Lucapa Diamond Company has discovered a 133.4-carat diamond at its Lulo project in Angola.
The miner said it also found other stones weighing 29.2 carats, 12.37 carats and 11.1 carats – while processing 15,000 cubic meters of alluvial gravels from mining blocks six and eight.
The 133.4-carat diamond is the largest diamond recovered to date at Lulo, slightly larger than the 131.4-carat D-color Type IIa diamond recovered from bulk sampling nearly four years ago.
“While the compound 133.4 carat diamond is not of high quality, the recovery of this large stone and three other specials … underlines the potential for mining block six to be another significant source of large alluvial diamonds. The fact the 133.4-carat stone is a compound diamond which is unlikely to have travelled very far from its primary source and its relative downstream proximity to mining block eight and our high priority-kimberlite targets we believe is very significant,” the company said in a statement.
