“Since the initial White Gold discovery, over 20 junior mining companies have acquired land in the region which has been dubbed “The White Gold District”. However, companies focusing their attention solely on the White Gold District may be missing opportunities farther afield when considering the geological similarities to the broader mineralizing event that created the Dawson Range Mineral Belt”

“The results of this study provide evidence for a regional metallogenic event related to late cretaceous shoshonitic volcanism, which resulted in the development of epithermal gold and base metal-rich veins transitional between low and high sulphidation types. The intense alteration and paleo-magnetic resetting of pre-existing country rocks provide evidence for a large scale hydrothermal system through the southern Dawson Range driven by the Carmacks Magmatic Event” - Katherine Smuk 1999

“The similarity in structural geometry from NW to SE through the Dawson Range Mineral Belt indicate the presence of a much larger system than previously recognized, however the sources of the gold bearing fluids remain enigmatic” - Bennett, Colpron, Burke Yukon Geological Survey July 2010

“In Yukon, gold mineralization is related to the Carmacks volcanic units and coeval hydrothermal alteration. A genetic model linking gold mineralization to hot spot related hydrothermal activity is suggested. New exploration models, based on this linkage, may assist in the identification of additional gold mineralization in Yukon”. - S.T. Johnston et al - Yellowstone in Yukon - 1996
