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. |
