Dakota Gold Corp. Announces 9.46 grams/tonne gold over 6.4 meters of Homestake Mine-Style Gold Mineralization at the Maitland Gold Project

Lead, June 20, 2024 - Dakota Gold Corp. (NYSE American: DC) ("Dakota Gold" or the "Company") is pleased to announce that it has intersected additional high-grade Homestake Mine-style gold mineralization within the ledges of the JB Gold Zone at the Maitland Gold Project ("Maitland") in South Dakota.

Significant Highlights (See Table 1):

• The growing array of drill holes targeting Homestake Mine-style gold mineralization has produced multiple high-grade gold intercepts in at least three distinct ledges within the JB Gold Zone at Maitland: 34 Ledge, 35 Ledge and 36 Ledge.

• Drill hole MA24C-050 returned 9.46 grams/tonne (g/t) gold over 6.4 meters within the 36 Ledge. The intersection is a 66.1 meter lateral offset towards the north and a 51.2 meter vertical offset above previously announced drill hole MA24C-038 on April 4, 2024 which intersected 25.03 g/t gold over 4.4 meters.

• Other reported drill holes have intersected positive drill results with Homestake Mine-style mineralization within the 36 Ledge including, MA23C-021, MA23C-024, MA23C-024A, MA23C-024B, MA23C-024C, MA23C-024E, MA23C-025, and MA24C-049. Drill holes MA23C-031, MA24C-037 and MA24C-046 appear to be in an east limb of the 35 Ledge system.

• Drilling at Maitland continues to transition from wider spacing of approximately 250 meters, to tighter spacing to further delineate the mineralization within identified ledges, which remain open along strike and to depth.

James Berry, Vice President Exploration of Dakota Gold, said, "These results further support our belief that Homestake Mine-style gold mineralization in the JB Gold Zone at Maitland is analogous to the gold mineralization found in the 'West Ledge' system at the historic Homestake Mine that produced approximately 6 million ounces of gold. As we have previously noted, in the West Ledge, the best grades were encountered at depths that Dakota Gold's exploration programs have yet to drill test at Maitland. We look forward to continuing to expand upon our drill programs success through the remainder of 2024."

The Company currently has four drills on site at its properties in the Homestake District of South Dakota. The JB Gold Zone drilling is testing for Homestake Mine-Style gold mineralization and is one of three ongoing programs being advanced by the Company - the other two being Tertiary epithermal gold mineralization in the Unionville 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.

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.
