General Information
Deposit Type(s): Iron Oxide Breccias & Veins (Wernecke Breccias)
Location(s): 64.923610 N, -133.6825 W
NTS Mapsheet(s): 106C13

Capsule
Work History
Staked as the Whale cl 1-10 (YB29152) in Oct/92 by a joint venture consisting of Pamicon Developments, Equity Engineering Ltd and Westmin Resources Ltd. The joint venture explored with geological mapping, lithogeochemistry and soil sampling in 1993. In Jul/95 the claims were transferred to Newmont Mines Ltd.
Capsule Geology
The region is underlain by a metamorphosed and altered sequence of Early Proterozoic Wernecke Supergroup clastic and carbonate rocks (Fairchild Lake Group, Quartet Group and Gillespie Lake Group, from oldest to youngest) that are intruded by Early to Middle Proterozoic mafic sills and dykes, and cut by Middle Proterozoic hematitic Wernecke Breccia. According to Thorkelson (2000), Wernecke Breccia development is best modeled as a set of hydrothermal and/or phreatic breccias; brecciation being caused by explosive expanson of volatile-rich fluids. Hunt (2005) attributed Wernecke Breccia formation to periodic over-pressuring of dominantly basinal fluids, which lead to repeated brecciation of host strata and mineral precipitation.
The claims cover a body of Wernecke Breccia and Bonnet Plume River Intrusion diorite intruding argillite of the Fairchild Lake Group.
