Hines and McLaughlin

The Hines and McLaughlin 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 (Geology): Geologic Description = The Hines and McLaughlin prospect was developed by six shafts ranging from 20 to 56 feet in depth (Cathcart, 1922, p. 236). The shafts were sunk in bedrock composed of alternating layers of marble and mineralized schist. None of the workings were open when Cathcart visited the area. He reported that the schist was mostly decomposed and stained yellow--possibly by jarosite that replaced pyrite. Little quartz was present. The material did not pan free gold, but the owners reported assays of 3 to 24 dollars in gold; they also reported the presence of platinum, which Cathcart doubted.

Comment (Workings): Workings / Exploration = Five claims on King Mountain above Dexter were explored by shallow shafts that were caved at the time of Cathcart's visit (Cathcart, 1922). The claims, including the Royal Group on King Mountain, were reported by Mertie (1918), but he did not visit them in 1916. Gold was reported by assay, but decomposed schist did not pan free gold. The validity of the prospect is doubtful.

Comment (Geology): Age = Probably about mid-Cretaceous, the age of other lode gold deposits in the Nome district.

Comment (Reference): Primary Reference = Cathcart, 1922

Comment (Deposit): Model Name = Low-sulfide replacement lode is schist and marble.

Comment (Exploration): Status = Inactive
