• The Initial Assessment outlines a heap leachable resource of 3.65 million ounces of measured and indicated gold, plus 2.61 million ounces of inferred gold.
• The report also identifies a combined heap leach and milled measured and indicated resource of 4.64 million ounces and a combined heap leach and milled inferred resource of 5.06 million ounces.
• The company plans to release an Initial Assessment with Cash Flow (IACF) analysis in mid-2025, outlining a potential at-surface heap leach operation.
• Barrick Gold has agreed to extend the option period for the Richmond Hill and Homestake option agreements until December 31, 2028, with additional annual payments.
• The company expects to advance the project through economic studies to feasibility and into commercial production as soon as 2029.
• The project benefits from its location on private land with existing infrastructure, near the city of Lead, South Dakota.

Sentiment

Score: 9

Explanation: The document is highly positive due to the significant increase in the resource estimate, the potential for near-term production, and the extension of the option agreement with Barrick Gold. The management comments are also optimistic.

Positives

• The project is located on private land with existing infrastructure.
• The mineralization is shallow, with portions exposed at or near the surface.
• The company has a non-binding financial proposal for up to $300 million from Orion Mine Finance.
• The heap leachable resource remains open to the north and in the southeast area of Richmond Hill.

Risks

• The company's ability to achieve its strategic goals.
• The state of the economy and financial markets generally and the effect on the company's industry.
• The market for the company's common stock.

Future Outlook

Dakota Gold expects to advance the Richmond Hill project through economic studies to feasibility and into commercial production as soon as 2029. The company also anticipates further resource expansion in 2025 with additional drilling.

Management Comments

• Dr. Robert Quartermain stated that the heap leachable resource is transformational for Dakota Gold and forms the platform from which they can grow and expand their mining and exploration activities in the Homestake District.
• James Berry commented that the results of the new resource have exceeded their expectations and showcase the extent and quality of the Project mineralization.

Industry Context

The announcement references Coeur Mining's Wharf Mine, located 5 km south of Richmond Hill, as a comparable heap leach operation. This provides context for the potential economic viability of a similar operation at Richmond Hill.

Comparison to Industry Standards

• The announcement compares the Richmond Hill project to Coeur Mining's Wharf Mine, which is expected to generate over $100 million in free cash flow in 2024 from approximately 90,000 ounces of gold.
• This comparison suggests that Dakota Gold believes Richmond Hill has the potential to achieve similar economic performance.

Stakeholder Impact

• The project has the potential to generate significant free cash flow once in production, which benefits all stakeholders including shareholders, local communities and the State of South Dakota.

Next Steps

• Release of Initial Assessment with Cash Flow (IACF) analysis planned for mid-2025.
• Initiating a full feasibility study in mid-2025.
• Undertaking baseline environmental studies to inform future permitting requirements.
• Follow-up drilling in the northeastern portion of the Project and other target areas.
• Expanding the resource with material amenable to heap leaching.
• Converting resource to reserves and gathering additional metallurgical data.
