Truck leaving Far West Decline
The ore was processed between February 11, 2019 and March 5, 2019 to produce clean, high quality concentrates:
• Copper recovery of 84.4% to a concentrate grading 26.0% copper;
• Lead recovery of 79.9% to a concentrate grading 70.1% lead; and
• Zinc recovery of 89.2% to a concentrate grading 59.3% zinc.
Importantly, the recoveries and concentrate grades are in line with, or in most cases significantly greater than, the estimates used in the Thalanga Zinc Project Re-Start Study.
The pre-production development of Far West is being completed on track and within budget.
The mine development in ore drives and the decline will continue as a normal course of operational activities.
Ventilation fans have been installed enabling commencement of second drill jumbo in April to increase underground development rates.

The decline is currently at 133 metres vertical depth. It has passed the 880 Level access and continues downwards to the 860 Level access.
Further development ore will be processed through the plant and the site team is looking forward to the commencement of stoping in Q3 CY2019.
