Positive Govn't Report Seems like really good news coming from Geological Survey of Canada research in the region as well.
This report presents analytical data from sphalerite, galena, chalcopyrite, and arsenopyrite grains recovered during recent surficial sampling programs in the region southwest of the headwaters of the Mackenzie River, Northwest Territories. Many samples were found to contain high numbers of sulphide mineral grains for which there is no known local source. Lead and S isotopic determinations were conducted to evaluate if the sulphide grains could have been transported from the nearest known source, the Pine Point Mississippi Valley-type district, or whether the grains are sourced from yet-to-be-discovered bedrock mineralization. Lead isotopic values from galena grains (207Pb/204Pb = 15.57 to 15.70; 206Pb/204Pb = 18.00 to 18.20) indicate a more radiogenic source than the Pine Point district and are, therefore, likely to have been locally sourced. Sulphur isotopic values from galena grains range from 0 to 27 permille delta-34S, comparable to Pine Point and other Mississippi Valley-type deposits globally, indicating that similar styles of mineralization may occur in the region. Chalcopyrite delta-34S values range from -22 to +28 permille, indicating that the grains are sourced from either sediment-hosted Cu or Manto-style mineralization. Arsenopyrite delta-34S values indicate a sulphur source similar to orogenic gold deposits near Yellowknife, Northwest Territories, and are likely derived from the Canadian Shield, north of the study area. |
