Iltani Resources Transforms Orient into Australia’s Largest Silver-Indium Deposit

FLAGSHIP PROJECT EMERGING AS A SIGNIFICANT CRITICAL MINERALS DEPOSIT

Iltani Resources silver-indium project has transformed the Orient Silver-Indium Project from an underexplored prospect to Australia's largest known silver-indium deposit in just 24 months since its June 2023 IPO. The company has completed an impressive 118 reverse circulation drill holes and 5 diamond drill holes at Orient during this period.

Recent drilling results continue to expand the scale of this massive mineralised system, which spans over 6km² with multiple stacked vein structures.

The global exploration target for Orient currently stands at an impressive 32-42 million tonnes at 110-124 g/t silver equivalent (using an 80 g/t Ag Eq. cut-off grade), containing:

• 30-37 g/t silver
• 15-18 g/t indium
• 0.7-0.9% lead
• 0.9-1.1% zinc

ORIENT EAST DRILLING DELIVERS EXCEPTIONAL RESULTS

Recent drilling at Orient East has delivered excellent high-grade intercepts, including:

• 24m @ 148.4 g/t Ag Eq. from 90m including:
  • 5m @ 374.1 g/t Ag Eq. from 104m
  • 3m @ 494.5 g/t Ag Eq. from 106m downhole

The mineralisation at Orient East remains open to the south and west, with additional drilling planned to target these extensions.

ORIENT WEST DIAMOND DRILLING CONFIRMS HIGH-GRADE CORE

Diamond drilling at Orient West has intersected impressive high-grade silver mineralisation, including:

• 5m @ 428.6 g/t Ag Eq. from 56m including:
  • 2.8m @ 737.3 g/t Ag Eq. from 57m
  • 0.83m @ 1,838.4 g/t Ag Eq. from 58.4m

WHAT IS INDIUM AND WHY IT MATTERS

Indium is a critical mineral essential for modern technology and the clean energy transition. This rare metal has become increasingly important in the global supply chain due to its unique properties and limited production sources.

Key Applications of Indium

1. Indium Tin Oxide (ITO): Forms a transparent conducting coating used extensively in touchscreens, LCD displays, and solar panels. ITO allows light to pass through while conducting electricity, making it essential for modern displays.

2. Semiconductor compounds: Indium is used to create indium phosphide, indium arsenide, and indium antimonide semiconductors for high-performance electronics, including high-speed transistors and photonic devices.

3. Low-temperature solders: Indium's low melting point and excellent wetting properties make it valuable for specialised electronics manufacturing, particularly where temperature-sensitive components are involved.

4. Medical applications: Used in radiation detection equipment and nuclear medicine due to its unique physical properties.

Strategic Importance

Indium's classification as a critical mineral by major economies including the US, EU, and Australia reflects its essential role in technology manufacturing and concerns about supply security. Global production is limited, with China accounting for approximately 60% of refined indium production.

As demand for touchscreens, displays, and solar panels continues to grow, securing reliable sources of indium has become a strategic priority for many countries seeking to reduce dependency on dominant suppliers.

"Orient represents a significant discovery for Australia's critical minerals sector. The presence of substantial indium alongside silver provides important diversification beyond traditional precious and base metals," notes Donald Garner, Managing Director of Iltani Resources.

METALLURGICAL TESTING CONFIRMS COMMERCIAL POTENTIAL

Metallurgical testing has confirmed that silver, indium, lead, and zinc can be recovered and are payable in concentrate form:

• Silver and lead will be recovered to a lead-silver concentrate
• Zinc, silver, and indium will be recovered to a zinc-indium-silver concentrate

The company notes that tin and antimony are also present and likely recoverable, though they're currently excluded from metal equivalent calculations as they're not assumed to be payable at this stage.

Metal Equivalent Calculation

The silver equivalent (Ag Eq.) formula used by Iltani is:
Ag Eq. = Ag + (Pb x 35.5) + (Zn x 50.2) + (In x 0.47)

This calculation incorporates:

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

2025 DEVELOPMENT PATHWAY

Iltani has outlined a clear path forward for the Orient project:

• Orient West JORC Resource: Expected by end of July 2025
• Orient East JORC Resource: Expected by September 2025
• Exploration expansion: Following completion of an airborne geophysical survey
• Discovery upside: Targeting gold projects, particularly Boonmoo Epithermal Gold
• Follow-up on VTEM targets: In the highly prospective Boonmoo Sag Caldera

Systematic Exploration Approach

The company's exploration methodology has been methodical and effective. Mineralised intercepts in downhole drilling align from section to section along structures that can be assumed to be continuous between drillholes. This systematic approach has allowed Iltani to build a comprehensive understanding of the Orient deposit's geometry and grade distribution.

The exploration model integrates drilling data with soil anomalism above the mineralised veins and the extent of historic workings which have been rock chip sampled. This multi-faceted approach provides greater confidence in the continuity and extent of the mineralisation.

INVESTMENT OPPORTUNITY

With a market capitalisation of just $13.5 million and an enterprise value of $11.5 million (as of July 21, 2025), Iltani presents an opportunity to invest in a rapidly advancing critical minerals project with significant scale potential.

The company had $2.0 million cash as of March 31, 2025, and has delivered consistent exploration success since its IPO. With resource estimates imminent and the deposit continuing to grow, Iltani Resources silver-indium project is positioning itself as a significant player in the silver and critical minerals space.

Corporate Overview

WHY INVESTORS SHOULD FOLLOW ILTANI RESOURCES

1. Australia's largest silver-indium deposit – still growing with open mineralisation in multiple directions
2. Critical minerals exposure – indium is essential for technology and clean energy applications
3. Near-term catalysts – JORC Resources for both Orient West and East expected in Q3 2025
4. Experienced management – delivering consistent exploration success since IPO
5. Substantial exploration upside – with multiple targets still to be tested across a 367km² tenement package in the historic Herberton Mineral Field

As the first company to conduct modern exploration at Orient since the 1980s, Iltani has the first-mover advantage in what appears to be an emerging mineral district with substantial critical minerals potential.

The company's broader portfolio includes additional exploration permits across Northern Queensland and Tasmania, providing further upside potential beyond the flagship Orient project.
