Eagle Plains completes work at Hearne Hill South

Executive Summary

• Eagle Plains Resources completed a 32‑km soil geochemical survey and a 286‑km high‑resolution airborne magnetic survey at the newly assembled Hearne Hill South copper‑gold porphyry project in British Columbia.
• The work, executed by TerraLogic Exploration, identified geophysical anomalies consistent with intrusive geology and collected twelve rock grab samples, including a mineralized granodiorite sample showing chalcopyrite and malachite staining.
• Results and interpretation from the 2025 program are pending; the company will use the data to prioritize future drilling targets in the highly prospective Babine porphyry district.

Key Details

• Project Overview: Hearne Hill South covers 4,656 ha, is 100 % owned by Eagle Plains, road‑accessible, and situated ~70 km NE of Smithers, BC within the Stikine terrane of the Babine copper‑gold porphyry belt.
• Soil Geochemical Survey: >32 line km surveyed at ~50 m spacing on east/west‑oriented lines spaced 200–800 m apart; designed as a reconnaissance program to flag target areas.
• Rock Sampling: Twelve grab samples collected, including sample LWHHR001 (fine‑grained granodiorite with malachite staining, chalcopyrite mineralization, pervasive chlorite alteration, epidote veinlets, and specular hematite).
• Airborne Magnetic Survey: Completed Jan 2025; 286 line km at 100 m line spacing conducted by Precision GeoSurveys Inc. – high‑resolution data to delineate subsurface intrusive bodies.
• Data Status: Analytical results and geological interpretation for the 2025 work program are pending; Eagle Plains will release findings when available.
• Exploration Team: All field activities designed and executed by TerraLogic Exploration Inc., Cranbrook, BC.
• Geological Context: Property lies within Late‑Triassic (Takla Group) and Early‑Jurassic (Hazelton Group) volcanic sequences; prospective Eocene Babine igneous suite hosts known porphyry copper systems (e.g., Bell, Granisle).
• Regional Activity: Nearby projects include Amarc/Boliden’s Duke project ($10 M 2025 budget) and American Eagle Gold’s NAK project (30,000 m planned for 2025); South32 recently took a 19.9 % stake in American Eagle Gold.
• Cautionary Note: Rock grab samples are selective; historical results from adjacent properties are unverified and not necessarily indicative of Hearne Hill South potential.
