Iltani Drills High-Grade Silver-Indium Zones at Orient West

Strong Silver-Indium Hits Reinforce Resource Potential

Iltani Resources (ASX:ILT) has delivered another round of compelling assay results from its ongoing reverse circulation (RC) drilling program at the Orient West area of its flagship Orient Silver-Indium Project in North Queensland. Eleven drill holes (ORR148 to ORR158) have intersected high-grade, indium-rich massive sulphide veins alongside broad zones of silver, lead, zinc, and indium mineralisation at depths suitable for open pit mining.

Standout intercepts include a remarkable 1 metre at 192 g/t silver and 925 g/t indium in ORR148 from 104 metres downhole, along with other high-grade hits such as 1m at 358 g/t silver and 213 g/t indium in ORR151 and 1m at 811 g/t indium in ORR158. These results underscore the project's status as Australia's largest known silver-indium deposit, with the potential to become a significant global supplier of indium concentrate.

Broad Zones Support Open Pit Development

Beyond the narrow high-grade veins, the drilling has also revealed multiple broad intercepts of mineralisation. For example, ORR148 returned 17m at 37 g/t silver and 88 g/t indium from 97 metres, including 8m at 69 g/t silver and 180 g/t indium. Similarly, ORR151 yielded 6m at 93 g/t silver and 54 g/t indium from 47 metres, with higher-grade intervals within.

These wider zones at shallow depths enhance the project's open pit mining prospects and provide valuable data for upgrading the current JORC Mineral Resource Estimate (MRE). Iltani has completed 65 holes (12,297 metres) so far in this 110-hole program, with assays regularly submitted and more results expected in the coming months.

Drilling Targets and Resource Upgrade Plans

The recent drilling focused on infill and step-out holes designed to increase grade, tonnage, and confidence in the existing Orient West resource. Notably, holes ORR156, ORR157, and ORR158 tested previously underexplored Veins 5 and 6 at shallow depths, successfully intersecting mineralisation and expanding the known vein package.

Managing Director Donald Garner highlighted the critical role of indium in technology applications and noted that the ongoing drilling is closing gaps between Orient East and West, extending mineralisation along strike, and improving resource confidence. The company plans to continue infill drilling to 50-metre section spacing before testing northeast and southwest extensions, as well as other regional targets within the Herberton Project.

Orient Project: A Rich Silver-Indium System

The Orient Silver-Indium Project forms part of Iltani's broader Herberton Project, encompassing approximately 370 square kilometres in a historically prolific mineral field. The deposit is a large-scale epithermal system with high-grade sulphide veins rich in silver, indium, lead, and zinc. Historical metallurgical test work supports the recovery of these metals into payable concentrates.

The current JORC resource stands at 34.2 million tonnes at 110.4 g/t silver equivalent, split between Orient East and West. An additional exploration target of 15.4 to 18.8 million tonnes at 95 to 117 g/t silver equivalent remains to be converted through further drilling.

Next Steps in Exploration and Development

Iltani is advancing its drilling campaign with two RC rigs active, including infill drilling at Orient East and testing of the Link Zone between the East and West deposits. Following completion of the current program, the company will assess priorities for further drilling to extend mineralisation and explore new targets such as the Boonmoo and Union Jack prospects.

With assay results flowing steadily and resource confidence building, these developments set the stage for forthcoming scoping and feasibility studies that will assess the economic potential of open pit mining at Orient West.
