Dakota Gold Corp. Intersects 0.060 oz/ton Gold over 144.8 feet (2.06 grams/tonne over 44.1 meters) of Tertiary Epithermal Gold Mineralization at its Maitland Gold Project

PRESS RELEASE
Published September 27, 2023

Lead, South Dakota--(Newsfile Corp. - September 27, 2023) - Dakota Gold Corp. (NYSE American: DC) ("Dakota Gold" or the "Company") is pleased to report assay results from drill holes MA23C-011, MA23C-012, MA23C-013, and MA23C-014 at the Maitland Gold Project ("Maitland"). These holes were designed to test the Unionville Tertiary-aged epithermal gold mineralization with tighter hole spacing. The results from these drill holes demonstrate exceptional continuity of the gold mineralization along the structural trend that defines the Unionville Zone. Additionally, the two intercepts reported in MA23C-012 and MA23C-013 have identified new zones of Homestake Mine-style gold mineralization along the western fringe of the structural corridor that has now been extended by drilling a distance approximately 3.1 miles (5.0 km) northwest of the +40-million-ounce historic Homestake Mine.

Highlights (See Table 1):

  • In-fill drilling (MA22C-009, MA23C-011, MA23C-012, MA23C-013, and MA23C-014) between the widely spaced early intercepts in MA22C-001, MA23C-002, MA23C-003, and MA23C-007 verify that the Tertiary epithermal gold mineralization of the Unionville Zone is continuous along a significant north-south structure that appears to control the mineralization. Drill results to date have only tested 2,000 feet of the potential 11,000 feet of Tertiary epithermal mineralization.
  • MA23C-012 and MA23C-013 identified new zones of Homestake Mine-style gold mineralization at the western margins of the structural corridor that extends northward from the Homestake Mine. The number of Homestake-style Precambrian gold mineralization intercepts at Maitland are similar to what is found at the Homestake Mine.
  • The Maitland Drill Program is now transitioning from widely spaced drill holes designed to define stratigraphy, to more tightly spaced drilling on the JB Gold Zone and the Unionville Zone discoveries (see May 4, 2023, and February 8, 2023, press releases).
  • The Company plans to move one drill from the Richmond Hill Gold Project to Maitland to drill the Unionville Zone at tighter spacing in advance of developing a maiden resource.

James Berry, Vice President Exploration of Dakota Gold, said, "We are pleased that the Unionville Zone Tertiary epithermal gold mineralization appears to connect between our wider spaced first pass drilling. The presence of Homestake Mine-style mineralization in MA23C-012 and MA23C-013 provide continued evidence that the Homestake Mine-style Precambrian orogenic gold system is present at Maitland."

Jerry Aberle, COO and Director of Dakota Gold, commented, "We are extremely pleased with drill results from the first phase of exploration at the Maitland Gold Project. The early success of our programs is allowing us to plan and implement aggressive follow-up programs that we believe will build substantial value in Dakota Gold in the near term."

Technical Update:

MA23C-011 was designed to test the continuity of the Tertiary epithermal gold mineralization in the Unionville Zone encountered in the wider spaced Phase 1 drilling. MA23C-011 intersected 0.062 oz/ton Au over 31.4 feet (2.13 grams/tonne over 9.6 meters) of Tertiary epithermal gold mineralization.

MA23C-012, drilled from the same pad as MA23C-011, intersected 0.034 oz/ton Au over 36.2 feet (1.17 grams/tonne over 11.0 meters) and 0.058 oz/ton Au over 54.5 feet (1.99 grams/tonne over 16.6 meters) of Tertiary epithermal gold mineralization. The Tertiary epithermal gold mineralization was hosted in the Cambrian/Ordovician Deadwood Formation and the Precambrian basement. MA23C-012 intersected 0.073 oz/ton Au over 74.3 feet (2.50 grams/tonne over 22.6 meters) of Homestake Mine-style orogenic gold mineralization associated with quartz-ankerite veins containing arsenopyrite and pyrite. This intercept included a higher-grade zone of 0.107 oz/ton Au over 43.6 feet (3.67 grams/tonne over 13.3 meters).

MA23C-013 was drilled 460 feet (140.2 meters) northwest of MA23C-011 and intersected 0.060 oz/ton Au over 144.8 feet (2.06 grams/tonne over 44.1 meters) of Tertiary epithermal gold mineralization. MA23C-013 intersected 0.110 oz/ton Au over 5.5 feet (3.77 grams/tonne over 1.7 meters) of Homestake Mine-style orogenic gold mineralization.

MA23C-014 was drilled 507 feet (154.5 meters) north of MA23C-011 and intersected 0.027 oz/ton Au over 75.0 feet (0.93 grams/tonne over 22.9 meters) and 0.044 over 43.0 feet (1.51 grams/tonne over 13.1 meters) of Tertiary epithermal gold mineralization.

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 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 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.
