Exultant Mining Secures the Swatchfield Licence, Unlocking an Underexplored Gold Target in NSW's Macquarie Arc
Exultant Mining (ASX: 10X) has announced the grant of Exploration Licence EL9913, known as "Swatchfield," by NSW Resources, materially expanding the company's Black Hammer Project near Oberon, New South Wales. Exultant Mining secures the Swatchfield licence for Black Hammer gold target in NSW, adding approximately 53 km² across 17 map units to what is now a contiguous tenure package totalling roughly ~390 km² — all sitting within the historically productive and largely underexplored Macquarie Arc.
The significance here extends beyond simply adding ground. Swatchfield brings with it a compelling set of historical indicators — including rock chip results up to 10.67 g/t Au — alongside a geological setting that draws meaningful comparisons to the nearby Lucky Draw Mine, a past producer that yielded 1.41 Mt at 4.2 g/t Au from analogous intrusion-related mineralisation.
Despite these encouraging signals, the area has seen only limited shallow historical drilling, leaving the targets essentially open to modern, systematic exploration.

What Has Been Granted and Why It Matters
The Black Hammer Project now consolidates three exploration licences into a single, unbroken landholding:
| Licence | Name | Area |
|---|---|---|
| EL9332 | Porters Retreat | Part of ~390 km² total |
| EL9826 | Tuglow | Part of ~390 km² total |
| EL9913 | Swatchfield (newly granted) | ~53 km² |
The project sits within the Macquarie Arc — a geological belt in central NSW recognised for hosting significant gold and copper-gold deposits. The addition of Swatchfield is strategically meaningful because it secures tenure over two distinct and previously underdrilled target types within the one licence: the Swatchfield Prospect and the Isabella Granite contact zone.
"We believe the combination of encouraging historical results, favourable geology and minimal modern exploration provides Exultant with a compelling opportunity for potential new discoveries at Black Hammer."
— Brett Grosvenor, Executive Chairman, Exultant Mining
Two Targets, One Licence: Understanding the Opportunity
The Swatchfield Prospect
Located within the northern portion of EL9913, the Swatchfield Prospect was first identified through regional drainage sampling and subsequently confirmed by rock chip sampling. The headline result — 10.67 g/t Au — is difficult to ignore, particularly given the minimal follow-up work conducted to date.
Key facts about the Swatchfield Prospect include:
- Mineralisation interpreted to be hosted within a gossanous sandstone unit at the contact between porphyritic dykes and the Rockley Volcanics
- Historical exploration included 50 RAB drillholes for 374 metres and 2 RC drillholes for 77 metres — both programmes shallow and limited in scope
- The RC drilling, while returning no significant gold intersections, did detect minor copper mineralisation, including 10 m at 0.13% Cu from 10 m in hole SWRC002
- Critically, the historical drilling was conducted before the development of intrusion-related gold models now recognised elsewhere in the region — meaning these targets were never tested with a modern geological framework in mind
The Isabella Granite Contact Zone
Approximately 2.5 km south of the Swatchfield Prospect lies a separate and potentially more compelling target: the contact aureole of the Isabella Granite. Furthermore, the following indicators collectively strengthen the case for exploration:
- At least nine rock chip samples from the granite contact have returned anomalous gold values above 0.1 g/t Au, with a peak value of 1.5 g/t Au from a siltstone sample
- These anomalous samples spatially coincide with magnetic highs around the margin of the Isabella Granite — a geophysical indicator that adds independent support for mineralisation potential
- This mineralisation style — intrusion-related gold at a granite contact — has never been systematically drilled within the Swatchfield licence area
- The nearby Lucky Draw Mine, located approximately 17 km west of EL9913, produced 1.41 Mt at 4.2 g/t Au from an analogous geological setting, providing a real-world analogue for what may exist at the Isabella Granite contact
The key takeaway is that historical exploration in this area was predominantly focused on porphyry copper-gold mineralisation, which largely failed. In doing so, explorers effectively overlooked the intrusion-related gold model now applied to prospects like Lucky Draw — leaving a genuinely underexplored target sitting in plain sight.
Understanding Intrusion-Related Gold Mineralisation
For investors less familiar with exploration geology, one concept is central to understanding why Exultant is excited about the Isabella Granite contact: intrusion-related gold mineralisation (IRGM).
When magma intrudes into surrounding rocks and cools to form a granite body, heat and fluids are expelled outward into the surrounding "contact aureole" — the zone of rock immediately adjacent to the granite. These fluids can carry dissolved gold and deposit it as they cool and react with the host rocks. The result can be gold mineralisation developed in the zone immediately surrounding the granite contact.
This is precisely the model attributed to the Lucky Draw Mine, which sits in an analogous geological position approximately 17 km to the west of EL9913. The Isabella Granite contact within Swatchfield has never been adequately tested for this type of mineralisation — despite the presence of gold-anomalous rock chips and coincident magnetic highs that are consistent with such a model.
Why this matters to investors: Intrusion-related gold deposits can be large, relatively predictable in terms of their spatial relationship to the causative granite, and are amenable to discovery through systematic geophysics and geochemistry followed by targeted drilling. The fact that the Isabella Granite contact has produced anomalous rock chips, aligns with magnetic responses, and sits in the same regional framework as a known mine, makes it a high-priority, drill-ready target once Exultant completes its current programme at Balerion.

