The Anna Mary 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 (Geology): Geologic Description = The discovery on the Mary claims was explored in 1931 and consisted of a N 70 W, 70 SW shear zone which averaged 4 to 8 feet wide. The hanging wall consists of 1 to 6 feet of crushed quartz while the footwall is 1 to 2 feet of blue clay-rich gouge (Hill, 1933). Iron oxide staining was present on some quartz, and arsenopyrite, and argentiferous galena had been identified on the prospect. A sample collected by Hill (1933) across 5 feet at the bottom of a 15 foot shaft averaged $0.46 of gold per ton (0.02 ounces of gold per ton). The Anna prospect was one hundred feet south and uphill from the Mary but had not been exposed to any degree in 1931. By 1931, the shaft on the Mary prospect had been sunk to a depth of 25 feet but had caved when visited by Stewart (1933) and Pilgrim (1932). Dump samples contained galena, arsenopyrite and stibnite with moderate gold. No production records are available from this shaft. The prospect was purchased by George Warmbold in 1938 and several pits and trenches were dug in late 1938 in an attempt to trace the shear zone.
