Benz Announces High-Grade Gold Multiplies at Icon as New Hinge Zones Emerge

Benz Announces High-Grade Gold Multiplies at Icon as New Hinge Zones Emerge

NE-plunging hinge zones emerge as an important and repeatable driver of ounce growth across Icon Camp

HIGHLIGHTS:

  • 41m at 14.5 g/t Au from 260m in 26CN079
  • 75m at 2.3 g/t Au from 253m in 26CN064
  • 39m at 3.6 g/t Au from 186m, including 8m at 15.6 g/t Au from 192m, in 26CN074
  • 62m at 2.5 g/t Au from 179m in 26CN073 within a broader 102m at 1.7 g/t Au
  • Previously reported Benz results: 25m at 16.53 g/t Au in 26CN029, 95m at 4.3 g/t Au in 25GLR232 and 47m at 5.1 g/t Au in 25GLR237, are now interpreted to form part of the NE-plunging high-grade hinge systems at Icon.
  • Systematic drilling within the established mineralised footprint is proving to be an ounce growth driver comparable to extensional drilling along strike and at depth. As drilling tightens, new NE-plunging high-grade hinge zones keep emerging, unlocking substantial new ounce potential from within the existing footprint.
  • High-grade gold at Icon is increasingly associated with NE-plunging fold hinge zones, closely mirroring the structural architecture observed at the Hurricane camp.
  • Benz's baseline 50m by 25m drilling pattern is generating substantial additional mineralisation potential within the existing Icon footprint.
  • The next phase of drilling will focus on completing the planned baseline drilling pattern across the Hurricane, Icon and Thunderbolt camps to ensure high-grade hinge zones are fully resolved and captured in the geological model prior to maiden resource in H1 27.

Benz Mining Corp. (ASX: BNZ) (TSXV: BZ,OTC:BENZF) ("Benz" or the "Company") is pleased to report further exceptional gold results from systematic drilling at the Icon deposit, part of the Company's Glenburgh Gold Project in Western Australia.

The latest results demonstrate that increasing drill density at Icon is doing considerably more than confirming previously identified mineralisation. It is providing the geological resolution required to identify additional fold hinges and high-grade gold positions that could not be resolved by earlier, wider-spaced drilling.

In addition, the planned drill lines also extend beyond the currently interpreted mineralised trends, providing significant potential for further discoveries and continued growth across Glenburgh.

As Benz progressively drills Icon on its baseline 50m by 25m pattern, additional NE-plunging hinge zones are emerging as important controls on high-grade gold mineralisation and potential drivers of future ounce growth. Earlier explorers missed these high-grade hinge zones in broader spaced shallow drilling which Benz first identified in early 2026 with intercepts such as:

  • 95m at 4.3g/t Au from 13m in 25GLR232
  • 29m at 8.8g/t Au from 84m in 25GLR190
  • 47m at 5.1 g/t Au from 55m in 25GLR237
  • 82m at 2.2g/t Au from 32m in 25GLR196

See ASX release dated 28 January 2026 for further details.

The same structural architecture is evident at the Hurricane camp, strengthening the Company's confidence that NE-plunging fold hinges represent an important and repeatable control on the distribution of high-grade gold across Glenburgh.

In a tightly folded mineral system such as Glenburgh, increasing geological resolution can materially change the understanding of the mineralised architecture. What may initially appear to be a broad mineralised envelope can resolve into multiple fold hinges, limbs and high-grade shoots as drilling advances.

Systematic drilling at Icon is therefore not simply increasing confidence in known mineralisation. It is revealing additional high-grade positions and generating substantial new mineralisation potential within the existing drilled footprint.

The results released today demonstrate the value of this approach and have the potential to add significantly to future contained ounces within an already exceptionally well-endowed gold system.

Importantly, the Company's baseline drill lines are not restricted to the currently interpreted mineralised trends. The 50m by 25m drilling pattern extends into areas outside the existing interpretation, providing further opportunities to identify previously unrecognised mineralised positions.

The program is therefore delivering on two fronts: revealing additional high-grade gold within the known Icon system while continuing to test substantial upside beyond the currently interpreted mineralised trends.

