Legacy Minerals Secures CSIRO Partnership to Unlock Mt Carrington's Full Potential
The Legacy Minerals CSIRO collaboration represents a significant milestone for the company's Mt Carrington Project, as Legacy Minerals (ASX: LGM) has announced a strategic research partnership with Australia's premier scientific institution. The collaboration, supported by a $196,000 fund including a $50,000 CSIRO Kick-Start grant, targets advanced mineralogical studies at the flagship project hosting a substantial 115 million ounce silver equivalent (AgEq) Mineral Resource.
This partnership positions Legacy to leverage cutting-edge analytical techniques typically beyond the reach of junior explorers. Furthermore, it potentially transforms how the company approaches targeting and drilling across its extensive NSW gold-silver system.

Advanced Technology Meets Proven Resources
The Legacy Minerals CSIRO collaboration centres on applying sophisticated analytical methods—including SEM-TIMA (Scanning Electron Microscopy-TESCAN Integrated Mineral Analyser) and LIBS (Laser-Induced Breakdown Spectroscopy)—to better understand mineralisation controls across Mt Carrington's key deposits.
Key Technical Objectives:
- Improve understanding of alteration and structural controls on mineralisation
- Support more efficient targeting and extensional drilling
- Provide early-stage metallurgical insights
- Develop 2D and pseudo-3D alteration and structural models
The study will focus on five priority areas: Strauss, Kylo North, Guy Bell, White Rock North, and Gladstone deposits and prospects. In addition, the collaboration will analyse drill core and chip samples to identify mineral assemblages and alteration gradients that could guide future exploration.
| Analytical Technique | Purpose | Expected Outcome |
|---|---|---|
| SEM-TIMA | High-precision mineral identification | Quantitative mineral distribution mapping |
| LIBS | Rapid, scalable elemental analysis | Efficient targeting workflows |
| Structural Logging | Core and outcrop analysis | Enhanced structural understanding |
| MAIA Mapper | High-definition X-ray microscopy | Detailed ore sample characterisation |
Understanding Epithermal Systems: Educational Framework
Low-sulphidation epithermal systems like Mt Carrington form when hot, mineral-rich fluids rise from depth and deposit gold and silver in near-surface environments. These systems are particularly valuable because they often contain high-grade precious metals in relatively accessible locations.
The challenge lies in understanding the structural and alteration controls—essentially, the geological framework that channelled these precious metal-bearing fluids. Consequently, by mapping these controls precisely, Legacy can significantly improve drilling success rates and reduce exploration costs.
Key Characteristics of Epithermal Systems:
- Formation at shallow depths (typically less than 1,500 metres)
- Moderate temperature formation (150-300°C)
- Distinct alteration patterns that can guide exploration
- High precious metal grades concentrated in structural corridors
This explains why the Legacy Minerals CSIRO collaboration is particularly valuable: it provides Legacy with analytical capabilities to decode these complex geological relationships at a level of detail previously unavailable to the company.
Mt Carrington: Substantial Resource Base
Mt Carrington's existing 115 million ounce AgEq Mineral Resource provides a compelling foundation for this advanced technical work. The resource spans multiple deposits across a collapsed caldera structure, with a mining history dating back to the mid-1800s.
Current Resource Breakdown by Key Areas:
| Deposit | Classification | Tonnes (Kt) | Au (g/t) | Ag (g/t) | AgEq (g/t) | Contained AgEq (Koz) |
|---|---|---|---|---|---|---|
| Strauss | Indicated | 2,818 | 1.1 | 3.1 | 149 | 13,500 |
| Kylo | Inferred | 2,026 | 1.0 | 2.0 | 130 | 8,468 |
| Red Rock | Inferred | 8,605 | 0.5 | 7.4 | 84 | 23,239 |
| Lady Hampden | Indicated | 2,136 | 0.71 | 62 | 124 | 8,516 |
The scale of this existing resource base reinforces why improving targeting confidence is crucial. Furthermore, any enhancement in drilling efficiency or resource definition could have material implications for project economics.
Strategic Timing and Next Steps
The collaboration represents disciplined capital allocation ahead of Legacy's next drilling phase. By investing in advanced technical understanding upfront, the company aims to improve exploration efficiency and reduce geological uncertainty.
Expected Timeline and Deliverables:
- Integration of SEM-TIMA and LIBS analytical results with existing datasets
- Development of enhanced targeting frameworks
- Structural and alteration modelling to guide future drilling
- Early-stage metallurgical insights for future processing studies
Management Commentary
"Working with CSIRO gives Legacy access to advanced mineralogical techniques that are not typically available to junior explorers at this scale. By combining these methods with our existing geological and geochemical datasets, we believe the Company can materially improve its interpretation of the Mt Carrington system in a way that supports efficient capital allocation and long-term shareholder value creation."

Investment Thesis: Technology-Driven Exploration Excellence
This Legacy Minerals CSIRO collaboration represents several key investment themes for Legacy Minerals:
Technology-Driven Efficiency: Legacy is applying institutional-grade analytical techniques to improve exploration outcomes, potentially reducing drilling costs and improving success rates.
Resource Optimisation: With 115 million ounces AgEq already defined, any improvement in geological understanding could enhance resource confidence and support future development studies.
Strategic Partnerships: The CSIRO collaboration demonstrates Legacy's ability to access premium technical capabilities through strategic relationships rather than expensive internal infrastructure.
Systematic Approach: Rather than rushing into drilling, Legacy is investing in geological understanding—a disciplined approach that could yield superior long-term returns.
The combination of proven resources, advanced technical capabilities, and systematic exploration methodology positions Mt Carrington as a compelling exploration story with significant potential.
Technical Approach and Methodology
The CSIRO study is designed to address gaps in Legacy's current assessment of the Mt Carrington mineralised system. The existing approach relies on geochemistry, geological datasets, and historic drill core review. However, these methods have limitations in resolving mineral associations, alteration signatures, and structural relationships.
Combined SEM-TIMA and LIBS Workflow:
The study will employ a combined approach that leverages SEM-TIMA analytical precision with LIBS speed and scalability. According to the CSIRO proposal, this combined methodology allows quantitative mineral distribution to be mapped at a resolution and pace more relevant to exploration programs.
Integration with Existing Data:
The advanced analytical results will be integrated with portable X-ray fluorescence (p-XRF) and existing geochemical datasets. In addition, the study includes structural logging of oriented drill core and accessible outcrop. The study will also include up to four MAIA mapper scans of high-grade ore samples.
