Helicopter-borne geophysical measurements for mineral exploration at Nussir, Kvalsund, Finnmark
Abstract
The mining company Nussir AS is interested in (re-)evaluating the copper resources in a dolomite layer of the Nussir area in the Kvalsund municipality (Finnmark). To get a better estimate of the extent of this ore deposit and to gain the understanding of the principal geological structure of the region, NGU performed helicopter-borne geophysical measurements (magnetic, frequency-domain EM, spectral gamma ray radiometry) in the Nussir area (size: ~190 km2) in autumn 2007.
