BlueRock DiamondsPLC (BRD.L) Expansion Project 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 an update with regards to its transformational 1 million tonnes per annum (‘Mtpa’) expansion project.


· Successfully operated all key areas of the upgraded plant at design capacity on a short-cycle basis during the hot commissioning phase

· Positioned to meet FY21 guidance target of 22,000 to 26,000 carats having produced 19,362 carats as at 3 November 2021

BlueRock Executive Chairman, Mike Houston, said, “We remain confident of achieving our targeted guidance; at 3 November 2021 we had produced a total of 19,362 carats during the year with a further seven weeks of production available to the year end. Significant cost and operating efficiency benefits are anticipated once the new plant is running at capacity.”


The Company is focused on completing an expansion project aimed at increasing tonnages at Kareevlei to provide the economies of scale to turn the mine into a highly cash generative asset. Having run all key areas of the plant at design capacity on a short-cycle basis during the hot commissioning phase, the team has been making minor modifications to the processing circuit on both lines to adjust to the higher volumes and mix of ore.

As noted in its Q3 production update (see RNS dated 13 October 2021), the Company planned to continue to operate the old plant until it was confident that the first line of the new plant was functioning at design capacity on a sustained basis. Using this configuration, volumes in excess of 3,000 tonnes a day have been achieved, which would be sufficient to achieve the Company’s target of 1 Mtpa. The move to operating both new lines should increase volumes further and reduce costs towards target levels.

Given the volumes that the Company is achieving using the current configuration, the old plant will now operate alongside Line 1 until the new plant has been completely debugged in order to maximise production levels over the next couple of months. This both ensures that the Company is well positioned to meet guidance of 22,000 to 26,000 carats produced for the year ended 31 December 2021, while also maximising cash inflow in a situation where the Company is carefully managing limited cash resources having recently repaid half of the convertible loan note originally issued in 2014 amounting to £462,500 in accordance with its revised agreed terms.
