Work History
Staked as Pterd cl 1-10 (Y98056) in Jul/75 by Wernecke Joint Venture (Standard Oil Company of British Columbia Ltd & Aquitaine Company of Canada Ltd). The joint venture added Pnerd cl 1-4 (Y98240) in Aug/75, and Knit cl 1-8 (YA1320), Ptoes cl 1-8 (YA1328) and Skin cl 1-4 (YA1336) in Sep/75. The claims were explored with mapping and ground radiometric surveys later in the year and optioned in 1976 to Eldorado Nuclear Ltd, which added more claims and drilled 5 diamond drill holes (470.6 m).
In 1981 after the Eldorado option expired, the joint venture drilled 3 dimond drill holes (606.9 m). Aquitaine also changed its name to Kidd Creek Mines Ltd in the same year.
In Feb/2005 Twenty-Seven Capital signed an agreement with Cash Minerals Ltd whereby Cash could acquire up to a 75% interest in a large number of claims (including the Bond claims) collectively known as the Yukon Uranium Project.
Cash Minerals diamond-drilled 7 holes for 504 m in 2005.
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 Wernecke Breccia. To the east, Wernecke Supergroup rocks are unconformably overlain by Middle Proterozoic Pinguicula Group rocks. 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.
A 1 500 m long float train of mineralized boulders lies atop a glacier on the Pterd group. Mineralization consists of pitchblende and brannerite in fractures and bleached Fairchild Lake Group argillite. The source appears to lie beneath the glacier or in snow and ice filled gullies on the cirque wall. A small Wernecke Breccia body was mapped in the area.
Several secondary uranium minerals have been identified including green torbernite, yellow autunite and iriginite (a hydrous uranium molybdate) and orange vandendriesscheite (a hydrous uranium plumbate). No significant mineralization was intersected in the drilling in 1976 or 1981.
