The deepest mines in the world are the TauTona (Western Deep Levels) and Savuka gold mines in the Witwatersrand region of South Africa, which are currently working at depths exceeding 3,900 m (12,800 ft). There are plans to extend Mponeng mine, a sister mine to TauTona, down to 4,500 m (14,800 ft) in the coming years. [citation needed]

The sublevel stoping mining method is commonly used in largescale mining. It is a versatile and productive method that is primarily used for large ore bodies with a steep dip, regular shape and defined ore boundaries. Learn more below.
Specific examples of cave mining techniques include block caving, panel caving, inclineddrawpoint caving, cut and fill mining, shrinkage stopping, sublevel longhole mining, roomandpillar mining and front caving. Cave mining is typically used to mine copper, coppergold, iron and molybdenum.
This mine is an open pit mine producing 5,000 tonnes ore and 5,000 tonnes waste per day. Rock characteristics for both ore and waste are typical of those of granite or porphyritic material. Operating conditions, wage scales, and unit prices are typical for western mining operations. All costs listed are in 2012 US.
