Full-scale Flow Marker Experiments at the Ridgeway Deeps
2016-5-9 Initial marker experiments were undertaken in the Ridgeway sublevel cave (RW) (2002), and subsequently at Ridgeway Deeps (RWD) (2008) and Cadia East PC1 (CEPC1) (2012) block caves. Over 25 000 markers have been installed at the three caving operations to date (approximately 20 000, 3000 and 2500 for RW, RWD and CEPC1 respectively).

The Ridgeway Deeps Lift 1 block cave operation was mined between 2007 and 2015 and was Newcrest’s first block cave operation. The change to block caving was introduced after the identification that the grade profile for Ridgeway was declining to the point where subsequent SLC levels below the 5040 mRL were uneconomic.
