53 drilling targets at Lulo diamonds
By providing updates on Lulo diamond project in Angola Lucapa Diamond Company Limited said, the kimberlite exploration program is designed to identify the primary hard-rock source or sources of the exceptional alluvial diamonds mined at Lulo, the world’s highest average US$ per carat alluvial production.
The Lulo partners are systematically drilling ~80 targets in the current campaign proximal to, and/or upstream of, the alluvial mining blocks. Drill core from the confirmed kimberlites is progressively logged and exported in batches to laboratories in South Africa and Canada for mineral chemistry analysis.
Further Lucapa has received the mineral chemistry results on loam samples sent to the laboratory. A micro-diamond was recovered from a pit sample at kimberlite L204, which also recorded a strong lherzolitic garnet chemistry signature, which is also closely associated with diamonds. In addition, diamond-associated G3D, G4D and G10D garnets were recovered from seven Lulo kimberlites.
