General comments

Subject category Comment text
Deposit MINERALIZATION IS DISSEMINATED CHALCOPYRITE AND PYRITE IN MASSIVE, HARD HEMATITE AND SOFT SPECULARITE. THE FOOTWALL ON A SLIP FACE AND GRADE GRADUALLY DECREASING INTO BARREN ROCK TOWARDS THE HANGING WALL; LENSES OF COPPER-OXIDE ORE OCCUR ALONG FOOTWALL, WITH NEGLIGIBLE HEMATITE, AND PASSES INTO CHALCOPYRITE WITH DEPTH; SPECULARITE/HEMATITE INCREASES FROM FOOTWALL UNTIL ONLY TRACES OF SPECULARITE ARE CONTAINED IN THE ROCK.
