Summary(Plain Language Summary, not published)
This scientific presentation was given at the SEG-PDAC Student Mineral Colloquium during the 2018 Prospectors and Developers Association of Canada (PDAC) convention. It provides a description of the textural variations of Ni-Cu-(PGE) mineralization hosted within the Eagle¿s Nest deposit. This deposit is hosted in a narrow, subvertical, structurally-rotated komatiitic dike located in the Ring of Fire region of northern Ontario, and is adjacent to several world-class chromite deposits. The presentation is part of ongoing MSc research conducted through the Geological Survey of Canada's Targeted Geoscience Initiative to develop a genetic model of the Ni-Cu-(PGE) mineralization in the mafic to ultramafic Ring of Fire Intrusive Suite, and to also provide a better understanding of overall intrusion geometry within the suite.
