Mr. Chambers will drive global investor engagement, leveraging his strong geological, investor relations and business development background. Over the past 12 years, Mr. Chambers has worked across a number of commodities, focusing exclusively on Latin America. Mr. Shimamoto joins Solaris as vice-president, finance, where he will lead financial strategy (which includes external and internal reporting and financial modelling) and oversee procurement and contract management.

Matthew Rowlinson, president and chief executive officer, commented: "I am delighted to welcome Richard, Patrick and Ignacio to the management team and look forward to working closely with them to execute our strategy of maximizing returns for all stakeholders. I would also like to thank the outgoing Solaris team for their service to the company and for playing a pivotal role in establishing the Warintza project as a world-class multigenerational copper deposit. Two thousand twenty-five is an exciting year for the company as the project continues derisking activities and I look forward to keeping the market updated on the value-accretive progress."
