Benz Announces Widespread Tungsten Mineralisation Across the Glenburgh Gold System

HIGHLIGHTS:
- Tungsten mineralisation confirmed across entire 12km Glenburgh mineralised corridor within the mining lease. Elevated tungsten concentrations via routine ICP-MS analysis are observed closely associated with gold mineralisation across the entire system, particularly within higher-grade gold zones.
- Fusion digest re-assays have confirmed tungsten (WO3) in the following RC holes:
- 79m at 4.4g/t gold* from 534m (25GLR023) containing internal (WO3) intervals of:
- 26m at 0.24% WO3
- 5m at 0.11% WO3
- 44m at 4.6g/t gold* from 475m (25GLR070) containing internal WO3 interval of:
- 17m at 0.09% WO3
- 25m at 10g/t gold* from 568m (26HZ002) associated with a broader WO3 interval of:
- 33m at 0.1% WO3
- 79m at 4.4g/t gold* from 534m (25GLR023) containing internal (WO3) intervals of:
- XRD and SEM analysis confirm tungsten occurs predominantly as coarse-grained scheelite and ferberite (iron rich wolframite)
- Preliminary field observations demonstrate coarse scheelite and ferberite mineralisation can produce visible tungsten-rich concentrates through simple hand panning techniques, supporting potential gravity recovery pathways. Formal tungsten metallurgical testwork has commenced alongside ongoing gold metallurgical studies at ALS Metallurgy
- Glenburgh drilling ramp-up and pre-development programs underway: Benz is ramping up to 12 RC shifts across Hurricane, Icon and Thunderbolt Camps, alongside advancing metallurgical, geotechnical and orebody knowledge programs, reflecting increasing confidence in Glenburgh emerging as a large-scale multi-million-ounce gold system

CAUTIONARY STATEMENT ON VISUAL ESTIMATES OF MINERALISATION
References in this announcement to visual results are from geological observations of drill core. Visual estimates of mineral abundance should never be considered a proxy or substitute for laboratory analyses where concentrations or grades are the factor of principal economic interest. Visual estimates also provide no information regarding impurities or deleterious physical properties relevant to valuations. Assays are pending and will be reported when available.
Benz CEO, Mark Lynch-Staunton, commented:
"Historically, tungsten at Glenburgh was largely viewed as a pathfinder element associated with gold mineralisation. What is becoming increasingly clear through ongoing drilling and mineralogical work is that tungsten is not isolated to a single area, but is emerging as a widespread component of the broader Glenburgh mineralised system.
"Importantly, our focus remains firmly on gold. The scale and consistency of the gold system developing across Glenburgh is what continues to drive our conviction in the project. The tungsten mineralisation occurs within the same mineralised package being targeted by our drilling programs and therefore has the potential to represent an additional by-product value stream alongside any future gold mining operation.
"The confirmation of coarse-grained scheelite and ferberite through XRD and SEM analysis is also particularly encouraging from a metallurgical perspective. In several intervals, simple hand panning techniques have produced visible tungsten-rich concentrates, highlighting the coarse-grained nature of the mineralisation and supporting the potential suitability of conventional gravity recovery methods, subject to ongoing metallurgical testwork.
"The growing scale and continuity emerging across Hurricane, Icon and now Thunderbolt Camp continues to strengthen our confidence that Glenburgh is evolving into a large-scale multi-million-ounce gold system. The geological consistency we are seeing across multiple mineralised camps has supported a major planned ramp-up in drilling activity, with Benz gearing up toward one of the largest active gold exploration drill programs currently underway in Australia.
"We believe Glenburgh is continuing to evolve into a globally significant gold system, with widespread tungsten mineralisation throughout the broader gold system further reinforcing the scale, fertility and broader metal endowment emerging across the project."
Tungsten Mineralisation Recognised Across all Three Glenburgh Camps
Tungsten mineralisation has been confirmed across the Icon and Hurricane Camps through routine four-acid digest ICP-MS assays, while recent soil geochemical programs at the emerging Thunderbolt Camp have outlined some of the strongest and most extensive tungsten-in-soil anomalies identified across the Glenburgh Gold System to date. Importantly, the tungsten anomalism at Thunderbolt occurs closely associated with anomalous gold mineralisation, further reinforcing the scale potential emerging across the broader camp.
Elevated tungsten concentrations are observed throughout the broader Glenburgh gold mineralised package, with higher-grade tungsten zones commonly associated with higher-grade gold mineralisation, while more moderate tungsten concentrations are widespread throughout the broader bulk-tonnage gold mineralisation currently being targeted through ongoing drilling programs.
Benz is currently undertaking a systematic re-assay program targeting intervals with elevated tungsten anomalism identified through routine four-acid digest geochemistry. Significant tungsten mineralisation associated with high-grade gold intercepts so far include:
- 79m at 4.4g/t Au from 534m in 25GLR023, containing internal tungsten intervals of:
- 26m at 0.24% WO3
- 5m at 0.11% WO3
- 25m at 10g/t gold from 568m in 26HZ002 associated with a broader tungsten interval of:
- 33m at 0.1% WO3
- 44m at 4.6g/t Au from 475m in 25GLR070, containing an internal tungsten interval of:
- 17m at 0.09% WO3
- 16m at 0.01% WO3
The tungsten assays reported in this release represent only a subset of intervals currently being re-assayed for tungsten using fusion digest methods. However, routine four-acid digest ICP-MS multi-element geochemistry completed across the broader Glenburgh Gold System has consistently identified elevated tungsten anomalism throughout extensive bulk-tonnage gold mineralisation, indicating tungsten mineralisation is widespread across the system rather than restricted to isolated high-grade occurrences.
Management believes the widespread occurrence of tungsten throughout the same large-scale bulk-tonnage mineralised packages currently being targeted for substantial gold resource growth may have significant implications for the broader tungsten endowment emerging across the Glenburgh Gold System.

