University Supported Placer Research

Placer gold as a pathfinder for Cu-Au porphyries (Leeds University)


Field work for this project included collection of placer gold grains from downstream of Casino porphyry deposit. Chemical analyses of these samples have been completed, and a comparison of the results to gold grains in Casino drill core reveals the distinct porphyry signature of the gold is preserved during erosion and transportation.

Alternative placer minerals from Indian River (Leeds University)


The mineralogy of heavy minerals collected with gold from the Indian River appears to be unique in the Klondike. Specifically, cassiterite and ilmenite have been confirmed in concentrations of 4 and 2%, respectively at a locality on the Indian River downstream of the mouth of Quartz Creek. At present, the lithological source of these minerals is unclear and the range of distribution of these minerals in the placers and their potential dispersion patterns are unknown. This project will evaluate whether minerals other than gold are present in economically significant concentrations in Indian River placer deposits.
