The Chimney Creek Mine is a gold and silver mine located in Humboldt county, Nevada at an elevation of 5,200 feet.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

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.

ARGILLIZATION HAS CONVERTED ILLITE TO SERICITE, KAOLINITE, DICKITE, ALUNITE, AND NATROALUNITE. DISSOLUTION AND REPLACEMENT OF CARBONATE BEDS IN ETCHART LIMESTONE CENTERED ON FEEDER FAULTS. EARLY SILICIFICATION (TERMED "BEDDED JASPEROID") IS MOST DIAGNOSTIC ALTERATION PHASE PRESENT AND IS INVARIABLY GOLD-BEARING. LATER SILICIFICATION IS LOCALIZED ALONG FAULTS THAT DISSECT THE CHIMNEY CREEK OREBODY.

MINERALIZING HYDROTHERMAL FLUIDS SPREAD OUT LATERALLY ALONG BEDDING TO FORM THE CONFORMABLE OREBODY, WITH GOLD GRADE DECREASING WITH DISTANCE FROM FEEDER FAULTS. GOLD-BEARING BEDDED JASPEROIDS FORM TABULAR BODIES FROM 30-50 M THICK EXTENDING AT LEAST 600 M OUTWARD FROM THE CENTER OF THE OREBODY.
