"Supracrustal rocks of western Melville Peninsula form the Prince Albert Greenstone Belt, which is comprised of rocks dated 2.9 Ga and attributed to the Prince Albert Group, a distinctive lithostratigraphic unit of the Rae Craton. The belt is subdivided into three supracrustal packages based on field relationships and lithological associations. The snake supracrustal package which is comprised mainly of mafic to intermediate subaqueous metavolcanic and metavolcaniclastic rocks with lesser meta-ultramafic flows/sills and metavolcaniclastic rocks, outcrops at the base of the succession. The Borealis supracrustal package consists of felsic to intermediate, brecciated to massive metavolcanic rocks all containing quartz phenocrysts. The Triangle Lake supracrustal package is dominated by mafic to intermediate metavolcanic rocks intercalated with banded iron- formations and subordinate felsic to intermediate metavolcaniclastic rocks. During mapping, the discovery of a nickel showing in a meta-ultramafic intrusion and of a silver-zinc gossan within metavolcaniclastic rocks highlights the mineral potential of the Prince Albert Greenstone Belt"--Abstract.
