<div>The 2024 Critical Minerals in Ores (CMiO) Database factsheet contains information about the purpose of the CMiO, provides links to access the CMiO, two case studies on critical mineral abundance in deposits and a link to the user guide and submission template to provide data to the CMiO. This factsheet is an is an updated version of the Kelley 2020 USGS factsheet (https://doi.org/10.3133/fs20203035). The CMiO was produced through 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) in 2021 and is periodically updated. Note: A copy of the updated factsheet will not be available until the end of 2024.

The Australian Resource Reviews are periodic national assessments of individual mineral commodities. The reviews include evaluations of short-term and long-term trends for each mineral resource, world rankings, production data, significant exploration results and an overview of mining industry developments.

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.

<div>Disruptions to the global supply chains of critical raw materials (CRM) have the potential to delay or increase the cost of the renewable energy transition. However, for some CRM, the primary drivers of these supply chain disruptions are likely to be issues related to environmental, social, and governance (ESG) rather than geological scarcity. Herein we combine public geospatial data as mappable proxies for key ESG indicators (e.g., conservation, biodiversity, freshwater, energy, waste, land use, human development, health and safety, and governance) and a global dataset of news events to train and validate three models for predicting “conflict” events (e.g., disputes, protests, violence) that can negatively impact CRM supply chains: (1) a knowledge-driven fuzzy logic model that yields an area under the curve (AUC) for the receiver operating characteristics plot of 0.72 for the entire model; (2) a naïve Bayes model that yields an AUC of 0.81 for the test set; and (3) a deep learning model comprising stacked autoencoders and a feed-forward artificial neural network that yields an AUC of 0.91 for the test set. The high AUC of the deep learning model demonstrates that public geospatial data can accurately predict natural resources conflicts, but we show that machine learning results are biased by proxies for population density and likely underestimate the potential for conflict in remote areas. Knowledge-driven methods are the least impacted by population bias and are used to calculate an ESG rating that is then applied to a global dataset of lithium occurrences as a case study. We demonstrate that giant lithium brine deposits (i.e., >10&nbsp;Mt Li2O) are restricted to regions with higher spatially situated risks relative to a subset of smaller pegmatite-hosted deposits that yield higher ESG ratings (i.e., lower risk). Our results reveal trade-offs between the sources of lithium, resource size, and spatially situated risks. We suggest that this type of geospatial ESG rating is broadly applicable to other CRM and that mapping spatially situated risks prior to mineral exploration has the potential to improve ESG outcomes and government policies that strengthen supply chains. <b>Citation:</b> Haynes M, Chudasama B, Goodenough K, Eerola T, Golev A, Zhang SE, Park J and Lèbre E (2024) Geospatial Data and Deep Learning Expose ESG Risks to Critical Raw Materials Supply: The Case of Lithium. <i>Earth Sci.

<div>GeoInsight was an 18-month pilot project developed in the latter part of Geoscience Australia’s Exploring for the Future Program (2016–2024). The aim of this pilot was to develop a new approach to communicating geological information to non-technical audiences, that is, non-geoscience professionals. The pilot was developed using a human-centred design approach in which user needs were forefront considerations. Interviews and testing found that users wanted a simple and fast, plain-language experience which provided basic information and provided pathways for further research. GeoInsight’s vision is to be an accessible experience that curates information and data from across the Geoscience Australia ecosystem, helping users make decisions and refine their research approach, quickly and confidently.</div><div><br></div><div>Geoscience Australia hosts a wealth of geoscientific data, and the quantity of data available in the geosciences is expanding rapidly. This requires newly developed applications such as the GeoInsight pilot to be adaptable and malleable to changes and updates within this data. As such, utilising the existing Oracle databases, web service publication and platform development workflows currently employed within Geoscience Australia (GA) were optimal choices for data delivery for the GeoInsight pilot.&nbsp;This record is intended to give an overview of the how and why of the technical infrastructure of this project. It aims to summarise how the underlying databases were used for both existing and new data, as well as development of web services to supply the data to the pilot application.&nbsp;</div>
