Austin Metals Hits 12m at 1.67g/t Gold Opening Up 3km Unexplored BIF Trend
Key Takeaways
- Brunswick Hill's standout hole — 12m at 1.67 g/t Au including a 1m peak of 12.70 g/t Au — validates the structural targeting model and defines a specific high-grade shoot for follow-up drilling.
- New pXRF and micro-XRF data have fundamentally revised the Mt Sandy geological model, identifying untested cross-cutting lode structures as the priority targets for the next drill phase.
- Approximately 3km of largely underexplored BIF stratigraphy at Brunswick Hill is now framed by a confirmed structural model, converting open ground into a ranked list of testable fault intersection targets.
- A UAV high-resolution magnetic survey commencing October 2026 is the next near-term catalyst, designed to refine fault and contact geometry ahead of follow-up RC drilling at both prospects.
- Austin Metals holds a 111 km² tenement position adjacent to Ramelius Resources' Cue Gold Project and bordering Caprice Resources' Island Gold Project, with no Mineral Resource yet defined — this remains early-stage exploration.
Drilling sharpens the picture at Austin Gold Project
Austin Metals (ASX: AYT) has reported assay results from a 21-hole, 4,215m reverse circulation (RC) drilling programme at its Austin Gold Project in the Murchison region of Western Australia. The programme, which commenced in June 2026, has advanced geological understanding across two prospects — Mt Sandy and Brunswick Hill — and refined targets for the next phase of drilling.

Mt Sandy and Brunswick Hill results at a glance
The programme returned encouraging intercepts at both prospects. Key highlights are summarised below.
Mt Sandy:
- 4m @ 1.07 g/t Au from 32m (26MSRC008), including 2m @ 1.86 g/t Au and a peak 1m @ 3.03 g/t Au from 34m
- 2m @ 1.61 g/t Au from 32m (26MSRC003)
- Mineralisation traced along an interpreted trend of approximately 2km, open at depth
Brunswick Hill:
- 12m @ 1.67 g/t Au from 21m, including 7m @ 2.70 g/t Au and a peak 1m @ 12.70 g/t Au from 26m (26BHRC006)
- 4m @ 0.56 g/t Au from 48m and 1m @ 1.04 g/t Au from 110m (26BHRC001)
- Approximately 3km of prospective Banded Iron Formation (BIF) stratigraphy remains largely underexplored
Managing Director Michael Moore
“We are extremely encouraged by what this drilling program has delivered. Importantly, it has done much more than return gold intersections, it has significantly advanced our understanding of geology, the controls on mineralisation and where we should be focusing our next efforts…
…The similarities with the geological setting at Break of Day provide a useful conceptual model and give us a much clearer understanding of what we should be targeting next…
…the promising intersection of 12m at 1.67 g/t gold, including 1m at 12.70 g/t gold, demonstrates system’s potential to generate high-grade gold.”

What the geology is telling Austin Metals
The programme delivered more than assay numbers. New multi-element and mineralogical data have prompted revised geological models at both prospects, pointing to structurally controlled, higher-grade targets that have not yet been drilled.
Mt Sandy — a revised model with higher-grade potential
The previous interpretation at Mt Sandy held that gold mineralisation was associated with a sheared contact zone between basalt and intermediate rocks. New data, including portable X-ray fluorescence (pXRF) multi-element readings and micro-XRF mineralogy analysis conducted by Portable Spectral Services using a Bruker M4 TORNADO PLUS instrument, now points to a differentiated high-titanium dolerite sill as the host rock.
In plain terms: gold appears to concentrate where the mineralised contact of this dolerite sill intersects cross-cutting structures rather than sitting uniformly along the contact itself. Those structural intersection points represent higher-grade targets that the current drilling has not yet tested.
The company notes a conceptual similarity with Ramelius Resources’ (ASX: RMS) Break of Day deposit, located approximately 9.7km west-southwest of Mt Sandy, where gold in brittle quartz lodes is associated with high-titanium basalt. The company is explicit that this is a conceptual model only and does not imply equivalent grade, geometry, scale or continuity.
Austin Metals’ approach to drilling near top producers in the Murchison region has shaped its targeting logic from the outset, with the proximity to Ramelius Resources and Caprice Resources informing both prospect selection and the geological analogues the company uses to frame its models.
Brunswick Hill — structural intersections, not simple BIF continuity
BIF (Banded Iron Formation) is a layered sedimentary rock type that can host gold mineralisation where structural disruption has allowed hydrothermal fluids to deposit gold. The key insight from the Brunswick Hill drilling is that gold is not distributed evenly along the BIF corridor — it is concentrated at points where northeast- and northwest-trending faults cut through the BIF.
This is described as a “Vadrians-style” targeting model, a reference to structural similarities observed from public data interpreted to have a control on Caprice Resources Limited’s Vadrians Deposit, adjacent to Austin’s project boundary. The company is clear this is an analogy, not a claim of equivalence. The significance of the current results is that they validate this structural model: discrete, higher-grade gold-bearing shoots exist within structurally disrupted BIF, and the 3km of largely underexplored BIF stratigraphy now provides a clear framework for follow-up targeting.

What comes next for the Austin Gold Project
The 2026 programme has generated specific, testable targets at both prospects. The company has outlined a sequenced pipeline of activity ahead of the next drill phase.
- Data integration — pXRF, magnetic susceptibility and structural mapping to rank follow-up drilling targets
- Geochemistry — petrography, whole-rock analysis and laboratory multi-element geochemistry
- UAV high-resolution magnetic survey — commencing October 2026, to refine geological contacts, faults and auriferous structures
- Follow-up RC drilling — priority targets to be ranked, with focus on cross-cutting lode structures at Mt Sandy, the lateral extent of high-grade mineralisation in 26BHRC006, and further BIF targets south along the Brunswick Hill trend
Why this matters for investors
Austin Metals holds a 111 km² tenement position in the Murchison greenstone province, adjacent to Ramelius Resources’ Cue Gold Project and bordering Caprice Resources’ Island Gold Project (including the Vadrians gold system). Two distinct gold systems are being refined simultaneously on this ground.
Each drilling phase is systematically narrowing targets. The next phase is expected to test the higher-grade potential at Mt Sandy’s structural intersections — the cross-cutting lode structures that the revised geological model now identifies as the key priority — and the lateral extent of the 12.70 g/t Au peak hit at Brunswick Hill.
Investors should note that this is early-stage exploration. No Mineral Resource or Ore Reserve has been defined, and the drill spacings achieved to date are sufficient for geological interpretation but not for resource classification.
For investors tracking how the target list has developed across successive programmes, our detailed coverage of Austin Metals’ evolving target pipeline explains how earlier geophysical work and historical data shaped the priority ranking that the 2026 programme was designed to test.
