Ausmon Kicks Off Base Metals Hunt 50km From World-Class Broken Hill Orebody
Ausmon Resources kicks off base metals hunt near world-class Broken Hill orebody
Ausmon Resources has commenced field-based base metals exploration at EL 9220 Enmore, a 341 km² tenement located 50 km south of Broken Hill in western New South Wales. The prospect sits within the Curnamona Province, the same geological system that hosts the world-class Broken Hill Pb-Zn-Ag orebody currently being mined adjacent to and south of Broken Hill township.
Access to the site is via the sealed Silver City Highway, then Ascot Vale tracks and fence lines. The program targets two prospects — Pine Creek and West Enmore — where geological structures, stratigraphy, and surface indicators have aligned to flag potential base metal mineralisation.
For investors, this announcement positions the company in a tier-one address with proven mineral system pedigree, ahead of assay results that will determine the next phase of activity.

Inside the Enmore exploration program
The field program comprises systematic soil sampling and geochemical screening across both target prospects. Samples will undergo initial field analysis before elevated readings are sent to an accredited laboratory for detailed multi-element testing.
Program mechanics:
- Soil sampling on 250m x 250m grids across Pine Creek and West Enmore Prospects
- Samples initially scanned by Olympus Delta pXRF
- Elevated base metal samples sent to ALS laboratory in Adelaide for gold and multi-element analyses
Why these targets were chosen
Both Pine Creek and West Enmore Prospects are intersected by NE-SW shear zones associated with NE-SW linear magnetic highs, which have been flagged as potential base metal targets. The targets were selected based on NE-SW shear zones intersecting favourable stratigraphic settings, including surface gossans.
The tenement is dominated by Redan Gneiss in the east and Edna and Farmcote Gneisses along with the Mulcula and Cues Formations. These rock units sit within the Thackaringa Group and underlying gneissic sequence, located stratigraphically below the Broken Hill Group that hosts the world-class Broken Hill orebody.
For investors, the convergence of multiple geological indicators — structural controls, favourable host rocks, surface gossans, and magnetic anomalies — at the same targets reduces early-stage exploration risk by focusing sampling on areas with stacked evidence of potential mineralisation.
The Broken Hill connection — why the geology matters
The Curnamona Province is one of Australia’s premier base metals addresses, home to the Broken Hill deposit, a globally significant Pb-Zn-Ag resource that has been in continuous production for over a century. Enmore sits within the same geological system, though in stratigraphy that underlies the Broken Hill Group host rocks.
Understanding the geological tools used in this early-stage program helps investors assess what results could mean. Soil sampling collects near-surface material that may carry geochemical traces of buried mineralisation. Gossans are weathered surface expressions of sulphide mineralisation below, acting as visual markers for exploration targeting. Shear zones are structural breaks in rock that can act as pathways for mineralised fluids, often concentrating metals in economically significant grades.
| Feature | Detail | Why it matters |
|---|---|---|
| Location | 50km south of Broken Hill | Proven world-class Pb-Zn-Ag address |
| Stratigraphy | Below Broken Hill Group | Same host system pedigree |
| Structure | NE-SW shear zones | Pathways for mineralisation |
| Surface signs | Gossans | Potential indicators of buried sulphides |
Positioning in a geological province with demonstrated endowment is the first filter in exploration. Enmore’s location within the Curnamona Province and stratigraphic setting below the Broken Hill Group provides the “why here” case for investors ahead of geochemical confirmation.

What comes next for Ausmon investors
The exploration roadmap follows a logical sequence: complete soil sampling across the grid, conduct field screening to identify elevated base metal readings, and submit anomalous samples to ALS Adelaide for detailed gold and multi-element analysis. Assay results will determine whether geochemical anomalies justify further work, including potential drill targeting.
Next steps:
- Complete soil sampling across Pine Creek and West Enmore grids
- Field screening via Olympus Delta pXRF
- Send elevated samples to ALS Adelaide for gold and multi-element analysis
- Assess anomalies to define potential drill-ready targets

For investors, assay results represent the key value inflection point. Confirmation of geochemical anomalies at either prospect would validate the geological targeting methodology and potentially advance the project toward drill testing. This announcement establishes exposure to a base metals exploration story in a tier-one province, with geochemical data as the next catalyst to watch.
