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. The Jiama project will be developed into a combined open-pit and underground mining operation. 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. Trial production began in July 2010 and commercial production began in September 2010. The Jiama mine is processing 6,000 tonnes of ore per day. Phase II development at the Jiama project will include a major mine expansion and work on an updated feasibility study including a mine plan and reserve update is ongoing.

Resource Estimate

The 2010 drill program was completed at the Jiama project in December 2010 with 76 holes drilled totaling 45,537 meters. The 2010 drill program defined and upgraded a significant amount of Jiama's inferred resources to measured and indicated resources. Total measured and indicated resources increased by 443% from 185.1 million tonnes averaging 0.74 percent copper and containing 1.38 million tonnes of copper to 1,006.0 million tonnes averaging 0.41 percent copper and containing 4.08 million tonnes of copper.

The resources for the Jiama project as of June 2011 are summarized in tables 1.1 and 1.2.
