- BlueRock Diamonds - which owns and operates the Kareevlei diamond mine in the Kimberley region of South Africa - achieved record monthly sales of ZAR3.25m ($226,400) in October.

The company sold a record 609.84 carats (September: 544.57 carats) at an average of $371.25 per carat compared with the average price realised for the first nine months of $336.65.

The company said that as previously announced, its operations were affected by rainfall in the early part of the month which caused approximately 5 days of production to be lost.

It said: 'Production in October was therefore approximately 17,000 tonnes compared to 22,010 tonnes in September.

'Production has returned to normal levels and steps have been taken to mitigate the effect of similar amounts of rain in the future by introducing plant to produce a stockpile of covered material available for processing during rainy periods.'

The company also said that blasting and processing of the level 2 kimberlite had now begun.

It said that as previously announced, it was expected that the level 2 kimberlite would, on average, yield higher grades than that achieved from the level 1 kimberlite that the company has been processing for the last few months.
