10 july 2019

bluerockdiamonds_logo.pngBlueRock Diamonds produced 3,516 carats at its the Kareevlei Diamond Mine in South Africa in the second quarter of 2019, which is four times than the 875 carats it produced, a year earlier.
It recorded a grade of 4.46 carats per hundred tonnes during the period under review compared to 2.45 carats per hundred tonnes the same period, in 2018.
Company executive chairperson Mike Houston attributed the growth to an impact that their new chief executive at Kareevlei and his team had made. 
“The immediate impact of the new team gives us confidence in our ability to take production to the next level,” he said.
“Once we have achieved our key objective of operating the company profitably, which we expect to happen in the second half of 2019, we will explore how to increase production volumes further to the optimum level which the resource can comfortably sustain.”
BlueRock’s average price for the period was $430 per carat on sales of 2,517 carats from 875 carats sold at $305 per carat in the second quarter of 2018.
A 24.9 carat stone was sold for $190,000 in June.
The company’s revenue jumped to $1.08 million in the second quarter from $270 000, a year earlier.
