Introduction

The Qussuk gold-copper project operated by the Greenlandic prospecting  company NunaMinerals is located near the Qussuk bay in West Greenland 60 km North-East of the Greenlandic capital, Nuuk.

Combined geochemical and geophysical exploration located at least five exploration targets within a 20-km belt of altered volcanic rock. Several of the geophysical anomalies match known gold- and copper bearing zones.
Surface samples contain up to 35.8 g/t gold and 1.3% copper. Visible gold was first found in this area in 2007.

SkyTEM Survey

In 2007, a combined TDEM and magnetic SkyTEM survey was performed at the Qussuk project covering 48 km2 at a line spacing of 100 meters. The survey was flown with a peak moment of 130 kAm2 (high moment only) and with two receivers recording the response from both the z-and the x-component. Flight height was 20-60 meters and flight speed was relatively low, 30-50 km/h, due to the rapidly changing topography.
