The regional stream survey for Little Nahanni River (NTS 105I) was conducted during the summer of 1981.
This report presents analytical and statistical data for gold and 25 other elements obtained by re-analyzing stream sediments from 984 sites sampled at an average density of one sample per 11.7 km². Original field and analytical data for stream sediments and waters are also included in this report.
