Maxus Mining Initiates Airborne Geophysical Survey at its Alturas
Antimony Project in British Columbia
March 2, 2026
Vancouver, B.C. – Maxus Mining Inc. (“Maxus” or the “Company”) (CSE: MAXM | OTCQB: MXMGF | FRA: R7V) is
pleased to announce the commencement of an airborne geophysical survey at its flagship Alturas Antimony Project
(“Alturas”) in British Columbia. The Company has engaged Geotech Ltd. (“Geotech”), a globally recognized leader in
airborne electromagnetic surveying, to carry out a high-resolution Versatile Time-Domain Electromagnetic (“VTEM™”)
geophysical survey (the “Program”). This Program represents a key first step in advancing Alturas West toward drill
targeting and will also form part of a broader regional exploration initiative that extends to the Company’s Quarry,
Hurley, and Lotto properties (together with Alturas, the “Projects” or “Properties”).
“The commencement of this VTEM survey marks an important inflection point for Maxus across our Project portfolio,”
said Scott Walters, Chief Executive Officer of Maxus Mining. “This Program is designed to rapidly improve our
understanding of the subsurface architecture and structural controls that underpin antimony mineralization across
Alturas. With high-quality geophysical data in hand ahead of the 2026 field season, we will be well positioned to refine
priority drill targets and advance Alturas West in a disciplined, technically driven manner.”
The Alturas West portion of the survey will consist of approximately 149 line-kilometres spaced at one hundred (100)
metres and will significantly enhance the Company’s understanding of the property-scale structural architecture and
controls on mineralization at Alturas West. The Alturas East Project block survey will consist of approximately 177 line-
kilometres, spaced at one hundred (100) metres.
The Program has been specifically designed to identify geophysical signatures associated with shear -, sediment-
and/or intrusion-hosted mineral systems by mapping contrasts in bedrock resistivity and magnetic response. With
effective depth penetration in the range of approximately three hundred (300) to five hundred (500) metres, the
results are expected to provide critical subsurface insight and support the refinement of high-priority exploration and
drill targets ahead of the Company’s planned 2026 field program at Alturas West.
Geotech personnel have mobilized and survey operations have commenced, subject to weather conditions, and all
planned programs are expected to be completed prior to spring 2026. Maxus will receive daily data deliveries
throughout the Program. Convolutions Geoscience Corporation (“Convolutions”), led by Kyle Patterson, P.Geo., will
provide ongoing quality assurance and quality control (“QA/QC”) oversight to ensure data integrity and consistency.
Convolutions will also support strategic interpretation and targeting, as previously disclosed in the Company’s news
release dated December 16, 2025.
Qualified Person Statement
The scientific and technical information contained in this news release has been reviewed, verified, and approved by
Morgan Verge, P.Geo., VP Exploration of the Company and a “qualified person” as defined in NI 43-101 – Standards
of Disclosure for Mineral Projects (“NI 43-101”). Ms. Verge has examined information regarding the historical
exploration at Alturas, which includes a review of the historical sampling, analytical, and procedures underlying the
information and opinions contained herein.
Management cautions that historical results collected and reported by operators unrelated to Maxus have not been
verified nor confirmed by its Qualified Person; however, the historical results create a scientific basis for ongoing work
at Alturas. Management further cautions that historical results, discoveries and published resource estimates on
adjacent or nearby mineral properties, whether in stated current resource estimates or historical resource estimates,
are not necessarily indicative of the results that may be achieved on Alturas.

The “Historic Estimate” described above fall under the NI 43-101 definition of a “historic estimate” meaning that the
calculations were prepared prior to the February 1st, 2001, implementation of NI 43-101 and therefore do not conform
to NI 43-101 standards. No NI 43-101 compliant resource estimates exist to date on Alturas.
About Maxus Mining Inc.
Maxus Mining Inc. (CSE: MAXM | 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)†. Alturas is strategically located near the historic Sullivan Mine at Kimberley, British Columbia, an area that
continues to attract significant exploration activity.
Maxus is committed to advancing its British Columbia Projects through targeted exploration programs designed to
unlock value across multiple critical mineral systems.
