Assessing the role of small-scale structures in controlling auriferous fluid flow: Nadaleen trend, Yukon.
Carlin-type gold deposits (CTGDs) are large, high-grade gold deposits named after the world renowned occurrences in Nevada. Despite their economic importance, agreement on how they formed is still lacking. We are undertaking an integrated geological and geochemical study of CTGDs in the Nadaleen trend, Yukon, to better define the hydrological regime that controlled their formation. The proposed Mitac internship will form part of the overall study performing detailed analysis of small scale features that were potential fluid flow pathways for hot gold-bearing hydrothermal fluids. This work, combined with previous work studying the deposit geology and architecture, will be used as a framework to collect samples for future laboratory analysis. Ultimately, the data and samples collected by the intern will provide the partner organization with an improved understanding of how the deposits formed and this will benefit future exploration for CTGDs.
