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 (Location): SW PART OF SEC. 33; ON NW FLANK OF VOLCANO PEAK

Comment (Production): AS OF 1961 THE MINE WAS STILL PRODUCING SMALL QUANTITIES OF ORE, AMOUNT UNKNOWN.

Comment (Workings): OPEN PIT OVER IRON DEPOSIT. TWO ADITS, 16 AND 130 FEET IN LENGTH AND A 20 FT. TRENCH 10 FEET DEEP ON TUNGSTEN DEPOSIT.

Comment (Deposit): HARD, DENSE HEMATITE OCCURS IN REPLACEMENT BODIES AND SMALL VEINS IN DOLOMITE; MAXIMUM EXTENT OF DEPOSITS 1,000 FEET BY SEVERAL HUNDRED FEET. ADJACENT TO GRANITIC ROCK IS TACTITE ZONE 3 TO 6 FEET WIDE CONTAINING SCHEELITE.

Comment (Deposit): IN 1951 THE PROPERTY WAS LEASED TO MARK M. BUTLER WHO SUBLEASED IT TO A. W. JENSEN AND G. W. LOTT. ; INFO.SRC : 1 PUB LIT

Comment (Geology): NEAR THE IRON DEPOSIT THE DOLOMITE STRIKES N50E AND DIPS 60NW. IT IS COMPLEXLY FOLDED AND FAULTED. THE ROCKS HAVE BEEN CUT AND METAMORPHOSED BY GRANITIC ROCKS, THE NEAREST EXPOSURE LESS THAN 300 FEET FROM THE DEPOSIT. THE IRON ORE IS BELIEVED TO BE RELATED TO THE GRANITIC ROCKS. ADJACENT TO THE GRANITIC CONTACT, THE LIMESTONE HAS BEEN ALTERED TO A NARROW ZONE OF TACTITE EXPOSED IN OUTCROP FOR DISTANCE OF 400 FEET. IN THIS ALTERED ZONE SCHEELITE MINERALIZATION OCCURS ASSOCIATED WITH GARNET, EPIDOTE, QUARTZ, AND MINOR PYRITE FINELY DISSEMINATED IN SHOOTS 3 TO 6 FEET WIDE AT MINOR FAULT INTERSECTIONS.
