The program’s technical sessions cover environmental issues, geotechnical engineering, mineral processing, mining, Mexico-focused projects, geology, and new projects. Topics include Arizona’s WOTUS status; machine-learning-based representative sample selection; open-pit slope stabilization; alkaline-flush treatment of metals-impacted water; numerical mine modeling, geotechnical monitoring, and tailings-storage-facility stability; flotation technologies, ADR processes, and SAG mill sizing; mine-permitting timelines, pump failures, electrical maintenance, water treatment, and autonomous operations; and mineral resources, drilling confidence, tailings water balances, and mine-project development. Featured presentations address Resolution Copper’s next chapter and large-load electrical growth in Arizona. New-project updates cover the Santa Cruz Ivanhoe Mine, Florence Copper, Faraday Copper’s Redhawk Complex, and Hudbay CopperWorld. The program also includes a student poster session and a student pitch session. Pre-conference programming includes a course on proposed NI 43-101 disclosure changes and a Women in Mining workshop on boundary-setting skills.

Technical presentations cover the Pleasure Bay Interceptor Recovery Tunnel, the Palisades Tunnel Project, Ellicott City flood resilience, East River Tunnels rehabilitation, and ground stabilization for the Hudson River Tunnels. Other topics include Italian high-speed rail tunnel design and construction, the Manhattan Tunnel Project and ground freezing, jet-grouting safe havens on the Lower Olentangy Tunnel Project, the BART Silicon Valley Phase II extension, and the MWRA Metropolitan Water Tunnel Program. The program also includes a project update on the Gateway Hudson Tunnel and an update on the U.S. tunneling industry, including major projects, construction methods, market drivers, and trends.
