Comments
Comment (Commodity): NO AU WAS SAMPLED BUT MINERAL EXAMINER WAS QUITE ENTHUSED OVER THE POSSIBLE MINING OF FELDSPAR (KAIS:, O8, WHICH HE FELT WAS COMPARITIVE TO THE FELDSPAR THAT IS MINED IN THE BLACK HILLS OF SOUTH DAKOTA. THE TEXTURE OF THE CRYSTAL IS POIKILITIC WHICH MAY DETRACT FROM THE VALUE OF THE SPAR.
Comment (Workings): A DISCOVER CUT WAS THE ONLY WORK
Comment (Deposit): A PEGMATITE DIKE CUTS THRU THE AREA.
