Work History
Staked as CW cl 1-23 (Y13081) in Jun/66 by Northlake Mines Ltd (Augustus Exploration Ltd, Silver Standard Mines Ltd, Transcontinental Resources Ltd, Copper Ridge Mines Ltd, and North Pacific Mines Ltd) over airborne mag and EM anomalies from a survey flown a few months earlier. Later in the year, Northlake completed prospecting and grid soil sampling over two areas of geophysical response (#12 and #13).
The area around the occurrence (the 2 EM conductors) presently lies within an area withdrawn from staking due to land claims negotiations.
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) that have been intruded by Mississippian granitic intrusions and later Jurassic, Cretaceous and Eocene intrusions. The YTT is a volcanic-plutonic pericratonic arc assemblage that was strongly deformed and metamorphosed by Late Triassic time. 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 Devonian to Mississippian Kudz Ze Kayah felsic metavolcanic unit, and the Wolverine deposit (Minfile Occurrence #105G 072) within the Lower Mississippian Wolverine Succession.
Northlake Mines outlined 2 EM conductors coincidental with Cu, Pb and Zn soil and silt anomalies near the contact between conductive and non-conductive formations. Ground follow-up prospecting and geological mapping failed to located any mineralized float or outcrop.
