The bench scale program involved purifying graphite concentrates from drilling and bulk concentrate extraction undertaken at Springdale in 2023. Various wash cycle tests returned a purity of up to 99.97% total graphitic carbon (TGC), achieving the TGC purity generally specified for lithium-ion battery anode specifications.

Further purification testwork programs on Springdale graphite concentrates and spheroidised Springdale graphite concentrates are planned.

International Graphite has been collaborating with Marubeni under a non-binding memorandum of understanding for the potential supply of spheroidised graphite from Springdale and potential financial support for International Graphite’s mine to market strategy.

Marubeni is looking to expand its access to critical minerals and is exploring avenues to secure graphite products, from concentrates to semi-processed materials, in support of Japan’s growing battery and motor vehicle manufacturing industries. Marubeni has had business interests in Australia for decades.

International Graphite Managing Director and CEO Andrew Worland said: “Partnering with a highly respected market leader like Marubeni, which is a major investor and trader in world commodity markets, gives us great confidence in our assets and development strategy.

”Japanese firms have made enormous commitments to developing battery gigafactory capacity worldwide and need new sources of graphite to meet these commitments. We offer the market a new supply of quality material, with all the benefits of Australian security and reliability.

“Marubeni is one of the strategic partners we are engaging with to tailor our future operations to best meet market demands.”

Representatives from Marubeni’s Business Development team in the Metals and Mineral Resources division recently toured International Graphite’s mining leases at Springdale, and the Collie Graphite Processing and R&D Facility.

International Graphite advises there can be no assurance that ongoing collaboration with Marubeni will lead to definitive binding agreements.

This announcement has been authorised for release by the Board of International Graphite Limited.
