Exploration and Drilling
Conventional and unconventional boreholes
are drilled by pitting and trenching within the mining leasehold areas.
They are drilled on a grid pattern of 200 x 200 meters to locate the
ore body. The grid maybe tightened for a detailed assessment and quality
control. Bore holes are made to a minimum of 60 meters but if the ore
body persists, they will be drilled through the entire thickness. The
core of the bore hole is systematically stored in wooden boxes, logged
and sampled for every 1.5meters and sent for detailed chemical analysis.
The Mining operations are done by the open
cast methods. Rippers and Dozers are used to loosen the hard laterite
cover which is treated as reject. The loosened reject material is then
loaded using hydraulic excavators and transported using tipper trucks
to the waste/rejection dump which are maintained outside the mineralized
zone. Excavators and trucks are then used to mine the crude ore and
transport it to the processing plants. If the ore body is situated below
the ground water level, pumps are used to lower the water table.
