- The field exploration program generated a substantial geological, geochemical, and radiometric dataset across multiple target areas.
- Mapping identified granitic and pegmatitic units considered favorable hosts for rare earth element mineralization.
- Radiometric surveys returned elevated readings that warrant further investigation, with pending assay results from 426 samples expected to guide next exploration steps.
- The companies increasing progress aligns with rising investor focus on securing non-Chinese rare earth supply chains.
Powermax Minerals (CSE: PMAX) (OTCQB: PWMXF), a Canadian mineral exploration company, has completed its 2025 field exploration program at the Atikokan Rare Earth Elements property, marking a key technical milestone as the company advances its portfolio of REE-focused assets. The property is located in the Atikokan–Ignace–White Otter Lake district of northwestern Ontario, a region with established infrastructure and a history of mineral exploration.
Details of the completed program were outlined in a December 17, 2025, announcement which described a systematic exploration campaign designed to evaluate the geological and geochemical potential of the Atikokan property. The 2025 field program combined geological mapping, prospecting, ground-based radiometric surveys, and geochemical sampling across several priority target areas (https://ibn.fm/BaIsZ).
In total, 426 samples were collected, including quality assurance and quality control material. The sample set comprised 251 soil samples, 10 sediment samples, and 165 rock samples, providing broad coverage of both outcropping and overburden-covered areas.
Geological mapping identified three principal lithological domains across the property. Block A is dominated by granodiorite to granite, while Block B consists mainly of gneissic tonalite, with granodiorite and granite appearing in its northern portion. Block C is also largely gneissic tonalite, with granodiorite and granite becoming more prominent toward the north-northeast.
Granitic and pegmatitic rocks are commonly associated with late-stage magmatic processes, during which incompatible elements such as rare earths can become concentrated. By contrast, gneissic tonalite is generally viewed as less prospective unless it has been overprinted by later intrusions or fluid-driven alteration.
Powermax reported the presence of granitic and pegmatitic units across parts of the Atikokan property, which management considers a favorable geological indicator. While the company cautioned that there is no assurance of economic mineralization, the mapping results provide a framework for prioritizing future sampling and drill targets.
Radiometric surveying was another central component of the 2025 program. These surveys measure natural gamma radiation, reported in counts per second, which can reflect the presence of potassium, thorium, and uranium, elements that frequently occur alongside REEs in granitic and pegmatitic systems.
Background radiometric levels in gneissic tonalite typically ranged from 60 to 80 cps, considered low in a regional context. However, where pegmatite bands and pods were present within tonalite, readings increased to approximately 250 to 400 cps. Granitic and granodioritic units returned higher values overall, ranging from about 100 to as high as 2,700 cps, with the strongest responses recorded in pegmatitic zones.
From an exploration standpoint, readings above 200–300 cps are often viewed as anomalous in granitoid terrains, while values exceeding 500 cps generally justify closer follow-up. The elevated responses observed at Atikokan therefore support continued geological and geochemical evaluation.
The ground program complements a high-resolution helicopter-borne magnetic and radiometric survey that Powermax has already completed over the property. The company is awaiting final interpretation from the survey contractor, which will integrate airborne geophysical data with the 2025 field results. Management expects this integrated dataset to help refine structural controls, prioritize anomalies, and shape the next phase of exploration.
All samples collected during the program were transported under chain-of-custody procedures to AGAT Laboratories in Calgary, an ISO/IEC 17025-accredited facility, for multi-element geochemical analysis. Assay results have not yet been released and will be a near-term focus for investors assessing the project’s potential.
Chief Executive Officer Paul Gorman described the program as a foundational step for the Atikokan asset, noting that the scale and systematic approach have produced a robust technical dataset to support evaluation of both rare earth and critical metals potential.
The work at Atikokan takes place against a broader backdrop of rising strategic interest in rare earth elements. Global demand is projected to grow sharply, driven by electric vehicles, wind power, and defense applications. At the same time, supply chains remain heavily concentrated in China, which controls a majority of mining and processing capacity.
Powermax is positioning its portfolio to align with these trends. In addition to Atikokan, the company holds options on the Cameron REE Property in British Columbia and the Pinard REE Property in northern Ontario, and owns a 100% interest in the Ogden Bear Lodge Project in Wyoming.
