Vancouver, B.C. – Maxus Mining Inc. (“Maxus” or the “Company”) (CSE: MAXM | FRA: R7V), is pleased to provide a summary of exploration highlights on the western block of its flagship Alturas Antimony Project (Please see Figure 1). The Alturas West Block (“Alturas West” or the “Project”) is comprised of 899 hectares of prime critical mineral exploration ground in the Slocan Mining Division in British Columbia (Please see Figure 2)1. The Project hosts the past-producing Alps-Alturas Mine. The Company has completed a comprehensive review of all available historic assessment reports on the Project outlining several historic critical mineral occurrences and prospective antimony exploration potential at Alturas West.
Key Highlights:
- High–Grade Antimony Mineralization: historicalgrab samples confirmed high-grade Antimony (Sb) grades including samples ALT24-PS-R003, ALT24-JL-R004, and ALT24-JL-R005 returning 69.98% Sb, 67.96% Sb, and 49.98% Sb respectively.2
- Historical Production: approximately 95 tons of high-grade antimony-bearing material was shipped from the historic Alps-Alturas Mine site averaging 57.2% Sb, including 24.5 tonnes of material grading 50-60% Sb.3
- Prime Jurisdiction & Location: Alturas West is road accessible, strategically located in the historically significant Slocan Mining Division, north of the significant past-producing Silvana Mine.1
Scott Walters, Chief Executive Officer of the Company, commented, “The identification of a 1.7-kilometre antimony trend through historic sampling marks an important milestone for our team. This discovery positions the Project as a compelling opportunity within Canada’s growing critical minerals landscape, and we look forward to advancing exploration to define the full scope of this mineralized system.”

About the Alturas West Block
The Company recently expanded Alturas West by 239[A1] % through a strategic acquisition from Equinox Resources. As a result of this expansion, the Company added the past-producing Alps-Alturas Mine (Please see Figure 2).
The historical Alps-Alturas Mine saw approximately 95 tonnes of cumulative production at an average grade of 57.2% Sb.2 South of the Alps-Alturas Mine, the Project covers more than two kilometres of a significant east-west trending reactivated shear zone hosting disseminated pyrite and argentiferous tetrahedrite, with minor stibnite and chalcopyrite[A2] (Please see Figure 2).2 Prior to the Company’s expansion of Alturas West, Equinox Resources recently discovered massive stibnite in quartz veins along this largely un-tested structural trend, returning high-grade antimony values in rock chip samples up to 69.98%.2
A 4-kilogram sample of dumped material from a historic adit on the Project assayed 1.3 ppm Au and 1,596 ppm Ag in the Dolly Varden Prospect area (Please see Figure 2).4 The Dolly Varden Prospect warrants follow-up exploration due to its description in the 1928 Minister of Mines Annual Report as a 1.2m quartz vein hosting disseminated to massive stibnite within (or associated with) serpentinite ultramafic rock locally altered to listwanite (quartz-carbonate-mariposite).5
Historic surface rock chip sampling in 1990 on the Project outlined outstanding antimony potential over 1.7 km along the major shear zone on the Project in addition to potential across strike up to 700m. Two rock samples along the main structure were mineralized with stibnite (Sb2S3), and assayed over 1,000ppm Sb (Please see Figure 2).6
Anomalous gold values are positively correlated with higher arsenic values, indicating arsenic could be used as a pathfinder mineral along trend. Geochemical assay results also reveal an association between silver, copper, and antimony, possibly due to tetrahedrite ((Cu,Fe,Zn,Ag)12Sb4S13) mineralization.6 Figure[A3] [A4] 2 illustrates the locations of significant historical results and key geological features. Table 1 contains a summary of the significant results.

The Company is working towards progressing its diverse portfolio of exploration properties which now includes approximately 15,342 hectares of prospective terrane comprising 9,165 hectares amongst three antimony projects, 3,123 hectares encompassing the Penny Copper Project & the remaining 3,054 hectares comprising the Lotto Tungsten Project.
The Penny Copper Project covers approximately 3,123 hectares and has seen exploration activity throughout the last 100+ years with recent work including rock sampling and minor geological mapping†. The Penny Copper Project is located near the major past producing Sullivan Mine at Kimberley, British Columbia, an area that has stimulated both junior and major exploration company activities in the past year. Additionally, the Penny Copper Project saw a 2017 work program return 17 grab samples, which returned copper values up to 1,046 ppm Cu (TK17-149c), 1,808 ppm Cu (TK17-28) and 2,388 ppm Cu (TK17-12)†.
At the Quarry Antimony Project, in well-established British Columbia, Canada, one historical sample taken assayed 0.89 ppm Au, 3.8% Cu, 0.34% Zn, 42.5% Pb, and 0.65% ppm Ag and 20% Sb‡. A selected grab sample taken in 1980 at the Lotto Tungsten Project from a quartz vein with scheelite assayed 10.97% WO3§. Additionally, the Alturas and Hurley Antimony projects are strategically positioned; Alturas Project had a recent antimony discovery which saw high-grade naturally occurring antimony with assays up to 69.98% Sb¶; Hurley neighbours Endurance Gold Corp.’s Reliance Gold Project which saw antimony results from 2024 work programs include 19.2% Sb and 2.16 ppm Au over 0.5 m encountered during the 2024 drilling program‖.
