Imperial Mining Develops High-Recovery Extraction Process for Scandium and Rare Earth Elements for Crater Lake Mineralization

MONTREAL, June 09, 2021 (GLOBE NEWSWIRE) — Imperial Mining Group Ltd. (“Imperial”) (TSX VENTURE: IPG) (OTCQB: IMPNF) is happy to announce that it has developed an progressive course of for extraction of scandium (Sc) and uncommon earth components (REE) from its Crater Lake scandium mineralization as a part of its present Section 3 Hydrometallurgical Improvement Program. Outcomes from this work present very excessive restoration of each scandium and uncommon earths for all mineralization sorts outlined in diamond drilling on the property.

The 2-stage hydrometallurgical extraction methodology entails a high-pressure caustic leach (HPC) adopted by hydrochloric acid leach of the HPC residue. The brand new methodology confirmed exceptional restoration of scandium and the uncommon earth components from Imperial’s Crater Lake Sc-REE mineralization (see Imperial Mining press launch dated March 2, 2020, for particulars of the MET samples herein talked about):

• The tactic confirmed scandium restoration to major leach answer (PLS) of 87% for MET01, and 84% for MET02 samples.
• The restoration of whole uncommon earth aspect, together with yttrium (TREE+Y) of 84%, from each MET01 and MET02 samples.
• The excessive recoveries of Sc and TREE+Y from each samples present that the strategy has glorious efficacy in extracting Sc and REE from samples representing completely different mineralization sorts noticed in drilling.

“We’re extraordinarily happy with the outcomes obtained up to now from our metallurgical take a look at work on Crater Lake mineralization,” mentioned Peter Cashin, Imperial’s President & CEO. “Together with our companions MPlan-Dorfner ANZAPLAN, we’ve got now obtained excessive scandium and uncommon earth recoveries from each the mineral focus and hydrometallurgical research phases of this system. Extra importantly, the method that we’ve got developed is efficient throughout the assorted mineralization sorts outlined on the mission to date. We at the moment are prepared to maneuver to the ultimate phases of our take a look at work to get well a high-purity scandium oxide product.”

Imperial Mining is at the moment working to additional optimize the method parameters with its hydrometallurgical growth companions, MPlan-Dorfner ANZAPLAN GmbH, and is planning to use for a patent for the brand new course of.

Imperial Mining Group and MPlan-Dorfner ANZAPLAN proceed to develop its hydrometallurgical flowsheet by treating a 100 kg mineral focus that was produced from two bulk samples collected from drillcore: MET01 and MET02. This system will get well scandium as scandium oxide (Sc₂O₃), and TREE+Y as a bulk focus. The Section 3 hydrometallurgical flowsheet growth program will likely be accomplished within the third quarter of 2021.
