The Åtvidaberg licence area covers 225km². The licence is valid for three years from 30 May 2016.

The licence area is divided in two by the north-northwest south-southeast striking Loftahammer-Linköping deformation zone. In both lithotectonic domains the geology consists of a sequence of metavolcanic rocks that are intruded by several granitic suites. Mineralisation in the Bersbo mine area is characterised by copper-zinc mineralisation, with some evidence of gold and silver, together with pyrrhotite, that is stratabound in interlayered felsic and mafic volcanic rocks. The mines in this area are marked by narrow aeromagnetic anomalies.

In the western Mormors area, there are four former mines where mineralisation occurs in deformation zones in potassium-altered gneisses. The host rocks are altered to quartz-biotite-garnet schists in which chalcopyrite occurs as veins and lenses. The Mormor-type mineralisation is not obviously associated with aeromagnetic anomalies.
