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.

Development of the mine itself is different for an open pit to an underground mine and will require different experience and equipment. Porphyry deposits are often large and many of the deposits are near the surface and mined as open pits with large mining equipment; however, at depth some may have suitable characteristics to convert to large ...
The list of commodities is extensive, although the relative proportions mined underground and on the surface vary from mineral to mineral. Massive tonnages of hard coal and lignite are also produced from surface mines, although the terminology used – open cast or open cut, rather than open-pit – indicates that the technology and …
