Dakota Gold Intersects 1.42 g/t Gold and 5.97 g/t Silver over 64.0 Meters with Infill Drilling at Richmond Hill Ready to Announce with Confidence?
Lead, South Dakota--(Newsfile Corp. - April 21, 2026) - Dakota Gold Corp. (NYSE American: DC) ("Dakota Gold" or the "Company") is pleased to report the initial assay results received from its 2026 Drill Campaign ("Campaign") at the Richmond Hill Oxide Heap Leach Gold Project ("Richmond Hill" or the "Project"). The Campaign includes 15,481 meters of drilling for 109 holes and consists of a combination of infill, expansion and geotechnical drilling. Gold and silver assay results from the 2025 and 2026 drill campaigns at Richmond Hill will be incorporated into a Pre-Feasibility Study ("PFS") being published in the second half of 2026.
Highlights from this update include:
Infill drill hole RH26C-388 intersected 1.42 grams per tonne gold (g/t Au) and 5.97 g/t silver (Ag) over 64 meters (91 gram meters Au) and RH26C-396 intersected 2.37 g/t Au and 24.80 g/t Ag over 21.5 meters (51 gram meters Au). Many higher-grade gold mineralization intersections have been encountered in the 2025 and 2026 drill campaigns that exceed the average grade of 0.566 g/t Au published in the July 7, 2025 Initial Assessment with Cash Flow ("IACF"). These above average-grade intersections have the potential to positively impact mine sequencing within the PFS and are being considered in the current trade-off studies.
The initial assay results reported today are primarily from infill drilling in the northern portion of the Project designed to support reserve conversion planned for 2026. This drilling targets areas of previously defined near-surface mineralization where tighter drill spacing is expected to support conversion of inferred resources to the indicated resource category.
Over 75% of the total planned drilling for this year's Richmond Hill Campaign has been completed to date with 11,982 meters in 80 drill holes. Drilling productivity and assay turnaround times remain on track, and the Campaign is expected to be completed in the third quarter of 2026.
Jack Henris, President and COO of Dakota Gold said, "We are pleased with the progress of the Campaign which is now advancing northeast to follow-up on higher-grade gold drill intercepts, as well as to conduct further resource expansion in the area. Upon completion of this resource drilling, we plan to commence geotechnical drilling in early May. The PFS will incorporate new assay information from over 350 drill holes from the 2025 and ongoing 2026 drill campaigns. This drilling represents up to approximately 30% new assay information relative to the mineral resource estimate published in the IACF, and it is expected to provide input for optimizing mine planning and sequencing. As we move toward completion of the PFS, we will illustrate Richmond Hill to be a technically robust, de-risked oxide heap leach gold project with a clear pathway to production."
