Summary(Plain Language Summary, not published)
Geomapping for Energy and Minerals (GEM) fieldwork during the 2017 and 2018 field seasons revealed that Boothia Peninsula and Somerset Island, north-central Nunavut, contain numerous scattered sulphide occurrences mostly associated with clastic supracrustal sequences and their melted derivatives. More than 50 variably sized rusty ± sulphidic outcrops were noted during ground traverses or spotted during helicopter flights. This report presents geochemical mineral assay analytical results for 31 samples collected from these gossanous localities. The data are tabulated (Appendix 1) and presented as graduated symbols on a series of elemental maps (e.g., Ni,Cu, Au) to highlight localities with elevated base- and precious-metal contents. A large subset of the samples collected through GEM yielded anomalous polymetallic mineral values that, while generally modest, demonstrate some economic mineral potential for base-metals in the region.
