Powermax Minerals commences airborne surveys at Pinard and Hopkins

Toronto, Ontario--(Newsfile Corp. - June 16, 2026) - Powermax Minerals Inc. (CSE: PMAX) (OTCQB: PWMXF) (FSE: T23) (the "Company" or "Powermax") is pleased to announce the commencement of high-resolution helicopter-borne geophysical surveys and field exploration programs at its Pinard and Hopkins rare earth element ("REE") properties, located in Ontario. The airborne surveys are being completed by Geo Data Solutions GDS Inc. ("GDS") and are designed to collect high-resolution magnetic, radiometric spectrometric and VLF-EM data over the Pinard and Hopkins properties. The surveys are intended to assist the Company in defining geological structures, lithological contacts, alteration patterns, radiometric anomalies and potential exploration targets prospective for REE mineralization.

At the Pinard REE Property, the planned airborne survey comprises approximately 1,319 line-kilometres, including approximately 1,145 line-kilometres of traverse lines and 174 line-kilometres of tie lines. The traverse lines are planned at a nominal spacing of 50 metres, with tie lines at approximately 350 metres spacing.

Traverse lines are planned at a nominal spacing of 50 metres, with tie lines at approximately 350 metres spacing.

The surveys will be flown using GPS navigation and a planned 3D drape flight surface, subject to terrain, weather and aviation safety requirements.

GDS will complete field quality-control monitoring during the surveys, including checks of flight-path positioning, aircraft altitude and speed, magnetic diurnal variations, radiometric system performance and VLF-EM signal quality. The airborne survey data has not yet been fully processed or interpreted, and no exploration targets have been confirmed from the current program at this time. Results from the airborne surveys and field programs will be integrated with available geological information to prioritize areas for follow-up exploration.

In conjunction with the airborne geophysical programs, Powermax has also commenced field prospecting, geological mapping and sampling work at both the Pinard and Hopkins properties. The field programs are designed to follow up prospective geological trends, assess areas of radiometric and magnetic interest, identify favourable host rocks and structures, conduct radiometric surveys using handheld scintillometer, and collect rock, soil and other samples where warranted. Results from the airborne surveys and field programs will be integrated to prioritize targets for follow-up exploration.

"The commencement of airborne geophysics and field exploration at Pinard and Hopkins represents an important step in advancing our Ontario REE portfolio," said Paul Gorman, Chief Executive Officer of Powermax Minerals Inc. "The combination of high-resolution magnetic, radiometric and VLF-EM data with prospecting, mapping and sampling will provide Powermax with a strong technical foundation to refine targets and guide the next phase of exploration." The Company expects to provide further updates as the airborne surveys and field programs progress and as data compilation, interpretation and analytical results become available.
