"Convergent margin-related magmatic deposits hosted by ultramafic-mafic intrusions are becoming an increasingly important global resource of Ni-Cu-PGE. In the northern Canadian Cordillera, a sub-class of ultramafic-mafic intrusions, known as the Alaskan-type intrusions, are hosted within the accreted arc terranes of the North American continental margin. These intrusions have long been recognized for their chromite-associated PGE mineralization potential. However, their potential to host significant Ni-Cu-PGE sulfide mineralization and to be used in efforts to reduce greenhouse gas emissions through permanent carbon mineralization is becoming increasingly studied. This report describes the main lithologies and field relationships observed at the Wrede Creek and Lunar Creek Alaskan-type intrusions in British Columbia during recent fieldwork"--Abstract.
