Red Metal Limited says leach testing at its Sybella rare earths project near Mount Isa in Queensland supports a heap-leach processing pathway. Across reports, the company points to column or heap-leach style tests using weak-acid leaching, which it says achieve strong recoveries from coarse ore materials. Red Metal also describes the feed as including coarse saprock and transitional ore, stating these material types are delivering “stunning” or strong recoveries in the tests. The West Australian Business report specifies that the results come from column leach testing of coarse ore using weak-acid conditions, and frames the findings as evidence for a potentially lower-cost approach. The company’s statements focus on the technical outcomes of the leaching work and how they may inform subsequent project development. The reports do not describe production volumes, timelines, or financing impacts, and they do not provide independent confirmation beyond Red Metal’s claims.
