Commerce Resources to provide rare earths and byproduct samples to potential customers

 

With trade tensions once again demonstrating the need for rare earths supply outside China, Commerce Resources TSXV:CCE announced plans for its advanced-stage Ashram deposit in northern Quebec. The company intends to resume pilot plant metallurgical work, provide rare earths samples to interested parties and also upgrade its potential fluorspar byproduct.

Using lab facilities in Colorado, Commerce plans to produce several kilograms of material for companies that have requested samples. The lab will also work on upgrading the deposit’s fluorspar from metallurgical grade to the usually more expensive acid grade.

An essential ingredient for coolants used in refrigerators, freezers and air conditioners, acid grade fluorspar is also integral to processing uranium and aluminum. Like rare earths, fluorspar ranks among the 35 critical minerals listed by the United States. Over 60% of 2018 global production came from China, according to U.S. Geological Survey data. NorFalco Sales, a division of Glencore Canada Corp, has requested the fluorspar sample.

The pilot plant work will complement Commerce’s pre-feasibility studies as the Ashram deposit progresses.

Using Ashram material, the Colorado plant has already produced high-grade concentrates above 45% total rare earth oxides with recovery surpassing 70%, “comparable to current and past hard rock producers,” Commerce noted.

Separate, Quebec-funded studies at l’Université Laval produced a mixed rare earth oxide concentrate from Ashram material, showing the deposit’s versatility to processing procedures.

A key advantage of Ashram lies in its carbonatite-hosted mineralization and relatively simple monazite, bastnasite and xenotime mineralogy, amenable to conventional rare earths processing.

The near-surface deposit hosts a 2012 resource estimate using a 1.25% cutoff to show:

  • measured: 1.59 million tonnes averaging 1.77% total rare earth oxides

  • indicated: 27.67 million tonnes averaging 1.9% TREO

  • inferred: 219.8 million tonnes averaging 1.88% TREO

Ashram also features strong distribution of the high-demand magnet feed elements neodymium, praseodymium, dysprosium and terbium.

In a report issued last month, Adamas Intelligence stated that permanent magnets accounted for over 90% of TREO consumption by value last year. “This share is poised to expand further as demand (and prices) for neodymium, praseodymium, dysprosium and terbium continue to rise strongly in the years ahead.”

Ashram’s distinctions suggest the project could require a relatively smaller metallurgical plant, along with potentially lower capex and opex, Commerce stated.

Last May Commerce and two Inuit organizations signed a letter of intent to ensure participation as the project moves forward.

At another critical minerals project just a few kilometres away, Saville Resources TSXV:SRE works towards a 75% earn-in from Commerce on the Niobium Claim Group. Following a spring drill program that found high-grade, near-surface niobium along with tantalum and phosphate, Saville looks forward to a Phase II campaign.

In southern British Columbia, Commerce also holds the advanced-stage Blue River tantalum-niobium deposit.
