Also known as the Nopah Mine.

From the California Journal of Mines and Geology, Vol. 47, No. 1, Jan. 1957:

4 claims are owned by J.P. Madison, Shoshone, California.

Lead and zinc minerals occur along a highly curved fault in a brecciated zone (a breccia pipe) which crosscuts the bedding of dolomitic limestone. The breccia consists of angular dolomitic limestone fragments in a greenish matrix.

The main workings consist of an 80-foot shaft inclined 80 degrees E. from an open cut, with a 75-foot adit connection from the south to the shaft collar in the cut, and levels 20 and 32 feet. On the 20-foot level, 75 feet of drift follows the curved fault for nearly 250 degrees. On the 32-foot level, 25 feet of drift follows the fault for 90 degrees. Some stoping has been done.

Five cars of ore, three of lead and two of zinc, were shipped by Madison in 1943. Madison reports the shipments averaged 30 percent lead and 30 percent zinc respectively. SIlver in the lead ore was as much as 72 ounces per ton but averaged 17 ounces per ton.

The mine is idle.
