The Damajianshan Mine is located in Qimaba Township, Luchun County of Yunnan Province in the PRC. It is near the border between the PRC and Vietnam: (Figure 2). In the 3.67 square kilometres covered by the mining right there are JORC Ore Reserves of 7.6 million tonnes of ore with an average Cu grade of 1.46% and JORC Mineral Resources of 15.2 million tonnes with an average Cu grade of 1.68%. The mine operation has the potential to produce over 429,000 tonnes per annum for 18 years. The mine site is easily accessible by road. The road conditions may vary depending on the weather. After beneficiation, copper concentrate is trucked to customers. Please refer to Table 1 and Table 2 below for a more detailed breakdown of Ore Reserves and Mineral Resources.
