Update: Quebec government, universities contribute to pre-feas studies for Commerce Resources’ Ashram rare earths project

by Greg Klein | Updated June 5, 2018

With financial support from the Quebec government and academic expertise from two universities, Commerce Resources TSXV:CCE announced progress on the pre-feasibility studies underway for the Ashram rare earths deposit.

On June 5 the company reported positive results from advanced tailings optimization tests conducted by le Centre Eau Terre Environnement of l’Institut national de la recherche scientifique, a branch of l’Université du Québec. Now in the second year of a three-year project, the work gets funding from les Fonds de recherche du Québec—Nature et technologies and le ministère de l’Énergie et des Ressources naturelles. The lab work found no serious concerns, no acid generating potential and “strong indications of no metal-leaching potential,” Commerce stated.

The positive outcome benefited from “the inherent low-sulphide and non-acidic nature of the carbonatite host rock,” said company president Chris Grove.

The program also looked at the mineralogy of an Ashram fluorspar concentrate, a potential byproduct of the deposit. Initial findings brought “very encouraging” signs that recovery of monazite grains could upgrade the purity of the fluorspar concentrate and potentially increase the overall recovery of rare earth elements into the primary rare earth concentrate, Commerce added.

The news follows a May 31 annnouncement that l’Université Laval will conduct pilot plant metallurgical tests on Ashram material in a program backed by a $365,000 grant from le ministère de l’Économie, de la Science et de l’Innovation.

Focusing on hydrometallurgical extraction of REEs and the use of new software to simulate their separation, the project will further develop Quebec expertise in REE separation and assess the economics of performing that work in the province. Results would help develop an alternative source of rare earths for global markets.

The work takes place as heightened awareness of critical minerals comes from an American strategy to reduce reliance on potentially unstable or unfriendly countries.

Both the hydromet process and simulator software have been tested in bench scale studies. Results brought recoveries surpassing 85% and showed positive correlation with the computer-simulated data. The current project further develops these studies at the pilot plant level.

With approximately two tonnes of Ashram material to work on, the project takes place at the SGS lab in Quebec City. The goal is to produce a high-grade concentrate, then a solution for partial separation into light, medium and heavy rare earth elements.

Beneficiaries of the project will be Quebec R&D and industry, as well as Commerce’s Ashram deposit as it progresses towards pre-feasibility. Previous government support for Ashram came from Ressources Québec, which invested $1 million in the company’s February 2017 private placement.

Looking at other critical minerals in safe jurisdictions, Commerce also holds the advanced-stage Blue River tantalum-niobium project in British Columbia, as well as an early-stage high-grade niobium prospect, conditionally subject to an earn-in by Saville Resources TSXV:SRE, on the Eldor property that hosts Ashram.
