Trout Creek Deposit

The Trout Creek Deposit is a silver and gold mine located in Elko county, Nevada at an elevation of 7,201 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.

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): NO EXPLORATION IS KNOWN TO HAVE TAKEN PLACE IN THE AREA PRIOR TO 1979. THE PROPERTY WAS STAKED BY L. L. TREASE AND H. D. CHRISTIANSON IN 1979 ON THE BASIS OF MINERALIZED JASPEROID OUTCROPS. IN 1981, AMOCO MINERALS DRILLED 31 VERTICAL REVERSE CIRCULATION HOLES ON 200-400 FT. CENTERS. THE BEST INTERCEPT WAS 80 FT. GRADING 0.032 OPT AU. A LACK OF CONTINUITY OF MINERALIZATION OVER THE WIDE SPACED DRILLING CAUSED AMOCO TO DROP THE LEASE. IN 1983, FREEPORT MINERALS CO. LEASED THE PROPERTY AND DRILLED 8 HOLES. THE BEST INTERCEPT WAS 40 FT. GRADING 0.083 OPT AU, ALTHOUGH THE DRILLING WAS OTHERWISE DISCOURAGING AND FREEPORT DROPPED THE LEASE. TECK ACQUIRED THE PROPERTY IN 1986 AND CONDUCTED INTENSIVE EXPLORATION FOR ONE YEAR. TECK THEN OPTIONED ITS INTEREST TO LORD RIVER GOLD MINES, LTD., WHO CONTINUES TO FUND EXPLORATION WITH TECK AS OPERATOR. TECK/LORD RIVER HAD DRILLED 32 HOLES IN THE AREA BY 1989. IN 1989, THE PROPERTY WAS STILL IN THE ADVANCED EXPLORATION STAGE. A SOIL GEOCHEMICAL SURVEY

Comment (Development): SHOWS THAT AS DISPLAYS THE MOST WIDESPREAD AERIAL ANOMALIES, WITH AU OCCURRING AS ISOLATED POINT CONCENTRATIONS. HG VALUES UP TO 8100 PPB FORM THIN LINEAR ANOMALIES THAT ARE THOUGHT TO BE LEAKAGE ALONG STRUCTURES FROM MINERALIZATION AT DEPTH.

Comment (Geology): ALTERATION COMMENTS SILICIFICATION, HEMATIZATION. JASPEROID IS DEVELOPED ALONG THE CONTROLLING FAULTS AND ALONG THE WEBB FORMATION/DEVILS GATE LIMESTONE CONTACT. JASPEROID WITHIN THE FAULT HOSTS SMALL VEINLETS OF CALCITE, QUARTZ, AND BARITE AND SHOWS MULTIPLE PERIODS OF BRECCIATION AND SILICIFICATION. AU AND ASSOCIATED ELEMENTS ARE CLOSELY CORRELATED WITH THE DEGREE OF SILICIFICATION. HEMATITE OCCURS WITH JASPEROID AND IN THE DEVILS GATE LIMESTONE IMMEDIATELY BELOW THE CONTACT WITH THE WEBB FORMATION. GEOLOGY COMMENTS THREE AREAS OF MINERALIZATION HAVE BEEN IDENTIFIED: THE SOUTHERN, CENTRAL, AND NORTHERN ZONES. ONLY THE CENTRAL AND SOUTHERN ZONES ARE KNOWN TO CONTAIN SIGNIFICANT THICKNESSES OF ORE-GRADE AU MINERALIZATION. NARROW FELSIC DIKES OF UNKNOWN AGE OUTCROP WEST AND SOUTH OF THE DEPOSIT BUT ARE NOT KNOWN WITHIN IT.

Comment (Location): LOCATED ON THE WEST FLANK OF THE PINON RANGE. THE TROUT CREEK DEPOSIT IS THE NORTHERN PORTION OF A SINGLE HYDROTHERMAL SYSTEM, THE SOUTHERN PORTION OF WHICH IS THE SOUTH BULLION DEPOSIT (RECORD #RE00045). THE PROPERTY BOUNDARY BETWEEN TROUT CREEK AND SOUTH BULLION DEPOSITS IS THE SECTION LINE BETWEEN SECTIONS 22 AND 27, T30N, R53E.

Comment (Commodity): THE AU:AG RATIO IS ABOUT 1: 8.

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.
