Company Profile
Diatreme is an emerging Australian producer of mineral and silica sands based in Brisbane. Our key projects comprise the Northern Silica Project (NSP), Galalar Silica Sand Project (GSSP) and the recently acquired Cape Flattery Silica Project (CFSP) in Far North Queensland, located near the world's largest silica sand mine at Cape Flattery. The Company’s silica sand projects have a combined Mineral Resource of 463.7 Mt and Ore Reserves of 79.53 Mt.
World class global material solutions group Sibelco (through Sibelco Asia Pacific Pty Ltd) is Diatreme’s joint venture development partner on its silica projects, via the Cape Silica Joint Venture.
Sibelco has agreed to provide Diatreme access to Sibelco’s technical and project development expertise, pursue joint product marketing and downstream onshore silica processing opportunities, as well as assistance in securing project finance.
Sibelco has completed a two-tranche investment of $35 million, taking its total project interest to 26.8%, with the balance (73.2%) held by Diatreme. In addition, Sibelco made a $13.97 million investment at the corporate level.
Both the NSP and the CFSP are significant silica development projects, which have been designated with ‘Coordinated Project’ status by the Office of the Coordinator-General in Queensland, a major milestone recognising the strategic value and importance of these important critical mineral deposits.
The Cape Flattery region has been identified by the Queensland Government as a potential silica critical mineral mining area and export hub of significance, with the purpose to focus on efficiencies in the supply chain, access to infrastructure and pathways to permitting.
The NSP is expected to produce high grade, low iron silica, with a scoping study for the project released in June 2023 indicating its potential as a valuable long-life, low cost mining operation of significant scale, with robust economics and within close proximity to existing marine infrastructure.
The Scoping Study confirmed Diatreme has a standalone independent logistics and export solution that is permittable and capable of development. However, Diatreme also continues to explore shared facilities and infrastructure solutions to provide alternative solutions and potential other benefits.
Diatreme also has two other projects, the Cyclone Zircon Project in Western Australia, one of a handful of major zircon-rich discoveries of the past decade in Australia; and the Clermont Copper-Gold Project (DRX:100%), a copper/gold and graphite exploration project, in a proven mining jurisdiction in central Queensland.
Diatreme has a highly experienced Board and management, with expertise across all stages of project exploration, mine development and project financing together with strong government, regulatory and community engagement credentials.
Diatreme’s silica resources will contribute to global decarbonisation by providing the necessary high-grade silica for use in the solar photovoltaic industry. The Company has a strong focus on ESG, working closely with its local communities, traditional owners and all other key stakeholders to ensure the long-term sustainability of our operations, including health, safety and environmental stewardship of the regions and in communities in which we operate.
