Maxus Mining Announces Maiden Drill Program & Metallurgical Testing at the Alturas West Project in British Columbia, Canada
The Company will execute the first-ever drill program at the historic Alps-Alturas Antimony Mine, following up on over ninety-five (95) tonnes of historical production averaging 57.2% Sb1
VANCOUVER, British Columbia, May 07, 2026 (GLOBE NEWSWIRE) — Maxus Mining Inc. (“Maxus” or the “Company”) (CSE: MAXM | OTCQB: MXMGF | FRA: R7V) is pleased to outline its planned 2026 exploration program (the “Program”) at the Alturas West Project (“Alturas West” or the “Project”), located in British Columbia, Canada (Please see Figure 1).
The 2026 Program at Alturas West is designed to systematically advance high-priority targets through a combination of drilling, surface exploration, and early-stage metallurgical evaluation (Please see Figure 2). In parallel, the Company is undertaking a regional airborne geophysical program to support targeting across the Project.
“We are excited to advance Alturas West through a focused and disciplined exploration program in 2026,” commented Scott Walters, Chief Executive Officer of Maxus Mining. “With the addition of airborne geophysical surveys across our portfolio, we are strengthening our targeting pipeline and improving our ability to prioritize high-quality drill targets. At Alturas West, integrating geophysics with surface work, drilling, and early-stage metallurgical testing is a key step toward fast-tracking the Project toward development. By advancing metallurgical understanding early, we aim to accelerate the potential pathway to production and contribute to establishing a secure, domestic antimony supply for North America.”
2026 Exploration Program Highlights – Alturas West
- Up to two thousand (2,000) metres of diamond drilling is planned to test high-priority exploration targets and expand the known historical zones of antimony mineralization;
- Drill targets refined through the integration of newly acquired VTEM data, 2025 prospecting results, and 3D structural modeling;
- A comprehensive surface sampling Program is planned to refine geological models and generate additional drill targets; and
- Early-stage metallurgical testing, including ore-sorting studies, are planned to evaluate processing characteristics and potential cost optimization pathways.
Integration of VTEM Surveys to Enhance Targeting
Maxus has engaged Geotech Ltd. to complete a VTEM airborne electromagnetic survey across the Project.
At Alturas West, the Company plans to integrate VTEM results with historical datasets and recent fieldwork to refine drill targeting. The geophysical data is expected to improve the understanding of subsurface structures and conductive zones, supporting the identification and prioritization of high-quality drill targets ahead of the 2026 drill Program.

Focused Advancement at Alturas West
The planned drill program at Alturas West will target the depth and extensions of known mineralization zones identified through historical exploration and recent fieldwork completed by the Company. Drilling is expected to provide key insights into the continuity, geometry, and grade distribution of mineralized zones, supporting future resource development efforts.
In parallel, Maxus will undertake a large-scale sampling campaign across the Project to expand geochemical coverage and improve targeting. This work is expected to both refine existing targets and identify new zones of interest for follow-up exploration.
Metallurgical Evaluation and Ore-Sorting Potential
As part of its advancement strategy at Alturas West, Maxus plans to initiate early-stage metallurgical testing on selected material from surface and at depth from drill holes. This work will include ore-sorting studies to evaluate the potential for pre-concentration and early waste rejection.
Incorporating ore-sorting, recovery, mineralogy, and metallurgy studies into the early evaluation process aligns with the Company’s objective of identifying opportunities to enhance project economics through reduced processing costs, improved feed grades, and more efficient material handling.
Upcoming Catalysts
- Completion of VTEM surveys across all projects;
- Mobilization of Alturas West Project summer drill Program (up to two thousand (2,000) metres);
- Commencement of surface sampling program at Alturas West; and
- Initial metallurgical and ore-sorting test results.
Community Engagement
Maxus recognizes that meaningful engagement with First Nations within whose territories we operate is a critical component of responsible exploration. The Company is actively engaging with First Nations communities in advance of and throughout its 2026 exploration Program at Alturas West, including providing updates on planned drilling and field activities, discussing potential impacts and identifying opportunities to incorporate community input into project planning. Maxus is committed to maintaining transparent communication, minimizing environmental and social disturbance, and building long-term, respectful relationships as exploration progresses.

About Maxus Mining Inc.
Maxus Mining Inc. (CSE: MAXM | OTCQB: MXMGF | FRA: R7V) 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 totaling 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% Sb¶. The Hurley Antimony Project, located adjacent to Endurance Gold Corp.’s Reliance Gold Project, where 2024 drilling reported 19.2% Sb and 2.16 g/t Au over 0.5 m‖, and the Quarry Antimony Project, which hosts historical polymetallic samples grading 0.89 g/t Au, 3.8% Cu, 0.34% Zn, 42.5% Pb, 0.65 g/t Ag, and 20% Sb‡.
Maxus’ 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% 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 1046 ppm Cu (TK17-149c), 1808 ppm Cu (TK17-28), and 2388 ppm Cu (TK17-12)†. The Project is strategically located near the historic Sullivan Mine at Kimberley, British Columbia, an area that continues to attract significant exploration activity.
Maxus Mining is committed to advancing its British Columbia projects through targeted exploration programs designed to unlock value across multiple critical mineral systems.
