Survey Description
In 2012, approximately 105 till and 76 esker samples were collected in the Mary Frances Lake-Whitefish Lake-Thelon River area, Northwest Territories. A till sample was taken approximately every 100 square km and an esker sample was taken approximately every 10 km. At each till site a 15 kg sample was taken for heavy mineral recovery, a companion 1 kg sample for geochemical analysis, 50 pebbles for pebble counts, and a 100 g sample for pXRF analysis.
The data are published in the following Geological Survey of Canada Open Files:

| 7408 | pXRF data for till and esker samples |
| 7540 | indicator minerals from till and esker samples |
