The Archaean Yilgarn Craton is composed mainly of granite, with mafic, volcanic and sedimentary greenstone rocks. It is one of the world s principal mineral provinces, with considerable resources of primary and supergene Au, sulfide-hosted and lateritic nickel, bauxite, as well as a wide range of other commodities.

From 1973 until 2002, Sherritt Gordon Mines Ltd. and later Hudson Bay Mining and Smelting, extracted copper and zinc ore from volcaniclastic and siliciclastic sequences of the Rusty Lake Greenstone Belt at the Ruttan Mine near Leaf Rapids, Manitoba, Canada. [Pg.347]

The Big Lake Cu-Zn-Ag-Au voicanogenic massive sulphide (VMS) occurrence is hosted in mafic-ultramafic strata of the Schreiber-Hemio greenstone belt near Marathon, Ontario (Fig. 1). This VMS is unusual in that it is one of a few documented VMS occurrences in sequences lacking felsic volcanic or volcaniclastic rock. [Pg.205]
