Iltani Resources Delivers Exceptional High-Grade Silver-Indium Discoveries at Orient

Iltani Resources Limited (ASX: ILT) has delivered exceptional drilling results from its Orient Silver-Indium Project in North Queensland, with diamond drilling confirming extensive high-grade mineralisation zones and positioning the company for advanced metallurgical testing. The high-grade discoveries by Iltani Resources validate the company's systematic exploration approach whilst preparing for production optimisation studies.

Outstanding Drilling Results Validate Orient Project Potential

The recently completed diamond drilling programme at Orient has delivered remarkable intersections that confirm the project's substantial mineral potential. ORD007 at Orient East intersected 27m at 225.2 g/t silver equivalent from 77m, including an exceptional 1.5m at 2,414.5 g/t silver equivalent containing 578.0 g/t silver, 349.9 g/t indium, 14.34% lead, and 22.74% zinc.

Similarly impressive, ORD006 at Orient West intersected 35m at 98.1 g/t silver equivalent from 80m, featuring multiple high-grade zones including 4.2m at 278.5 g/t silver equivalent and 0.4m at 1,126.2 g/t silver equivalent. Furthermore, these results demonstrate the consistency of mineralisation across both eastern and western zones.

Key Drilling Results Comparison

Managing Director Donald Garner: "The diamond drill holes were designed to twin existing RC holes… It is good to see that the intersections in both ORD006 and ORD007 closely match the intersections in the RC holes. This gives us a strong level of confidence in the RC drilling, which is good, as we are planning to do a lot more RC drilling at Orient in 2026."

Understanding Silver Equivalents: The Value Multiplier

Silver equivalent (Ag Eq.) represents the combined value of all recoverable metals expressed as an equivalent amount of silver. This critical metric allows investors to understand the true economic potential of polymetallic deposits like Orient.

Iltani's silver equivalent calculation incorporates:

• Silver recovery: 87% at US$20/oz
• Lead recovery: 90% at US$1.00/lb
• Zinc recovery: 85% at US$1.50/lb
• Indium recovery: 85% at US$350/kg

The formula: Ag Eq. = Ag + (Pb x 35.5) + (Zn x 50.2) + (In x 0.47)

This approach provides investors with a single comparable metric whilst accounting for the economic contribution of each metal component, crucial for evaluating the project's commercial viability. In addition, these high-grade discoveries by Iltani Resources further enhance the economic attractiveness of the Orient Project.

Metallurgical Testing Programme Advances Toward Production

The drilling programme successfully generated 240kg of representative bulk samples (120kg each from Orient East and West) for comprehensive metallurgical testing at Core Resources in Brisbane. This strategic initiative represents a significant step toward production optimisation, with results expected by mid-2026.

The systematic approach to metallurgical testing demonstrates Iltani's commitment to de-risking the project whilst optimising recovery processes. Historical test work has already confirmed the potential to recover silver, indium, lead, and zinc into saleable concentrates, providing a foundation for the current programme.

However, the real value lies in how these results will guide future processing strategies. For instance, the exceptional grades encountered in recent drilling provide confidence in the deposit's commercial viability.

Drilling Validation Results

Australia's Largest Silver-Indium Resource Grows Stronger

Orient represents Australia's largest known silver-indium deposit, strategically located 120km southwest of Cairns in the historically productive Herberton Mineral Field. The project benefits from established infrastructure and a rich mining heritage spanning over 140 years.

The significance of these high-grade discoveries by Iltani Resources cannot be overstated when considering the project's scale and location advantages. Furthermore, the deposit's proximity to existing infrastructure reduces potential development costs significantly.

Current Resource Position

Exploration Target: Additional 15.4-18.8 Mt @ 95-117 g/t Ag Eq. presents significant expansion potential, with conversion drilling planned for 2026. Consequently, this represents substantial upside potential for investors.

Strategic Investment Thesis: Critical Metals in a Tier-1 Location

The Orient Project positions Iltani at the intersection of several powerful investment themes that make it an attractive proposition for sophisticated investors.

Critical Metals Exposure: Indium's essential role in renewable energy technology, combined with silver's industrial and monetary demand, creates a compelling dual-commodity exposure. Moreover, both metals benefit from structural supply-demand imbalances.

Scale and Grade Combination: The 34.2 Mt resource at 110.4 g/t silver equivalent represents exceptional scale in Australia's silver sector, whilst recent drilling continues to identify higher-grade zones. The high-grade discoveries by Iltani Resources further reinforce this advantage.

Infrastructure Advantage: Located within established mining infrastructure in North Queensland, the project benefits from accessible power, transport, and skilled labour resources. In addition, regulatory certainty in Australia provides additional investor confidence.

Systematic De-risking: The methodical approach to metallurgical testing and resource expansion demonstrates management's commitment to value creation through systematic project advancement.

Why Investors Should Monitor Iltani Resources

The combination of exceptional recent drilling results, systematic project advancement, and strategic positioning in critical metals makes Iltani increasingly compelling. Queensland Investment Corporation's recent $8.0M investment validates the project's commercial potential whilst providing funding for accelerated development.

With extensive RC drilling planned for 2026 and metallurgical results expected mid-year, multiple value catalysts are approaching. The successful twinning of diamond and RC drilling provides confidence in the expanded drilling campaign, whilst the substantial exploration target offers significant resource growth potential.

However, investors should note that the mining sector carries inherent risks, including commodity price volatility and operational challenges. For instance, metallurgical testing results could impact project economics, though historical work suggests positive outcomes.

Investment Tracking Points

Key Takeaway: Iltani Resources has positioned itself as Australia's leading silver-indium developer, with recent exceptional drilling results validating the Orient Project's world-class potential. With multiple catalysts approaching in 2026 and strong backing from Queensland Investment Corporation, investors should closely monitor this emerging critical metals story.
