Crater Lake Scandium-Rare Earth Property in Northeastern Quebec - 2021

Mining & Minerals - Evaluations / Critical Mineral Resources

• Crater Lake mineralization is HIGHLY magnetic
• Magnetic separation is effective in reducing the mass of gangue minerals and recovery of payable metals
• 96% of scandium, and 74% of the total rare earths elements (TREE) recovered into 48%-63% mass of mineral concentrate for MET01 and MET02 samples
• A patentable hydromet method was developed under the program
• The hydromet method showed good recovery of Sc at 84%-87% for MET02 and MET01 respectively, and 84% TREE recovery for both samples
• TREE+Y will be recovered as a bulk rare earth concentrate suitable for tolling through a REE separation plant

• Zone dimensions: 300m X 200m in depth: Open in all directions
• Thickens and gets richer at depth
• Cut-off NSR: $CA110.80/t ; Ore value NSR: $CA386-413/t

Sufficient for a minimum 40-year operating model; double anticipated minimum NSR based on delivery of Sc2O3 and a bulk Magnet Rare Earth concentrate: additional byproduct credits possible
