Subject category Comment text
Deposit OXIDE CU MINERALS AND LIMONITE OCCUR ALONG A BULLDOZER CUT FOR 30-40 M. AT ONE LOCALITY, THE MINERALIZATION APPEARS TO BE IN THE FOOTWALL OF A POSSIBLE N 20 E, 60 SE FAULT. THE CHRYSOCOLLA, MALACHITE AND LIMONITE OCCUR AS FRACTURE COATINGS. CALCITE COATS THE OXIDE CU MINERALS
