"The Geological Survey of Canada, as part of its review of gold metallogeny in the Abitibi had the opportunity to visit the Upper Beaver site with Agnico Eagle Mines limited Upper Beaver exploration team in early June 2019. This visit, and the observation of recent core from the mineralized zones exposing Au-rich quartz-carbonate veins containing molybdenite, led Agnico Eagle Mines limited and the Geological Survey of Canada to sample the Au-Mo veins for Re-Os geochronology on molybdenite. These Au-rich quartz-carbonate-molybdenite (± chalcopyrite-pyrite) veins represent a style of mineralization that differs from the bulk of the ore at Upper Beaver. The objective of this study was therefore to improve the current knowledge of the deposit by providing age constraints on a style of gold mineralization that is distinct from the magnetite-chalcopyrite Au-rich and quartz-calcite ± chalcopyrite-magnetite-molybdenite-Au styles of mineralization. Analyses were undertaken in collaboration with the University of Alberta. The results are briefly reported and discussed here"--Introduction, page 1.
