Iltani Achieves 13x Upgrade in Silver-Indium Ore Sorting Tests at Orient Project [VIDEO]
Iltani Resources' TOMRA XRT ore sorting test work at the Orient Silver-Indium Project has confirmed proof-of-concept, achieving up to 16x grade upgrades and 96% mass rejection — results that could materially reshape the project's economics.
Key Takeaways
- TOMRA's XRT ore sorting test work at Orient has confirmed proof-of-concept, with the high-grade sample delivering a consistent 2x upgrade across silver, indium, lead, and zinc alongside 58% mass rejection.
- The low-grade sample produced upgrade factors of up to 16.1x for indium and 11.5x for zinc with 96% mass rejection, demonstrating the technology's ability to concentrate material that would otherwise be uneconomic.
- Results are based on screened 6–25 mm fractions only — the fines fraction generated by RC chips was excluded and will be evaluated in future bulk sorting and flowsheet test work.
- Iltani is planning a seven-hole PQ diamond drilling programme to generate approximately 700 kg of sample for large-scale bulk sorting trials at TOMRA's Sydney facility as the next concrete milestone.
- The Orient Silver-Indium Project hosts Australia's largest known silver-indium deposit at 62.5 Mt at 81.5 g/t Ag Eq., with an additional exploration target of 15.4–18.8 Mt at 95–117 g/t Ag Eq. yet to be converted to resources.
