Letšeng Diamonds royalty rate:
As reported in the Half-Year Report 2026, Letšeng Diamonds was granted a royalty remission up to the end of September 2026. Post the Period, the Government of Lesotho approved a variable royalty rate of between 3% and 6%, to be determined on the six-monthly average dollar per carat. This is effective for sales post 1 October 2026.
Group facility renewal update:
The Group’s revolving credit facilities expire on 21 December 2026. The renewal of the facilities is progressing, and commercial terms and conditions are currently being finalised with Nedbank Limited and Standard Bank.
Gem Diamonds' CEO, Clifford Elphick, commented:
"Sales of Letšeng’s rough diamonds in September achieved good prices, with results further supported by the sale of the exceptional 347 carat Lesotho Jubilee. These results are encouraging indicators that demand and prices for Letšeng quality diamonds are firm.
The agreement by the Lesotho Government to introduce a variable royalty rate of between 3% and 6% is a good policy decision ensuring the long-term sustainability of the mine. We value the continued support of our funders, Nedbank and Standard Bank, as we progress the refinancing of our debt facilities.”
