JOHANNESBURG (miningweekly.com) – After last month appointing Italian firm RCT to undertake a maiden 1 000 m diamond drill programme at its Lac Dinga project, in the Republic of Congo (ROC), Aim-listed African Potash said on Monday that the rig had now been mobilised and was expected to start drilling within a few days.
The objective of the programme was to test the interpreted prospective salt sequence for the development of high-grade sylvinite horizons within the basin-wide carnallite.
This followed an earlier geological study, which resulted in a regional structural geological framework and an interpretation of the extent of the evaporite sequence across the project area, confirming the stratigraphic-structural continuity of the salt into the Lac Dinga area.
The first phase drill programme, which would consist of two vertical rotary/diamond drill holes to a depth of 500 m, would test two high-priority targets that demonstrated the potential for high-grade potash mineralisation based on the interpretation of seismic data.
The holes were expected to intersect the evaporite horizon between 300 m and 350 m below surface
