Results of multi-sensor (gamma ray spectrometer, magnetometer) contracted, helicopter surveys flown July-September, 2000 (phase 1) and July-September, 2001 (phase 2) are available in a variety of digital and printed formats. This is a joint release from the Geological Survey of Canada (GSC) and the Yukon Exploration and Geological Services Division (EGSD). Flight lines were positioned every 500 m. The survey was funded by the Geological Survey of Canada through the Targeted Geoscience Initiative. GSC Open File 4311, EGSD 2002-17D contains 120 digital images (in PDF format): 10 1:250,000 maps and 110 1:50,000 maps for 10 variables.

Reclamation testing was carried out on 3 mineral exploration sites in Yukon: an alpine site at the Red Ridge property in the Whitehorse area, and 2 subalpine sites, a boreal forest site at the Nucleus property in the Carmacks area, and a site in moist permafrost at the Hawk propeerty int he Dawson City area.

A quantitative gamma-ray spectrometric and aeromagnetic helicopter-borne geophysical survey was completed by Fugro Airborne Surveys. The survey was flown from September 10 to October 14, 2008. The nominal traverse and control line spacings were 400m and 2400m respectively, and the aircraft flew at a nominal terrain clearance of 125m. Traverse lines were oriented at 0 degrees with orthogonal control lines.

This is a re-release of data collected and published as the Yukon GEOPROCESS FILE between 1994-1996. The data set is a compilation of information and knowledge on geological processes and terrain hazards in the Yukon Territory. The original work was carried out in three phases from 1992 to 1995. Contractors performed the work under the supervision of the Environmental Geologist, Exploration and Geological Services Division, Yukon Region, Indian and Northern Affairs Canada. The following individuals and companies were involved in carrying out the project: Mougeot GeoAnalysis, Aurum Geological Consultants Inc., L. Walton and C. Hart.

Stream sediment and water surveys were conducted in the Old Crow area of northwestern Yukon during the summers of 2004 and 2005. These surveys were carried out under a Joint Research Agreement between the Yukon Government (Oil & Gas and Mineral Resources Division of the Department of Energy, Mines and Resources) and the Federal Government, acting through the Earth Science Sector's Metals in the Environment Program. Analytical data accompany this document for 50 elements in stream sediments and 60 variables in waters from a total of 655 sites sampled in 2004 and 2005. National Geochemical Reconnaissance protocol was used for the collection, preparation and analysis of waters and silts.

Data were acquired during an airborne geophysical survey (gamma ray spectrometer, magnetometer and VLF-EM) carried out by Fugro. Funding was provided by the Government of Yukon. The survey was completed between July 29 and September 21, 2000.

Considerable research has been carried out into the reclamation and revegetation of disturbed lands in the Yukon, including operating and abandoned mines, and mineral exploration sites in the Yukon. Reclamation efforts on tailings have focused on methods to establish an initial vegetative cover on disturbed areas. Guidelines have been established by Kennedy (1993) and Hill et al. (1996) for the optimum mixtures of fertilizer and seeds (both agronomic and native varieties)¿. ¿.A relatively new and unique method of tailings processing and disposal that is being used at a few mines around the world is called dry stacking. This method of tailings disposal has the potential to provide many benefits to mining companies and affords numerous environment advantages that slurry deposits do not¿. ¿.The purpose of this proposed project was to research current practices in other jurisdictions and to examine the best approaches for encouraging vegetative establishment on dry stack tailings in norhtern environments, particularly for potential mine sites in the Yukon.
