BlueRock Diamonds PLC (BRD.L) Q3 Production Update

BlueRock Diamonds PLC, the AIM listed diamond producer, which owns and operates the Kareevlei Diamond Mine (‘Kareevlei’) in the Kimberley region of South Africa, is pleased to announce its Q3 2021 production update.


BlueRock Executive Chairman, Mike Houston, said, “With 7,682 carats produced, this has been another record quarter driven by quality high-grade kimberlite being mined and the new crushing plant providing a consistent feed to the old three-pan processing plant. It augurs well for the transition to the new four-pan plant, which will be completed during October.

“The grade and quality of diamonds has been very encouraging and as previously reported we discovered four high value diamonds during the quarter sold for over $1 million, including a record 58.6 carat stone. The size of this stone at more than double our previous largest stone supports the potential of the Kareevlei resource.

“The market for rough diamonds has remained firm throughout the quarter with strong buyer participation at the South Africa tenders and a growing interest for Kareevlei diamonds as reflected in our average price of $554 per carat, the highest quarterly price achieved by the Company. This average quarterly price has obviously been influenced by the four high value stones recovered, however, the year-to-date average price achieved is an excellent $486 per carat.

“I have provided an update of progress on the expansion project below and look forward to updating shareholders again soon.”


Mining Development

This is an ongoing process and the year-to-date development tonnage at 997kt is 69% up on the 2020 figure. Above life of mine strip ratio development, mining will continue through Q4 2021 with the objective of providing access to quality kimberlite throughout the forthcoming wet season. The Company has built up a 90,000t run of mine inventory as at the end of September 2021.

Processing Plant

The new crushing circuit has been operating for some months with steady improvements made. The upgraded screen has now been fitted and will be brought up to full production ahead of the full processing plant being brought on-line.

Line 1 of 2 is now operational and will reach full production over the next two weeks. Importantly, much of Line 2 will be fully commissioned during this period prior to the final transfer and fitting of two pans currently being used in the old plant. Once management is confident Line 1 is producing at design capacity, the old plant will be switched off and Line 2 brought into production. It is planned that this will be completed by the end of October with the overall plant now expected to be fully operational in early November.

The Mining, Processing and Engineering teams have been strengthened to meet the demands of the increased volumes and higher-tech processing plant. On-plant safety and operational training has and will continue to be a key focus during the commissioning /ramp-up phase.


The current guidance for 2021 and 2022 remains unchanged as follows:
