Geofile 2006-1 describes a till geochemical survey covering roughly 3500 km2 over the eastern part of the Anahim Lake map sheet (NTS 93C).  Miocene basalt and glacial sediments cover much of the area and these add to the challenge of identifying targets of economic interest.  The result is that there are only five mineral prospects known in the region.  A total of 330 till samples were analysed for trace elements including gold and copper, and major oxides by a combination aqua regia digestion – inductively coupled plasma emission spectrometry (ICP-ES), instrumental neutron activation (INAA) and lithium metaborate fusion – ICP-ES.  Anomalous results highlight the existing Clisbako and Oboy Au prospects and outline several other areas with a potential for additional epithermal Au mineralization.
