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.

MASPRO is working with underground mines to extend hydraulic cylinder and wear-component life by forensically analysing premature failures that often occur within days in high-load, high-contamination environments. Using teardown inspections, metallurgical assessment and seal and surface finish analysis, the company traces root causes such as side-loading, misalignment, poor lubrication and abrasive ingress rather than accepting short service intervals as “normal”. The approach is feeding back into redesigns of rod eyes, bearing areas and sealing systems, giving maintenance teams data to adjust operating practices and stocking strategies.
