This list of deepest mines includes operational and non-operational mines that are at least 2,224 m (7,297 ft), which is the depth of Krubera Cave, the deepest known natural cave in the world. The depth measurements in this list represent the difference in elevation from the entrance of the mine to the deepest excavated point.
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 ...
Kidd is the deepest base metal mine in the world. The bottom of N° 4 shaft at Kidd Creek Mine D is 3,014.3 metres (9,889 ft) below the surface, [ 13 ] 2,735 metres (8,973 ft) below sea level , the deepest accessible non-marine point on Earth.
In 1915, the Morro Velho mine reached a vertical depth of 5,824 feet (1,775 m), which made it the deepest mine in the world. [ 2 ] [ 3 ] The miners continued going deeper, and the mine kept the title of world's deepest until 1928, when the Village Deep mine in South Africa reached a vertical depth of 8,000 feet (2,400 m), exceeding the depth of ...
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.

The mine, with a depth of 1,600 metres (5,200 ft) in 2019, is Australia's deepest underground gold mine and the deepest trucking mine in the world, with a proposed depth of 2,300 metres (7,500 ft) by 2031. From its discovery to 2019, the mine produced 5.5 million troy ounces (170 t) of gold, at a 2019 equivalent value of A$10 billion. [5]
In the beginning, surface mining was used, but the mine has been mined with the sublevel caving mining method since the 1960s. In 1985 reserves for the Kiruna Mine were 1,800 million tonnes grading 60–65% iron and 0.2% phosphorus. [26] [1] As of 2018 the Kiruna Mine had Proven and Probable Reserves of 683 million tonnes grading 43.8% iron. [27]
