Item 4.01 Changes in Registrant's Certifying Accountant.

On November 18, 2025, upon the completion of a competitive selection process conducted by the Audit Committee of the Board of Directors of Dakota Gold Corp. (the "Company"), the Audit Committee approved, effective immediately, (i) the appointment of Deloitte & Touche LLP ("Deloitte") as the Company's new independent registered public accounting firm for the fiscal year ending December 31, 2025 and (ii) the dismissal of Ernst & Young LLP ("EY") as the Company's independent registered public accounting firm.

EY's reports on the Company's financial statements for the fiscal years ended December 31, 2024 and 2023 did not contain an adverse opinion or a disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles. In connection with the audits of the Company's consolidated financial statements for each of the fiscal years ended December 31, 2024 and 2023, and in the subsequent interim period through November 18, 2025, there were no disagreements between the Company and EY on any matters of accounting principles or practices, financial statement disclosure, or auditing scope or procedures which, if not resolved to the satisfaction of EY would have caused EY to make reference to the matter in their report.

The Company has provided EY with a copy of the disclosures it is making in this Current Report on Form 8-K and has requested that EY furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether it agrees with the statements made herein. A copy of such letter, dated November 21, 2025, is filed as Exhibit 16.1 to this Current Report on Form 8-K.

During the Company's two most recent fiscal years ended December 31, 2024 and 2023, and the subsequent interim period through November 18, 2025, neither the Company nor anyone acting on its behalf consulted with Deloitte regarding (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company's financial statements, and neither a written report nor oral advice was provided to the Company that Deloitte concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing, or financial reporting issue, or (ii) any matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions thereto) or a reportable event (as defined in Item 304(a)(1)(v) of Regulation S-K and the related instructions thereto).
