Cover Story：Exploration site at the south Tiegelong(Rongna) Cu(Au) deposit in the Duolong ore concentrating area, Tibet. Based on geological characteristics and typical mineral assemblage, researchers have deter-mined that south Tiegelong Cu(Au) deposit is the first high-sulfur epithermal deposit discovered in Tibet. Drill hole ZK3204 controlled orebody thickness of 914.77 m, copper average grade of 0.62%. Detailed investigation has controlled over 5000 thousand ton of copper resources and more than 50 ton of gold resources, suggesting that the ore deposit is the second superlarge ‘Zijinshan style’ Cu(Au) deposit in China’s mainland with important guiding significance for regional ore-prospecting and mineral resources development. The research achievement led by Professor TANG Ju-xing, Institute of Mineral Resources, Chinese Academy of Geological Sciences, ranks the third among “Top Ten Scientific and Technological Progresses of CAGS in 2013”.
