The TauTona (''great lion'' in Setswana) Gold Mine, located in the West Wits area of South Africa, is the second deepest pit in the world. TauTona''s operational depth reaches up to below the surface, and it has 800 km of tunnels and three shafts.
Open cast Mineral Resources are quoted as insitu tonnages and Mineral Reserves are tonnages falling within an economic pitshell. The evaluation method is generally Ordinary Kriging with mining block sizes ranging from 10 x 10m to 100 x 100m to 250 x 250m in the plan blocks vary in thickness from to Inverse Distance method is used in some instances and with similar block
Openpit mining commenced at Palabora in 1964 and ended in 2002 when the pit reached its final economic depth. The development of an underground mine to work the ore remaining below the pit bottom began during the final years of openpit production, at a cost of 465m, with the prospect of a further 20 years'' life in the underground operation. The integrated copperproduction complex has a

Openpit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of openpit mining. The removal of this material is known as stripping. The strippingpit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit
