Commerce Resources’ rare earths metallurgy optimized by university lab

by Greg Klein | August 1, 2019

Successful methods applied in separate laboratories further demonstrate the amenability of a Quebec rare earths deposit that’s progressing towards the pre-feasibility stage. Using material from Commerce Resources’ (TSXV:CCE) Ashram project in northern Quebec, l’Université Laval successfully used an alternative flowsheet approach to create a mixed REE concentrate. The tests add to the work of Hazen Research in Colorado and Merker Mineral Processing/UVR-FIA in Germany.

Commerce announced receipt of Laval’s final report on August 1. The university tested Ashram material on bench-scale levels of one kilogram and on larger batches of 10 to 30 kilograms. A total of about 1,500 kilograms went through Laval’s own flotation circuit and Reagent Scheme.

The large batches produced around 170 kilos of flotation concentrate grading 11.2% rare earth oxides, with a mass pull of 11.3% (percent of material reporting to concentrate), the company stated. Laval’s new reagent scheme offers Ashram potentially greater flotation performance, Commerce added.

“We are very happy with the results of our collaboration with Laval and look forward to continued work with local academic institutions to further develop REE expertise in the province of Quebec and, moreover, to move the Ashram deposit closer to production,” commented president Chris Grove.

The news comes amid heightened concern in the U.S. for critical minerals supply, especially rare earths.

Commerce holds interests in two other critical minerals projects. On the Niobium Claim Group, just a few kilometres from Ashram, Saville Resources TSXV:SRE drilled high-grade, near-surface niobium along with tantalum and phosphate last spring while working towards a 75% earn-in from Commerce. The latter company also holds the advanced-stage Blue River tantalum-niobium project in southern British Columbia.
