Australia’s Lucapa Diamond (ASX:LOM) said Thursday production at its 40%-owned prolific Lulo project, in Angola, rose 20% during the June quarter.

Production at the mine, which has yielded massive diamonds this year, reached 5,058 carats during the three months to June, up from the 4,203 carats in the previous corresponding period, the company said.

The diamond production increases, said the company, were generated from a 27% rise in mining volumes to 72,671 bulk cubic metres – a record quarterly result.

Sales in the period were up 6% when compared to the same quarter last year, to hit $5 million. After that, Lulo has been left with a diamond inventory of 2,755ct, 61% higher than what it had last year in the same quarter.
