DAVID HARQUAIL AND DANIEL MYERSON TO JOIN ERRINGTON METALS AS STRATEGIC ADVISORS

Errington Metals Corp. has appointed David Harquail and Daniel Myerson as strategic advisers to the company.

"Having two incredibly accomplished mining and company-building leaders choose to participate in and contribute to the growth of Errington Metals is a great honour and a testament to both the geological opportunity that remains in Sudbury and the strength of the team we are assembling to advance the project," stated Matthew Gollat, president and chief executive officer of Errington Metals. "Canada's mineral endowment is among the best in the world, and we believe the Sudbury basin continues to offer exceptional potential for new discoveries when combined with disciplined exploration and experienced leadership."

Mr. Harquail is chair of the board of Franco-Nevada Corp. and is expected to transition to chair emeritus in May. He previously served as chief executive officer for more than 13 years following the company's public listing in 2007.

Mr. Harquail has a long-standing connection to Sudbury and Laurentian University, where he served as governor from 2022 to 2025 and is a major benefactor of the School of Earth Sciences, including the Mineral Exploration Research Centre (MERC) and the Harquail School of Earth Sciences. His philanthropic support has played a meaningful role in advancing mineral exploration education and research in the Sudbury basin.

He is a director of the Bank of Montreal and has held senior executive and board roles across numerous public companies. Mr. Harquail holds a BASc in geological engineering from the University of Toronto, an MBA from McGill University, is a registered professional engineer in Ontario and was inducted into the Canadian Mining Hall of Fame in 2026.

Mr. Myerson is a disciplined mining entrepreneur and company builder with a strong record of creating shareholder value through discovery, development, financing, operations and strategic leadership. He currently serves as deputy chairman of Eldorado Gold and was previously chief executive officer and executive chairman of Foran Mining Corp. until its acquisition in 2026.

At Foran, he led the company's transformation into one of the sector's most respected growth stories, expanding its resource base whilst making new discoveries and establishing a world-class mineral district through exploration success, advancing key permits and environmental approvals, and securing value accretive financing to move the project from discovery toward production. He also positioned the company as a leader in sustainable mining through its commitment to carbon neutrality and economic renewable energy supply, environmental stewardship, and community partnership.

"Errington's project stands out for its high-grade nature, meaningful scale potential and premier location in Canada, where strong infrastructure, clear permitting frameworks and constructive community engagement and a forward-thinking government support responsible precious metals and critical minerals mine development -- this is everything you want in establishing a world-class district," stated Mr. Myerson. "The company is pursuing a well-known and proven path -- advancing a high-quality asset with discipline, building long-term stakeholder trust and creating value through each stage of development. I believe Errington is exceptionally well positioned to unlock significant value for shareholders."
