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 (Development): 7 CLAIMS ORIGENALLY LOCATED 84 J. MELLAN. MAJOR PRODUCTION OCCURED FROM 1930-1935. SPORATIC ACTIVITY OCCURED 1936-43 AND 1955-57, SHOWING NO PRODUCTION. RECENTLY STAKED & DRILLED. IN 1983.

Comment (Deposit): CINNABAR OCCURS AS BOTRYOIDAL MASSES ALONG CONTACT BETWEEN SANDSTONE AND LIMESTONE, AND VEINLETS ARE ASSOCIATED WITH SHEAR ZONES. CRYSTALLINE CINNABAR OCCURS AS VEINLETS AND GRAINS IN SACCHROIDAL VEIN QUARTZ, AND AS BOTRYOIDAL COATINGS IN VUGS IN THE SILICIFIED VOLCANICS. THE ROCKS ARE ALSO COATED WITH CHALCEDONIC SILICA AND CONTAIN MINOR JAROSITE(?). NO OUTCROPS WERE OBSERVED ON CLAIM BLOCK WHICH IS COVERED WITH ALLUVIUM-SHAFT IS COLLARED IN ALLUVIUM. LATE STAGE COCKSCOMB QUARTZ COATS SILICEOUS ROCKS, WHICH ALSO CARRY VERY FINE BARITE CRYSTALS INTERGROWN WITH QUARTZ CRYSTALS AND VERY FINE PYRITE. SANDSTONE WAS OBSERVED ON THE DUMP, HOWEVER, NO SEDIMENTARY ROCKS OUTCROP IN THE VICINITY, ONLY VOLCANICS. DARK GREY ZONES IN SILICEOUS ROCKS SUGGEST DISSEMINATED SULFIDE MINERALIZATION. SAMPLE SITE 1471.

Comment (Workings): VERTICAL SHAFT ABOUT 100 FT DEEP, W/ ADITS ON TWO LEVELS AND SEVERAL CONECTING STOPES. AND RAISES. INCLINED SHAFT, MINOR SURFACE CUTS, REMAINS OF OLD BUILDINGS, EQUIPMENT

Comment (Deposit): THERE ARE NO MINE WORKINGS ON THE EASTERN SIDE OF THE SUMMIT AS INDICATED BY THE MINE SYMBOL ON THE MAP. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT; 3 FIELD OBSERV
