Work History
Staked as Too cl 1-10 (YA95285) in Jul/86 by All-North Resources Ltd, which carried out a cursory geological mapping and stream sediment, soil and rock sampling program in 1987.
Capsule Geology
The occurrence is located approximately 80 km east of Whitehorse and 45 km northwest of Johnson¿s Crossing, Yukon. The access road to the Red Mountain deposit (Minfile Occurrence 105C 009), passes 2 km to the west of the occurrence. The area was geologically mapped in the early 1990¿s, at 1:50 000 scale by Gordey and Stevens (1994). Gordey and Makepeace released a geological compilation of the Yukon in 2003. In 2006, M. Colpron of the Yukon Geological Survey released a tectonic assemblage map of the Yukon-Tanana which included this area. Colpron¿s map is a first attempt at producing a compilation map covering Yukon and northern British Columbia portions of the Yukon-Tanana Terrane.
Cursory geological mapping carried out by Aurum Geological Consultants on behalf of All North Resources shows that the occurrence is underlain by metasedimentary and metavolcanic rocks that are cut by a granodiorite dyke of unknown age. Gordey and Stevens assigned these rocks to unit PMgr of the Kootenay Terrane and assigned them a Paleozoic and/or Mesozoic age. Geologically mapping carried out in the late 1990¿s to present by Yukon Geological Survey and others has resulted in the term Kootenay Terrane being replaced by Yukon-Tanana Terrane. Colpron in his geological compilation interprets these rocks as being part of the Upper Devonian to Lower Mississippian Finlayson Assemblage. The Finlayson Assemblage consists of mafic to felsic metavolcanic rocks of arc and back-arc affinities, typically represented by carbonaceous pelite, metachert, minor quartzite, metavolcanic rocks and marble.
The occurrence marks the approximate location of a 29 ppb gold and 36 ppm arsenic silt anomaly discovered by the Geological Survey of Canada (G.S.C.), during a regional stream sediment survey (G.S.C. Open File 1217). Although the company was able to reproduce the stream sediment result (SS-09 = 30 ppb gold and 80 ppm arsenic) they were unable to determine the source of the anomaly. It appears the company never performed follow-up exploration work and the claims were allowed to eventually expire.