Management Commentary

Benz Chief Executive Officer, Mark Lynch-Staunton, commented:

"What excites us at Icon is that every new drill line seems to reveal more of the system. As drilling tightens, new NE-plunging high-grade hinge zones keep emerging, unlocking substantial additional ounce potential within the existing footprint.

"We are advancing Glenburgh at a pace that very few gold projects in Australia can currently match. This is one of the country's most aggressive drilling campaigns, and we are maintaining that momentum because systematic drilling is adding value to the project so quickly.

"Our immediate priority is to complete the baseline drilling across Hurricane, Icon and Thunderbolt, where drilling is now underway for the first time. These high-grade hinges can make an enormous contribution to contained ounces, and we want to ensure they are properly resolved and captured in the geological model.

"In parallel, we are advancing permitting and development activities. Glenburgh already benefits from a mature permitting position, giving us a clear and potentially rapid pathway forward as the resource work progresses. Tungsten re-assaying is also underway to assess the potential contribution of another strategically important metal.

"Approximately 80% of our maiden Exploration Target was already drill-constrained. We are not drilling to establish whether the target exists. We are completing the baseline drilling and geological work required to properly resolve the system and support the conversion of this substantial drill-supported inventory into a maiden Mineral Resource.

"The reason we are so confident about Glenburgh's scale is that the geology supports it. We have the craton-margin architecture, clear evidence of a huge magmatic-hydrothermal engine and a highly reactive sedimentary basin capable of trapping and concentrating enormous volumes of gold. These are the ingredients that build giant gold systems.

"The high-grade hinges emerging at Icon and Hurricane are part of something much bigger. This is not a one-deposit or one-camp story. We believe Glenburgh has the scale, architecture and geological engine to keep delivering new gold well beyond what we have defined today, with the potential to become truly world class.

"The Exploration Target was always intended as a starting point, not a limit. We look forward to delivering a maiden Mineral Resource Estimate which, based on the scale of the drill-constrained inventory already defined in the target, has the potential to rank amongst largest maiden gold resources reported on the ASX in recent years.

"The more we drill Glenburgh, the more gold it gives us. We believe this is just the beginning."

Glenburgh Geology: Makings of a Giant Gold System at Glenburgh

Benz has previously outlined the geological characteristics that point to Glenburgh being part of a large magmatic-hydrothermal mineral system. Continued drilling, multi-element geochemistry and geochronology are now refining that interpretation and providing greater clarity on how the different components of the system fit together.

While the precise deposit classification remains secondary, the fundamental geological processes identified by Benz are those associated with the formation of world-class mineral systems.

Through multi-element geochemistry, geochronology and systematic drilling, Benz is looking back through the effects of high-grade metamorphism and progressively reconstructing a vast, approximately 20 km-scale magmatic-hydrothermal alteration cell.

The developing model indicates that this system transported and concentrated gold, tungsten and iron within a volcano-sedimentary basin positioned along the margin of the Yilgarn Craton.

Benz believes Glenburgh contains three fundamental ingredients required to develop a giant gold system:

1. Crustal-scale structural architecture

Glenburgh is positioned along a craton margin where deep-seated breaks in the lithosphere created direct pathways between the mantle and the crust.

These long-lived structures provided the architecture required to focus magmas, heat and mineralising fluids through the Glenburgh system.

2. Magmatic heat, fluids and metals

Mantle-derived magmatic intrusions provided a powerful source of heat and metal-rich hydrothermal fluids.

This heat engine drove the development of a vast hydrothermal alteration cell capable of transporting gold and other metals through the broader Glenburgh system.

3. Geochemically reactive sedimentary basins

The mineralising fluids interacted with highly reactive rocks and basin-derived brines within the volcano-sedimentary sequence.

These reactive sedimentary rocks provided an effective environment for the trapping and concentration of huge volumes of gold.

The combination of crustal-scale structural architecture, a powerful magmatic-hydrothermal heat engine and a highly reactive sedimentary basin provides the geological framework for a potentially exceptional gold system.

Plan Ahead: Completing the Baseline Drill-Out Across Glenburgh

The next phase of drilling will focus on completing Benz's baseline 50m by 25m drilling pattern across all three principal camps at Glenburgh: Hurricane, Icon and Thunderbolt.

