Caijiaying Mine Operations

Caijiaying is located in a mining region with established infrastructure, access to power and a skilled workforce. The operation has been optimised over time to improve recoveries and throughput.

Metal Mix and Revenue

Zinc is the largest contributor by volume, while gold and silver add valuable by-product income. Lead and copper provide further diversification.
