Maxus Mining Highlights Strong Polymetallic Results at the Alturas

West Property in British Columbia, Canada

February 11, 2026

Vancouver, B.C. – Maxus Mining Inc. (“Maxus” or the “Company”) (CSE: MAXM | FRA: R7V), is pleased to provide

highlights from its 2025 field program at the Company’s Alturas West Property (the “Project” or the “Property”),

located in the Slocan Mining District in British Columbia (Please see Figure 1). Maxus engaged Palliser Exploration Ltd.

(“Palliser”) to complete a reconnaissance field program across the Project in Autumn 2025. The first round of results

of the 2025 exploration and sampling program (the “Program”) at the Project are summarized below (Please see Figure

1).

Alturas West Project 2025 Field Program Highlights

• Strong Polymetallic Signatures: The Program highlights the polymetallic signature on the Project

characterized by previous exploration programs, with several outcrop and grab samples returning

significant values for silver (Ag), zinc (Zn), and lead (Pb)1 in addition to antimony (Sb).

• Rock Sample Assay Highlights:

o 430 g/t Ag, 0.43 g/t Au, 1,410 ppm Sb, 0.34% Zn, 0.35% Cu, 0.16% Pb in Sample G018729

o 87.7 g/t Ag, 0.15g/t Au, 219 ppm Sb, 0.13% Zn, 0.06% Cu, 0.08% Pb in Sample G018678

• Strategic Location: Located in the prolific Slocan Mining District, the Project boasts ideal access and

proximity to historic mining infrastructure, enabling efficient advancement of ongoing exploration

activities.

“The 2025 field results at Alturas West continue to demonstrate the strength of the Project’s polymetallic system,

with particularly encouraging enrichment in antimony alongside high -grade silver,” said Scott Walters, Chief

Executive Officer of Maxus. “The presence of antimony in association with elevated silver, copper, lead, and zinc

supports our interpretation of a focused, structurally controlled mineralizing system and reinforces the relevance of

Alturas West within our growing antimony portfolio.”

“These results confirm that antimony mineralization at Alturas West is not isolated, but part of a broader multi-

element system where silver represents an important value driver,” continued Walters, “As we integrate these

findings with historic data and ongoing structural interpretation, we believe the Project offers clear upside potential

and meaningful follow-up opportunities as we advance our exploration strategy in the Slocan Mining District.”

2025 Alturas West Exploration Program

Prior to mobilization, Maxus’ technical team reviewed historic assessment reports covering the Property and

compiled the results into a central GIS database. This work highlighted favourable geology and targets for potential

mineralization at Alturas West and outlined several exploration targets across the Property (Please see Figure 1).1,2

Following the desktop compilation, the Company initiated a field reconnaissance program to evaluate the generated

target areas.

Assay results from the Alturas West area define a highly localized but well-developed polymetallic mineralization

signature, dominated by silver, copper, lead, zinc, and antimony as previously identified at the Property.1,2,3 Most

samples return background to weakly anomalous values; however, two samples (G018678 and G018729) exhibit

pronounced multi-element enrichment that clearly stands out from the broader dataset. Table 1 below contains a

list of all samples collected during the Program.

The most anomalous sample, G018729, from a mineralized mine dump sample, returned elevated Ag (430 g/t), Cu

(0.35%), Pb (0.16%), Zn (0.34%), and Sb (1,410 ppm) (Please see Table 1 and Figure 2). This geochemical association,

combined with very low Ti, V, Sr, and Th, is consistent with quartz-dominant, structurally controlled hydrothermal

mineralization, likely representing oxidized polymetallic vein material or mine dump derived from such veins. The

strong enrichment in antimony is particularly significant and suggests focused fluid flow along discrete structures,

potentially reflecting a higher-temperature or more proximal position within the mineralizing system.

Sample G018678 defines a lower grade but compositionally similar polymetallic signature, indicating that high-grade

mineralization is not isolated to a single occurrence (Please see Figure 1 and Table 1). Surrounding samples with

moderate Pb-Zn-Sb enrichment are interpreted as representing halo or peripheral expressions of the same system,

potentially related to fracture-controlled leakage or diluted vein material.

Overall, the geochemical results support interpretation of a structurally controlled Ag–Pb–Zn–Cu ± Sb vein system,

with sharp geochemical contrasts indicating limited dispersion and strong structural localization. These

characteristics suggest that future exploration should prioritize detailed structural mapping and targeted sampling

along known structural trends specifically the east-west 1.5 km shear zone located in the center of the Property

(Please see Figures 1 and 2). These zones will be the priority target areas of focus for the maiden drill program on

the Project.

**All sample values are from grab samples which by their nature, are not representative of overall gold grades of

mineralized areas. Readers are cautioned to not place undue reliance on the assay values reported in the table

above. The fifteen (15) samples above are part of a suite of samples collected and assayed during the Program.

True thicknesses/widths of the mineralization is currently unknown to the Company at this time.

Sample Preparation and Analytical Procedures

Rock samples were collected by Palliser field crews with sample locations (in NAD83 UTM Zone 11 coordinates),

descriptions, visual characteristics, and photographs recorded in the field. Each sample was assigned a unique sample

ID and placed into a labelled sample bag along with a corresponding sample tag. Samples were stored securely during

the Program and transported directly by Palliser personnel to AGAT Laboratories in Calgary, Alberta for sample

preparation and geochemical analysis. AGAT Laboratories is accredited to ISO 9001:2015 ISO/IEC 17025 for specific

analytical methods.

The following sample preparation, analysis, and quality assurance and quality control methods were performed:

- Dry <5kg, Crush to 75% passing 2mm, split to 250g (method code 200-075)

- Pulverize to 85% passing 75 microns (method code 200-087)

- Metals by 4 Acid Digest, Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) (201-070)

- Gold (Au) by fire assay (202-551)

- If Au >10g/t, run gravimetric 202-564

- If Metals >10,000ppm, ran overlimit 4 Acid Digest, ICP-OES or ICP-Mass Spectrometry (MS)

- A Certified Reference Material or Blank was inserted at a frequency of one (1) in ten (10) samples.

A minimum of two (2) Maxus personnel received all AGAT Laboratories assay certificates.
