OD6 Metals Uncovers High-Grade Copper VMS at Gulf Creek, NSW
OD6 Metals has confirmed significant high-grade copper-zinc-silver volcanogenic massive sulphide mineralisation in its first drilling campaign at Gulf Creek, NSW, marking a major step forward after 60 years of dormancy. The results validate the company’s geophysical targeting and open up promising extensional targets along a 3km strike.
- First drilling at Gulf Creek in 60 years reveals massive sulphide copper-zinc-silver mineralisation
- High-grade intercepts include 8m @ 1.41% Cu, 1.26% Zn, 7.08g/t Ag beneath historic workings
- Strong correlation between magnetic anomalies and mineralisation confirms targeting strategy
- Multiple untested extensional targets identified over ~3km strike length
- Exploration activities recommenced following NSW Resource Regulator approval
Historic Copper Project Reawakens
OD6 Metals has delivered a compelling update from its Gulf Creek Copper Project in New South Wales, where the first drilling in six decades has intersected high-grade volcanogenic massive sulphide (VMS) mineralisation. This early success not only confirms the presence of significant copper, zinc, and silver mineralisation beneath historic workings but also validates the company’s modern geophysical targeting approach.
The initial six holes drilled have revealed massive to semi-massive sulphide zones with standout intercepts such as 8 metres at 1.41% copper, 1.26% zinc, and 7.08 grams per tonne silver, including a higher-grade 5 metres at 2.13% copper. These results echo the historically mined grades that once made Gulf Creek one of NSW’s highest-grade copper mines before its closure in 1912.
Magnetics and Mineralisation: A Strong Link
One of the most significant technical takeaways is the strong relationship between magnetic anomalies and mineralisation. The high-grade sulphide mineralisation sits immediately in the hanging wall of the strongest magnetic body detected by drone magnetics, confirming the company’s targeting methodology. This correlation provides a robust framework for future exploration, particularly in identifying large-scale VMS systems.
Magnetic modelling has also highlighted multiple extensional target structures along strike, including the Big Bend, Eastern Limb, and Northwestern Zones. These untested targets cover approximately 3 kilometres of strike and extend to depths beyond 500 metres, presenting compelling opportunities for further discovery.
Regulatory Green Light and Next Steps
Exploration activities had been temporarily paused following directions from the NSW Resource Regulator but have now recommenced after receiving formal approval. OD6 Metals plans to advance with a Phase 2 drilling program, including at least one deep hole to around 400 metres for down-hole geophysics, aiming to test the extensional targets and deepen understanding of the mineral system.
Beyond drilling, the company intends to undertake mineralogical and metallurgical test work to assess the economic potential of the mineralisation. The presence of broad, low-grade disseminated copper mineralisation near surface in several holes suggests a larger mineralised system that could support a significant project scale.
Strategic Implications for OD6 Metals
Gulf Creek’s revival fits neatly into OD6 Metals’ broader strategy of advancing critical minerals projects in Australia. Alongside its rare earths-focused Splinter Rock Project in Western Australia, Gulf Creek offers exposure to a high-grade copper-zinc-silver VMS deposit with substantial exploration upside. The confirmation of mineralisation and the validation of geophysical targets enhance the project’s attractiveness and could materially impact the company’s valuation as drilling progresses.
While still early days, these results mark a pivotal moment for OD6 Metals, signaling the potential emergence of a significant new copper resource in NSW after decades of inactivity.
Bottom Line?
OD6 Metals’ Gulf Creek drilling confirms a promising VMS system, setting the stage for a potentially transformative copper discovery.
Questions in the middle?
- How extensive and continuous is the high-grade mineralisation along strike and at depth?
- What metallurgical characteristics will the mineralisation exhibit, and how might this impact processing?
- How quickly can OD6 Metals advance Phase 2 drilling and what regulatory or logistical hurdles remain?
