Iltani Resources Limited has delivered standout high-grade silver and base metals drill results from its Orient West program in North Queensland. These promising intersections reinforce its potential as one of Australia’s largest silver-indium deposits, boosting investor interest in the company’s future resource estimates.

Iltani Resources Limited has reported a series of encouraging drill results from its Orient Silver‐Indium Project in Herberton, North Queensland. The recent infill reverse circulation drilling program delivered several high‐grade intersections from holes ORR078 to ORR085, with intercepts that underline the broad continuity of shallow mineralisation in the high-grade core area. Among the highlights, ORR078 returned an interval of 45 meters averaging 75.6 g/t silver equivalent, including noteworthy 1-meter segments reaching over 340 and 540 g/t silver equivalent. In addition, holes ORR082 and ORR084 recorded exceptional 1-meter intercepts grading 1334.8 and 1478.3 g/t silver equivalent respectively, with complex multi-element contributions from silver, lead, zinc and indium. The drilling program was designed to validate the continuity and extent of a high-grade core within a roughly 900 by 350 meter target zone. Early results support the company’s view that the Orient deposit could evolve into a significant open pit resource, while also providing potential for underground mining at deeper levels. The technical work follows a strict JORC-compliant methodology, with assays calculated on a 30 g/t silver equivalent lower cut and a silver equivalent formula that incorporates weighted recoveries of lead, zinc and indium. The company also detailed its robust sampling, quality control and sub-sampling protocols as part of its comprehensive reporting. Iltani Resources Limited is on track to deliver a JORC-compliant resource estimate for Orient West by the end of July, with further drilling underway at Orient East expected to yield additional resource figures in September 2025. The extensive program, which has now completed over 100 reverse circulation holes and more than 21,000 meters of drilling, supports an initial Exploration Target concept of approximately 74 to 100 million tonnes grading 55 to 65 g/t silver equivalent – including a higher-grade core that could represent an additional 20 to 24 million tonnes at 110 to 120 g/t silver equivalent. On the bullish side, these drill results provide tangible evidence of the deposit’s high-grade continuity and significant scale, reinforcing market expectations for a robust future resource upgrade. The technical indicators, such as consistent high-grade intercepts at shallow depths and an effective geophysical targeting strategy, point toward a promising large-scale silver-indium asset that could attract further investments. Conversely, while the assay data are impressive, the resource estimate remains conceptual until complete assay results from additional drillholes are received, and further drilling is required to refine the continuity and true widths of the mineralisation. The inherent exploration risks, including potential variability in recovery rates and the extended timeline for a full Mineral Resource Estimate, provide a note of caution for those assessing the near-term valuation and trading outlook.
