The Porsanger Project comprises 50 square kilometres of exploration licences in the Karasjok Greenstone Belt, and PGE-copper mineralisation is similar in age to Anglo American’s Sakatti nickel-copper-PGE deposit.
Historical drilling of outcropping magmatic sulphide PGE-copper mineralisation returned intersections of up to
- 43.2 metres at 1.2 g/t PdEq (0.9 g/t Pd, 0.4 g/t Pt, 0.1 % Cu) from 67 metres (PV-01) and
- 53.0 metres at 1.0 g/t PdEq (0.8 g/t Pd, 0.3 g/t Pt, 0.1 % Cu) from 2.85 metres (PV-02)
Additionally, narrow stratigraphically controlled high-grade copper mineralisation over 10 kilometres of strike length has been identified in historical rock sampling.
The primary target at Porsanger is massive sulphide PGE-Ni-Cu deposits located at the basal contacts of the Porsvann and Karenhaugen magmatic conduit intrusions. Subject to local approvals, Kingsrose intends to conduct a ground-based electromagnetic geophysical survey to locate conductive bodies, which will require drill testing to assess whether the conductors are related to massive sulphide polymetallic PGE-Ni-Cu mineralisation.
The Porsanger Project is located immediately south of Lakselv town, Finnmark province, northern Norway, and comprises five contiguous 10 square kilometre exploration licences totalling 50 square kilometres. The exploration licences are 100% held by E-46. Initial expiry is in December 2025 with provision for extension.
Porsanger is within the Early Proterozoic Karasjok Greenstone Belt, a north-south trending unit approximately 150 kilometres long and an extension of the Lapland Greenstone Belt. The belts host numerous significant Ni-Cu-PGE, sedimentary copper, and gold deposits in the region, including the recently discovered Sakatti Ni-Cu-PGE project (Anglo American plc) and Ikkari gold project (Rupert Resources Limited).
Two magmatic feeder conduit-style mafic-ultramafic intrusions are present within the project area. The Porsvann and Karenhaugen intrusions are located within the west and east of the area. Both intrusions contain disseminated sulphide (pyrrhotite, chalcopyrite, pentlandite) with associated Pd, Pt, and Cu mineralisation. Surface outcrops are locally stained by malachite. Previous field mapping indicates that the mineralisation is concentrated towards the base of the intrusions and locally within the footwall. The best drill intersection is 43 metres at 1.2 g/t PdEq, including 15.2 metres at 2.1 g/t PdEq. Copper grades range between 0.01 – 0.5 %, this indicates that sulphur saturation was achieved and that the sulphide liquid interacted with a large enough magma volume to enable upgrade of the PGE content.
Copper-dominant mineralisation also occurs more extensively across the property in the form of en echelon and tensional quartz vein arrays hosted by amphibolite and mica schist. Individual vein zones are localised into <30 metre by <2 metre lenticular bodies. These frequently occur along a ten-kilometre-long zone of intermittent mineralisation. The vein mineralogy is quartz with massive to semi massive intergrowths of chalcopyrite and bornite. Individual veins are typically <30cm thick.
