Survey Description
In 1999, several shallow trenches were excavated into the McLean kimberlite in the Lake Timiskaming kimberlite field, northeastern Ontario. Fourteen till samples were collected from 15 pits between 20 m up-ice (north) and 1 km down-ice (south) of the kimberlite. Samples of weathered and fresh kimberlite were also collected. The data are published in Geological Survey of Canada Open File 1762.
Sampling Procedure
Fifteen pits 2-3 m deep were excavated using a backhoe to collect the samples.
