Vagar license covers ground belonging to the Nanortalik Gold Province and is situated in the southwestern part of Greenland close to the towns of Qaqortoq and Nanortalik. The basement terrain of South Greenland is Proterozoic in age, formed from the roots of a NE-SW-trending fold belt developed along the southern margin of the Archaean craton. Plate tectonic processes took place from 1850 to 1725 MA.

Based on surface sampling at its Vagar gold property in South Greenland during 2010, NunaMinerals recognised that at several known gold occurrences within the property, gold mineralization was hosted by altered granitic rocks, in addition to quartz veins and veinlets.

The bulk of the regional geological data from the property comes from Nunaoil A/S and Crew Gold Corporation, who did regional scale scree and drainage sediment sampling and reconnaissance rock sample between 1991 and 2005. Several gold occurrences and clusters of gold anomalies were discovered with notable localities including: LGM showing, Amphibolite Ridge, UFO Mountain, Vein Swarm and Tom’s Vein with new discoveries made by NunaMinerals at UJA-109, Qoorormiut North as well as placer gold-tungsten prospects within the Qoorormiut and Niaqornaarsuk rivers and deltas.

Amphibolite Ridge

At the Amphibolite Ridge, Nunaoil A/S located two narrow auriferous quartz veins. Subsequent chip sampling of the “Vein 2” quartz veins and host quartz-diorites and granodiorites at vein 2 perpendicular to the vein at 7.5 meter intervals revealed a high grade gold environment as summarized in the table below. Chip profiles B to F are open to the east ending with gold grades between 1 and 12 g/t at the last samples.

NunaMinerals drill hole DH-12-02 from the 2012 reconnaissance drilling tested the above mentioned vein 2 anomalies. DH-12-02 intersected 79.00 metres @ 0.91 g/t Au, including 54.70 metres @ 1.33 g/t Au, including 23.30 metres @ 2.47 g/t Au. The end of the hole is still mineralized.

Selected diamond drill results, Vagar Gold Project

The gold mineralized intersection is hosted by hydrothermally altered granitic rocks with enclaves of mafic rocks. Litho geochemical studies based on 81 samples, petro-graphical studies based on 29 polished thin sections as well as geochemical results of 594 drill core and 275 surface samples have shown characteristics that are typical for Igneous Related Gold Systems (IRGS). These characteristics include widespread gold mineralization in granitic rocks, elevated bismuth values, sericite, and alkali-feldspar and carbonate alteration. The alteration pattern is complex with narrow zones of strongly altered rocks within packages of less intensely altered rocks.

The presence of different mineralization styles including narrow, gold rich quartz veins and wide, gold mineralized granitic rocks within the same district is a typical characteristic of IRGS.
