The processing plant comprises a conventional crushing and grinding circuit. The ore is mined from an open-pit mine requiring significant onsite infrastructure including power plant, camps, mine services and mine support buildings.
The project was based on processing 4,000tpd of ore through a conventional leach-CIP gold plant at an average grade of 4.1 g/t Au.
Other improvements include:
• Optimised and energy-efficient comminution circuit (primary crusher, SAG, vertimill)
• Leach-CIP (carousel) circuit and to minimise gold lock-up
• Split AARL elution (greater flexibility can increase strips/week)
• Optimised layout
The initial DFS was completed in February 2016 with EPCM contract awarded in April 2016. First gold pour June 2018.
