Industry Geochemistry Compilation Pilot Project: National Drillhole Geochemistry Data

Geoscience Australia's Pilot Project evaluated creating a national, open-file industry drillhole geochemistry dataset from March to June 2025. The project produced a cleaned and validated compilation of multi-element geochemical data for Western Australia and a proposed data architecture for a national scale compilation. Key outputs include modular Python code for data cleaning and a business case review of state and territory geological survey holdings.

Use Cases

• Training mineral prospectivity models based on multi-element geochemical data.
• Developing standardized data cleaning workflows for industry-reported geochemistry.
• Assessing the feasibility of a national geochemical data compilation across jurisdictional borders.
• Analyzing spatial trends in geochemistry using the provided drillhole data.

Strengths

• Project ran from March to June 2025, providing a defined timeframe.
• Includes a cleaned and validated case study dataset for Western Australia.
• Workflow delivered as modular, efficient, and well-documented Python code.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the pilot's Western Australia case study.
