International Graphite Ltd Signs Collie Construction Contract for Q2 2027 Target
Construction contract signed for Collie Micronising Facility
International Graphite (ASX: IG6) has signed the key construction contract for the process building at its Collie Micronising Facility in Western Australia, with the contract signing preparing the facility for the construction phase.
The contract has been awarded to Prosser Built, a Bunbury-based construction company established more than 80 years ago with a track record across industrial and commercial projects in the south-west of Western Australia.
The Collie building permit milestone in May 2026 confirmed the Final Tender Price from Prosser Built came in within 0.1% of the 2025 FEED study budget, an early indicator of the cost discipline now being carried forward into the construction contract signing.
For investors, the signing represents a tangible de-risking step toward Australian mid-stream graphite production, shifting the facility from design into the build phase.

Why graphite micronising matters
International Graphite is establishing mid-stream graphite processing operations to supply high-spec industrial graphite for established markets seeking secure and reliable alternatives to traditional supply chains.
For investors, this positions the company within the critical minerals supply chain in trusted jurisdictions. Recent European Union initiatives, including the Critical Raw Materials Act, alongside broader G7 efforts, highlight the growing importance of industrial capacity in such regions. End-market demand spans industrial, energy storage, advanced manufacturing and defence applications.
Wogen Pacific offtake terms signed in June 2026 anchor a minimum 3,000 tonnes per year of micronised graphite sales to Asia Pacific customers, with Japan and South Korea named as primary targets, adding a commercial demand signal to the production infrastructure now entering the build phase.
Government backing and the broader IG6 platform
The project has the support of the Western Australian Government through the Collie Industrial Transition Fund and the Australian Government through the Critical Minerals Office.
The Collie facility forms part of a wider platform. Through the Alkeemia / IG6 Joint Venture at Porto Marghera, Italy, and the Collie Processing Facility in Western Australia, the company is developing a capital-efficient graphite processing platform supported by proven technologies and industry partnerships.
International Graphite also owns the Springdale Graphite Project in Western Australia, providing long-term feedstock optionality for future scaling of process operations.
The announcement was authorised for release by the Board of International Graphite Limited. Andrew Worland serves as Managing Director and Chief Executive Officer.
