Diatreme Resources

What Diatreme Resources does

Diatreme Resources Limited (ASX:DRX) is an Australian mineral exploration and development company advancing a portfolio of silica sand and mineral sands assets. Its flagship is the Northern Silica Project (NSP) in Far North Queensland — a greenfield open-cut operation planned to produce high-purity, low-iron silica sand (SiO2 >99%, iron <120ppm) at 3-5Mtpa over a 25-year mine life, targeting solar PV and specialty glass manufacturers. The portfolio also includes the Galalar Silica Sand Project (75.5Mt JORC resource, 32Mt Ore Reserve), the recently acquired Cape Flattery Silica Project (61Mt resource, 47Mt Ore Reserve) adjacent to Mitsubishi's operating Cape Flattery mine, the Western Resource Area (91.7Mt maiden resource) as a potential NSP satellite, the Cyclone Zircon Project in Western Australia's Eucla Basin (203Mt at 2.3% heavy minerals, the largest undeveloped zircon-dominant project in the basin), and the Clermont Copper-Gold exploration project in central Queensland. Combined, the silica projects represent approximately 463.7Mt of Mineral Resources and 79.53Mt of Ore Reserves.

The company has secured key technical and regulatory milestones: NSP achieved Queensland Government 'Coordinated Project' status in January 2024 with Final Terms of Reference for the EIS issued in September 2024, and Cyclone Zircon already holds a granted Mining Lease and Ministerial Consent. Resource economics are anchored by proximity to the operational Cape Flattery Port, where a tripartite deed of access with Ports North and Cape Flattery Silica Mines enables direct transhipment to 55,000-tonne ocean-going vessels for export to Asian markets. Sibelco Asia Pacific has invested approximately A$49M cumulatively across a June 2022 strategic placement (A$13.97M) and two Cape Silica JV tranches (A$11M in December 2022, A$24M in October 2023) for a 26.8% JV interest, contributing technical expertise, joint marketing, downstream processing opportunities, and project finance assistance.

Diatreme is pre-revenue and is structured around long-term offtake agreements with Asian (predominantly Chinese) glass manufacturers. A non-binding MOU with Flat Glass Group Co Ltd was signed in July 2023 for photovoltaic-grade silica supply from NSP. The business model is project-development-driven: capital is consumed on feasibility studies, resource expansion, permitting, and stakeholder agreements (including a Cultural Heritage Management Agreement with the Dingaal Traditional Owners signed May 2024) ahead of a Final Investment Decision. Reported cash runway is less than one year as of mid-2026, making additional capital raises or project finance critical to advancing the portfolio.

Core offering

Diatreme Resources is an Australian mineral exploration and development company developing high-purity, low-iron silica sand projects (NSP, GSSP, CFSP) and a heavy minerals project (Cyclone Zircon) in Queensland and Western Australia. The company plans to produce and export silica sand with greater than 99% SiO2 purity and iron content under 120ppm to Asian solar PV and specialty glass manufacturers, alongside zircon and titanium concentrates from the Cyclone Zircon Project.

Product overview

Diatreme Resources is an Australian mineral exploration and development company with a portfolio of silica sand and mineral sands projects. The company operates a platform-plus-projects architecture consisting of five principal projects: the flagship Northern Silica Project (NSP), Galalar Silica Sand Project (GSSP), and Cape Flattery Silica Project (CFSP) for high-purity silica sand production targeting solar PV glass manufacturers; the Cyclone Zircon Project for zircon and titanium production in Western Australia; and the Clermont Copper-Gold exploration project. Combined, the silica projects hold approximately 463.7Mt of Mineral Resources and 79.53Mt of Ore Reserves. Sibelco (via Sibelco Asia Pacific) is the joint venture development partner on the silica projects portfolio.

Broad incumbents

• Tronox Holdings: Vertically integrated global mineral sands and zircon producer with titanium dioxide operations. Larger incumbent in the same heavy-minerals value chain that Diatreme's Cyclone Zircon Project targets, with overlapping customers in titanium and zircon markets.

Direct peers

• Image Resources: ASX-listed mineral sands producer (zircon, titanium, ilmenite) operating in Western Australia's Eucla Basin. Closely comparable to Diatreme's Cyclone Zircon Project on commodity mix and Western Australian mineral sands geography.
• Iluka Resources: ASX-listed major mineral sands producer (zircon, titanium, rare earths) with significant Eucla Basin presence in Western Australia. Directly comparable to Diatreme's Cyclone Zircon Project on commodity, geography and mining stage.
• Australian Silica Quartz Group: ASX-listed Australian explorer-developer focused on high-purity silica sand for solar PV, glass and other industrial applications. Direct competitor for the same Asian PV glass customer base.
• Sibelco: Global materials solutions leader and Diatreme's JV partner in the Cape Silica Joint Venture (26.8% interest). Sibelco operates a global silica sands portfolio and provides technical, marketing and downstream processing support, making it both a partner and the most directly comparable competitor in the same product category.
