The Hosanger district comprise several nickel-copper deposits hosted by the lower parts of a pervasively deformed body of norite, the Hosanger intrusion, belonging to the Lindås Nappe. The first deposit was found in 1875, and mining continued intermittently in the area until 1945 when the operations closed due to the exhaustion of richer ore. Early operations, until 1898, focused on massive mineralisation containing 2–4 % Ni in the southern part of the intrusion. These bodies were socalled "offset" ore, as they occur as veins in the wall rock. The Litland ore was discovered in 1899, but was first mined in 1915, and the Lien ore, further north, was discovered in 1915 but was not mined until 1938. Production figures show Ni grades varying from 0.67 to 1.215 % and Cu from 0.285 to 0.44 % from the group of deposits as a whole. Blackstone Ventures, who currently (2010) hold the claims to the deposit, state that past production totalled 460,000 t grading 1.05 % Ni, 0.35 % Cu and 0.05 % Co.

Abstract:
(forkortet) The Hosanger nickel deposits are situated on the western coast of southern Norway, about 20 km NE of Bergen. Nickel ore has been produced in 4 mines, Nonås, Litland, Lien I, Lien II Smith Meyers mine). The mining district at Hosanger belongs geologically to the Bergen Arch System which has been described by C.F. and N.H.Kolderup (1940). During the geological mapping it was only possible to distinguish two types of rocks: the intrusive gabbroic rocks which on the map has been named gabbro, and the surrounding migmatic gneisses with. The gneisses are of very different composition including granite gneisses with mineral composition: microperthite, quatrtz, oliggoclase, biotite, chlorite, garnet and epidoter and albite- zoisite-gneisses with quartz, albite zoisite and biotite. The intrusive has been the shape of a phacolite chiefly composed of noritic rocks, analysis of which are given in table 1(p.12) together with an analysis of ore diorite from the Flåt nickel mine in Setesdal, Southern Norway. J.H.L. Vogt (1923) has calculated the following mineral composition from the analysis of ore norite from Hosanger: Labradorite 20, hypersthene (with 27 FeSi O3 and some diallag) 60, amphibole 12 and biotite 5.

Vurdering av Hosanger nikkelfelt, Osterøy, Hordaland.

Abstract:
Hosanger nikkelfeltet, bestående av tre hovedforekomster, Nonås, Litland og Lien, var i drift periodevis mellom 1883 og 1945. I alt ble det tatt ut knapt en halv million tonn råmalm med 0,4% Ni, og driften ble stanset p.g.a. mangel på reserver. Diamantboringer og geofysikk foretatt i driftstiden tyder på at det ikke finnes ytterligere massiv malm av noen størrelse. Geologiske og geofysiske arbeider forestått av Elkem i 1970-71 førte ikke til funn av interessant dagnær disseminasjon. Man må konkludere med at feltet ikke har potensiale som berettiger videre undersøkelser.
