The Challenge

The Panton Sill in WA’s Kimberly region contains a potential resource of 14.32 million tonnes of ore at 2.19 g/t Pt, 2.39 g/t Pd (for an estimated total contained resource of c. 2 Moz of Pt+Pd) and 0.31 g/t Au.

The distribution of this mineralisation across multiple thin stratiform reefs is not amenable to economic extraction by existing mineral processing technologies.

Key Findings

A viable method of extracting Platinum Group Metals (PGMs) from the Panton Sill deposit was developed by Curtin University.

The optimal method for processing the ore was to produce a flotation concentrate, followed by conventional roasting and an HCl/NaCl/H2O2 leach.

Extraction rates achieved were 97% Pt, 90% Pd and 97% Au.

Benefit to WA

Application of the identified methodology at scale may allow the development of a viable mining operation to extract the PGMs from the Panton Sill deposit.

Commercial exploitation of this resource would bring benefits to the state including employment and royalty revenue.
