We are a coal mining company located in Guizhou Province, China. Currently, we operate two underground coal mines located in the Xisongshan Coalfield in Panzhou City, Guizhou Province, China, namely Hongguo Coal Mine and Baogushan Coal Mine. We use mechanized long-wall retractive underground mining methods to mine raw coal in Hongguo Coal Mine and Baogushan Coal Mine, mainly 1/3 of coking coal. We generally wash raw coal and process it into refined coal at the Songshan Coal Washing Plant before selling coal products to customers. The coal washing process also produces by-products, namely medium coal and peat.
