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.

Comment (Workings): CROSSCUTS, ADITS, 250 FT. DRIFT W/BACKS OF 80 FT. ON VEIN; STOPED OUT NEARLY TO SURFACE. UNDERHAND STOPED FOR 70 FT. ALONG STRIKE, AND 40 FT. ON DIP. NORTH DRIFT, 70 FT. LONG. SOUTH DRIFT, 1100 FT. LONG INTO UNION EXT. CLAIM. WINZES. 300 FT. SHAFT MILLSITE.

Comment (Deposit): VEIN, 2-6 FT. THICK, HANGING WALL BLACK SLATY SCHIST, CONTAINING CONSIDERABLE GRAPHITE, CRUSHED & BROKEN. FOOTWALL IS DECOMPOSED, LIGHT-COLORED DIKE ROCK.ON SOUTH SIDE ABOVE DRIFT, HANGING WALL, 2-3 FT. THICK, SEP. FROM FOOTWALL BY GOUGE, IN SOME INSTANCES BRECCIATED SLATE. IN NORTH DRIFT, VEIN BROKEN & NARROW AT FARE, DIP STEEPENS WHERE FOLLOWED DOWN BY WINZE. GENERAL OBSERVATIONS INDICATE THAT MOST VEINS IN AREA MAY BE SECTIONS THAT HAVE BEEN 'BENT OVER' NEARLY FLAT, AND IN CASES, BROKEN AWAY, FROM REMAINING DEEPER SECTIONS OF VEINS, ORIGINALLY MUCH STEEPER IN DIP.

Comment (Production): REPORTED PRODUCTION OF $79000 SOME YEARS PRIOR TO 1925. ORE FREE MILLING NO SPECIFIC PRODUCTION RECORD FOUND

Comment (Development): ECON.COM: ORE REMAINING PRIOR TO 1925 WAS LOW-GRADE

Comment (Geology): KLAMATH, MT. LAUREL & UNION MINES ALL ON SEGMENTS OF SOME FISSURE OR CLOSELY PARALLEL FISSURES. THEORIZED GRAVITY SLIDE 1 OF MT. MASS IN NW DIRECTION TO ACCOUNT OF HEAVY GOUGE ZONES IN VEIN(S) AND VARIABLE DIPS.
