Geology of the Mount M'Clintock Map Area (105D/16), Southern Yukon Territory

The Mount M'Clintock map area, northeast of Whitehorse, is dominated by Middle Triassic to Jurassic sedimentary and volcanic strata of Stikinia with small portions of the Cache Creek and Yukon-Tanana Terranes. These assemblages were deformed prior to the mid-Cretaceous intrusion of three plutonic suites and the deposition of two suites of volcanic rocks.

Sedimentary rocks previously mapped as undifferentiated Lewes River and Laberge Group strata are separated into their respectve groups and further sub-divided into several members. Lewes River Group rocks form three units that are Carnian and older, Norian, and Upper Norian in age and are represented by siliceous siltstone and calcareous sandstone, conglomerate and limestone respectively. Laberge Group strata are divided according to lithology and dominated by siltstone-sandstone couplets and massive siltstone with lesser conglomerate and volcanogenic sandstone. Volcanic rocks previously mapped as Hutshi Group are divided into the dominantly mafic and submarine, MiddleTriassic Joe Mountain volcanic complex (JMVC) and the dominantly felsic and sub-aerial Mount Byng volcanic complex (BCVC). The volcanic and sedimentary rocks generally increase in age from Middle Triassic to Jurassic from west to east across the map area.

Plutons cutting these strata belong to the M'Clintock Lakes (120 Ma), the Whitehorse (115 Ma), and the Mount McIntyre (109 Ma) plutonic suites. The predominantly felsic fragmental rocks of the BCVC are genetically associated with the Byng Creek pluton of the Mount McIntyre plutonic suite. The BCVC is nested into the country rocks and its eastern margin and is preserved as the rim of a tilted caldera.

Strata of the Laberge and Lewes River groups are folded throughout. Wavelengths are on the order of approximately 1-2 km, but are much tigter in black siltstone units and adjacent to northwest-trending faults. Faults are ubiquitous throughout the map area and form three sets. North-trending faults are the most common. They are spaced a few kilometres from each other and dictate the physiography and drainage of the region. Northwest-trending faults, in the northeastern corner of the map area control the Teslin River valley and juxtapose Yukon-Tanana rocks with Stikinia. Older faults are dominantly east-trending but are terminated or reactivated by younger faults.

Copper (gold-molybdenum-tungsten) skarns and gold-bearing quartz veins are the two mineral deposit types most likely to be discovered in the map area. The source of the placer gold in Sheldon Creek is unknown but may be related to gold veins in the JMVC, BCVC, Sheldon Creek volcanics or the surrounding sedimentary rocks. Hydrothermal activity in the JMVC is characterized by orange weathering alteration, breccias, and carbonate veins. Cache Creek rocks in the southern part of the map area are targets for listwaenite associated gold veins.

Aggregate resource exploration using a process-depositional model of meltwater channel development in the Eagle Plains area, northern Yukon.

Yukon’s northern oil and gas basins remained unglaciated during the Pleistocene. The absence of coarse aggregate material generated by glaciation, coupled with continuous permafrost, has required expensive programs of crushing and hauling bedrock for road and infrastructure development. This study examines fluvial deposits associated with the late-Pleistocene Eagle River meltwater channel as potential sources of aggregate for regional development. In particular, it applies a process-depositional model of meltwater channel development to understand the distribution and potential quality of aggregate resources in the area. We identify three zones with meltwater channel development: (i) an upper erosional zone (~ 50 km) of scoured bedrock associated with initial development of the channel; (ii) a middle zone (~ 35 km) of coarse deposition on high terraces associated with initial channel incision; and (iii) a lower zone (~ 75 km) dominated by fine lacustrine and deltaic deposits that likely overlie coarse fluvial deposits with up to 30 m of clay, silt and sand.

Regional stream sediment geochemical data, Whitehorse area, southern Yukon (NTS 105D)

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.

Conventional reservoir petrophysical property assessment for 34 wells, Eagle Plain, Yukon (65°45’ to 67°30’ N; 135°50’ to 138°45’ W)

Petrel Robertson Consulting Ltd. was contracted by the Yukon Geological Survey through the Geological Survey of Canada (Natural Resources Canada) to undertake a quantitative petrophysical assessment of the petroleum exploration wells drilled in the Eagle Plain Basin of Yukon. The study was initiated to enhance the research of the Yukon Basins Project, a collaborative research effort among the Geological Survey of Canada, the Yukon Geological Survey and university partners, and funded by the Geo-Mapping for Energy and Minerals (GEM) 2008-2013 initiative. The purpose of the assessment was to highlight prospective conventional hydrocarbon accumulations, and generate input for use in future resource assessments.

More than 60 000 m of strata were analyzed in the study. Based on three sets of cutoff criteria, reservoir and pay intervals were identified. The results identify hydrocarbons in 19 stratigraphic intervals, in 29 of the 31 wells analyzed. The best conventional hydrocarbon potential, assessed by net pay thickness, proportion of total net pay, proportion of net pay to formation/member thickness, and proportion of reservoir rock filled with net pay, was identified in the Carboniferous stable platform tectonostratigraphic succession followed in order by a Lower Paleozoic platform carbonate horizon and Permian sedimentary rocks of the Ancestral Aklavik Arch. Less prospective are the Jurassic-Cretaceous Cordilleran and Devonian-Carboniferous Ellesmerian orogenic successions.

