We currently operate four underground mines, namely Dahongshan Mining Area, Guangji Mining Area, Muma Mining Area and Yuegou Mining Area, where solution mining are employed.
As of February 2009, there was a total of approximately 57.2 million tonnes of proved and probable thenardite reserves pursuant to the JORC Code, in the mining areas mentioned above except Yuegou Mining Area. According to JT Boyd, our mining reserves are generally higher than the average purity in Sichuan Province and the rest of China. Furthermore, both Dahongshan and Guangji Mining Areas contain calcium-based glauberite ore, which is considered to be the most suitable for specialty thenardite production due to its chemical property.
As of the Latest Practicable Date, we had four thenardite production facilities with a combined production capacity of 2.2 million tpa in our four Mining Areas.
