London-listed Petra Diamonds reported higher diamond production for the quarter ended March 31 – the third quarter of the company’s 2023 financial year – following improved run-of-mine (RoM) grades and tailings production at the Cullinan mine, in South Africa, and increased throughput at the Finsch mine, in South Africa, CEO Richard Duffy says. He adds that the company expects to deliver on its revised guidance of 2.75-million to 2.85-million carats for the full-year to end June 30.
