The Vent is a gold mine located in Alaska.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.
Mine Info
Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Workings): Workings / Exploration = In 1988 Battle Mountain Exploration Company examined the occurrence and collected 12 rock and 12 pan samples. Only one sample contained detectable gold (0.44 ppm), as reported by Ellis (1988).
Comment (Geology): Geologic Description = At this site two dome-shaped bodies of porphyritic, pyrite-bearing, andesite crop out in an area mapped as Eocene to Oligocene Popof volcanic rocks (Wilson and others, 1995). The domes exhibit sheeted jointing and are accompanied by radiating dikes. Ellis (1988) suggests that they occur on the side of a vent complex. Of 12 rock samples, only one contained gold (0.44 ppm). The sample also contained 202 ppm arsenic, and 0.88 ppm mercury. Most of the samples contained anomalous mercury. A few pan samples contained weakly anomalous gold (0.11 to 0.38 ppm) and mercury (0.195 to 1.35 ppm).
Comment (Deposit): Other Comments = This site is located on land patented by, or interim-conveyed to, the Aleut Corporation.
Comment (Geology): Age = Eocene or younger.
Comment (Reference): Primary Reference = Ellis, 1988
Comment (Exploration): Status = Inactive
