Reference information

Comments Exploratory drilling and trenching define metal reserve >500,000 tons Cu (with a mean grade of 0.91% Cu); 20,000 tons Mo (with a mean grade of 0.06% Mo), and 30 tons Au (with a mean grade of 0.98g/t Au) according to Jian and others (2007). 2.84 g/t Ag (Singer and others, 2008). Classification in dispute. Jian and others (2007) describe as early VMS characterized by banded Cu-bearing pyrite ores with superimposed Silruian (?) porphyry Cu. Li, Lai and others (2007) and Li, Chen and others (2008) suggest it's an orogenic copper deposit.
