Dakota Gold Corp.: Dakota Gold Reports Further Resource Expansion at Richmond Hill with Step-Out Drilling Results

Lead, South Dakota--(Newsfile Corp. - November 26, 2024) - Dakota Gold Corp. (NYSE American: DC) ("Dakota Gold" or the "Company") is pleased to announce results of thirteen drill holes from the ongoing infill and step-out drill program to expand the maiden resource at the Richmond Hill Gold Project ("Richmond Hill"). The results from the drill program will be incorporated into an updated S-K 1300 Initial Assessment ("Initial Assessment or Report") in Q1 2025. The maiden S-K 1300 resource, which was announced on April 30, 2024 outlined an 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.

Highlights:

• The drill results reported in this release are from the northeast corner of the Richmond Hill resource area known as Chism Gulch, where there has been limited drill testing by the Company. Results to date show areas of mineralization where the grade and width are higher in average than the results reported in our maiden resource.

Highlighted intersections include:

• RH24C-110 intersected - 4.14 g/t Au over 10.2 meters
• RH24C-115 intersected - 1.84 g/t Au over 10.5 meters
• RH24C-118 intersected - 1.99 g/t Au over 13.4 meters

• The resource shell remains open in all directions and has potential for significant growth through additional drilling, metallurgical work to improve recoveries, and inclusion of silver in the updated resource. We continue to do infill drilling, where the original resource block model has gaps (refer to News Release on Nov 4, 2024), and expand the resource to step-out areas such as Chism Gulch where we are encountering higher grade oxide gold mineralization.

• The infill and step-out drilling at Richmond Hill is on track to produce an updated resource which will be informed by a historical database containing 56,771 gold assays from 910 drill holes, with the addition of 145 drill holes totaling 45,517 meters of drilling by Dakota Gold's current drill programs.

Dr. Robert Quartermain, Co-Chair, President and CEO stated, "The Richmond Hill Oxide Heap Leach Gold Project continues to exceed our expectations through the drill results we are announcing today and in our recent news releases. We will complete our drill campaign at Richmond Hill this month and we expect to see an appropriate increase in our planned resource update which Dakota Gold will announce in approximately 10 weeks." Dr. Quartermain continued, "We envision Richmond Hill to be a low cost surface oxide heap leach operation similar to the adjacent Wharf Mine operated by Coeur Mining located in an existing mining camp with available infrastructure. The operation will be a 15 to 20 minute drive from our head office in Lead, South Dakota where we have an expert team who can advance the project along the production track all the while unlocking value at our adjacent Maitland project."

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.

Maitland Gold Project

Regarding Dakota Gold's other focus area, 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 just 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.
