Dakota Gold Intersects 2.22 grams per tonne gold over 50 meters at Richmond Hill in Drill Program to Expand Resource
Lead, South Dakota--(Newsfile Corp. - December 11, 2024) - Dakota Gold Corp. (NYSE American: DC) ("Dakota Gold" or the "Company") is pleased to announce results of twenty-four drill holes from the infill and step-out drill program designed to expand the maiden resource at the Richmond Hill Gold Project ("Richmond Hill") ("drill program"). The results reported today are the final assays from the drill program which began in November 2023, and they, along with the previously released 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 ("maiden 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 area of the Richmond Hill resource area known as Chism Gulch, where there has been limited drill testing by the Company. Results to date demonstrate areas of additional oxide mineralization, and the grade and width are higher in average than the drill results used to inform the maiden resource.
Highlighted intersections include:
- RH24C-122 intersected - 1.00 g/t Au over 38.2 meters
- RH24C-136 intersected - 3.30 g/t Au over 11.8 meters
- RH24C-142 intersected - 2.22 g/t Au over 50.0 meters
- RH24C-143 intersected - 2.54 g/t Au over 11.4 meters
- Drilling to date indicates that the entire Richmond Hill resource shell remains open in all directions. There is potential for significant resource growth through additional drilling, metallurgical work to improve recoveries, and inclusion of silver in the updated resource.
- Dakota Gold is on track to produce an updated S-K 1300 resource for Richmond Hill 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 program to expand the maiden resource.
James Berry, VP Exploration for Dakota Gold said, "The results received to date from our drill program have exceeded my expectations for grade and widths. Of the 52 drill hole results reported to date from the Chism Gulch area, the average grade is 1.13 g/t Au, with an average width of 10.9 meters, which is much better than the averages for drilling at Chism Gulch used to generate the maiden resource and bodes well to increase resource ounces. The Chism Gulch area remains open to the north and east. We look forward to our updated S-K 1300 resource early in the New Year, incorporating results from Chism Gulch and Twin Tunnels drilling."
"The Richmond Hill drill results reported today will contribute to a robust resource update in Q1 2025 and provide areas for future resource expansion," stated Robert Quartermain, Co-Chair, President and CEO. He continued, "With our successful step-out drilling campaign at Maitland reported in our December 3rd, 2024 news release, both of our projects align with our expectations this year, and we are well-positioned to grow shareholder value through successful exploration."
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
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 three miles along strike north of the historic Homestake Mine and gold mineralization now extends over 1,646 meters based on our recent drilling. 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.
