Powermax Minerals Inc. (CSE: PMAX) (OTCQB: PWMXF) Refines Atikokan Rare Earth Targets as North America Seeks More Secure REE Supply

• The company has identified priority exploration zones at its Atikokan Rare Earth Property in northwestern Ontario following integrated geochemical and geophysical analysis.
• Soil, rock, and sediment sampling returned consistent rare earth element (“REE”) anomalies, supporting a structurally controlled mineralization model rather than isolated surface occurrences.
• The next exploration phase is expected to include additional field studies and potentially initial drilling campaigns to test whether anomalies translate into continuous mineralized zones.
• Rising global demand for REEs in electric vehicles, wind turbines, defense systems, and advanced electronics is increasing investor focus on domestic North American supply.
• China’s continued dominance in rare earth mining and processing has added strategic importance to early-stage Canadian projects such as Atikokan.

Powermax Minerals (CSE: PMAX) (OTCQB: PWMXF), a Canadian mineral exploration company focused on rare earth projects across North America, is narrowing its exploration focus at the Atikokan Rare Earth Property in northwestern Ontario, as the company moves from broad early-stage sampling toward more defined drill targets in a market increasingly focused on secure domestic supply of rare earth elements.

At Atikokan, the company combined results from rock, soil, and sediment sampling with airborne magnetic and radiometric surveys completed during 2025. The objective was to determine whether REE mineralization was broadly dispersed or concentrated along identifiable geological structures. The company said interpretation of geochemical assays and airborne geophysical surveys has helped identify structurally concentrated target zones where mineralization may be more likely to support future development (https://ibn.fm/vwz7s).

The Atikokan property consists of 455 unpatented mining claims and is one of the company’s more advanced projects in terms of integrated exploration work. Powermax also holds rare earth projects in British Columbia and Wyoming, including the Cameron REE property and the Ogden Bear Lodge Project.

Management said the results point toward a structurally controlled system. Two distinct geological environments were identified across the property. The Dashwa Gneiss Complex, covering Blocks B and C, has been prioritized for follow-up exploration, while the White Otter Batholith, known as Block A, has been assigned lower priority due to weaker geochemical relationships and more diffuse mineralization patterns.

The distinction is based largely on sampling results. Rock samples returned total rare earth oxide, or TREO, values ranging from 19.1 to 503.3 parts per million, with several results above 200 ppm. Soil samples showed values reaching 615.8 ppm, while sediment samples indicated downstream dispersion of REE-bearing material. These figures are typical of early-stage exploration systems, but the significance lies less in the headline values and more in how the anomalies cluster across the property.

According to the company, elevated REE values appear linked to structural corridors, shear zones, and lithological contacts; features that often act as pathways for mineralizing fluids. That supports a model where rare earth mineralization is concentrated along deformation zones rather than spread evenly across the project.

Geologists also identified geochemical associations between rare earth elements, thorium, and uranium, which are commonly used as pathfinder indicators in REE exploration. The presence of minerals such as monazite and allanite, both known hosts for light rare earth elements, adds support to that working model.

The 2025 technical program included airborne surveys flown at 50-metre line spacing, along with mapping, prospecting, and systematic sampling on the ground. A total of 426 samples were collected and analyzed by AGAT Laboratories using sodium peroxide fusion and ICP-OES/MS methods for near-total digestion of rare earth content. Quality control procedures included blanks, duplicates, and standards designed to improve reliability and consistency across the dataset.

The next phase of work is expected to focus on refining these targets through additional field studies and potentially initial drilling campaigns. The company noted that drilling will be necessary to determine whether the identified surface anomalies represent continuous mineralized zones with economic potential rather than isolated occurrences.

The findings come as the global demand for rare earth elements is anticipated to rise sharply over the next decade, driven by electric vehicles, wind turbines, military systems, and advanced electronics. Industry forecasts suggest global demand could triple from 59,000 tonnes in 2022 to 176,000 tonnes by 2035.

At the same time, supply remains highly concentrated. China controls roughly 60% of global rare earth mining and about 90% of processing capacity, giving it significant influence over pricing and supply chains. Export restrictions on certain critical minerals have added urgency to North American efforts to diversify supply.

Governments in both Canada and the United States have responded with policy support. In the U.S., mechanisms such as the Defense Production Act have been used to direct more than US$1 billion toward critical mineral development, while Canadian projects may benefit from cross-border funding eligibility and strategic partnerships.

That policy backdrop means early-stage exploration assets are increasingly being evaluated not only on geology, but also on their potential role in securing domestic supply chains. For Powermax, Atikokan sits directly within that discussion.

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.
