Maestro Digital Mine has launched its PoE-enabled SuperBrite Marquee Display for underground mines, using a single Ethernet cable via the Plexus network to deliver both electrical power and real-time data to headings and working faces. The LED display is designed for high-visibility production, ventilation and safety messaging in low-light, high-dust drifts where conventional power distribution is costly and complex. For engineers, PoE removes the need for separate 110/230 V feeds and local transformers, simplifying installation, certification and maintenance of digital signage underground.

GRX26’s inaugural Global Resources Innovation Expo programme will run over three days with eight plenary keynotes and more than 30 speakers focused on “where innovation meets implementation” in mining and resources. Headliners include former Australian foreign minister The Hon Julie Bishop on new rules of resource diplomacy and Jason Crusan, CEO of AROSE and former NASA director, on cross-sector lessons from space systems engineering. The industry-led agenda signals strong emphasis on deployable technologies, automation and decarbonisation pathways rather than purely conceptual R&D.

Codelco and Rio Tinto have signed a Memorandum of Understanding at the BMO Global Metals, Mining & Critical Minerals Conference to create a strategic framework for joint development of major mining investment projects in Chile. The collaboration is aimed at improving project development and execution performance, drawing on both companies’ experience with large-scale copper operations and complex brownfield expansions. For engineers, the move signals potential alignment on project delivery models, risk-sharing structures and technical standards across future Chilean underground and open-pit developments.
