Disseminated gold
Commodity: Ore Materials: gold
Deposit type: Sediment-hosted Au
Development: The deposit was reportedly still in exploration phase in 1987. The topo map shows extensive drill roads, surface exploration trenching and 2 open pit mines on the Ratto Canyon side of Pinnacle Peak and Lookout Mountain in the vicinity of the probable deposit. Staccato website (2004) reports that ?Recent production (1970-1985) consists of 30,000-40,000 ounces Au produced from the adjacent Windfall Mine and the Ratto Canyon/Lookout Mountain Pits. ?

Regional Geology
This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.

Quaternary - Miocene 0 - 23.03 Ma ID: 3185380 | Cenozoic sedimentary rocks Age: Cenozoic (0 - 23.03 Ma) Lithology: Sedimentary rocks Reference: Chorlton, L.B. Generalized geology of the world: bedrock domains and major faults in GIS format: a small-scale world geology map with an extended geological attribute database. doi: 10.4095/223767. Geological Survey of Canada, Open File 5529. [154] |
Late Devonian - Middle Devonian 358.9 - 393.3 Ma ID: 2863843 | Carbonate Shelf Sequence - Limestone and minor dolomite Age: Devonian (358.9 - 393.3 Ma) Stratigraphic Name: Devils Gate Limestone; Guilmette Formation; Sultan Limestone Description: Includes generally cliff-forming, thin- to thick-bedded limestone. These rocks are mainly shallow water subtidal, intertidal, and supratidal deposits formed on a broad inner carbonate shelf (Stewart, 1980). The Devils Gate Limestone and Guilmette Formation in northern Nevada are the principal units, and the Sultan Limestone is included from the southern part of the State. Unit is overlain (usually disconformably) by the Pilot Shale of unit MDcl except in southernmost Nevada where it is overlain by Mississippian carbonate (Mc). It depositionally overlies Middle and Lower Devonian unit Dcd. In a few places, such as southern Nevada and parts of Eureka County, regional mapping did not distinguish the Upper and Middle Devonian section from the Lower Devonian section, and all of the Devonian is included in unit Dc. Rocks mapped as the Simonson Dolomite would fit into this depositional sequence (sequences 9 and 10 of Cook and Corboy, 2004), but they are not differentiated from the underlying dolomites in White Pine or Elko Counties, so they are all included in unit Dcd here, not unit Dc. This unit crops out in Clark, Elko, Eureka, Lander, Lincoln, Nye, and White Pine Counties.
