Global Case Studies on Copper and Gold Mineralization to Shape the Agenda at proEXPLO 2026

Lima, February 25, 2026.– The 15th International Congress of Prospectors and Explorers, proEXPLO 2026, will feature as one of its central highlights a keynote lecture by Alan Wilson, President of the Society of Economic Geologists (SEG), who will present a series of international case studies on different styles of Cu-Au mineralization.

From Theory to the Field

During his presentation, Dr. Wilson will share concrete examples of deposits he has worked on in Alaska, British Columbia, Peru, and Australia, aiming to demonstrate how tectono-magmatic models can guide crucial exploration decisions and significantly improve the probability of success in projects associated with potassic intrusive complexes.

“We expect the main takeaway to be a better understanding of the diversity of alteration and mineralization styles associated with certain gold-rich copper porphyry deposits linked to alkaline intrusive complexes. I refer to Au-Cu porphyry and epithermal Au mineralization associated with silica-undersaturated alkaline intrusive rocks, such as that recently discovered in the back-arc of central Peru,” he explained.

The lecture will be structured around real-world experiences in systems related to potassic magmatism, where significant variations in alteration styles and metal associations are observed. These case studies will illustrate how understanding deep geodynamic processes and their expression in the upper crust translates into practical criteria for selecting and prioritizing exploration targets.

Dr. Wilson emphasizes that certain gold-rich copper porphyries, particularly those genetically linked to potassic igneous rocks, develop in specific tectonic environments. “Understanding the factors that control the generation of these magmas allows us to refine the targeting process and maximize the chances of discovery,” he noted.

The geologist added that in a global context where copper is strategic for the energy transition and the security of critical metal supply, the rigorous application of tectono-magmatic models represents a competitive advantage for exploration companies.

For emerging geoscientists, Dr. Wilson recommends observing as many rocks as possible and frequently visiting mines and projects to understand what economically viable mineralization truly looks like, beyond the mere presence of mineralization.

Professional profile

Alan Wilson is an economic geologist and independent consultant with extensive experience in mineral exploration and resource evaluation worldwide. He has advised more than 50 mining and exploration companies across the Americas, Europe, the Middle East, and Australia, participating in projects at various stages, from early assessments to resource definition.

With this keynote lecture, proEXPLO 2026—taking place from May 4 to 6, 2026, at the Centro de Exposiciones Jockey in Lima—reaffirms its commitment to high-level technical content, connecting international expertise with today’s exploration challenges.
