Deposit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
Deposit DOMICAL FOLDS ALSO SEEM TO AFFECT THE LOCALIZATION. CAREFUL PROSPECTING WITH ALL THESE FACTORS IN MIND PROBABLY WILL ADD TO THE ESTIMATES OF COBALT ORE IN THE AREA. (BILBREY, J.H., 1962)
