During the South-East Greenland Mineral Endowment Task (SEGMENT) expedition in 2012, the possible mineral potential of the Skjoldungen region was investigated. The region is part of the Archaean North Atlantic Craton, and includes the Skjoldungen Alkaline Province (Nielsen & Rosing 1990; Blichert-Toft et al. 1995; Kolb et al. 2013). A quartz-wolframite-molybdenite vein with phyllic alteration was identified during the reconnaissance work in the northwestern part of the peninsula of Thrudvang, close to the Kangertikajik fjord (GGU 446946; Figs 1, 2). The c. 30 cm wide, subvertical vein is hosted in mafic granulite. However, the deformed nature of the vein and steep terrain did not allow us to establish its extent or general trend.
