Airborne electromagnetic/magnetic survey data were acquired for the area between April 17 and April 30, 2015. The aircraft flight elevation was maintained at a nominal ground clearance of 83 m. Aircraft navigation used a 12-channel NovaTel dual frequency GPS. A vertically mounted video camera was used to record images of the ground. The radar height was recorded ten times per second using a Sperry unit and the barometric altitude was recorded ten times per second using a Motorola altitude transducer. The magnetic data were recorded 10 times per second using a Scintrex CS-2 cesium-vapor magnetometer.

This GIS dataset is a Yukon-wide compilation of surficial geology lines derived from 13 published and unpublished 1:250,000 scale surficial geology maps produced by the GSC and Yukon Geological Survey. Surficial geology line features captured in this compilation include: surficial geological contacts; glacial limits; glacial landforms such as cirques, aretes, eskers, meltwater channels and moraines; and non-glacial landforms such as faults, lineaments, landslides, and escarpments.

This report outlines the results and the conclusions of a study of the mineral potential of the Eagle Plains area. The accompanying mineral potential map ranks the different tracts according to their relative order of mineral potential, from highest to lowest. The highest ranking rocks occur on the flanks of the Richardson Anticlinorium which corresponds to the flanks of the southern Richardson Mountains. Other contributions resulting from this study include: complete geochemical coverage of the area provided by a new Regional Geochemical Survey and reanalysis of silt samples of a pre-existing survey; the discovery of several new mineral occurrences; the discovery of rocks of possible volcanic origin, previously undocumented in the area; and modifications to the pre-existing geology maps.

This map of the first vertical derivative of the magnetic field was derived from data acquired during an aeromagnetic survey carried out by Goldak Airborne Surveys during the period of May 16 to July 1, 2009. The data were recorded using a split-beam cesium vapour magnetometer mounted in the tail boom of a Piper Navajo aircraft. The nominal traverse and control line spacings were 400 m and 2400 m, respectively, and the aircraft flew at a nominal terrain clearance of 150 m.

Yukon Geological Survey re-analyzed stream sediment sample pulps from GSC's archives in Ottawa. As a next step to improving the dataset, two of the areas covered by the recently-released Open Files were selected for further data processing to add value to the raw data. Catchment areas were delineated for each sample, and data were modeled to isolate the geochemical signatures that are characteristic of the known mineral deposit types in the area. This report and the accompanying series of maps present the results of this ?value-added? analysis of raw stream sediment geochemical data. The project was funded by the Canadian Northern Economic Development Agency (CanNor) through their Strategic Investments in Northern Economic Development program.
