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.

Blue Moon Metals is acquiring 33 tungsten and antimony projects on BLM and Forest Service lands in the western U.S. in a US$20.5 million cash-and-shares deal, adding a 1% NSR royalty and annual holding costs of about US$162,000. The portfolio includes historic high-grade tungsten assets such as the Oregon mine in Colorado (5,000 tonnes at 14.51% WO₃) and Wildhorse Canyon in Idaho (7,461 tonnes at 0.62% WO₃) as potential direct-shipping feed to the Springer processing complex in Nevada, plus five antimony projects grading 2–10% stibnite, marking Blue Moon’s first move into antimony.

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.
