Maxus completes 2025 exploration program on Penny

Mr. Scott Walters reports MAXUS MINING COMPLETES 2025 EXPLORATION PROGRAM AT THE PENNY COPPER PROJECT Maxus Mining Inc. has completed the 2025 exploration program on its Penny copper project located in southeastern British Columbia, Canada. Resourceful Geoscience Solutions (RGS) and Expert Geophysics Ltd. were contracted to undertake the programs which were successfully executed through July and August, 2025, on time and under budget. Expert Geophysics completed a high-resolution airborne mobile magnetotellurics (MMT) survey across the entirety of the project. The survey was designed with 100-metre line spacing and 50 to 60 m height above ground, providing excellent resolution to delineate variationes in electrical resistivity across the project which could relate to occurrences of mineralization or hydrothermal alteration. Interim results are anticipated to be delivered within two weeks, and the company expects complete survey results within two months. Survey results will provide critical information for informing the next phases of exploration on the project. RGS undertook both field and desktop scopes of work on the project, including a detailed compilation of publicly available geographic and geoscientific data and review of past exploration methods and results. Over a two-week period beginning Aug. 7, RGS undertook a field program of soil sampling and prospecting. Soil sampling focused on expanding 2024 soil grids in strategic areas to further delineate statistically significant copper anomalies1. Prospecting activities were successful in identifying new occurrences of copper mineralization not previously documented. On the west block of the project, prospecting efforts focused on the historical Penny Man G mineral occurrence of sedimentary-hosted copper mineralization and in east project area across a southwest-northeast-trending structure intersecting the historical Penny Man H occurrence. New bedrock occurrences of copper mineralization were sampled in both regions. Scott Walters, chief executive officer of Maxus, commented: "The completion of our 2025 exploration program at the Penny Copper project marks a pivotal step in unlocking this high-potential asset in British Columbia. With expanded anomalies and high-resolution geophysical data, we're laying a foundation for targeted follow-up to delineate the deposit." Samples from the field program were delivered to Activation Laboratories (Actlabs) in Kamloops, B.C., for geochemical analysis. Soil and rock samples will undergo multielement analysis UT-1M with an aqua regia partial digestion and an inductive coupled plasma -- mass spectrometry (ICP-MS) finish. Gold content determinations will be made by method 1A2-ICP fire assay with an inductive coupled plasma -- optical emission spectrometry finish. Till samples were sent for a comparative multielement analysis with both partial aqua regia digestion as well as complete four-acid digestion and gold determinations by 1A2-ICP. Penny Man H showing From the British Columbia Mineral Occurrence database: "The Penny Man H showing area is underlain mainly by siltstone of the Middle Proterozoic Creston formation (Purcell supergroup) bisected by the northeast-trending Palmer Bar fault. Several areas of strata-bound and fracture-controlled copper mineralization were encountered along with quartz brecciation, bleaching and iron oxide fracturing. Several samples across the property were collected from veining with limonite and or base metals and chip sampling was completed locally. A 10-centimetre-wide fine-grained quartzite within green siltstone contains malachite on fractures. A sample (TK17-12) taken from the mineralized section graded 0.24 per cent copper." Penny Man G showing From the British Columbia Mineral Occurrence database: "The Penny Man G showing area is underlain mainly by siltstone of the Middle Proterozoic Creston formation (Purcell supergroup) bisected by the northeast-trending Palmer Bar fault. Several areas of strata-bound and fracture-controlled copper mineralization were encountered along with quartz brecciation, bleaching and iron oxide fracturing. Several samples across the property were collected from veining with limonite and or base metals and chip sampling was completed locally. In 2017, a one-metre-wide section of siltstone with disseminated bornite was noted, along molybdenite rosettes. A grab sample of this material, (sample TK17-28) graded 0.18 per cent copper, 6.7 grams per tonne silver and 19.1 parts per billion gold; molybdenum was negligible. Medium bedded fine-grained quartzite occurs to the immediate east of the siltstone layer." About the Penny copper project Previous exploration programs identified multiple zones of high-grade copper mineralization, with associated gold, barite and zinc values. These results highlight the strong mineral potential for the project and warrant further investigation. A newly discovered zone of buried outcrop returned assay results of up to 1,920 parts per million Cu (copper), 41 parts per billion Au (gold) and 1,310 ppm Ba (barium) over an approximate strike length of 50 metres. Multiple mineralized samples were collected from the Upper and Middle Creston formation sedimentary horizons. Interbedded and thin lenses of quartzite containing visible bornite, chalcopyrite and malachite returned copper values up to 1,046 ppm Cu (TK- 17-149c), 1,808 ppm Cu (TK17-28) and 2,388 ppm Cu (TK17-12). Qualified person statement The scientific and technical information contained in this news release has been reviewed, verified and approved by Sean Hillacre, PGeo, director of the company and a qualified person as defined in NI 43-101 -- Standards of Disclosure for Mineral Projects. 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 continuing work at the project. 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 project. About Maxus Mining Inc. Maxus Mining is a mineral exploration company focused on locating, acquiring and, if warranted, developing economic mineral properties in premier jurisdictions. The company is working toward progressing its diverse portfolio of exploration properties which includes approximately 14,355 hectares of prospective terrane comprising 8,178 hectares amongst three antimony projects, 3,123 hectares encompassing the Penny copper project and the remaining 3,054 hectares comprising the Lotto tungsten project. The Penny copper project covers approximately 3,123 hectares and has seen exploration activity throughout the last 100-plus years with recent work including rock sampling and minor geological mapping. The Penny copper project is located near the major past-producing Sullivan mine at Kimberley, B.C., an area that has stimulated both junior and major exploration company activities in the past year. Additionally, the Penny copper project saw a 2017 work program return 17 grab samples, which returned copper values up to 1,046 ppm Cu (TK17-149c), 1,808 ppm Cu (TK17-28) and 2,388 ppm Cu (TK17-12). At the Quarry antimony project, in well-established British Columbia, Canada, one historical sample taken assayed 0.89 g/t Au, 3.8 per cent Cu, 0.34 per cent Zn (zinc), 42.5 per cent Pb (lead) and 0.65 per cent g/t Ag (silver) and 20 per cent Sb (antimony). A selected grab sample taken in 1980 at the Lotto tungsten project from a quartz vein with scheelite assayed 10.97 per cent WO3 paragraph. Additionally, the Altura and Hurley antimony projects are strategically positioned; Altura is on strike from Equinox Resources recent antimony discovery which saw high-grade naturally occurring antimony with assays up to 69.98 per cent Sb; Hurley neighbours Endurance Gold Corp.'s Reliance gold project which saw antimony results from 2024 work programs include 19.2 per cent Sb and 2.16 g/t Au over 0.5 m encountered during the 2024 drilling program.
