Survey Metadata

In 1993, Caledonia Mining Corporation conducted an alluvial sediment survey on their Coronation Gulf, Tree River, Bathurst Inlet and Back River claims in central and western Nunavut and part of eastern Northwest Territories on mapsheets NTS 86O, 66E, F, 76K, M, N, 86K, N, O, P.  In the Coronation Gulf area, the Rae, Richardson, Coppermine, Napaaktcktok, Asiak, Kugaryuak Rivers were sampled.  In the Bathurst Inlet area, the sampling concentrated on the drainage basins of the Burnside, Mara, Booth, Hood and James Rivers. The Tree River and Back River were also sampled.  In all areas, a series of 100 kg samples were collected.

In 1994, bulk sampling was carried out in the Coronation Gulf area, but not in the Bathurst Inlet region as the kimberlite potential of the area was considered poor.  Emphasis was shifted from the Tree River alluvial diamond exploration to kimberlite pipe exploration in the Kikerk Lake region.

The samples collected in 1993 were gathered using a Venturi suction hose and in 1994, the more effective Explorer Jig system was used.  Sampling in both years was helicopter assisted.

The samples have been SEM checked and data are available.

The data can be found in Nunavut Assessment Report 083452.
