Work History
Staked in Sept and Oct/92 as MMM cl 1-12 (YB28964) and Olympic cl 1-86 (YB28634) by a joint venture between Pamicon Developments Ltd, Equity Engineering Ltd and Westmin Resources Ltd, which explored with geological, geochemical and geophysical surveys in Jun/93. The Olympic 99-150 cl (YB22868) were added in Oct/93. The Tow occurrence (Minfile Occurrence #106C 090) and Athens (Minfile Occurrence #106C 093) also occur within this claim block. The Pamicon and Equity transferred 100% interest in both claim groups to Westmin Resources Ltd. in Jan/94.
Between June and Jul/94, Pamicon drilled 4 holes (785 m) on Olympic claims 42, 45 and 60.
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.
Copper mineralization occurs in a breccia body near bodies of anorthosite and diorite. The breccia cuts dolostone at the base of the Gillespie Lake Group. The 1994 drilling tested a geophysical anomaly, a soil geochemical anomaly and the mineralization potential of a lens of Wernecke Breccia. Pamicon assayed for gold, copper, cobalt and silver and measured for magnetic susceptibility and ionizing radiation (count/sec using a scintillometer). None of the holes returned economic values.
