Statistical investigation of the distribution of copper lodes in the Singhbhum Shear Zone in relation to several geologic factors indicates that the structure is the guiding control in locating ore deposits. Application of Spearman's coefficient of rank correlation by considering all available geologic factors against the distribution of lodes known in 1937, helps in locating favorable areas of significant positive correlation. The favorable areas for copper exploration are 2 to 4 km south of the line of appearance of slip-transposition schistosites in the eastern sector and 1 to 3 km south of the northern shear plane in the western sector. The validity of the analysis is supported by the occurrence of all the present-day mining-exploration sites within the suggested favorable area. Similar statistical analysis may help in locating favorable exploration sites in other areas of mineralization and can be utilized as an added tool in exploration programs. © 1965 Society of Economic Geologsits, Inc.
