Dakota Gold Intersects Excessive-Grade Gold Mineralization in Enlargement Drilling at Richmond Hill

Dakota Gold Corp. (NYSE American: DC) (“Dakota Gold” or the “Firm”) is happy to report assay outcomes from 26 drill holes accomplished as a part of its ongoing 2025 drilling marketing campaign on the Richmond Hill Oxide Heap Leach Gold Venture (“Richmond Hill” or the “Venture”). These outcomes embody the primary assays from enlargement drilling within the northeast nook of the Venture.

Drilling continues to substantiate high-grade gold mineralization within the northern portion of Richmond Hill, supporting the Firm’s plan to prioritize preliminary mining on this space. Dakota Gold presently has two drills working on website and expects to finish roughly 27,500 meters (~90,000 ft) of drilling in the course of the 2025 marketing campaign.

Highlights from this replace embody:

• Enlargement and infill drill holes within the northeastern nook of the Venture space are intersecting considerably higher-grade gold than the common useful resource grade together with RH25C-278 intersecting 1.75 grams per tonne gold (g/t Au) over 19.9 meters (35 gram meters) and RH25C-295 intersecting 2.15 g/t Au over 30.0 meters (65 gram meters). The enlargement drilling surrounding the world has the potential so as to add to the useful resource based mostly on prior drilling and present assets within the space. The mineralization within the northeast is just restricted by drilling and stays open.

• Metallurgical drill holes throughout the northern Venture space proceed to intercept high-grade gold, de-risking the Venture and offering higher confidence within the useful resource together with RH25C-270 intersecting 2.26 g/t Au over 29.2 meters (66 gram meters) and RH25C-288 intersecting 4.15 g/t Au over 14.5 meters (60 gram meters). The metallurgical drilling outcomes show the low-risk nature of the deposit with widespread mineralization.

“The drill outcomes introduced right now proceed to validate the dimensions and high quality of Richmond Hill, which hosts one of many largest undeveloped heap leach gold assets in america” mentioned Jack Henris, President and COO of Dakota Gold. “The continuity and pervasive nature of the close to floor deposit help a challenge that’s low-cost, long-life, and delivers high-margins, as highlighted in our Preliminary Evaluation with Money Move earlier this 12 months. With metallurgical drilling for the 2025 marketing campaign now full, we’re advancing heap leach column testing and sit up for sharing these outcomes as they’re accomplished.”

The Firm’s core drilling stays energetic within the northeast Venture space the place we could have extra assay outcomes from enlargement and infill of the unconstrained mineralization by the fourth quarter of 2025 and into 2026. The core drilling on the Venture is designed to gather metallurgical samples for column testing, condemnation drilling beneath proposed website infrastructure for mine planning, infill drilling to improve the prevailing useful resource, and enlargement drilling the place the useful resource stays open. The drill outcomes will inform each the oxide and sulfide useful resource updates for the Feasibility Research.

The group of assay outcomes reported right now in Determine 1 embody assay outcomes from metallurgical drilling within the northern Venture space. The drill outcomes will refine the modelled boundaries and enhance the precision of the geo-metallurgical domains for the Feasibility and mine planning. As well as, the holes had been designed to accumulate samples for metallurgical exams starting from low to high-grade, numerous rock varieties, in addition to oxide, transitional, and sulfide in order that composites may be made for heap leach column exams.
