THE CLAIMS ARE PREDOMINANTLY UNDERLAIN BY FELSIC TO INTERMEDIATE VOLCANIC AND VOLCANICLASTIC ROCKS OF THE OOTSA LAKE GROUP (LATE CRETACEOUS TO EARLY TERTIARY). SUBJACENT ROCKS ARE (UPPER TRIASSIC) TAKLA GROUP FLOWS, TUFF AND BRECCIA WITH INTER- BEDDED ARGILLITE AND MINOR LIMESTONE. OVERLYING THE OOTSA LAKE GROUP ARE (MIOCENE) ENDAKO GROUP ANDESITE AND BASALT FLOW ROCKS. NEITHER ROCKS NOR SOIL SAMPLES INDICATE A SIGNIFICANT SOURCE OF GOLD OR ASSOCIATED METALS. INTERMITTANT ZONES OF HYDRO- THERMAL ALTERATION (ARGILLIC; QUARTZ-CHALCEDONY VEINS) ARE SLIGHTLY ENRICHED IN GOLD, ARSENIC AND MERCURY. AN EXCEPTION OCCURS ON THE WESTERN BOUNDARY OF MAR 11, WHERE MERCURY REACHES UP TO 4600 PPB.
