Dakota Gold Corp. Intercepts 3.94 Grams/Tonne Gold over 9.3 Meters of Additional Tertiary Epithermal Mineralization Located over 1,400 Meters North of the Unionville Zone Discovery Area

Lead, South Dakota--(Newsfile Corp. - May 23, 2024) - Dakota Gold Corp. (NYSE American: DC) ("Dakota Gold" or the "Company") is pleased to announce that it continues to encounter Tertiary epithermal gold mineralization associated with the Unionville Zone at the Maitland Gold Project ("Maitland") in South Dakota. Notably positive results from step-out hole MA24C-040, located more than 1,400 meters north of the Unionville Zone discovery area, supports the premise that Tertiary mineralization potential exists throughout Maitland.

Significant Highlights (See Table 1):

• Step-out drill hole MA24C-040 intersected 3.94 grams/tonne gold (g/t Au) over 9.3 meters of Tertiary mineralization 148 meters below the surface. Mineralization is open north, south and to depth.

• Drill holes MA24C-041 and MA24C-042 located in the central part of the Unionville Zone returned higher-grade intercepts including 4.08 g/t Au over 2.7 meters and 7.37 g/t Au over 1 meter of Tertiary epithermal mineralization, respectively.

• Numerous structures, including the historical Maitland Mine structure, remain untested along strike and illustrate the larger potential for Tertiary epithermal mineralization at the Maitland Project. The Maitland Mine produced more than 200,000 ounces of Tertiary gold before 1945 when it was closed due to WWII.

• The Unionville Zone target extension strike length could extend more than 3,000 meters and is open along strike both to the north and south of the discovery area.

James Berry, Vice President Exploration of Dakota Gold, said, "We continue to be impressed by the quality and extent of Tertiary epithermal gold mineralization in the Maitland area. Dakota Gold has now identified gold mineralization from surface through the entire stratigraphic sequence into the Pre-Cambrian basement. Gold mineralization occurs in numerous parallel north-south structures and is relatively shallow with locally high grades and has high potential to be developed into an economic deposit with further work."

The Company currently has four drills on site at its properties in the Homestake District of South Dakota. The Unionville Zone drilling is testing for Tertiary epithermal gold mineralization and is one of three ongoing programs being advanced by the Company - the other two being Homestake Mine-Style gold mineralization in the JB Gold Zone at Maitland and the infill and step-out drilling at the Richmond Hill Gold Project to update to the S-K 1300 resource estimate.

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 Maitland Gold Project are conceptual in nature and could change as the proposed exploration activities are completed. There has been insufficient exploration of the Maitland 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 Maitland 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. 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. Check samples are submitted to Bureau Veritas, Vancouver B.C. as an umpire laboratory. Assay results are reviewed, and discrepancies are investigated prior to incorporation into the Company database.
