Survey Description


In 1985 and 1986, rock samples were collected in the northern part of western Labrador in the following areas: Birch Lake, André Lake, Martin Lake, Marion Lake, Dyke Lake, Astray Lake, Charlie Lake, Gauthier Lake and Marble Lake.  The purpose of the study was to assess the non-ferrous mineral potential of the region.

Major elements were determined by XRF, and ferrous iron by titration.  Trace elements were determined by various methods including DCP, XRF, INAA.  Au by fire assay preconcentration with AAS or INAA finish.

The data are published in Geological Survey of Canada Open File 2370.

The geographic extent of the survey is defined by the following polygons:

  • Covers part of NTS 23J/16 (Hollinger Lake) in western Labrador and part of Quebec.  It is bounded to the north by the Quebec-Labrador border.  The northern part of Martin Lake is located within the study area and Lac Voixpreux is located just east of the study area.

  • Covers part of NTS 23I/13 (Marion Lake) in western Labrador.  The western edge of the study area is located just east of longitude 66°W and Marion Lake lies within the study area.  It is bounded to the northwest by Moss Lake.  The centre of the study area is located approximately 7 km west of the Labrador-Quebec border.

  • Covers a very small part of NTS 23I/13 (Marion Lake) in western Labrador.  It is bounded to the east by Gauthier Lake.  The study area is geographically located approximately halfway between longitude 66°W and the Quebec-Labrador border.

  • Covers part of NTS 23I/12 (André Lake) in western Labrador.  Most of André Lake lies within the study area.  The centre of the study area is located approximately 6 km south of the Quebec-Labrador border and 12 km west of longitude 65.5°W.

  • Covers parts of NTS 23I/4 (Timmins Lake), 23I/5 (Wade Lake) and a very small part of 23J/8 (Marble Lake) in western Labrador.  The Ashuanipi River covers a large part of the study area.  It is bounded to the southwest by Giasson Lake.  Latitude 54.25°N cuts the study area roughly in half.

  • Covers parts of NTS 23J/7 (Menihek Lakes), 23J/8 (Marble Lake), 23J/9 (Cavers Lake) and 23J/10 (Stakit Lake) in western Labrador.  It is bounded to the east by longitude 66°W.  The centre of the study area is located approximately 50 km southeast of Schefferville, QC.  Astray, Marble and Dyke lakes lie within the study area.
