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.

Land ownership: BLM Administrative Area
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments

Comment (Location): LOCATION GIVEN IS CONFLUENCE OF ARCHIBALD GULCH AND NOLAN CREEK; RECENT MINING HAS CONCENTRATED ON BENCHES AT MOUTH OF ARCHIBALD GULCH LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).

Comment (Development): MINING: 1903-1909, 1927, 1933-39, 1974, AND 1984; 20 UNPATENTED PLACER CLAIMS

Comment (Workings): CREEK AND BENCH PLACERS BY HAND AND HYDRAULIC METHODS; DRIFT MINING IN BURIED CHANNEL; GRAVEL FROZEN

Comment (Geology): GRAVELS IN BOTH THE MODERN STREAM AND OLD CHANNEL DEPOSITS ARE COARSE AND SUBANGULAR; NUMEROUS BOULDERS IN STREAM GRAVELS; BOULDERS RARE IN CHANNEL DEPOSIT ; MAJOR.UNITS: SCHIST BEDROCK
