Iltani Resources reports impressive assay results from its Orient Silver-Indium project in Queensland. Robust reverse circulation drilling has revealed high-grade silver-indium intersections across multiple zones, paving the way for an imminent Mineral Resource Estimate. This exploration milestone underscores strong growth potential for the company in a major, underexplored deposit.

Iltani Resources Limited has released its final assay results from a series of reverse circulation drillholes (ORR091 to ORR095) at its Orient Silver‐Indium Project in northern Queensland. The updated results confirm that the high‐grade core of the deposit, which spans roughly 900m by 350m, continues to deliver strong intercepts of silver, lead, zinc, and indium mineralisation. Notable intercepts include multiple zones such as a 7-meter section grading 117.4 grams per tonne silver equivalent (Ag Eq.), with a high‐grade 1-meter interval registering as much as 455.8 g/t Ag Eq. Other results include intersections such as 19m at 59.7 g/t Ag Eq. and 29m at 47.3 g/t Ag Eq., reinforcing the potential to define a sizable, open-pittable resource. Drilling over the past two years has involved 57 RC holes and 3 diamond holes, accumulating nearly 13,000 metres of drilling in the Orient West area. The technical work has confirmed continuity of the mineralised veins both along strike and down dip—with intersections reported to extend over 200 to 300 meters below the surface—supporting the view that Orient West is Australia’s largest and highest-grade silver-indium deposit. The detailed assay protocols, based on industry-standard reverse circulation sampling and rigorous QA/QC procedures, underpinned the calculation of metal equivalents using the formula Ag Eq. = Ag + (Pb x 35.5) + (Zn x 50.2) + (In x 0.47), using a 30 g/t Ag Eq. lower cut-off. Iltani’s independent mining consultants are now using the completed drilling data to model and estimate an initial JORC-compliant resource, with the Orient West resource update targeted for completion by the end of July. In parallel, the Orient East drilling program has been concluded with results pending, and a further Orient East resource is expected in September 2025. The company also plans to restart drilling later in July to test high-priority geophysical anomalies, potentially enhancing both tonnage and grade in the established deposit areas. From an investor sentiment perspective, the news carries a bullish tone. The strong and continuous high-grade intercepts, combined with an aggressive resource estimation program and ongoing exploration efforts, underline the potential for significant value creation. However, on the bearish side, uncertainty remains, as the exploration target is conceptual in nature and further drilling is required to confirm the mineral resource. As such, while the technical indicators are promising, the ultimate economic success will depend on the forthcoming resource estimate and follow-up exploration outcomes.
