Mother

The Mother 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 (Deposit): Model Name = Schist-hosted gold-quartz vein

Comment (Geology): Geologic Description = Brecciated, iron-stained quartz and silicified schist assayed $0.46 gold per ton (0.022 ounce of gold per ton) (Hill, 1933, p. 122). At the creek level, the vein structure is approximately 20 feet wide. In a cut near the top of the ridge a quarter of a mile east of the creek, a vein consisted of 10 feet of quartz breccia on the north wall and 10 feet of bluish clay with quartz fragments above the south wall. The quartz next to the north wall showed evidence of mineralization and was reported to average $20 of gold per ton (0.97 ounce of gold per ton) in a small area where the upper work was being done (Hill, 1933, p. 122). The clay and quartz carried only a few cents in gold per ton. Some pieces of high-grade quartz with free gold were noted (Hill, 1933, p. 122).

Comment (Reference): Primary Reference = Hill, 1933

Comment (Workings): Workings / Exploration = By 1931, development at this prospect included several open cuts and three tunnels; one was near the creek level and two were near the crest of the ridge to the east. All were caved at the time of Hill's visit (Hill, 1933, p. 121).

Comment (Exploration): Status = Inactive
