Survey Description

The purpose of this till sampling survey was to define anomalous heavy indicator mineral trains detected by geophysical surveys. A total of 319 samples were collected on the Diavik claim block in the Lac de Gras area, Northwest Territories.

This helicopter supported program was conducted in mid-summer with crews of two collected till samples at various spacing. The preferred sample sites were mud or frost boils.

The data was SEM checked by R.L. Barnett Geological Consulting in London, Ontario.

The data can be found in Nunavut Assessment Report 084049.
