High-resolution images from the 2006 Wuskwatim Lake aeromagnetic survey were used in conjunction with new mapping and isotopic data to reinterpret the geology of the Kisseynew Domain (KD) west of the Thompson Nickel Belt (TNB). The results suggest that a 60 km wide zone, previously considered to consist entirely of Burntwood Group migmatite and younger granite, is structurally interleaved with heterogeneous orthogneiss and paragneiss resembling Superior Province basement and the lower part of its cover sequence (Ospwagan Group). These units are exposed in structural culminations suggesting a widespread distribution under a structural cover of the Burntwood Group in the northeastern KD. Iron formations that form aeromagnetic markers may correspond to similar units within the Pipe Formation, making parts of the region prospective for Thompsontype nickel mineralization.
