Kingsgate and its' Thai subsidiary, Akara Mining Limited, operate the Chatree gold mine in central Thailand, 280km north of Bangkok. Chatree, Thailand's first modern gold mine, commenced operations in November 2001 with a processing plant capacity of 1 million tonnes per annum (mtpa) which was expanded to 2mtpa in 2006. Open cut, bulk mining extracts low-grade gold bearing ore, containing 1-2 grams of gold per tonne of mineralised ore, using simple drill, blast and excavate mining methods. The ore is transported to the nearby "Carbon in Pulp" (CIP) processing plant where it is crushed into a fine powder in the plant's grinding circuit. Water and reagents, including a weak cyanide solution, and activated carbon are added to extract most of the gold and silver which is poured into "doré" (gold + silver) bars and later purified in Hong Kong for the international market.
