Lodestar Minerals staked 186 more acres at Virgin Mountain after assays up to 14.68% TREO, securing a 5km heavy rare earth trend for drilling.
Lodestar Minerals expanded its Arizona rare earth project by 40% after rock chip assays returned up to 14.68% total rare earth oxide, the company said Wednesday.
The Australia-listed miner staked an additional 186 acres, bringing the total Virgin Mountain landholding to 661 acres across 32 mining claims. The expansion secures the full extent of a mapped heavy rare earth structural corridor, according to Lodestar.
Recent field work confirmed a five-kilometre trend of xenotime-hosted mineralisation. Assays returned high-grade results, including samples enriched in dysprosium and terbium – elements often flagged as critically undersupplied for magnets and defence hardware.
Lodestar noted the chip samples are selective and may not represent the broader zone.
“These results are among the strongest we have returned from Virgin Mountain,” CEO Coraline Blaud said. “Grades of this quality, dominated by the high-value heavy rare earths the market urgently needs, underline why we have moved decisively to secure more ground.”
With the corridor secured, Lodestar is preparing a high-resolution airborne radiometric and magnetic survey over the expanded area. The survey aims to map the shear-system structure and identify drill targets.
After the survey, the company plans ground-truthing and target prioritisation. Lodestar is also progressing permitting under Arizona rules for its first drilling programme.
