LITHOPROBE Slave-Northern Cordillera Lithosphere Evolution (SNORCLE) Transect
Winter Road Data Acquisition



The winter road (red dashed line) runs 600 km from the eastern end of the Ingraham Trail to Echo Bay's Lupin Mine on COntwoyto Lake. The road provides access to BHP's diamond mine and DiaMet's property at Lac de Gras. There is a 20 km extension to the Jericho kimberlite pipe being studied by Canamera Geological and Lytton Minerals. The Lupin Mine was closed in January, 1996, and accordingly access beyond Lac de Gras is limited.

Project Overview.....

Vehicle access of the Slave craton is very limited, and Echo Bay's winter road, which runs from Tibbit Lake (east end of Ingraham Trail) to the Lupin gold mine on Contwoyto Lake, provides a logistical opportunity to extend the geophysical observations from around the southwest corner of the Slave to well into the interior. In particular, the winter road affords the possibility to cross the Sleepy Dragon Complex and the Contwoyto Terrane, and to map electrically the lateral variation of the crust and sub�crustal lithosphere across the Slave craton.

MT along the winter road is an affordable geophysical method for obtaining information on the regional�scale lateral variation of the Slave's lithosphere, and will contribute significantly to the objectives of the SNORCLE transect. The winter road has a total length extent of 600 km, and with a station spacing about 1.5 times that on the Yellowknife to Rae portion of the transect, which was 10 km, would require a total of 40 MT sites along it to characterize the substructure electrically. The results should provide an improved picture of the assembly of the Slave Province and allow evaluation of models such as that of Helmstaedt and Schulze (1989) and Kusky (1989) etc.

Obvious questions to be addressed are:


EM Activities.....

Pilot phase undertaken in March-April, 1998

Press for full-sized map (178 Kb)
Acquisition at a total of eleven (11) sites from Tibbit Lake to MacKay Lake, with three of these at the southern end of the line, and the other eight on an east-west profile from northern Gordon Lake to MacKay Lake. Site locations shown on map as black squares. Other sites are from the SNORCLE 1996 MT data acquisition (yellow circles) and the 1998 Slave Lakes experiment (red stars)
