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 (Production): 8500 TONS OF 20-42% MN ORE, 1942-45.
Comment (Deposit): ORE OCCURS IN STREAKS 1.5-4.0 FT WIDE AND IS MIXED WITH BRECCIATED WALL ROCK.
Comment (Workings): SEVERAL OPEN CUTS AND SHORT TUNNELS, TWO PRINCIPAL AREAS: TUNNEL DRIVEN SOUTH 350 FT WITH A 150 FT WINZE AT PORTAL, THE OTHER AREA IS AN UNDERHAND STOPE 125 FT LONG, 6-20 FT WIDE.
Comment (Geology): AT BOTTOM OF STOPING, ORE IS CUT OFF, NEAR THIS POINT ORE IS SURROUNDED BY CLAY NODULES, SUGGESTING A FAULT. ; GEOL.DESC: COUNTRY ROCK OF TERTIARY VOLCANIC FLOWS AND FRAGMENTAL ROCKS ARE CUT BY FISSURES THAT TREND APPROXIMATELY NORTH AND DIP STEEPLY W. IN PLACES THE VOLCANIC ROCKS ARE BRECCIATED FOR A SHORT DISTANCE ON THE SIDES OF THE FISSURES. SEVERAL SETS OF FISSURES ARE PRESENT, ONE EXTENDS FOR 4000 FT. ACROSS THE AREA. ORE IS FOUND IN SHOOTS UP TO 400 FT. IN LENGTH AND 5 FT. IN WIDTH. ORE OCCURS IN WELL DEFINED VEINS CUTTING QUARTZ PORPHYRY, AND CONSISTS MAINLY OF MASSIVE PSILOMELANE, SOME PYROLUSITE, CALCITE AND ROCK FRAGMENTS.
