Boliden ABGolden Sky's Mowich copper-in-soil results and project expansion advance the Rayfield-Gjoll project that Boliden holds a C$20M earn-in/JV on

Golden Sky Minerals Corp. reported results from its spring 2026 soil sampling and geological mapping programs at the Mowich Target on its Rayfield-Gjoll Project in southern British Columbia, identifying strong copper-in-soil trends spatially associated with mapped diorite, monzodiorite and monzonite intrusive rocks. Copper-in-soil values rise from background levels of less than 50 ppm to greater than 300 ppm copper in several areas, with the highest assay reaching 521 ppm Cu, forming elongated and laterally continuous trends rather than isolated anomalies. Rock sampling along the margin of a diorite returned up to 2,216.1 ppm Cu, or 0.22% Cu, in close spatial association with elevated copper-in-soil response, supporting an emerging porphyry copper-gold exploration model. The company also expanded the project by approximately 7,288 hectares along its southwestern portion, covering interpreted prospective structures associated with historical copper-gold mineralization. President and CEO John Newell said the growing correlation between copper-in-soil anomalies, mapped intrusive rocks, alteration and structure is helping build a stronger geological model and providing clear direction for the next stage of exploration. The Rayfield-Gjoll Copper-Gold Project is subject to a C$20 million earn-in and joint venture with Boliden AB.
