Maxus Mining Engages Geotech Ltd. to Complete Winter 2026

Multi-Block Airborne Geophysical Survey in British Columbia

January 27, 2026

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

that it has engaged Geotech Ltd. (“Geotech”) to complete a large, multi-block airborne geophysical survey across its

Alturas, Hurley, Lotto, and Quarry Projects in British Columbia (the “Projects” or the “Properties”). Geotech is a

globally recognized airborne geophysical services provider, having celebrated its 45th year of operations in 2025. The

company is one of the largest privately owned airborne EM survey operators worldwide, with more than ten (10)

million line-kilometres of airborne geophysical surveys completed to date.

The proposed survey (the “Program”) will be comprised of approximately 1,417 line-kilometres flown over six survey

blocks and will utilize Geotech’s patented Versatile Time-Domain Electromagnetic (“VTEM™”) system. VTEM™ is a

helicopter-borne time-domain electromagnetic (“TDEM”) and magnetic system designed to provide the sensitivity,

resolution, and depth of investigation required to image subsurface geological features in structurally complex and

topographically challenging terrain.

The survey is designed to improve the Company’s understanding of potentially 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 300–500 metres. Results from the Program are expected to assist in refining

priority exploration targets and supporting future drill planning across the Projects.

The airborne TDEM and magnetic surveys are anticipated to commence in early 2026, subject to weather conditions,

and are expected to be completed prior to spring 2026. Maxus will receive daily data deliveries throughout the

Program. Convolutions Geoscience (“Convolutions”), led by Kyle Patterson, P.Geo., will provide ongoing quality

assurance and quality control (“QA/QC”) oversight during the survey to ensure data integrity and consistency. The

Company has engaged Convolutions to drive strategic geophysical targeting and interpretation, as disclosed in the

Company’s news release on December 16, 2025.

“This airborne geophysical program represents an important technical step in advancing our British Columbia project

portfolio,” said Scott Walters, Chief Executive Officer of Maxus. “High-quality geophysical data will allow our technical

team to better constrain subsurface structural architecture, prioritize targets, and support efficient planning for future

exploration activities across multiple Projects.”

Qualified Person Statement

The scientific and technical information contained in this news release has been reviewed, verified, and approved by

Morgan Verge, P.Geo., Technical Advisor of the Company and a “qualified person” as defined in NI 43-101 – Standards

of Disclosure for Mineral Projects. Ms. Verge has examined information regarding the historical exploration at the

Properties, 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 the Properties. 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 the Properties.

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)†. The project 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.
