The Province is known for its several thousand km2 of layered gabbros that were emplaced at 560-570 Ma. The magmatic stratigraphy comprises ultra-mafic successions overlain by gabbros hence, shares many characteristics with classical PGE-Cu-Ni deposits including the famous Bushveld Complex (BIC).
The figure shows the bedrock geology and sample locations at Øksfjord Peninsula and Stjernøya. Brown is gabbro and violet is ultra mafic rocks. The green dots refer to sample locations and the red rings potential deposits registered in NGUs ore database. Nordic Mining’s pre-claims are located both on Stjernøya and Øksfjord Peninsula.
The “Svovelberget” loaction in Lokkarfjord, belonging to the Seiland layered gabbros, was inspected by geologists from NGU in 2007. Sampling and analysis showed promising values of Cu, Ni, Pt and Pd in semi-massive sulphides. The host rock is hornblendite and covers the north-eastern part of the Øksfjord peninsula. This implies that ore-forming processes did in deed occur during the formation of the layered gabbros.
Sample analysis:
0. 8 wt% Ni
0.72 wt% Cu
0.05 wt% Co
0.8 ppm PGE
The Seiland Igneous Province is largely unexplored for high-end metals and is therefore an interesting exploration target. Nordic Mining is at this stage gathering basic data on the geological evolution of the complex so that interesting areas may be narrowed down for further geological investigation.
