BlueRock recovers higher diamond grades from SA mine

02 july 2019

bluerockdiamonds_logo.pngBlueRock Diamonds said the average grade at its Kareevlei mine, in South Africa leaped 34% to 3.28 carats per hundred tonnes (cpht) in 2018 from 2.45 cpht, a year earlier.
The average stone size recovered in 2018 was around 0.35 carats in size and more than 90% of diamonds of gem or near gem quality.
The AIM-listed company is targeting to process between 280,000 tonnes of ore and 330,000 tonnes in 2019.
It processed 189,990 tonnes of ore from 572,664 tonnes mined in 2018.
BlueRock has now started seven-day a week, 365 days a year mining at Kareevlei.
“We now have the right strategy, the right team and sufficient funds in place to begin to really exploit this potential,” said company executive chair Michael Houston. 
BlueRock’s diamond sales rose 71% in 2018, while its revenue jumped to £1.4 million from the previous year’s £950 000.
However, the company recorded a loss before tax of £2.4 million as operations continue to move towards the economies of scale required to become profitable.
