On 23 April 2018 Newcrest announced that the Cadia Hill open pit had been approved to use the first 200 metres as tailings disposal for Cadia East and that it would be likely, subject to further study, that the remnant Mineral Resource and Ore Reserves of Cadia Hill open pit would ultimately be forgone.
The SMC Test is a laboratory comminution test which provides a range of information on the breakage characteristics of rock samples for use in the mining/minerals processing industry.
10/29/2015· The mill handles 70 per cent of ores produced at Cadia, and while a second smaller mill exists on site, the mine's production will be dramatically lower during the December quarter at least.
The Ridgeway deposit lies 500m below the surface, 3 kms north-west of the Cadia Hill open cut mine, and was discovered in November 1996. It is notably rich in Au with an inferred and indicated resource of 44 Mt at 2.6 g/t Au and 0.82% Cu, and is currently under development as .
Cadia Hill is an open pit mining operation that annually produces approximately 300,000 ounces of gold and 23,000 tons of copper. With reserves of 200 million tons of 0.73 g/t gold ore and an annual processing throughput of 17 million tons, this mine has an expected life of 12 years.

A high grade gold core is found at depth towards the eastern end of this vein package. Smaller pods of higher grade material are located above and lateral to the high-grade core. The Cadia Hill deposit is a sheeted quartz vein system located almost entirely within the quartz monzonite porphyry phase of the Cadia Intrusive Suite.
10/22/2015· Newcrest's Cadia mine's SAG mill has been shut down following motor issues. On Saturday a problem was detected with the motor on concentrator 1 SAG mill, Newcrest said in a company statement.
The design of the 40-foot diameter SAG mill installed at the Cadia Gold Mine, New South Wales Australia, followed after two years of an extensive laboratory.
A two-stage grinding process forms a part of the comminution circuit. The grinding circuit comprises a 6.5MW SAG mill and 6.5MW ball mill. Using similar processes to the adjacent Cadia Hill concentrator, gold and copper are recovered in a conventional floatation circuit to produce a copper concentrate containing elevated gold levels.
