Aim-listed diamond producer BlueRock Diamonds, which owns and operates the Kareevlei diamond mine, near Kimberley, in South Africa’s Northern Cape, has had a “disappointing” second quarter as a result of excessive rain, BlueRock executive chairperson Mike Houston said on July 11. “The extreme weather conditions, which saw 145 mm of rain fall during the period compared with 9 mm of rain recorded for the corresponding period in 2021, are reflected in what is a disappointing quarter, with production significantly less than budget,” he explained.
