Geologic structures

Type of structure Local
Structure description Premineral And Postmineral Faults. Evidence For Premineral Age On Faults Nos. 3 , 5 & 12 Is The Pressence Of Pyrite And Pyrite Clasts Filled With Iron Oxide, Along Faults Away From Orebody. All Faulta Except No. 12 Show Postmineral Movement, Horizontal Movements Have Been Suggested To Occur Along Faults No. 2 , 5 & 7 As Well As Vertically.

Ore body information

  • General form LENTICULAR
    Thickness 12.8M
    Length 179.83M
    Width 152.4M

Controls for ore emplacement

  • Formed By Partial Or Complete Replacement Of A Thin Flow Of Porphyritic Rhyolite That Lies Between A Bed Of Pyroclastic Rock Above And A Flow Of Nonporphyritic Rhyolite Below. Ore Solutions Apparently Stopped By Premineral Foliated Bands Of Gouge And Sericite.

Comments on the geologic information

  • GEOL.DESC: ORE BODY REPLACED THE BALAKLALA RHYOLITE, ROCKS ADJOING THE ORE BODY ARE PORPHYRITIC AND NONPORPHYRITIC VARIETES OF THE BALAKLALA RHYOLITE. A BED COMPOSED OF SHALY RHYOLITIC TUFF INTERLAYERED WITH FINE AND COARSE VOLCANIC BRECCIA LIES IMMEDIATLY ABOVE GOSSAN AT THE SURFACE. IT IS ALSO FOUND IN BACK OF THE STOPES IN SW. PART OF THE MINE.
