The Ridgeway underground mine and Cadia Extended open cut mine were developed shortly afterwards and commenced production in 2002 and 2003, respectively, with Ridgeway expanding into block cave mining in 2009. Collectively, Cadia Hill and Ridgeway produced over 8Moz of gold and nearly 860kt of copper concentrate over their mine lives through 2018 following which the Cadia Hill deposit was largely exhausted and Ridgeway was placed on care and maintenance in March 2016 with minor production resumed during 2017 to supplement plant feed following the Cadia East seismic event in April 2017.
Ridgeway is currently on care and maintenance subject to further studies, all necessary approvals, permits, internal and regulatory requirements and further works. |
