Iron Road Commences Stage 2 Drilling at TAU-A Nickel-Copper-Gold Target
Key Takeaways
- Iron Road has commenced Stage 2 reverse circulation drilling at the TAU-A target within the Irria Prospect at the Mulgathing Project in South Australia, shifting the program from planning to active field work.
- The initial program consists of two RC holes to approximately 150 metres depth, with a contingency for up to four additional holes triggered by on-site RC chip observations and portable XRF results.
- Drilling is being conducted under a farm-in and JV agreement with Red Tiger Resources Ltd over EL6580, a structure that distributes exploration risk between the two parties.
- TAU-A targets nickel, copper, and gold — three commodities with distinct demand profiles — and the next material event for investors is the release of drill results from the initial two holes.
- Portable XRF analysis will allow geologists to make real-time field decisions on whether to trigger the contingency holes, meaning the program scope could expand quickly without waiting for laboratory turnaround.
Stage 2 drilling gets underway at the TAU-A nickel-copper-gold target
Iron Road Ltd (ASX: IRD) has commenced Stage 2 reverse circulation (RC) drilling at the TAU-A target, located at the Irria Prospect within the Mulgathing Project in South Australia. The program is being conducted under a farm-in and JV agreement with unlisted public company Red Tiger Resources Ltd over EL6580, an arrangement first disclosed in the 26 June 2025 ASX announcement.
Drilling is live. The company released a comprehensive update on the TAU-A target on 4 March 2026, and field activity is now progressing as planned.

What is RC drilling and why does it matter for explorers?
Reverse circulation (RC) drilling is a method that uses a dual-wall drill rod to force compressed air through the drill bit and return rock chips to the surface through the inner tube. Unlike traditional open-hole methods, RC drilling produces dry, uncontaminated chips that are representative of the rock at depth, making them far more reliable for geochemical analysis.
Those chips are then tested in the field using a portable X-ray fluorescence (XRF) analyser, a handheld device that measures elemental composition in near real-time. For explorers, this is a critical tool. It means geologists can review preliminary geochemical results hole-by-hole, without waiting for laboratory turnaround, and make field decisions on whether to drill more holes or stop.
That is precisely why Iron Road’s contingency structure matters. The initial two holes are the primary test, but if RC chip observations and portable XRF results indicate something worth chasing, up to four additional holes can be drilled immediately. Commencement of drilling is the moment this feedback loop begins.
TAU-A target profile and program structure
TAU-A is a nickel-copper-gold exploration target within the Irria Prospect at the Mulgathing Project. The program has been designed with a clear decision-making process built in: two initial holes establish the primary test, and field results determine whether the program expands.
The structure of the current drill program is as follows:
- Target commodities: Nickel, copper, gold
- Location: Irria Prospect, Mulgathing Project, South Australia
- Tenure: EL6580, under a farm-in and JV agreement with Red Tiger Resources Ltd
- Initial drill holes: 2 x approximately 150m RC holes
- Contingency: Up to 4 additional holes to similar depth, subject to RC chip observations and portable XRF results
- Prior target update: ASX Announcement, 4 March 2026
No drill results, intercept data, or grade information have been disclosed at this stage of the program.

What comes next for Iron Road investors
The near-term catalyst is the drill results themselves. The initial two holes are expected to be sufficient to test the TAU-A target, but field observations and portable XRF data will determine whether the contingency holes are triggered, potentially extending the program to six holes in total.
Iron Road has confirmed it will keep the market informed of progress. At this point, drilling is underway and results are the next material event.
The broader context is worth keeping in mind. Iron Road is exploring a nickel-copper-gold system through a JV structure with Red Tiger Resources Ltd, an arrangement that distributes exploration risk. For investors watching the stock, the commencement of drilling shifts the conversation from planning to results. That is a meaningful change in status for a junior explorer.
