Reference number : GC-2017-Q3-00525, amendment number : , agreement type : G, recipient legal name : Bouvier, Audrey (The University of Western Ontario), 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 : New gold ore deposits are increasingly hard to find for mining companies such as Lake Shore Gold_x000D_
Corporation (a wholly owned subsidiary of Tahoe Canada / Tahoe Resources Inc.) in Timmins, Ontario. Key_x000D_
parameters in gold exploration are to understand their relationship to geological processes and obtain precise_x000D_
knowledge of the deposits' ages. Gold deposits are challenging to age date because they may be formed later_x000D_
than the host intrusions and the origin of the auriferous fluids can be associated with the intrusion itself,_x000D_
metamorphism or from deeper parts of the crust or mantle. Moreover, elements used for long-lived radioactive_x000D_
decay systems do not partition well into gold. Neighbouring minerals are not always reliable either as they may_x000D_
have crystallized in the presence of different fluids or are minerals pre-dating the mineralization itself. As a_x000D_
consequence, at the West Timmins mine (TWM), there is currently no chronology established for gold_x000D_
mineralization. Only the age of the host rocks of the veins are available (Barrie, 1990) and may pre-date_x000D_
mineralization by tens of million years. Gold is found in veins next to minerals such as scheelite (CaWO4) and_x000D_
titanite (CaTiSiO5) at TWM. Following a successful visit of Lake Shore in 2016 using a NSERC Connect_x000D_
grant, when we discussed with the company what geochemical and geochronological tools we can use for_x000D_
analyzing scheelite, we propose here to constrain the source of metals, geological processes associated with the_x000D_
formation of gold veins, and determine their radiometric ages. Knowing when and how many events were_x000D_
responsible for gold mineralization is critical to build a "footprint" of the geological processes responsible for_x000D_
gold deposition in Timmins. Our results will provide constraints on potentially areas of future exploration for_x000D_
