PRE-ORDER: "Porphyry Deposits of the Northwestern Cordillera of North America: A 25-Year Update" - Available December 2020.
CIM’s Special Volume 57 is the third volume in a series of books dedicated to porphyry deposits of the northwestern Cordillera and is timely, given the increased levels of exploration for precious and base metals seen throughout western British Columbia, southwest Yukon and southern Alaska over the past number of years. With the increasing importance of copper in the sustainable future of global society, this volume presents a series of papers focused on porphyry deposits, the major source of this green metal globally, structured into two sections.
Section 1 comprises informative and detailed reviews of the porphyry-related metallogenic evolution of key belts throughout the Cordillera, possible linkages between porphyry and epithermal deposits in some important districts in British Columbia, greenrock exploration vectors in porphyry deposits, and the potential geological significance of platinum group elements that commonly occur in many porphyry deposits in British Columbia. Section 1 concludes with reviews of recent technological developments in the fields of geometallurgy, and tailings management as relevant to porphyry copper ores. The papers in section 1 provide a solid framework for the descriptions of individual porphyry deposits in Section 2. Some deposits are formally documented for the first time (e.g. IKE, Kwanika and Gnat Pass) and others benefit from updated geological descriptions (e.g., the Kerr-Sulphurets-Mitchell-Iron Cap-Snowfield cluster of deposits, which are all well represented).
This Special Volume will be of interest to geologists, explorers, miners and anyone wanting to learn more about this core part of the mining landscape in Canada and Alaska.
