Survey Description


In 1996, 112 one kg till samples were collected from the northern Contwoyto Lake map area, Nunavut.  An additional 25 ten kg samples were collected at some of the sites for regional kimberlite indicator mineral and gold grain analysis.  The till and gold grain data are published in GSC Open File 3654.  The KIM data are published in GSC Open File 3768.

In addition to the 112 sites where samples were collected, glacial striae were measured at 70 sites to the north (NTS 76L).
