The Analytical Industries Inc. GPR-3500 Portable Purity Oxygen Analyser is a battery-powered unit for field and plant verification of enriched oxygen streams from 0–100 per cent, with selectable high-purity ranges such as 90–100 per cent O₂. Designed for portable use around gas plants, pipelines and on-site storage, it targets purity checks on oxygen-enriched process gas rather than trace-level safety monitoring. For mining operations relying on oxygen for leaching, smelting or cutting, it offers on-the-spot confirmation of gas quality without returning samples to a fixed analyser.

Geoscience Australia has mapped a 1000km continental-scale magmatic arc beneath the Delamerian project region spanning South Australia, New South Wales and Victoria, identifying concealed potential for critical minerals, copper and gold in previously under-explored terrane. Delivered as the first deep-dive study under the Federal Government’s 35-year Resourcing Australia’s Prosperity initiative, the work integrates deep-crustal geophysics and geochemistry to image mineral systems buried beneath thick cover. For explorers, the results materially expand prospective search space below cover sequences rather than in outcropping belts.

Active risk management in Australian mining is shifting towards real-time, technology-driven controls that separate people from heavy plant in shared work zones. New systems from suppliers such as Aptella integrate collision avoidance, proximity detection and geofencing around haul trucks, loaders and autonomous fleets, using on-board sensors and wearable tags to trigger alarms or automatic slow-downs. For geotechnical and operations teams, this means redesigning traffic flows, exclusion zones and training to match digital risk maps, with the aim of making “zero harm” credible rather than aspirational.
