Dakota Gold Corp. Intersects 9.2 Feet of 0.340 Ounces per Ton Gold (2.8 Meters of 11.65 Grams per Tonne) and 37.5 Feet of 0.077 Ounces per Ton Gold (11.43 Meters of 2.64 Grams per Tonne) in Its Second Drill Hole at Its Maitland Gold Project

Lead, South Dakota--(Newsfile Corp. - September 8, 2022) - Dakota Gold Corp. (NYSE American: DC) ("Dakota Gold" or the "Company") is pleased to announce the results of its second drill hole, MA22C-002, at the Maitland Gold Project located approximately three miles north and contiguous with the Homestake Mine. MA22C-002 was designed to test for Homestake Formation, the host unit of gold mineralization at the Homestake Mine; as well as test for Homestake-style, Precambrian gold mineralization, and test for Tertiary feeder zones within the underlying Precambrian.

Drill Hole MA22C-002 Highlights:

  • Confirmed the presence of Homestake Formation and Homestake-style gold mineralization 2.8 miles north of the +40-million-ounce gold past producing Homestake Mine within the Homestake deformation corridor.

  • Intersected Tertiary mineralization within the Precambrian basement that may represent feeders to the Tertiary aged, Deadwood Formation hosted gold mineralization found above. The nearby Maitland Mine produced ~250,000 ounces at ~0.3 ounces per ton ("oz/ton") gold ("Au") from Tertiary replacement mineralization in the Deadwood Formation.

  • Dakota Gold currently has three drills operating in the district. Two drills are targeting the Homestake Corridor at Maitland and the third is testing the Basal Deadwood Property near City Creek.

  • The Company is in the process of securing a fourth drill rig for the Richmond Hill Property.

Exploration Update:

James M. Berry, Vice President of Exploration of Dakota Gold, said, "We are very pleased with the results from the second hole at Maitland. MA22C-002 demonstrates that the Precambrian, Homestake-style gold mineralization is present within the Homestake structural corridor well north of the Homestake Mine. The drill hole has also found more Tertiary mineralization within the Precambrian basement that may be feeders to the overlying Tertiary deposits," and continued, "MA-22C-002 demonstrates proof of concept by intersecting potentially economic gold mineralization in Homestake Formation in an area that previously has not been drilled. We are looking forward to advancing our Homestake District targets and providing additional drill results."

MA22C-002

MA22C-002 drill hole was designed to test the area below and north of MA22C-001 (see June 2, 2022, news release) and to further test the up-plunge projection of the North Drift discovery (Figure 1) within the structural corridor extending north of the Homestake Mine.

Several intervals of Homestake Formation, the host unit of the gold mineralization at the Homestake Mine, were encountered at various depths down the hole. Gold mineralization at the Homestake Mine is associated with quartz-carbonate veins, chlorite selvages, and arsenopyrite-pyrrhotite-pyrite sulfides. These types of key alteration have been observed within the two holes that have been completed. This type of mineralization was encountered in five intervals of MA22C-002 and two of these intervals contained significant gold values (see Table 1) that will be useful for vectoring future step-out drilling. The interval from 3,429.5 feet to 3,467 feet demonstrates the presence of Homestake-style gold mineralization 2.8 miles beyond the Homestake Mine. This interval included 5.2 feet of 0.244 oz/ton Au. Additional step-out drilling is being planned for this intercept.

Additional intercepts of Precambrian hosted Tertiary gold mineralization were encountered in MA22C-002. The best of these (9.2 feet of 0.340 oz/ton Au) was intersected at 4,103 feet down the hole and was associated with a Tertiary porphyritic dike and adjacent quartz-calcite-pyrite lined fractures. Tertiary-aged gold mineralization hosted in the Precambrian basement represents a previously untested target type within the corridor. Dakota Gold has postulated that such zones of mineralization could exhibit vertical continuity to great depth.

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. 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 Twin Falls, Idaho. Gold analyses are performed at the ALS Geochemistry laboratory in Reno, Nevada or Vancouver, British Columbia, and multi-element geochemical analysis are completed at the ALS Minerals laboratory in Vancouver, British Columbia. ALS Minerals is an ISO/IEC 17025:2017 accredited lab.
