Work History

Staked as Our cl (Y29406) in Aug/69 by D. Thrasher. Cominco Ltd staked the Tin cl 1-96 (YB49431) southwest of the occurrence in Jun/94. In Feb/96 the company staked Tin cl 97-347 (YB77185) to the northwest.

Capsule Geology

Geological mapping (Murphy et al. 2001) shows the region is dominantly underlain by a layered sequence of Devonian to Early Mississippian metavolcanic and metasedimentary rocks of the Yukon-Tanana Terrane (YTT). The YTT is a volcanic-plutonic pericratonic arc assemblage that was strongly deformed and metamorphosed by Late Triassic time. Jurassic and Cretaceous intrusions in the region are relatively undeformed. Volcanic-hosted massive sulphide deposits exist at different stratigraphic positions within the YTT including the Fyre Lake deposit (Minfile Occurrence #105G 034) in the Devonian to lower Mississippian(?) Fire Lake mafic metavolcanic unit, the Kudz Ze Kayah deposit (Minfile Occurrence #105G 117) in the Mississippian Kudz Ze Kayah felsic metavolcanic unit, and the Wolverine deposit (Minfile Occurrence #105G 072) within the Lower Mississippian Wolverine Succession.
The Our claims, were reported to cover a sequence consisting of micaeous quartzite and marble. Cominco staked the Tin claims to explore for volcanogenic massive sulphide deposits similar to their Kudz Ze Kayah deposit. The occurrence lies within the Late Devonian North Lakes meta-diorite Dum unit, serpentenized ultramafic rock that is inferred to be an intrusion. The ultramafic body has intruded Devonian Fire Lake metavolcanic rocks.
