PMET Resources Files NI 43-101 Technical Report on the CV5 Lithium-Only Feasibility Study on its Shaakichiuwaanaan Project

Executive Summary

• PMET Resources filed a NI 43‑101 technical report on SEDAR+, detailing the CV5 lithium‑only feasibility study for its Shaakichiuwaanaan Project.
• The report confirms a maiden Probable Mineral Reserve of 84.3 Mt at 1.26% Li₂O and a Consolidated Mineral Resource of 108.0 Mt at 1.40% Li₂O (Indicated) plus additional inferred resources, positioning the project as one of the largest lithium pegmatite deposits in the Americas.
• No material changes to assumptions or parameters from the original October 20 2025 feasibility announcement have occurred; the positive outlook and production target (~800 ktpa spodumene concentrate) remain unchanged.
