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. 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 (Geology): ALONG SEVERAL HIGH-ANGLE STRUCTURES. SOME BRIGHT RED-ORANGE OXIDES COAT QUARTZITE FAULT BRECCIA (CEMENTED BY FE AND SILICA) FOUND IN THE TRENCH. THE VEIN EXPLORED BY THE CONTACT ADIT AND SHAFTS FOLLOWS A FAULT ZONE WHICH IS UNDULATORY, BUT GENERALLY N-S STRIKING.

Comment (Commodity): ORE MINERALS NOT GIVEN IN THE LITERATURE

Comment (Location): UTM'S ONLY APPROXIMATED-MINE IN SECTION 18 WITH SEVERAL OTHERS ; INFO FROM LAND.ST :(1972)

Comment (Development): NO ACTIVITY AT TIME OF EXAMINATION IN 1983, BUT TRENCHING HAD BEEN DONE IN THE LAST 10 YEARS.

Comment (Deposit): ORE CONSISTS OF FE-STAINED BRECCIATED QUARTZITE CEMENTED WITH COARSE-GRAINED CALCITE. BURT VEIN OCCURS IN QUARTZITE. LENSES OF SOFT RED IRON OXIDE OCCUR.

Comment (Workings): MAP OF WORKINGS AVAILABLE IN CALLAGHAN, 1936, PAGE 22. INCLUDES TUNNELS AND PITS THERE IS ONE ADIT, TWO INACCESSIBLE SHAFTS, AND SEVERAL PITS. ADIT IS PARTLY A CROSSCUT AND PARTLY A DRIFT. IN 1983, THE S-TRENDING "CONTACT ADIT" WAS CAVED AND THE SHAFTS NORTH OF THE ADIT HAD BEEN TRENCHED.THERE IS ONE ADIT, TWO INACCESSIBLE SHAFTS, AND SEVERAL PITS. ADIT IS PARTLY A CROSSCUT AND PARTLY A DRIFT. IN 1983, THE S-TRENDING "CONTACT ADIT" WAS CAVED AND THE SHAFTS NORTH OF THE ADIT HAD BEEN TRENCHED.

Comment (Geology): CONTACT VEIN ALONG FAULT CONTACT BETWEEN THE QUARTZITE & CARBONATES. CARBONATES CONTAIN LENSES OF IRON OXIDE. BURT VEIN STRIKES N 45 W AND 65 SW IN THE QUARTZITE. SAMPLE FROM CONTACT ADIT CONSISTED OF DARK BROWN JASPERY GOSSAN AND SILICIFIED (RECRYSTALLIZED) QUARTZITE FROM THE DUMP. IN THE AREA OF THE SHAFTS THE DOMINANT ROCK TYPE IS A FINE-TO MEDIUM-GRAINED TAN-PURPLE QUARTZITE, DOLOMITE OR LIMESTONE, ALTERED TO A PUNKY MIXTURE OF CLAY AND IRON OXIDES, ALSO EXPOSED ALONG PORTIONS OF THE TRENCHES. THE TRENCHES FOLLOW A HIGHLY IRON-STAINED BRECCIATED ZONE 10-20 FT WIDE STRIKING N45E,DIPPING STEEPLY SE. THIS ZONE CONTAINS BROWN AND RED SILICEOUS (OR JASPERY) FE-RICH PODS AND LENSES. AT S END OF TRENCH, ALTERED LIMESTONE IS EXPOSED WHICH CONTAINS PODS AND VEINS OF GREY CALCITE. LIMESTONE AND QUARTZITE ARE EVIDENTLY JUXTAPOSED BY THRUSTING AT THIS SITE, AS THEY ARE IN OTHER PARTS OF THE DISTRICT, BUT HERE THE UNITS ARE ALSO JUXTAPOSED ALONG SEVERAL HIGH-ANGLE STRUCTURES.

Nevada Gold

Nevada has a total of 368 distinct gold districts. Of the of those, just 36 are major producers with production and/or reserves of over 1,000,000 ounces, 49 have production and/or reserves of over 100,000 ounces, with the rest having less than 100,000 ounces. Read more: Gold Districts of Nevada.
