[{"type":"text","content":" MONTREAL, July 28, 2020 (GLOBE NEWSWIRE) -- Imperial Mining Group Ltd. (\"Imperial\") (TSX VENTURE: IPG) is pleased to announce that it has engaged MPlan-Dorfner ANZAPLAN to carry out the Phase III metallurgical work program on the Crater Lake Project scandium mineralization. This program will focus on the development of an efficient hydrometallurgical process to recover a high-purity scandium oxide product from the scandium-rich mineral concentrates. “Given the positive results from the Phase II metallurgical test work, which showed improved scandium mineral recoveries, the next step is to develop an appropriate hydrometallurgical process flowsheet for these mineral concentrates,” said Peter Cashin, Imperial’s President & CEO. “To date, we have observed that the Crater Lake scandium mineralization can be concentrated by relatively simple, low-cost recovery techniques such as magnetic separation. An efficient hydrometallurgical process will allow us to produce a high-purity scandium oxide product to provide a low-cost, local source of scandium for Quebec’s aluminum industry.” PHASE III METALLURGICAL WORK PROGRAM Phase III metallurgical work will be performed on two mineralogically distinct bulk samples similar to those used for the Phase 2 development program (see Press Release: March 2, 2020) from which mineral concentrates will first be recovered. The Phase III program will then confirm, at the bench-scale, a hydrometallurgical process flowsheet for cost-effective extraction of scandium as 99.5% pure scandium oxide and recovery of a mixed rare earth oxide co-product. This involves dissolving the concentrates in an acidic solution to generate a pregnant leach solution (PLS) from which the contained scandium and the rare earths (“REE”) will then be extracted. In addition, the work program will look at the amenability of Crater Lake mineralization to acid soak/water leach or heap leaching techniques in solubilizing scandium and REE with the main objective of reducing reagent (acid) cost while optimizing payable metals recovery The program will commence upon delivery of MET01 and MET02 samples to Dorfner ANZAPLAN GmbH (Germany) laboratories in early August 2020. Estimated completion time from the date samples are delivered is four months, which brings program’s completion date to Q4 2020. In the Phase II program, a scandium m...
