American Rare Earths’ Halleck Creek project in Wyoming has secured a Seed Translational Acceleration of Research (STAR) award via the University of Wyoming’s NSF Accelerating Research Translation programme to study byproducts and tailings from rare earth extraction. The work, led by Tyler Brown at UW’s School of Energy Resources, will assess technical viability, processing requirements and end-use applications for these materials and their impact on project economics. Halleck Creek metallurgical tests have already upgraded ore from 0.34% to 3.72% TREO, removing 93.5% of non-rare earth material early so only 6.5% requires further refining.

Northern Star Resources is tightening cost discipline and targeting higher productivity across its Australian gold portfolio after a “challenging” period, with particular emphasis on its Kalgoorlie and Yandal operations and integration of the KCGM Super Pit. The company is pushing mine-planning optimisation, fleet efficiency and mill throughput improvements at processing hubs such as Kanowna Belle and Thunderbox, while scrutinising unit costs per ounce. For contractors and suppliers, the shift signals closer attention to drilling productivity, equipment utilisation and ore-handling performance benchmarks on existing brownfield sites.

New Murchison Gold has logged a fourth straight month of rising output from its Crown Prince underground mine in Western Australia, following the first production blast at the newly developed Crown Prince lode. The operation is ramping up stoping and ore haulage from fresh development headings, feeding higher-grade material into the existing New Murchison processing circuit rather than building new plant. For mine planners and geotechs, the sustained lift signals stable ground conditions and successful sequencing of new stopes, with scope to refine drilling, blasting and backfill strategies as production scales.
