Work History
Described by the GSC in 1973 and first staked as NOR cl 1-24 (YA10244) in Jun/77 by Getty Mines Ltd, which explored with mapping, geochemical and radiometric surveys in 1977. In 1978 the company drilled 20 Winkie holes (571.2 m) and added Nor cl 25-56 (YA31705 in Aug/78/. In 1979 the company carried out boulder tracing, radiometric and geochemical surveys and trenching and track-etch surveys in 1979-80.
Equity Engineering and Pamicon Development Ltd restaked the occurrence as Diikee cl 1-20 (YB45183) in Jul/93, as part of the Monster Joint Venture. Minor geological mapping, prospecting and soil geochemical sampling was carried out concurrently with the staking.
International KRL completed aeromagnetic, gravity and IP surveys on the property in 2005.
Capsule Geology
The claims cover a fault-bounded northwest-trending elongate outlier of Early Proterozoic Fairchild Lake Group rocks of the Wernecke Supergroup. Fairchild Lake Group limy siltstone and argillite is exposed through unconformably overlying early to middle Paleozoic limestone and siliciclastic units. A 800- by 1800-m heterolithic Wernecke Breccia body intrudes the Fairchild Group rocks. The breccia body, which contains angular fragments of wallrock in a fine matrix, has irregular outer margins, and the wallrock contacts are gradational. 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 breccia pipe hosts two distinct types of mineralization. The earliest phase, consisting of massive magnetite-hematite-jasper-quartz with minor disseminated chalcopyrite in the matrix, occurs in an irregular zone about 30 m across in the northern part of the diatreme.
The second phase of mineralization, which includes coarsely crystalline brannerite with quartz and pink K feldspar, occurs at the east edge of the core of the pipe.
Mineralization at the Nor is similar to styles of mineralization at occurrences in the larger Wernecke Supergroup Inlier of the Wernecke Mountains.
