Q4 2016

Rough diamond production1 for Q4 2016 increased by 10 per cent to 7.8 million carats compared with Q4 2015 when production was reduced in response to trading conditions. The increase also reflected the ramp-up of Gahcho Kué.


Production increased by 15 per cent to 5.4 million carats. At Jwaneng, production increased 40 per cent, partly offset by Orapa, which decreased by six per cent, and Damtshaa (a satellite operation of Orapa), which was placed on care and maintenance from 1 January 2016.


Production decreased marginally to 1.4 million carats, mainly due to the sale of Kimberley Mines in January 2016, partly offset by an increase of 18 per cent at Venetia due to the processing of higher grades.


Production increased by six per cent to 428,000 carats due to increased material processed by the Debmarine Namibia fleet.



Production increased by 13 per cent to 497,000 carats, driven by the ramp-up at Gahcho Kué. This was partially offset by Snap Lake being placed on care and maintenance in December 2015. The ramp-up of Gahcho Kué continues to progress, with commercial production expected to be reached during Q1 2017.

Rough diamond production increased by 24 per cent compared with Q3 2016 as a result of higher production at Orapa, higher grades at Venetia and the ramp-up of Gahcho Kué.


Total rough diamond sales volumes in Q4 2016 compared with Q4 2015 more than doubled to eight million carats (7.5 million carats on a consolidated basis2). 

For the full year, total rough diamond sales volumes increased by 55 per cent to 32 million carats (30 million carats on a consolidated basis2). The increases reflect the improved trading conditions from those experienced in H2 2015.

For the full year, the average realised price of US$187 per carat was 10 per cent lower than in 2015, reflecting the lower average rough price index, which was down 13 per cent, partially offset by a stronger product mix.


1 De Beers production is on a 100 per cent basis, except for the Gahcho Kué joint venture which is on an attributable 51 per cent basis.
2 Consolidated sales volumes exclude De Beers’ JV partners’ 50 per cent proportionate share of sales to entities outside The De Beers Group of Companies from the Diamond Trading Company Botswana (DTCB) and the Namibia Diamond Trading Company (NDTC).