What Comes Next: Exploration Roadmap for Black Hammer
Exultant's immediate focus remains on the maiden drill programme at its Balerion project. The company has been clear that Black Hammer activities, including Swatchfield, will be advanced following the completion of that programme. The planned work programme for EL9913 is structured to systematically test both priority targets:
- Field mapping and geological model updates to refine target vectors
- Soil and rock chip sampling programmes across the licence, particularly around the Isabella Granite contact
- Geophysical surveys to better define the magnetic anomalies and identify drill targets
- A drilling programme designed to test the intrusion-related gold model at the Isabella Granite contact and to follow up on the Swatchfield Prospect with modern geological understanding
Priority targets identified:
- The contact aureole of the Isabella Granite, supported by coincident gold anomalism and magnetic highs
- The Swatchfield Prospect, which has never been tested at depth or with the benefit of modern intrusion-related gold models
The Investment Case: First-Mover Advantage on an Underexplored System
The grant of EL9913 strengthens Exultant Mining secures the Swatchfield licence for Black Hammer gold target in NSW in several ways that are relevant to investors assessing the company's exploration pipeline.
Scale of landholding: At approximately ~390 km², Black Hammer is a substantial, contiguous tenure package within an established gold district. Size matters in exploration — it provides room to discover and develop multiple targets across a single administrative package.
Quality of historical data: The rock chip database across EL9913 is extensive, with over 400 historical samples collected by major companies including Renison Gold Fields, RGC Exploration, Newmont, and Anglo American. The presence of results up to 10.67 g/t Au and widespread anomalism in the Isabella Granite contact zone confirms the ground is genuinely mineralised — not simply anomalous.
Unexplained anomalism: The Isabella Granite contact has produced at least nine rock chip samples above 0.1 g/t Au, coincident with magnetic highs. No follow-up drilling has tested this target for intrusion-related gold. Consequently, this represents a concrete, identified gap in the historical exploration record.
Analogue proximity: Lucky Draw Mine — 1.41 Mt at 4.2 g/t Au from an analogous geological setting just 17 km away — provides a tangible benchmark for what intrusion-related gold mineralisation in this district can look like. It is not a guarantee of discovery, but it establishes a credible geological rationale for the model being applied.
Minimal modern exploration: The fact that this ground has seen only shallow, narrowly scoped historical drilling — all conducted before modern intrusion-related gold models were applied in the region — means the primary targets remain essentially untested by contemporary exploration methods.

Why Investors Should Watch Exultant Mining
Exultant is building a portfolio of gold exploration assets across a high-quality geological address. The Swatchfield licence grant is the kind of tenure move that often precedes meaningful discovery-stage news — it secures the ground, establishes the geological rationale, and sets up a systematic programme to test targets that have never been properly evaluated.
The company's dual-project strategy — actively drilling at Balerion while securing and de-risking Black Hammer — allows investors to follow a near-term catalyst (Balerion drilling results) while also tracking the development of a longer-term, potentially high-impact opportunity in Swatchfield.
With the licence now formally in hand, Exultant has the legal and operational foundation to advance what it describes as a "compelling opportunity for potential new discoveries" — backed by real historical data, a credible geological model, and a track record from the nearby Lucky Draw Mine that confirms the district is genuinely capable of hosting economic gold.
Key Takeaway: Exultant Mining (ASX: 10X) has secured a strategically important new licence within its ~390 km² Black Hammer Project, adding an underexplored gold target supported by rock chip grades up to 10.67 g/t Au and an untested intrusion-related gold model at the Isabella Granite contact — analogous to the nearby Lucky Draw Mine. With Balerion drilling underway and Black Hammer exploration to follow, investors have multiple near-to-medium-term catalysts to monitor.
