Renascor Resources’ Siviour graphite project is located on the Eyre Peninsula, South Australia.
With graphite demand outstripping supply, the market is bracing for a 777,000-tonne per year deficit by 2030. But movement in the mining sector – both traditional and innovative – may be set to change this.
One of the key raw materials in the green energy transition is graphite, but while Australia is a key producer of other battery metals such as lithium, nickel and manganese, there are no active Australian graphite mining operations.
Graphite is used as an input for anodes – one of two electrodes that make up a lithium-ion battery, with cathodes – made up of metals such as lithium, nickel and cobalt – the other electrode.
By 2030, demand for graphite is expected to hit four million tonnes (Mt) per year, roughly 75 per cent of which is for the lithium-ion battery market. Currently, the bulk majority of graphite comes from China.
The highest profile Australian-focused company in this sphere is Renascor Resources, which owns the Siviour battery anode material project in SA.
Siviour holds the second largest graphite reserve in the world, and the largest outside of Africa.
As recently as last week, the Renascor increased Siviour’s mineral resource by 25 per cent to an impressive 123.6Mt at 6.9 per cent total graphitic carbon (TGC), for 8.5Mt of contained graphite.
The company predicts the mine, when operational, to produce up to 150,000 tonnes per year for a 40-year life of mine.
“As the demand for graphite grows, long-life, high quality sources of new supply like Siviour are becoming increasingly important to the developing lithium-ion battery supply chain,” Renascor managing director David Christensen said.
In July this year, the company signed a Memorandum of Understanding with Mitsubishi Checmical Corporation for the potential sale of its graphite products from Siviour to the Japanese giant.
Founded in 2018, ASX-listed International Graphite was built on the premise that the industry would need more downstream processing capacity outside of China.
The company is developing a mine-to-market business model, whereby raw materials would be mined from its Springdale project in WA and fed into a downstream processing plant in the emerging renewable energy hub of Collie.
International Graphite similarly announced a significant increase to its graphite deposit at Springdale, which is the second largest in Australia behind Siviour.
The deposit grew from 15.3Mt to 49.3Mt at 6.5 per cent TCG.
Despite the 27 per cent increase, International Graphite managing director Andrew Worland said the company had only scratched the surface at Springdale.
“So far, exploration has been limited to approximately 10 per cent of the Springdale tenement areas. More than 80 per cent of the aeromagnetic anomalies on a portion of our tenure has yet to be tested,” Worland said.
Outside of Australia, interesting developments have been made.
New Zealand-based battery material company CarbonSpace recently secured an $18 million investment from a number of partners to commercialise production of what it calls ‘biographite’.
Biographite is produced from forestry and timber industry by-products, meaning a significant reduction in carbon emissions.
“Biographite has a carbon negative footprint, saving up to 30 tonnes of CO2 emissions per tonne of material compared to synthetic or mined graphite,” the company said.
“This investment represents a strong statement of support for sustainable sourcing of battery materials for global decarbonisation. With these partnerships, CarbonScape is another step closer to bringing biographite to market on a commercial scale.”
