Friday August 8, 9:40 am ET

VANCOUVER, Aug. 8 /CNW/ - Commerce Resources Corp. (TSXv: CCE) (FSE: D7H) ("the Company") is in receipt of an updated resource estimate for the Upper Fir Carbonatite, located in east-central British Columbia.

The updated resource estimate is based upon 20 HQ diameter diamond drill holes completed during 2005-2006, and an additional 18 HQ diameter diamond drill holes completed during 2007. The holes outlined a series of sill-like bodies with up to 100 m total thickness, that extends for more than 1,100 m in a north-south direction and up to 600 m in an east-west direction. The carbonatite remains open both to the east and to the south.

Based on the exploration from 2005-2007, the Upper Fir Carbonatite is estimated to contain an indicated resource of 14.68 Mt with average grades of 190 g/t Ta(2)O5 (Tantalum) and 1,300 g/t Nb(2)O5 (Niobium), within a 38 m confidence limit. In addition, the mineralized body is estimated to contain an inferred resource of 19.8 Mt with average grades of 188 g/t Ta(2)O5 and 1,612 g/t Nb(2)O5, within a 100 m confidence limit. When using higher grade cut-offs of 200 g/t Ta(2)O5, the average tantalum grades increase to 231 g/t for the indicated portion and 225 g/t for the inferred portion. Other details are as follow:
