Exultant Mining Advances Three Undrilled Cu-Au Targets in Macquarie Arc
Key Takeaways
- Exultant Mining (ASX: 10X) has commenced fieldwork at Watsons Prospect, the first of three undrilled copper-gold targets across its 100%-owned, 390km² Black Hammer Project in the Macquarie Arc — the same province hosting Cadia (~50Moz Au, ~9.5Mt Cu) and Cowal (8.9Moz Au).
- Watsons carries a 2.4km Cu-Zn soil anomaly with quartz-pyrite-chalcopyrite veining at surface, but gold was never included in the historical analytical suite — a critical gap the current program is designed to address, 2km along strike from the Shooters Hill and Chatham Valley gold mines.
- Porters Retreat hosts chalcopyrite at surface within a strongly altered monzonitic intrusion, with basement magnetic anomalies suggesting a larger intrusive system at depth and angular alluvial gold in the adjacent Retreat River providing a second exploration vector.
- Vermithor is a newly defined ~1km x 1km remanent magnetic anomaly generated from reprocessed airborne data, with its modelled core extending approximately 1.2km in depth and located less than 5km from the Footrot Au-Cu prospect.
- Assay results from the final three holes of the maiden Balerion drill program (BLRCDD004–006) remain pending, with Black Hammer fieldwork running concurrently to keep exploration active across two fronts simultaneously.
Three Cu-Au targets take shape at Black Hammer’s 390km² Macquarie Arc project
Exultant Mining (ASX: 10X) has commenced fieldwork at the first of three undrilled copper-gold targets across its 100%-owned, 390km² Black Hammer Project in the Macquarie Arc, New South Wales. The province is no stranger to scale, hosting Cadia (~50Moz Au and ~9.5Mt Cu) and Cowal (8.9Moz Au) as regional reference points for what the arc can produce.
The mobilisation advances Exultant’s exploration pipeline while assay results from the final three holes of the maiden Balerion drill program (BLRCDD004, BLRCDD005 and BLRCDD006) remain pending. With 12 prospects and historical workings identified across the project, the company is building a systematic, capital-efficient program rather than waiting on a single data point.

Three undrilled targets, three distinct geological stories
Each of the three priority targets carries its own geological rationale and a shared characteristic: none has been tested by drilling.
Watsons Prospect — 2.4km anomaly, never tested for gold
Historical soil sampling defined a coherent Cu-Zn anomaly extending for approximately 2.4km within the Rockley Volcanics of the Macquarie Arc. Surface expressions include quartz-pyrite-chalcopyrite veining, but there is a critical gap in the historical record: gold was never included in the analytical suite.
That omission matters, because Watsons sits approximately 2km along strike from the historical Shooters Hill and Chatham Valley gold mines. A land access agreement is already in place over the majority of the target area, and fieldwork has commenced, making this the most advanced of the three targets from an access perspective.
Porters Retreat — chalcopyrite at surface, porphyry signature below
Porters Retreat hosts outcropping, strongly altered monzonitic intrusive rocks carrying pyrite and chalcopyrite at surface. The intrusion displays quartz-chlorite-albite alteration, and first-pass lithogeochemical assessment indicates characteristics considered prospective for porphyry and epithermal Au-Cu systems.
The spatial association with angular alluvial gold in the Retreat River adds a further exploration vector. Basement magnetic anomalies beneath and adjacent to the mapped intrusive rocks may indicate a larger intrusive system at depth, though no drilling has yet tested the concept. Land access negotiations are underway.
Vermithor — a newly defined magnetic “bullseye”
Vermithor is the newest addition to the target list, generated from reprocessed airborne magnetic data rather than any historical surface program. The target presents as an approximately 1km x 1km remanent magnetic anomaly, with the strongest interpreted magnetic core modelled to extend approximately 1.2km in depth.
Its location carries strategic interest: it sits less than 5km from the Footrot Au-Cu prospect and along trend from historical IP chargeability and low-resistivity responses. The source of the anomaly has not been confirmed by fieldwork or drilling. Land access negotiations have commenced.
| Target | Key Feature | Mineralisation Style | Distance to Known Deposit | Drill Status |
|---|---|---|---|---|
| Watsons | ~2.4km Cu-Zn soil anomaly; quartz-pyrite-chalcopyrite veining; gold never assayed | Epithermal Cu-Au | ~2km along strike from Shooters Hill and Chatham Valley gold mines | Undrilled; fieldwork commenced |
| Porters Retreat | Chalcopyrite at surface; altered monzonitic intrusion; basement magnetic anomalies | Porphyry and epithermal Au-Cu | Within project area; alluvial gold in adjacent Retreat River | Undrilled; land access negotiations underway |
| Vermithor | ~1km x 1km remanent magnetic anomaly; modelled core ~1.2km depth | Intrusion-related / skarn Cu-Au (conceptual) | <5km from Footrot Au-Cu prospect | Undrilled; land access negotiations commenced |
What is the Macquarie Arc — and why does it matter for Cu-Au explorers?
The Macquarie Arc is an ancient volcanic arc sitting in central New South Wales, formed hundreds of millions of years ago when magma pushed through the Earth’s crust along a subduction zone. It is one of Australia’s most productive copper-gold provinces, and its geological pedigree is hard to argue with: Cadia and Cowal, both referenced earlier, are products of this same arc.
The Arc is particularly well regarded for hosting porphyry Cu-Au systems. A porphyry deposit is a large, typically low-grade bulk-tonnage copper-gold deposit formed as hot fluids circulate around a cooling igneous intrusion, depositing metals in the surrounding rock over a wide area. These are the systems that drive modern large-scale open-pit copper and gold mining.
Exultant’s ground covers prospective volcanic and intrusive Macquarie Arc rocks across 390km², the same geological canvas that produced the deposits now used as the yardstick for regional scale.

Staged approach keeps capital working hard while Balerion assays arrive
Rather than committing to drilling immediately, Exultant is applying a staged exploration model: surface reconnaissance, geochemistry, geophysics, then drilling. The logic is straightforward: refine the targets cheaply before allocating capital to more expensive drill programs.
This approach also creates a timing advantage. Black Hammer fieldwork advances while the technical team processes and integrates the remaining Balerion assay results, keeping exploration activity running across two fronts simultaneously.
The company’s next steps, as outlined in the announcement, are:
- Commence reconnaissance, mapping, rock-chip sampling and pXRF soil sampling at Watsons
- Progress land access agreements for Porters Retreat and Vermithor
- Receive and integrate the remaining Balerion assay results into an updated geological model
- Commence surface exploration at Porters Retreat and Vermithor once access is secured
- Submit priority soil and rock-chip samples for laboratory gold and multi-element analysis
- Undertake follow-up geophysics over targets supported by surface exploration results
- Advance the strongest Black Hammer targets toward drill testing
Brett Grosvenor, Executive Chairman
“With the maiden Balerion drilling program now complete and the remaining assays pending, we are able to redeploy our exploration team to Black Hammer and continue building our pipeline of drill targets. Watsons Prospect provides an immediate opportunity with Porters Retreat and Vermithor as two further, distinct exploration opportunities that have compelling geological, geochemical or geophysical characteristics but have never been drill tested. Our strategy has not changed, the objective of the 10X team is to undertake focused, low-cost fieldwork to identify the strongest parts of each target, validate those areas with laboratory geochemistry and geophysics, and then advance the highest-priority opportunities toward drilling.”
