Porphyry Copper Column: Characteristics and Exploration Implications
February 15 @ 3:00 pm - 5:00 pm
On February 15 (Thursday), 3 PM at the NIGS Seminar Room, the NIGS Lecture Series will feature a talk by Dr. Renato Bobis on “Porphyry Copper Column: Characteristics and Exploration Implications.” The poster and abstract are attached (and below). Zoom meeting details for the hybrid set-up will follow.
Dr. Renato Bobis holds a Bachelor of Science degree on Geology from the University of the Philippines and a PhD from James Cook University of Queensland. He is a member of the Society of Economic Geologists, and a CP (Geology) member of the Australasian Institute of Mining and Metallurgy. Dr. Renato Bobis is a successful economic geologist with expertise on prospectivity analyses, project identification, evaluation, exploration management and research. He has more than 35 years of academic and industry experience and has been involved in world-wide exploration, discoveries, resource development and research.
Feel free to disseminate this post. This talk is open to the general public. Coffee and biscuits will be available.
The NIGS Lecture Series is being held in partnership with the Iuvenis Orbis Geological Fraternity.
See you there!

Porphyry Copper Column: Characteristics and Exploration Implications.

Abstract
Porphyry copper deposits are the most important source for copper, contributing more than 60% of the annual world copper production and around 65% of the known total copper resource. A spectrum of deposit-scale geologic, geochemical-geophysical and geometric features and factors influence the size and/or grade of porphyry copper deposits. These characteristics, often occurring as clustered or aligned intrusion centres with affiliated hydrothermal breccias, polymetallic veins, hypogene upgrading-supergene enrichment have evolved in several ways, largely driven by the objective of finding more productive porphyry copper centres.
I synthesise here the alteration-mineralisation characteristics of a porphyry copper column and thence present scenarios on how these features/factors are applied in the exploration of porphyry copper centres.
