Sentinal Peak

The Sentinal Peak is a silver 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.

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 = Brief reconnaissance geologic mapping and collection of a few soil and silt samples. Copper, molybdenum, zinc, and gold values were not anomalous; silver ranged between 1.3 and 1.9 ppm.

Comment (Reference): Primary Reference = Christie, 1974

Comment (Geology): Geologic Description = Christie (1974) briefly examined a 4,000 ft (1.2 km) by 3,000 ft (900 m) color anomaly developed in a basalt-andesite volcanic sequence. Rocks are generally unaltered except where pyrite content is high (about 5 percent); the typical pyrite content in the anomaly is 0.1 to 1 percent. The altered rock forms narrow (+/- 20 ft, 6 m) linear zones. Fracture-controlled pyrite apparently is confined to these altered zones. No mention is made of quartz veining. Minor quartz diorite porphyry and granodiorite were seen in float in the creek on the east side of the ridge but no intrusive rocks were seen in outcrop.

Comment (Deposit): Model Name = Epithermal gold vein?

Comment (Deposit): Other Comments = Altered area examined by W.H. White (USGS, 1990); no significant mineralization found.

Comment (Exploration): Status = Inactive

Comment (Geology): Age = Miocene or younger
