Helicopter-borne geophysical measurements for mineral exploration around Ulveryggen, Kvalsund, Finnmark

Abstract

The mining company Wega Mining AS is interested in (re-)evaluating the copper resource around the Ulveryggen in the Kvalsund municipality (Finnmark). In this region Folldal Verk A\/S run a copper mine that was closed in 1979. To get a better estimate of the extent of ore deposits and to gain the understanding of the principal geological structure in the region, NGU performed helicopter-borne geophysical measurements (magnetic, frequency-domain EM, spectral gamma ray radiometry) in autumn 2007 around the Ulveryggen. The measurements were a small part (~40 km\u00B2) of a larger survey carried out south of the Vargsundet.
