Maxus Mining Identifies Multiple Zones of High-Grade Mineralization from 2025 Surface Program at Alturas East

Executive Summary

• Maxus Mining completed its 2025 surface exploration program on the Alturas East Block, confirming polymetallic mineralization over a 500‑metre strike length with notable assays such as 18.2 g/t Au, 131 g/t Ag and 0.23 % Cu.
• Multiple target areas (SB 78, Olympus East/West, Gold Quartz Ridge) returned high‑grade grab samples for gold, silver, copper, lead, zinc, nickel and titanium, highlighting a robust multi‑commodity system.
• The results validate Maxus’s geological model and underscore significant upside potential for future drilling on the property.

Key Details

• Project Scope: 1,094 ha Alturas East Block in the Slocan Mining Division, BC; historic Alps‑Alturas Mine present; no systematic modern exploration since the 1970s.
• Program Contractor: Palliser Exploration Ltd. – completed detailed prospecting, mapping and surface sampling across the block in fall 2025.
• Overall Highlight Criteria Met: Au > 0.5 g/t, Cu > 5,000 ppm, Ag > 50 g/t, Zn > 5,000 ppm, Pb > 5,000 ppm, Ni > 2,000 ppm, Ti > 1 %.

Polymetallic Vein Corridor (Gold Quartz Ridge)

• Sample G018661: 18.2 g/t Au, 131 g/t Ag, 0.23 % Cu.
• Sample G018713: 13 g/t Au, 151 g/t Ag, 0.18 % Cu, 1.10 % Pb.
• Sample G018664: 1.96 g/t Au, 28.40 g/t Ag, 1.15 % Pb.
• Outcrop sample G018707: 9.79 g/t Au, 44.10 g/t Ag (in‑situ vein).

SB 78 Area

• Sample G018654: 1.53 % Cu, 4.90 g/t Ag (pentlandite‑bearing tuff).
• Sample G018703: 2.01 % Cu, 5.70 g/t Ag (metamorphosed intermediate‑mafic rock).

Olympus East

• Sample G018669: 9.40 g/t Ag, 0.26 % Pb, 0.99 % Zn (tetrahedrite vein).
• Additional float samples:
• G018668 – 363 g/t Ag, 3.40 % Pb, 1.05 % Zn, 290 ppm Sb.
• G018718 – 125 g/t Ag, 1.16 % Pb, 1.34 % Zn.
• G018719 – 40.60 g/t Ag, 0.10 % Pb, 1.41 % Zn.

Olympus West

• Sample G018671: 2,050 ppm Ni in pyroxenite outcrop.
• Sample G018672: 276 ppm Ni, 5.30 % Ti (serpentine‑altered pyroxenite).
• Sample G018721: 21.20 g/t Ag, 0.87 % Pb, 1.83 % Zn (tetrahedrite waste rock).

Additional Highlights

• Historic drillhole WBC‑80‑4 intersected 0.72 g/t Au over 0.91 m at 12.8 m depth (not followed up).
• All assays derived from grab samples; company cautions against reliance on individual values for grade continuity.

Sample Preparation & QA/QC

• Collected by Palliser crews, shipped to AGAT Laboratories (ISO‑9001:2015, ISO/IEC 17025 accredited).
• Methods: 4‑acid digest ICP‑OES; fire assay for Au; over‑limit protocols for >10,000 ppm metals.
• QA/QC: Certified reference material or blank every 10 samples; two Maxus staff reviewed certificates.

Qualified Person

• Morgan Verge, P.Geo., Technical Advisor (NI 43‑101 qualified) reviewed and approved technical content.

Notable Quotes

“What stands out in this Program is how consistently the assay results align with the district’s historic production profile… These outcomes validate our exploration model and highlight the potential for new discoveries along the same structural corridors.” – Scott Walters, CEO & Director, Maxus Mining Inc.
