Silica – a critical mineral for a sustainable future
Company Overview
Who is Silica Resources Australia?
Silica Resources Australia (SRA) is a public, unlisted, critical minerals company that is fully independent and 100% Australian owned. SRA was formed specifically to be the owner of the Mourilyan Silica Sands Project.
Silica Resources Australia vision:
Our vision is to responsibly mine and manufacture Australian critical minerals to power the global energy transition and drive technological innovation. We aim to create shared value to all parties through respectful and constructive engagement with our stakeholders.
Why the Mourilyan Silica Sands Project:
SRA was established in November 2021 to develop the Mourilyan Silica Sands Project. SRA currently owns 100% of the shares of Mourilyan Silica Resources which holds all the assets that comprise the Mourilyan Silica Sands Project.
Stage 1 of the project has had a mining lease in place since 2003. The sand resource on the Stage 1 land has been used for building and construction sand for over four decades.
The Mourilyan Silica Sands Project is an important investment in the future of Queensland and Australia. The rare naturally occurring high-purity silica sand found in the Mourilyan deposit will provide a stable, sustainable supply of high-quality silica to drive the energy transition from traditional fossil fuels to renewable sources and for technological and defence industries. Mourilyan’s silica, (which can potentially form silicon and is designated a critical mineral by the Australian Government), has the power to position Australia as a leading global supplier of sustainably produced silica. This will contribute to securing national energy supply chains and support the development of a made-in-Australia solar power industry. It will also provide the silica to keep up with our technological and defence industry needs.
The unique qualities of the Mourilyan silica sand make it ideal for use in renewable solar panels and other future-facing technologies such as high-end glass and potentially silicon wafers for microchips and semiconductors. The low-iron and low-chromite content, and the fine grain size of the glass sand will enable the production of low carbon-intensity glass products needed to create a sustainable future.
On 21 October 2025, Minister for Finance, Trade, Employment and Training, the Honourable Ros Bates announced a $30 million investment by Queensland Investment Corporation in Silica Resources Australia.
