New data has revealed the potential for high-purity silica mining in New South Wales, paving the way for the development of the critical resource in the state.
Launched by Minister for Natural Resources Courtney Houssos at the WB Clarke Geoscience Centre, the findings reveal significant exploration opportunities across the Broken Hill, New England and Lachlan regions.
Of the 400 samples taken across the state, 50 contained high purity silica exceeding 99.8 per cent purity, with the highest recorded value reaching 99.6 per cent.
Minister for Natural Resources Courtney Houssos said: “NSW is rich in the critical minerals the world needs to power a clean energy future and support advanced technologies.”
High-purity silica is an essential ingredient in high-tech and clean energy products. It is used to produce silicon for products such as semiconductors, solar panels and specialty optical equipment.
The study identified silica in a wide number of different forms across the state. However, the state still remains unexplored for high-purity silica, and renewed exploration could locate new opportunities with the potential to supply global markets.
Chief Geoscientist and Head of the Geological Survey of NSW Dr Phil Blevin said: “Access to new and historical materials gives NSW a head start in identifying critical mineral opportunities across the state.”
With growing global demand for silicon in clean energy and digital technologies, New South Wales is well-positioned to contribute to secure and sustainable supply chains for critical minerals.
Houssos said the state government will work with the industry to provide more opportunities for investment and innovation while delivering the government’s Critical Minerals and High-Tech Metals Strategy.
“It’s initiatives like these that provide precompetitive data and de-risk exploration, which are instrumental in making NSW a great place to invest,” Houssos said.
“This is another step towards delivering the Minns Labor Government’s Critical Minerals and High-Tech Metals Strategy, ensuring that NSW remains a global leader in sustainable exploration and mineral processing.”
