Assessment of orogenic gold mineralisation in Greenland

An orogenic gold deposit has been mined at Nalunaq (South Greenland) from 2004 to 2013 when the operation was closed. A total of 10.65 tons (375,670 oz) of gold was produced during that period. In order to assess the potential for undiscovered orogenic gold deposits in Greenland, a workshop in Copenhagen (November 2014) investigated geological, geochemical and geophysical data. The main conclusion was that areas of South Greenland in relative proximity to the closed Nalunaq gold mine and the Archaean terranes of southern West and South- West Greenland have the highest potential for finding new orogenic gold deposits. The highlights from this workshop are presented here.
