New Exploration Tools for Copper-Gold Porphyry Deposits with Advanced Argillic Alteration Zones

New report published: AME Roundup; Porphyry Vectoring Techniques in Advanced Argillic Altered Rocks of British Columbia

Vancouver, BC – January 31, 2022 – New tools have been developed to help direct mineral explorers towards copper-gold porphyry deposits in British Columbia.

Results from this research have been published at the AME Roundup 2022 conference. The project studied the zones of advanced argillic alteration that can form a blanket of clay and aluminous-rich minerals above and around an economic copper-gold porphyry deposit. Mineral exploration within these alteration zones is traditionally difficult because of the large size of the altered areas and subtle mineralogical changes that can be difficult to identify.

Three areas across BC's Northwest and North Central Regions were included in the study, though the techniques developed from the results could be applied to any similar deposit. Rock samples were analyzed by a range of techniques, with the observations providing a toolset that can support rapid and cost-effective mineral exploration of porphyry copper and related epithermal mineralization.

Geoscience BC Vice President, Minerals, Christa Pellett said: “Geoscience BC is excited to co-release this report with the University of British Columbia’s Mineral Deposit Research Unit.  The tools identified in this research will directly support the mineral exploration industry in BC and beyond as they explore for critical minerals.”

Farhad Bouzari, Mineral Deposit Research Unit said: “Results of this project highlight the effectiveness of mineralogical and geochemical data as cost-effective and easy to use exploration vectoring tools for exploring within and around advanced argillic altered rocks in British Columbia and elsewhere.”
