Powermax Minerals Completes Phase 1 Exploration Program at Cameron Rare Earth Project

Vancouver, British Columbia--(Newsfile Corp. - June 3, 2025) - Powermax Minerals Inc. (CSE: PMAX) ("Powermax" or the "Company") is pleased to announce the completion of its phase 1 exploration work program (the "Program") at its Cameron rare earth elements (REE) property (the "Property") located in the Kamloops Mining Division, British Columbia, Canada. The Program was designed based on recommendations outlined in the Company's NI 43-101 Technical Report and comprised prospecting, geological mapping, soil and rock sampling and geophysical surveys.

Highlights of the program included:

• follow-up prospecting, mapping, and sampling in zones of elevated radioactivity and REE concentrations previously identified in historical and 2023 exploration;
• collection of a total of 105 grab and chip rock samples and 13 sediment samples;
• expansion of geophysical grid surveys to define the extent of previously identified exploration targets;
• systematic sampling of parallel radiometric anomalies and high-radioactivity zones delineated in 2023 airborne surveys, particularly in the eastern and western regions of the Property;
• representative sampling of all dominant rock types to help determine geological controls on REE mineralization, with scintillometer readings taken at each site;
• collection of sediment samples from tributaries and bars along Cranberry Creek, where historical reports suggested the presence of radiometric anomalies, to assess potential for placer-style REE mineralization; and
• recognition of Monashee Group lithologies favorable for REE mineralization, hosting granitic and pegmatitic intrusions and high-grade metamorphic rocks; and
• the samples have been submitted to the lab and the results are expected in 6-8 weeks time.

CEO Comment:

"We are very encouraged by the successful completion of Phase 1 at the Cameron REE Project," stated Michael Malana, Director and CEO of Powermax Minerals. "Our systematic approach has expanded our understanding of the geological framework and confirmed several priority areas for follow-up. The presence of Monashee Group rocks, with their known potential for rare earth mineralization, positions us well for future discovery. We look forward to receiving assay results and planning the next phase of exploration."

Quality Control and Quality Assurance (QA/QC)

Rock samples, including field duplicates, were collected in 0.3-2.0 kg quantities and securely sealed in plastic sample bags with sample numbers clearly marked. All samples were geo-referenced using handheld GPS units (UTM NAD 83, Zone 11N) and detailed with lithological and physical descriptors. Spot radioactivity readings were taken throughout the field program. Sediment and silt samples were collected from the B-horizon, bagged in kraft paper, and double-sealed for transport.

All samples were delivered to ALS Metallurgy in Kamloops for preparation. Prepared samples will be sent to ALS Geochemistry in North Vancouver for four-acid super trace multi-element analyses, including REE add-ons (ME-MS61L and MS61L-REE). ALS Laboratories is ISO 17025 accredited and is independent of Powermax.
