Till, Indicator minerals
Till sampling survey, Contwoyto Lake area, NTS 76E (N½), Nunavut, 1996.
(requires an Internet connection)
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.
