Satelite View

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.
