Golden Sky Minerals Corp. reported sampling and mapping results from the Mowich Target at its Rayfield-Gjoll property in southern British Columbia, identifying coherent copper-in-soil trends reaching up to 521 parts per million copper.

The spring 2026 program targeted the relationship between surface geochemistry, geology, and geophysical anomalies. The soil survey defined multiple elongated copper-in-soil trends concentrated through the central portion of the survey area, with anomalous values spatially associated with mapped diorite, monzodiorite, and monzonite intrusive rocks.

Rock sampling along the margin of a diorite returned up to 2,216.1 parts per million copper, or 0.22% copper, occurring in close spatial association with elevated copper-in-soil responses. The results highlight intrusive contacts and structural zones as potential controls on hydrothermal fluid flow and mineralization. Outcrops of picrite identified along the margins of the intrusions showed intense talc-carbonate alteration. Float material located downslope from these altered outcrops returned high grades in historical sampling, including 37.46% copper, 286 grams per tonne gold, and 200 grams per tonne silver.

Golden Sky expanded the project land position by approximately 7,288 hectares along its southwestern portion to cover interpreted prospective structures associated with historical copper-gold mineralization.

“At Mowich, the growing correlation between copper-in-soil anomalies, mapped intrusive rocks, alteration and structure is helping us build a stronger geological model and providing clear direction for the next stage of exploration. Our decision to expand the Rayfield-Gjoll land position by approximately 7,300 hectares reflects both geological and strategic considerations.”

The Rayfield-Gjoll property serves as the company's flagship copper-gold asset in British Columbia and is subject to an option and joint venture agreement with Boliden AB, under which Boliden can earn up to an 80% interest by funding up to C$20 million in exploration. Golden Sky also consolidated full ownership of ground within the project through an agreement with Strata GeoData Services.