The objective is to ensure that the high-grade NE-plunging hinge zones are systematically identified, properly resolved and incorporated into the geological model. These hinge positions can make a significant contribution to contained gold but may not be adequately defined by wider-spaced drilling.

Benz has already observed this effect through closer-spaced drilling within the Icon data cube. As geological resolution increased, additional high-grade mineralisation and structural positions emerged that were not apparent from the earlier drilling pattern, as reported in the Company's announcement dated 28 January 2026.

This experience has reinforced the importance of completing the baseline drilling pattern across each of Glenburgh's major camps before the broader geological and mineralisation models are finalised.

The program is designed to ensure that high-grade hinge zones are not left behind simply because the drilling was too widely spaced to identify or connect them.

At the same time, the 50 m by 25 m drill lines will continue to extend beyond the currently interpreted mineralised trends, providing opportunities to identify additional folds, hinge zones and previously unrecognised mineralisation.

Glenburgh continues to demonstrate a compelling characteristic: the more systematically Benz drills the system, the more gold it defines.

The repeated emergence of high-grade hinge zones within broad mineralised envelopes reinforces Benz's view that Glenburgh is a phenomenally well-endowed gold system with substantial potential for continued ounce growth.

Appendix 2: JORC Tables
JORC Code, 2012 Edition – Table 1 report template

Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections)

Criteria Commentary
Sampling techniques
  • Results are part of BNZ's RC drilling campaign at the recently acquired Glenburgh Gold Project situated ~285 km east of Carnarvon via Gascoyne Junction, WA.

  • RC drilling samples were collected as 1m single samples.

  • Each sample collected represents each one (1) metre drilled collected from the rig-mounted cone splitter into individual calico bags (~3kg).

  • The rig mounted cyclone/cone splitter was levelled at the start of each hole to aid an even fall of the sample through the cyclone into the cone splitter.

  • RC drilling sample submissions include the use of certified standards (CRMs), and field duplicates were added to the submitted sample sequence to test laboratory equipment calibrations. Standards selected are matched to the analytical method of photon assaying at ALS labs in Perth (~500g units). No composites were taken.

  • Based on statistical analysis of these results, there is no evidence to suggest the samples are not representative.

Drilling techniques
  • The RC drill rig was a Schramm C685 & T685 rig type with the capability to reach >500m depths with a rig-mounted cyclone/cone splitter using a face sample hammer bit of 5 1⁄2 – 6" size.

  • The booster was used to apply air to keep drill holes dry and reach deeper depths.

Drill sample recovery
  • RC sample recovery is visually assessed and recorded where significantly reduced. Negligible sample loss has been recorded.

  • RC samples were visually checked for recovery, moisture and contamination. A cyclone and cone splitter were used to provide a uniform sample, and these were routinely cleaned.

  • RC Sample recoveries are generally high. No significant sample loss has been recorded.

Logging
  • RC chip samples have been geologically logged on a per 1 metre process recording lithology, mineralisation, veining, alteration, and weathering.

  • Geological logging is considered appropriate for this style of deposit (metamorphosed orogenic gold). The entire length of all holes has been geologically logged.

  • RC drill logging was completed by Benz Mining staff and data entered into BNZ's MXDeposit digital data collection platform provided by Expedio.

  • All drill chips were collected into 20 compartment-trays for future reference and stored securely at Glenburgh camp.

Sub-sampling techniques and sample preparation
  • RC chips were cone split at the rig. Samples were generally dry.

  • A sample size of between 3 and 5 kg was collected. This size is considered appropriate, and representative of the material being sampled given the width and continuity of the intersections, and the grain size of the material being collected.

  • For the 1 metre samples, certified analytical standards (appropriate for photon assaying) and field duplicates were inserted at appropriate intervals at a rate equal to 1 in 20 and sent for analysis with the samples.

  • Sample preparation was undertaken at ALS Laboratory – Perth. Gold analysis utilised the photon assaying methodology where original samples are crushed to 90% better than -3mm with a sub-set 500g separated for non-destructive analysis.

  • Any sample reporting as having elevated > 1µSv readings during the preparation for photon assaying at ALS labs were flagged and were submitted for fire assay (Au-AA26) methodology at ALS labs in Perth as a quantifying check against the Photon assays.

