Geologic structures

Type of structure Local
Structure description fault zone

Ore body information

  • General form roughly tabular replacement in fault zone

Controls for ore emplacement

  • fault

Comments on the geologic information

  • Host rock (Pilot Shale?) is a fine-grained sedimentary rock that is banded with iron oxide coloration, outcropping immediately above and east of the pit. Two ore dump sites are cut into this sedimentary rock, which also forms the NE wall of the pit while a light to medium gray limestone forms the SW wall of the pit. The ore zone appears to have been a pod of silicified carbonate material lying along the flat contact between the shale and limestone units. Rock in pit is maroon-brown to gray in color with black areas and is strongly fractured. Dark brown and white coarse calcite vein. Gray to purple silicified sandy limestone is cut by thin calcite veinlets. Rock is fractured with white silica coating fractures.

Comments on the workings information

  • Small open pit was worked during the summers of 1979 and 1980.

Comments on other economic factors

  • From 1979 to1980 about 15,000-20,000 tons of ore were mined grading about 2 ounces per ton, Ag. No reserve data is available.

Comments on development

  • A small open pit mine was worked during the summers of 1979 and 1980, chiefly for silver with grades running less than 2.0 ounces per ton. About 15,000-20,000 tons of ore were mined. The ore was heap-leached at Hamilton. The mine was operated by Gold Creek Corp., which operated several mines at the time in this part of Nevada.
