Kingfisher Mining Hits 198g/t Silver at Broken Hill Prospect Near Historic District
Key Takeaways
- Kingfisher Mining's first drilling at Stephens Trig since 2017 returned 2m @ 17.5% Pb+Zn and 24 g/t Ag from 79m, confirming high-grade silver-lead-zinc mineralisation consistent with historical intercepts at the prospect.
- A standout 1m @ 198 g/t Ag result from hole 26STRC_020 at 111m depth adds a significant precious metals dimension to what is primarily a base metal system, appearing independently of the peak lead-zinc intervals.
- The Stephens Trig prospect is defined by a 1.5km lead-zinc geochemical anomaly that remains largely undrilled, with the 2026 program confirming mineralisation extends both at depth and along strike.
- Kingfisher's Mining and Processing Agreement with Broken Hill Mines, announced 4 March 2026, provides a framework to evaluate existing regional infrastructure as a potential lower-capital pathway to future production at Stephens Trig and Allendale.
- Copper Blow drilling approvals have been received from the NSW Resources Regulator with the program now expected to commence October 2026, adding a near-term catalyst at the company's flagship copper-gold asset.
High-grade silver-lead-zinc confirmed at Stephens Trig
Kingfisher Mining (ASX: KFM) has confirmed high-grade silver-lead-zinc mineralisation at its Stephens Trig prospect, located approximately 15 kilometres north of Broken Hill, NSW. The results come from the first drilling program at the site since 2017, validating a long-dormant Broken Hill-style target now re-entering active exploration under a 75% KFM / 25% Broken Hill Mines joint venture.
Key highlights from the program include:
- 5-hole RC program totalling 584 metres, targeting historically defined mineralisation
- Standout intercept: 2m @ 17.5% Pb+Zn and 24 g/t Ag from 79m (within 5m @ 7.4% Pb+Zn and 10 g/t Ag)
- Exceptional silver result: 1m @ 198 g/t Ag from 111m (hole 26STRC_020)
- Prospect defined by a 1.5km lead-zinc geochemical anomaly
- Results confirm mineralisation extends both at depth and along strike within the broader system

Drill results at a glance
The table below presents key intercepts from the 2026 RC program alongside historical comparators, illustrating grade continuity across the Stephens Trig system.
| Hole / Source | From (m) | Interval (m) | Pb+Zn (%) | Ag (g/t) |
|---|---|---|---|---|
| 26STRC_018 | 67 | 4 | 3.2% | 11 |
| 26STRC_018 incl. | 70 | 1 | 8.3% | 36 |
| 26STRC_018 | 79 | 5 | 7.4% | 10 |
| 26STRC_018 incl. | 79 | 2 | 17.5% | 24 |
| 26STRC_019 | 82 | 4 | 2.7% | 4 |
| 26STRC_020 | 85 | 1 | 9.3% | 40 |
| 26STRC_020 | 111 | 1 | 1.5% | 198 |
| 26STRC_021 | 57 | 3 | 2.4% | 6 |
| Historical [1] | 110 | 12 | 9.0% | 10 |
| Historical [2] | 51 | 6 | 10.2% | 10 |
| Historical [3] | 40 | 6 | 5.1% | 8 |
The 198 g/t Ag result in hole 26STRC_020 is a standout data point. It sits within a separate downhole interval from the peak base metal intercept in that hole, illustrating how high-grade silver zones can appear independently across the system and add a precious metals dimension to what is already a compelling base metal target.
Managing Director Chris Bittar
“These results are particularly encouraging given Stephens Trig has not seen drilling since 2017. Our first drilling program has validated the historical mineralisation and returned multiple high-grade silver-lead-zinc intersections, including a standout silver result of 198 grams per tonne.”
What is Broken Hill-style mineralisation?
Broken Hill-type (BHT) deposits are sediment-hosted, stratiform lead-zinc-silver systems.
Stephens Trig lies beneath shallow alluvial cover in a low-relief river valley and is poorly exposed. The prospect is underexplored. High-grade silver co-occurring alongside the lead-zinc mineralisation, as confirmed here, adds a precious metals component to what is primarily a base metal system, broadening the commercial case for further work.
A growing pipeline and a path to production
Stephens Trig joins an expanding Broken Hill portfolio
Kingfisher’s NSW tenure covers approximately 660km² across three proven mining districts. The company’s Broken Hill portfolio now comprises three validated pillars:
- Copper Blow — flagship copper-gold project, the most advanced asset in the portfolio
- Allendale — high-grade silver-lead-zinc project, already an established exploration target
- Stephens Trig — newly validated high-grade silver-lead-zinc prospect with confirmed depth and strike continuity
Each of these projects contributes to a diversified base and precious metals exposure across one of Australia’s most established mining addresses.
Mining and Processing Agreement — the strategic differentiator
Kingfisher’s broader Broken Hill strategy is supported by its Mining and Processing Agreement with Broken Hill Mines, announced on 4 March 2026. This agreement provides a strategic framework for evaluating potential future development opportunities using existing processing infrastructure in the Broken Hill region.
The practical implication is meaningful. Rather than being required to develop standalone processing facilities, Kingfisher has a framework to evaluate whether established regional infrastructure could support future production scenarios. That creates a potentially lower-capital pathway to development, subject to further exploration, resource definition, and technical and commercial studies. Stephens Trig and Allendale remain at exploration stage, and this agreement is a framework for evaluation at this point, not a confirmed development pathway.

What’s next for Kingfisher Mining
- Stephens Trig and Allendale: Integrate the 2026 RC results with historical exploration data and the geological model to assess mineralisation continuity and determine the next phase of exploration.
- Copper Blow (Drilling): Drilling approvals have been received from the NSW Resources Regulator. Program start is now expected in October 2026, delayed from September due to reduced drill rig availability following regional weather events in New South Wales. The program will focus on expanding the mineralised system and testing priority geophysical anomalies.
- Copper Blow (Metallurgy): Preliminary metallurgical testwork is scheduled to commence, assessing the metallurgical characteristics and potential processing pathways for the mineralisation.
- Copper Blow (Maiden Mineral Resource Estimate): Drilling, metallurgical testwork, and geological modelling are all progressing toward the completion of a Maiden Mineral Resource Estimate.
Across copper-gold and silver-lead-zinc targets, Kingfisher has multiple active drill catalysts converging over the near term. Combined with the Mining and Processing Agreement providing a potential infrastructure pathway, the company is building a diversified newsflow profile within one of Australia’s most proven mining addresses.
