Résumé(disponible en anglais seulement)
During the 2008 field season, eleven till, six lodgepole pine and seven Engelmann spruce outer bark samples were collected near a porphyry Cu-Mo deposit (Gibraltar Mine) in central British Columbia. The purpose of this survey is to test the effectiveness of these sampling medium at detecting mineralization in regions where bedrock mineralization is covered with glacial sediments. Various fractions of the till matrix and bark samples were submitted for geochemical analyses. Our results demonstrate that minor elements (Au, Ag, Ba, Cu, Mo, Te, Zn) and one major oxide (Al2O3) are enriched to various degree in till down-ice from the Gibraltar ore bodies compared to background concentrations reported from the Bonaparte Lake map area south of the mine. Similarly, Cu and Mo are more enriched in lodgepole pine and Engelmann spruce outer bark near Gibraltar compared to the Bonaparte survey. These results attest to the utility of till and tree outer bark geochemical surveys as means to vector towards porphyry mineralization such as that contained in the Gibraltar ore bodies.
