Powermax Minerals Shares Combined Assay and Geophysical Findings for Atikokan Rare Earth Property in Northwestern Ontario

Executive Summary

• Powermax Minerals released 2025 rock, soil, and sediment assay results from the Atikokan REE Property, identifying multiple TREO anomalies up to 615.8 ppm and prioritizing targets in the Dashwa Gneiss Complex.
• Integrated geochemical‑geophysical interpretation highlights structurally controlled LREE mineralization associated with Th‑bearing minerals (monazite, allanite) and strong Th/U correlations.
• The company plans focused follow‑up exploration on high‑priority zones within Blocks B & C, while Block A is deemed lower priority.

Key Details

• Rock Sampling: 117 samples; TREO range 19.1–503.3 ppm; several >200 ppm; anomalies linked to gneissic units (Blocks B & C).
• Soil Sampling: 228 samples; TREO range 28.4–615.8 ppm; strong north‑south anomalies aligned with structural corridors and lithologic contacts.
• Sediment Sampling: 10 samples; TREO range 37.1–377.2 ppm; indicates downstream mechanical dispersion from proximal REE source rocks.
• Target Prioritization:
• Dashwa Gneiss Complex (Blocks B & C): Highest priority – REE enrichment tied to monazite and allanite, strong Th/U ratios, structural controls.
• White Otter Batholith (Block A): Lower priority – TREO 22–≈487 ppm typical of background granitic rocks; dispersed accessory minerals, weaker radiometric correlations.
• Exploration Model: Conceptual model suggests metamorphic/metasomatic LREE system concentrated along shear zones and fault intersections; REE‑Th‑U associations provide reliable vectors for drilling.
• Airborne Survey (Oct 2025): Magnetic & radiometric survey by Geo Data Solutions Inc.; 50 m line spacing, 25 m grid resolution, average flight altitude 44 m.
• Field Program: Comprehensive geological mapping, prospecting, radiometric surveys, and systematic sampling; total of 426 samples (including QA/QC) submitted to Agat Labs.
• Analytical Methods & QA/QC: Rock samples digested via sodium peroxide fusion, analyzed by ICP‑OES/MS; soil samples sieved to fine fraction; QA/QC included field duplicates, blanks, standards, and laboratory controls.
• Qualified Person: Afzaal Pirzada, P.Geo., Director of Powermax, reviewed and approved technical information under NI 43‑101.

Notable Quotes

“These results significantly advance our understanding of the Atikokan Property and clearly define a path forward for exploration… the strong association of rare earth elements with thorium and uranium geochemistry provides us with reliable vectors to prioritize targets.” – Paul Gorman, CEO
