The Chengang area is located in the nearly north-south-trending molybdenum anomaly zone from Qian＇ echong of Guangshan county to Shangqipan of Xinxian county, which shows a good molybdenum ore prospecting potential. Molybdenum-dominant anomalies in drainage sediments were delineated by a survey of regional mineral resource at a scale of 1：50,000. This paper describes the inspection results of the multiple anomalies in the Chengang area. The molybdenum anomaly discovered by the geochemical soil survey at a scale of 1：10,000 has high intensity, a large area amt （：lear con- centration centers. Examinations in trenches show very low molybdenum mineralization. In drilling holes, 4 layers of molybdenum ore bodies were found, of which the thickness and grade of the 1 st, 2nd, and 4th ore bodies meet commercial demand. The grade of the 3rd-layer ore body reaches the cutoff val- ue. These figures imply a fairly good result of ore search effort.
