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 (Commodity): ORE IS ESSENTIALLY HEMATITE INTERLOCKED WITH PYROLUSITE AND MINOR AMOUNTS OF PSILOMELANE. MIGHT BE USED AS SPIEGELEISEN ORE. UNTREATED ORE CONTAINS 18.5 TO 19.9 PCT MN, 35.8 TO 38.2 PCT. FE, 0.05 PCT. P.

Comment (Production): ORE PRODUCED WAS USED FOR FERTILIZER AND SOIL BUILDER. SEE "GEN".

Comment (Development): ITEM 1: OTHER IS METALLURGICAL TESTING ; ECON.COM: ACCESS NOT GOOD. LAST 3 MILES ON JEEP TRAIL WITH STEEP GRADES AND SANDY WASHES.

Comment (Deposit): RESULTS OF U.S. BUREAU MINES ORE DRESSING TESTS SHOWED NO APPRECIABLE LIBERATION OF IRON OXIDES COULD BE MADE IN FEASIBLE GRINDING RANGES BECAUSE OF COMPLEX ASSOCIATION OF MANGANESE AND IRON OXIDES. THUS TABLING, MN FLOTATION AND MAGNETIC SEPARATION PRODUCE NO MARKETABLE MN. HOWEVER, ORE WHICH CONTAINS 19.9 PCT. MN AND 35.8 PCT. FE IS VERY LOW IN OBJECTIONABLE IMPURITIES AND MIGHT BE MARKETABLE AS SPIEGELEISEN ORE. ; INFO.SRC : 1 PUB LIT
