General comments

Subject category Comment text
Deposit MINERALIZED ZONE STRIKES NEARLY E-W, DIPPING 70 N AT WEST END TO ABOUT VERTICAL AT EAST END. MINERALIZATION OCCURS IN FAULT BRECCIA, WHICH PANS GOLD FREELY, CONCENTRATED IN NARROW CLAY SEAMS THROUGHOUT THE FAULT BRECCIA MATERIAL. HIGH-GRADE ORE DISCOVERY REPORTED IN 1933: RUNNING 7.28 02/+ AU AND 9.27 02/+ AG FROM A GRAB SAMPLE OF SELECTED ORE. ORE WAS REPORTED TO HAVE GIVEN OUT IN 1947. SOME ORE OCCURRED AT INTERSECTION OF THE MAIN ZONE WITH A LITTLE N-S FISSURE WITH A LOW DIP TO THE WEST. ORE WAS ON FOOTWALL OF THE MINOR FISSURE.
