An update from Pioneer Lithium Limited ( (AU:PMM) ) is now available.
Pioneer Minerals has reported preliminary metallurgical test work from historic tailings at the Springfield Tungsten Mine that shows tungsten grades can be materially upgraded by up to 17.6 times using conventional gravity-based processing. Testwork produced concentrates grading up to about 3.27% WO3 and confirmed that tungsten is hosted in dense mineral phases concentrated in finer particle sizes, providing valuable insights for processing strategies across the broader North Pine Project.
These results support an ongoing metallurgical recovery program and underpin a near-term work plan that includes reopening site access, conducting electromagnetic geophysical surveys, and advancing permitting for Phase 1 drilling at Springfield. The company is also preparing applications for potential U.S. government funding initiatives aimed at strengthening domestic critical mineral supply chains, which could enhance project economics and strategic positioning if successful.