Expanded Tungsten Assaying
The Company notes that four-acid digest techniques may under-report tungsten concentrations where resistant tungsten-bearing minerals such as scheelite and ferberite are present, as these minerals may not be fully digested using partial digest methods.
Accordingly, lithium borate fusion digest methods are considered more appropriate for quantifying WO3 concentrations associated with scheelite and ferberite mineralisation.
Benz is currently undertaking a systematic re-assay program targeting intervals with elevated tungsten anomalism identified through routine four-acid digest geochemistry to ensure WO3 concentrations are not under-reported across the broader Glenburgh Gold System.
Initial lithium borate fusion results have demonstrated materially elevated WO3 concentrations relative to historical four-acid digest results, reinforcing the potential scale of tungsten mineralisation emerging across the system.
Accordingly, the tungsten intervals reported in this release are limited to intervals assayed using lithium borate fusion methods. The Company will continue to release results of further re-assaying in batches over the coming months.
Metallurgical Testwork
Mineralogical studies completed to date, including XRD and SEM analysis, confirm tungsten occurs predominantly as coarse-grained scheelite and ferberite.
Preliminary field observations indicate tungsten-rich concentrates can be produced through simple hand panning techniques (figure 3 and 4), highlighting the coarse-grained nature of the mineralisation and supporting the potential suitability of conventional gravity recovery methods, subject to ongoing metallurgical testwork.
Formal tungsten metallurgical testwork has commenced alongside the broader gold metallurgical program currently underway at ALS Metallurgy.

Glenburgh Drilling Ramp-Up Underway
Benz is currently ramping up drilling activities across the Glenburgh Gold System to 12 operational RC drill shifts across the Hurricane, Icon and Thunderbolt Camps, representing one of the largest active gold exploration drilling programs currently underway in Australia.
The scale-up in drilling activity reflects increasing management confidence that Glenburgh is emerging as a large-scale multi-million-ounce gold system with substantial long-term growth potential across multiple mineralised camps.
A diamond drill rig has now mobilised to support metallurgical, geotechnical and broader orebody knowledge programs as Benz advances multiple pre-development workstreams in parallel with ongoing exploration drilling.
Glenburgh - A New Frontier Gold District
The 100%-owned Glenburgh Gold Project is rapidly emerging as a new frontier gold district with multi-million-ounce potential. Located in Western Australia's Gascoyne region, Glenburgh hosts an 18-20 kilometre mineralised corridor anchored by the large-scale Icon-Apollo trend and the high-grade Zone 126 system.
Glenburgh's unique combination of thick, bulk-style gold mineralisation (Icon-Apollo) and multiple high-grade underground lenses (Zone 126) positions it as a rare opportunity in the Australian gold sector. With gold prices at record levels, the ability to develop both large-scale open pit and underground operations offers exceptional leverage and growth potential.
