Till sampling, NTS 55K/16, 65H/16, southern Nunavut, 1975 and 1976.
(requires an Internet connection)
In 1975, approximately 200 till samples were collected in the Heninga Lake area, near Padlei, approximately 150 miles southwest of Rankin Inlet (NTS 65H/16). The sampling was carried out in a zone of copper and nickel enrichment previously found in reconnaissance sampling.
Approximately 88 till samples were collected in 1976 near Rankin Inlet, Nunavut (NTS 55K/16). Samples were collected from mudboils on grids with closely spaced sample points near the former Ni-Cu mine at Rankin Inlet. Sampling density was between 5 and 100 samples per square kilometre. The purpose of the sampling was to map glacial dispersal patterns from known sources and to confirm and define by detailed sampling anomalies that were found by earlier reconnaissance sampling on one mile grids.
A summary of the work can be found in Geological Survey of Canada, Report of Activities, Paper 77-1A.

The geographic extent of the survey is defined by the following polygons:
Covers part of NTS 55K/16, the Rankin Inlet area, Nunavut. It is bounded to the northeast by Hudson Bay. The shaft of the abandoned nickel-copper mine at Rankin Inlet is located within the study area.
Covers part of NTS 65H, west of Heninga Lake in the Padlei area, Nunavut. It is bounded to the east by Heninga Lake.
