Comments on the location information

  • THE GREAT EAGLE MINE IS LOCATED IN SW SEC. 23 ON THE SOUTH SIDE OF THE GILA RIVER AND THE MCCAULEY ZONE IS IN NE SEC. 22 ON THE NORTH SIDE OF THE GILA RIVER. ACCURATE LOCATION IS FOR THE SHAFT OF THE GREY EAGLE MINE AS SHOWN ON THE REDROCK TOPOGRAPHIC QUADRANGLE. THE GREAT EAGLE MINE IS INCORRECTLY NAMED AS THE GREY EAGLE MINE ON THE REDROCK QUADRANGLE.

Geologic structures

Type of structure Local
Structure description Deposits Occupy A Northwest Trending Shear Zone About 3500 Ft. Long. The Zone Is Terminated To The Southeast By A Major Bounding Fault And Dies Out To The Northwest, Giving Way To An Aplite Dike. Tertiary Rhyolite And Andesite Dikes Are Numerous In The General Area, But None Are Found In The Mineralized Zone..

Ore body information

  • General form IRREGULAR, PODS, TABULAR
    Strike N 5 TO 51 W
    Dip 85SW TO 59NE
    Thickness 12.19M
    Length 243.84M
    Width 60.96M
    Depth to bottom 60.96M

Controls for ore emplacement

  • Fault-Fracture Structural Control.

Comments on the geologic information

  • THE GREAT EAGLE MINE AND THE MCCAULEY ZONE ARE IN THE PRECAMBRIAN BURROW MTN. GRANITE (AND SOME CRETACEOUS SANDSTONE) MARGINAL TO A MAJOR BOUNDING FAULT WHICH JUXTAPOSED THE GRANITE AND TERTIARY GILA CONGLOMERATE. THE BOUNDING FAULT IS SOMEWHAT ARCUATE, STRIKING N60W AND DIPPING STEEPLY SW ON THE NW SIDE OF THE GILA RIVER. THE GREAT EAGLE FLUORSPAR VEINS OCCUPY A NW TRENDING SHEAR ZONE ABOUT 3500 FT LONG. THE SHEAR ZONE IS CUT OFF ON THE SOUTHEAST BY THE BOUNDING FAULT AND DIES OUT TO THE NORTHWEST, GIVING WAY TO AN APLITE DIKE. THE GILA RIVER BISECTS THE SHEAR ZONE AND THE BEST MINERALIZATION IS TO THE SOUTHEAST. RHYOLITE AND ANDESITE (TERTIARY?) DIKES ARE NUMEROUS IN THE GENERAL AREA, BUT NONE ARE FOUND IN THE FLUORITIZED ZONES.

Comments on the production information

  • A.B. CONNER WORKED THE MINE FROM 1911 TO 1914 AND THEN IT WAS ACQUIRED BY J.H. CAUTHEN OF LAMPASAS, TEXAS. IN 1918 THE GREAT EAGLE MINING CO. BOUGHT THE MINE AND PRODUCED ABOUT 3000 TONS OF METALLURGICAL-GRADE FLUORSPAR FROM 1918 TO 1921. IN 1939 THE FLUORSPAR MILLING CO. REOPENED THE MINE AND IN 1941 SOUTHWESTERN MINING CO. WAS OPERATING THE MINE. IN 1943 THE MINE WAS LEASED FROM THE NEW OWNER, RUTH SPANN, BY D.F. MCCABE WHO SOLD ABOUT 6000 TONS OF ORE FROM THE DUMPS UNTIL 1945. NO PRODUCTION HAS COME FROM THE MCCAULEY ZONE.

Comments on the reserve resource information

  • THE RESERVES FIGURE WAS PUBLISHED BY MCANULTY IN 1978 AND WAS TAKEN FROM REPORTS BY HERBERT DANIEL OF ALLIED CHEMICAL CORP... THE RESERVES ARE DRILL INDICATED.

