Abstract
<div>Critical minerals are the minerals and elements essential for modern technologies, economies and national security. However, the supply chains of these minerals may be vulnerable to disruption thereby making the study of these minerals, from source to product, of primary importance. </div><div><br></div><div>The global transition to net-zero emissions is driving accelerated consumption of critical minerals, particularly driven by the increase in demand for technologies such as solar photovoltaics (PV) and semiconductors (Department of Industry, Science and Resources [DISR], 2022; 2023). In parallel, the phasing out of, for example, traditional machinery and manufacturing processes reliant on hydrocarbon resources (Ali et al., 2017; Bruce et al., 2021; International Energy Agency [IEA], 2021; 2023; Skirrow et al., 2013) is further adding to the global demand. High Purity Quartz (HPQ) forms just one of these critical minerals, and is the primary raw material for the production of High Purity Silica (HPS) and Silicon (Si) for use in products ranging from solar PVs to semiconductors. </div><div><br></div><div>The current list of minerals classified as critical is now up to 31 (Department of Industry, Science and Resources [DISR], 2022; 2023). This diversity of critical minerals is also promoting a new focus on the exploration for i) new styles of mineralisation that might host sufficient volumes of critical minerals, and ii) a re-examination of existing minerals systems knowledge in order to help mineral explorers make new discoveries to help support the increasing demand. </div><div><br></div><div>At present, the main global suppliers of HPQ are the United States, Canada, Norway, Brazil, Russia and India (Pan et al., 2022). In Australia, there has been a paucity of exploration and development of HPQ mineral deposits and, despite the potential that Australia holds for the exploration and discovery of potentially significant HPQ occurrences, Simcoa Operations Pty Ltd. (Figure 1) represents the only operator currently mining HPQ, and the only manufacturer of high purity silicon in Australia (Simcoa, 2020). </div><div><br></div><div>Australia is well-positioned to incentivise the exploration, discovery and supply of raw materials, and significantly expand onshore silicon production capacity (PricewaterhouseCoopers, 2022). Research presented here highlights the opportunity that Australia has in making a positive contribution to meeting the global demand for HPQ required for high-technology applications and the transition to a net zero economy. </div><div><br></div>Abstract presented at the 2024 Annual Geoscience Exploration Seminar (AGES)
