National-Scale Critical Mineral Potential Assessments for Australia

Geoscience Australia delivers national-scale mineral potential assessments for critical minerals and strategic materials needed for the net zero transition by 2050. These assessments integrate new and legacy geoscience data to delineate prospective belts for mineral systems like nickel-copper-platinum group elements and rare earth elements. The work is part of the Resourcing Australia's Prosperity initiative and was presented at the 2025 Society of Economic Geologists Conference.

Use Cases

• Identify prospective exploration areas based on integrated geological, geophysical, and geochemical criteria.
• Train data-driven models for mineral potential using statistics or machine learning on known deposit data.
• Support government decision-making on critical mineral strategy using an evidence-based assessment.
• Reduce the exploration search space for critical mineral deposits to promote increased investment.

Strengths

• Assessments cover multiple critical mineral systems, including nickel-copper-platinum group elements and rare earth elements.
• Integrates both new and legacy geoscience data from a national-scale program.
• Uses a mineral systems-based approach to model commodity potential across all of Australia.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified as the last metadata update was 2026-06-24.
