Coal Quality Characteristics
The three coal mines of the Group are located within the Lishi-Liulin mining area of Hedong coalfield, one of the geological belts rich in premium hard coking coal in China. The coking coal in Lishi-Liulin mining area is honoured as "panda coal" or "industrial monosodium glutamate" due to its scarcity and high economic value. The Group’s coking coal is of excellent quality due to its high calorific value and caking index and low ash and sulphur, characteristics that are highly desirable for producing high quality coke.
The following is a summary of the coal quality characteristics of the Group’s three coal mines :
