On October 1, 2019, Imperial Mining Group Ltd. announced that they have engaged M.Plan International Limited to undertake Phase 2 metallurgical testwork on the Crater Lake Project scandium mineralization from the recently-discovered TG Zone.
“The metallurgical testwork is intended to optimize the already encouraging test results obtained from our Phase 1 work completed in 2018,” said Peter Cashin, Imperial’s President & Chief Executive Officer. “Based on the properties of pyroxene, olivine and amphibole, the target of the proposed testwork will be to reject the major portion of olivine, which contains no scandium, from the bulk mineral concentrate, thereby significantly improving scandium recovery and gangue mineral rejection. This is the first step toward defining a full process flowsheet including hydrometallurgical treatment of the mineral concentrate to recover marketable scandium oxide product for scandium-aluminum alloy applications.”
This work phase is expected to be completed sometime in the first quarter of 2020.
