McCarty shaft

The McCarty shaft 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Comment (Reference): Primary Reference = W.J. McCarty, unpublished report, 1932

Comment (Deposit): Model Name = Gold-quartz vein.

Comment (Exploration): Status = Inactive

Comment (Geology): Geologic Description = The McCarty vein varies from a few inches to five feet wide at this location. The vein strikes N 70 W and dips 65 SW. It has been traced for 1200 feet and ore from the surface pits along the full extent of this distance has been found to carry gold. There has been considerable shearing along the vein walls and several small faults have been encountered. The vein filling is a milky quartz but often contains impregnations of arsenopyrite (W.J. McCarty, unpublished report, 1932). By 1930, the McCarty shaft was 60 feet deep along the south dipping McCarty shear zone (Stewart, 1931). A drift from the 60-foot level of the shaft extended 135 feet east and 369 feet west. Two raises had been driven to the surface from the 60-foot level, one at the 135-foot station in the east drift and one at the 284-foot station of the west drift. All mill grade ore had been stoped from above the 60-foot level and the shaft was being deepened to the 200-foot level in 1930. Stoping from the 60-foot level produced a little over 1200 tons of ore. This ore was milled at the McCarty mine downslope from the McCarty shaft. Shaft sinking at the McCarty shaft continued in 1932 with the intent to deepen the shaft from 80 to 150 feet and drive production drifts at that level (Pilgrim, 1933).

Comment (Workings): Workings / Exploration = By 1930, the McCarty shaft was 60 feet deep along the dip of the 65 degree south-dipping McCarty shear zone (Stewart, 1931). A drift from the 60-foot level extended 135 feet east and 369 feet west of the shaft. Two raises had been driven to the surface from the 60-foot level, one at the 135-foot station in the east drift and one at the 284-foot station of the west drift. All mill grade ore had been stoped from above the 60-foot level and the shaft was being deepened to the 200-foot level in 1930.
