Thompson, B.N.; Wodzicki, A.; Weissberg, B.G. 1967 Geology and mineralisation of Coppermine Island with appendix on soil geochemistry. Lower Hutt: New Zealand Geological Survey. Report NZGS 25 1 v.
Abstract: This report presents the result of visits to Coppermine Island in Feb 1966 and Feb-Mar 1967, to map the geology and to assess the mineral potential of the island. Coppermine Island is the most easterly island of the Chicken Group, and is 2,000 yards long by an average width of 400 yards. Along the shoreline outcrops are almost continuous, but accesss to these is sometimes impossible. Examinations were made of accessible parts of the coastline, all the major ridges of Coppermine Island, and the eastern shore of Whatupuke Island. All major rock types have been examined petrographically and the grade of copper mineralisation in the two most intensely mineralised areas has been estimated. Preliminary geochemical soil sampling was carried out in 1966, and a more detailed sampling was carried out in 1967. (auth/ARC)
