• The company has completed its 2026 field exploration program at the Cameron Rare Earth Element Project in British Columbia.
• The campaign generated 250 samples, comprising 50 rock-chip, 50 soil and 150 stream-sediment samples, all submitted to AGAT Laboratories for analysis.
• Assay results will help determine whether previously identified REE anomalies and geological observations warrant additional exploration.
• Cameron is part of a broader Powermax portfolio spanning Ontario and Wyoming, giving the company exposure to multiple North American REE districts.
• The company has also advanced exploration at Atikokan, Pinard, and Hopkins, broadening its pipeline of exploration targets during 2026.
• Powermax’s exploration activity comes as rare-earth supply chains remain geographically concentrated and governments in North America pursue greater domestic access to critical minerals.

Powermax Minerals (CSE: PMAX) (OTCQB: PWMXF), a Canadian mineral exploration company, has completed its 2026 field exploration campaign at the Cameron Rare Earth Element Project in British Columbia, shifting attention from fieldwork to laboratory analysis as the company works to establish whether previously identified rare-earth anomalies merit further exploration.

The July-August program covered priority areas across the approximately 2,984-hectare project and produced 250 samples. The dataset includes 50 rock-chip samples, 50 soil samples and 150 stream-sediment samples. Powermax has submitted the samples to AGAT Laboratories in Calgary, with results expected after laboratory analysis and the company’s quality-control and quality-assurance procedures.

The assays will provide quantitative information that can be compared with earlier geochemical results and geological observations, potentially helping Powermax refine targets for subsequent work.

Cameron had already produced evidence that justified the expanded field program. Earlier 2026 work reported Total Rare Earth Oxide values in soil samples ranging from approximately 135 parts per million to 2,840 ppm, with an average of about 340 ppm TREO. Several samples exceeded 400 ppm. The latest campaign was designed to broaden that dataset and improve the geological interpretation of the property.

Field teams encountered gneissic and granodioritic rocks, quartzite, pegmatitic material and quartz-veined or contact-zone material. Quartz, feldspar, biotite and muscovite were among the minerals observed, while localized oxidation and iron staining were also recorded. Those observations are useful for geological mapping, but they are not equivalent to laboratory assays. Similarly, handheld radiometric measurements collected at selected locations serve as field-screening tools rather than direct measurements of REE concentrations.

Cameron’s exploration is one part of a broader portfolio strategy. Powermax currently identifies four principal REE projects: Atikokan and Pinard in Ontario, Cameron in British Columbia and Ogden Bear Lodge in Wyoming. The company holds options to acquire the Canadian properties and owns a 100% interest in Ogden Bear Lodge.

Atikokan represents the largest Canadian land position in the portfolio. The project covers approximately 9,416 hectares in northwestern Ontario. Earlier airborne magnetic and radiometric surveys identified multiple exploration targets associated with geological structures, granitic and pegmatitic rocks and radiometric anomalies.

Powermax has continued expanding its exploration pipeline in Ontario. In June, the company commenced airborne geophysical surveys and field programs at the Pinard and Hopkins properties, using magnetic, radiometric spectrometric and VLF-EM data to help identify geological structures and potential REE targets.

The company also owns the 184-hectare Ogden Bear Lodge property in Crook County, Wyoming. The 22-claim property sits within the Bear Lodge district and shares a border with Rare Element Resources’ Bear Lodge Critical Rare Earth Project. Powermax describes its property as prospective for neodymium-praseodymium oxide mineralization, although mineralization on neighboring properties does not establish the presence or grade of mineralization on Powermax’s ground.

The geographic spread gives Powermax exposure to two major North American mining jurisdictions while allowing exploration results from individual properties to inform the broader portfolio. It also places the company within a market increasingly shaped by supply-chain considerations.

Rare earth elements used in permanent magnets are particularly important to electric motors, wind turbines and other advanced technologies. McKinsey estimates that demand for magnetic REEs could rise from 59,000 tonnes in 2022 to 176,000 tonnes by 2035. Its analysis also found that the currently announced project pipeline could leave a potential shortfall of roughly 60,000 tonnes by 2035, although market outcomes will depend on new mine development, processing capacity, substitution and recycling.

Supply concentration remains another consideration. McKinsey reported that China accounted for more than 60% of mined REE supply and more than 80% of refined supply in 2023. Recent export restrictions on certain medium and heavy rare earths have added to efforts by other countries to develop more resilient supply chains.

Exploration Target Cautionary Statement

The exploration targets discussed are conceptual, and there is currently not enough data to confirm a mineral resource. Further exploration may not yield successful results.
