In February 2009, the company, Scandinavian Highlands Holding A/S, published the results of geophysical investigations by its subsidiary, Harz Minerals GmbH, according to which hitherto unknown mineral deposits of the size of those at the Rammelsberg may be present, two kilometres west of the Rammelsberg ore deposits. In autumn 2009 several exploratory bores were sunk in the area of the Hessenkopf and Gosetal to a depth of 500-600 metres. At the end of January 2010, after a news blackout of several months, the company announced that they would soon be drilling to a depth of 800 metres, where they suspected there would be rich mineral deposits.
