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.
