The Mary Lou 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 (Exploration): Status = Active

Comment (Geology): Age = Quaternary.

Comment (Workings): Workings / Exploration = The deposit occurs along 4,000 feet of beach. It was worked primarily during the period 1904 and 1905, when 20 to 40 men worked the deposit with rockers. Atwood (1909) estimated a production of 12,000 ounces during that time. Minor, intermittent work has taken place since.

Comment (Geology): Geologic Description = This beach gold placer deposit was discovered by Louis Herman in 1904 and described by Martin in 1905. The deposit was 4,000 feet in length and was apparently derived by erosion of nearby mineralized volcanic rocks. The gold was generally found below mid-tide, especially around boulders.? Atwood (1909) reported that 20 to 40 men were working the deposit with rockers in 1904 and that about 12,000 ounces were recovered in 1904 and 1905. Since that time there has been minor production.

Comment (Production): Production Notes = Atwood (1909) estimated that 12,000 ounces of gold were recovered in 1904 and 1905.

Comment (Reference): Primary Reference = Atwood, 1909

Comment (Deposit): Model Name = Placer Au (Cox and Singer, 1986; model 39a)
