Till, Indicator minerals
Till sampling survey, NTS 31 M/5, Lake Timiskaming area, northeastern Ontario, 1999.
(requires an Internet connection)
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.
