DEVELOPMENT PLAN
The Study evaluates the development of the Casino deposit as a conventional open pit mine, concentrator complex, and heap leach operation. The initial production will focus on the deposit's oxide cap as a heap leach operation to recover gold and silver in doré form. The main sulphide deposit will be processed using a conventional concentrator to produce copper-gold-silver and molybdenum concentrates. Key metrics of the processing plant are shown below:
