Iltani Reports Multiple High-Grade Silver-Indium Intercepts in Latest Drilling
Iltani Resources has completed its JORC infill drilling program at the Orient West Silver-Indium Project in Queensland, delivering multiple high-grade assay results that confirm mineralisation continuity and set the stage for an initial JORC Resource estimate by July’s end.
- Completion of JORC infill drilling at Orient West
- Multiple high-grade silver-indium intercepts from drillholes ORR091 to ORR095
- Mineralisation continuity confirmed over 900m by 350m high-grade core area
- Initial JORC Resource estimate targeted by end of July 2025
- Further resource estimation at Orient East expected in September 2025
Completion of Infill Drilling Marks a Milestone
Queensland-based silver and base metals explorer Iltani Resources Limited (ASX, ILT) has announced the completion of its JORC infill drilling program at the Orient West Silver-Indium Project, part of its broader Herberton Project in North Queensland. The recent assay results from drillholes ORR091 to ORR095 reveal multiple zones of high-grade silver-indium mineralisation, reinforcing the company’s confidence in the project’s potential.
Robust Assay Results Highlight Mineral Continuity
The drilling program, which included 57 reverse circulation holes and 3 diamond holes totaling nearly 14,235 metres, targeted a 900m by 350m high-grade core area. The assay results demonstrate consistent mineralisation continuity both along strike and down dip, with notable intercepts such as 7 metres at 117.4 grams per tonne silver equivalent (Ag Eq.) from 131 metres in ORR091, and 11 metres at 122.4 g/t Ag Eq. from 83 metres in ORR095. These results confirm the presence of multiple intersecting vein systems with associated stockwork mineralisation, many at shallow depths, suggesting potential for an open pittable resource.
Towards a JORC-Compliant Resource Estimate
With the infill drilling phase complete, Iltani has engaged independent mining consultants Mining One to model the data and estimate an initial JORC Resource for Orient West, targeting completion by the end of July 2025. The company also recently finished drilling at Orient East, with assay results pending and a resource estimate expected by September 2025. These milestones are critical steps in advancing the project from exploration towards development.
Strategic Exploration and Future Drilling Plans
Complementing the drilling, Iltani has received final data from a VTEM geophysical survey, with modelling underway by Mitre Geophysics. This work aims to identify additional high-priority targets within the Orient area. The company plans to recommence drilling on these geophysical anomalies towards the end of July, seeking to expand the resource base and enhance grade and tonnage potential.
Implications for Mining and Market Positioning
The high-grade silver-indium intercepts and continuity of mineralisation at Orient West position Iltani as a significant player in Australia’s silver-indium sector. The potential for both open pit and underground mining operations adds flexibility to future development scenarios. As the company moves towards formal resource declarations, market participants will be watching closely for how these results translate into economic value and project viability.
Bottom Line?
Iltani’s imminent JORC Resource estimates will be pivotal in defining the commercial trajectory of its promising silver-indium assets.
Questions in the middle?
- What will the initial JORC Resource estimate reveal about the scale and grade of Orient West?
- How might metallurgical recoveries and payable metals assumptions evolve with further test work?
- What impact will upcoming drilling on VTEM targets have on the overall resource potential?
