Mponeng is an ultra-deep tabular gold mine in South Africa in the Witwatersrand Basin of the Gauteng Province. [1] Previously known as Western Deep Levels No1 Shaft, the mine began operations in 1986. [2] It is one of the most substantial gold mines in the world in terms of production and magnitude, reaching over 4 kilometres (2.5 mi) below the ...

The mine is near the town of Carletonville in South Africa. At approximately 3.9 kilometers (2.4 mi) deep, it is home to the world's second deepest mining operation, rivalled only by the Mponeng Gold Mine, formerly Western Deep Levels No.1 Shaft. TauTona was temporarily closed in 2018. [2] The mine was one of the three Western Deep Levels mines.
South Africa has the world's deepest hard rock gold mine up to 3,900 metres (12,800 ft) underground. At such depths, the heat is unbearable for humans, and air conditioning is required for the safety of the workers. The first such mine to receive air conditioning was Robinson Deep, at that time the deepest mine in the world for any mineral. [40]
Model of seabed mining technology. Seabed mining, also known as Seafloor mining [1] is the recovery of minerals from the seabed by techniques of underwater mining. The concept includes mining at shallow depths on the continental shelf and deep-sea mining at greater depths associated with tectonic activity, hydrothermal vents and the abyssal plains.
The deepest active hard rock mine in North America is Kidd Mine in Canada, which mines zinc and copper in Timmins, Ontario. At the maximum depth of 9,889 feet (3,014 m) this mine is the deepest base metal mine in the world, and its low surface elevation means that the bottom of the mine is the deepest accessible non-marine point on earth.
