About Crater Lake:

• Imperial's flagship project

• The only primary scandium project in North America located in mining-friendly Quebec.

• Robust PEA results issued in June 2022 (After tax NPV @10% of $1.72 billion, and IRR of 32.8%) (See PEA details here).

• See the update of October 25, 2023, for current initiatives.

• On September 14, 2023, Imperial reported the following key highlights based on the results of its NI 43-101 compliant Technical Report and Updated Mineral Ressources Estimate1 (available under Imperial's profile on SEDAR+):

  • Imperial's independent qualified persons from InnovExplo, report updated Indicated Resources of 11.8 million tonnes grading 275.9 g/t Sc2O3 and Inferred Resources of 15.9 million tonnes grading 268.4 g/t Sc2O3 for the Northern Lobe of the TG Scandium Zone.

  • The updated Mineral Resource Estimate represents a 58% increase in total scandium tonnage for the Indicated Resources category and a 22% increase in total scandium tonnage for the Inferred Resources category.

  • Determinations of magnet rare earth oxides (Nd, Pr, Dy, Tb) were made for both resource categories.

  • Using a Net Smelter Return (NSR) cut-off value of $CAN110.11/t for potential open pit extraction method, the value of the mineralization was determined to range between $CAN414-426/t.

  • Mineralization remains open laterally and at depth, demonstrating the potential to increase the mineral resource with additional drilling.
