MAXUS MINING UNLOCKS VALUE AT SILVER-RICH QUARRY PROJECT WITH COMPLETION OF HISTORICAL DRILLHOLE COMPILATION & ANALYSIS OF HISTORICAL ESTIMATE

Maxus Mining Inc. has completed a comprehensive compilation of all available historical drill hole data for the company's Quarry project located in British Columbia, Canada. The company will begin detailed geological review and interpretation of this data set, which will be integrated with the coming VTEM airborne geophysical survey expected to be completed in the coming weeks. Together, these data sets will be instrumental in fast-tracking the project toward upgrading the historic Bull's-eye zone estimate to National Instrument 43-101-compliant mineral estimates.

Quarry project highlights:

• Historic drilling returned averages of:
  • 23.6 metres of 1.83 per cent lead, 2.82 per cent zinc and 56.2 grams per tonne silver in hole 77-111;
  • 13.0 m of 0.65 per cent Pb, 2.58 per cent Zn and 42.5 g/t Ag in hole 78-251;
  • 6.91 m of 2.42 per cent Pb, 2.43 per cent Zn and and 87.7 g/t Ag in hole 80-662;
  • 3.81 m of 1.00 per cent Pb, 3.19 per cent Zn and 43.5 g/t Ag in hole 80-762;
• Historic silver, lead and zinc estimates of the Bull's-eye zone (non-NI 43-101 compliant):
  • 99,781 tonnes of 1.42 per cent Pb, 2.24 per cent Zn and 36.3 g/t Ag (drill indicated);
  • 2.72 million tonnes of 3.66 per cent Pb plus Zn and 36.3 g/t Ag (original category not classified, three zones);
  • Historical block estimate, limits unknown;
• Cost-effective advancement: following the completion of historical data compilation, the company is actively interpreting and modelling subsurface geology and mineralization, aiming to quickly and effectively advance the project toward modern exploration and mineral-resource-focused drill programs;
• Strategic location: the project is situated 28 kilometres northwest of Germansen Landing, B.C., within favourable carbonate and dolomite breccia host rocks.

"The project hosts a compelling critical metals system with meaningful silver, lead and zinc mineralization demonstrated by historical drilling," said Morgan Verge, PGeo, vice-president of exploration at Maxus. "By compiling and validating the historic drill database and integrating it with our forthcoming airborne survey, we are positioning the project to rapidly refine targets and advance the Bull's-eye zone toward a modern NI 43-101-compliant resource."

Comments on reliability of historical estimate

The historical estimate for the property is sourced from property file PF40196, Suzie Mining Explorations Ltd. newsletter No. 17, prepared by Keith C. Fahrni, PEng, dated July 14, 1978. The estimate is historical in nature and does not include the limits or categories required under current Canadian Institute of Mining, Metallurgy and Petroleum definition standards. There are no directly comparable CIM categories that can be attributed to this estimate, and, to the knowledge of the qualified person, no modern mineral resource or reserve estimates exist for the property. A qualified person has not completed sufficient work to classify the historical estimate as current mineral resources or mineral reserves, and the company is not treating the historical estimate as current mineral resources or mineral reserves.

Work required to upgrade and verify the historical estimate includes a desktop compilation of historical drill data, confirmatory/twin drilling at appropriate spacing, specific-gravity testing by domain, modern analytical quality assurance/quality control with check assays, validation of collar locations and downhole surveys, development of a 3-D geological/grade model, and QP verification to CIM standards.

Quarry project historical summary

Historical work at the project has outlined multiple zones of base metal and precious metal mineralization. Historical grab sampling at the Regent mineral occurrence from a massive galena-bearing vein system returned average assays of 83.5 per cent Pb and 1,576 g/t Ag. Additional historical grab samples reported values including 20 per cent antimony, 42.5 per cent lead, 3.8 per cent copper, 0.89 gram per tonne gold and 0.34 per cent zinc, as well as 0.29 per cent Sb, 21.1 per cent Pb, 0.23 per cent Cu, 0.39 g/t Au, 583 g/t Ag and 0.57 per cent Zn.

Within the Bull's-eye zone, historic estimates reported 99,781 tonnes grading 1.42 per cent Pb, 2.24 per cent Zn and 36.3 g/t Ag (drill indicated), as well as 2.72 million tonnes grading 3.66 per cent Pb plus Zn and 36.3 g/t Ag (original category not classified, three zones).

As part of the company's initiative to complete a historic drill hole compilation across its entire property portfolio, these drill holes have been incorporated into the company's 2-D and 3-D workspaces and will be incorporated into a drill hole database in the coming weeks.

Qualified person statement

The scientific and technical information contained in this news release has been reviewed, verified and approved by Morgan Verge, PGeo, vice-president of exploration of the company, a qualified person as defined in National Instrument 43-101 (Standards of Disclosure for Mineral Projects). Ms. Verge has examined information regarding the historical exploration at the project, 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 continuing work at the project. 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 the project.

The historic estimate described above falls under the National Instrument 43-101 definition of a historic estimate meaning that the calculations were prepared prior to the Feb. 1, 2001, implementation of NI 43-101 and, therefore, does not conform to NI 43-101 standards. No NI 43-101-compliant resource estimates exist to date on the property.

About Maxus Mining Inc.

Maxus 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 g/t gold over 0.5 metre, and the Quarry antimony project, which hosts historical polymetallic samples grading 0.89 g/t Au, 3.8 per cent Cu, 0.34 per cent Zn, 42.5 per cent Pb, 0.65 g/t 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 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 is committed to advancing its B.C. projects through targeted exploration programs designed to unlock value across multiple critical mineral systems.
