Digitizing and spatially analyzing historic YCGC drill data from Dominion Creek: a pilot project
공공데이터포털
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.
Analyzing historic drilling data to investigate gold distribution on lower Hunker Creek and Klondike River
공공데이터포털
The Yukon Consolidated Gold Corporation (YCGC) tested, mined, and documented placer gold resources in the Dawson region from 1923 to 1965. The company was established to acquire the holdings of other dredging operations and smaller companies in the Klondike, and during the time it was active in Yukon, YCGC produced a robust collection of maps and textual documents including drilling results, dredge reserves, thawing and stripping layouts, and dredging limits. This paper uses historic YCGC data to summarize gold distribution characteristics in Hunker Creek and builds upon previously published summaries of YCGC data. Attributes of 1005 YCGC drill holes and shafts along lower Hunker Creek and a short section of the Klondike River were digitized, compiled, and analyzed in a Geographical Information System (GIS). A raster analysis of the digitized data allows for interpretation and examination of surficial material thicknesses and gold distribution in the project area and identifies potential prospects for further exploration.
