Further Resource Expansion At Richmond Hill

LEAD, SD - Dakota Gold Corp. reported on thirteen drill holes from the ongoing infill and step-out drill program to expand the maiden resource at the Richmond Hill Gold Project. The results from the drill program will be incorporated into an updated S-K 1300 Initial Assessment 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.

The drill results reported in this release are from the northeast corner of the Richmond Hill resource area known as Chism Gulch, where there has been limited drill testing by the Company. Results to date show areas of mineralization where the grade and width are higher in average than the results reported in the maiden resource.

Highlighted intersections include: RH24C-110 intersected - 4.14 g/t Au over 10.2 meters; RH24C-115 intersected - 1.84 g/t Au over 10.5 meters; and RH24C-118 intersected - 1.99 g/t Au over 13.4 meters.

The resource shell remains open in all directions and has potential for significant growth through additional drilling, metallurgical work to improve recoveries, and inclusion of silver in the updated resource. The Company continues to do infill drilling, where the original resource block model has gaps, and expand the resource to step-out areas such as Chism Gulch where we are encountering higher grade oxide gold mineralization. The infill and step-out drilling at Richmond Hill is on track to produce an updated resource which will be informed by a historical database containing 56,771 gold assays from 910 drill holes, with the addition of 145 drill holes totaling 45,517 meters of drilling by the current drill programs.

Robert Quartermain, Co-Chair, President and CEO, said, "The Richmond Hill Oxide Heap Leach Gold Project continues to exceed our expectations through the drill results we are announcing. We will complete our drill campaign at Richmond Hill and we expect to see an appropriate increase in our planned resource update which Dakota Gold will announce in approximately 10 weeks. We envision Richmond Hill to be a low cost surface oxide heap leach operation. The operation will be a 15 to 20 minute drive from our head office in Lead, South Dakota where we have an expert team who can advance the project along the production track all the while unlocking value at our adjacent Maitland project."
