Hermitage Drilling Yields 9m at 13g/t Gold and 17m at 1.23% Copper Equivalent
Emmerson Resources has reported significant high-grade copper, gold, cobalt, and bismuth mineralisation from recent drilling at its Hermitage Project in the Northern Territory, extending known mineralised zones and highlighting multi-metal potential.
- High-grade gold intercepts up to 43.1 g/t from 140m depth
- Copper equivalent grades reaching 5.84% over 2m intervals
- Multi-element mineralisation including cobalt, bismuth, and silver
- Mineralisation extended both at depth and along strike
- Plans underway for resource estimation and scoping study
Exploration Breakthrough at Hermitage
Emmerson Resources has announced compelling results from its recent reverse circulation drilling campaign at the Hermitage Project, located in the northern part of the Tennant Creek Mineral Field in Australia's Northern Territory. The drilling has intersected substantial zones of copper and gold mineralisation, with notable high-grade gold intercepts and significant multi-element content including cobalt and bismuth.
The standout intercept includes a 9-metre section grading 13.0 grams per tonne gold starting at 140 metres depth, with a remarkable 2-metre interval within this grading 43.1 g/t gold. Copper grades reached up to 1.57% in some intervals, while cobalt and bismuth were also present in economically interesting quantities. These results underscore the polymetallic nature of the deposit, which could translate into multiple revenue streams beyond just copper and gold.
Extending the Mineralised Envelope
The recent drilling program, comprising eight holes with seven intersecting the target ironstone host rock, has successfully extended mineralisation both down plunge to the west and up plunge to the east. Notably, the mineralised zones remain open in several directions, suggesting further upside potential. The intersections include wide zones of mineralisation, such as 53 metres at 0.90% copper equivalent and 17 metres at 1.23% copper equivalent, indicating robust continuity.
Emmerson’s Managing Director, Mike Dunbar, highlighted the significance of these results, emphasizing the high copper and gold grades alongside cobalt and bismuth byproducts. He noted that these combined elements could enhance the project's overall value proposition, particularly as the company advances towards a Mineral Resource Estimate and preliminary development studies.
Strategic Next Steps
Looking ahead, Emmerson plans to undertake detailed geological and structural modelling of the ironstone units to refine the understanding of the deposit's geometry. Further drilling is planned to test extensions of the mineralisation, particularly up-dip and up-plunge, to better define the resource potential. The company also intends to complete a Mineral Resource Estimate incorporating the latest drilling data and to initiate a scoping study supported by strategic partners CuFe Limited and Tennant Minerals Limited.
This methodical approach reflects a commitment to advancing the Hermitage Project from exploration towards development readiness, with a focus on unlocking the full value of its multi-element mineralisation. The presence of significant cobalt and bismuth, alongside copper and gold, could position Hermitage as a strategically important asset in the evolving metals market.
Context within Tennant Creek
Hermitage is part of Emmerson’s broader Tennant Creek tenement package, which includes several other copper and gold prospects such as Jasper Hills, Edna Beryl, and North Star. The mineralisation style at Hermitage is consistent with the region’s renowned ironstone-hosted deposits, sharing characteristics with major historical mines like Warrego. This regional context adds further weight to the potential significance of the recent drilling results.
While these results are promising, Emmerson cautions that the mineralisation is still at an exploration stage, with true widths variable and metallurgical recoveries yet to be confirmed. Nonetheless, the multi-element intersections and the open-ended nature of the mineralised zones provide a strong foundation for future work.
Bottom Line?
Emmerson’s latest drilling at Hermitage not only extends known mineralisation but also sets the stage for a multi-metal resource that could reshape its Tennant Creek portfolio.
Questions in the middle?
- How will upcoming metallurgical testwork impact the economic viability of cobalt and bismuth byproducts?
- What is the timeline for the Mineral Resource Estimate and how might it affect project valuation?
- Could further drilling reveal near-surface mineralisation suitable for early-stage development?
