Glencore is in negotiations with the South African government about a pledge to invest R6-billion in the Cape Town refinery, as the company is set to miss the deadline following an explosion that shut the plant for several years. The commodities-trading giant agreed when it bought the plant to make the investment in the facility within five years, a period that ends near the end of this month. South Africa has indicated discussions over the matter are ongoing, while Glencore said it remains committed to the investment.
