Gold Found In Calcite Rock.

Custer, S. D., Special: Gold has been found in limestone ten miles west of Custer. Assays show the ore to run irom sl6 to $175 to the ton. During the last six weeks about 200 assays have been made from ores of the limestone. In every instance gold was found from a trace to $9 a ton. There are at least 2,000 square miles of limestone exposed in the Black Hills. Gold is found so seldom in alkaline earths that this deposit is a great curiosity to mineralogists. Gold is usual in siliceous or volcanic rocks.
