International Graphite Limited (ASX: IG6) is making rapid progress on feasibility studies to advance development of the Company’s integrated graphite processing operations in Western Australia.
At the 100% owned Springdale Graphite Project (Springdale), site of the Company’s planned graphite mine, a ten hole diamond drilling program is currently underway. Drilling results will provide important data for geotechnical studies required for mine planning, waste characterisation, and resource classification, as well as additional sample material for further metallurgical testwork which will be used to inform process design criteria for the graphite concentrator.
Managing Director and CEO Andrew Worland said global pressures on both Lithium-ion battery manufacturers and industrial graphite end users, including geopolitical pressures, were continuing to build demand for graphite from markets such as Australia.
“The once in a generation growth in battery and vehicle manufacturing capacity, that North America, Europe and Asia have committed to developing, depend on supply from mines like Springdale that will offer unparallelled supply chain certainty,” Mr Worland said.
Battery anode processing testwork on Springdale concentrates is also continuing. The comprehensive program, being undertaken at a number of specialised overseas testing facilities, includes spheroidisation optimisation, leach purification option evaluations, production of both purified and unpurified spherical graphite samples for third party evaluation and coating options, and further electrochemical studies.
Flora and fauna reports for Springdale from seasonal surveys completed in 2022 and 2023 confirm that the mine would have little impact on natural vegetation or wildlife. Additional studies are underway to support environmental approvals and permitting, including hydrological and tailings storage assessments.
At Collie, the centre of the Company’s downstream processing operations, various flake product sizes have been successfully produced using the Micronising Qualification Plant commissioned earlier this year. The products meet a range of technical specifications for end users. Critically, flake size distributions produced are suitable for both advanced battery anode materials and other industrial applications. Product samples are now planned to be Figure 1 shows the laser particle size distributions of micronised graphite sample products produced at the company’s Micronising Qualification Plant in Collie.

Investor Insight
International Graphite’s mine-to-market strategy, leveraging its compelling graphite resource, places the company in a strategic position to become an important player in the development and expansion of Western Australia’s battery supply chain.
Overview
International Graphite (ASX:IG6) is a front-runner in the global graphite industry and is aiming to be one of the first new graphite producers.
The company’s vision for a complete mine-to-market supply chain in Western Australia leverages the state’s global reputation as a secure, reliable and technically advanced resource jurisdiction.
Primary focus is the production of active anode materials for lithium-ion batteries to address growing global demand and the forecast shortage looming for allied markets, particularly the US, Europe, Korea and Japan.
Since listing on the ASX in 2022, the company has made rapid headway in the development of two major assets – a planned graphite mine at Springdale and downstream processing facilities at Collie.
The company has been awarded AU$13.2 million in grants from Australian state and commonwealth governments in recognition of its significance to the development of Australia’s sovereign battery minerals capability.
International Graphite also secured a $4.5 million grant funding from the Western Australian Government to construct the first purpose-built commercial graphite micronising plant. About $2 million will be applied towards the ~3,000 tpa micronising facility to be built in Collie at an estimated capital cost of $4 million and the remaining $2.5 million will be applied to expand the facility and at least double capacity (Stage 2).
In addition, the Western Australian government has further earmarked AU$4 million from the Investment Attraction Fund's New Energies Industries Funding Stream to support the progression of the Springdale graphite project and the development of the Collie Processing Facility.
Market demand
Market attention worldwide is swinging to graphite which is essential for global decarbonization and fast becoming one of the most politically contested of all the critical battery minerals. The graphite market is projected to reach US$24.21 billion by 2031 driven by a CAGR of 5.20 percent.
Graphite is flexible, conductive, heat and corrosion resistant. For decades it has been used to manufacture everything from ceramics and lubricants to plastics and steel.
It is also a major ingredient in batteries of all kinds, making up 95 percent of the active anode in lithium-ion batteries which are the gold standard for electric vehicles, renewable energy storage and advanced medical, defense and aerospace devices.
