The Vakkerlien nickel prospect is a small sulfide mineralized zone centrally located within a metagabbro body.The body, and a second barren metagabbro, are elongated parallel to the regional lineation.Both are compositionally zoned across the bodies from ultramafic to Dresser metagabbro.The composition of the bodies suggests that they may represent a differentiated mafic sheet, the sheet being disrupted into its present form during MENS SOFTGOODS regional deformation.

Mineral chemistry reveals a complex, possibly two phase, metamorphic history.Three sulfide types are distinguished, all containing the same sulfide phases in varying proportions.The sulfide composition suggests that the sulfides have suffered some metamorphic re-equilibration.The mineralized zone is considered to be partially in an original magmatic position with some additional concentration during deformation.