Quality of assay data and laboratory test
  • PhotonAssay at ALS Perth: Samples submitted for PhotonAssay analysis were dried, crushed to achieve approximately 90% passing 3.15 mm, rotary split, and a nominal ~500 g sub-sample was collected (method codes CRU-32a and SPL-32a). The ~500 g sub-sample was analysed for gold using the PhotonAssay technique (method code Au-PA01), together with quality control samples including certified reference materials and field duplicates.

  • ALS PhotonAssay Analysis Technique: Developed by CSIRO in collaboration with Chrysos Corporation, PhotonAssay is a rapid, chemical-free alternative to conventional fire assay that uses high-energy X-rays. The technique is non-destructive and analyses a substantially larger sample mass than the standard 50 g fire assay. ALS has extensively tested and validated the PhotonAssay method, with results benchmarked against traditional fire assay.

  • Routine mutli-element analysis - four acid digest with ICP-MS finish (method code ME-MS61) and portable XRF (method code pXRF-NQ) has been completed down hole on a pulverize 500 g split to better than 85% passing 75um (method code PUL-32m) but this information does not form part of this report.

  • Laboratory QA/QC is maintained through the routine use of internal certified reference materials and blanks as part of standard in-house procedures. In addition, BNZ submitted an independent suite of certified reference materials (see above). These data are formally reviewed on a periodic basis.

Verification of sampling and assaying
  • Significant drill intersections are checked by the supervising personnel. The intersections are compared to recorded geology and neighbouring data and reviewed in Leapfrog and QGIS software.

  • No twinned holes have been drilled to date by Benz Mining, but, planned holes have tested the interpreted mineralised trends, verifying the geometry of the mineralised targets.

  • All logs were validated by the Project Geologist prior to being sent to the Database Administrator for import

  • No adjustments have been made to assay data apart from values below the detection limit which are assigned a value of half the detection limit (positive number)

Location of data points
  • Hole collar coordinates including RLs have been located by handheld GPS in the field during initial drill site preparation. Actual hole collars were collected by a DGPS system at the Glenburgh Gold Project.

  • The grid system used for the location of all drill holes is GDA94_MGA _Zone 50s.

  • Planned hole coordinates and final GPS coordinates are compared in QGIS and Leapfrog project files to ensure all targets have been tested as intended.

  • The drill string path is monitored as drilling progresses using downhole Axis Champ Gyro tool and compared against the planned drill path, adjustment to the drilling technique is requested as required to ensure the intended path is followed.

  • Readings were recorded at 30m intervals from surface to end of hole after Benz reviewed single shot verses EOH continuous surveying of the Axis Champ Gyro tool and noted >3 degrees variance in azimuth with hole depth. The single shots produce less variability and are used for hole trace reporting in the database.

  • Historical drill hole surveys and methods will be reviewed in preparation for any updates to MRE in the future.

Data spacing and distribution
  • BNZ's Glenburgh RC drilling has been designed to infill and extend mineralisation defined by historical drilling. Drill spacings are varied. Holes were generally angled between -65 degrees towards ~145 degrees.

  • The mineralised domains established for pre-BNZ Mineral Resource Estimates have sufficient continuity in both geology and grade to be considered appropriate for the Mineral Resource and Ore Reserve estimation procedures and classification applied under the 2012 JORC Code. Ongoing drilling will be sufficiently spaced for a reinterpretation based on BNZ's structural model.

  • No sample compositing of material from drilling has been applied during this drilling campaign.

Orientation of data in relation to geological structure
  • Drilling has primarily been undertaken perpendicular to the interpreted mineralised structures as stated above.

  • No orientation-based sampling bias has been identified – observed intercepts to date indicate the interpreted geology hosting mineralisation is robust.

Sample security
  • All samples were prepared in the field by Benz Mining staff and delivered by contracted couriers from the field site to the ALS laboratory in Perth directly.

  • Individual pre-numbered calco sample bags are placed in polywoven plastic bags (5 per bag) secured at the top with a cable tie. These bags are annotated with the company name and sample numbers, the bags are placed in larger bulker bags for transport to ALS labs in Perth, also labelled with corresponding company name, drill hole and sample identifiers.

