Arc Mineral Royalties Ltd. has appointed Gregory Honig to its board of directors, effective Sept. 14, 2026. The company also announces that Adam Davidson, its chief executive officer, will join the board, effective the same date.

Mr. Honig brings more than 20 years of international mining experience across executive leadership, private equity and investment banking, spanning precious and base metals, critical minerals, and industrial minerals.

His earlier experience includes business development and strategy roles at Xstrata Nickel and mining investment banking at Orion Securities. Mr. Honig holds the ICD.D designation and has extensive board experience across public and private companies, joint venture entities, and industry associations.

Mr. Davidson will continue to serve as chief executive officer alongside his board responsibilities. He was previously the founding CEO of Trident Royalties, which he led through its growth and acquisition by Deterra Royalties in 2024, before serving as Deterra's head of Americas. His earlier experience includes roles with Resource Capital Funds, BMO Capital Markets and Orica Mining Services.

Mr. Davidson, chief executive officer of Arc, commented: "We are delighted to welcome Greg to the board. His experience in mining investment, commercial negotiations and corporate strategy will be particularly valuable as we assess opportunities to grow Arc's royalty portfolio. Following our successful relisting and with Mount Henry as our foundational asset, we are focused on building a diversified portfolio of royalties and streams that delivers long-term value for shareholders. I look forward to working with Greg and the rest of the board to deliver on that strategy."

Board transition

Alongside these appointments, Robin Dow and Larry Segerstrom will step down as directors, effective Sept. 14, 2026. The company sincerely thanks Mr. Dow and Mr. Segerstrom for their service and valuable support throughout the relisting process and Arc's transition to a mineral royalty company.
