Lainejaur Nickel Project

Lainejaur Nickel Project

The Lainejaur Nickel Project is located at the north-west end of the renowned Skellefteå mineral belt of Sweden, approximately 15 km from the regional centre of Malå.The deposit was discovered in 1941 and was bought into production to supply nickel for Sweden during the Second World War. When it closed, the mine had produced 101,000 t @ 2.21% Ni, 0.1% Co and 0.93% Cu, mined to a depth of approximately 100 m below surface.

In 2018, the Company reported an updated Mineral Resource Estimate of 460,000 t @ 2.2% Ni, 0.15% Co and 0.7% Cu.

Lainejaur mineralisation is hosted at the base of the lopolithic gabbro-diorite intrusion overlain by mafic intrusive with minor intercalated metasedimentary units and underlain by meta-basalts. The host unit is interpreted to continue for approximately 1.5 km down dip.

The mineralised horizon forms a distinct tabular shoot plunging at 38° to the north with a defined extent of 800 m. Sulphide mineralisation is defined by a basal layer of massive pyrrhotite, pentlandite and chalcopyrite, typically 1 – 3 m thick, which are overlain by a variably mineralised zone of disseminated sulphides up to 11 m thick.

Sulphides consist of pyrrhotite, pentlandite, gersdorffite and chalcopyrite. Minor arsenical sulphides were also observed. A third, less common, style of mineralisation is represented by nickel-copper-arsenic veins.
