BlueRock Diamonds said production at its Kareevlei mine, in the Northern Cape, South Africa, is now in excess of 20 000 t/m and will soon reach 25 000 t/m.
Mining Weekly reports that the average grade at the mine also continued to increase and reached 3.01 carats per hundred tonnes during the September tender, while the average value per carat achieved during the six months to June 30 was $320/ct.
This, it said, leaped to $343/ct post the end of the six months.
Meanwhile, BlueRock said would soon commence blasting of Level 2 kimberlite in the K2 pit. The Level 1 kimberlite contains a significant amount of calcrete, while Level 2 comprises pure kimberlite and is, therefore, likely to produce a higher grade than the Level 1 kimberlite, Mining Weekly reports.
The company was also planning to expand its operations through developing existing mining right or by acquiring rights to mine other areas.
