Letšeng Diamonds has highlighted the recovery of a 163 carat yellow type 1 diamond, with no breakage on 24 June 2020.
Earlier in February, Gem had recovered an exceptional 183 ct white Type IIa diamond from the Letšeng mine, the highest dollar per carat kimberlite diamond mine in the world.
It has also recovered two other significant high-quality diamonds, weighing 89 ct and 70 ct, respectively, this year.
The discoveries follow the renewal of the mining lease in November last year.
The terms of the renewed mining lease were agreed with the Lesotho Mining Board, following a statutory negotiation process. The lease was renewed for an immediate period of ten years, with exclusive rights granted to Letšeng to renew the mining lease for a further ten years.
The renewal follows on the back of Letšeng’s high-value large diamond production having experienced price pressure during the third quarter, ended September 30.
Letšeng’s plants treated 1.5-million tonnes of ore during the three-month period prior to this, of which 400 000 t was sourced from the Satellite pipe and 1.1-million from the Main pipe.
