Coal and coke producer New World Resources was a heavy faller after warning that as a result of recent declines in energy demand and broader market conditions, thermal coal inventories have been above the historical average levels. These conditions are likely to create pricing volatility and continued downwards pressure on thermal coal prices in the near term, it said. Imagination Technologies Group also fell after Goldman Sachs cut the stock from its 'conviction buy' list, with its target price still at 600p. Centamin, the Egyptian gold miner, rose after the country's Petroleum Minister lent his support to the company in comments made Friday.
