Deposit VEIN IS BLACK QUARTZ STRINGERS WITH LOCAL BLOBS OF LIMONITE AND DISSEMINATED CU SILICATES. ALSO CU SILICATES ON FRACTURES. LOCALLY IS SOME WHITE CALCITE IN THE VEIN MATERIAL; ALSO A 30CM POD OF MASSIVE LIMONITE. 4M TO W. IS SIMILAR PARALLEL VEIN. MOST ROCK LOOKS PROPYLITIZED BUT LOCALLY BLEACHED ANDCRUMBLY, SO MAY BE ARGILLIZED AS WELL. ; INFO.SRC : 3 FIELD OBSERV
