CEO.CA Chairman's Briefing

Lead, South Dakota--(Newsfile Corp. - March 20, 2024) - Dakota Gold Corp. (NYSE American: DC) ("Dakota Gold" or the "Company") is pleased to report assays from an additional eleven drill holes from the Maitland Gold Project ("Maitland") in South Dakota. The results from these drill holes demonstrate continuity of the Tertiary epithermal gold mineralization in the Unionville Zone at Maitland discovered in drill hole MA22C-009 (3.57 grams/tonne Gold over 36.48 meters) and announced February 8, 2023. This type of mineralization was never pursued in the historical 40-million-ounce gold producing Homestake Mine located approximately 3 miles (~4,800 meters) to the south, and it represents an underexplored opportunity for the Company at Maitland and elsewhere on the Company's other project areas in the Homestake District.

Significant Highlights (See Table 1):

• Step-out drill hole MA23C-023, completed over 2,000 feet (~600 meters) to the north of MA22C-009, returned 6.24 grams/tonne Gold over 2.6 meters, indicating a significant extension of the Tertiary gold mineralization at Maitland.

• Infill drill holes MA23C-028 and MA24C-035, completed south and north of the Unionville Zone discovery hole, returned 4.44 grams/tonne Gold over 15.3 meters (including 6.47 grams/tonne Gold over 9.6 meters) and 7.24 grams/tonne Gold over 7.3 meters, respectively.

• The Unionville Zone remains open to the north and south with an ultimate strike length that could exceed 2 miles (~3,200 meters). Also, epithermal gold mineralization occurs along parallel structures found in the historic Maitland Gold Mine to the east and undrilled parallel structures west of the Unionville Zone discovery.

James Berry, Vice President Exploration of Dakota Gold, said, "The Tertiary epithermal gold mineralization is close to surface, and contains a mix of oxide and sulfide mineralization. The opportunity we see at Maitland is unique in that we have the possibility to access two distinct types of mineralization, Tertiary-age epithermal mineralization near surface and Precambrian-age, Homestake Mine-style mineralization at depth. Tertiary mineralization has the potential to provide a strategic entryway for exploration to the Homestake Mine-style gold mineralization encountered below. The Tertiary mineralization at Maitland continues to grow, and it remains open and underexplored." Berry continued, "Drill results to date have only partially tested 4,000 feet (~1,200 meters) of the potential 2 miles (~3,200 meters) of Tertiary epithermal mineralization as defined by historical drill holes and surface rock chip geochemistry."

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 (~3,700 meters) west of Maitland and 1.5 miles (~2,400 meters) 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 (0.89 grams/tonne) in 2023. Richmond Hill and Maitland are located on private land and provide operational synergies due to their proximity.

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.