Preliminary investigation of geological controls on radon concentration in surficial sediment in Whitehorse, Yukon (NTS 105D/11, 14)

Although the presence of radon has been reported in Yukon, the controls on radon soil gas fluxes in Yukon have not been studied. Here we report 328 radon concentration measurements collected in surficial sediment at 30 sites throughout Whitehorse during the summer of 2020 for the purpose of examining the controlling factors. The sediment types include till, glaciofluvial sand and gravel, glaciolacustrine silt, fluvial sand and gravel, and eolian sand. Average radon concentrations were compared to bedrock lithology, thickness of surficial sediment, surficial sediment type, surficial sediment grain size distribution, sorting, sediment maturity, and soil moisture to determine the first-order geological controls. Pronounced interseasonal variation was observed, but intraseasonal summer readings were relatively consistent. Positive correlation is apparent between radon concentration and grain size distribution, as well as between radon concentration and soil moisture. Negative correlation is observed between radon concentration and sediment maturity, with till and weathered bedrock displaying the highest concentrations of radon. No appreciable correlation was observed with depth to bedrock or with bedrock type. Additional data are being collected to complete the analyses in order to establish which geological and environmental factors are primary controls on radon concentration in near surface sediments.

Thermal Maturation and Hydrocarbon Source Rock Potential of Tantalus Formation Coals in the Whitehorse Area, Yukon Territory

Tantalus Formation strata at the Whitehorse coal deposit host eight coal zones of moderate to high ash, high rank coal, that range in thickenss from 0.15 to 12.8 m. Vitrinite reflectance values (Ro rand) vary from 1.68% to 3.45%, corresponding to a variation in rank from low volatile bituminous to anthracite. As vitrinite reflectance values are less than 4.0%, the upper limit of dry gas preservation, the generation of coal bed methane is possible. The coals are composed of structureless vitrinite and lesser fusinite. Some samples have a melting or coking texture indicative of rapid heating, possibly by contact metamorphism from local intrusions. Coals in contact with a rhyolite sill exhibit a progressive decrease in reflectance with increasing distance away from the sill. The deposit is well situated with regard to infrastructural requirements to support the exploitation of the coal. At present drill indicated reserves are in excess of 182 125 tonnes (200 800 tons) and open in all directions. Extensive faulting at the Whitehorse coal deposit likely precludes the preservation of any hydrocarbons (gas) which may have been generated.

Total field magnetic, Wernecke Mountain Aeromagnetic Survey, NTS 106F (south half), Yukon

This map of the magnetic total field was derived from data acquired during an aeromagnetic survey carried out by Fugro Airborne Surveys during the period April 17, 2006 to August 26, 2007. The data were recorded using a split-beam cesium vapour magnetometer (sensitivity = 0.005 nT) mounted in the tail boom of a Cessna Caravan aircraft. The nominal traverse and control line spacings were, respectively, 800 m and 2600 m, and the aircraft flew at a nominal terrain clearance of 250 m. Traverse lines were oriented N30 degrees E with orthogonal control lines. The flight path was recovered following post-flight differential corrections to the raw Global Positioning System data and inspection of ground images recorded by a vertically-mounted video camera. The survey was flown on a pre-determined flight surface to minimize differences in magnetic values at the intersections of control and traverse lines. These differences were computer-analysed to obtain a mutually levelled set of flight-line magnetic data. The levelled values were then interpolated to a 200 m grid. The International Geomagnetic Reference Field was not removed from the magnetic total field.

Bedrock geology of the Duke River area, parts of NTS 115G/2, 3, 4, 6 and 7, southwestern Yukon

The Duke River area comprises Late Paleozoic arc volcanic and sedimentary rocks, Triassic basalts, carbonate and sedimentary rocks, overlain by Tertiary terrestrial sedimentary and volcanic deposits. These rocks are intruded by Upper Triassic to Miocene plutons, sills and dykes. Post-late Paleozoic uplift and erosion are suggested by the lack of Early Triassic rocks, as well as a higher degree of folding exhibited by the older stratigraphy. A subsequent, compressional episode thrust Paleozoic rocks over Triassic rocks and folded the strata into upright, to overturned, tight folds. This event is younger than the Upper Triassic to Cretaceous Tatamagouche succession, but older than mid-Cretaceous plutons. Post-Cretaceous, steeply dipping strike-slip faults dissect the area and include both extensional and compressional components. A recent compressional event is exhibited by Triassic rocks thrust over folded Tertiary strata. The structural complexity of the area is significant, as it affects exploration targeted at mineralized Upper Triassic ultramafic intrusions.

The Harlan property: A new sediment-hosted gold discovery in the Selwyn Basin, Yukon

The Harlan property is a significant new sediment-hosted gold prospect within the Selwyn Basin of east-central Yukon Territory. The property has a large, kilometre-scale surface gold-arsenic-antimony-mercury-bismuth anomaly within a thick sequence of Paleozoic Selwyn Basin shelf and off-shelf sedimentary rocks. A series of mid-Cretaceous, late-stage, Tombstone Suite, quartz-feldspar-porphyritic monzonite dykes and small plugs intrude these rocks. Two major mineralized zones have been defined: 1) the Vortex Zone, a thick package of strongly brecciated, silicified, and argillic-altered coarse clastic sedimentary rocks overlain by a thrust-faulted argillite member; and 2) the West Porphyry Zone, consisting of abundant mineralized and altered monzonitic dykes. Surface sampling over the Vortex Zone has defined a north-northwest-trending 1600 m by 700 m zone averaging over 500 ppb gold in soils, with rock sample values up to 6.5 g/t Au. Within this zone, an intensely brecciated area measuring 500 m x 300 m averages greater than 1 g/t Au in soils. A broad anomalous area was identified from surface sampling across the West Porphyry Zone, revealing gold-in-silt values up to 230 ppb and numerous rock chip samples over 1.0 g/t Au. No drilling has been done on the property to date. NovaGold Resources plans to complete detailed surface geological mapping, geochemical sampling, and geophysical surveys to refine drill targets for testing in 2000.
