The Company's field work indicated massive copper sulphide bearing (bornite, chalcopyrite, chalcocite) mineralisation hosted in a sheared vein system that parallels the Kobberminebugt shear. These veins are hosted within a roughly 25m wide diopside-hornblende skarn exhibiting a strong cleavage and hosting lower grade copper mineralisation. This zone is in direct contact with hydrothermally altered Ketilidian granites.

Samples of these vein systems returned up to 4.2% Cu over 2.5m including 11.6% Cu over 50cm. Minor gold and silver grades were also reported.

The Amaroq geology team is now confident in the skarn origin to this mineralisation at Kobberminebugt which opens up the potential for multiple mineralised skarns along the granite contact zone which extends ~40km to the northeast and in a further ~35km contact zone in the north of the licence. This highlights the copper potential of this area of the South Greenland copper belt. Further, from assessing the attitude of the surface mineralisation at Josva, the team believes there is potential that this narrow mineralisation style could open up at depth or along strike, indicating mine scale tonnages.

It is hypothesised these skarns formed late in the orogenic sequence that saw the subduction of material below the Archean craton to the North. These regions along the final suture zone are considered particularly prospective for Iron Oxide, Copper, Gold (IOCG) mineralisation and related hydrothermal and magmatic mineralisation styles.

2023 Exploration Programme

Amaroq intends to follow this exploration with a detailed assessment in 2023 of the skarn geometry and minerology, and plans to generate targets at depth at Josva and along strike of the skarn contact zones and Kobberminebugt shear system through commissioning a detailed airborne geophysical programme utilising a similar system to that successfully employed across the Company's other Greenland assets.

Geological Background

The Kobberminebugt licence covers a coastal area in South-Western Greenland, 25km southwest of Arsuk. The terrain is flat undulating and affords excellent exposure of interbedded metavolcanics, metasedimentary and pyroclastic rocks of the Ilordleq Group exposed along the extent of the Kobberminebugt shear zone, a regionally significant feature. These rocks have been mineralised during the intrusion of a large granite system (the Julianehåb complex) that are late Paleoproterozoic (Ketilidian) in age, and therefore temporally related to the mineralisation observed and reported on within the Company's Sava and North Sava projects over 120km to the East. As with Sava, this area is also spatially related, and possible further mineralised by, Gardar intrusions such as those that host the Kvanefjeld and Tanbreez rare earth development projects; it is however important to note that no elevated uranium has thus far been recorded. As such Amaroq considers that the Kobberminebugt licence forms the western extent of an emerging copper district located along the Gardar - Voisey's Bay Fault Zone that straddles Eastern Canada and South Greenland.
