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.

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 (Deposit): THIS SITE NAME WAS CREATED BY THE REPORTER OR OTHER USGS EMPLOYEE BASED ON PROXIMITY TO SOME MAJOR GEOGRAPHIC FEATURE.

Comment (Workings): A NUMBER OF SHAFTS WERE SUNK TO BEDROCK FOR DRIFT MINING. A NUMBER OF HOLES WERE ALSO SUNK FOR PROSPECTING.

Comment (Geology): CREEK APPARENTLY ON THE EAST EDGE OF MINERALIZED ZONE THAT EXTENDS SOUTHWESTWARD THROUGH DUNCAN AND FLAT CREEKS. ; MAJOR.UNITS: BEDROCK IS DARK, MICACEOUS CRENULATED SLATE-PHYLLITE WITH PYRITE.

Comment (Deposit): STREAM GRADIENT APPROXIMATELY 50 FEET PER MILE IN AREA MINED. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT

Comment (Location): USGS MF-405, LOC. 29. PLACER GROUND FROM APPROXIMATELY 1 MILE ABOVE MOUTH UPSTREAM FOR 3 MILES. COORDINATES GIVEN FOR CENTER OF MINED GROUND. LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).

Comment (Development): STAKED IN 1912, ACTIVELY PROSPECTED IN 1913. MINED 1912-1920'S AND 1933 TO ABOUT 1940. MINING BY DRIFTING. DURING THE SUMMER OF 1915 FOUR PLANTS OPERATED. CREEK LONG INACTIVE IN 1975.

Comment (Deposit): GOLD IN THE UPPER FOOT OF SOFT BEDROCK AND IN THE LOWER 3 FEET OF GRAVEL, ON WHAT APPEARS TO BE THE RIM OF AN OLD CHANNEL. GROUND AVERAGED 60 FT. IN DEPTH THROUGHOUT PART OF CREEK WORKED. THE BOTTOM LAYER CONSISTED OF 1-5 FT. OF "SOFT" BEDROCK OVERLAIN BY 3-8 FT. OF GRAVEL; THE REST IS MUCK. CREEK MINED OVER A LENGTH OF 3 MILES. SOME CASSITERITE WITH GOLD.
