Libra Energy samples 86 ppm Nb, 16 ppm Ta at Nemiscau

Executive Summary

• Libra Energy Materials Inc. released results from its 2025 maiden surface exploration program at its 100%-owned Nemiscau and Wegucci projects in Quebec's James Bay region.
• The six-day program collected 69 rock samples, identifying multiple pegmatite swarms with widths up to 30 metres and discovering a highly fractionated pegmatite at Wegucci.
• Geochemical sampling returned encouraging results, including up to 86 ppm Nb and 16 ppm Ta at Nemiscau, and 47 ppm Ga at both projects, covering less than 10% of the total combined area.

Key Details

• Program Scope: Six-day maiden surface exploration program; 69 rock samples collected across key target areas at Nemiscau and Wegucci projects.
• Geological Findings: Multiple pegmatite swarms identified; individual bodies reach estimated widths of up to 30 metres.
• Wegucci Specifics: Discovery of a notably more fractionated pegmatite than previously observed, designated as a priority target for follow-up work.
• Geochemical Results (Nemiscau): Values up to 86 ppm Niobium (Nb) and 16 ppm Tantalum (Ta) from pegmatites.
• Geochemical Results (Both Projects): Elevated Gallium (Ga) values recorded, peaking at 47 ppm in a pegmatite at Nemiscau.
• Coverage Status: The initial surface program covered less than 10% of the total combined area of both projects.
• Wegucci Property Details: Located in the Lac des Montagnes volcanic-sedimentary belt of the Opatica subprovince; covers 2,070 hectares; situated along the same structural corridor as Rio Tinto's Whabouchi lithium deposit.
• Nemiscau Property Details: Located in the Eastmain subprovince near James Bay, approximately 18 km south of Cygnus Metals' Pontax lithium deposit; covers 2,454 hectares; historically mapped as hosting rose-coloured pegmatitic granite; most ground remains underexplored.
• Qualified Person: Benjamin Kuzmich, PGeo, Vice-President, Exploration, reviewed and approved the technical information.

Notable Quotes

• "The program successfully identified multiple pegmatite swarms across both projects, with individual pegmatite bodies reaching estimated widths of up to 30 metres."
• "At Wegucci, field crews also discovered a pegmatite that is notably more fractionated than others observed to date, making it a priority target for potential follow-up work."
• "Importantly, this initial surface program covered less than 10 per cent of the total combined area of both projects."
