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.

Comment (Deposit): Discovery Year: 1934 (HG); 1982 (AU)

Comment (Deposit): First Production Year: 1986 (AU)

Comment (Geology): ARGILLIZATION POSSIBLY OCCURRED DURING THE EARLY STAGES OF DENSE SILICIFICATION. TWO TYPES OF SILICIFICATION, DENSE AND POWDERY, ARE DISTINGUISHED ON CROSS SECTIONS AND BENCH MAPS AND ARE THE TWO DOMINANT TEXTURAL TYPES OF SILICIFICATION PRESENT IN THE DEPOSIT, ALTHOUGH ALL GRADATIONS EXIST. DENSE SILICIFICATION CONSISTS OF VERY FINE-GRAINED QUARTZ (0.01-0.05 MM) AND/OR OPAL, 5-20% FINE GRAINED DISEMINATED MARCASITE AND/OR PYRITE (TYPICALLY <0.025 MM), AND A TIO2 PHASE (ANATASE OR LEUCOXENE) THAT TOTALLY REPLACE THE ROCK EXCEPT FOR QUARTZ AND ZIRCON PHENOCRYSTS. DENSE SILICIFICATION IS ASSOCIATED WITH AU-AG DEPOSITION. RELICT TEXTURES IN POWDERY SILICIFIED ROCKS SUGGEST THAT MANY OF THESE ROCKS WERE FIRST DENSELY SILICIFIED (+ FINE-GRAINED SULFIDE MINERALS) AND WERE LATER OXIDIZED, PARTIALLY LEACHED, AND RECRYSTALLIZED TO POWDERY SILICA (ACID LEACHING BY ASCENDING FLUIDS?). POWDERY SILICA ALTERATION IS ASSOCIATED WITH HG DEPOSITION. GEOLOGY COMMENTS: SIX MAJOR EPISODES OF

Comment (Deposit): STUDIES TO DATE SUGGEST AT LEAST 3 STAGES OF HYPOGENE AU DEPOSITION FORMED AN ORE ZONE THAT IS ELLIPTICAL, ABOUT 200 BY 450 M IN PLAN AND ELONGATED IN A NW DIRECTION. SOME HOST ROCK IS BRECCIATED WITH QUARTZ-SULFIDE MATRIX. BRECCIA EXHIBITS HYDROTHERMAL REPLACEMENT TEXTURE. BOTTOM OF ORE ZONE IS NOT YET DEFINED, BUT IT DIPS 15 SE, AND THINS OUT ON SE EDGE, TO 15-20 FT THICK. MINERALIZATION IS BOUNDED ON THE WEST SIDE BY A FAULT WHICH WAS ACTIVE BEFORE MINERALIZATION EVENT, ACTING AS A DAM TO MINERALIZING FLUIDS. FAULTS OFFSET ORE ZONE ON NORTH AND EAST SIDES. CURVILINEAR FAULTS ENCIRCLE ORE ZONE AND DROP CENTER DOWN. ORE ZONE IS NEARLY STRATIFORM CONFINED LARGELY TO THE FELSIC VOLCANICS ALTHOUGH THERE IS SOME AU-AG MINERALIZATION IN THE UNDERLYING DACITES. AU-AG MINERALIZATION IS CONFINED TO THE SILICIFIED ROCKS. ORE ZONE IS ABOUT 100 FT THICK. ORE ZONE BOUNDARIES ARE SHARP.

