Comments on the geologic information

  • Geologic Description = White quartz veins along a zone at least 1000 feet long cut pyritic, rusty-weathering, light-greenish gray calcareous metarhyolite that is probably part of the Triassic Hyd Group. The metarhyolite is intruded by Mesozoic epidote-hornblende gabbro and fresh, medium-grained Cretaceous diorite (Brew, 1997 [OF 97-156-J]). The quartz veins contain sparse to rare disseminated pyrite, and rare grains of chalcopyrite, galena, and sphalerite. Gold values uncertain but probably low; the best assay from several samples collected by the USGS on the dump in the early 80's was 0.05 ounces of gold per ton (Grybeck, Berg, and Karl, 1984). Roehm (1945 [IR 195-37]) noted that the deposit had low Ag and Au values.

Comments on the production information

  • Production Notes = No documented production. There have been persistent rumors of at least a small test ore shipment that was processed nearby at the Helen S mill in the early part of the century.

Comments on the reserve resource information

  • Reserves = None

Comments on the workings information

  • Workings / Exploration = Known since before 1905 and explored by about 500 feet of underground workings from an adit (Wright and Wright, 1908). Moderate-sized dump on property. Roehm (1945 [IR 195-37]) noted that the property consisted of two parallel veins along a brecciated shear zone; levels at 63 and 134 feet were developed through a shaft. The dump is overgrown by trees and there has probably been no underground work of any significance since before WWII. However, the property has repeatedly been visited by geologists over the last several decades in conjunction with the general high level of interest in Woewodski Island, and probably has had considerable surface geologic, geochemical, and geophysical work in the vicinity, if not at this particular deposit.
