Austin Metals (ASX:AYT) reported progress on its BIF-hosted gold targeting at the Brunswick Hill prospect, part of its Austin Gold Project in the Murchison Goldfields of Western Australia.
The company's updated model highlights a Vadrians-style gold system supported by recent shallow, high-grade drilling, including 2m at 10.3 g/t Au from 62m (24BHRC04) and 6m at 3.5 g/t Au from 65m, including 1 m at 17.1 g/t Au (24BHRC05).
Brunswick Hill’s BIF corridor remains largely underexplored, with over 2km of prospective strike identified but only around 500m partially tested.
The mineralisation is interpreted to occur within oxide-facies jaspilite and magnetite–chert BIF, particularly where these competent horizons are folded, fractured, or cross-cut by brittle faults, with gold associated with sulphides and quartz veining.
Structural controls, including faults and fold hinges, are considered key pathways for high-grade mineralisation, consistent with successful nearby discoveries at Comet, Tuckabianna, and The Island.
Austin Metals plans early 2026 geophysical interpretation and field validation to refine drill targets along the largely untested Eastern Contact Zone and other high-priority BIF corridors, aiming to convert its refined model into systematic drilling and potential new discoveries.
