Production resumes at Liqhobong Mine

Firestone Diamonds plc (AIM: FDI), is pleased to announce that an alternative power supply has been implemented at its Liqhobong Diamond Mine ("Liqhobong") which has facilitated the resumption of production in the absence of grid electricity supply.

Further to the announcement on 15 October 2019 and quarterly operations update on 23 October 2019, the company has successfully commissioned the rented diesel generators. Production resumed on 26 October, and the processing plant is currently operating at between 80% and 90% of full capacity as the new power generation system is being optimised.

The generators are expected to be used to generate power until grid power is restored from the Muela Hydropower Station, which, according to the Lesotho Electricity Company, is scheduled to take place on 1 December 2019. Normal operating costs are expected to increase by the cost of renting the gensets and of the associated diesel consumption.

The information contained within this announcement is deemed by the Company to constitute inside information as stipulated under the Market Abuse Regulations (EU) No. 596/2014 ("MAR").
