"I would like to congratulate Santiago on his recent appointment as Minister of Mines. Santiago brings his decades of experience and track record in the mining sector to support the incoming government of President Jose Antonio Kast. We would also like to thank Santiago for his invaluable contribution to Los Andes Copper. Santiago has been instrumental in leading the Vizcachitas project to make it the largest greenfield copper project in Chile not controlled by the majors. Under his leadership, Vizcachitas has been designed to be an example of how sustainable mining operations should be undertaken. He has brought his years of experience with majors to the development and reinforcement of relationships with the communities as well as with authorities at local, regional and national levels. We wish him the very best on his responsibilities with Chile going forward."

Santiago Montt, outgoing CEO of Los Andes, commented:

"I have been honoured to have been asked to serve my country as Minister of Mines in the incoming government of President Jose Antonio Kast. It has been a privilege working with Los Andes advancing the Vizcachitas project, one of the largest undeveloped greenfield copper projects in Chile, ensuring it is a sustainable mining project that will benefit all stakeholders. During my tenure as CEO, I have had the privilege of working alongside an exceptional Board, Chairman and Leadership Team. Together, we have achieved material progress across multiple strategic fronts. I am deeply grateful for the invaluable knowledge I have gained regarding the development of greenfield mining projects, encompassing the full business cycle from geological exploration through to stakeholder engagement. I leave with immense pride in what we have accomplished and full confidence in the leadership team's ability to carry this important project forward."
