MAXUS MINING EARNS 100% INTEREST IN THE ALTURAS WEST PROPERTY INCLUDING THE PAST PRODUCING ALPS-ALTURAS ANTIMONY MINE

Maxus Mining Inc. has earned a 100-per-cent legal and beneficial interest in the Alturas West property, part of the company's flagship Alturas antimony project, located in British Columbia's Slocan mining division.

The company has fulfilled all remaining obligations under its previously announced property option agreement with Eminence Minerals Ltd. (formerly Equinox Resources Ltd.), including the accelerated issuance of consideration shares, resulting in Maxus securing full ownership of the Alturas West property.

Alturas antimony project overview

The company's flagship Alturas antimony project comprises two claim blocks, Alturas West and Alturas East, and is situated on the historic high-grade Alps-Alturas antimony mine within the prolific Slocan mining district. The project hosts a 1,300-metre mineralized corridor characterized by quartz veins containing stibnite (Sb2S3) mineralization within a structurally controlled shear zone.

Historical production from the Alps-Alturas mine averaged approximately 57.2 per cent antimony, with reported grades reaching up to 59.5 per cent antimony (Sb). More recent sampling has returned ultrahigh-grade antimony values, further supporting the project's potential as a high-impact critical minerals asset.

Transaction highlights:

• 100-per-cent ownership achieved: All requirements under the option agreement have been satisfied, securing full legal and beneficial ownership of Alturas West.
• Flagship asset advancement: Alturas remains a cornerstone project within Maxus's growing portfolio of critical mineral assets.
• Strategic positioning: Full ownership provides the company with flexibility to advance exploration, permitting and development initiatives across the broader project.

Maxus is continuing to advance exploration planning across the project, including data integration, target refinement and progression toward drill-ready targets.

"We are very pleased to have completed the acquisition of a 100-per-cent interest in Alturas West, a key component of our flagship Alturas antimony project," commented Scott Walters, chief executive officer of Maxus Mining. "This milestone strengthens our position in the antimony sector and provides us with full control to advance exploration and development across the project. We appreciate the co-operation of Eminence throughout this process and look forward to unlocking further value at Alturas."

Next steps

With full ownership now established, the company will focus on:

• Advancing permitting and regulatory processes;
• Integrating geological, geochemical and geophysical data sets into a 3-D model;
• Refining high-priority targets across both Alturas West and East;
• Preparing for future exploration and drilling programs.

About Maxus Mining Inc.

Maxus Mining is a mineral exploration company focused on locating, acquiring and, if warranted, advancing economic mineral properties in premier jurisdictions. The company is actively progressing its diversified portfolio totalling approximately 15,098 hectares of prospective terrain across British Columbia, Canada.

The portfolio includes 8,920 hectares across three antimony projects, anchored by the flagship Alturas antimony project, where a recent discovery returned high-grade naturally occurring antimony up to 69.98 per cent Sb. The Hurley antimony project, located adjacent to Endurance Gold Corp.'s Reliance gold project, where 2024 drilling reported 19.2 per cent Sb and 2.16 grams per tonne (g/t) gold (Au) over 0.5 metre, and the Quarry antimony project, which hosts historical polymetallic samples grading 0.89 g/t Au, 3.8 per cent copper (Cu), 0.34 per cent zinc (Zn), 42.5 per cent lead (Pb), 0.65 g/t silver (Ag) and 20 per cent Sb.

Maxus's portfolio further includes the 3,054-hectare Lotto tungsten project, where a selected 1980 grab sample from a scheelite-bearing quartz vein assayed 10.97 per cent WO3, and the 3,123-hectare Penny copper project, which has over 100 years of recorded exploration. Recent work programs at Penny included rock sampling and geological mapping, with 2017 sampling returning copper values of 1,046 parts per million (ppm) Cu (TK17-149c), 1,808 ppm Cu (TK17-28) and 2,388 ppm Cu (TK17-12). The project is strategically located near the historic Sullivan mine at Kimberley, B.C., an area that continues to attract significant exploration activity.

Maxus Mining is committed to advancing its British Columbia projects through targeted exploration programs designed to unlock value across multiple critical mineral systems.
