Dakota Gold Expansion Drilling Intersects High-Grade Gold Mineralization at Richmond Hill

Core Viewpoint - Dakota Gold Corp. has reported significant expansion drilling results from the Richmond Hill Oxide Heap Leach Gold Project, indicating widespread gold mineralization and potential resource growth, with drilling results confirming mineralization extending 230 meters north of the current resource boundary [1][3]. Drilling Campaign Overview - The company has completed 242 drill holes in its 2025 drilling campaign, totaling 29,279 meters (approximately 96,000 feet), with 136 assay results released so far and 106 pending [2]. - The drilling campaign is designed for metallurgical sampling, condemnation drilling, infill drilling, and expansion drilling, aimed at refining resource models and improving geo-metallurgical domain precision [4]. Highlights from Drill Results - Significant high-grade gold mineralization has been confirmed in the northern project area, with results to be incorporated into an updated resource model and ongoing feasibility study [3]. - Notable drill results include: - RH25C-303: 4.52 grams per tonne (g/t) over 15.2 meters, including 31.90 g/t over 1.8 meters [7]. - RH25C-261: 2.87 g/t over 17.3 meters [7]. - The northeast mineralization remains open and has been drill-tested up to 300 meters north and 535 meters wide [7]. Future Plans - Drilling will pause for the remainder of December 2025 and resume in mid-January 2026, with remaining assay results expected to be shared in early 2026 [3]. - The company aims to advance the Richmond Hill project to commercial production by 2029, alongside outlining a high-grade underground gold resource at the Maitland Gold Project [9].
