The Cape Flattery Silica Project (CFSP) is located in the Cape Flattery area, on the eastern coastline of Cape York Peninsula, 220 km north of Cairns and 55km from Cooktown. The project is adjacent to the Cape Flattery Silica Mines mining and shipping operation owned by Mitsubishi Corporation and in close proximity to Diatreme’s other projects, facilitating potential use of shared infrastructure.

Acquired in 2024, CFSP has an estimated Ore Reserve of 47Mt with the total JORC Mineral Resource estimated at 61Mt (refer MLM’s ASX announcement dated 15 November 2023). The project and in particular its Updated DFS is under review with a view to capturing the potential synergies between it and Diatreme’s flagship NSP to facilitate shared infrastructure and reduced CAPEX.
Initial exploration drilling by Metallica Minerals in late 2019 confirmed high purity silica sand within EPM 25734. Further drilling programs were undertaken in 2020 and 2021 followed by the successful completion of a Pre-Feasibility Study in March 2022, a Definitive Feasibility Study in July 2023 and Updated Definitive Feasibility Study in November 2023.

The Updated Definitive Feasibility Study proposed extracting and processing raw sand to produce a high purity silica sand (HPSS) product of suitable quality for glassmaking in the manufacture of display panels, e-glass and in particular solar PV glass, of which over 80% of global supply is manufactured in the Asia Pacific region. Export by ship was planned from Cape Flattery to glass manufacturing companies, most likely in Asia.

The project area is bounded by the Cape Flattery coastline in the Cape Flattery Port area, which is owned and operated by Ports North, a Queensland Government owned corporation. Ports North owns the Mitsubishi leased jetty, just south of the tenement, with the jetty’s ship-loading equipment primarily owned by Mitsubishi.
