The company reported a loss of GBP 381,027 ($458,064) fromits Kareevlei mine in South Africa for the six months ending June 30, comparedwith a loss of GBP 1.3 million ($1.6 million) the previous year.

Production was 4,936 carats, up from 2,438 carats the previous year. Production levels in May and June were twice as high as those for the same period a year ago, after the company appointed a new managementteam in April, and changed its operation. BlueRock appointed Gus Simbaganevi CEO of Kareevlei, and took on Teichmann Group as a strategic investor in the company.

It will create stockpiles of run-of-mine rough and crushed ore to offset the impact of the rainy season, during which operations are difficult.Image: A rough diamond from Kareevlei.
