Critical minerals are a collection of metal and non-metal commodities considered essential for economic and industrial development, and for which there are significant concerns around future supply due to resource scarcity or geopolitical factors. The Geological Survey of South Australia's Critical Minerals South Australia (CMSA) project focuses on advancing knowledge to support critical minerals discovery and exploration in South Australia.

The CMSA project, through the "Critical mineral potential of South Australia" report book series, reviews and identifies key mineralisation styles for defined critical minerals, maps existing critical mineral occurrences across the State and identifies regions with significant critical mineral potential aiming to increase industry and investor understanding of South Australia's critical mineral potential.

The Report Book includes: - Overview of uses for beryllium - Review of economic beryllium deposit types - Beryllium occurrences and prospectivity in South Australia - Maps of South Australia’s beryllium occurrences and characteristic beryllium forms - Excel spreadsheet combining all occurrence data for beryllium available from South Australia’s Mineral Deposit (MinDep) database.
