About the Company  

ACG Metals is a company with a vision to build a global, high-margin, copper-focused producer with safe, efficient, and sustainable operations.

In September 2024, ACG successfully completed the acquisition of the Gediktepe Mine. Since then, the Company has transformed the operation from a gold and silver producer into a copper producer, achieving first copper and zinc concentrate production in August 2026. Gediktepe is targeting annual steady-state copper equivalent production of 20-25kt.

ACG's team has extensive M&A experience built through decades spent at blue-chip multinationals in the sector. The team brings a significant network as well as a commitment to ESG principles and strong corporate governance.
