Silver rich galena mineralization with minor zinc sampled by drilling in . The mineralization is in fractures and breccias in intrusive rocks. There are two steeply dipping fracture zones dominated by calcite. Traces of arsenopyrite and tourmaline mineralization was also found.
Closely related to the Ersmarksberget mine (also known as Blaiken mine).
