Work at the CMA Underground prospect focused on infill drilling to firm up previously defined underground resources extending below the currently planned CMA pit. Perseus defined an Inferred Mineral Resource of 1.8 million tonnes grading 6.1 g/t Au, extending to a maximum 275 metre down dip beneath the open pit resource (refer Resources and Reserves ASX announcement dated 24 August 2021), with potential to extend mineralisation further down dip beyond this ( Appendix 1 – Figure 1.2 ). Perseus has also completed a Scoping Study that identified the potential to mine the CMA structure using underground mining methods (refer to ASX Release ' Perseus Mining Completes Scoping Study for Potential Underground Mine at Yaouré ' dated 5 November 2018).
