Dakota Gold Corp. Intercepts 3.33 Grams/Tonne Gold over 9.9 Meters of Tertiary Epithermal Mineralization in the Unionville Zone

Lead, South Dakota--(Newsfile Corp. - July 9, 2024) - Dakota Gold Corp. (NYSE American: DC) ("Dakota Gold" or the "Company") is pleased to announce that it has intersected additional higher-grade Tertiary epithermal gold mineralization associated with the Unionville Zone at the Maitland Gold Project ("Maitland") in South Dakota.

Significant Highlights (See Table 1):

• Drill holes MA24C-049 intersected 3.33 grams/tonne gold (g/t Au) over 9.9 meters and 1.51 g/t Au over 19.1 meters, and MA24C-050 intersected 3.50 g/t Au over 6.1 meters of shallow Tertiary epithermal mineralization.

• Prior reporting shows higher-grade intersections including 3.57 g/t Au over 36.48 meters of Tertiary epithermal mineralization along the Unionville Zone structure which was announced with the discovery hole MA22C-009 on Feb 8th, 2023.

• Tertiary epithermal mineralization in the Unionville Zone, as well as in parallel structures remain open along strike in both directions and indicate widespread mineralization throughout the Maitland Gold Project.

James Berry, Vice President Exploration of Dakota Gold, said, "While Homestake Mine-style gold mineralization remains the primary focus of the Maitland exploration program, we continue to encounter shallow Tertiary epithermal gold mineralization in the Unionville Zone in the same areas where we are targeting deeper Homestake Mine-style mineralization. This means that we are often able to target two types of mineralization in the same hole, providing Dakota Gold with exceptional optionality. Furthermore, as we continue to explore Maitland, we expect to encounter additional parallel structures adding to the potential extension strike length that is already in excess of 3,000 meters and is open to the north and south."

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 the S-K 1300 resource estimate. The Unionville Zone at Maitland is approximately 2,100 meters east of the Richmond Hill Gold Project, which also contains Tertiary mineralization.

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.
