Cosmo Metals Locks in NSW Copper Licence After 4.69% Cu Surface Hit
Key Takeaways
- Cosmo Metals has been granted EL9946 (Carters Road) in NSW's New England Orogen, secured for the cost of a tenement application fee with no prior systematic modern exploration on the ground.
- A single reconnaissance rock chip sample returned 4.69% Cu and 5.78g/t Ag, confirming high-grade copper mineralisation at surface before any drilling has occurred.
- Over 1km of prospective Permian-aged Tonalite has been identified within the project area, targeting an intrusion-related Cu-Au deposit style analogous to the Mt Morgan mine (7.7Moz Au, 361,000t Cu historical production).
- Carters Road sits 40km south east of Cosmo's existing Nundle Project, with both projects straddling the same Peel–Manning Fault Complex — building a portfolio along a single mineralised corridor rather than acquiring isolated tenements.
- The forward work programme moves from data compilation and geological mapping through to rock chip sampling along the Peel–Manning Fault, with no drilling timeline yet disclosed.
Cosmo secures new copper exploration licence in NSW’s New England Orogen
Cosmo Metals (ASX: CMO) has been granted the Carters Road exploration licence (EL9946) in the southern New England Orogen of NSW, located approximately 40km south east of its Nundle Project. The grant followed field reconnaissance that returned a single rock chip sample grading 4.69% Cu and 5.78g/t Ag, a high-grade surface copper result that triggered a proactive tenement application over previously vacant ground.
This is a low-cost, geology-driven acquisition. The company secured the licence for the cost of an application fee, with no historic mining or systematic modern exploration previously conducted within EL9946.

Carters Road at a glance
| Item | Detail | Significance | Status |
|---|---|---|---|
| New tenement | EL9946, Carters Road | Expands NSW copper portfolio | Granted |
| Reconnaissance sample | 4.69% Cu, 5.78g/t Ag | High-grade surface copper confirmed | Single grab sample (rock chip) |
| Strike extent | Over 1km of prospective Tonalite | Targets intrusion-related Cu-Au | Mapping stage |
| Analogous target style | Mt Morgan-style Cu-Au deposit | Mt Morgan recorded production of 7.7Moz Au and 361,000t Cu between 1884 and 1981 (geological context only — Mt Morgan is not a CMO asset) | Geological targeting |
What is intrusion-related Cu-Au mineralisation — and why does it matter here?
A Tonalite is a coarse-grained igneous rock, similar in composition to granite, that forms when magma cools slowly deep within the Earth. When these intrusions push up through older volcanic sequences, the intense heat and chemically reactive fluids they carry can concentrate metals into economically significant copper and gold deposits. This is what geologists call intrusion-related Cu-Au mineralisation.
The Peel–Manning Fault Complex is the key structural feature at Carters Road. Extending over 270km, it is a major west-dipping fault zone that juxtaposes distinct geological terranes (blocks of ancient crust with differing origins), creating the fluid pathways and chemical conditions that favour Cu-Au mineralisation.
The Mt Morgan mine, located near Rockhampton in Queensland, is a geological analogue for what Cosmo’s technical team is targeting at Carters Road. Mt Morgan is classified as a VMS deposit (Volcanogenic Massive Sulphide, meaning metal-rich mineralisation formed from ancient seafloor hydrothermal activity) hosted in felsic volcanics intruded by a Permian-aged Tonalite complex. Mt Morgan is not an asset of Cosmo Metals; it is referenced purely to illustrate the deposit style being targeted.
At Carters Road, the combination of a Permian Tonalite intrusion, Tamworth Group volcanics, and proximity to a Serpentinite-bearing fault corridor mirrors this geological architecture.
What Cosmo found on the ground — and what comes next
Surface copper confirmed across 1km of prospective strike
Field reconnaissance by the Cosmo team identified outcropping copper oxide mineralisation associated with a Permian-aged Tonalite intrusion within Tamworth Group volcanics. Over 1km of prospective Tonalite has been identified within the project area.
The structural setting adds further interest. The Tonalite and volcanics sequence sits adjacent to, and south of, a Serpentinite sequence associated with the Peel–Manning Fault Complex, at a location where there is a major east–west offset of the fault package of more than 10km. According to the JORC Table 1 disclosure, EL9946 is 100% held by Galaxias Metals Pty Ltd. The announcement does not elaborate on the relationship between Galaxias Metals Pty Ltd and Cosmo Metals Ltd.
Importantly, there is no evidence of historic mining or systematic modern exploration within EL9946. This is effectively a blank slate.
Forward work programme
- Compilation of historical open-file exploration, geological and geophysical data across the broader area
- Review of regional and local geological and geophysical data to guide on-ground planning
- Ground truthing, geological mapping and rock chip sampling to define mineralisation trends along the Peel–Manning Fault and adjacent to the Tonalite
- Stakeholder engagement and advancing approvals for on-ground exploration activities
Managing Director’s perspective
Ian Prentice, Managing Director, Cosmo Metals
“We are very pleased to have expanded Cosmo’s copper prospective portfolio in the New England Orogen through good geological work and proactive tenement management, securing a zone of outcropping copper mineralisation with scope for a scale intrusion related Cu-Au discovery for the cost of a tenement application. We are looking forward to getting on the ground and following up on the reconnaissance grab sample that has already demonstrated the presence of high grade copper mineralisation at surface.”
The strategic logic is clear: low-cost entry into a geologically compelling corridor that the company is already active in through the nearby Nundle Project.

Carters Road in the context of Cosmo’s broader NSW strategy
Carters Road sits within the same New England Orogen footprint as Cosmo’s Nundle Project, located approximately 40km to the north west. Nundle straddles the Peel Fault and is also considered prospective for intrusion-related Cu-Au mineralisation, specifically at the Barnard Hut–Back Barb prospect area. The Barnard Hut prospect sits within a regional-scale magnetic high with a north-west trending strike of 4.2km and up to 1.6km wide.
Two projects, the same fault system, the same deposit style — this is portfolio building along a proven mineralised corridor rather than isolated tenement acquisition.
Beyond NSW, the company also operates the Kanowna Gold Project in WA, located approximately 13km north of Kalgoorlie and adjacent to the 7Moz Kanowna Belle gold mine, as well as the Yamarna Project in the Eastern Goldfields. The approach is diversified but focused, with copper-gold exploration in NSW running alongside gold-focused work in Western Australia.
