Surficial Geology of Granite Creek (part of NTS 105M/14 and 105M/15)

The Granite Creek map area includes the southwestern section of the Gustavus Range. This area hosts summits approximately 2000 m in elevation. Granite and Albert creeks drain into Roop Lakes, through the wide, u-shaped lower Granite Creek valley. Keystone Creek flows in a narrow, bedrock-controlled valley. Lower Granite creek flows through the middle of the valley, depositing modern fluvial gravel and a blanket of organic material on the floodplain. Till from four alpine sources, as well as from the Cordilleran Ice Sheet (CIS), blanket the lower valley and intermix with glaciolacustrine sand and silt. Glaciolacustrine sediment can also be found capping moraines, and on valley walls above lateral moraines deposited when the CIS advanced up lower Granite Creek valley. Glaciofluvial gravel forms a proglacial fan where the former Granite Creek alpine glacier terminated and meltwater channels mark most former ice margins of the CIS. Till from the most recent glaciation is found in alpine glacier and Cordilleran Ice Sheet moraines, as well as in cirque valleys as blankets and veneers where preserved. Loess forms blankets on most gentle slopes, which allows for its preservation. Colluvium veneers, blankets, and fans form below steep slopes with active rockfall. Bedrock outcrops along steep cirque headwalls and in cirque valleys, as well as in Keystone Creek where fluvial downcutting processes are active. Stone stripes formed by frost heaving are found on gentle slopes. Flat upland surfaces host weathered bedrock and mud boils.

Total magnetic field, Eagle Plains Aeromagnetic Survey, NTS 116-I (south half), Yukon

This map of the total magnetic field was derived from data acquired during an aeromagnetic survey carried out by EON Geosciences Inc. in the period between April 10, 2009 and September 16, 2009. The data were recorded using split-beam cesium vapour magnetometers (sensitivity =0.005 nT) mounted in each of the tail booms of a Piper Navajo and a Cessna 206 aircraft. The nominal traverse and control line spacings were, respectively, 800 m and 2 400 m, and the aircraft flew at a nominal terrain clearance of 250 m. Traverse lines were oriented N90°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 (IGRF) was not removed from the magnetic field.

First vertical derivative of the magnetic field, Aeromagnetic Survey of the Nisling River Area, NTS 115 J/5, 6, Yukon

This high sensitivity aeromagnetic survey was carried out by Goldak Airborne Surveys (Goldak) on behalf of the Geological Survey of Canada (GSC) between January 25th and March 26th, 2011. Aircraft equipment operated included three cesium vapour magnetometers, a GPS real-time and post-corrected differential positioning system, a flight path recovery camera, VHS titling and recording system, as well as radar and barometric altimeters. All data were recorded digitally in GEDAS binary file format. Reference ground equipment included two GEM Systems GSM-19W Overhauser magnetometers and a Novatel 12 channel GPS base station which was set up at the base of operations for differential post-flight corrections.

Eighty two flights (including test and calibration sorties) were required to complete the survey block. A total of 37,999 line kilometres of high resolution magnetic data were collected, processed and plotted. The traverse lines were flown at a spacing of 400 m with control lines flown at a separation of 2400 m. Nominal terrain clearance was specified at 100 m above ground.

Volcanic-hosted epithermal gold-sulphide mineralization and associated enrichment processes, Sixtymile River area, Yukon Territory, Canada

The upper Sixtymile River area is located approximately 128 km west of Dawson City, Yukon. Lithology in this area consists of Precambrian to Paleozoic metamorphic rocks, Paleozoic ultramafic rocks, Middle Jurassic pegmatitic and aplitic dikes, Upper Cretaceous porphyritic dikes and volcanic rocks with intercalated sedimentary rocks, Quaternary alkaline basaltic dikes and Quaternary alluvial sediments.

Precious metal occurrences in these volcanic rocks are divided into two types, based on differences in local distribution, petrology and wall rock alteration: a gold-bearing pyrite-arsenopyrite type and a silver-bearing galena-sphalerite type. Both types are characterized by four stages of mineralization.

Revised geological map of Livingstone Creek area (NTS 105E/8)

This map presents an interpretation of the bedrock geology of the Livingstone Creek area that has been revised from a previous Open File map (YGS OF2005-9). The revised interpretation was guided by the acquisition of a detailed VTEM Plus geophysical survey over the area in spring 2016 (YGS OF2016-34 and 35; 200 m line spacing). The detailed magnetic data were particularly useful for increasing the accuracy of contact locations, and identifying additional structures. The electromagnetic survey identifies a number of conductors across the area, some of which remain unexplained (see Colpron et al. in YEG 2016 for discussion). Bedrock exposure is locally hindered by Quaternary glacial and fluvial sediments, particularly in the South Big Salmon valley. Projection of the geology is guided by the geophysics in areas of extensive cover.

Matt Berry property, southeastern Yukon

The Matt Berry deposit consists of roughly concordant layers of massive galena, sphalerite, pyrrhotite and chalcopyrite in Paleozoic phyllite. Drill-indicated reserves in 1979 were calculated at 533 434 tonnes grading 6.1% Pb, 4.8% Zn and 102.9 g/t Ag. The mineralization appears to have replaced the host phyllite along a narrow shear zone which strikes northnorthwest and dips at a moderate angle to the east. Geochemical and geophysical surveys in 1987 outlined a new exploration target 1 km along strike to the southeast.
