South African diamond miner BlueRock Diamonds, which is listed on the London Aim and operates the Kareevlei mine, in Kimberley, in the Northern Cape, has raised £2.1-million through the placing of six-million shares at 35p a share. The net proceeds will be used to provide additional working capital to enable BlueRock to implement an upgraded mining plan to ensure consistent supply of quality ore to the processing plant, as well as to pay its mining contractor Teichmann to accommodate the impact of two operational shutdowns in the fourth quarter of 2021.
