(TSXV: AUEN) (\"Golden Sky\" or \"The Company\") is pleased to announce the results of its 735 line-kilometre helicopter-borne ZTEM (Z-Axis Tipper Electromagnetic) and aeromagnetic geophysical survey over the Gnome and Semlin Targets on the Rayfield Property. This survey represents Phase 1 of the Company's 2025 exploration program and was designed to refine geological understanding and guide targeting for Phase 2, which will focus on follow-up exploration on these two targets. The program successfully delineated a large, high-resistivity geophysical anomaly interpreted to represent an intrusive batholith that extends from the Semlin target to the Gnome target, providing strong geological continuity across the broader project area. This intrusive body is interpreted to play a key role in the metal fertility and hydrothermal alteration setting occurring throughout the region, and further supports the potential for a district-scale porphyry system.At the Gnome target zone, exploration has outlined a broad multi-element soil anomaly (Cu-Au-Zn-As-Mo) measuring approximately 1.8 km by 1.5 km, open to the southeast, highlighting strong potential for additional mineralized extensions. This geochemical footprint is indicative of a robust hydrothermal system and supports the presence of a buried porphyry target at depth, a target that has been further corroborated by results from the 2025 ZTEM geophysical survey. The Gnome area was historically explored as a molybdenum prospect, but has undergone only limited modern drilling, leaving much of the target underexplored (see Figures 1, 2, 3 and 4).Surface sampling has outlined polymetallic mineralization hosted in chalcedonic quartz-carbonate veins containing disseminated pyrite and chalcopyrite. One such vein returned notable grades of 0.35% Cu, 8.9 g/t Ag, and 4.8 g/t Au (historical sample), demonstrating the high-grade potential of near-surface mineralization. Widespread phyllic and propylitic alteration occurs across the target area. Of particular significance is the close spatial relationship between surface mineralization and a prominent, eastward...
