Project title:

Towards a generic model for localized, highly-enriched orogenic gold deposits

Project outline:

The Klondike Gold District is world famous for the huge amount of placer gold that has been recovered since the great gold rush of 1896. Exploration and research has been driven by the disparity between the 20+ million ounces of placer gold versus only 1240 ounces recovered from in situ occurrences. The largest of these lode occurrences is located on the Lone Star ridge which is flanked by the extremely rich Eldorado and Bonanza creeks (7Moz). Development of the geological understanding of the area has been hindered by complex lithologies, multiple phases of deformation, deep weathering and a lack of exposure. This PhD project aims to characterise gold bearing veins across the Lone Star area in order to illuminate the controls on the hydrothermal system. The current deposit model for the Klondike mineralization is inferred to be ‘orogenic’ however, the specific elements of the source- transport-trap model remain unclear.


Detailed understanding on the controls and paragenesis of mineralisation in the Lone Star area

Discuss why the area is so highly enriched in gold within the Klondike and also worldwide

This study will contribute to the wider understanding of small but rich orogenic gold deposits
