The importance of critical minerals and the need to expand and diversify critical mineral supply chains has been endorsed by the Federal governments of Australia, Canada, and the United States. The geoscience organizations of Geoscience Australia, the Geological Survey of Canada and the U.S. Geological Survey have created the Critical Minerals Mapping Initiative to build a diversified critical minerals industry in Australia, Canada, and the United States by developing a better understanding of known critical mineral resources, determining geologic controls on critical mineral distribution for deposits currently producing byproducts, identifying new sources of supply through critical mineral potential mapping and quantitative mineral assessments, and promoting critical mineral discovery in all three countries.

Critical minerals are pivotal to human society in industrialised and developing economies. Many critical minerals are irreplaceable inputs for technological and industrial advancements, especially renewable energy systems, electric vehicles, rechargeable batteries, consumer electronics, telecommunications, specialty alloys, and defence technologies. Critical minerals are metals, non-metals and mineral compounds that are economically important and are also subject to high risks of supply. “Criticality” is a subjective concept; countries develop their own lists of critical minerals based on the relative importance of particular minerals to their industrial needs and strategic assessment of supply risks. Lists are reviewed and changed over time. Commonly appearing on lists of high criticality are: antimony, barite, beryllium, bismuth, cesium, chromium, cobalt, germanium, indium, lithium, manganese, niobium, platinum-group elements (PGE), potash, rare earth elements (REE), rhenium, rubidium, scandium, strontium, tantalum, tellurium, rhenium, tungsten, and vanadium. The supply of critical minerals is an area of great growth potential, based on increasing technological demands and uses at a global level. Australia is one of the world’s principal producers of several key major mineral commodities (e.g. bauxite, coal, copper, lead, gold, ilmenite, iron ore, nickel, rutile, zircon, and zinc). Although some critical minerals are mined as primary products (e.g. REE, lithium, potash), many critical minerals are extracted as companion products from base or precious metal production (e.g. PGE from nickel sulfide ores, or indium from zinc concentrate). Considering that Australia has leading expertise in mining and metallurgical processing as well as extensive mineral resources likely to contain critical minerals, there is a clear opportunity for Australia to develop into a major, transparent and reliable supplier of critical minerals for the global economy. Based on a conservative estimate, Australia could add approximately $9.4 billion of value to the nation's mineral and metal production (currently valued at $112.2 billion, or an increase of about 8%) through the production of four critical commodities (hafnium, niobium, rare earth elements and scandium) from existing mines and favourable deposits. Full realisation of this and potentially even greater production is significantly affected by other factors, including: insufficient knowledge of critical minerals in Australian deposits and their behaviour during metallurgical processing due to limited reporting by industry; few geological studies dedicated to assessing and facilitating the discovery of critical mineral resources in Australia; the need for new mining technology and services to economically extract critical minerals; gaps in capabilities of domestic smelters/refineries to process critical minerals. These issues require further research and investigation in order for Australia to maximise its position in global critical minerals markets. This study was commissioned by Geoscience Australia in collaboration with RMIT and Monash University to summarise key aspects of the current state of critical minerals in Australia. The report covers: global demand and supply; Australia’s resource potential; an overview of ‘criticality’ assessment methods; estimates of potential economic value; and future research needs for critical minerals in Australia.

This database contains geochemical analyses of over 7000 samples collected from or near mineral deposits from 60 countries, compiled by the Critical Minerals Mapping Initiative (CMMI), a collaboration between Geoscience Australia (GA), the Geological Survey of Canada (GSC) and the United States Geological Survey (USGS). Data was compiled from a number of publicly-available sources, including federal and provincial government mineral deposit and geochemistry databases, and the ore samples normalised to average crustal abundance (OSNACA) database compiled by the Centre for Exploration Targeting at the University of Western Australia. Geochemical data cover the majority of the periodic table, with metadata on analytical methods and detection limits. Where available, sample descriptions include lithology, mineralogy, and host stratigraphic units. Mineral deposits are classified according to the CMMI mineral deposit classification scheme (Hofstra et al., 2021). Location information includes deposit or prospect name, and sampling location (i.e., mine, field site, or borehole collar). This dataset will be updated periodically as more data become available.

<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)

The National Geochemical Survey of Australia (NGSA) is Australia’s only internally consistent, continental-scale geochemical atlas and dataset (<a href="http://dx.doi.org/10.11636/Record.2011.020">http://dx.doi.org/10.11636/Record.2011.020</a>). The present dataset provides additional geochemical data for Li, Be, Cs, and Rb acquired as part of the Australian Government-funded Exploring for the Future (EFTF) program and in support of the Australian Government’s 2023-2030 Critical Minerals Strategy. The dataset fills a knowledge gap about Li distribution in Australia over areas dominated by transported regolith. The main ‘total’ element analysis method deployed for NGSA was based on making a fused bead using lithium-borate flux for XRF then ICP-MS analysis. Consequently, the samples could not be meaningfully analysed for Li. All 1315 NGSA milled coarse-fraction (<2 mm) top (“TOS”) catchment outlet sediment samples, taken from 0 to 10 cm depth in floodplain landforms, were analysed in the current project following the digestion method that provides near-total concentrations of Li, Be, Cs, and Rb. The samples were analysed by the commercial laboratory analysis service provider Bureau Veritas in Perth using low-level mixed acid (a mixture of nitric, perchloric and hydrofluoric acids) digestion with elements determined by ICP-MS (Bureau Veritas methods MA110 and MA112). The data are reported in the same format as the NGSA dataset, allowing for seamless integration with previously released NGSA data. Further details on the QA/QC procedures as well as data interpretation will be reported elsewhere. This data release also includes four continental-scale geochemical maps for Li, Be, Cs, and Rb built from these analytical data. This dataset, in conjunction with previous data published by NGSA, will be of use to mineral exploration and prospectivity modelling around Australia by providing geochemical baselines for Li, Be, Cs, and Rb, as well as identifying regions of anomalism. Additionally, these data also have relevance to other applications in earth and environmental sciences.
