Dakota Gold Corp. Announces Further Positive Drilling Results from the Richmond Hill Gold Project

Significant Highlights (See Table 1):

• RH23C-024 and RH23C-026 successfully expanded mineralization and returned numerous intervals with significant grades proving that the Turnaround Breccia is pervasively mineralized. RH23C-024 intersected 0.049 oz/ton Au over 37.7 feet (1.68 grams/tonne over 11.5 meters), and RH23C-026 intersected 0.030 oz/ton Au over 71.1 feet (1.04 grams/tonne over 21.7 meters).

• RH23C-074 was an offset of RH23C-016, a drill hole announced on September 7, 2023, which had a length weighted average of 0.028 oz/ton Au over 1,007 feet (0.95 grams/tonne over 306.9 meters) in the MW3 Main Zone. RH23C-074 confirmed higher grade near surface oxide mineralization intersecting 0.049 oz/ton Au over 199.9 feet (1.68 grams/tonne over 60.9 meters). These drill holes combined with other holes in the MW3 Main Zone area illustrate the presence of higher grade structures with thicker contiguous intervals.

James Berry, Vice President Exploration of Dakota Gold, said, "The mineralization found in RH23C-074 confirms earlier results and, more significantly, shows that high-grade oxide mineralization is present near surface at Richmond Hill. Understanding the orientation of mineralizing feeders and projecting them into prospective geologic areas, such as favorable host rocks, is proving to be an effective tool for targeting our exploration at Richmond Hill. The Precambrian hosted gold mineralization at Richmond Hill is located within and around the breccia pipes. We have additional exploration opportunities at other breccia pipes and yet to be discovered pipes beneath cover. Our focus is now on finishing the initial Richmond Hill S-K 1300 resource estimate early in Q2 2024, but work will begin to expand it using all the great results we've reported here and in our last few news releases for the Richmond Hill Gold Project."

The results from RH23C-074 will not be included in the current S-K 1300 maiden Richmond Hill resource expected to be released in early Q2 2024, as they were received after the cutoff date for drill data to be used in the calculation. Accordingly, these results have the potential to expand the resource in future estimates. All holes from the 2023 drilling campaign drilled around the historical resource area are now reported.

The Company currently has four drills on site at its properties in the Homestake District of South Dakota. Richmond Hill is located 2.3 miles west of Maitland and 1.5 miles north of Coeur Mining Inc.'s Wharf Mine. Based on Coeur Mining Inc.'s Form 10-K Full-Year 2023 Reported Results, the Wharf Mine produced 93,502 ounces at 0.026 oz/ton gold in 2023. Richmond Hill and Maitland are located on private land and provide operational synergies due to their proximity.

Qualified Person and S-K 1300 Disclosure

James M. Berry, a Registered Member of SME and Vice President of Exploration of Dakota Gold Corp., is the Company's designated qualified person for this news release as defined in Subpart 1300 - Disclosure by Registrants Engaged in Mining Operations of Regulation S-K and has reviewed and approved its scientific and technical content.

The ranges of potential tonnage and grade (or quality) disclosed above in respect of the Richmond Hill Gold Project are conceptual in nature and could change as the proposed exploration activities are completed. There has been insufficient exploration of the Richmond Hill Gold Project to allow for an estimate of a mineral resource and it is uncertain if further exploration will result in the estimation of a mineral resource. The disclosure above in respect of the Richmond Hill Gold Project therefore does not represent, and should not be construed to be, an estimate of a mineral resource or mineral reserve.

Quality Assurance/Quality Control consists of regular insertion of certified reference materials, duplicate samples, and blanks into the sample stream. Check samples will be submitted to an umpire laboratory as the drill program progresses. Assay results are reviewed, and discrepancies are investigated prior to incorporation into the Company database. Samples are submitted to the ALS Geochemistry sample preparation facility in Winnipeg, Manitoba. Gold and multi-element analyses are performed at the ALS Geochemistry laboratory in Vancouver, British Columbia. ALS Minerals is an ISO/IEC 17025:2017 accredited lab.
