Work History
Staked as Fox cl (88157) in Apr/63 by Newmont Mining Corporation Ltd. Restaked as Pell cl 1-161 (YB14729) in Aug/88 by Imperial Metals Corp.
Restaked as Bod cl 1-43 (YB49744) by Cominco Ltd in Jun/94 following an extensive airborne survey flown by the company earlier in the year. Cominco carried out reconnaissance mapping and soil sampling later in the summer
In Oct/95 J. Dodge staked Max cl 1-10 (YB70092) 5 km to the southeast.
In Jul/97 Cominco optioned the Bod claims to Pacific Bay Minerals Ltd which carried out a small exploration program on Bod cl 1-8 (YB49744) and cl 17-20 (YB49760). Pacific Bay returned the property to Cominco in Nov/98.
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 Cretaceous and Jurassic intrusions. The YTT is a volcanic-plutonic pericratonic arc assemblage that was strongly deformed and metamorphosed by Late Triassic time.
The occurrence is underlain by Upper Devonian Fire Lake metavolcanic rocks and Eocene basalts (Eb; Murphy et al., 2001). The area was probably originally staked on the basis of airborne geophysical surveys completed by the government in 1963 and follow-up surveys completed by Newmont Mining Corporation Ltd. The area is covered by extensive overburden.
Mortensen and Jilson (1985) reported the presence of Late Devonian to Mississippian interlayered mafic and minor felsic metavolcanic rocks, carbonaceous metasediments and quartzite grits in the general vicinity of the occurrence. In 1993, Cominco discovered the Kudz Ze Kayah property hosted in the Kudz Ze Kayah felsic metavolcanic unit. Further exploration was undertaken in the district to target this stratigraphy to discover new showings. In early 1994 Cominco flew a regional airborne geophysical survey over the majority of the Yukon Tanana Terrane. The Bod claims were staked to cover geophysical targets identified during the survey.
Reconnaissance mapping by Cominco reported float and subcrop of chloritic phyllite and schists which are locally silicified and often iron carbonate altered. The company also reported the presence of intervals of blue quartz-eye wacke, a characteristic of the Kudz Ze Kayah metavolcanic unit. No felsic volcanic rocks were located and soil sampling returned no anomalies of interest.
Geological mapping and rock and soil sampling carried out by Pacific Bay failed to identify any felsic metavolcanic rocks or VMS style mineralization on the claims.
