Iltani Resources has recently restarted its comprehensive drilling campaign at the Orient Silver-Indium Deposit in Queensland, capitalising on a surge in silver prices that have reached US$34/oz (A$53/oz). The renewed focus on exploration comes at a time when the mining sector is witnessing renewed investor interest due to favourable commodity markets and the growing significance of critical minerals such as indium.
Silver Price Surge and Drilling Campaign
The recent uptick in silver prices has not only provided a timely window of opportunity for Iltani but also underscored the strategic importance of continued exploration in a competitive market. The company has embarked on a robust drilling programme that is set to make significant strides in uncovering new insights into what is described as Australia's largest known deposit of silver-indium. This ambitious campaign includes:
- A track-mounted RC drill rig operating at Orient West with 28 drill holes planned.
- A wheel-mounted RC drill rig scheduled to be deployed at Orient East by the end of the month with 26 drill holes planned.
- An upcoming diamond drilling phase set to commence in late April, targeting 4 holes.
Managing Director Donald Garner expressed his optimism about the timing of the campaign, stating, "What a great time to get our drilling underway and move forward our exploration at Orient. We are hopeful the drilling picks up where we paused at Orient West at the end of 2024, producing results that delivered high-grade mineralisation." This statement reflects not only the excitement within the company but also a clear strategy to leverage market conditions in order to deliver compelling results.
Strategic Drilling for a World-Class Resource
The primary objective of the drilling programme is to convert existing Exploration Targets into JORC-compliant Inferred Mineral Resources. By focusing on both the Orient West and Orient East deposits, Iltani is effectively setting the stage for a future where high-grade, polymetallic resources are systematically defined and developed. The details of these targets are both ambitious and promising:
Orient West:
- Exploration Target: 20-24 million tonnes grading 110-120 g/t silver equivalent.
- Drilling Programme: 28 RC holes totalling approximately 7,000 metres, complemented by 2 diamond holes totalling around 450 metres.
- Historical Success: Previous drilling in late 2024 reported intercepts as high as 1,933 g/t Ag Eq, highlighting the potential for extraordinary mineralisation.
Orient East:
- Exploration Target: 12-18 million tonnes grading 110-130 g/t silver equivalent.
- Drilling Programme: Involves 26 RC holes covering roughly 5,200 metres, along with an additional 2 diamond holes totalling 450 metres.
- Timeline: The drilling is set to commence by the end of March, an indication of Iltani's commitment to exploring all feasible avenues within the deposit.
In addition to these drilling efforts, independent mining consultant Mining One is tasked with modelling and estimating the initial JORC Resources, ensuring that the data is rigorously evaluated and meets industry standards.
What is Silver Equivalency and Why Does It Matter?
A key element in presenting the value of the Orient deposit is the concept of silver equivalency (Ag Eq.). This metric is crucial in understanding the combined economic worth of the multiple valuable metals hosted in the deposit. By expressing the value of metals such as silver, lead, zinc, and indium in equivalent silver terms, the company provides a clear picture of the overall potential of the resource.
The formula used by Iltani is as follows:
Ag Eq. = Ag + (Pb × 35.5) + (Zn × 50.2) + (In × 0.47)
This calculation assumes recoveries of:
- 87% for silver,
- 90% for lead,
- 85% for zinc, and
- 85% for indium.
Using such a formula, the company is able to incorporate the individual contributions and recovery rates of each metal, ensuring that the combined resource is assessed in a manner that truly reflects its economic potential.
Understanding the Role of Indium
Indium, a semi-precious metal with a unique suite of properties, assumes a particularly significant role in the Orient deposit. Not only is indium a critical component in various high-tech applications, but its presence also adds substantial value beyond what is typically associated with silver alone. Characteristics of indium include:
- Its utilisation in indium tin oxide (ITO), which is indispensable in the production of flat-panel displays, touchscreens, and LCD screens.
- Its role in the electronics sector, where it is incorporated into semiconductors, solders, and various electrical components.
- Its importance in solar technology, specifically in the production of copper-indium-gallium-selenide (CIGS) thin-film solar cells.
- A supply chain that is predominantly reliant on recovery as a by-product of zinc, with global production significantly influenced by China's control.
These attributes underscore the strategic advantage of having a critical mineral like indium integrated within a broader silver deposit. Investors and industry experts recognise that such dual exposure not only hedges against market volatility in any one commodity but also positions the company favourably in a market that is increasingly focused on technology and sustainability.
Exploring Beyond the Known Boundaries
Even as the current drilling campaign focuses on the key targets at Orient West and East, Iltani has not lost sight of the broader potential within the 6km² Orient system. The company has identified several additional areas that may harbour further mineralisation:
- Orient North – a high-priority target bolstered by evidence of historical workings and geophysical anomalies.
- Orient South – another target of significant interest.
- Orient Undercover – an area located between Orient West and East that has already revealed promising intercepts through previous drilling programmes.
These targets serve as a reminder that the known deposits may just be the tip of the iceberg. The presence of multiple prospective zones within a single system opens up exciting avenues for future exploration, which in turn could potentially lead to an even larger and more complex resource.
A Compelling Investment Thesis
When evaluating the prospect of Iltani Resources, several key factors emerge that make the company an attractive investment:
-
Resource Scale Potential:
- Combined high-grade core of the Orient Exploration Target stands at 32-42 million tonnes at 110-124 g/t Ag Eq.
- Represents a substantial polymetallic resource poised for future growth.
-
Timing Advantage:
- Silver currently trading at multi-year highs provides an opportune moment for both exploration and future resource development.
- The market conditions are highly favourable for progressing a flagship project such as Orient.
