N2 - Gold mineralisation was discovered 1991 in Precambrian supracrustal rocks near the settlement Saqqaq on southern Nuussuaq. The supracrustal sequence comprises a lower, ultramafic to mafic volcanic unit and an upper, predominantly clastic unit. A 3-4 m wide, rusty weathering metachert horizon of exhalative origin occurs at the transition between the volcanic and clastic units. This horizon contains disseminated pyrrhotite, pyrite, arsenopyrite and gold grains up to 20 microns in size, and chip samples collected at five localities over a strike length of 1.6 km average 1 ppm Au. The supracrustal unit thus has a potential for sedimentary-exhalative-derived gold deposits and constitutes a new exploration target in the Disko Bugt area.
