At the West Flotouo deposits and the NE extension (Flotouo Extension) was focussed on growing the existing resources and expediting their incorporation in the current mining plan. At Colline Sud, drilling was focussed on identifying extensions to the current mineralisation, which will be followed up in in Q2-2022.
