Subject category Comment text
Deposit WHITE CHALCEDONIC TO CRYSTALLINE QUARTZ OCCURS AS A VEIN FILLING ALONG A N65E, 55 NW FAULT. THE FAULT ZONE IS 1 M WIDE AT THE SURFACE IN CHERT PEBBLE CONGLOMERATE. THE WHITE QUARTZ IS COMMONLY PSEUDOMORPHIC AFTER LAMELLAR CALCITE. LATER, DRUSY QUARTZ OCCURS IN CAVITIES. SPARSE LIMONITE IS PRESENT. THE VEIN MATTER IS VERY BARREN-LOOKING; NO SULFIDE MINERALS WERE SEEN, ALTHOUGH BAILEY (UNPUB.) REPORTS CINNABAR IN A PANNED DUMP SAMPLE. SURFACE AND UNDERGROUND SAMPLING ON A N-TRENDING ALTERED ZONE HAS DISCLOSED ANOMALOUS VALUES OF HG, AS, SB, AND AU.
