Copper Fox intersects high-grade soluble copper at the Van Dyke project in Arizona, with hole M-2 averaging 0.54% copper over 53.8 meters.

⑴Copper Fox has released the final assay results for its wholly owned Van Dyke in-situ copper recovery project’s 2026 historic core program in Arizona. Out of 18 newly reported drill holes, 15 exceeded the 0.025% total soluble copper cutoff grade used in the 2020 mineral resource estimate.⑵Drill hole M-2 returned a mineralized interval of 53.8 meters, with an average total copper grade of 0.54% and total soluble copper grade of 0.42%, including a high-grade sub-interval of 34.6 meters averaging 0.73% total copper.⑶Drill hole OXY-46 returned a mineralized interval of 74.6 meters, with an average total copper grade of 0.27% and total soluble copper grade of 0.22%, including an enriched zone of 19.5 meters averaging 0.52% total copper.⑷The expansion of the soluble copper envelope may impact the updated resource estimate, which is a key input currently being advanced for the revised preliminary economic assessment focused on engineering and cost studies.⑸Against the backdrop of global energy transition driving long-term bullish copper demand, the announcement of high-grade soluble copper intercepts enhances the project’s economic potential. In-situ recovery technology offers a lower environmental footprint and capital intensity compared to conventional mining, and further resource expansion would increase the project’s appeal to strategic investors or potential partners.
