Land Status

Land ownership: BLM Administrative Area
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property.

Comments

Comment (Deposit): Discovery Year: 1981 (PRESENT CLAIMS)

Comment (Deposit): 20 FT N OF SHAFT IS A PROMINENT RESISTANT RIB OF FINELY CRYSTALLINE PINKISH-WHITE QUARTZ VEIN AND QUARTZ-CEMENTED VOLCANIC BRECCIA. THE OUTCROP UNDERLIES THE E-W RIDGELINE, STRIKING N70W, DIPPING 55 SW. BELOW THE CREST OF THE RESISTANT OUTCROP, THE VEIN CARRIES BRECCIA FRAGMENTS OF ALTERED RHYOLITIC VOLCANIC ROCKS AND POSSIBLY ALSO SEDIMENTARY CONGLUMERATE. FRAGMENTS SEEM TO INCREASE WITH DEPTH (I.E. TOWARD LOWER CONTACT WITH VOLCANICS. IRON OXIDES ARE DEPOSITED ALONG BRECCIATED CRACKS, CREVICES AND VUGS IN THE VEIN MATERIAL. DRUSY QUARTZ LINES VUGS AND GHOSTS AFTER PYRITE ARE COMMON. SOME OF THE OUTCROP CONTAINS QUARTZ PHENOCRYSTS, SUGGESTING THAT THIS IS ACTUALLY AN APLITIC DIKE. VERY MINUTE SPECKS OF SULFIDES OR FE-MN OXIDES OCCUR IN MATRIX OF VEIN MATERIAL. SOME UNUSUAL BRIGHT RED OXIDES MAY BE AFTER HG MINERALS, OR POSSIBLY JUST HYDRATED FE. SOME CHALCEDONIC BANDING AND FINE BRECCIA ZONES CUT ACROSS OUTCROP. VERY FINE-GRAINED PYRITE (OXIDIZED) OCCURS IN THE PINK RHYOLITE BRECCIA

Comment (Location): AREA UNSURVEYED ; INFO FROM LAND.ST :(1972)

Comment (Commodity): AU ORE MINERAL NOT GIVEN IN LITERATURE

Comment (Development): NO ACTIVITY EXCEPT STAKING IN 1983.

Comment (Deposit): FRAGMENTS ALSO. EXPOSED WIDTH OF OUTCROP IS PROBABLY OVER 10 FT.

Comment (Workings): VERTICAL SHAFT

Comment (Geology): 12 FOOT QUARTZ VEIN FORMS PROMINENT RIDGE ON VOLCANIC ROCKS, VEIN BARREN. SW OF SHAFT (BY ROAD) THERE ARE LOW OUTCROPS AND FLOAT OF LIMEY SEDIMENTS.. SW OF SHAFT (BY ROAD) THERE ARE LOW OUTCROPS AND FLOAT OF LIMEY SEDIMENTS.
