Dakota Gold (DC) Corporate presentation summary

Strategic vision and project overview

• Focused on revitalizing the historic Homestake District in South Dakota with responsible gold exploration and development, targeting both the Richmond Hill and Maitland projects.

• Richmond Hill is one of the largest undeveloped heap leach gold resources in the U.S., with production targeted for 2029 and robust economics outlined in the Initial Assessment.

• Maitland offers high-grade gold exploration potential, with infill drilling and a maiden resource expected in H1 2027.

• Projects are located on private land with existing infrastructure and access to a skilled local workforce.

• $99M cash balance as of June 30, 2026, funds activities through feasibility.

Resource estimates and project economics

• Richmond Hill heap leachable resource: 3.65 Moz M&I gold, 2.61 Moz inferred gold, 38.1 Moz M&I silver, 22.8 Moz inferred silver.

• Combined heap leach and mill resource: 4.64 Moz M&I gold, 5.06 Moz inferred gold, 47.8 Moz M&I silver, 52.1 Moz inferred silver.

• After-tax NPV (5%) up to $2.1B, IRR up to 59%, initial capital ~$383M, LOM AISC ~$1,050/oz, mine life up to 28 years.

• Life-of-mine gold production up to 3.98 Moz, average annual production up to 153,000 oz.

• Projected enterprise value could reach $2.3B at full production, aligning with senior producer benchmarks.

Exploration and drilling highlights

• 2025–2026 drill campaigns added ~30% new data, with 46,552 meters drilled across 354 holes.

• Expansion drilling identified high-grade intervals, confirming mineralization remains open to the north and at depth.

• Drilling aims to convert inferred to indicated resources and extend high-grade zones, especially at Chism Gulch and Cole Creek.

• Maitland’s JB Gold Zone shows grades up to 167 g/t Au, analogous to the historic West Ledge System.

• Unionville Zone at Maitland features continuous epithermal gold mineralization, open in all directions, with infill drilling planned for 2026.
