Work History

Staked as Vic cl 17-24 (Y53568) in Jul/70 by Conwest Exploration Company Ltd following a reconnaissance geochemical program. Only preliminary prospecting and soil sampling was carried out.

Capsule Geology

The area is located on the east side of Tyrrell Creek approximately 40 km northeast of the northern end of the Talbot Arm of Kluane Lake. The area was mapped in the 1960¿s by Muller (1967) of the Geological Survey of Canada. S. Israel (2004) of the Yukon Geological Survey published a geological compilation of southwest Yukon which covered this area.
The area is underlain by metasedimentary and metavolcanic rocks assigned to the Yukon Tanana Terrane. Information is limited however geological compilations by Israel and others suggests that the metamorphic rocks consist of quartzite, schist, metaconglomerate and meta grit tentatively assigned to the Devonian to Mississippian and (?) older Nasina Assemblage. The metamorphic rocks are intruded by a stock of alaskite assigned to the Early Tertiary Nisling Range Suite. The occurrence occurs near the contact between the metamorphic rocks and the stock.
The claims were staked to cover silt anomalies discovered during a regional geochemical sampling program. No assessment or other exploration results appeared to have been published. Conwest Exploration¿s 1969 and 1970 annual reports state that substantial prospecting and geochemical reconnaissance programs were carried out in the Yukon in 1970. Federal Government exploration summaries for 1970 also note that Conwest Exploration was active in the area. No mineralization of any significance was found.
