Reference number : GC-2017-Q1-00530, amendment number : , agreement type : G, recipient legal name : Dare, Sarah (University of Ottawa)|Dare, Sarah (Université d’Ottawa), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Engage Grants for Universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : Volcanogenic massive sulfide (VMS) deposits are exploited primarily for Zinc (from the sulfide mineral,_x000D_
sphalerite - ZnS) and Copper (from the sulfide mineral, chalcopyrite - CuFeS2). VMS deposits formed from_x000D_
hot, hydrothermal fluids circulating through volcanic rocks on ancient seafloor (similar to black smokers on the_x000D_
seafloor today). However, some VMS deposits contain unusually high amounts of the mineral magnetite_x000D_
(Fe3O4), rendering significant parts of the deposits uneconomic. Magnetite is thought to form by replacement_x000D_
of the sulfides. However, the detailed mechanism/s of this replacement process, and why the replacement of the_x000D_
entire deposit is nearly complete, in some cases, are not well understood. Therefore the Company-specific_x000D_
problem is to understand better the origin of massive magnetite in their VMS deposits at Matagami, Quebec._x000D_
To address this scientific problem, the proposed project aims to provide new constraints on the formation of_x000D_
magnetite in VMS deposits through a combined study of the petrography and trace element chemistry of_x000D_
magnetite and sulfides from Matagami VMS deposits. We will use the innovative technique of laser ablation_x000D_
ICP-MS to obtain high quality, in-situ trace element data. This is a rapidly expanding field of research within_x000D_
Mineral Deposit studies. The expected outcomes of the project will lead to 1) a better understanding of the_x000D_
replacement process/es and timing of magnetite formation and 2) identification of the type of hydrothermal_x000D_
fluids involved and their possible relation to new style of mineralization in the Mining Camp. The current (and_x000D_
last) operating mine of Matagami is owned by the Company and will last only a few years, making exploration_x000D_
for the next mine critical for this northern mining town. Being able to better understand the role of the_x000D_
magnetite in the VMS deposits of Matagami will help better define exploration criteria that will contribute to_x000D_
finding new exploration targets. A number of other VMS deposits in Eastern Canada contain similar massive_x000D_
pods of magnetite, and thus the results of this study are directly applicable and beneficial to other_x000D_
