Guardian Exploration completes airborne geophysical survey at Mount Cameron

Calgary, Alberta--(Newsfile Corp. - July 16, 2026) - Guardian Exploration Inc. (TSXV: GX) (OTCQB: GXUSF) (FSE: R6B) ("Guardian" or the "Company") is pleased to announce the successful completion of a high-resolution airborne magnetic and radiometric survey over its 100%-owned Mount Cameron Project ( "Mount Cameron" or the "Project" ), an exploration-stage silver-lead-zinc project located in the Mayo Mining District of central Yukon, Canada. Highlights High-resolution airborne magnetic and radiometric survey completed across the Mount Cameron Project. Survey designed to identify structural features, alteration zones and geological contacts that may control high-grade silver-lead-zinc mineralization.

Final processed geophysical products will be integrated with existing geological, geochemical and LiDAR datasets. Processed geophysical interpretations will assist in prioritizing drill targets for the Company's ongoing exploration program. The survey was completed by Precision GeoSurveys Inc. ( "Precision" ) of Langley, British Columbia, using a helicopter-borne geophysical platform designed to acquire magnetic and radiometric data across the Project area.

The survey totalled approximately 669 line-kilometres over a 30.3 km² block, flown on 108°/288° survey lines at 50 m spacing (tie lines at 500 m) and a nominal flight height of 40 m above ground, using a cesium-vapour magnetometer and a 21-litre NaI(Tl) gamma-ray spectrometer. The survey is expected to enhance the Company's understanding of the geological setting, distribution of lithological units, and structural controls associated with mineralization at Mount Cameron. Graydon Kowal, President & Chief Executive Officer of Guardian Exploration, commented: "The completion of this airborne survey marks another significant step forward for Mount Cameron.

Modern airborne geophysics will provide an impo