Of all the components in a lithium-ion battery, the biggest volume is in graphite. It can take 50 to 100 kilograms of graphite to make a single EV battery – up to 10 times more graphite than lithium.
Currently, China supplies over 80 percent of the world’s processed graphite, so its decision to restrict exports to western customers came as a shock in late 2023.
Western nations are scrambling to find alternative supplies to meet existing commitments – and new supplies to meet the shortage of battery materials forecast in the next five years.
With limited graphite sources of its own, and limited prospects in the near term, the US is leading the way, closely followed by Europe, offering unprecedented incentives to fast-track graphite supply from reliable domestic and allied sources.
Company Highlights
- International Graphite (ASX:IG6) is developing a sovereign mine-to-market graphite supply chain in Western Australia, incorporating a graphite mine at Springdale, near Ravensthorpe on the south-coast, and downstream processing facilities in Collie, 200 km south of Perth.
- Primary focus is the production of active anode materials for lithium-ion batteries to address growing demand and a forecast shortage in allied markets, particularly the US, Europe, Korea and Japan.

Key Projects
Springdale Graphite Project
International Graphite owns 100 percent of the Springdale graphite project in the established mining centre of Hopetoun/Ravensthorpe, on the south coast of Western Australia.
Springdale is one of the largest graphite deposits in Australia and was named Discovery of the Year in the respected 2023 Prospect Awards.
Following an extensive drilling campaign in 2022-23, the resource estimate increased by more than 240 percent to 49.3 Mt @ 6.5 percent total graphitic content (TGC). This is expected to grow in the future as only 10 percent of the tenement area and 20 percent of initial geological targets have been drilled to date.
Springdale is the site of the company’s planned graphite mine which will provide a consistent and reliable feed of graphite concentrates for downstream processing and give the company full control of its supply chain. A scoping study, released in January 2024, showed the planned open pit operation would be globally cost competitive with a long, multi-decade mine life.
The planned mine is on cleared farmland, with easy access to established roads and infrastructure. Permitting activities are well underway and two mining leases have been granted. The regional community relies heavily on the mining sector and has applauded moves to establish a new operation in their area.
Metallurgical testwork on Springdale concentrates, completed by specialist testing laboratories in Australia and overseas, shows the high-grade, fine flake Springdale ore is ideally suited for the production of battery anode material. Bench scale micronising, spheroidising and purification testwork on graphite concentrates were undertaken by industry specialists ProGraphite GmbH and produced outstanding results. The tests produced two spherical graphite products – SpG11 and SpG18 – with a yield of up to 76 percent. Purification testwork reached 99.99 percent graphite purity – well above the usual specification for battery anode material at 99.97 percent.
International Graphite’s vision for a complete mine-to-market business is designed to achieve maximum value from its Springdale natural graphite resource and is closely aligned with the Australian government's critical minerals strategy and the Western Australian government's vision to establish new world-class industries in Collie.
Collie R&D and Processing Facility
International Graphite’s Collie R&D and Process Facility is a first for Australia and a key link in the company’s mine-to-market strategy.
Backed by an ISO 9001 quality assurance certificate, the Collie facility is home to pilot scale graphite micronizing and spheroidizing equipment, thermal purification equipment, and a qualification-scale micronizing plant that is currently producing sample products for assessment by potential customers in the industrial manufacturing and battery markets.
As well as being widely used in industrial products such as lubricants, plastics and polymers, micronized graphite is a critical conductive additive in battery cathodes. It is also the first stage in the production of active anode material for lithium-ion batteries.
International Graphite plans to expand micronizing at Collie to commercial scale with construction scheduled in 2025. At the same time, it is progressing plans for a separate advanced battery anode material manufacturing facility. The plant design will be tailored to process Springdale graphite concentrates.
Located 450 km by road from Springdale, and close to major export ports, the regional township of Collie is the centre of Western Australia’s electricity generating infrastructure.
