A former Pb-Ag-Zn-Au-Cu-Mn mine located in sec. 33, T19S, R42E, MDM, 0.9 km (0.6 mile) SSE of Lookout City, on the lower S slope of Lookout Mountain, along Thompson Canyon, E slope of the Argus Range (9 airline miles SE of Panamint Springs). Operated during the period 1902 to 1952. MRDS database stated accuracy for this location is 10 meters.

"The Minietta operated on and off until 1915. In 1924 this silver-lead-gold mine was reopened and the Modoc Mine was leased. [21] Their slag piles and dumps were reworked, yielding gold, silver, copper, lead, and zinc. In the mid-1930s the Minietta was leased and refinanced and a mill and modern equipment were to be installed. If gold and silver prices held, the future of the mine seemed bright. [22] By 1938 the Modoc Mine had produced $1,900,000 worth of ore and the Minietta $1,000,000." (National Park Service).

Mineralization is sphalerite ore hosted in limestone. The ore body strikes N40-45E and dips 45-22NW. Diabase dikes are in close proximity to some stopes and may have controlled deposition of ore. The ore occurs along the sole of a thrust sheet and in steeply dipping faults below the thrust. The outcrop is marked by Mn and Fe oxides. Local alteration involved silicification. Diabase is an associated rock. Local rocks include Devonian marine rocks, unit 1 (Death Valley).

Local geologic structures include faults and a thrust.

Workings include surface and underground openings with a length of 106. 68 meters and comprised of 3 levels with the upper level ore stoped. from the 85 foot drift to the surface. The middle level consists of a 65 foot adit. The lower level is a 250 foot adit.

Production data are found in: Goodwin, Joseph Grant (1957).

Production statistics: Year: 1949 (through 1949): ^16% Pb. The last ore shipped in 1952 contained 12.1% Pb, 8.2 ounces Ag/ton plus recoverable Cu & Au. Zn production has not been large, about 12,000 pounds (1948 & 1950).
