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 (Commodity): MINERALIZATION CONSISTS ESSENTIALLY OF BEMENTITE AND NEOTOCITE WITH SMALL AMOUNTS OF OTHER MINERALS.

Comment (Deposit): A HIGHLY SILICEOUS MANGANIFEROUS LENS OCCURS IN AN ALTERED BASALT. THE LENS HAS A MAXIMUM THICKNESS NEAR THE CENTER IS 30 FT AND THINS TOWARD THE EDGES.

Comment (Workings): OPEN CUT

Comment (Geology): LIMESTONE, WHICH IS USUALLY PRESENT IN DEPOSITS OF THIS TYPE IN THE AREA, DOES NOT OCCUR IN SIGNIFICANT QUANTITIES.

Comment (Development): TWO DIAMOND-DRILL HOLES WERE DRILLED BY THE U.S. BUREAU OF MINES IN 1955 TO DETERMINE EXTENT OF THE LENS. THESE INDICATED THAT THE LENS PINCHES AT DEPTH AND TO THE WEST.

Comment (Production): PRODUCTION CONSISTED OF TEST SHIPMENTS ONLY. MECHANICAL CONCENTRATION TESTS FAILED TO PRODUCE SATISFACTORY RESULTS EITHER IN PERCENTAGE RECOVERY OR GRADE OF CONCENTRATE. SMELTING WAS MUCH MORE SUCCESSFUL; 92.5% OF THE MN WAS RECOVERED IN AN ALLOY CONTAINING 38.3% MN, 39.7% FE, AND 13.3% SIO2.

Comment (Location): ACCESS TO CLAIM IS BY WAY OF QUINAULT RIDGE ROAD NORTHEASTERLY ABOUT 1.75 MI TO AN UNMARKED ROAD JUNCTION; FROM THE JUNCTION, THE EASTERLY BRANCH EXTENDS 1 MI TO THE WORKINGS.
