Project overview
- Porsanger is located within the underexplored Karasjok Greenstone Belt, which extends from northern Norway into Finland and the Central Lapland Greenstone Belt. This belt of rocks is highly prospective for magmatic nickel-copper-PGE sulphide deposits.
- The Central Lapland Greenstone Belt is host to the producing Kevitsa nickel-copper mine operated by Boliden, and the Sakatti nickel-copper-PGE deposit discovered by Anglo American in2009. Both Sakatti and Kevitsa deposits are hosted in 2.06 Ga mafic-ultramafic intrusions. Intrusions of a similar age occur at Porsanger and are mineralised.
- Porsanger was drilled in the 1990s by the Norwegian Geological Survey as part of a copper exploration program. The historical drilling intercepted broad, low to moderate grade, palladium dominant PGE mineralisation with copper and rare nickel mineralisation in two small outcropping intrusions called Porsvann and Karenhaugen. No follow up exploration was conducted. Historical intercepts include
- 45 metres at 1.4 g/t 4E and 0.1 % Cu (0.9 g/t Pd, 0.4 g/t Pt, 0.04 g/t Rh and 0.06 g/t Au) from 65 metres (hole PV-01), including
- 15 metres at 2.6 g/t 4E and 0.2 % Cu (1.8 g/t Pd, 0.7 g/t Pt, 0.08 g/t Rh, 0.09 g/t Au) from 90 metres
- 75 metres at 0.9 g/t 4E and 0.1 % Cu (0.6 g/t Pd, 0.3 g/t Pt, 0.03 g/t Rh, 0.03 g/t Au) from 16 metres (PV-04) including
- 1 metre at 6.9 g/t 4E, 0.5 % Cu and 0.1 % NiS (Nickel Sulphide) (5.1 g/t Pd, 1.5 g/t Pt, 0.15 g/t Rh, 0.23 g/t Au) from 34 metres
- Kingsrose intends to explore the known mineralised intrusions for the occurrence of additional disseminated mineralisation as well as explore the potential for higher grade massive sulphide mineralisation which has never been targeted before in the region.
- Exploration by Kingsrose to date has identified a 350m by 400m, shallow conductive body at Karenhaughen, immediately down dip from mineralised outcrop. A new zone of mineralised intrusives was identified in the SW part of the licence area.
- The company is currently applying for drill permits at the Porsvann and Karenhaugen intrusives and will continue with a systematic program at the earlier stage projects to generate additional drill targets.
- 45 metres at 1.4 g/t 4E and 0.1 % Cu (0.9 g/t Pd, 0.4 g/t Pt, 0.04 g/t Rh and 0.06 g/t Au) from 65 metres (hole PV-01), including
Location and Property Description
- Porsanger is located in Finnmark County, northern Norway, next to the coast and near to the town of Lakselv with local airport.
- The project can be reached by main road, with ATV trails and footpaths which cross parts of the licence area. Several powerlines are located within the exploration licence area.
- The area is typified by rocky hills, moorland and forested, shallow but steep sided gullies dissected by a network of streams, ponds and lakes.
Mineral Tenure and Permits
- Porsanger comprises eight contiguous exploration licences A-H, totalling 64.3 km2
- The Exploration Licences are 100% held by Kingsrose Exploration AS, a 100% owned subsidiary of Kingsrose.
- A Special Permit is required for invasive exploration work in Finnmark County, including drilling, according to Article 18 of the Mining Act.
- Kingsrose has completed baseline habitat and cultural surveys at the Porsvann and Karenhaugen prospects in support of drill permit applications.
- The special permit may be refused if the consideration of Sami interests goes against the application being granted. When an application for a special permit is being reviewed, a significant emphasis is placed on the consideration of Sami measures and conditions and potential impacts. For this purpose, statements on applications are requested from the Sami parliament, local reindeer herding district and the Finnmark Estate (FeFo), which is the organisation responsible for the management of majority of land area within Finnmark.
- At Kingsrose, we consider proactive and open dialogue with all our stakeholders and local communities a priority. We have started discussion with the local community and local reindeer herding district well in advance of any investigations taking place in the area.
Geology
- 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.
