Perseus Mining Announces High Grade Drill Results at Edikan Mine Site
Perseus Mining Limited has recently provided details of further high-grade gold intercepts during recent drilling on the Bokitsi South Deposit at its Edikan Gold Mine (EGM) in Ghana, West Africa. The Bokitsi drill program included 37 RC drill holes totaling 2,973 meters. Aside from the three holes that were diamond core tailed due to the presence of water, the predominantly RC drilling program was conducted with dry samples.
This drilling program targeted areas containing Inferred Mineral Resources at Bokitsi South. The southern extent of the lode was also tested. The drill results will now be incorporated into a revised estimation of the Mineral Resources at Bokitsi South to be published early in the September 2014 Quarter. A maiden Mineral Reserve estimate for the Bokitsi South deposit based on the updated Mineral Resource data is expected to be released late in the September 2014 Quarter.
The Bokitsi sediment shear hosted mineralized zone extends along the western flank of the Fetish deposit to 1.5 kilometers to the south. Mineralization is contained in a 5 to 25 meter-wide shear zone in volcaniclastic sediments with silica-sericite alteration, quartz veining and 1 to 3 percent pyrite plus arsenopyrite. While the granite-hosted deposits at Edikan tend to be low-grade and wide, the sediment shear-hosted deposits are narrower and of a significantly higher grade.
Two discrete deposits have been delineated on the trend, including Bokitsi North, which is located immediately west of the Fetish deposit, and Bokitsi South. Oxide ore was mined from both deposits in the 1990’s, with the Bokitsi South lode exploited by Ashanti Goldfields.
Metallurgical test work conducted on the Bokitsi South gold mineralized material indicates that it is amenable to processing through the EGM circuit at marginally lower recoveries than the Edikan granite orebodies.
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.
