Austin Metals Sharpens Drill Targets with New Geophysical and Sampling Data

Refined Structural Framework Boosts Exploration Focus

Austin Metals Limited (ASX:AYT) is tightening its grip on the geology of its Austin Gold Project in Western Australia’s Murchison region, leveraging a sophisticated blend of reprocessed aeromagnetic data, drone surveys, and targeted rock-chip sampling. The company’s updated litho-structural interpretation, led by Dr Robin Armit of PGN Geoscience, has delineated multiple banded iron formation (BIF) horizons and significant shear zones that are interpreted as key controls on gold mineralisation.

This enhanced structural framework, supported by advanced filtering techniques on 2020 aeromagnetic data, is sharpening drill targeting at the Northern Zone prospects of Brunswick Hill, Mt Sandy, and Golconda Well. The approach builds on earlier geophysical insights and aims to reduce exploration risk by focusing on structural intersections favourable for gold deposition.

Drone Imagery Enhances Geological Mapping

Complementing the geophysical data, Austin Metals completed a high-resolution drone imagery survey covering prospective structural trends and BIF stratigraphy across key prospects. This survey enables more precise tracing of subtle faults and lithological contacts, which are often missed in regional imagery. The drone data also highlights surface alteration signatures such as iron staining and quartz veining, which can act as vectors toward mineralised zones.

By integrating these drone-derived insights with field mapping and geochemical data, Austin is refining its geological model and increasing confidence in drill target prioritisation. This methodical approach follows the company's recent deployment of drones to sharpen exploration focus at Brunswick Hill and surrounding areas drone imagery and field mapping.

Rock-Chip Sampling Provides Geochemical Clues

Targeted rock-chip sampling has been conducted on zones exhibiting structural complexity, shearing, and quartz veining along BIF stratigraphy. Austin Metals has submitted 53 new samples for multi-element assay, with results expected in early May 2026. While no visible gold was observed in these samples, the geochemical data will help identify pathfinder elements and alteration haloes critical for ranking drill targets.

The sampling program complements a substantial database of historic rock-chip results, including high-grade quartz and BIF samples from previous operators. This rich dataset, now disclosed with additional JORC Code and ASX Listing Rule compliance, underpins the company’s confidence in the structural controls identified. The focus on structurally driven targets aligns with Austin Metals’ strategy to emulate the successful Vadrians-style BIF gold model recently advanced at Brunswick Hill Vadrians-style BIF gold model.

Drilling Plans and Project Context

Austin Metals plans to commence reverse circulation (RC) drilling in the second quarter of 2026, targeting the priority zones defined by the integrated datasets. The drill program aims to test the geometry and continuity of BIF-hosted stratigraphy and structurally controlled gold mineralisation, with a focus on Brunswick Hill, Mt Sandy, and Golconda Well.

The Austin Gold Project is strategically located adjacent to Ramelius Resources’ Cue Gold Project, which includes the high-grade Break of Day deposit, and near Caprice Resources’ Island Gold Project with its recent Vadrians discovery. Austin Metals’ exploration is thus situated in a prolific gold province with proven mineralisation styles, enhancing the potential significance of its targeting efforts.
