The Samuels Lake intrusion, located in the central western Quetico Subprovince, is similar to an array of mafic-ultramafic intrusions along the northern boundary of the subprovince. These intrusions are referred to in the literature as the Quetico intrusions, and are accompanied by Cu-Ni-PGE mineralization and characteristically contain clinopyroxenite and minor pegmatitic phases. The Samuels Lake intrusion is elliptical in form and displays concentric zoning with a wehrlite core surrounded by a hornblendite zone and pyroxenite exterior. The PGE mineralization is associated with the occurrence of sulphides, especially chalcopyrite, in altered pyroxenite and wehrlite. High values of PGE appear related to high-temperature, late-magmatic, hydrothermal alteration. 1 Contribution to the Western Superior NATMAP Project 1 Resume : L’intrusion de Samuels Lake, dans le centre ouest de la Sous-province de Quetico, ressemble a un reseau d’intrusions mafiques-ultramafiques le long de la limite nord de la sous-province. Ces intrusions, designees «intrusions de Quetico» dans la documentation scientifique, sont accompagnees de mineralisations de cuivre, de nickel et d’elements du groupe du platine et se caracterisent par la presence de clinopyroxenite et de phases pegmatitiques mineures. L’intrusion de Samuel Lake est de forme elliptique et presente une zonation concentrique avec un coeur de wehrlite entoure d’une zone de hornblendite et d’une zone externe de pyroxenite. La mineralisation en elements du groupe du platine est associee a la presence de sulfures, surtout la chalcopyrite, dans de la pyroxenite et de la wehrlite alterees. Les teneurs elevees en elements du groupe du platine semblent etre associees a une alteration hydrothermale tardi-magmatique de haute temperature.
