The 2021 production guidance, as reported on 11 March 2021, remains on target.

Covid-19

The Group continues to meticulously implement its wide range of Covid-19 protocols, health and safety measures and other precautions to protect its employees and contractors at its operations. This has had a positive effect in containing infections across the Group and has allowed operations to continue in a safe and responsible manner.

The Group continues to provide support to its workforce, contractors and surrounding communities in its efforts to curb the spread of the virus in all countries where it operates.

Corporate and Financial

The Group ended the Period with US$26.9 million of cash on hand (excluding US$8.2 million of the March tender proceeds received after the Period end). Drawn down facilities amounted to US$15.2 million resulting in a net cash position of US$11.7 million at Period end (Q4 2020: net cash of US$34.6 million).

The Group had undrawn and available facilities of US$59.6 million at Period end.

During the Period, LetSeng paid the remaining dividend of US$10.0 million which was declared in 2020. This resulted in a net cash flow of US$6.7 million to Gem Diamonds and a cash outflow from the Group of US$0.3 million relating to withholding taxes and US$3.0 million in respect of the Government of Lesotho's share of the dividend.

During the Period, LetSeng settled its 2020 income tax obligations resulting in a US$11.7 million payment to the Lesotho Revenue Authorities.

The targeted US$100 million in incremental revenue, productivity improvements and cost savings over the 4-year period to end 2021 remains on target to be delivered.

The process to sell Ghaghoo continues.

Gem Diamonds' CEO, Clifford Elphick, commented: 'It is pleasing to see that carat production during the Period was up some 11% on the same period in 2020 and that the average price of US$1 630 per carat was also slightly up on Q1 2020. Although the production from the mining mix was not as impressive as the second half of 2020, with fewer large diamonds recovered due to the areas accessed under the mining plan, prices achieved on a like for like basis remained strong for LetSeng's high value diamond production.

It is anticipated that the mining mix should improve over the coming months as the richer parts of the Satellite pit are accessed in accordance with the mine plan.'
