BlueRock Diamonds PLC said March 15 that it got permission to allow continuous operations at the Kareevlei diamond mine in South Africa.
Despite getting the permits slightly later than expected, the company said there was no material impact on the first-quarter production guidance of between 35,000 and 45,000 tonnes.
BlueRock expects first-quarter production to be closer to the upper end of the range.
CEO Adam Waugh said the move to continuous operations will significantly increase production volumes and support the company's move toward profitability.
In November 2018, the company outlined plans to open up the KV1 and KV2 kimberlite pipes, two of five being mined at Kareevlei, in a bid to supply about 40,000 tonnes of ore per month to its processing plant starting in the third quarter of 2019.
