Itilliarsuk is an exploration-stage, banded iron formation-hosted gold project on the southern coast of Nuussuaq. Its approximately 70 km² exclusive exploration licence covers an Archean metasedimentary sequence containing iron formation, quartz-sericite schist, sulphidic mica schist and amphibolite.
Gold occurs in quartz-sericite shear zones, sulphide-rich horizons and BIF layers containing magnetite, pyrite and pyrrhotite. Reported results include 9 g/t Au over 1.7 metres from channel sampling, gold up to 41 g/t Au in shear zones, and a reconnaissance drill result of 0.82 g/t Au over 3.1 metres.
Historic work has included surface sampling and limited reconnaissance drilling. Mineralised structures are reported over 500–800 metres, with parallel shears and untested depth potential. No Mineral Resource or Mineral Reserve has been defined, and further exploration is required to establish the continuity, width and grade of mineralisation.
