The Galalar Silica Sands Project, positioned near Cape Bedford and close to Hope Vale, is poised to responsibly supply the world with high-grade silica sand, currently awaiting further development as Diatreme focuses on the flagship Northern Silica Project. 

Situated near Cape Bedford, some 20 kilometres from Hope Vale, the Galalar Silica Sands Project, while currently paused, is integral to Diatreme’s long-term vision. Diatreme is currently focused on its Northern Silica Project, with Galalar remaining a key asset subject to future development planning.

A Maiden Mineral Reserve estimate (JORC 2012) was announced in November 2021, comprising 32Mt, sufficient for an estimated 18 years of initial operations (at 1.65Mt ore processed per annum). The total JORC Mineral Resource is estimated at 75.5Mt. A pre-feasibility study was released in November 2021 that demonstrated a robust project for stakeholders.

Bulk testing results have confirmed the project’s ability to produce a world class silica sand product at 99.9% SiO2, meeting the requirements for high-end glass and solar panel manufacturing.

The GSSP continues to remain a strategic and important silica asset of the Company. However, given the NSP’s rapid advancement, its much larger scale (resource base) and close proximity to the Port of Cape Flattery clearly evidencing a clear low-cost export pathway, the development of the NSP to eventual mining activity has been given priority.
