What was developed or tested
Geochemistry and mineralogy identify metal deportment and candidate recovery routes including flotation, gravity, cyanidation and bioleaching.
What the evidence supports
A strong Australian characterise-first case. The Cosmo work identified anomalous metals and host minerals, but resource definition, recovery testing and economics remain gates.
Environmental and technical uncertainty
This is prospectivity work, not a recovery project. Any pathway must integrate acid-forming minerals, arsenic and rehabilitation outcomes.
Benefit-case screening lens
Potential value: Recovered metal revenue, critical-mineral supply, improved resource efficiency and possible reduction of a legacy or active tailings inventory.
Deployment constraints: Representative grade, mineral deportment, recovery, throughput, reagents, energy, CAPEX, commodity price and management of the reprocessed residue.
Question before applying elsewhere
Do grade variability, mineral deportment, recovery, reagent demand and residual-waste management support a viable site-specific flowsheet?
