Epithermal-type deposits are small, high-grade gold and/or silver ± base metal deposits that formed shallowly in the upper crust and are frequently associated with hydrothermal fluids related to deeper emplaced, large tonnage, low-grade precious metal ± base metal porphyry deposits. Bringing the deeper emplaced deposits to surface requires processes such as erosion of overlying rocks. Consequently, epithermal systems that formed at approximately the same time as porphyry systems are often eroded. However, in the Toodoggone district, northern British Columbia, numerous epithermal and porphyry systems of similar ages have been preserved. This project aims to determine the factors responsible for bringing porphyry deposits to surface to while still preserving the easily erodible epithermal deposits. The proposed internships will comprise a significant component of a MSc research project being conducted at the University of British Columbia. Ultimately, the findings from this research project will help guide exploration strategies at partner organization by identifying where both the preservation and exhumation of epithermal and porphyry deposits occur in the district.
