Ryberg

Project Overview

MAGMATIC SULPHIDE (Cu-Ni-Co-Pd-Au)

A multi-element project spanning an area of 4,500 square kilometre area on the east coast of Greenland, 430km NW of Iceland.  Ryberg is an under-explored mineral province with a significant amount of magmatism that has intruded the sulphur-rich sediments of the Kangerlussuaq Basin. Geochemical analysis 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 via a high-resolution electromagnetic survey.

Ryberg: Geology

The project area is located within the North Atlantic Igneous Province (NAIP), a Tertiary volcanic centre that covered an area of approximately 1.3 million km2 in continental flood basalts (6.6 million km3 in volume), making it one of the largest volcanic events in history.  Volcanism is associated with the opening of the North Atlantic, and presence of a mantle plume (what is now the Icelandic hotspot).  The project area represents an erosional interface where the flood basalts have been removed, revealing the basement geology beneath. The project area is adjacent to a triple junction (failed rift) and consists of Archaean orthogneiss, Tertiary gabbro/flood basalt, and Cretaceous-Tertiary sediments (rift valley basin).  Approximately 70% of the geology within the sedimentary basin has been intruded by Tertiary sills that are feeders to the overlying plateau basalts.  There are also feeder dykes, and layered mafic intrusions – it is likely that there is also a large ultramafic body present at depth, evidence for this is in the form of ultramafic xenoliths brought to surface by magma conduits. 

Ryberg: Mineralisation

Magmatic sulphides have been seen throughout the licence area, but most activities to date have focussed on the Miki and Togeda Dykes, linear intrusions that combined extend for >50km and have sulphide mineralisation along their margins. The sulphides are globular/disseminated (up to 20cm in diameter) and grab samples taken from the surface grade up to 2.2% copper, 3.3g/t palladium and 0.2g/t gold. Sulphur isotope analysis on the Miki Dyke indicate that the intrusion underwent sulphur saturation after assimilating abundant pyrite from calcareous pyritic black shale within the sedimentary basin.  Regional sediment/stream sampling within the licence area has yielded multiple samples that are anomalous for chromium, nickel, copper and cobalt.

Ryberg: Logistics

Access to site is via aircraft on an existing airstrip located 2km from the licence area, or ship. Internal movements on site are via helicopter.
