Executive Summary

• Maxus Mining Inc. has entered into a 2025 exploration partnership with Palliser Exploration Ltd. to execute field programs across four critical minerals projects in British Columbia: Quarry, Hurley, Lotto, and Alturas.
• Palliser Exploration will conduct on-site field evaluations to understand geological and structural controls on mineralization, with field teams mobilizing on September 23, 2025.
• The release provides detailed historical assay data and geological context for each property, highlighting high-grade antimony, gold, silver, copper, and tungsten potential, including recent high-grade antimony discoveries at the Alturas project.

Key Details

• Partnership Structure: Maxus Mining contracted Palliser Exploration Ltd., an experienced geologic and exploration consultancy, to execute the 2025 field program.
• Mobilization Date: Field teams are expected to mobilize on Tuesday, September 23, 2025.
• Quarry Project (Antimony/Gold/Copper/Lead/Silver):
  • Located on the north side of the Osilinka River, BC (2,632 hectares).
  • Hosts recrystallized and dolomitized limestones of the Neoproterozoic Ingenika Group.
  • Historical sampling (1991) returned: 20% Sb, 0.89 g/t Au, 3.8% Cu, 42.5% Pb, and 0.65 g/t Ag.
  • Earlier grab samples (1954) averaged 83.5% Pb and 1,575 g/t Ag.
• Hurley Project (Gold/Antimony/Silver):
  • Consists of Hurley East and Hurley West blocks, located 7 km southeast of Gold Bridge, BC.
  • Hurley East Block: Adjacent to Endurance Gold’s Reliance project, which reported 19.2% Sb and 2.16 g/t Au over 0.5 m in 2024. Recalculated composites show a weighted average grade of 4.55 g/t Au, 0.20% Sb, and 4.97 g/t AuEq.
  • Proximity to past producers: Mary Mac Main zone (78,500 tonnes at 2.9 g/t Au) and Gray Rock (70,488 tonnes at 3% Sb, 2.1% Pb, 342.8 g/t Ag).
  • Hurley West Block: Hosts narrow quartz-calcite veins with minor disseminated pyrite, chalcopyrite, and stibnite. Nearby Stibnite prospect averages 8.9% antimony.
• Lotto Project (Tungsten):
  • Located 19 km west-southwest of Castlegar, BC (426 hectares).
  • Contains the Lotto 3 showing with scheelite mineralization in a nine-metre-wide quartz vein.
  • 1980 grab sample assayed 10.97% WO3.
  • Geology includes Paleozoic argillaceous quartzites and Middle to late Jurassic Nelson intrusions.
• Alturas Project (Antimony/Gold/Silver):
  • Comprises Alturas West and Alturas East blocks, located ~29 km northeast of New Denver, BC.
  • Alturas West: Hosts a shear zone with quartz veining and disseminated pyrite/argentiferous tetrahedrite.
  • Recent discovery: Assays returned up to 69.98% Sb.
  • Historic adit sample assayed 1.3 g/t Au and 1,596 g/t Ag.
  • Alturas East: Situated near the Highland Surprise mine. Historic sampling revealed 6.56 oz/t Ag, 0.95% Cu, 3.90% Pb, and 9.32% Zn.
• Additional Portfolio Context:
  • Maxus holds ~14,989 hectares total, including the Penny copper project (3,123 hectares) near the Sullivan mine, which returned copper values up to 2,388 ppm Cu in 2017.
