This data package contains results for parts of the Whitehorse survey area (NTS 105D). This information has been provided in a variety of digital formats. PDF files include survey descriptions and details regarding methods, analytical data listings and summary statistics. Raw digital data of original field and analytical information plus new reanalysis results are included in Microsoft®Excel (XLS) format. NGR surveys were originally conducted in the Whitehorse map area in 1985 and covered parts of NTS map sheet 105D (Geological Survey of Canada, 1986). Stream sediment and water samples were collected from a total of 1003 sample sites. The work was undertaken by the GSC in conjunction with the Department of Indian Affairs and Northern Development, and the government of Yukon under the Canada-Yukon Mineral Development Agreement (1985-1989). As part of the 2014 Yukon Database Upgrade Project, original material collected from 930 sample sites were selected for reanalysis. Samples from 79 sites located in protected areas were not included. Representative 2 gram splits were successfully recovered from a total of 964 samples. Due to a deficiency of available material, 12 samples were not recovered. The samples were delivered to Bureau Veritas Commodities Canada Ltd. (Vancouver) and were analyzed by an ultra-trace aqua-regia digestion ICP-MS package for 53 elements.

Map presents an interpretation of the bedrock geology of the northern Whitehorse trough as extrapolated from field observations and a reflection seismic survey.

Whitehorse Trough is a frontier basin in south-central Yukon that is thought to contain gas and possibly oil. Over 400 samples from the Whitehorse Trough have been analysed by programmed pyrolysis and combustion, which together with coal rank, vitrinite reflectance, and the colour of microfossils indicate the following: the Povoas formation has no source rock potential; the Aksala formation is a poor source rock, probably gas-prone and postmature; the Richthofen formation is a poor to fair source rock, gas-prone and postmature; the Nordenskiold formation has no source rock potential; and the Tanglefoot and Tantalus formations are potentially good to very good source rocks, mainly gas-prone with a possibility of oil and mature. The Aksala and Richthofen formations are interpreted as spent source rocks, whereas the Tanglefoot and Tantalus formations are interpreted as potential source rocks and possibly effective source rocks. The most prospective areas for hydrocarbon exploration are Division Mountain, Tantalus Butte and Five Finger Rapids.

A placer mining and exploration compilation of parts of the Watson Lake and Whitehorse mining districts, southern Yukon Territory, Canada. This compilation includes the location, history and previous work, description of bedrock geology, surficial geology and mineralization, as well as lists of related references. Accompanying this report are four 1:250,000-scale maps (Watson Lake, 105A; Whitehorse, 105D; Teslin, 105C; and Wolf Lake, 105B) which display the locations of the placer occurrences discussed in the report.

Geology of the Whitehorse Copper Belt (NTS 105 D/11), southern Yukon. A compilation including a 1:25 000-scale geological map with marginal notes on bedrock geology, mineral occurrences, mineral deposits and grades of some mineral deposits.

This report discusses the distribution of intrusion related and other mineral occurrences in the Whitehorse map-area, Yukon. Mineral occurrences recorded in the Archer, Cathro and Associates, Ltd., Northern Cordillera Mineral Inventory have been classified according to deposit type and principal commodities then plotted on a lithologic map (1:250 000 scale) which is in part an updated version of the Geological Survey of Canada four mile map for the Whitehorse map-area by Wheeler (1961). New information added to the map includes: geology and geochronology of the Bennett Lake cauldron subsidence complex; geology of the Atlin Terrane; reinterpreted geology of the adjacent Laberge map-area and part of the Bennett and Atlin map-areas; a reclassification of geologic units in southern Yukon; reconnaissance mapping, classification and geochronology of granitic rocks in the Whitehorse map-area; and detailed stratigraphy of the Upper Triassic Lewes River Group with special emphasis on the Whitehorse Copper Belt and the associated Cu-Fe skarn deposits.
