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 (Deposit): MINERALIZED ZONE STRIKES NEARLY E-W, DIPPING 70 N AT WEST END TO ABOUT VERTICAL AT EAST END. MINERALIZATION OCCURS IN FAULT BRECCIA, WHICH PANS GOLD FREELY, CONCENTRATED IN NARROW CLAY SEAMS THROUGHOUT THE FAULT BRECCIA MATERIAL. HIGH-GRADE ORE DISCOVERY REPORTED IN 1933: RUNNING 7.28 02/+ AU AND 9.27 02/+ AG FROM A GRAB SAMPLE OF SELECTED ORE. ORE WAS REPORTED TO HAVE GIVEN OUT IN 1947. SOME ORE OCCURRED AT INTERSECTION OF THE MAIN ZONE WITH A LITTLE N-S FISSURE WITH A LOW DIP TO THE WEST. ORE WAS ON FOOTWALL OF THE MINOR FISSURE.

Comment (Workings): SHAFTS, ADITS AND PROSPECTS; SIZEABLE UNDERGROUND WORKINGS. SEVERAL OPEN STOPES FOLLOW VEINS TO THE SURFACE. ONE STOPE ABOVE THE MILL SITE ROLLS OVER NEAR THE SURFACE, AFTER DIPPING CLOSE TO 60 SW

Comment (Commodity): 2 KINDS OF GOLD: GOLD FROM CLAY SEAMS IS DARKER (WITH ANOXIDE COATING) THAN GOLD FROM MASSIVE RHYOLITE

Comment (Location): ACCESSIBLE BY GOOD UNIMPROVED ROAD 2 MILES NORTH OF ROSEBUD CANYON. . INFO FROM LAND.ST :(1972)

Comment (Development): NOT ACTIVE AT TIME OF EXAMINATION IN 1984. DISCOVERED IN 1906 WITH BIG BOOM TILL 1908, WHICH RAPIDLY DISSIPATED. MILL BUILT IN 1930'S BY AMERICAN MINING AND MILLING CO (50 TPD). THAT COMPANY FOLDED AND THE MILL WAS DISMANTLED AND SOLD.
