Core samples are submitted to the Saskatchewan Research Council geoanalytical laboratories in Saskatoon. The SRC facility is ISO/IEC 17025:2005 accredited by the Standards Council of Canada (scope of accreditation No. 537). The samples are analyzed for a multielement suite using partial and total digestion inductively coupled plasma methods, for boron by Na2O2 fusion and for uranium by fluorimetry.
