Land Status

Land ownership: Private
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. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments

Comment (Location): UTM TO SAMPLE SITE 3908. UTM FOR SAMPLE SITE 3929 25 N 4370000 E 0405260 ; INFO FROM LAND.ST :(1972)

Comment (Development): MS #3064. SIZE OF WORKINGS WOULD INDICATE AT LEAST SOME SMALL PAST PRODUCTION. NO ACTIVITY IN 1986, BUT SURROUNDING AREA HAS BEEN RECENTLY STAKED BY ERICKSON (1979-1980)

Comment (Deposit): WORKINGS FOLLOW THE GENERALLY E-W STRIKING VEIN SYSTEM. THERE IS A 200-300 FT BLOCKY OUTCROP OF SILICIFIED RHYOLITE NEAR THE PORTAL OF THE ADIT. WORKINGS FOLLOW A 5-6 FT THICK SILICIFIED BRECCIA FORMED ALONG A FAULT ZONE WHICH INCLUDES A 6-INCH THICK LENS OF LIMONITE-STAINED BRECCIATED QUARTZ VEIN. THE WALLROCK IS COMPOSED OF BLEACHED, KAOLINIZED, SILICIFIED RHYOLITE TUFF. ABOUT 140 FT INTO THE ADIT, A STOPE OPENS TO THE SURFACE, AND A 40 DEGREES DECLINE EXTENDS DOWN, THEN STEEPENS BELOW 40 FT. THE OPEN STOPE IS CONNECTED TO AN ADJACENT SHAFT TO THE EAST, ABOVE THE LEVEL OF THE ADIT.

Comment (Workings): SHAFTS, ADITS, STOPE
