Metallurgical variability test work returns low-90s recovery on Anvil Zone composites

Variability metallurgical test work on composite samples from the Anvil Zone shear package has returned gold recovery in the low 90s per cent range using a gravity-plus-leach flowsheet, consistent with the free-milling character expected from a shear-hosted, low-sulphidation gold system.

The comminution parameters used to size a prospective grinding circuit — including the Bond work index for the andesite host rock — are published on the technical data page, alongside a calculator that lets a visitor run their own feed size and throughput assumptions against the same published equation we use internally.
