Dakota Gold Announces Leadership Changes and Board Additions

Lead, May 19, 2025 - Dakota Gold Corp. (NYSE American: DC) ("Dakota Gold" or the "Company") is pleased to announce changes to its senior leadership team and Board of Directors. Jack Henris will be appointed President and Chief Operating Officer (COO) of Dakota Gold effective June 1, 2025 upon the retirement of Gerald Aberle, our current COO. Mr. Aberle will continue to serve on the Board of Directors. Todd Kenner and Kevin Puil were appointed to the Board of Directors effective May 15, 2025 and Amy Koenig will resign from the Board of Directors on May 31, 2025 and assume the role of Senior Vice President, Chief Legal Officer and Corporate Secretary for Dakota Gold effective June 1, 2025.

As Dakota Gold advances its Richmond Hill Heap Leach Gold Project ("Richmond Hill" or "Project") to production, the Company continues to enhance its leadership team and board composition to provide the requisite skillsets as it transitions from an exploration to development and production enterprise. As detailed in the bios below, Jack Henris has extensive operational experience in heap leach and underground operations as well as managing projects through permitting cycles. Todd Kenner is the former CEO of RESPEC, a South Dakota based engineering firm and brings his experience across a varied platform of engineering projects. Kevin Puil is a Texas-based fund manager and has the requisite capital markets experience in resource investments. Amy Koenig has extensive local and public market experience from her previous role as in-house legal counsel for Black Hills Corporation, a NYSE listed company based in South Dakota.

Dr. Robert Quartermain, Co-Chair, Director, and CEO of Dakota Gold stated, "I am pleased to announce today that Jack Henris will be joining Dakota Gold as its President and COO to guide Richmond Hill through Feasibility Study, permitting and into construction. Jack has extensive experience at both heap leach and underground gold operations, from permitting through production, bringing skillsets germane to our current stage of development. The fact that Jack has worked at the Homestake Mine and with many of our current management team, and lives in Spearfish, South Dakota, is valuable at this stage of the Company's development. In addition, Todd Kenner and Kevin Puil will be joining Dakota Gold as new independent directors, strengthening our Board." Dr. Quartermain continued, "Dakota Gold exists because of the initial efforts of Jerry Aberle. His long professional career in the Homestake District allowed him, as a founder of the Company, to assemble an impressive land package with significant gold potential. Jerry's decision to retire as COO now allows Jack to continue to build on the efforts of Jerry and the team he has put together. I want to thank Jerry and acknowledge his contribution to Dakota Gold on behalf of shareholders. We look forward to his continued contribution as a member of the Board."

Mr. Aberle, Director of Dakota Gold commented, "The building of Dakota Gold has been the highlight of my career. Being in a position to assemble the land package and the team of people that has so successfully executed our programs these past three years has allowed us to create exceptional value for shareholders. Our discovery of the Homestake iron-formation-hosted gold system on our Maitland Gold Project validates our thesis that the Homestake Mine is repeatable. With our focus on the nearer-term production opportunity at Richmond Hill, I am pleased that Jack Henris has joined the Company as President and COO. His heap leach experience and familiarity with the Homestake Mine are great assets to the Company as we advance to production. Dakota Gold is in a great position, poised for success. I look forward as a Board member and major shareholder to support Jack in the coming chapters of Dakota Gold's story."

Jack Henris commented, "I am excited to return to the Homestake District where I started my career. My experience in permitting and operating heap leach gold operations for Barrick and Newmont will inform Dakota Gold's strategy as we advance Richmond Hill. Working at the Homestake Mine open pit gives me the experience required to guide activities at our Maitland project area. Having worked with Jerry Aberle, I am enthused to build on the project platform that he has assembled for the Company."

Dr. Stephen O'Rourke, Co-Chair, Director, and Managing Director of Dakota Gold stated, "We are pleased to be able to strengthen our Board with the addition of Todd Kenner and Kevin Puil. In his role as CEO of RESPEC, Todd grew the company based in Rapid City, South Dakota from a revenue of $14 million in 2009 to $142 million in 2024. Todd's broad engineering experience will be invaluable as we advance Richmond Hill along its development trajectory. A native of South Dakota, Todd brings a local lens and relationships which will be important as we develop Richmond Hill and continue to advance our Maitland Gold Project and other project opportunities in the Homestake District." Dr. O'Rourke continued, "Kevin Puil has over 25 years as a portfolio manager in resource development opportunities. This is an important perspective for the Company as we seek to access funding needed to put Richmond Hill in production. Kevin's capital markets experience will reinforce the skillsets of the Board. I wish to acknowledge the support that Amy Koenig has provided to the Board over the last 3 years since joining Dakota Gold. We are pleased that Amy will join our management team as SVP Chief Legal Officer and Corporate Secretary. Amy's experience with Black Hills Corporation, South Dakota's other NYSE listed company, will be valuable as we advance Richmond Hill to production. With Todd joining our Board we have 3 directors who live in South Dakota and Dakota Gold benefits from the local perspective we bring to the Company. The addition of Jack Henris as COO and President, concurrent with our Board expansion, ensures the Company has the bandwidth and skillsets necessary to deliver on our many gold opportunities in the Homestake District.
