Survey Description

During the summer of 1988, helicopter and truck-supported stream sediment and water sampling was carried out in south central Yukon.  Samples were collected at an average density of one sample per 13 km2 throughout the 11,100 km2 survey area.  Sample site duplicate samples were routinely collected in each analytical block of twenty samples.  The data are published in Geological Survey of Canada Open File 1962.  This report includes data for the north half of map sheet 105M collected in 1987 and previously released in 1988 as OF 1650.  The samples from NTS 105M were subsequently analysed for Bi and Se and the new data released in GSC Open File 3685.

This survey was carried out using National Geochemical Reconnaissance (NGR) protocols.
