Survey Description

In 1994, till samples were collected at 182 sites in the Westlake plain area, southern Manitoba.  At each site, two samples were collected: a 40 litre bulk till sample weighing approximately 70 kg and a 3 kg split.  The large sample was processed for kimberlite indicator minerals, and the 3 kg split was submitted for geochemical analysis.

The data are published in Manitoba Energy and Mines, Open File Report OF96-2.

The data are also part of two compilations in Manitoba Agriculture and Resource Development open files OF2020-2 and OF2020-5.

The geographic extent of the survey is defined by the following polygons:

  • Covers parts of NTS 62J (Neepawa), 62K (Riding Mountain), 62N (Duck Mountain), 62O (Dauphin Lake) and parts of 63B (Waterhen Lake), 63C (Swan Lake), the Westlake plain area, southern Manitoba.  It covers an area from Portage la Prairie in the south to just north of the unincorporated area of Mafeking and includes most of Lake Manitoba along its eastern edge.
