The Rain is a gold and silver 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.

Alterations
Alteration Type: L
Alteration Text: The volcanic rocks exhibit regional propylitization, localized silicification, and potassium flooding or secondary growth on primary feldspars. Wall rock adjacent to quartz veins has been silicified and pyritized. No argillic alteration has been recognized.

Comments
Comment (Reference): Primary Reference = Randolph and Ellis, 1989
Comment (Deposit): Model Name = Epithermal gold quartz vein?
Comment (Deposit): Other Comments = This site is on land conveyed, patented, or selected by the Aleut Native Corporation.
Comment (Workings): Workings / Exploration = In 1975 the Aleut-Quintana-Duval JV did sampling at this site as a followup of the discovery of numerous color anomalies in the area. Analyses of 18 rock samples indicated metal values of up to 200 ppm copper, 0.05 ppm gold, 36 ppm molybdenum, 2.1ppm silver, and 138 ppm zinc (Christie, 1974). Kennecott mapped and sampled this general area in 1985 (Simpson, 1985). Battle Mountain Exploration in 1989 did detailed sampling and mapping at this site. The sampling (56 rock) gave metal values of up to 67 ppm arsenic, 201 ppb gold, 125 ppb mercury, 34 ppm molybdenum, and 0.8 ppm silver (Randolph and Ellis, 1989).
Comment (Geology): Geologic Description = This site is similar in character to the Wind and Fog prospects (ARDF numbers UK007 and UK008). However, the metal values at this site are considerably lower. The site is marked by a color anomaly about 7,000 by 5,000 feet in extent. Propylitically altered Tertiary andesites overlie an argillite and diorite basement complex. The volcanic rocks exhibit quartz veining and local silicification. The quartz is usually white and contains few visible sulfides. The veins are somewhat enriched in arsenic, copper, mercury, and molybdenum and locally in gold and silver. The highest metal values obtained are: 67 ppm arsenic, 200 ppm copper, 201 ppb gold, 125 ppb mercury, 36 ppm molybdenum, 2.1ppm silver, and 138 ppm zinc (Christie, 1974; Randolph and Ellis, 1989).
Comment (Geology): Age = Late Tertiary or younger.
Comment (Exploration): Status = Inactive
