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): Discovery Year: 1913-1914

Comment (Deposit): GOLD ON OR IN UPPER 6 IN. OF BEDROCK OR ON CLAY FALSE BEDROCK A SHORT DISTANCE ABOVE THE TRUE BEDROCK. GOLD IN NARROW, IRREGULAR PATCHES AND STREAKS OVER A WIDTH OF AS MUCH AS 1,000 FT. ONE SHAFT SHOWED A DEPTH OF 55 FT. TO BEDROCK, OF WHICH THE UPPER 37 FEET WAS MUCK AND THE LOWER 18 FEET GRAVEL; ALLUVIUM SOLIDLY FROZEN. ELSEWHERE, 2-30 FT. OF GRAVEL BENEATH 40-50 FEET OF MUCK. FURTHEST DOWNSTREAM PLACERS CONTAIN RUSTY AND OXIDIZED GRAVEL; THOUGHT TO REPRESENT AN OLD CHANNEL OF TIMBER CREEK.

Comment (Deposit): STREAM GRADIENT APPROXIMATELY 100 FEET PER MILE IN LOWER MILE OF CREEK; ABRUPT STEEPENING IN HEADWATER SECTION. CREEK OFTEN CONFUSED WITH ANOTHER FLAT CREEK, WHICH IS A TRIBUTARY OF LONG CR. IN RUBY B-6. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT

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

Comment (Commodity): GROUND RAN $.50-$4 PER FT.2 (GOLD AT $20.67) OF BEDROCK.

Comment (Location): USGS MF-405, LOC. 34. MINE AND TAILINGS MARKED ON RUBY (A-6); TRIBUTARY OF TIMBER CREEK. UPPERMOST WORKINGS 1/4 MI. FROM HEAD, PLACERS EXTEND DOWNSTREAM FOR APPROXIMATELY 1.5 MILES. LAND STATUS VALUE CALCULATED 6-94 USING GIS OVERLAY ANALYSIS WITH BLM 1:2,500,000 SCALE OWNERSHIP STATUS MAP (1991).
