[SLIDESHOW] The Deepest Underground Mines in the World
South Africa is home to some of the deepest underground mines in the world. From the Mponeng gold mine to the Savuka mine, we expose some of the deepest, darkest underground mines the industry has to offer.
TauTona Gold Mine
Located in the West Wits region of South Africa, the TauTona ranks as the world’s second deepest underground mine in the world. Owned and operated by AngloGold Ashanti, the mine goes miles under the earth’s surface at depths ranging from 1.14 to 2.14 miles. In 2008, the company added a secondary shaft that reaches almost two and a half miles underground.
Mponeng Gold Mine
The title for the deepest underground mine belongs to Mponeng. As the deepest man made hole on earth, the depth of Mponeng is almost mystical. If you measured from the bottom of the mine to the surface you could stack 10 Empire State Buildings on top of each other. Mponeng is another underground mine owned and operated by AngloGold Ashanti.
Savuka Gold Mine
The Savuka Gold Mine, situated in Gauteng, South Africa, is one of the deepest underground mines in the world. The site, which has been rocked by occasional seismic activities, is currently being restored and structured to prevent further troubles. In 2012, the mine produced 37,000 ounces of gold. Owner and operator of the site, AngloGold Ashanti, is contemplating incorporating Savuka into the neighboring TauTona for accessing the remaining resources.
British Lithium Pressured Due To Calls for Electric Cars
The British demand for lithium is set to reach 75,000 tonnes by 2035 as the government works towards their ban on the sale of high-polluting diesel and petrol vehicles within the UK. This comes as automakers worldwide continue to insist on the benefits electric vehicles will have on slowing the rate of climate change.
It is estimated that the UK will require 50,000-60,000 MT of lithium carbonate a year by 2035 for battery production to satisfy government needs. This is assuming production remains at 1.2 million vehicles per year, and the amount of lithium required does not increase.
British Lithium, which hopes to begin constructing a quarry to produce 20,000 MT of lithium carbonate a year in a $400 million investment, are not without competitors, both within the UK and abroad.
Competition For Lithium Rises In Europe
After only five years after its initial launch, Cornish Lithium is setting its sights on becoming a UK powerhouse in mining lithium, aiming to begin commercial production in under four years. Jeremy Wrathall, a former investment banker and current managing director of Cornish Lithium, had the future in mind when founding the company.
“In 2016, I started to think about the electric vehicle revolution and what that would mean for metal demand, and I started to think about lithium,” he said in an interview with AFP. “A friend of mine mentioned lithium being identified in Cornwall, and I just wondered if that was a sort of unrecognised thing in the UK.”
Lithium was first discovered in Cornwall around 1864 and has not been mined again since 1914 when it was produced as an ingredient in fireworks. Now, however, Cornish Lithium is reportedly in the testing stage to see if the metal can be produced commercially to meet the growing demand required for the electric car sector.
Despite Cornwall’s close historic ties to mining lithium, Wrathall insists that the project is purely commercial.
Cornish Mining Revival For Lithium Production
“It’s not a mission that drives me to the point of being emotional or romantic,” he says. “It’s vitally important that we do get this technology otherwise Europe has got no lithium supply.”
The European Commission has also stated their goal to end the sale of new petrol and diesel cars by 2035 to aid the environment. That being said, the majority of lithium extraction currently relies on power provided by environmentally damaging fossil fuels─a slight contradiction.
Alex Keynes, from the Brussels-based lobby group Transport & Environment, is adamant that mining for lithium should be done sustainably.
“Our view is that medium-to-long term, the majority of materials including lithium should come from efficient and clean recycling.
“Europe from a strategic point of view should be looking at securing its own supply of lithium.”
Despite growing competition from abroad, British Lithium Chairman, Roderick Smith, continues to place importance on the mining of lithium within the UK.
“Imagine what the UK economy would look like if we lost our automotive industry,” Smith says. “The stakes are high for the UK.”
Smith expects the UK to compete with other European countries to secure a lithium battery plant in the near future.
