Lead, South Dakota--(Newsfile Corp. - September 7, 2023) - Dakota Gold Corp. (NYSE American: DC) ("Dakota Gold" or the "Company") is pleased to report assays from nine drill holes including RH23C-016 at the Richmond Hill Gold Project ("Richmond Hill") in South Dakota. RH23C-016 was designed to validate historical drilling and to test for a higher-grade feeder zone associated with Precambrian structures below the known near-surface MW3 Main Zone gold mineralization. The intercepts in RH23C-016 demonstrate that additional Tertiary aged, Precambrian hosted gold mineralization is present in the basement rocks underlying the Paleozoic cover rocks; which were the primary focus of historical drilling in the northern half of the Richmond Hill property.
Highlights (See Table 1):
- RH23C-016 intersected 0.102 oz/ton Au over 77.6 feet (3.50 grams/tonne over 23.7 meters) below the historical drilling at Richmond Hill. The intercept is possibly a feeder to the overlying MW3 Main Zone mineralization and adds a new exploration target at Richmond Hill. When length weighted, RH23C-016 had an average grade of 0.028 oz/ton Au (0.95 grams/tonne) over the 1,007 feet (306.9 meters) drill hole.
- RH23C-015 intersected 0.055 oz/ton Au over 61.5 feet (1.89 grams/tonne over 18.7 meters) and 0.036 oz/ton Au over 196.1 feet (1.23 grams/tonne over 59.8 meters) of Tertiary gold mineralization validating historical drill intercepts.
- The Company has completed the validation/metallurgical drill program at Richmond Hill and is awaiting assay results for the final drill holes before selecting metallurgical samples. The Company plans to return to exploration and step-out drilling now that the validation/metallurgical program has been completed.
James Berry, Vice President Exploration of Dakota Gold, said, "We are pleased with the continuing success of our Richmond Hill exploration program. Historical drilling at Richmond Hill indicates several opportunities for gold mineralization in Precambrian hosted breccia pipes, along structures within the Precambrian, and the overlying Cambrian Deadwood Formation. The mineralized basement zones, like those intercepted in RH23C-016, also return higher gold grades and are a great opportunity to improve the gold endowment at Richmond Hill. Identifying and then tracing the structures controlling the high-grade gold mineralization will be a priority for future drilling."
RH23C-016 was designed to validate historical drilling in the MW3 Main Zone area. The drill hole intersected 0.102 oz/ton Au over 77.6 feet (3.50 grams/tonne over 23.7 meters) within Tertiary fractures in the Precambrian basement rocks, beneath Tertiary replacement mineralization in the Deadwood Formation. When length weighted, RH23C-016 had an average grade of 0.028 oz/ton Au (0.95 grams/tonne) over the 1,007 feet (306.9 meters) drill hole. Step-out drilling is planned along this zone to determine the extent of the basement hosted mineralization.
RH23C-015 was designed to validate historical drilling in the MW3 Main Zone area. RH23C-015 was angled across a trend of higher-grade assays and extended into the Precambrian basement. The drill hole encountered Tertiary replacement mineralization at 41 feet (12.5 meters), Tertiary breccia mineralization at 155.1 feet (47.3 meters) and Tertiary fractured controlled mineralization in the Precambrian basement at 377.3 feet (115.0 meters).
RH23C-047 was designed to test the Turnaround Breccia area and intersected 0.053 oz/ton Au over 59.3 feet (1.82 grams/tonne over 18.1 meters) and 0.066 oz/ton Au over 37.6 feet (2.26 grams/tonne over 11.5 meters).
RH23C-049 was designed as a validation drill hole on the west side of the MW3 Main Zone area and intersected 0.042 oz/ton Au over 10.2 feet (1.44 grams/tonne over 3.1 meters) in Tertiary fractured Precambrian basement.
RH23C-050 was designed as a validation drill hole beneath the historical Richmond Hill open pit mine. RH23C-050 intersected 0.096 oz/ton Au over 21.2 feet (3.29 grams/tonne over 6.5 meters) in Tertiary fractures and breccias in the Precambrian basement.
RH23C-052 was designed to test the northern end of the MW3 East Zone area. The upper intervals were Tertiary mineralization hosted in the Cambrian Deadwood Formation. The lower intercept was in Precambrian hosted Tertiary gold mineralization.
RH23C-053 was designed to test the MW3 East Zone area and encountered Deadwood Formation hosted gold mineralization. The lower intercept of 0.106 oz/ton Au over 27.7 feet (3.63 grams/tonne over 8.4 meters) was within the lower Deadwood Formation and extends higher grade mineralization intersected in the historical drilling to the north.

The Company currently has four drills operating on its properties in the Homestake District of South Dakota, at the Maitland Gold Project (Maitland) and Richmond Hill Gold Project. The Maitland drills are targeting Homestake-hosted and Tertiary gold mineralization and the Richmond Hill drills are targeting Tertiary breccias and replacement mineralization. Richmond Hill is located 2.3 miles west of Maitland and 1.5 miles north of Coeur Mining, Inc.'s Wharf Mine.

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 Richmond Hill Gold Project are conceptual in nature and could change as the proposed exploration activities are completed. There has been insufficient exploration of the Richmond Hill 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 Richmond Hill 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. Check samples will be submitted to an umpire laboratory as the drill program progresses. Assay results are reviewed, and discrepancies are investigated prior to incorporation into the Company database. 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.
