Apex Discovers Mineralized Carbonatite at its Lac Le Moyne Project, Quebec

Executive Summary

• Apex Critical Metals announced the discovery of a new carbonatite occurrence at its 100% owned Lac Le Moyne project in Nunavik, Québec.
• Surface sampling returned multiple high‑grade niobium and rare‑earth oxide (REO) results, including boulder grabs >0.20 % Nb₂O₅ (max 0.40 %) and REO up to 0.50 %.
• An additional 77 mineral claims (~3,609 ha) were staked to cover the interpreted up‑ice source of the anomalous samples, expanding the target corridor for the 2026 field season.

Key Details

• Sampling Program: July 2025 helicopter‑supported operation; 151 rock samples collected – first targeted carbonatite exploration at Lac Le Moyne.
• Niobium Results: 4 boulder grab samples >0.20 % Nb₂O₅, highest assay 0.40 % Nb₂O₅.
• Rare‑Earth Oxide Results: 13 samples >0.25 % REO, peak value 0.50 % REO.
• Phosphate & Fluorine: 7 samples >5.0 % P₂O₅ (max 10.36 % P₂O₅); one sample assayed 4.94 % F.
• Geological Interpretation: Multi‑phase intrusive system with carbonatite and alteration‑related REE enrichment; north‑south‑oriented corridor identified as the most prospective zone.
• Land Expansion: Additional 77 claims (≈3,609 ha) staked on eastern margin to cover geophysical anomalies and up‑ice target area, now encompassing the primary corridor for follow‑up work.
• Quality Assurance/Control: Four certified reference materials and two quartz blanks inserted; analysis performed by Actlabs using XRF, ICP‑MS, fire assay, and fluorine-specific methods.
• Qualified Person: François Gagnon, P.Geo., Dahrouge Geological Consulting Ltd. (OGQ License 1907) reviewed and approved technical content.

Notable Quotes

“There are only ~600 known carbonatite systems globally… confirming the presence of carbonatite with substantially anomalous niobium and rare‑earth oxide mineralization… is a significant step forward for the Project.” – Sean Charland, CEO

Materiality Assessment: Non‑Material – Positive (early‑stage discovery that enhances project potential but does not yet constitute a resource or revenue‑generating event).
