Jiama Copper Gold Polymetallic Mine
The Jiama project is one of the largest copper gold polymetallic mines in China. The Jiama project is located within the Gangdise Copper Metallogeny Belt in Central Tibet, China and is approximately 60 kilometers east of Lhasa City along the Sichuan-Tibet Highway. The Jiama project is a large scale polymetallic deposit consisting of copper, molybdenum, gold, silver, lead and zinc.
The Company acquired the Jiama project on December 1, 2010 concurrent with the closing of its initial public offering and listing on the Stock Exchange of Hong Kong Limited. Commercial production began at the Jiama project in September 2010.
Phase I development was completed at the Jiama project in 2010 and included two open pits, a processing plant and an underground ore transportation system.
Phase II expansion started commercial production on July 1, 2018. Jiama Mine’s Phase II consists of two series, Series I and Series II, each having a mineral processing capacity of 22,000 tpd. The full design capacity of ore processing at Jiama Mine will increase to 50,000 tpd from the previous capacity of 28,000 tpd once Series II reaches full design capacity.
The copper production in 2022 is approximately 187 million pounds (approximately 85,000 tonnes) which was in line with the 2022 production guidance range.
