Golden Minerals Company

Golden Minerals Company announced that Pablo Castanos has resigned as President and CEO, effective September 30, 2026, to pursue another opportunity, though he will remain a director. The Board has appointed David Watkins, a director since 2009, as the new President and CEO, effective the same date. Additionally, the company noted that its partner in the Sarita Este and Desierto projects in Argentina, Cascadero Copper Corporation, has agreed to sell its interests in those properties to Lumina Copper Corporation, a wholly-owned affiliate of First Quantum Minerals. Golden Minerals is planning a first-stage drill program to test potentially deep mineralization similar to that at First Quantum's Taca Taca project, with details expected later in September.
