Survey Description

Till samples were collected at 30 sites in 1999 around the Peddie kimberlite, Lake Timiskaming area, northeastern Ontario.  Four sites were sampled up-ice (north) of the kimberlite, and 26 sites were sampled down-ice (SW to SE).  The data are published in Geological Survey of Canada Open File 4262.  For comparison, the open file also includes data from 2 samples collected in a 1997 survey around the Peddie kimberlite and previously published in GSC OF 3775.
