Almadex Acquires Rattlesnake, Arizona Porphyry-Epithermal Project by Staking, Preliminary Surface Sampling returns 326 g/t Silver

Executive Summary

• Almadex Minerals acquired 100 % of the Rattlesnake early‑stage exploration project in Arizona by staking.
• Initial grab‑sample assay results are encouraging, with multiple samples showing >100 ppm Cu (up to 401 ppm) and one sample returning 326 g/t Ag and 1.52 % Zn.
• The company will conduct an aggressive soil‑sampling, IP geophysical program and additional mapping in winter 2025/26 to define drill targets.

Key Details

• Acquisition: 100 % interest in the Rattlesnake property obtained via staking; part of Almadex’s western U.S. regional exploration program.
• Geology: Quartz‑alunite and argillic hydrothermal alteration within andesite volcanic rocks, cross‑cut by altered dykes; stockwork quartz‑calcite veining with silver‑lead‑zinc mineralisation; elevated copper associated with quartz‑alunite ribs.
• Assay Results (39 of 96 grab samples):
• 7 samples > 100 ppm Cu, highest 401 ppm Cu, average 152 ppm Cu across all 39 samples.
• One vein sample: 326 g/t Ag and 1.52 % Zn.
• Remaining samples below detection or not significant.
• Planned Work (Winter 2025/26):
• Intensive soil‑sampling program.
• Induced Polarization (IP) geophysical surveys.
• Additional geological mapping and systematic sampling to delineate drill targets for preliminary testing.
• Management Comment: Chairman J. Duane Poliquin highlighted the identification of a large alteration zone interpreted as a porphyry lithocap and emphasized continued advancement of early‑stage projects and upcoming drilling on more advanced properties.
• Qualified Person: Morgan J. Poliquin, PhD, PEng (President & CEO) reviewed and approved technical content per NI 43‑101.
