Comments on the location information

  • 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.

Geologic structures

Type of structure Regional
Structure description The Deposit Lies Within The Mesozoic-Age, N- To Nw-Trending Pinon Range Anticline. Tertiary Age Faults Strike Nw And Nne. One Nw-Striking Fault Set Shows Reverse Displacement And Acted As Conduits For Hydrothermal Fluids.

Ore body information

  • General form TABULAR

Controls for ore emplacement

  • Au Deposition Occurred In Jasperoid Occupying Two Nw-Striking, South-Dipping Reverse Faults And Within Favorable Horizons Of The Webb Formation In The Hanging Walls Adjacent To These Faults.

Comments on the geologic information

  • 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.

Comments on 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
  • 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.
