Orient West Drilling Yields Up to 995 g/t Silver Equivalent in New Assays

Robust Drilling Results at Orient West

Iltani Resources Limited (ASX, ILT) has announced a series of impressive assay results from its recent reverse circulation drilling campaign at the Orient West segment of its flagship Orient Silver-Indium Project in North Queensland. Drillholes ORR086 through ORR090 have returned multiple broad zones of high-grade silver and indium mineralisation, with some intercepts reaching exceptional grades, such as 1 metre at 945.4 grams per tonne silver equivalent in ORR086 and 1 metre at 995.1 grams per tonne silver equivalent in ORR089.

These results confirm the continuity of mineralised veins both along strike and at depth, highlighting the potential for a substantial resource. The mineralisation remains open at depth, suggesting further upside beyond the current drilling extents.

Progress Towards a JORC Resource Estimate

With the completion of the Orient West JORC Infill drilling program, Iltani has engaged independent consultants Mining One to model the data and estimate an initial JORC-compliant Mineral Resource. The company aims to release this resource estimate by the end of July 2025, a critical milestone that will underpin future development and investment decisions.

Meanwhile, drilling at the adjacent Orient East area has also been completed, with assay results pending. A JORC Resource estimate for Orient East is expected by September 2025, further expanding the project’s resource base.

Strategic Exploration and Expansion Plans

Iltani is not resting on these achievements. The company has received final data from a detailed geophysical survey (VTEM) and is working with Mitre Geophysics to model this data and identify high-priority targets. Drilling of these geophysical anomalies is planned to commence towards the end of July, aiming to add further tonnes and improve grade by testing extensions beyond the currently defined mineralised zones.

The Orient Silver-Indium Project is shaping up as Australia’s largest and highest-grade known silver-indium deposit, with significant potential for both open pit and underground mining operations. The high-grade massive sulphide cores identified in the drilling provide confidence in the project’s economic viability.

Context and Outlook

Located near Herberton in Queensland, the Orient project benefits from a rich history of exploration and a geological setting conducive to precious and base metal mineralisation. Iltani’s methodical approach, combining detailed drilling, geophysical surveys, and rigorous resource modeling, positions it well to unlock the full value of this asset.

As the company advances towards formal resource declarations and further exploration, market participants will be watching closely for the upcoming JORC Resource releases and the results of the new geophysical target drilling.
