Open Files 1996-18 and 1996-30 presents result from new geochemical surveys conducted in the Gataga Mountain area of the northern Kechika Trough. In the area encompassing the Driftpile Creek and Bear deposits several significant sedimentary exhalative barite-lead-silver-zinc deposits, including Stronsay (Cirque), Akie and Mount Alcock have been discovered further south in the Cambrian to Mississippian rocks exposed along the western margin of the northern Rocky Mountains.
A total of 184 stream sediment, 182 stream water samples were systematically collected. Average sample site density was 1 site per 7 square kilometres over the 875 square kilometre survey area. Spring sediment and waters were collected from 38 additional sites along a narrow belt within the regional survey area. |

Sediment samples have been analyzed for antimony, arsenic, barium, bismuth, bromine, cadmium, cerium, cesium, chromium, cobalt, copper, fluorine gold, hafnium, iron, lanthanum, lead, lutetium, manganese, mercury, molybdenum, nickel, rubidium, samarium, scandium, silver, sodium, tantalum, terbium, thorium, tungsten, uranium, vanadium, ytterbium, and zinc. Water samples were analyzed by inductively coupled plasma mass spectrometry for trace and major elements in addition to pH, sulphate, fluoride and uranium.
Data packages include survey details, data listings, summary statistics, sample location map, bedrock geology map and element distribution maps. Field observations and analytical data are included on diskette.
