Neotech Metals Announces Distinct Apatite-Dominant Rare Earth Mineralization at Hecla-Kilmer

Executive Summary

• Independent SGS Lakefield study confirms that up to 98 % of total rare‑earth elements (TREO) at the Hecla‑Kilmer project are hosted in apatite, a mineralogy that enables low‑temperature, low‑acid leaching.
• Apatite in the deposit contains an average of 7.4 % TREO and accounts for ~82 % of the total rare‑earth distribution across sampled intervals.
• The study supports previously announced metallurgical test work and underpins the upcoming maiden resource estimate expected in 2026.

Key Details

• Host Mineral: Apatite is the primary carrier of REEs, comprising 28–56 % of the rock matrix and containing up to 98 % of TREO across the dataset.
• TREO Concentration: Composite apatite samples average 7.4 % TREO; eight representative samples from a 361‑m interval in drill hole HK22‑13 averaged ~1 % TREO at bedrock surface.
• Sample Statistics:
• 7 of 8 samples contain ≥85 % of total REEs hosted in apatite.
• 6 samples show >90 % of REE content within the apatite crystal structure.
• Discrete REE Minerals: Synchysite (0.36 %), monazite (0.05 %), bastnäsite (0.01 %) – together <1 % of mineral assemblage.
• Analytical Methods Used: TIMA‑X, EPMA, X‑ray diffraction (XRD), LA‑ICP‑MS.
• Metallurgical Implication: High apatite liberation (80–92 % across samples) at moderate grind sizes corroborates low‑temperature leachability demonstrated in April 2025 test work.
• Drilling Activity 2025: ~8,000 m of new drilling completed plus re‑logging/re‑assaying of ~1,900 m of legacy core (2020‑2023) for inclusion in the maiden resource estimate slated for 2026.
• Qualified Person: Jared Galenzoski, VP Exploration, P.Geo., reviewed and approved all technical data.

Notable Quotes

“Hecla‑Kilmer continues to distinguish itself from every comparable rare earth system we have studied,” said CEO Reagan Glazier. “The confirmation that rare earths are overwhelmingly hosted within apatite gives this project a unique foundation…we are very encouraged by the continued progress at the project as we advance and derisk a rare earth system that aligns with the goals of secure and sustainable value‑added supply chains needed for the green transition.”