Comment (Development): EXPL.COM: ON THE BASIS OF VISIBLE HYDROTHERMAL ALTERATION AND PRESENCE OF OLD HG WORKINGS IN THE AREA, PROSPECTORS MR. AND MRS. WILLIAM ARNELL BROUGHT THE PARADISE PEAK PROPERTY TO THE ATTENTION OF FMC GEOLOGISTS IN 1982. THE FIRST SAMPLES FROM THE DEPOSIT COLLECTED BY FMC GEOLOGISTS IN EARLY 1983 WERE HIGHLY ANOMALOUS IN AU AND AG. FOLLOWING A DETAILED SURFACE SAMPLING PROGRAM, DRILLING BEGAN IN JUNE, 1983. THE FIRST DRILL HOLE INTERCEPTED OVER 80 FT. OF ALTERED ROCK CONTAINING O.35 OPT AU; 7 0F THE FIRST 18 HOLES ENCOUNTERED ORE. DRILLING ON 60 M CENTERS WAS COMPLETED IN DECEMBER, 1983 AND WAS IMMEDIATELY FOLLOWED BY DRILLING ON 30M CENTERS OVER THE ORE ZONE. 7TH LARGEST GOLD DISCOVERY IN RECENT U.S. HISTORY, ANNOUNCED IN JAN. 1984. MILL CONSTRUCTION BEGAN ON JANUARY 1, 1985, MINING BEGAN IN DECEMBER, 1985, AND THE FIRST DORE WAS POURED IN APRIL, 1986. ; TOTAL$: 100 ; ECON.COM: PLANNED 100,000 OZ AU/YR AND 3.5 MILLION OZ AG/YR PRODUCTION, AS WELL AS 200,000 LB HG PER YEAR, ORE

Comment (Geology): HYDROTHERMAL ACTIVITY ARE RECOGNIZED WITHIN ORE ZONES: EARLY SILICA-SULFIDE ALTERATION, 2) EARLY HYDROTHERMAL BRECCIATION, 3) EARLY OXIDATION AND LEACHING, 4) BLACK MATRIX HYDROTHERMAL ALTERATION, 5) OPAL-JAROSITE MATRIX HYDROTHERMAL BRECCIATION, AND 6) LATE OXIDATION AND LEACHING. SEVERAL OTHER HYDROTHERMAL EVENTS ARE EVIDENT IN SURROUNDING WALLROCKS. MINERALOGY, ALTERATION, TEXTURAL AND STRUCTURAL FEATURES, AND LIMITED FLUID INCLUSION AND STABLE ISOTOPE DATA INDICATE THAT THE PARADISE PEAK DEPOSIT FORMED AT VERY SHALLOW DEPTHS (<200M) AND LOW TEMPERATURES (150-200 DEGREES C) FROM ACIDIC, LOW SALINITY, PERIODICALLY BOILING FLUIDS. ALTHOUGH IT IS CLASSIFIED AS AN ACID-SULFATE TYPE HYDROTHERMAL SYSTEM, TYPES AND DISTRIBUTION OF HYDROTHERMAL ALTERATION, INTENSITY OF HYDROTHERMAL BRECCIATION, AND THE GEOCHEMICAL SUITE OF ELEMENTS IN THE DEPOSIT DIFFER FROM BOTH TYPICAL HOT SPRING GOLD DEPOSITS AND DEEPER LEVEL ACID-SULFATE SYSTEMS.

Comment (Deposit): THIS RECORD CONTAINS INFORMATION FROM MRDS RECORD W700600, WHICH HAS BEEN DELETED.

Comment (Reserve-Resource): STRIPPING RATIO 2:1

Comment (Commodity): INITIALLY, 46 OF 77 TEST HOLES AVERAGED 0.14 OZ/T AU, 4.7 OZ/T AG. AU OCCURS AS NATIVE AU WITH NEGLIGIBLE AG CONTENT. AG IS PRESENT AS CERARGYRITE, EMBOLITE, ACANTHITE, NATIVE AG, AND IODYRITE. CINNABAR IS FOUND IN VUGS IN SILICIFIED ROCK; HG DEPOSITION APPARENTLY POST-DATES THE MAIN DEPOSITION OF AU AND AG. THE AG:AU RATIO RANGES FROM 4:1 IN THE UPPER PORTIONS TO >500:1 IN THE LOWEST PORTIONS OF THE ORE ZONE. THE AG:AU RATIO VARIES WITH AG CONTENT SINCE AU CONTENT COMMONLY STAYS HIGH THROUGHOUT THE ORE ZONE. THE OVERALL AG:AU RATIO IS APPROX. 33:1. THE ANOMALOUS GEOCHEMICAL SUITE ASSOCIATED WITH AU-AG ORE IS BI + SB + HG + BA + PB + TI + AS FEMO SN TL. THIS SUITE APPEARS TO BE A HYBRID OF SOME ELEMENTS COMMON IN HOT SPRINGS SYSTEMS AND OTHER ELEMENTS TYPICAL OF DEEPER, GENERALLY HIGHER TEMPERATURE SYSTEMS. HIGHLY ELEVATED LEVELS OF MO AND SN IN SOME SAMPLES MAY INDICATE A CLOSE GENETIC RELATIONSHIP TO A SHALLOW FELSIC INTRUSION. BASE METALS TEND TO INCREASE WITH DEPTH, BUT CU AND ZN

