ARCTIC RIFT COPPER Part of world’s newest metallogenic province: Kiffaanngissuseq Technical Assessment Report Greenfields Exploration Ltd November 2020 This report presents a holistic view of north eastern Greenland’s geology. The empirical evidence of mineralisation and geological record are tied in with mineral system components from global through to prospect scales. The source rocks, geodynamic triggers, pathways, and deposition sites are all identified within a preserved terrane. This work defines the Kiffaanngissuseq metallogenic province, a previously undescribed mineral system. For the first time, we identify a c. 1,250 Ma orogenic event in the basement as the geodynamic trigger related to the basalt- hosted native copper within the Arctic Rift Copper project. A c. 385 Ma fluid migration is identified as the trigger for a second copper-sulphide mineralising event expressed within the project, that also emplaced a distal zinc deposit within Kiffaanngissuseq. This multi-episodal mineral system is supported by a regional geochemical and hydrodynamic framework that is not articulated elsewhere. The large scale of the mineral system, widespread copper anomalism, combined with dual mineralising events are analogous to Earth’s great copper systems. The Company considers that Kiffaanngissuseq has the potential to be a world-class mineral province. A coincident magnetic-gravity-conductivty and high-grade geochemical copper anomaly occurs within the project. The anomalism is located at an oxidation boundary and is proposed to be the expression of a hydrothermal outlet. This site of focussed fluid flow forms the basis of a high-priority, near- term target, known as the ‘Minik Singularity’.
