Financial support for this project was provided from a Natural Sciences and Engineering Research Council of Canada (NSERC) Collaborative Research and Development Grant to S.J. Piercey. Additional funding was provided by the NSERC-Altius Industrial Research Chair in Mineral Deposits (supported by NSERC, Altius Resources Inc., and the Research and Development Corporation of Newfoundland and Labrador) and an NSERC Discovery Grant to S.J. Piercey.
