Lead, South Dakota--(Newsfile Corp. - December 3, 2024) - Dakota Gold Corp. (NYSE American: DC) ("Dakota Gold" or the "Company") is pleased to announce that step-out drilling north of the JB Gold Zone has nearly doubled the known strike-length of the Homestake iron-formation hosted gold mineralization at the Maitland Gold Project ("Maitland").

Dakota Gold's 2024 Maitland drill program has delineated four distinct ledges, each of which has yielded high-grade Homestake Mine-style gold intercepts analogous to the gold mineralization found in the "West Ledge" system that produced approximately 6 million ounces of gold at the historic Homestake Mine. To date, the Company's program at Maitland has generated 49 intercepts from 73 holes at an average grade of 10.11 grams per tonne gold (g/t Au) over an average thickness of 3.8 meters.

While the modeling of the Maitland gold system had previously appeared to share a similar sized footprint with the West Ledge system of the Homestake Mine, this step-out drilling has substantially extended the mineralization northward, with the system still open to further expansion to the north, south and at depth.

Significant Highlights (See Table 1):

• Step-out drill hole MA24C-058 intersected 28.10 g/t Au over 0.8 meters. MA24C-058 is located 710 meters northwest of the JB Gold Zone discovery drill hole MA23C-017, nearly doubling the length of the known mineralization.

• Other highlighted JB Gold Zone intercepts:

  • MA23C-032D intersecting - 14.45 g/t Au over 1.8 meters

  • MA24C-051 intersecting - 8.93 g/t Au over 3.5 meters

  • MA24C-055 intersecting - 11.50 g/t Au over 1.6 meters

• With the inclusion of step-out drill hole MA24C-058, the length of all mineralized ledges in the Maitland area to date is 1,646 meters long. The ledges remain open along strike and to depth.

Jerry Aberle, Chief Operating Officer commented, "The results of our drill programs at Maitland have demonstrated beyond doubt that the same mineralizing fluids that produced the Homestake Mine are repeatable and have mineralized the exact same host rocks at Maitland. Those of us that worked at the Homestake Mine or were engaged in Homestake's exploration of the corridor extending north of the mine have waited a long time for the opportunity to prove that these Homestake Mine-style deposits are repeatable. We've now demonstrated that with our results to date, and we've only just begun." Aberle continued, "With all of the Homestake data and our first-hand knowledge of that data, Dakota Gold's technical team worked up a number of solid targets within the corridor and ranked them. We chose to start our corridor program at Maitland in early 2022, and this first program has exceeded every expectation I could have had for sustained consistent results. And, we have multiple targets to the north at Blind Gold and to the south at the North Drift Discovery yet to test."

James Berry, Vice President Exploration of Dakota Gold, said, "My experience as an exploration and underground geologist working 10 years at the Homestake Mine informs my belief that the Maitland drill results identifying Ledges 34, 35, 36 and 37 are analogous to the West Ledges of the Homestake Mine. From the drill core, we are seeing steeply plunging or reclined mineralization and comparable grades and thicknesses. The Maitland mineralization is shallower than the West Ledges of the Homestake Mine which produced more than 6 million ounces of gold. The Homestake Mine is the world's largest banded iron formation hosted gold deposit and similar gold systems include Orla's Musselwhite and B2's Back River deposits. The one unique characteristic of the Maitland mineralization is it is close to infrastructure and a 15 minute drive from our head office. As we wrap up our 2024 drill program at Maitland for the year, we will be refining our modelling of the ledges and analyzing the results to create a follow up drill program for the 2025 year that will target shallower intercepts."

Maitland Gold Project

The Maitland Gold Project hosts the JB Gold Zone, which has returned highlight intercepts including drill hole MA23C-038 which intersected 25.03 g/t Au over 4.4 meters. Maitland is 3 miles along strike of the historic Homestake Mine. The JB Gold Zone discovery is analogous to the West Ledges at the Homestake Mine that produced over 6 million ounces at a grade of 7.7 g/t Au. Dakota Gold has completed its 2024 Maitland drill program and is assessing results that will inform the 2025 follow up drill program where we have significant potential to continue to expand the footprint of the high-grade gold discovered to date.

Richmond Hill Oxide Heap Leach Gold Project

Regarding Dakota Gold's other focus area, the Richmond Hill Oxide Heap Leach Gold Project, based on the current defined oxide resource and additional significant drill hole intercepts encountered in the current drill campaign, Dakota has contracted with M3, RESPEC, IMC and Woods Processing to undertake the necessary engineering and metallurgical studies currently in progress to advance from the Initial Assessment with Cash Flow (IACF) to initiating a full feasibility in Q2 2025. Concurrently the Company is undertaking baseline environmental studies that will inform future permitting requirements. With regards Richmond Hill, it is analogous to the adjacent Wharf Mine of Coeur Mining which is expected to generate over $100 million in free cash flow in 2024 from approximately 90,000 ounces of gold. The Richmond Hill Oxide Heap Leach Gold Project is located on private land with certain existing permits and we believe with anticipated updated amendments, we can advance the project expeditiously through development and into production. Our financial proposal for up to $300 million for a development opportunity with Orion Mine Finance, our major shareholder announced on October 12, 2023, provides Dakota Gold with the financial pathway to a commercial gold operation.

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. 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.
