines Inc. The reports document 2010 scoping level metallurgical test work by SGS Canada Inc. (SGS) on Jaclyn Main Zone samples for Crosshair Exploration and Mining Corporation, who was the owner of the Golden Promise Property at that time.

Highlights for this include (Lang and Ratnayake, 2010):The total weight of the sample received by SGS was 34.4 kilograms. The calculated head grade was 4.5 grams / tonne (g/t) gold (analysis by screened metallics). A gravity separation test conducted on a 10-kilogram sample ground to K80 of 120 microns, recovered 85% of the gold. The conclusion was that this is a benefiting process for the recovery of gold from the resource material. The recovery process was further enhanced when the gravity tail was ground to K80 of 70 microns and leached. Leaching recovered 93.6% of the gold in the gravity tail, projecting the combined gravity/leach gold recovery to 99.0%.Similar benefits were proven when the gravity tail was ground to K80 of 110 microns, and floated. In the floatation test, 95.7% of the gold in the gravity tail was recovered to a rougher concentrate of 6.4% mass, projecting the combined recovery of gravity/flotation circuit to 99.4% gold. Leaching the flotation tail recovered 65.6% of the gold in the flotation tail. The report stated this test proved to be unnecessary as the gold available in the feed to the leach circuit was low and could...
