The Øksfjord Peninsula sits in The Seiland Igneous Province, 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 Seiland Igneous Province is largely unexplored for high-end metals and is therefore an interesting exploration target. During the past years Nordic Mining has gathered basic data on the geological evolution of the complex and explored areas of interest. This has led to the targeting of on area of particularly interest, The Reinfjord Ultramafic Intrusion in Kvænangen Municipality in Troms County, Norway. Nordic Mining holds the exploration permits (Reinfjord 0125-0127/2011) for nickel, copper, cobalt and platinum group elements in the area. An exploration program was undertaken in the area during 2011 and is continuing in 2012.

The area is regarded as highly prospective for copper (Cu), nickel (Ni), cobalt (Co) and platinum group elements (PGE). Professor in ore geology at university in Trondheim, Rune Larsen, and consulting geologist (Geo Consulting Tmi), Dr. Markku Iljina, specialized in layered intrusions and related nickel and platinum deposits, has been engaged for field exploration, interpretation and for competent advisory for the project.
Interesting grades of Ni, Cu and Co sulphides was mapped by Nordic Mining during the fall 2011. The sulphide mineralization is visible along the margins of the intrusion, and may be termed low grade Contact-Type mineralization. The prospecting model is that a larger and higher grade deposit is located within the depths of the central part of the intrusion.

Nordic Mining contracted the Danish Company SkyTem to carry out airborne geophysical measurements (TDM) in July 2011. An expert review of the data, by Revelation Geoscience, revealed two distinct conductive fields within the central intrusion. The conductors resemble the signature of semi massive and net-textured sulphide mineralizations.
A 3D-modeling of the conductors and the magnetic data show two unexposed gently dipping conductive bodies sitting close to each other and having surface extensions of 75,000 m2 and 180,000 m2. A high magnetic gabbro is shown to surround the intrusion and the conductors. Top edges of the bodies are at depths of 50 meter and 205 meter from the surface. The conductors have a favorable position in terms of reflecting an actual sulphide deposit and fits well with the prospecting model for the area.

Nordic Mining is planning a ground geophysical survey in February/March 2012 to get a more detailed image of the conductors before drilling. Exploration drilling is planned carried out during April/May 2012. The project is still at a non-commercial stage and no proven resource estimate has been made to this date.
