Deposit MAIN ORE BODY AT INTERSECTION OF TWO VEINS. VEINS RANGE IN WIDTH FROM 10 CM TO 2 M, WITH AVE. OF ABOUT 40 CM. MAIN VEIN 60 M LONG, WITH N 20-75 E STRIKE AND 20-60 SE DIP. INTERSECTS VEIN STRIKING N 15-25 W AND DIPPING 25-35 E. MOST ORE FOUND WITHIN 5 M OF INTERSECTION. SOME ORE TAKEN FROM THREE OTHER VEINS IN THE MINE, NONE EXPLORED FOR MORE THAN 40 M ALONG STRIKE. ORE CONSISTS OF LOW-GRADE ANTIMONY OXIDE IN QUARTZ. MUCH OF THE ORE HAS BEEN THOUROUGHLY BRECCIATED AND MYLONITIZED BY POSTMINERAL AND POSTOXIDATION FAULTING PARALLEL TO THE VEINS. SOME ORE CONTAINS ABUNDANT SILVER, WHICH OCCURS AS A BROMYRITE COATING ON FRACTURES IN THE ANTIMONY OXIDE ORE.
