Mine access to the open-pits is via a single haul road developed as part of the starter pit and the final pit and extending from surface to a depth of 145m below surface. The open-pit is designed with the following parameters: 20m wide ramps with a gradient of 10% and overall slope angles ranging from 45 to 58. Other final design aspects are: bench heights of 15m; batter angles of 75; and berm widths of 8m.Mining methods comprise standard drill-blast- load-haul with a total material moved capacity of 9.5Mtpa. Mining occurs by drilling and blasting 5m high sub-benches with 120mm to 200mm blast holes. Hydraulic excavators with 8.4m3 bucket capacities load blasted ore and 10.0m3 bucket capacities load waste into 80t rear-dump haul trucks. Additional service equipment comprise graders, tracked dozers, water trucks and general service vehicles

With look-ahead technology unexpected features and events could be detected and avoided or additional engineering measures put in place to prevent injuries and damage to equipment. The economic benefits of anticipating the narrowing or widening of the mined strata or other changes in the geologic nature of the orebody would also be substantial

In 1934 the first modern mining started with the extraction of apatite for use as a fertiliser. In 1946 a well known South African geologist Dr. Hans Merensky started investigating Loolekop and found economically viable deposits of apatite in the foskorite rock. In the early 1950s a very large low grade copper sulfide ore body was discovered
