Tender: Whole-Rock Geochemistry and Quantitative XRD Analysis – Geoscience Australia (Birrindudu Deep Dive)

About

Geoscience Australia is seeking laboratory services for whole-rock inorganic geochemistry (up to 700 prepared rock powder samples) and quantitative X-ray diffraction (up to 460 samples) as part of the Birrindudu Deep Dive project, with all analyses to be completed by mid June 2026. Suppliers may bid for Service A (geochemistry) or Service B (quantitative XRD) or both. Service A requires XRF and total-digestion ICP-MS/ICP-AES of major oxides and trace elements (including rare earth elements), Loss on Ignition, fire assay for Au, Pt and Pd, total combustion carbon and sulphur, FeO by titration, precision error better than 15%, contamination control measures, batch reports and a final report, and return of leftover material. Service B requires quantitative XRD validated against elemental assay data (provided by Geoscience Australia or obtained by the supplier), a list of minerals or mineral groups that can be quantified and solutions to quantify clays such as illite, batch reports and a final report, and return of leftover material. Samples for both services will be submitted in batches over the contract period.
