Great Atlantic Resources Plans Comprehensive 2026 Exploration Program at Elmtree Silver Mine & Keymet Silver Mine Incl. 2,500 Metres of Diamond Drilling - Northern New Brunswick

Executive Summary

• Great Atlantic Resources Corp. announced its 2026 exploration program for the 100% owned Keymet Precious‑Base Metal Project in northeast New Brunswick.
• The program will focus on the northwest region of the property, targeting extensions of known polymetallic vein systems and additional gold‑bearing zones, with up to 2,500 m of diamond drilling plus extensive geophysical, geochemical and trenching work.
• Historical production data and past high‑grade drill intercepts (e.g., 1,158 g/t Ag over 3 m) are highlighted to underscore the project's potential.

Key Details

• Property Overview: Two mineral claims (Nos. 4283 & 5643), ~3,340 ha, located ≈20 km NW of Bathurst, NB.
• Target Zones:
• Extension of polymetallic veins northwest of historic Keymet Silver Mine.
• Elmtree 12 vein system – strike and depth testing (target >150 m vertical).
• Additional veins near the historic Elmtree Silver Mine occurrence.
• Known gold‑bearing zones within the Elmtree 12 area.
• Planned Work for 2026:
• Prospecting, rock‑soil geochemical sampling.
• Induced‑polarization/resistivity and magnetic surveys.
• Multiple trenching campaigns.
• Up to 2,500 m of diamond drilling.
• Permitting: Permit applications for line‑cutting, excavator trenching and diamond drilling to be submitted to the New Brunswick government in February 2026.
• Historical Production (Keymet Silver Mine, mid‑1950s): ~59,000 t @ 33.9 g/t Ag, 2.59 % Zn, 2.44 % Pb, 0.25 % Cu; ceased 1956 after a surface fire.
• Notable Past Intercepts (Elmtree 12 system):
• Ky‑18‑14 – 3.00 m @ 1,158 g/t Ag, 9.04 % Zn, 9.19 % Cu, 2.16 % Pb.
• Ky‑17‑8 – 1.27 m @ 576 g/t Ag, 18.80 % Zn, 3.55 % Cu, 1.16 % Pb.
• Ky‑18‑10 – 1.00 m @ 223 g/t Ag, 16.80 % Zn, 1.60 % Cu.
• Additional intercepts ranging from 0.52 m to 4.95 m with high silver, zinc and copper grades.
• Historical High‑Grade Samples (Elmtree Silver Mine):
• 0.51 m core – 9.53 % Zn, 9.01 % Pb, 66 g/t Ag.
• Trench channel – 308 g/t Ag, 1.94 % Cu, 1.52 % Zn.
• Glacial float – 472 g/t Ag, 7.6 % Zn, 5.1 % Cu.
• Additional Silver‑Bearing Occurrences: Five historic occurrences (Elmtree 2, 6, 14; Keymet 3; Madran NE) with past assays up to 2 oz/ton Ag and significant base‑metal grades. Planned prospecting will target these zones in 2026.
• Qualified Person: David Martin, P.Geo., VP Exploration (NB & NL), NI 43‑101 qualified, approved the technical information.
