Work History
Staked as Bev 198-253 cl (Y83692) in Oct/74 following airborne surveys by Hudson Bay Exploration and Development Company Ltd, which conducted ground mag and EM surveys in 1975 and drilled one hole (142.5 m) in 1976. The Bev claims were part of a regional program spanning several map sheets conducted by Hudson Bay in the late 1970's.
Restaked within Mink cl 1-10 (YB70203 ) and cl 11-20 (YB70558)( designated Mink West), by YGC Resources Ltd in Oct/95. YGC staked Mink cl 21-36 (YB70213, designated Mink East) 6 km to the southeast (Minfile Occurrence #105G 076) at the same time. In 1996, the company explored both claim blocks with geological mapping, prospecting and soil sampling. In 1997, YGC established a grid and carried out detailed soil sampling on Mink cl 1-20 and re-logged diamond drill core on Mink cl 21-36.
Capsule Geology
The Finlayson area 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 (Murphy et al., 2001). 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 Mississippian Kudz Ze Kayah felsic metavolcanic unit, and the Wolverine deposit (Minfile Occurrence #105G 072) within the Lower Mississippian Wolverine Succession
The area is covered by extensive glacial drift. The occurrence is underlain by Upper Devonian metasedimentary rocks (Murphy et al., 2001; unit Dq). Volcanism within the sequence was accompanied by the intrusion of Mississippian mafic to felsic metaplutonic suites.
The Bev claims were staked to cover a number of electromagnetic anomalies outlined from an airborne survey conducted earlier in the year. Follow-up ground EM-17 and magnetic surveys were completed in 1975, producing numerous drill targets. The 1976 drill hole (Bev-9) intersected minor sphalerite-galena mineralization above a thick graphitic schist unit.
The Mink claims (Mink West) were staked to cover the location of the 1976 drill hole. Preliminary soil sampling undertaken in 1996 outlined weakly anomalous Cu and Zn values down slope of the drill hole. Detailed follow-up soil sampling completed in 1997 returned no significant anomalous Cu or Zn values up-ice from the drill hole.
