十一月 26, 2018

BlueRock Diamonds plc which owns and operates the Kareevlei Diamond Mine in the Kimberley region of South Africa, announced that the grade resulting from mining the first level of its latest kimberlite pipe “exceeds expectations”, writes TheDiamondLoupe. BlueRock is currently mining two of the five pipes at Kareevlei, called the KV1 and KV2. It processed the first Level 1 ore (10m to 20m below surface) from KV1, totalling 20,500 tonnes, resulting in grades of between 3.90 carats per hundred tonnes (‘cpht’) and 5.11 cpht at an average grade of 4.51 cpht. The average grade in 2017 when mining exclusively from KV2 was 2.45 cpht and in H1 2018 was 3.17 cpht, also from KV2. KV1 has a grade of 6.3 cpht.

According to BlueRock, the Kareevlei mine produces very high quality diamonds. The average value of all diamonds sold from Kareevlei exceeds US$300 per carat, placing it among the top 10 kimberlite mines in the world (ranked by average value per carat).
