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.

The original reconnaissance surveys were undertaken by the Geological Survey of Canada as part of the Nahanni Integrated Multidisciplinary Pilot Project (1982).

W.D. Goodfellow directed Geological Survey of Canada activities related to geochemical methodologies, sampling and analytical specifications, and map and data release formats (1981).

GSC OF 3772 (D3772) was the product of a reanalysis program undertaken under the terms of the Canada/Yukon Geoscience Program (1999) with the participation of the Government of Yukon, the Department of Indian and Northern Affairs and the Geological Survey of Canada.

GSC Open File 4016/INAC OF 2001-12D is part of a series of Yukon open files in a standard format developed for the digital reissue of Yukon geochemical data originally published on paper.
