Just a Reminder: IPG will deliver PEA soon

Just for a reminder: 

The company is working with WSP Canada Inc. on a Preliminary Economic Assessment (PEA) to be delivered ''SOON'' as a NI 43-101 PEA-level technical report.

A combination of low intensity magnetic separation (LIMS) and wet high-intensity magnetic separation (WHIMS) produced a mineral concentrate yielding an impressive 88% Sc recovery as well 69% recovery of total rare earth elements (TREE) for one sample. A combination of LIMS and WHIMS on the second sample with differing mineralogy also yielded encouraging recoveries of 78% Sc and 56% TREE. Additional testwork utilizing Sensor-based ore sorting and heavy liquid separation (HLS) methods confirm that X-Ray Transmission (XRT) sensor-based sorting and dense media separation (DMS) offer additional low-cost alternatives for inexpensively producing a mineral concentrate without the need of grinding, chemical reagents or extensive water consumption. DMS separation yielded recoveries of 90.6% Sc and 89.2% TREE in the mineral concentrate.

Phase 3 of the Hydrometallurgical Development Program was conducted in 2021. Results from this work show very high recovery of both scandium and rare earths from samples representing different mineralization types defined in diamond drilling on the property. This innovative process is a two-stage hydrometallurgical extraction method that entails a high-pressure caustic leach (HPC) followed by hydrochloric acid leach of the HPC residue.

• The method showed scandium recovery to primary leach solution (PLS) of 87% for MET01, and 84% for MET02 samples.
• The recovery of total rare earth element, including yttrium (TREE+Y) of 84%, from both MET01 and MET02 samples.

Imperial Mining is currently working to further optimize the process parameters and develop its hydrometallurgical flowsheet as part of the Hydrometallurgical Development Program.
