Keith Marshall has agreed to stand for election to Nexmetals Mining Corp.'s board of directors at the annual general meeting of shareholders to be held on May 27, 2026.

Mr. Marshall is a mining engineer with over 45 years in the sector, the last 25 years of which were in senior leadership roles. Mr. Marshall has developed a wealth of managerial and technical experience in all aspects of underground mining and operations. Mr. Marshall's last two operational roles were both with Rio Tinto, with which he worked for 22 years, as managing director of the Palabora Mining Company in South Africa and as president of the Oyu Tolgoi project in Mongolia. Mr. Marshall holds a mining engineering degree from the Royal School of Mines at Imperial College London.

Following the AGM, the board intends to appoint Mr. Marshall to the board's safety, sustainability and technical committee (SSTC), which will comprise co-chairs Warwick Morley-Jepson and Philipa Varris, along with Mr. Marshall.

The company also announces that Chris Leavy and James Gowans have advised the board that they will not be standing for re-election at the AGM.

"We are pleased that Keith has agreed to stand for election to the board," said Paul Martin, chairman of the board. "Keith will bring significant operational and technical experience to the company at a time when the Selebi and Selkirk projects are advancing from primarily an exploration focus to the predevelopment studies stage. His mining background and experience will be extremely beneficial to the company. I would also like to thank Jim and Chris for their counsel and guidance during their respective periods on the board."

The remaining seven nominees are currently members of the board, being Paul Martin, Mark Christensen, Jason LeBlanc, Mr. Morley-Jepson, Andre van Niekerk, Ms. Varris and Sean Whiteford.

Additional details regarding the nominees will be set out in the company's management information circular to be mailed to shareholders in connection with the AGM in the coming weeks. A copy of the management information circular will be available under the company's SEDAR+ profile.
