Iltani Resources Accelerates Silver-Indium Discovery with New Drilling Campaign
Iltani Resources (ASX: ILT) has commenced an extension drilling program at Orient East, part of Australia's largest known silver-indium deposit. The nine-hole reverse circulation (RC) drilling campaign targets significant mineralisation extensions that could substantially increase the company's resource base.
Drilling Campaign Aims to Expand Australia's Premier Silver-Indium Resource
Iltani has initiated drilling at Orient East with hole ORR119, the first in a nine-hole RC program designed to test extensions to known mineralisation. The program, expected to complete in early September, will target an area southwest of Orient East where previous drilling indicated the mineralisation remains open.
"It is good to be back drilling at Orient East," said Managing Director Donald Garner. "The drilling is designed to test an area to the SW of Orient East, where the mineralisation previously intersected in drilling remains open."
While the drilling will delay the Orient East Mineral Resource Estimate (MRE) to late September/early October, management believes the potential resource addition justifies the postponement.
The campaign follows exceptional results from previous drilling that included:
- 24m at 148.5 g/t Ag Eq. from 90m (ORR105)
- 32m at 161.0 g/t Ag Eq. from 115m (ORR109)
- 8m at 190.7 g/t Ag Eq. from 104m (ORR114)
Orient: Australia's Largest Silver-Indium Discovery
The Orient project represents Australia's largest silver-indium discovery and is divided into two main areas:
| Area | Resource Classification | Tonnage | Grade | Contained Silver Equivalent |
|---|---|---|---|---|
| Orient West | JORC Resource | 21.6Mt | 100.5 g/t Ag Eq. | 69.9 Moz Ag Eq. |
| Orient East | Exploration Target | 12-18Mt | 110-130 g/t Ag Eq. | Pending MRE |
The Orient West resource already contains 18.7 million ounces of silver, 456,000 tonnes of indium, 128,000 tonnes of lead, and 184,000 tonnes of zinc.
With the current drilling program, Iltani aims to convert the Orient East Exploration Target into a JORC-compliant resource, potentially adding significant tonnage to the company's overall resource base.
Understanding Indium: A Critical Metal for Modern Technology
Indium is a strategic metal rarely found in dedicated mining operations but typically recovered as a by-product of zinc processing. This silvery-white metal has become increasingly important due to its unique properties:
- Essential component in touchscreens and LCD displays
- Used in high-efficiency solar panels
- Critical for semiconductor manufacturing and electronics
- Applications in aerospace and specialised alloys
Indium's growing importance in renewable energy and technology makes it a valuable component of Iltani's Orient deposit. The company's metallurgical testing has confirmed the potential to recover indium alongside silver, lead, and zinc in commercial concentrates.
"The drilling has the potential to materially increase the MRE, so we decided it was well worth completing," noted Managing Director Donald Garner, highlighting the strategic importance of the current program.
Herberton Project: A Strategic Metals Portfolio
The Orient deposit forms part of Iltani's larger Herberton Project, which encompasses approximately 367km² of wholly owned tenements in northern Queensland's Herberton Mineral Field. This historically productive region has seen mining activity since 1880, with more than 2,400 historic mines and prospects known throughout the area.
The project area covers the Boonmoo Sag Caldera, which hosts:
- The Orient silver-indium system
- Several historic copper, silver-lead-zinc mines
- Multiple gold targets
- The high-grade Isabel deposit (copper-lead-zinc-indium-silver)
Iltani's field crews have been actively assessing numerous VTEM (Versatile Time Domain Electromagnetic) targets identified by the company's geophysical consultants, while also sampling regional prospects throughout the central area of the Boonmoo Sag Caldera.
Investment Thesis: Positioned for Growth in Critical Metals
Iltani Resources represents a compelling investment opportunity in the critical and precious metals space for several key reasons:
-
Australia's largest silver-indium resource: The Orient deposit provides exposure to both precious metals and critical technology metals in a single project.
-
Resource growth potential: The current drilling program aims to substantially increase the overall resource base at Orient East.
-
Strong metallurgical results: Previous test work has confirmed the potential to produce commercial concentrates containing silver, lead, zinc, and indium.
-
Strategic mineral portfolio: The company's focus on metals required for the low-emission future aligns with growing global demand trends.
-
Experienced management: The team has demonstrated the ability to advance the project methodically with consistent exploration success.
The company's equivalent silver formula (Ag Eq. = Ag + (Pb x 35.5) + (Zn x 50.2) + (In x 0.47)) reflects the potential value of the multi-metal resource, with metallurgical testing supporting the recovery assumptions for all included metals.
Why Investors Should Follow Iltani Resources
Iltani represents a unique opportunity to gain exposure to both precious and critical metals within a single investment. As the company advances toward completing its Orient East resource estimate in the coming months, several catalysts could drive significant value:
- Resource expansion: The current drilling program could substantially increase the overall resource base.
- Resource classification upgrade: Converting the Orient East Exploration Target to a JORC-compliant resource represents a major milestone.
- Further exploration success: The company continues to assess regional targets within its extensive tenement package.
- Advancing toward development: As resources grow, the pathway toward potential production becomes clearer.
With silver continuing to play its dual role as both precious metal and industrial commodity, and indium's growing importance in technology applications, Iltani's Orient project addresses multiple market demands. The company's focus on defining and expanding Australia's largest silver-indium resource positions it strategically in the evolving metals landscape.
Key Takeaway:
Iltani Resources has positioned itself as a significant player in the silver and critical metals sector, with substantial upside potential through its ongoing Orient East drilling program. With results expected by early September and a resource estimate to follow shortly after, investors should keep a close eye on developments that could substantially expand Australia's largest silver-indium resource.
