Maxus Mining Inc. Continues to Return Strong Polymetallic Results At the Quarry Antimony Property in British Columbia
Maxus Mining Inc. provided a summary of analytical results from the 2025 field program at its Quarry Antimony Property (the “Project” or the “Property”), located in the Omineca Mining District in British Columbia. Maxus engaged Palliser Exploration Ltd. (“Palliser”) to complete a reconnaissance field program across the Project in autumn 2025. The second batch of sample results from the 2025 exploration and sampling program (the “Program”) at the Project is summarized below. Quarry Project 2025 Field Program Highlights: Strong Polymetallic Signatures: Recent results verify the polymetallic signature on the Project characterized in previous exploration programs, with several outcrop and grab samples returning significant anomalous values for silver (Ag), zinc (Zn), and lead (Pb) with associated antimony (Sb). Rock Sample Assay Highlights: 60.8 g/t Ag, 3.36% Zn, 4.09% Pb, in Sample G019851; and 23.7 g/t Ag, 10.5% Zn, 1.92% Pb, in Sample G019857. Previously Reported Rock Sample Assay Highlights: 234 g/t Ag, 110 ppm Sb, 0.46% Zn, 4.67% Pb, in Sample G019834;121 g/t Ag, 67 ppm Sb, 0.74% Zn, 2.35% Pb, in Sample G019827;52.1 g/t Ag, 68 ppm Sb, 9.62% Zn, 0.75% Pb, in Sample G019831;11.1 g/t Ag, 2.83% Zn, 0.36% Pb, in Sample G019828;10.5 g/t Ag, 4.39% Zn, 2.38% Pb, in Sample G019854;9.4 g/t Ag, 4.86% Zn, 0.597% Pb, in Sample G019833; and7.1 g/t Ag, 2.39% Zn, 0.26% Pb, in Sample G019853. Extension of Mineralization: 2025 grab samples extend the footprint of polymetallic mineralization in the northeast corner of the Project to over 350 metres in strike length. Strategic Location: The Project is located approximately twenty-eight (28) km northwest of Germansen Landing, British Columbia, with favourable carbonate and dolomite breccia host rocks that are prospective for polymetallic mineralization. Quarry Project Historical Highlights Historical samples from the 1990s assayed 0.89 g/t Au, 3.8% Cu, 0.34% Zn, 42.5% Pb, 0.65 g/t Ag, and 20% Sb. Historical grab samples from 1954 yielded assays averaging 83.5% Pb and 1,576 g/t Ag. Historic Silver, Lead, and Zinc Estimates of the Bullseye Zone (NI 43-101 non-compliant):99,781 tonnes @ 1.42% Pb, 2.24% Zn, 36.3 g/t Ag (drill-indicated);2.72 Mt @ 3.66% Pb + Zn, 36.3 g/t Ag (original category not classified, three zones);Historical block estimate, parameters unknown. 2025 Quarry Exploration Program: Combined assay results from the 2025 Program define two localized and well-developed polymetallic mineralization trends, dominated by silver, lead, and zinc as previously identified at the Property. Of the sixty-five (65) samples, nine (9) samples (comprising 12% of samples) exhibit pronounced multi-element enrichment that clearly stands out from the broader dataset. Table 1 presents selected assay results for samples collected during the Program. Two highlighted samples reported in this release, G019851 and G019857, were collected in the northeast corner of the Project and returned elevated lead and zinc values, up to 4.09% Pb and 10.5% Zn. These samples extend a NE–SW-trending zone of polymetallic mineralization over 350 m in length. The samples were taken from sandstone outcrop and subcrop along an exposed ridge. The samples displayed common quartz veining, silicification, and base metal mineralization. Overall, the geochemical results support interpretation of structurally controlled Ag–Pb–Zn ± Sb vein systems, with sharp geochemical contrasts indicating strong structural concentration of metals. These characteristics support the prioritization of detailed structural mapping and targeted sampling along known structural trends, specifically the E–W 450 m shear zone located in the southeast portion of the Property and the NE–SW mineralized trend in the northeast. Sample Preparation and Analytical ProceduresRock samples were collected by Palliser field crews with sample locations (in NAD83 UTM Zone 10 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 and 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 Digestion, Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) (201-070)Gold (Au) by fire assay (202-551)If Au >10g/t, run gravimetric 202-564If metals were above the upper detection limit, ran overlimit 4 Acid Digestion, 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.
