RI 4497 Investigation Of Idol And Dalton Zinc Deposits, Grainger County, Tenn.

The Idol zinc prospect, formerly known as the Comstock, was examined by Harold B. Ewoldt, a Bureau of Mines' engineer, accompanied by Deane F. Kent of the United States Geological Survey on July 22, 1943. Previous to that time, the Geological Survey had contoured and studied the area. As a part of the war minerals program, further investigation of the area was recommended. The Dalton property, a mile and a half northeast of the Idol property, was examined during the progress of the work at the Idol, and it was decided to include this property also in the project. From February 7, 1944, to May 16, 1944, six holes totaling 2,739 feet were diamond-drilled on the Idol property and eight holes totaling 1,850 feet were diamond-drilled, and three pits channel sampled on the Dalton property. The drilling showed sphalerite to be sparsely distributed through a 100 foot thickness of the Kingsport member of the Knox dolomite.
