Vermiculite is mined from a separate pit, located adjacent to the copper pit. The mining operation involves blasting the ore in the pit, which is approximately 50 metres deep, loading the ore onto trucks, and transporting it to the surface, where it is then sent to the nearby Vermiculite Plant. The pit is a lot shallower than the open copper pit.
