Legacy Minerals Strikes Gold: Wide Zones of Sulphide Veins Discovered at Thomson Project
Legacy Minerals (ASX: LGM) has completed its first drilling campaign at the Thomson Project in far northwest NSW, successfully intersecting wide zones of quartz-sulphide veins at both the F4 and Cut-B anomalies. The drill targets were defined by discrete, coincident zones of elevated magnetic and gravity data interpreted as having potential for intrusion-related gold and copper (IRG-Cu) style mineralisation.
Drilling Success Validates Exploration Model
The recently completed drilling campaign successfully intercepted quartz and quartz-pyrrhotite-pyrite veins with traces of sphalerite and chalcopyrite at both targets. These mineral-bearing structures are interpreted to be the source of the magnetic and gravity anomalies that guided the company's exploration strategy.
"Legacy Minerals is pleased to have achieved our objectives with the latest drilling at the Thomson Project, which intercepted wide zones of quartz-sulphide mineralisation at both target areas," said Legacy Minerals CEO & Managing Director, Christopher Byrne. "At the Thomson Project, we benefit from a district-scale, first-mover advantage, exploring a new frontier for mineral discovery."
Drilling reached top of basement at 84.2m (CBDD004) and 88.8m (F4DD001), continuing through variably hornfelsed and silica-carbonate altered meta-siltstone dominated packages with quartz veins extending to the end of both holes (600.2m and 460.3m respectively).
Historical Context Enhances Potential
The current exploration builds on encouraging historical drilling results at the Cut-B anomaly, which previously encountered 300m of alteration and elevated gold-copper anomalism, including:
- 1m at 6.73g/t Au from 370m
- 1m at 497g/t Ag, 0.13% Nb from 392m
- 0.7m at 0.5% Cu, 112g/t Ag, 4.2% Zn and 0.4% Sn from 411m
These historical results, combined with the company's recent drilling success, point to significant mineralisation potential across the Thomson Project area.
What Are Intrusion-Related Gold-Copper Systems?
Intrusion-related gold-copper (IRG-Cu) systems are a distinct class of mineral deposits formed when metal-rich fluids associated with magmatic intrusions circulate through surrounding rocks. These systems are characterised by:
- Association with reduced intrusions (often granodiorite or similar rock types)
- Distinct geophysical signatures (magnetic and gravity anomalies)
- Predictable metal zoning patterns (gold, copper, bismuth, tellurium)
- Potential for large-scale mineralisation
The presence of pyrrhotite (a magnetic iron sulphide) in the drill core is particularly significant, as this mineral often correlates with gold mineralisation in IRG-Cu systems. The identification of this mineral validates Legacy's geological model and targeting approach.
Future Exploration Plans
With initial drilling complete, Legacy Minerals is now focused on:
- Analysing drill core – Assay results expected within 6-8 weeks
- Testing the Cut-A Anomaly – Government approvals are underway for this promising target
- Follow-up drilling – Funding and approvals in place for additional holes at both Cut-B and F4 targets
The Cut-A anomaly represents a particularly compelling future target, with historical drilling having returned broad mineralised intervals including 377m at 0.1g/t Au from 225m to 602m, including 41m at 0.4g/t Au from 420m.
The Thomson Project: A District-Scale Opportunity
The Thomson Project covers an impressive 5,500km² of tenure in a frontier exploration region with characteristics similar to major IRG-Cu districts such as the Paterson Province in Western Australia. That region hosts significant deposits including Winu (2.8Mt Cu, 8Moz Au, 51Moz Ag) and Havieron (7Moz Au, 0.3Mt Cu).
The project area sits near the southern margin of the Thomson Orogen, close to the interpreted contact with the Lachlan Fold Belt and Delamerian Orogen. This geological setting creates an ideal environment for the formation of large mineral systems.
Investment Thesis: Why Legacy Minerals Stands Out
Legacy Minerals offers investors exposure to a frontier exploration play with several compelling advantages:
- First-mover advantage in an underexplored region with district-scale potential
- Multiple drill-ready targets identified through sophisticated geophysical analysis
- Initial drilling success validating the company's geological model
- Analogous to major discoveries in similar geological settings
- Well-funded exploration programme with approvals in place for continued drilling
The Legacy Minerals Thomson Project discovery marks an important milestone in Legacy's exploration journey. While assay results are still pending, the geological observations from the drill core support the company's targeting methodology and enhance the prospectivity of the broader project area.
Why Investors Should Follow Legacy Minerals
Legacy Minerals represents a compelling opportunity for investors interested in early-stage mineral exploration with significant upside potential. The company has:
- Secured a vast exploration territory in a frontier region with similarities to world-class mineral districts
- Demonstrated technical expertise in identifying and testing promising targets
- Developed a pipeline of projects across various commodities and stages of advancement
- Established a clear pathway for continued exploration and potential discovery
With assay results expected within 6-8 weeks and additional drilling planned, Legacy Minerals is positioned at the beginning of what could be a significant discovery journey at the Thomson Project. For investors seeking exposure to early-stage exploration with substantial upside potential, Legacy Minerals warrants close attention in the coming months.
