Lead, South Dakota--(Newsfile Corp. - April 30, 2024) - Dakota Gold Corp. (NYSE American: DC) ("Dakota Gold" or the "Company") is pleased to release its S-K 1300 Initial Assessment ("Initial Assessment or Report") for the Richmond Hill Gold Project ("Richmond Hill") in South Dakota. The maiden resource in the Report was derived from a historical database containing 69,401 gold assays from more than 900 drill holes, including 57 drill holes from Dakota Gold's current drill program. The Report includes drilling that was completed prior to October 5, 2023, and has been published on the Company's website and filed by the Company with the Securities and Exchange Commission on EDGAR as an exhibit to its Current Report on Form 8-K dated April 30, 2024. The Report was prepared by an independent group of Qualified Persons under AKF Mining Services Inc., which has reviewed and approved the contents of this news release.

Highlights:

• Indicated Resource of 51.83 million tonnes (Mt) at 0.80 grams per tonne gold (g/t Au) for 1.33 million ounces and Inferred Resource of 58.06 million tonnes (Mt) at 0.61 grams per tonne gold (g/t Au) for 1.13 million ounces (see Table 1).

• Mineralization is very shallow with portions of the resource exposed at surface.

• High-grade potential - Drilling completed post Report cut off (not included in maiden resource but previously press released) includes: 22.9 meters of 1.99 g/t Au; 42.8 meters of 1.71 g/t Au; and 60.9 meters of 1.68 g/t Au.

• Growth potential - The resource is open in all directions and has potential for improvement with additional drilling, metallurgical work to improve recoveries, and incorporation of silver in the resource.

• Resource timeline - The multi-million-ounce maiden resource was outlined in less than 20 months from Dakota Gold's first hole in March 2022. Updated S-K 1300 Assessment planned for mid-2025.

Jonathan Awde, President, CEO and Director of Dakota Gold, said, "We are very pleased with the results of our maiden resource for Richmond Hill which was delivered in less than two years from the first drill hole. The mineralization is consistent, near surface with portions of the resource exposed at surface, and contains significant oxide mineralization. Richmond Hill benefits from being on private land and close to well established infrastructure. There is significant opportunity for improvement and expansion of the resource with additional work to position Richmond Hill as a high-quality, advanced-stage exploration asset in the US."

James Berry, VP of Exploration, said, "The initial drill program at Richmond Hill confirmed historical drilling and demonstrated that the mineralization is more extensive than we anticipated. We have been conservative in our methodology and are confident that the resource will expand with additional exploration and infill drilling. With inclusion of the significant silver component, and optimization of recoveries, we think the future of Richmond Hill is exceptional and a great beginning for our assets in the Homestake Gold District!"

Details of the maiden resource will be presented in a webcast conference call on Tuesday, April 30, 2024 at 11am Eastern / 9am Mountain / 8am Pacific.

Maiden Resource of 1.33 M oz of Indicated and 1.13 M oz of Inferred Gold

Table 1: Richmond Hill Conceptual Pit-Constrained Maiden Resource Estimate at Variable Cutoff Grades

See S-K 1300 Initial Assessment Table 1.1

Notes:

• Mineral resources are not mineral reserves and do not have demonstrated economic viability.
• There is no certainty that all or any part of the estimated mineral resources will be converted into mineral reserves.
• Pit-constrained resources are stated at a range of cutoff gold grades depending on oxide state.
• Oxide recovery = 87%, mixed recovery = 65%, hypogene recovery = 42%.
• Mineral resource tonnage and contained metal have been rounded to reflect the accuracy of the estimate, and numbers may not add due to rounding.
• Mineral resource tonnage and grades are reported as undiluted.
• MRE is current as of October 5, 2023.
• Pit-Constrained at $1,900/oz; Royalty = 3.8%; Mill & G&A Cost = $8.00; Mine Cost = $1.80.
• Cutoff grade Au g/t: Oxide 0.21 g/t, Mixed 0.29 g/t, Hypogene 0.44 g/t
• Pit slope at 50 degrees

Resource Growth Potential

The resource is open in all directions and has potential for expansion with additional drilling. In addition, a significant number of mineralized drill intercepts remain outside of the declared resource due to the conservative methodology, which we believe could be converted to resource with additional infill drilling.
