1:50,000 stream sediment survey in Hoos Braque area revealed distribution patterns, enrichment and dispersion regularity of the major ore-forming elements in this area. On the basis of analysis of regional metallogenic conditions, the Hs46b₂ composite anomaly was preferentially picked out for geological integrated prospecting, and a new medium-sized karst breccia type lead-zinc deposit was found in northern Qiongqia Te area. The newly-discovered deposit is helpful to the prospecting for the same type of deposits in carbonate formations along foreland thrust-fold belts in southwest Tianshan Mountains.
