Economic information

Geologic structures

Type of structure Regional
Structure description Genesis Mine Is Located Along An Antiformal Axis South Of The Goldstrike Intrusion At The Northern Edge Of The Lynn Window. The Antiform Trends Nw And Plunges 10 Degrees To The Nw. The West Limb Dips 30-40 Degrees West And The East Limb Dips 65-70 Degrees East.
Type of structure Local
Structure description Genesis Mine Occurs On The Tuscarora Spur Horst Block. The Sediments Have Been Folded And Cut By Steeply Dipping Normal And Strike Slip Faults. Faulting Has Three Trends: N20-35w, N30-45e, And E-W. The E-W Trending Faults Appear To Be The Oldest.

Ore body information

  • General form LENSOIDAL
    Strike N10E
    Dip 35W

Controls for ore emplacement

  • The Gen Fault Served As The Main Feeder Zone For Hydrothermal Fluids. The Orebody Is Localized In The Footwall Of Both The N10w Trending Gen Fault And The N15-35e Trending K Fault, With Highest Grade Ore Occurring Near The Intersection Of These Two Faults.

Comments on the geologic information

  • PORPHYRITIC IGNEOUS DIKES HAVE BEEN INTRUDED IN THE VICINITY OF THE GENESIS DEPOSIT, INCLUDING ALONG THE K FAULT. ARGILLIC/SERICITIC ALTERATION OF THE DIKES IS EXTREME. THESE DIKES ARE BELIEVED TO BE RELATED TO THE 156 MA GOLDSTRIKE GRANODIORITIC STOCK, BUT DEGREE OF ALTERATION HINDERS AGE DATING.

Comments on the reserve resource information

  • LINES 1, 2: MEASURED, INDICATED AND INFERRED GEOLOGIC RESOURCES. 1989 FIGURES REPRESENT MEASURED, INDICATED, AND INFERRED ESTIMATES AS OF 12/27/89 USING A CUTOFF OF 0.01 OPT AU FOR BOTH OXIDE AND REFRACTORY ORES.

Comments on development

  • IN 1984, GEOLOGISTS OF CARLIN GOLD MINING COMPANY (PREDECESSOR TO NEWMONT GOLD COMPANY) MAPPED AND SAMPLED AN AREA NORTHEAST OF THE BLUE STAR MINE. BASED ON THE RESULTS FROM ROCK CHIP SAMPLES AND THE SIMILARITIES OF LITHOLOGIES AND STRUCTURES IN THAT AREA TO THOSE SEEN AT BLUE STAR, AN EXPLORATION DRILLING PROGRAM WAS INITIATED. THE EIGHTH HOLE OF THE PROGRAM INTERSECTED 60 FT./0.102 OPT AU. SHALLOW DRILLING IN EARLY 1985 DELINEATED THE NEAR SURFACE PORTION OF THE OREBODY. DEEP DRILLING (DEPTHS OF 400-800 FT.) COMMENCED IN EARLY 1985 AND WAS COMPLETED IN LATE 1986. BY 1986, DRILLING HAD DELINEATED 13.6 MILLION TONS/0.094 OPT AU. OPEN PIT MINING OF THE GENESIS OREBODY BEGAN IN MAY 1986.

General comments

Subject category Comment text
Deposit AU MINERALIZATION OCCURS IN TWO DIFFERENT ZONES AT GENESIS, THE MAIN ZONE AND THE WEST ZONE. THE MAIN ORE ZONE IS PROXIMAL TO THE INTERSECTION OF THE GEN AND K FAULTS WITHIN THE POPOVICH FORMATION. THE WEST ZONE IS STRATIGRAPHICALLY CONTROLLED BY CALCAREOUS SILTSTONE, MUDSTONE, AND ARGILLITE OF THE RODEO CREEK UNIT. DEPOSIT FORM, STRIKE, AND DIP GIVEN ABOVE ARE FOR THE WEST ZONE.
