Copper mineralisation in the Vesterdalen prospect was discovered in the early 1900s. Several minor exploration campaigns have been carried out due to elevated gold values associated with the copper occurrence, which is hosted by a sequence of impure dolomite and reddish siltstone that overlies greenstones of the Nussir group. The copper occurrence comprises dissemination, aggregates and veinlets, and the copper mineralogy is very complex. Digenite seems to dominate, but bornite, chalcocite, covelline and malachite also occur. Analysed samples yield values in the range of 0.64–9.76 % Cu and 0.2–16.4 g/t Au. In addition, elevated molybdenum contents were found, with 0.9 % Mo as the maximum value. The molybdenum mineral present is powellite. Accessory minerals include brannerite, orthobrannerite and uraninite. |
