Ore body information

  • General form IRREGULAR PIPES
    Length 300M
    Width 12M
    Depth to bottom 90M

Comments on the ore body information

  • AROUND IGNEOUS BODIES BUT IN LIMESTONE; ?THE ORE DEPOSITS OCCUR AT OR NEAR THE CONTACT BETWEEN THE GRANODIORITE AND LIMESTONE AND OCCUR CHIEFLY AT OR NEAR THE APEX OF APOPHYSES (GRANODIORITE OUTLIERS) WHICH EXTEND INTO THE LIMESTONE.? (SHENON, 1931). ASSOCIATED WITH THE FRACTURING SURROUNDING THE INTRUSIVES.

Controls for ore emplacement

  • Limestone-Granodiorite Contact, And Associated Fractures

Comments on the geologic information

  • ORE LIES OUTSIDE OF GARNET ZONE. ENTIRELY OXIDIZED ORE OCCURS AT SURFACE BUT BECOMES SULPHIDE IN LOWER WORKINGS.
  • LIMESTONE STRIKES N. 75 DEG E, DIPS 30 DEG NNW. (WINCHELL, 1914)

    GRANODIORITE INTRUSIVES MAY BE SATELLITES OFF OF BOULDER BATHOLITH; BANNACK GRANODIORITE STOCK IS ABOUT 1 MILE LONG AND 1/3 MILE WIDE; ANOTHER SMALLER STOCK LIES 1/3 MILE NORTH OF GRASSHOPPER CREEK; A TABULAR GRANODIORITE DIKE CROPS OUT ON THE BLUE GRASS AND GOLD BUG CLAIMS. (THE TWO STOCKS MAY BE CONNECTED AT DEPTH). (GEACH, 1972)



    ORE IS IN THE LIMESTONE AND NOT IN THE EPIDOTE-GARNET ?TACTITE?