Comment (Commodity): REMAIN EXTREMELY LOW THROUGHOUT THE ORE ZONE, AND THUS FAR BASE-METAL RICH VEINS HAVE NOT BEEN DISCOVERED BENEATH THE AU-AG ORE ZONE.

Comment (Workings): HISTORIC WORKINGS AT THE NODY PROSPECT CONSISTED OF A 40 FT. SHAFT AND SEVERAL SURFACE TRENCHES. MODERN FACILITY CONSISTS OF AN OPEN PIT, 4000 TPD MILL, AND HEAP LEACH FACILITIES.

Comment (Geology): ALTERATION COMMENTS: PROPYLITIZATION, ALUNITE-JAROSITE ALTERATION, ARGILLIZATION, DENSE SILICIFICATION, POWDERY SILICIFICATION (ACID LEACHING?). OLIGOCENE ANDESITE AND OLIGO-MIOCENE TUFF UNDERLYING THE PRINCIPAL ORE HOST ROCKS ARE WEAKLY TO STRONGLY PROPYLITIZED, WHICH PROBABLY REFLECTS DEUTERIC ALTERATION THAT PREDATES THE MAIN HYDROTHERMAL SYSTEM AT PARADISE PEAK. HYPOGENE ALUNITE-JAROSITE ALTERATION PRIMARILY OCCURS AS A CRUDELY STRATIFORM LAYER 20-40 M THICK BELOW HYDROTHERMAL BRECCIAS THAT CAP THE DEPOSIT AND ABOVE THE MAIN SILICIFIED ORE ZONE. ARGILLIC ALTERATION CONSISTS DOMINANTLY OF SMECTITE, OPAL-CT, QUARTZ AND LEUCOXENE, WITH MINOR MIXED LAYER ILLITE-SMECTITE AND/OR KAOLINITE PRESENT. UNOXIDIZED ARGILLIZED ROCKS ALSO CONTAIN 5-15% DISSEMINATED FINE GRAINED PYRITE AND/OR MARCASITE. ARGILLIZATION IS WELL DEVELOPED IN THE UPPER ANDESITES THAT OVERLIE THE MAIN SILICIFIED ZONE AND IN THE DACITE PORPHYRY BELOW THE MAIN SILICIFIED ZONE. BOTH ALUNITE-JAROSITE ALTERATION AND

Comment (Development): PRODUCTION CAPACITY: 1-3 MILLION TONNES/YR. EXPECTED TO HAVE A 10-YR LIFE. MILL HAS A DESIGN CAPACITY OF 4000 TPD. OVER THE MINE LIFE, THE STRIP RATIO WILL AVERAGE 1.5:1. DORE IS 96 WEIGHT % AG, 3.5 WEIGHT % AU. A TOTAL OF 185 PERSONS WERE EMPLOYED BY FMC AT PARADISE PEAK IN 1986. MINING CEASED: MAIN PIT-APRIL 1993; COUNTY LINE OREBODY-APRIL 1992; KETCHUP FLAT-AUGUST 1993. MILLING CEASED IN MAY 1993. PRODUCTION FROM ORE ON LEACH PADS WILL CEASE IN 1994. DEPOSIT/OREBODIES MINED OUT (READ, ORAL COMM.).
