Rich Cu–Ag vein mineralization associated with an amphibolite dyke. Located at the eastern shore of the Tinnsjå Lake, about 1.5 km east of Hovin Church.

The Tinnsjå copper-silver prospect was earlier refered to as the Hovin (or Vasstveit) deposit, which was mined intermittently at the end of the 18th Century and from 1903-04, 1908-10 and 1912-1922, both underground and as an open pit (NGU, 2006).

The prospect is under evaluation by the current (2008) claim-holders (Thorium Norway AS). Copper-silver ore occurs as a ca. 20 m wide vein, with abundant coarse calcite, associated with a ca. 2 km-long amphibolite dyke that lies concordant within a fine-grained Neoproterozoic quartzite.
