Ore and waste will be mined from the CMA pit, Yaouré pit, Govisou pit, Angovia 2 pit and the small Y-pits, complimented with the remaining stocks of previously heap leach ore stacked as part of previous decommissioned mining operations. The CMA and Yaouré pits currently provide the bulk of the ore feed sources throughout the life of mine, as currently envisaged.
The chosen method of mining is conventional open pit mining utilising hydraulic excavators and trucks, mining bench heights of 5 m with 2.5m flitches to minimise ore loss and waste rock dilution.
Inter-ramp pit slopes are 40 to 60 degrees varied by material weathering level and wall sector. Inter ramp slopes are excluding ramp but including berms spaced at between 10 and 20 metres vertically and berm widths of 5 to 7 metres.
Pit ramps have been designed for a 100-tonne payload truck fleet and are set at 24 metres (dual lane) to 16 metres (single lane).
Minimum mining width of 40 m was generally applied to the pit designs.
Perseus is currently mining the CMA orebody at the Yaouré Gold Mine in Côte d’Ivoire using conventional open pit mining methods. The CMA is a tabular zone of mineralisation 2-20 metres thick which generally grades at 3-7g/t gold and generally dips to the east at 20-35 degrees but can be shallower or steeper locally.
In FY2022, the main ore source will continue to be stages 1 and 2 of the CMA pit with additional ore being sourced fr ........
