Infinity Metals Clears Final Hurdle to Drill Undrilled Tin Target Next Month
Key Takeaways
- Infinity Metals has received its drilling approval from the Department NSW Resources and secured landholder access, so Yambacoona aircore drilling can start in late October.
- Up to 35 aircore holes will test a geophysical target under 15-20m of transported cover that has never been drilled.
- Wallis Drilling is engaged for a low-cost reconnaissance programme on the 100%-owned project in EL9796, about 60km east of Bourke.
- The company says tin is sustaining about US$55,000/t, but no resource or mineralisation has been defined at Yambacoona.
- No assay timing, budget or results dates were disclosed, and Infinity says its main focus remains U.S. copper-molybdenum assets.
Yambacoona Tin Project drilling approved, with aircore programme to start in late October
Infinity Metals (ASX:INF) has received approval of its drilling application, known as an Assessable Prospecting Operation (APO), from the Department NSW Resources for the Yambacoona Tin Project. The announcement is dated 6 October 2026.
Approval of the proposed works was the last stage, in conjunction with securing land access with all stakeholders. The company has engaged Wallis Drilling to execute the programme, with a start in late October.
The planned programme is a low-cost reconnaissance drilling campaign on the company’s 100% owned Yambacoona Project. It will consist of up to 35 aircore (AC) drillholes testing a geophysical target within EL9796.
With approvals and access in place, the project moves from planning to execution. That is a practical step for investors watching how quickly the company turns plans into field work.

What is the drilling testing near known tin mineralisation?
What the drilling will test
The target was identified by a geophysical survey and has never been drilled. Bedrock is estimated to sit 15-20m below transported cover, which is sediment that has been moved in and now covers the rock beneath.
The programme is looking for a repeat of tin deposit along strike. It is also designed to test for broad zones of alteration, which would support the skarn-type mineralisation model hypothesised by Infinity.
Prior drilling is limited. There have been only two documented historical drill holes, drilled by Rio Tinto in the 1990s in the very northern portion of the tenement, and these tested a separate target to the geophysical anomalies Infinity will drill.
Location and geological comparison
The project is located approximately 60km east of Bourke, New South Wales. The company describes it as prospective for tin-lithium and rare earth minerals, sharing significant geological similarities with the proximal Doradilla project held by Sky Metals (ASX:SKY).
The drilling is a preliminary reconnaissance over an area under transported cover, so no resource or mineralisation has been defined at Yambacoona. For context, the tenement was granted on 12 February 2026, and the earlier announcement titled “Yambacoona Tin Project” holds more detailed project information.
| Fact | Investor impact |
|---|---|
| Never-drilled target | First test of the geophysical anomaly |
| Aircore, low-cost | Limited capital outlay |
| Near Doradilla-style geology | Exploration analogue only |
What does the tin market backdrop mean for explorers?
Tin pricing at record levels
The company says the tin market has consolidated around record pricing levels, with consistent demand increases and supply that has not responded. Tin prices are now sustaining approximately US$55,000/t, according to the announcement.
Strong pricing improves the appeal of any tin discovery, though Yambacoona remains at the earliest stage of testing.
Why aircore drilling suits early-stage targets
Aircore drilling is a fast, low-cost method that samples shallow rock through cover. Explorers often use it to screen targets before committing to costlier drilling.
That matters here because it lets Infinity test an undrilled target without a large capital outlay.

Does Infinity still focus on U.S. copper-molybdenum assets?
Yes. The company states that its focus remains on copper-molybdenum assets in the U.S.A, and it describes Yambacoona as a low-cost reconnaissance programme.
The announcement does not disclose assay timing, budgets or results dates. The next step is the start of drilling in late October.
