Compilation of historic geologic data can help identify deposits of unmined gold-bearing gravel and promote further exploration on under-explored ground. Archival documents of the Yukon Consolidated Gold Corporation (YCGC) contain detailed, accurate prospecting data, and can be used to identify dredge localities and production values. With dredge inefficiency and crude mining techniques, areas heavily worked in the past may contain both technogenic and remnant in situ gold-bearing gravel. These types of placer deposits have been the target for many miners on previously worked ground, but with the aid of historic data, these deposits can be identified and evaluated for their potential prior to any ground work. Although there are some limitations and challenges associated with the historic documents, the data contained within them can significantly support placer exploration in both mined and unmined areas of Yukon.
