Greg Klein reports that with a standout interval of 19.71% total rare earth oxides over 0.82 meters, the last two holes from Commerce Resources winter/spring season continued the Ashram deposit pattern of high grades close to surface. The infill drilling comprised part of a 31-hole, 4,146-meter program to upgrade the northern Quebec project resource for a pre-feasibility study. The latest assays show:

Hole EC15-135

2% total rare earth oxides, 4.6% middle and heavy rare earth oxides and 4.1% fluorite over 22.31 metres, starting at 9.62 metres in downhole depth

19.71% TREO, 3.5% MH-T and 2.2% fluorite over 0.82 metres, starting at 62.53 metres

2.83% TREO, 3.6% MH-T and 0.6% fluorite over 10.62 metres, starting at 175.14 metres
Hole EC15-138

1.67% TREO, 7.7% MH-T and 8.6% fluorite over 155.45 metres, starting at 5.18 metres
(including 1.85% TREO, 6.9% MH-T and 9.2% fluorite over 89.99 metres)
(which includes 2.03% TREO, 6.2% MH-T and 10.5% fluorite over 21.43 metres)
(and also includes 2.01% TREO, 6.3% MH-T and 9.9% fluorite over 36.61 metres)

Commerce Resources continues near-surface high grades at Ashram Summer drilling continues, one of a number of measures that bring Ashram closer to pre-feasibility.
Commerce estimates true widths at 50% to 70% along the deposit margins, increasing to 100% as intersections approach the deposit center. For purposes of the pre-feasibility study, drilling stopped within a pre-determined depth, with EC15-138 ending in 2.06% TREO. This batch included a third hole drilled for hydrogeological studies.

While the grade of 19.71% TREO does not reflect Ashram as a whole, Commerce stated that it highlights the potential for coarse-grained, higher-grade pockets of REE mineralization to occur at relatively shallow depths.

Commerce also holds the Blue River tantalum-niobium project in southeastern British Columbia, which has a 2011 preliminary economic assessment.
