The sixth chromite seam in the Lower Group (LG6) is an important source of chromite ore and is the ore body extracted at the mine. In the Eastern Lobe, in the vicinity of the mine, the strike is nearly north-south, with a dip of approximately 10 degrees towards the west. The average thickness of the LG6 seam is about 1.86 metres in the mine area.
Small ores can be found scattered around on the surface of the ground. These are samples of what ore veins are located within 35 blocks underneath the soil, so they're somewhat important.
