Vancouver, B.C. – Maxus Mining Inc. (“Maxus” or the “Company”) (CSE: MAXM | OTCQB: MXMGF FRA: R7V), is pleased to provide a summary of analytical results from the 2025 field program at its Lotto Tungsten Property (the “Project” or the “Property”), located in the Trail Creek 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 “Program”). The first round of results of the 2025 exploration and sampling program at the Project are summarized below (Please see Figure 1).
Lotto Tungsten Project Highlights
- Strategic Location: The Project is situated along Highway 3, approximately twenty (20) km west of Castlegar, British Columbia, providing excellent access to infrastructure and year-round exploration potential (Please see Figure 1).
- Cost-Effective Advancement: Integration of historical drilling and 2025 field results from the Program into a centralized 3D geological model is underway, supporting refined targeting and prioritization of prospective zones for follow-up work.
- Emerging Polymetallic System: Initial results indicate tungsten (“W”) and molybdenum (“Mo”) anomalism associated with quartz veining and alteration, reinforcing the potential for a structurally controlled polymetallic system warranting further systematic exploration.
Lotto Project Historical Highlights
- Historical ‘Loto 3’ showing consists of a 9-metre-wide quartz vein with scheelite (CaWO4) mineralization.1
- Disseminated scheelite present in quartz veins located northwest of the main Loto 3 showing and along the western edge of the highway.1
- Grab sample from the Loto 3 claim in 1980 from a quartz vein with scheelite returned high-grade* 10.97% WO3.1
*The Company considers results greater than 1.0 wt.% WO3 to be “high-grade”.
“The Lotto Property is beginning to demonstrate the characteristics we look for in a prospective critical minerals project,” said Scott Walters, Chief Executive Officer of Maxus. “These early results, combined with compelling historical data, are helping us define a clear path forward. Our next phase of work will focus on expanding the footprint of mineralization and advancing high-priority targets as we work to unlock the broader potential of this underexplored project.”

2025 Lotto 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 geological environments for potential mineralization at the Property and outlined several exploration targets across the Property (Please see Figure 1).1,2 Following the data compilation, the Company initiated the field reconnaissance Program to evaluate the generated target areas.
Two samples, G018634 and G018641, returned 105 ppm Mo and 21 ppm W, respectively (Please see Table 1; Figure 1). Both samples contained abundant quartz veining and strong iron-oxide alteration, hosted in altered siltstone and granodiorite, respectively.
Currently, the sample size and geochemical results are not robust enough to support a mineralogical interpretation. The Company is advancing plans for continued field programs focused on systematic rock sampling, detailed geologic mapping, and airborne geophysical surveys to strengthen the existing dataset and improve overall interpretive confidence. Expanding spatial coverage and increasing sample density would help capture lithological variability and structural complexity that may not be fully represented in the current data. Targeted sampling of underrepresented units and areas of structural interest would refine correlations and support more accurate geological models. Integrating consistent mapping methodologies with high-quality sample collection and documentation will ensure data reliability and comparability. The ongoing work will provide a more robust and comprehensive dataset, enabling better-informed analyses and supporting future exploration or research objectives.

**All sample values are from grab samples which by their nature, are not representative of overall metal grades of mineralized areas. Readers are cautioned to not place undue reliance on the assay values reported in the table above. The seven (7) samples above are part of a suite of sixty-seven (67) samples collected and assayed during the 2025 Lotto Prospecting Program.
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 were above upper detection limit, ran overlimit 4 Acid Digest, ICP-OES or ICP-Mass Spectrometry (MS)
- A Certified Reference Material or Blank was inserted at a frequency of 1 in 10 samples.
A minimum of two (2) Maxus personnel received all AGAT Laboratories assay certificates.
