BRITISH COLUMBIA – Vancouver-based Commerce Resources has filed a 43-101 report for the Upper Fir deposit at its Blue River project in the Kamloops Mining District. The company used a 175-g/t Ta2O5 cutoff to estimate an indicated resource of 7.38 million tonnes grading 217 g/t Ta2O5 and 1,1202 g/t Nb2O5. By the same measure, the inferred resource is 16.49 million tonnes grading 2.13 g/t Ta2O5 and 1,222 g/t Nb2O5.

The resources in the Upper Fir deposit comprise a series of sill-like carbonatite bodies with an estimated true thickness of 91.2 metres. The deposit is known to extend more than 1,450 metres north-south and up to 800 metres east-west. The company noted that the mineralization includes pyrochlore and ferrocolumbite, present as microscopic grains as well as composite grains that exceed 1.0 cm in diameter.
