Köppen climate type:
A former Pb-Cu-Mn-Ag-Au mine located in sec. 33, T19S, R42E, MDM, 0.9 km (0.6 mile) ESE of Lookout City, on Lookout Mountain (8½ air miles SE of Panamint Springs). MRDS database stated accuracy for this location is 10 meters.
Mineralization is hosted in limestone. ORE OCCURS IN FISSURES ADJACENT TO DIABASE DIKES AND SILLS. Associated rocks include diabase. Local rocks include Devonian marine rocks, unit 1 (Death Valley).
Workings include underground openings comprised of tunnels and shafts. The lower tunnel, driven SW for 1,800 feet has 2,000 feet of drifts. Tunnel No. 1 connected to tunnel No. 2 by a 560 foot raise. Tunnel No. 2 was driven SE for 500 feet, and has 1,200 feet of crosscuts and drifts. No. 3 tunnel is 600 feet driven S. The Modoc (No. 3) shaft is 600 feet deep with an inclined shaft of 200 feet.
Production data are found in: Goodwin, J. C. (1957): 491.
Since 1944 15,000 tons of dump materials have been shipped. Assays ran 2.37% to 11.07% Pb, 4 to 10% Zn, 0.45 to 12.83 ounces Ag and 0.03 to 0.12 ounces Au per ton.
Production statistics: Year: 1890: Ore: ^30 to 50% Pb, 50 to 200 ounces (3,529 grams) Ag and 0.25 ounces (7 grams) Au/ton.
