Hydraulic mining of the tailings dam is underway with two cannons in action.
The operations team trained through August, which led to progressive improvements in performance. Operators are maintaining consistent high slurry density of 40% to 50% solids. The target is for a minimum of 37% solids.
An upgrade of slurry winning pumps and high pressure hose fittings has reduced the downtime that dogged the operation.
Those mining operations are achieving a consistent flow rate of 5 million tonnes per annum to 6Mtpa.
The focus for the hydraulic miners is to ensure consistent feed to the processing plant and to progressively ramp up to the initial phase 1 target flowrate of 8Mtpa.
The process plant has been refurbished and has up to 8Mtpa capacity ava...
