The Ladue is a lead 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 (Deposit): Other Comments = See also: Big Creek prospect (TC004).
Comment (Deposit): Model Name = Stratabound Cu-Pb-Zn volcanogenic deposit?
Comment (Workings): Workings / Exploration = In 1976, the property was explored using airborne and ground electromagnetics. An undetermined amount of soil sampling also took place (Eberlein and others, 1977, p. 101). In 1982, the property was explored again using electromagnetic surveys, soil sampling, geologic mapping, and reconnaissance geologic mapping and sampling by Noranda (Dunbier, 1982).
Comment (Geology): Geologic Description = The Ladue prospect consists of galena and sphalerite in rhyolite dikes that cross-cut amphibolite-grade, quartz-mica schist of Paleozoic and/or Precambrian age. The Ladue claims were staked in 1975 and 1976. In 1976, the property was explored using ground and airborne electromagnetic surveys. Soil sampling in 1976 indicated several zones of anomalous lead-zinc values, spatially related to good conductors (Eberlein and others, 1977, p. 101). In 1982, Noranda spent 18 field days exploring the property. They conducted electromagnetic surveys, soil geochemistry, and geologic mapping (Dunbier, 1982).? the Noranda efforts focused on the Lucy claim block as one of the most promising in the area. After the field work was finished, Noranda concluded that there were low-level anomalies of copper, lead and zinc, but that there was not a near-surface massive sulfide deposit on the Lucy claim block, although one may exist in the region (Dunbier, 1982).
