One Drill Hole Just Put Mt Egerton on the Global Gold Map
Benz Mining (ASX: BNZ) has made an ultra-high-grade gold discovery beneath the historical Hibernian mine at Mt Egerton in Western Australia, returning 7 metres grading 223 grams of gold per tonne from the newly named Kilkenny zone.Â
The result is one of the richest drill intercepts reported by an ASX-listed junior explorer in recent memory, placing the Company firmly on the radar of gold investors and institutional watchers alike.

The highlight intercept is part of a wider interval in hole 26EGN013 that assayed 11 metres at 144.2 grams of gold from 270 metres downhole.Â
The discovery was made when an additional drillhole, added to test a revised structural model, intersected an exceptionally high-grade gold interval associated with quartz veining and pyrite in a gabbro sill, validating the model and uncovering Kilkenny.Â
The result has immediately elevated Mt Egerton’s status from a secondary brownfield project to a potentially district-scale discovery, with the company confirming that multiple stacked shoots along the same structural corridor are now firmly on the table.
Record Gold Prices Meet a Rare Bonanza-Grade Strike. Here Is Why Investors Should Pay Attention
For investors tracking the junior mining space, bonanza-grade results above 200 g/t gold are exceptionally rare and typically trigger significant re-ratings in equity markets.Â
Gold prices are trading near record highs in 2026, meaning any new high-grade discovery carries amplified economic significance compared to prior cycles.Â
Mt Egerton, about 800 km north of Perth, marks another brownfield gold project seeking new ounces linked to an old mine, now amped up by record metal prices.Â
For the broader mining community, the Kilkenny discovery reinforces the value of applying modern structural geology to historically underexplored ground.Â
Benz Mining is a pure-play gold exploration company dual-listed on the TSX Venture Exchange and the Australian Securities Exchange, and the Company’s key point of difference lies in its team’s deep geological expertise and the use of advanced geological techniques, particularly in high-metamorphic terrane exploration.Â
When a small explorer with a differentiated technical approach delivers a result like this, it signals that similar brownfield revivals could be playing out right across Australia’s gold belt.
The Team Behind the Drill Bit, Who Is Driving This Discovery
Benz Mining Corp (TSXV: BZ / ASX: BNZ) is the Company behind the discovery. CEO Mark Lynch-Staunton stated that what is most encouraging about the Kilkenny discovery is that it confirms the structural framework the team has been developing at the Mt Egerton Goldfield, and that the same geological team that unlocked the exploration potential at the flagship Glenburgh Project is now applying that same approach at Mt Egerton.Â
That geological team, not just the assets, is being positioned as a core competitive advantage.
On the analyst side, SCP Resource Finance noted that Benz’s A$94 million treasury should fund a more than 250,000-metre drill campaign this year across Glenburgh’s three main camps, Hurricane, Icon, and Thunderbolt, with Thunderbolt offering the strongest discovery upside because historic drilling there stopped at less than 100 metres depth.Â
A well-funded explorer with a proven technical team and now a bonanza-grade discovery is a combination that tends to attract serious capital quickly.
Deep in Western Australia’s Gascoyne: Why This Location Changes Everything
The discovery was made at the Mt Egerton Gold Project, situated in Western Australia’s Gascoyne region. Mt Egerton covers 179.59 sq. km and includes two granted mining leases.Â
The Kilkenny zone sits directly beneath the historic Hibernian mine workings at 270 metres depth, a position only identified after Benz’s team overhauled the structural model for the entire goldfield.

The location carries strategic weight beyond the drill result itself. Benz believes a similar exploration model may emerge at Mt Egerton, where multiple high-grade deposits across the district could ultimately develop as satellite ore sources supporting the future development of the Glenburgh Project.Â
With Mt Egerton sitting roughly 170 km from Glenburgh, Benz now holds two advancing gold stories within the same geological corridor, a rare logistical and economic advantage for a junior explorer.
A Century of Gold History: and How the Modern Discovery Timeline Unfolded
Benz officially announced the Kilkenny discovery on March 16, 2026, following an RC drilling programme conducted across 2025 and into early 2026. The Hibernian mine site itself carries more than a century of gold history:

- 1912–1924: Hibernian mine first operated, producing approximately 7,000 oz. of gold
- 1937–1953: The site re-opened under the name Pegasus for a second production period
- November 2024: Benz re-reported historical drilling data, including 9m at 107.2 g/t gold
- 2025–2026: Modern RC drilling programme commenced using a revised structural model
- March 16, 2026: Kilkenny discovery formally announced to ASX and TSX-V markets
Historical drilling had already shown how rich the system can be. Hibernian previously returned 9 metres at 107.2 g/t gold, 5 metres at 96.7 g/t, and 4 metres at 91.9 g/t in earlier work. Kilkenny’s 223 g/t result now sits well above even those impressive benchmarks.

20 Kilometres of Untested Strike: What Comes Next for Benz
The Kilkenny discovery is the direct result of a geological rethink rather than routine infill drilling. Benz geologists recognised that the best mineralisation was occurring by dilation of mafic host rocks between oblique shear zones at Hibernian, and at several other similar structural positions along the same mafic belt.Â
The revised structural model pointed to a new target position beneath the Hibernian mine and further to the east, where mapped shear zones interact with a folded gabbro sill.Â
This structural re-interpretation is precisely the kind of insight that transforms a modest brownfield programme into a district-scale discovery.
Looking ahead, Benz says more than 20 km of prospective strike across the goldfield remains effectively untested, with plans to drill Kilkenny extensions, test eastern targets, and continue mapping along the Hibernian corridor. The pipeline of priority targets includes:
- Galway Prospect — interpreted as a structural repeat of Hibernian on the same corridor
- Mako, Gift, and Trading Post — a second cluster approximately 2 km east of Hibernian
- Gift target — earlier drilling returned 17 metres at 6.8 g/t gold with broader gold and base-metal anomalism
The potential for a larger-scale emerging eastern gold camp within the Mt Egerton Goldfield is being followed up with a programme of systematic multi-element soils and planned mapping work through 2026.Â
With a strong treasury, a differentiated geological methodology, and a bonanza-grade intercept now in hand, Benz Mining enters the second half of 2026 with momentum few junior explorers can match.Â
Whether Kilkenny grows into a standalone resource or anchors a broader Glenburgh development case, the discovery has fundamentally changed the investment story around this company.
