BlueRock narrows H1 losses as grades improve at Kareevlei

21 september 2018
BlueRock Diamonds reduced its loss for the first half of the year to £789,000 from a £1.3 million loss, a year earlier as average grades and production improved at its Kareevlei mine in South Africa.
The mine’s average grade for the period was 3.17 carats per hundred tonnes (cpht) compared to 2.26 cpht in 2017, while production increased 81 percent year-on-year to 73,028 tonnes from 40,343 tonnes, the previous year.
It said its average value per carat was $340 during the period under consideration compared to $362 in the first half of 2017.
BlueRock chairperson Paul Beck said the improved production volumes were achieved despite a seasonal downturn during the period coupled with a previous fault with a crusher that had temporarily stopped production in June.
“Post-period end, all issues with the crushing circuit have now been resolved and we are operating at approximately 50 percent increase in throughput with average tonnes processed per day approaching 1,500 tonnes,” he said.
Beck also said that the development work BlueRock was conducting at KV2 would provide them with “good quality” high grade kimberlite in 2019 as they “look forward to the results from [the] new pipe at KV1 with enthusiasm”.
