FLSmidth has launched the KREBS® OSA, an online particle size analyser that measures particle size distribution continuously and in real time directly in the process stream, rather than via manual sampling and lab assays. Installed on the grinding circuit, the unit gives immediate feedback on mill and cyclone performance, allowing operators to adjust variables such as feed rate, water addition and classification cut size without waiting for batch results. For plant metallurgists, this supports tighter control of grind size, more stable circulating loads and reduced risk of off-spec flotation feed.

PYBAR, a Thiess company, has secured new underground development contracts at Southern Cross Gold’s Sunday Creek gold‑antimony project and Agnico Eagle’s Fosterville gold mine in Victoria, plus a contract extension at MMG’s Rosebery polymetallic mine in Tasmania. The work packages centre on decline and level development, ground support installation and associated services for high‑grade narrow‑vein orebodies, including gold‑antimony and zinc‑lead‑copper mineralisation. For geotechnical and mining teams, the awards signal continued demand for specialist underground contractors capable of managing complex ground conditions in mature brownfield mines and emerging critical minerals projects.

Exploration activity across Australia remains strong, with Alkane Resources, Artemis Resources and Ark Mines progressing gold, copper and rare earths prospects via drilling, project funding and metallurgical test work. Alkane is advancing targets around its Boda–Kaiser porphyry deposits in the Northern Molong Belt, New South Wales, using recent diamond drilling and geophysical surveys to refine copper–gold mineralisation trends. Artemis and Ark are pushing early-stage programmes that will influence near-term resource definition drilling strategies and metallurgical flowsheet options for complex ore types.
