brownfield exploration

PDAC 2026 will feature two technical sessions examining brownfield and greenfield exploration strategies. The brownfield session focuses on expanding resources around existing or past-producing mines, highlighting lower geological risk, faster timelines, and capital efficiency. Case studies include copper, gold, and IOCG systems in established districts. The greenfield session reviews recent discoveries and emerging districts, including gold, potash, copper-gold, and uranium projects. These presentations illustrate differing risk-return profiles, infrastructure requirements, and exploration economics. Together, the sessions demonstrate how brownfield extensions and greenfield discoveries both contribute to long-term mineral supply and reserve replacement across global jurisdictions. [more]

PDAC 2026 Technical Sessions outline how artificial intelligence and advanced geophysics are being applied in mineral exploration. The program includes an AI session covering computer vision, machine learning for structural modeling, and implementation considerations for large language models. Two geophysics sessions focus on integrated exploration case histories and newer methods, including magnetotellurics, inversion workflows, airborne geophysics analytics, and muon tomography. Regional technical sessions add examples from Latin America and brownfield exploration. Across the agenda, presentations emphasize multi-dataset interpretation, risk reduction, and operational constraints. The sessions collectively frame technology adoption as workflow-driven and incremental. This article summarizes sessions and key themes. [more]
