The Andrew Lake is a zinc, gold, and copper 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 = A single sample of the sandstone collected during brief U.S. Geological Survey reconnaissance studies in 1993 yielded 120 ppm Cu, 110 ppm Zn, and 4 ppb Au. Volcanic rock samples yielded 4 ppb Au (93TL 102c) and up to 120 ppm Zn (samples 93AWs 12 and 13).
Comment (Geology): Geologic Description = Fine-grained lithic sandstone of the Andrew Lake Formation overlies volcanic breccia and massive flows(?). A linear, possibly a fault, extends northeast (about N 20xE) from the locality. Other samples of volcanic rocks collected in the vicinity of this linear were also weakly anomalous in Zn and Au.
Comment (Exploration): Status = Inactive
Comment (Geology): Age = Tertiary
