More longwall moves led to a sharp decline in lean coal output recently in China's main production areas. Active downstream buying propelled coal prices. One Luliang-based coal miner in Shanxi lifted lean coal prices by 20-40 yuan/t, with high-S lean coal (A 8.5%, S 2.6%, V 17%, G 65) up to 1,060 yuan/t ex-washplant with VAT, sending the total increase to 50 yuan/t this month. Mid-S lean coal (A 8.5%, S 1.3%, V 18%, G 70) rose to 1,350 yuan/t, taking the aggregate increase to 40 yuan/t this month.
