Powermax Identifies Multiple High-Priority REE Exploration Targets at Atikokan Property Following Helicopter-Borne Geophysical Survey Data Interpretation and Other Updates

Toronto, Ontario--(Newsfile Corp. - January 12, 2026) - Powermax Minerals Inc. (CSE: PMAX) ("Powermax" or the "Company") is pleased to announce interpretation results of a high-resolution helicopter-borne magnetic and radiometric survey completed over its Atikokan Rare Earth Element (REE) Property in northwestern Ontario. The survey results have identified multiple structurally controlled REE exploration targets across Blocks A, B, and C of the property, providing a strong technical foundation for integration with follow-up fieldwork data.

Key Highlights

• Multiple structurally controlled REE exploration targets have been identified, characterized by favorable granitic and pegmatite host rocks and associated magnetic lows.

• Elevated Th/K radiometric ratios, acting as effective total rare earth element (TREE) proxies, highlight REE-fertile alteration zones, while strong spatial correlations between radiometric patterns, structural trends, and lake-sediment TREE anomalies further validate these targets.

• Collectively, the geophysical and geochemical signatures support a phosphate-rich NYF-type REE system enriched in REE, Thorium, Uranium, and Yttrium.

Target Areas by Block

• Block A: Northwest- and north-trending structural corridors crosscut the granitic phases of the White Otter Batholith, coinciding with magnetic lows, elevated Th/K ratios, and anomalous lake-sediment REE values. These features collectively define priority targets along altered intrusive margins.

• Blocks B and C: Northeast-trending structures crosscut the gneissic tonalite and granodioritic units of the Dashwa Gneiss Complex, with radiometric anomalies aligning to mapped granitic and pegmatitic intrusions. These relationships define favourable metasomatic alteration zones developed along high-strain corridors and intrusive contacts.
