Dakota Gold Corp. Announces Additional Positive Drill Results from Infill Program at Richmond Hill Gold Project

Lead, November 4, 2024 - Dakota Gold Corp. (NYSE American: DC) ("Dakota Gold" or the "Company") is pleased to announce drill results from the initial seventeen holes from the larger-ongoing infill drill program to expand the maiden resource at the Richmond Hill Gold Project ("Richmond Hill"). The results from the infill drill program will be incorporated into an updated S-K 1300 Initial Assessment ("Initial Assessment or Report") in Q1 2025. The maiden S-K 1300 resource, which was announced on April 30, 2024 outlined an Indicated Resource of 51.83 million tonnes (Mt) at 0.80 grams per tonne gold (g/t Au) for 1.33 million ounces and Inferred Resource of 58.06 million tonnes (Mt) at 0.61 grams per tonne gold (g/t Au) for 1.13 million ounces.

Highlights:

• The initial infill drill results have encountered further gold mineralization from the central portion of the Richmond Hill resource area, consistent with results reported in our maiden resource. This drilling was conducted in areas where the original resource block model contained gaps, supporting our belief that the initial resource could be significantly expanded with additional infill drilling.

Highlighted intersections include:

• RH24C-077 intersected - 0.76 g/t Au over 24.4 meters
• RH24C-083 intersected - 0.70 g/t Au over 13.8 meters
• RH24C-085 intersected - 1.10 g/t Au over 17.9 meters
• RH24C-088A intersected - 0.96 g/t Au over 41.5 meters
• RH24C-099 intersected - 1.15 g/t Au over 51.7 meters

• The resource remains open in all directions and has potential for improvement with additional drilling, metallurgical work to improve recoveries, and incorporation of silver in the resource. To this point, our 2024 program has focused on infill drilling. We continue to have significant opportunities to step-out with expansion drilling now currently in progress at Richmond Hill.

• An updated S-K 1300 resource estimate is planned for Q1 2025 and a S-K 1300 Initial Assessment with cash flow analysis is planned for Q2 2025. We expect to include an additional 88 new drill holes totaling 17,000 meters in the updated resource.

James Berry, VP of Exploration said, "We are very pleased to see that initial results from our infill drill program are adding ounces to our current S-K 1300 resource. The results to date show grades and widths consistent with drill holes in the original block model, and support an expansion of gold mineralization including shallow oxide mineralization. We look forward to continuing our infill program on the other zones identified in our Initial Assessment for follow up drilling."

The infill and step-out drilling at the Richmond Hill Gold Project to update the S-K 1300 resource estimate is one of three ongoing drill programs being advanced by the Company - the other two being Homestake Mine-style gold mineralization in the JB Gold Zone and Tertiary epithermal gold mineralization in the Unionville Zone at Maitland. The Unionville Zone at Maitland is approximately 2,100 meters east of the Richmond Hill Gold Project, which also contains Tertiary mineralization.
