Work History
Originally staked as Don cl in 1954 by K.G. Sanders and R. Zielinski for Pelly River EL (Pioneer Gold ML; American Standard ML, New York-Alaska Gold Dredging Corp and Northwest Ventures L). Restaked in Jan/66 as Gee cl (90172) by Northlake ML (Augustus ML, Silver Standard ML, Transcontinental Res, Copper Ridge ML, North Pacific ML). Northlake flew an airborne mag and EM survey and conducted grid soil sampling and a Ronka survey later in the year on an airborne anomaly labelled Area 5.
Restaked as L & A cl (Y74671) in March/74 by A. Black.
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 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.
The occurrence (Area 5) is underlain by metavolcanic rocks of the Fire Lake metavolcanic unit according to regional mapping (Murphy et al., 2001). Grass Lakes Succession quartzofeldzpathic pebble metaconglomerate lies to the north. Sanders reports that galena occurs in small quartz stringers cutting schist and was panned from the creek flowing into Grass Lake. Soil sampling by Northlake outlined an 'S' shaped anomaly 1524 m long with lead values above 80 ppm, within which two areas exceeded 200 ppm - one on each limit of the 'S'. The anomaly occurs near an anticlinal crest. No conductor was found by the geophysical surveys.
