South Africa's state-run power utility Eskom said on Monday that it was in talks with the business rescue practitioners working to save the Optimum coal mine and was considering a proposal to reduce the volumes of coal it takes from the mine.

"Eskom is currently considering the business rescue practitioners' proposal to reduce the monthly coal supply tonnage from 400,000 to 200,000 tonnes for the remainder of the contract period given the precarious financial position of Optimum coal mine," Eskom said in a statement.
