Overview

Chromite ore was extracted from openpit mines reaching depths of approximately 200 meters until 2005. In 2003, underground mining began.
The underground mine is accessible either via an incline ramp or a mine shaft. Ore extraction started at level 500, from which the process proceeds upwards towards the bottom of the openpit. Fully excavated primary stopes are filled with waste rock. From each stope, the ore is carried to an underground crushin
