The occurrence of zinc ores in Ten- nessee was first described in the Seventh Geological Report by Gerard T roost in 1844. The first mine opened for zinc was at Mossy Creek (now Jefferson City). In 1854, A. W. Daby leased 400 acres from B. M. Branner and began open-pit mining of zinc silicates and carbonate to be used for making zinc oxide pigment.
