Quebradona

Quebradona is a copper-gold-silver project in the department of Antioquia, Colombia. In June 2025, the Colombian government issued Resolution No. 855 of 2025 declaring a temporary renewable natural resources reserve zone over multiple municipalities including the Quebradona area, restricting mining activities for 3 years (extendable 2 years). No new environmental permits or licences may be issued while the Resolution is in force. AGA lodged an annulment and redress claim in December 2025. AGA fully impaired exploration and evaluation costs of $98m relating to the project given heightened political uncertainty.
