Newcrest Mining announces that the Cadia East mine near Orange in Central West New South Wales has reached a major milestone with the safe propagation of Panel Cave 1 through to the surface, significantly ahead of expectations.
The propagation connects the broken rock of the cave to the surface, reducing production risk and increasing draw flexibility. The breakthrough means production becomes less constrained providing more flexible ore extraction.
Newcrest’s managing director and chief executive Sandeep Biswas says, “Newcrest has developed world-class expertise in bulk underground mining techniques gained from the establishment of the Ridgway sub level cave and block cave, and the Telfer sub level cave. This experience has led to the successful achievement of this critical milestone of the project ahead of time.
“Cadia East is a world-class operation achieving low All-In Sustaining Costs with a long reserve life. It is a major source of production and cash flow growth for the group.”
Cadia East development is now focused on the propagation of Panel Cave 2 and the connection of the two caves.