Workings at the site

  • Type of workings Surface/Underground
    Overall depth 51.82M
    Overall length 495.3M

Comments on the workings information

  • WORKINGS REPORTED IN 1946 CONSISTED OF ABOUT 550 FT OF TRENCHING, A 110 FT SHAFT AND THREE ADITS WITH ABOUT 825 FT OF WORKINGS. ABOUT 250 FT OF DRIFTING WAS DONE IN THE MID 1970'S. THE MINERALIZED ZONE WAS TRENCHED ALONG THE STRIKE FOR 560 FT. AND ADIT 90 FT BELOW THE HIGHEST FLUORSPAR OUTCROP SERVICED ONE OF THE LARGER STOPES. ANOTHER LEVEL 60 FT BELOW THE ADIT WAS SERVICED BY AN INCLINE STARTING NEAR THE SE END OF THE PROPERTY. A 110 FT SHAFT WAS SUNK NEAR THE SE END AND A CROSSCUT WAS DRIVEN TO THE VEIN. ALLIED CHEMICAL DROVE A 240 FT ADIT ON THE NORTH SIDE OF THE GILA RIVER.

Comments on development

  • ALLIED CHEMICAL CORP. CONDUCTED AN EXTENSIVE EXPLORATION PROGRAM IN 1973-74 INCLUDING 6724 FT. OF DIAMOND CORING IN 29 HOLES, 2700 FT. OF PERCUSSION DRILLING IN 44 HOLES, 244 FT. OF DRIFTING ON THE GREAT EAGLE VEIN AND PLANE-TABLE MAPPING OF THE AREA. ALLIED DROPPED THEIR OPTION IN 1975 AND IN 1978 TOM MCCAULEY WAS PLANNING TO MINE THE SOUTHERN PART OF THE PROPERTY FOR METALLURGICAL-GRADE FLUORSPAR.

Deposit THIS RECORD CONTAINS DATA FROM RECORD D009980 BY RONALD G. WORL WHICH HAS BEEN DELETED FROM MRDS. ; INFO.SRC : 1 PUB LIT; 2 UNPUB REPT
Deposit DEPOSITS IN THE GREAT EAGLE SHEAR ZONE OCCUR IN BRECCIAS AND SEVERAL IRREGULAR VEINS RANGING FROM 2 TO 20 FT THICK, EXTENDING TO A DEPTH OF 200 FT, AND CROPPING OUT OVER A HORIZONTAL DISTANCE OF 800 FT. NORTHWEST OF THE MAIN SHEAR ZONE, LOW-GRADE DEPOSITS OCCUR IN THE MCCAULEY ZONE WHICH IS A HIGHLY FRACTURED AREA OF CLOSELY-SPACED NARROW VEINS, VEINLETS AND FILLED FISSURES ABOUT 1500 FT LONG AND 100 TO 300 FT WIDE. THE FLUORITE IN THE VEINS IS MEDIUM TO COARSE CRYSTALLINE AND RANGES FROM COLORLESS TO PALE GREEN TO DEEP GREEN TO PURPLE. MOST MINABLE ORE IS IN THE SOUTHEAST SEGMENT OF THE SHEAR ZONE ON THE SOUTH SIDE OF THE GILA RIVER. THE MCCAULEY ZONE IS MARGINAL TO THE BOUNDING FAULT AND MINERALIZATION IS IN NUMEROUS NARROW VEINS OVER AN AREA 1500 FT LONG AND 100-300 FT WIDE. THE MCCAULEY ZONE MINERALIZATION IS BOTH PRECAMBRIAN GRANITE AND OVERLYING CRETACEOUS SANDSTONE, AND ROUGHLY PARALLELS THE BOUNDING FAULT.

Deposit CLAIMS MINERAL SURVEY NUMBER 1919 AND THREE UNSURVEYED, UNPATENTED CLAIMS.
