VANCOUVER, British Columbia — March 2, 2026 — Leads & Copy —
Maxus Mining Inc. has commenced an airborne geophysical survey at its Alturas Antimony Project in British Columbia. The company has engaged Geotech Ltd. to conduct the high-resolution Versatile Time-Domain Electromagnetic (VTEM™) geophysical survey (the “Program”).
The program is a first step toward drill targeting at Alturas West and will extend to the company’s Quarry, Hurley, and Lotto properties. The properties, along with Alturas, are referred to as the “Projects” or “Properties”.
Scott Walters, Chief Executive Officer of Maxus Mining, said the VTEM survey marks an important inflection point for Maxus across its project portfolio. He added that the program is designed to improve the company’s understanding of the subsurface architecture and structural controls that underpin antimony mineralization across Alturas. The company expects that the high-quality geophysical data will allow it to refine priority drill targets and advance Alturas West.
The Alturas West portion of the survey will consist of approximately 149 line-kilometres spaced at 100 metres. The Alturas East Project block survey will consist of approximately 177 line-kilometres, spaced at 100 metres.
The program is designed to identify geophysical signatures associated with shear-, sediment- and/or intrusion-hosted mineral systems by mapping contrasts in bedrock resistivity and magnetic response. The company expects the results will provide subsurface insight and support the refinement of high-priority exploration and drill targets ahead of its planned 2026 field program at Alturas West. The effective depth penetration is expected to be in the range of 300 to 500 metres.
Geotech personnel have mobilized, and survey operations have commenced, subject to weather conditions. All planned programs are expected to be completed prior to spring 2026. Maxus will receive daily data deliveries throughout the Program.
Convolutions Geoscience Corporation, led by Kyle Patterson, will provide quality assurance and quality control oversight to ensure data integrity and consistency. Convolutions will also support strategic interpretation and targeting, as previously disclosed in the company’s news release dated December 16, 2025.
Maxus Mining Inc. is a mineral exploration company focused on locating, acquiring, and advancing economic mineral properties in premier jurisdictions. The Company is progressing its portfolio totaling approximately 15,098 hectares of terrain across British Columbia, Canada.
The portfolio includes 8,920 hectares across three antimony projects, anchored by the Alturas Antimony Project. The Hurley Antimony Project is located adjacent to Endurance Gold Corp.’s Reliance Gold Project, and the Quarry Antimony Project hosts historical polymetallic samples.
Maxus’ portfolio also includes the 3,054-hectare Lotto Tungsten Project and the 3,123-hectare Penny Copper Project. Alturas is located near the historic Sullivan Mine at Kimberley, British Columbia.
Maxus is committed to advancing its British Columbia Projects through targeted exploration programs.
Morgan Verge, P.Geo., VP Exploration of the Company and a “qualified person” as defined in NI 43-101 – Standards of Disclosure for Mineral Projects, has reviewed, verified, and approved the scientific and technical information contained in this news release. Ms. Verge has examined information regarding the historical exploration at Alturas, which includes a review of the historical sampling, analytical, and procedures underlying the information and opinions contained herein.
Management cautions that historical results collected and reported by operators unrelated to Maxus have not been verified nor confirmed by its Qualified Person; however, the historical results create a scientific basis for ongoing work at Alturas. Management further cautions that historical results, discoveries and published resource estimates on adjacent or nearby mineral properties, whether in stated current resource estimates or historical resource estimates, are not necessarily indicative of the results that may be achieved on Alturas.
The “Historic Estimate” described above fall under the NI 43-101 definition of a “historic estimate” meaning that the calculations were prepared prior to the February 1st, 2001, implementation of NI 43-101 and therefore do not conform to NI 43-101 standards. No NI 43-101 compliant resource estimates exist to date on Alturas.
