Chalice Mining Limited (ASX: CHN) has provided an update on the ongoing pre-feasibility study (PFS) for the 100%-owned Gonneville PGE-Ni-Cu-Co Project, located on Chalice-owned farmland ~70km north-east of Perth in Western Australia.
Exceptional test work results demonstrate that two saleable, smelter-grade flotation concentrates can be produced across the entire Gonneville sulphide resource:
- Cu-PGE-Au concentrate grading 22-26% Cu, 45-60g/t 3E
- Ni-Co-PGE concentrate grading 7.5-8.7% Ni, 0.8% Co, 18-20g/t 3E
Managing director and CEO Alex Dorsch said, “The ability to produce a saleable nickel concentrate across the grade spectrum of the entire Gonneville Resource is a major breakthrough and fundamentally simplifies the world-class Gonneville Project. This is the step change we have been hoping for over the last two years.”
In addition, conventional CIL leaching recovers additional palladium and gold from the flotation tails, with recent optimizations resulting in significantly reduced reagent consumption and operating costs relative to the 2023 scoping study.
This recent breakthrough means the project will not require a hydrometallurgical process for the nickel concentrate, which substantially reduces technical risk, process complexity and capital and operating costs.
The company has also highlighted its strong financial position, with A$90M in cash and listed investments.
