The Lulo kimberlite exploration program aims to identify the primary hard-rock sources of the exceptional alluvial diamonds being mined at Lulo.
The list of kimberlite targets at Lulo was revised in mid-2017 following the completion of an extensive 8,566 line km Time Domain Electromagnetic (TDEM) survey flown over the Cacuilo River area where the high-value alluvial mining operations are centred and further to the south-east.
Lucapa and its partners are utilising up to three drilling rigs to systematically drill test the kimberlite targets.
The ongoing drilling program has three main objectives:
- To determine which of the identified targets are kimberlites
- To recover core material from confirmed kimberlites for petrography, indicator mineral recoveries and mineral chemistry analysis
- To use those laboratory results to prioritise a much-reduced number of potentially diamondiferous kimberlite pipes for further drilling and bulk sampling
The kimberlite exploration program is being funded from Lucapa’s share of distributions from the alluvial diamond mining operations.
Drilling and sampling will continue throughout 2018, in parallel with the alluvial mining operations.
