The Steeple Point is a silver and 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 (Geology): Geologic Description = This geothermal site is described by Randolph and Ellis (1989) as being similar to ARDF number UK005. The rocks consist of waterlain tuffs and lahars of Quaternary age. The site contains numerous fumaroles and hot-springs and is marked by a 7,000 by 4,000 foot color anomaly. It consists of acid-leached rocks and localized silica stockworks. Some of the fumarolic centers display strong silicification and pyritization. Hot-spring centers also exhibit silicification and calcedonic breccias. Combined metal values from 55 rock samples obtained here and at ARDF number UK005 are up to >2000 ppm arsenic, 115 ppb gold, >5 ppp mercury, 11 ppm molybdenum, and 4.4 ppm silver (Randolph and Ellis, 1989).
Comment (Deposit): Model Name = Hot-springs Au-Ag (Cox and Singer, 1986, model 25a)
Comment (Deposit): Other Comments = This site is on land conveyed, patented, or selected by the Aleut Native Corporation.
