Gem Diamonds Limited (GEMD:LSE) The company is on track to achieve full year production guidance at Letšeng, despite extreme weather disruptions. In Q3 2016 : 24,388 carats were recovered at Letšeng, compared to 28,682 carats in Q2 2016. The weather conditions restricted access to the pits, therefore ore was sourced from surface stockpiles which resulted in a reduction of grade recovered. CEO, Clifford Elphick commented: "Prices achieved for Letšeng's high quality diamonds have remained robust". During the sales period of 1 July 2016 to 30 September 2016: 37,990 carats were sold for proceeds of US$61.5 million, achieving an average price of US$1,619 per carat.

Included in the sales figures are small diamonds to be sold in the final sale in December 2016. The average price attained year to date is US$1,785/carat, as there were fewer than expected +100 carat diamonds recovered.
