Greenland (100%* Volcanic)

The licence area consists of two granted mineral exploration licences, which combined covers a total area of 3,889km². The location is an under-explored mineral province situated in east Greenland with a significant amount of magmatism that has intruded the sulphur-rich sediments of the Kangerlussuaq Basin. Geochemical anaylsis has identified samples that are rich in copper, palladium, gold and also nickel, cobalt and platinum. Drill-ready targets for massive sulphide accumulations have already been identified, and additional ground that is deemed equally prospective is under application.

Size and grade

Within the licence area is the Miki Prospect (located within the Ryberg licence area), an intrusion that extends for >50km and has sulphide mineralisation along its margins.  The sulphides are globular/disseminated and grab samples taken from surface grade up to 2.2% copper, 3.3g/t palladium and 0.2g/t gold.  In isolated locations, nickel sulphides have been brought to surface and grab samples of these grade up to 0.8% nickel and 0.1% cobalt.

In another locality, a recently discovered Archean greenstone belt has had a total of three surface samples recovered grading up to 2.7g/t gold. The mineralisation can be classified as orogenic style, quartz vein-hosted gold.

Regional sediment/stream sampling within the licence area has yielded multiple samples that are anomalous for chromium, nickel, copper and cobalt.

 


geology

Mineralisation is associated with mafic/ultramafic intrusions emplaced nearby to a failed rift in the Tertiary Period, during the opening of the North Atlantic and when the Icelandic Mantle Plume was located on the East coast of Greenland.  The surrounding geology consists of Archean gneiss, Tertiary gabbro/flood basalt, and Cretaceous-Tertiary sediments. 

Most activities to date have focused on the Miki Prospect, a linear intrusion that extends for >50km. Sulphur isotope analysis suggests that the intrusion underwent sulphur saturation after assimilating abundant pyrite from pyritic black shale within the sedimentary country rock - a key requirement for mineralisation is such a setting.

It is likely that a large ultramafic body is present beneath the Miki Prospect.  Evidence for this is in the form of near surface xenoliths that contain nickel-bearing sulphides.

VTEM Miki gabbro sulphide massive magmatic conductors

work to date

Recent activities have followed up on earlier sampling/mapping and a heli-borne Vertical Time domain Electro-Magnetic (VTEM) survey was flown over the Miki Prospect in 2017.  The survey was used to find conductors (sulphide) at depth and was successful in identifying three targets worthy of follow up drilling, that may represent accumulations of sulphide (the targets are between 60-240m beneath surface).  

Results from the 2017 VTEM survey, coupled with regional mapping and sampling gave impetus for the Company to apply for a large licence adjoining the Miki Prospect to the east. This enlarged area is referred to as Ryberg and contains the known extent of the Kangerlussuaq sedimentary basin that provides the sulphur that is essential for concentrating metals. The basin has been intruded by a plethora of mafic/ultramafic intrusives with known high concentrations of precious and base metals, of which the Miki Prospect is one.

Historically, mineralisation at the project was first identified by Platinova Resources Ltd in 1986.  Over 300 grab samples were taken, and a failed ground EM survey was attempted.  Platina Resources Ltd took further grab samples and geochemical analysis in the period 2008-2011.  


logistics

Ryberg is located in an area suitable for mining on the southeast coast of Greenland, the closest point to Iceland (400km).  This gives an advantage as all staging is conducted out of Iceland, either by sea or air.  Vessels can moor in a protected deepwater fjord (8km south), and aircraft can fly to an airstrip located 1km from the licence area.  

The licence area and proposed drill sites can be reached by foot from the airstrip, and efforts are being made to reduce helicopter reliance when drilling occurs.  This is anticipated to be achieved using ATVs.
