Deep Drilling Identifies Gold Bearing Structure at Tomingley

Executive Summary

• Alkane Resources reported multiple high‑grade underground intercepts at the Roswell deposit, including a 5.9 m interval grading 31.0 g/t Au (with 2.1 m @ 78.4 g/t Au).
• New seismic‑target drilling (RWD061) extended to 1,392 m depth intersected several gold‑arsenic enriched breccias, notably 8.7 m @ 1.15 g/t Au and a 0.3 m @ 11.4 g/t Au zone.
• Exploration at the El Paso prospect yielded a spectacular 0.5 m @ 77.5 g/t Au within a 17 m @ 4.02 g/t Au intercept, confirming continued mineralisation potential across the Tomingley project area.

Key Details

• Roswell Seismic Target (RWD061) – 8.7 m @ 1.15 g/t Au (incl. 3 m @ 2.78 g/t Au); 0.3 m @ 11.4 g/t Au; 2 m @ 5.90 g/t Au.
• Western Monzodiorite Underground Drilling – Highlights:
• ROSUG657D: 5.9 m @ 31.0 g/t Au (incl. 2.1 m @ 78.4 g/t Au).
• ROSUG644D: 17.4 m @ 4.30 g/t Au (incl. 2.5 m @ 21.1 g/t Au).
• ROSUG425D: 3.5 m @ 16.1 g/t Au (incl. 1.2 m @ 45.1 g/t Au).
• ROSUG656D: 0.6 m @ 69.2 g/t Au.
• El Paso Prospect – EPD020: 17 m @ 4.02 g/t Au (incl. 3.8 m @ 14.1 g/t Au and 0.5 m @ 77.5 g/t Au); additional 8 m @ 2.10 g/t Au.
• Westray Prospect – WSRC001: 1 m @ 2.49 g/t Au (115 m) and 6 m @ 0.59 g/t Au (143 m).
• Total underground drilling at Roswell: 21 holes, 4,019 m total length, grid spacing ~15 × 20 m, confirming multiple high‑grade zones within the Western Monzodiorite domain.
• Additional surface diamond drilling commenced to test extensions at Wyoming Three and northern Caloma; further underground work planned for Q3 2026 targeting upper/lower portions of the Inferred Roswell resource.
• Resource update: Roswell underground resources (1.3 g/t Au cut‑off) estimated 5.5 Mt @ 2.6 g/t Au = 476,000 oz Au (as at 30 Jun 2025).

Notable Quotes

“Our continuing exploration at Tomingley reveals both extensions to our deposits, which remain open at depth and along strike, as well as new areas of mineralisation. This drilling demonstrates the significant resource expansion potential across the mine site…” – Nic Earner, Managing Director & CEO, Alkane Resources Ltd.
