Description

A ground electromagnetic survey was performed by Nordic Mining in 2012, and 3D-modelling revealed a 600x600 m conducting anomaly between the depths 60 and 110 m below the surface. The existence of sulphide-bearing zones with elevated Ni, Cu, Au and PGE was confirmed by two drill holes also in 2012. The deposit area shown in the database encompass the central dunitic surface area and does not delineate the EM-anomaly.

Exploration activities by Norsk Hydro A/S in 1971 revealed Ni-Cu mineralizations related to a peridotites between Reinfjord and Tverrfjord. During accompanying fieldwork, it was found that these mineralizations were related to the cooled margin on the edge of an intrusive magmatic complex with a well-defined cumulus structure. The mineralizations became subject of a MSc dissertation at NTH (currently NTNU) that included geological field mapping, sampling of rock, stream sediments and heavy mineral concentrates, as well as mineral liberation and separation (Søyland Hansen 1971). An aeromagnetic survey was done in 1965 by NGU (Roberts 1974). The ultramafic complex essentially consists of layered dunites, peridotites and pyroxenites intruding a garnet gneiss in the SW, and layered gabbro elsewhere. On the contact of the Reinfjord ultramafic and the garnet gneiss in the SW, disseminated sulphide minerals occur as interstitial grains in the ultrabasite. The contact is exposed at one locality up in the Bonjikdalen valley, and also crops out right under a rusted mineralized zone in an outcrop in the valley E of Småvatna. The sulphide minerals observed include pyrrhotite, chalcopyrite, pentlandite, and pyrite. Surface weathering has altered the pentlandite to bravoite, occurring as isolated grains. Pyrite occurs locally with chalcopyrite. The same sulphides also occur interstitially in the pyroxenite, in which the rock forming minerals have a granular texture. The grain size of the mineralization depends much on the grain size of the host and varies from 2cm in a coarse grained rock down to 50mu in a fine grained rock. Even finer grains of 1-20mu of pyrrhotite and chalcopyrite may rarely occur included in the silicates, and locally the sulphides seem to have been remobilized in cracks in the silicates. The mineralized outcrop E of Småvatna is void of layering and lacks a contact with the garnet gneiss; instead, the contact runs just below it, under the rockfall. The mineralization stretches S towards the Bonjikdal valley. In addition to this mineralization there is a small pyroxenite dome in the garnet gneiss 30m SW of Storvatnet, showing disseminated pyrrhotite, chalcopyrite, and pentlandite (sample 01). In May 2012 Nordic Mining conducted a drilling program of two holes to 243 and 169 meters in depth respectively. Drill hole RF-1 intersected two zones of disseminated sulphides. A Ni/Cu rich zone (between 86 and 93 meters) underlain by a more PGE+Au enriched zone (between 107 and 117 meters). The PGE zone was characterized by pegmatitic texture with coarse grained pyroxene, blue quartz and plagioclase . See company web pages for details. www.nordicmining.no

Abstract:

General descriptions of the different metasediments, metavolcanics and igneous rocks within the map area are presented. Three principal map-subdivisions are recognized; (a) supracrustal Precambrian (Karelian) rocks occurring in tectonic Windiws; (b) autochthonous late Precambrian to Lower Cambrian (meta)sediments; and (c) a thick allochthonous nappe-complex od Eocambrian to Cambrian metasediments, gneisses and various igneous rocks. In addition to these lithologies, sediments of unknown age (but possibly Silurian) lying unconformably upon allochthonous gneisses are noted from the south-western corner of the map-sheet. Descriptions are given of the many types of plutonic rocks occurring within the Seiland-Stjernøy petrographic province. These include several varieties of gabbro as well as diorites, peridotites, syenite, nepheline syenite, hornblendite, carbonatite, anorthosite, trondhjemite and adamellite. The major tectonic structural subdivisions of the map-area are outlined and it is shown that the matamorphic lithologies of the allochthon, here referred to as the Kalak nappe-complex, can be readily separated into three main tectonic units, or nappes.

	High-temperature ultramafic complexes in the North Norwegian Caledonides: I - Regional setting and field relationships.

;Norges geologiske undersøkelse;TIDSSKRIFTARTIKKEL;NGU Bulletin; No.405;1-40 pages

Abstract:

Forkortet. Four major (25-100 km²) ultramafic complexes were developed in the Sørøy Nappe during the second phase of Finnmarkian deformation in the North Norwegian Caledonides. They were emplaced into layered mafic intrusions and show broadly similar emplacement histories and petrographic variations suggesting a related petrogenesis. The Nordre Bumannsfjord, Melkvann and Kvafjord group of ultramafic complexes developed in part by emplacement of both replacive and dilational ne-normative ultramafic sheets and dykes which progressively fragmented the layered olivine gabbro envelope. The Reinfjord ultramafic complex contains pronounced, subhorizontal modal layering and evidence of at least 3 major magmatic events. The intrusive sequences and petrographic variations represented in the complexes suggest the succesive emplacement of mantle-derived magmas with a diminishing number of liquidus phases, accompanied by in situ liquid-crystal fractionation, subsidiary hybridization and metasomatism.
