A new gold showing was discovered in the Mauken greenstone belt in northern Norway.
The investigated area is a previously unexplored Paleoproterozoic basement window exposed in the allochtonous Caledonides. The main economic mineral potential in the Mauken greenstone belt is associated with orogenic and epithermal gold mineralisation. The deposit consists of three types of auriferous mineralisations: silicification of mafic tuffites with gold-bearing arsenopyrite-pyrite mineralisation. gold-bearing arsenopyrite-pyrite en echelon quartz vein and quartz-stockwork mineralised system. shear-hosted gold-bearing chalcopyrite-pyrite mineralisation in a quartz-ankerite alteration system.
The gold mineralised alteration system was discovered in late autumn 2008, and further developed during the field season 2009. The typical Au content of the samples, range between 1−4 ppm. Presently the maximum Au grade is 5.79 ppm in a rock grab from an arsenopyrite rich silicified amphibolite
The Mauken Greenstone belt is situated between two major fault structures (Fig. 1). The strike of the belt is parallel with the overall NW-SE orientation of the Precambrian terranes in northern Scandinavia. The belt lies in the western extension of gold-bearing shear zones in central Lapland, Finland, which host several large gold deposits, e.g. along the Sirkka deformation zone.
The geology and metallogeny of the greenstone belt is similar to other gold deposits and parallels can be drawn to deposits in Proterozoic rocks in the Svecofennian Province and in the Canadian Shield.
Northern Highlands ApS presently holds a 57.3 km2 exploration licence area, covering most of the Mauken greenstone belt.
