Survey Description


In 1985, stream sediment orientation surveys were carried out in the proposed expansions to Nahanni National Park Reserve, Northwest Territories as part of a resource assessment.  In the Ragged Ranges area, 58 stream silts were collected in an area extending from Lened (skarn tungsten deposits) to Vulcan, a Zn-Pb showing.  In the Nahanni Karst area, 55 stream silts were collected around the Prairie Creek (Cadillac Mine) Ag-Pb-Zn vein.

The orientation survey was conducted to test sampling procedures, to identify potential problems (effects of topography and drainage, glaciation, contamination, presence of organic material) and to determine the geochemical signature of mineralized areas.

The data are published in Geological Survey of Canada Open File 1686.

Data from this survey are also included GSC Open File 5344, a resource assessment carried out in a larger area than was previously considered for expansion.
