Maxus Mining Highlights Strong Polymetallic Results at the Alturas West Property in British Columbia, Canada

Executive Summary

• Maxus Mining released assay results from its 2025 reconnaissance program at the Alturas West property, highlighting strong polymetallic signatures with notably high antimony and silver grades.
• The most significant grab sample (G018729) returned 430 g/t Ag, 0.43 g/t Au, 1,410 ppm Sb, 0.34 % Zn, 0.35 % Cu and 0.16 % Pb, indicating a structurally‑controlled vein system.
• Results support targeting the central east‑west shear zone for the upcoming maiden drill program on Alturas West.

Key Details

• Program Overview – Conducted in Autumn 2025 by Palliser Exploration Ltd.; 15 grab samples assayed to evaluate historic targets across the property.
• High‑Grade Sample G018729 – Mine‑dump material with: 430 g/t Ag, 0.43 g/t Au, 1,410 ppm Sb, 0.34 % Zn, 0.35 % Cu, 0.16 % Pb.
• Second Notable Sample G018678 – Outcrop grab with: 87.7 g/t Ag, 0.15 g/t Au, 219 ppm Sb, 0.13 % Zn, 0.06 % Cu, 0.08 % Pb.
• Geochemical Interpretation – Data suggest a quartz‑dominant, structurally controlled hydrothermal vein system (Ag–Pb–Zn–Cu ± Sb) with limited dispersion and sharp geochemical contrasts.
• Target Prioritisation – East‑west 1.5 km shear zone identified as primary target for the forthcoming maiden drill program.
• Assay Methodology – Samples crushed, pulverised, digested (4‑acid), analyzed by ICP‑OES; Au measured by fire assay with gravimetric follow‑up if >10 g/t. QA/QC: certified reference material/blanks every 10 samples; two Maxus staff reviewed all certificates.
• Qualified Person – Morgan Verge, P.Geo., VP Exploration (NI 43‑101 qualified).
• Forward‑Looking Statements – Management indicates further exploration and drilling planned; no NI 43‑101 compliant resource estimate currently exists for the property.

Notable Quotes

“The 2025 field results at Alturas West continue to demonstrate the strength of the Project’s polymetallic system, with particularly encouraging enrichment in antimony alongside high‑grade silver,” – Scott Walters, CEO.

“These results confirm that antimony mineralization at Alturas West is not isolated, but part of a broader multi‑element system where silver represents an important value driver,” – Scott Walters, CEO.
