Dakota Gold Continues to Advance Richmond Hill with 2025 Drill Campaign and Metallurgical Test Program

Core Insights - Dakota Gold Corp. is advancing its Richmond Hill Oxide Heap Leach Gold Project with a 2025 drill campaign and metallurgical test program, aiming to drill approximately 27,500 meters (about 90,000 feet) using Reverse Circulation and Core drilling methods [1][3][5] Drilling Campaign - The 2025 drill campaign is focused on the northern portion of the Richmond Hill Project area, with Core drilling aimed at collecting metallurgical samples, condemnation drilling for mine planning, infill drilling to upgrade existing resources, and expansion drilling where resources remain open [3][5] - Significant drill results include hole RH25C-171, which intercepted 1.50 grams per tonne gold (g/t Au) over 62.1 meters, indicating higher grades than the average resource grade of 0.463 g/t Au [5][8] - The northeast Project area is expected to yield assay results from expansion and infill drilling of higher-grade zones before the end of the year [5][8] Metallurgical Testing - The metallurgical testwork is being accelerated, with initial composite samples sent for column testing, and results expected before year-end to inform further drilling and testwork for 2026 [5][11] - The Company has appointed Mike Eiselein as Vice President of Project Development to oversee the metallurgical program, bringing over 34 years of relevant experience [10][11] Resource Expansion Potential - Condemnation drilling under historical leach pads shows potential for pit expansion, with drill hole RH25C-183 intersecting 1.82 g/t Au over 10.8 meters outside the current mine plan [8][11] - The ongoing drilling efforts are expected to refine the geo-metallurgical model and improve the precision of mine planning [7][11] Future Plans - The Feasibility Study for the Richmond Hill Project is expected to be completed in early 2027, with the current drill campaign contributing valuable data [3][5] - Dakota Gold aims to advance the Richmond Hill Project to commercial production by 2029, alongside outlining a high-grade underground gold resource at the Maitland Gold Project [20]