  • Sample pulps are stored in a dry, secure location at Benz's Glenburgh camp.

Audits or reviews
  • Data is validated by Benz staff and Geolytic database consultants as it is entered into MXDeposit. Errors are returned to field staff for validation.

  • All drilled hole collars have been located with a DGPS.

  • There have been no audits undertaken.

 

Section 2 Reporting of Exploration Results

(Criteria listed in the preceding section also apply to this section)

Criteria Commentary
Mineral tenement and land tenure status
  • Glenburgh Gold Project is a group of 10 tenements and 2 applications. The majority of known gold deposits are located on Mining Lease M09/148.
  • The tenement is 100% owned by Benz Mining Limited.
  • The tenements are in good standing and no known impediments exist.
Exploration done by other parties
  • Since Helix Resources in 1994 and subsequent work by Gascoyne Resources, about 159,149 soil samples, 1,349 vacuum holes and 2,285 auger holes have been completed at Glenburgh.
  • 48 diamond holes, 398 RC holes, 6 air-core holes and 462 RAB holes have been drilled in the Glenburgh area to identify the distribution and evaluate the potential of the deposit.
  • Drilling to date has identified 10 high potential deposits in the Glenburgh area which are: Tuxedo, Icon, Apollo, Mustang, Shelby, Hurricane, Zone 102, Zone 126, NE3 and NE4 deposits.
Geology
  • Gold mineralisation at the Glenburgh deposit is hosted in Paleoproterozoic upper-amphibolite to granulite facies siliciclastic rocks of the Glenburgh Terrane, in the southern Gascoyne Province of Western Australia.

  • Gold was first discovered at the Glenburgh deposit in 1994 by Helix Resources during follow-up drilling of soil geochemical anomalies. Mineralisation occurs in shears within quartz + feldspar + biotite ± garnet gneiss, which contains discontinuous blocks or lenses of amphibolite and occasional thin magnetite-bearing metamorphics, probably derived from chemical sediments.

  • Higher-grade mineralisation appears to be directly related to silica flooding in the gneiss. This silica flooding may give rise to quartz 'veins' up to several metres thick, although scales of several centimetres to tens of centimetres are the norm. Neither the higher-grade silica lodes nor the more pervasive lower-grade mineralisation exhibits sharp or well-defined lithological contacts.

Drill hole Information
  • For this announcement, 28 new Reverse Circulation (RC) are being reported.

  • For earlier released results, see previous announcements by Gascoyne Resources and Spartan Resources.

Data aggregation methods
  • No material information has been excluded.

  • Bulk intercepts: A nominal 0.3g/t Au lower cut off has been applied to results including up to a 10m limit on internal dilution unless otherwise stated. Short high-grade composites > 1.5 gram metres are included, otherwise a minimum composite length of 2m is applied.

  • High grade: A nominal 0.5g/t Au lower cut off has been applied to results including up to a 5m limit on internal dilution unless otherwise stated. A minimum composite length of 2m is applied.

  • Higher grade Au intervals lying within broader zones of Au mineralisation are reported as included intervals.

  • No top cuts have been applied to reported intercepts.

  • No metal equivalent values have been used.

  • All reported assays have been length weighted if appropriate.

  • Some drill holes reported in this announcement were previously disclosed based on partial assay results. Completion of outstanding assays has resulted in updated intercepts now being reported.

Relationship between mineralisation widths and intercept lengths
  • Drilling is generally oriented perpendicular to the interpreted strike of mineralisation, and intercepts are reported as downhole lengths unless otherwise stated.

  • To improve understanding of true widths, a subset of holes in this program were drilled from the opposite azimuth to previous drilling to test structural geometry. Ongoing drilling and geological modelling are required to confirm the true orientation and extent of mineralised lenses.

Diagrams
  • Relevant diagrams are included in the report.
Balanced reporting
  • All meaningful data relating to the Exploration program has been included and reported to the market as assays are received.
Other substantive exploration data
  • See body of announcement.
Further work
  • Assays for the remainder of the programme will be reported once received and validated.

  • Ongoing drilling across the Glenburgh camp to extend mineralisation along strike and at depth.
