Maxus Mining Initiates Airborne Geophysical Survey at its Alturas Antimony Project in British Columbia

Executive Summary

• Maxus Mining has commenced a high‑resolution VTEM airborne electromagnetic survey over its flagship Alturas Antimony Project, covering ~149 km of line‑kilometres on the West block and ~177 km on the East block.
• The survey, conducted by Geotech Ltd. with QA/QC oversight from Convolutions Geoscience Corp., is intended to map subsurface resistivity and magnetic contrasts to refine drill target selection ahead of the 2026 field season.
• Data acquisition will be completed before spring 2026, providing daily data deliveries that will support strategic interpretation and targeting for upcoming drilling programs across Alturas and adjacent properties (Quarry, Hurley, Lotto).

Key Details

• Survey Contractor: Geotech Ltd., specialist in airborne electromagnetic surveying.
• Methodology: Versatile Time‑Domain Electromagnetic (VTEM™) system; line spacing of 100 m; effective depth penetration ~300–500 m.
• Coverage – Alturas West: Approximately 149 line‑km.
• Coverage – Alturas East: Approximately 177 line‑km.
• Purpose: Identify geophysical signatures associated with shear, sedimentary, and intrusion‑hosted mineral systems; improve understanding of structural controls on antimony mineralization.
• Data Delivery: Daily data deliveries to Maxus throughout the program.
• QA/QC Oversight: Convolutions Geoscience Corp., led by Kyle Patterson, P.Geo., providing quality assurance/quality control and strategic interpretation support.
• Timeline: Survey operations have commenced (subject to weather) with completion expected prior to spring 2026.
• Forward‑Looking Impact: Results are expected to enable refined high‑priority drill target selection for the 2026 field program at Alturas West, enhancing the technical basis for future exploration and potential resource development.
