Thermal coal prices extended gains in Shaanxi's Yulin. Online auctions by major miners saw notable WoW gains, and some smaller miners lifted offers by 5-10 yuan/t. However, stagnant portside prices dampened market sentiment. Downstream buyers shunned high-priced cargoes, combined with muted end-user demand, capping truck arrivals at mines. Moderate spot sales and no significant demand improvements would drag down prices further.
