A former surface and underground Ag-Pb-Zn-Au-Cu-Th-U-Mo mine on a patented claim located in the SE¼ sec. 17, T.14N, R.9W. (Bagdad 15 minute topo map), along the south end of the Mountain Spring fault, a little more than 3 miles SSW of Bagdad and less than 1 mile ENE of the Old Dick mine. Owned by M.L. Lynch and J.W. Lawler in 1945. Produced 1941-1951.
Mineralization is comprised of several parallel, interlacing and branching quartz veins that contain sulfides. These veins average about 1 foot or less in width, but a maximum width of 3 feet was observed. The veins all dip steeply and one can be traced for about 1,500 feet. The veins were formed along the Mountain Spring fault and are bordered by Hillside Mica Schist and Lawler Peak Granite to the east and by the Bridle Formation to the west. In the shaft the vein consists of a series of parallel quartz and sulfide stringers separated by sericite schist. Later faulting has pulverized the vein material in places. The oxidized part of the veins ranges from 1 to 50 feet. Ore control was faulting and shearing. Ore concentration was oxidation at near surface. No alteration noted.
Area structures include veins parallel to dikes and foliation; and the Mountain Spring Fault. Foliation in metavolcanic rocks trends N10E to N40E.
Workings consist of 2 shafts, each about 45 feet deep, and several cuts and pits. Total production to circa 1950 amounted to 14,405 lbs. Pb, 510 lbs. Cu and 560 oz. Ag, having a total value of $1,396 (period values).
