(Alliance News) - Shares in Firestone Diamonds PLC tumbled on Friday after it said production has been hampered at a mine in Lesotho due to power supply issues.
The stock was trading 27% lower at 0.53 pence each in London on Friday afternoon.
The Liqhobong mine, which it has a 75% stake in, is supplied electricity from the Muela hydropower station which is currently undergoing a two month maintenance programme.
Firestone explained: "Since then, the mine experienced unexpected voltage fluctuations that caused the drives of the plant equipment to trip and as a result, operations have been severely disrupted."
The company said it is engaging with the Lesotho Electricity Co, the owner of Muela, and will provide a further update in due course.
