Gold in lake sediments in the Caniapiscau area, Côte-Nord Region

New analyses of lake sediments carried out in 2006 in the Caniapiscau area have led to the identification of 108 areas with anomalous gold values, which represent new prospecting targets. The element associations observed in these anomalous areas suggest that there is potential for the following types of gold mineralization:

Element associations

Type of mineralization

Au-Fe-U

Olympic Dam-Kiruna

Cu-Mo-Au-Ag-Se

Porphyritic deposit

Au-W

Gold-bearing quartz vein

Au-Ag-Se

Quartz vein without sulphides

Au-As-Sb

Roberto

Au-Ag-Se-W-Bi-B

Skarn



Nearly 6100 samples were processed by ACME Analytical Laboratories. Gold and silver were reanalyzed using a better detection limit, while niobium, bismuth, antimony and tungsten were analyzed for the first time. These trace elements are particularly useful in prospecting for gold.

In 2006, the Ministère des Ressources naturelles et de la Faune, in cooperation with the Ministère du Développement économique, de l’Innovation et de l’Exportation, the Centre local de développement de Caniapiscau and the firm Exploration Québec-Labrador reanalysed lake-sediment samples collected in the 1980s. The sediment samples were from almost all over the Caniapiscau RCM’s territory, north of the Manicouagan reservoir.

The Caniapiscau area analyses are accessible via SIGEOM.
