AngloGold Ashantis Mponeng gold mine, located south-west of Johannesburg in South Africa, is currently the deepest mine in the world. The operating depth at Mponeng mine ranged from between 2.4km to more than 3.9km below the surface by the end of 2012. Ongoing expansions have resulted in deeper digging at Mponeng, pushing the record to beyond the f...
TauTona, AngloGold Ashantis gold mine in the West Wits region of South Africa, ranks as the second deepest mine in the world. Although mining at TauTona currently takes place at depths ranging from between 1.85km to 3.45km, its mining depth was extended to 3.9km underground with the addition of a secondary shaft in 2008. The mine primarily exploits...
TauTona mining operations began in 1962 with the construction of 800km of tunnels. The mine is currently operated with three shafts.
TauTonas mine life is expected to end in 2015. It produced 189,000oz of gold in 2012. The estimated ore reserve stood at 1.713Moz as of December 2012.
The mining method at Savuka was recently converted from longwall to sequential grid mining. Savuka shares a common processing plant with the TauTona mine.
The shafts and infrastructure at Savuka were damaged by a seismic event in 2008. The mining operations were, however, completely restored in 2011.
The Driefontein mine operation could be traced back to 1952. The mine consists of eight producing shaft systems extracting ore from three reefs, namely Ventersdorp Contact Reef (VCR), Carbon Leader Reef (CLR) and the Middelvlei Reef. Driefontein uses a combination of longwall and scattered mining methods. The first production from the Creighton ope...
The Kusasalethu gold mine operated by Harmony is located 75km west of Johannesburg, on the West Wits Line near Carletonville, Gauteng, in South Africa. It is currently the fifth deepest mine in the world as it exploits the Ventersdorp Contact Reef (VCR) up to a depth of 3,276m below the surface.
The Kusasalethu mine contained a proven reserve of 2.7Moz of gold grading 0.208oz/t and a probable reserve of 4.4Moz of gold grading 0.172oz/t as of December 2012. The mine produced 181,105oz of gold grading 0.137oz/t in 2012. A total of 5,237 employees and 979 contractors were engaged in the mining operation during the same year.
The mine exploits the Vaal Reef (VR) through three mining layers, namely the Top, Middle and Lower Mines. Moab Khotsong employs a scattered mining method with an integrated backfill support system.
The managed mineral reserve at South Deep as of December 2012 was estimated to be 39.1Moz. The mine produced 270,000oz of gold in 2012. It is undergoing a major development project to increase its annual production to 700,000oz by 2016. The mine life of South Deep is expected to be extended up to 2092.
The proven and probable reserve of Great Noligwa as of December 2012 stood at 390,000oz of gold grading 8.75g/t. The mine produced 84,000oz of gold in 2012 employing 2,985 permanent employees and 78 contractors.
Creighton, an underground nickel mine located in the City of Greater Sudbury, Ontario, Canada, is the tenth deepest mine in the world. It is also the worlds deepest nickel mine, with its mining depth extending up to 2.5km. The mine is owned and operated by Vale. The mine was discovered in 1991.
The mine produced 797,000t of ore grading 1.80% copper and 1.84% nickel in 2012. Exploration drilling carried out at Creighton in 2007 confirmed mineralisation at depth. The Creighton Deep exploration Project is believed to have almost doubled the proven and probable reserve to 32Mt grading 1.9% to 2.2% nickel and 2% to 2.3% copper.
Bear and Bull markets have an impact on the daily buying and selling of Gold. In both cases, there are several factors influencing how gold would do in a sub $1300 per ounce situation.
Oct 20, 2023 · Underneath — and virtually unseeable from ground level — at just 9 inches (23 centimeters) in diameter, is the world's deepest man-made hole. The Kola Superdeep Borehole runs about 40,230 feet (12,262 meters) or 7.6 miles (12.2 kilometers) into Earth's surface.
It is one of the most substantial gold mine mines in world in terms of production and magnitude, reaching over 4 kilometres (2.5 mi) below the surface. [3] [4] At this depth Mponeng takes the title of world's deepest mine from ground level, with aims to deepen the mine beyond 4km in order to reach more reserves.
