VEGA’s MINITRAC 31 radiometric sensors are being used in Madagascar to measure ore slurry density directly from the mine, providing non-contact readings through the pipeline wall under highly abrasive laterite nickel–cobalt conditions. The system operates reliably in tropical climate extremes and with variable solids content, where conventional differential pressure or nuclear gauges struggle with scaling, wear and calibration drift. For process engineers, more stable density data supports tighter control of slurry transport, thickener performance and downstream hydrometallurgical circuits.

Atlas Copco’s AIRCUBE modular compressor rooms replace conventional stick-built compressor houses on mines, arriving as pre-engineered containerised units with integrated ventilation, electricals and controls for rapid plug-and-play deployment. Units can be craned into position on simple concrete pads, connected to existing ring mains and power within days rather than the weeks or months typical for full civil works and building construction. For brownfield expansions and remote greenfield sites, this compresses project schedules, reduces on-site trades and simplifies future capacity upgrades or relocations.

Lake Victoria Gold’s Tembo project in Tanzania has reported an initial resource of almost 600,000 oz. gold adjacent to Barrick’s Bulyanhulu mine, including 2.69 million indicated tonnes at 1.16 g/t and 13.33 million inferred tonnes at 1.12 g/t across the Ngula 1, Nyakagwe Village and Nyakagwe East near-surface deposits. A 5,000-metre infill drilling campaign will target Ngula 1, already drilled to about 200 m depth and hosting over half of inferred ounces, while a toll-milling deal is being advanced with Nyati Resources’ 500 t/d plant on a Tembo licence. Combined with the shovel-ready Imwelo project, expected to average 3.7 g/t in its first two years, the company is positioning for small-scale multi-asset production in Tanzania.
