[{"type":"text","content":" Lead, South Dakota--(Newsfile Corp. - December 23, 2025) - Dakota Gold Corp. (NYSE American: DC) (\"Dakota Gold\" or the \"Company\") is pleased to report additional drill hole assay results from the Richmond Hill Oxide Heap Leach Gold Project (\"Richmond Hill\" or the \"Project\") including expansion drilling that has intersected gold mineralization as far as 230 meters (755 feet) north of the current Measured and Indicated resource boundary. Drill results continue to confirm widespread gold mineralization and resource growth potential. The Company has safely and successfully completed 242 drill holes in its 2025 drilling campaign totaling 29,279 meters (~96,000 feet). To date, a total of 136 drill hole assay results including the results today have been released from the campaign thus far. Assays for 106 drill holes are pending release, including many from northeast expansion drilling, which will be reported as they are received through early 2026. Highlights from this update include: Expansion and infill drill holes RH25C-303 intersected 4.52 grams per tonne gold (g/t Au) over 15.2 meters (69 gram meters), including 31.90 g/t Au over 1.8 meters (57 gram meters), RH25C-307 intersected 1.43 g/t Au over 30.2 meters (43 gram meters) and RH25C-313 intersected 1.74 g/t Au over 25.7 meters (45 gram meters). The first two drill holes listed were located 50 meters (165 ft) and 100 meters (330 ft) north respectively of the current Measured and Indicated resource boundary. The mineralization in the northeast is only limited by drilling and remains open. The Company has drill-tested the area up to 300 meters (980 ft) north and 535 meters (1,750 ft) wide. Metallurgical drill hole RH25C-261 intersected 2.87 g/t Au over 17.3 meters (50 gram meters) in the northeast Project area. The Metallurgical drill testing program provides valuable information for mine planning and supports validation of the current resources. \"We're pleased with the results of expansion drilling in the northern Project area which have highlighted significant high-grade gold mineralization. These results will be incorporated into the updated resource model and inform the ongoing Feasibility Study. Drilling will pause briefly for the remainder of December and resume mid-January 2026. We look forward to sharing the remaining assay results from the 2025 campaign in the n...
