Survey Description


In 1994, 143 one kg till samples were collected from the southern and northwest Contwoyto Lake map area, Northwest Territories and Nunavut.  An additional 27 ten kg samples were collected at some of the sites for regional kimberlite indicator mineral and gold grain analysis.  The till and gold data are published in GSC Open File 3387.  The KIM data are published in GSC Open File 3386.

Data Description:

Paper report; text and data files on diskette (WP, Excel).

Quantities Analysed:

<0.002 mm fraction by ICP-AES after aqua regia digestion (3HCl:1HNO3) for 28 elements; <0.063 mm fraction by INAA for 35 elements (OF 3387).

Geochem Maps Available:

Proportional symbol maps showing dispersal of selected elements.

Other Analyses:

Heavy mineral concentrate for gold grain counts (GSC OF 3387) and kimberlite indicator minerals (GSC OF 3386)
