Benz Mining has unveiled a maiden Exploration Target for its Glenburgh Gold Project, estimating up to 12 million ounces of gold largely defined by drilling. The project’s scale and geological setting support ambitions for a world-class gold system, with aggressive drilling planned to convert the target into a Mineral Resource by 2027.
- Maiden Glenburgh Exploration Target estimates 10.1–12.0 Moz gold
- Approximately 80% of target drill-defined and assay-supported
- Target includes higher-grade core and broader mineralised halo
- Aggressive drilling and metallurgical work planned over 12 months
- Entire target within fully permitted mining lease enabling rapid development
Glenburgh Emerges as Major Gold System with Multi-Million-Ounce Potential
Benz Mining Corp (ASX:BNZ, TSXV: BZ) has defined a maiden Exploration Target for its 100%-owned Glenburgh Gold Project in Western Australia’s Gascoyne region, estimating between 10.1 and 12.0 million ounces of gold within 485 to 540 million tonnes at grades of 0.6 to 0.7 g/t Au. This initial target frames Glenburgh as an emerging major gold system with the scale and geological architecture to support a world-class project.
Notably, about 80% of the Exploration Target is drill-defined, assay-supported, and wireframed, underpinning a robust technical foundation. The remaining 20% reflects conceptual geological projections beyond the current drill footprint, highlighting significant upside potential. The target comprises a higher-grade core (110–125 Mt at 1.7–1.8 g/t Au containing 6.1–7.3 Moz) surrounded by a lower-grade mineralised halo (375–415 Mt at 0.33–0.35 g/t Au containing 4.0–4.6 Moz).
Drilling and Metallurgical Work to Accelerate Resource Definition
Over the next 12 months, Benz plans aggressive infill, extensional, and down-plunge drilling to test and expand the target, aiming to convert a substantial portion into a Mineral Resource during calendar year 2027. Complementary metallurgical testwork will build on earlier results from the Icon deposit, which demonstrated gold recoveries of up to 93.3% from lower-grade halo material, supporting its potential contribution to future mining inventory.
The entire Exploration Target lies within Benz’s wholly owned, granted, and fully permitted Mining Lease, providing a clear and rapid pathway to development once a maiden Mineral Resource is defined. CEO Mark Lynch-Staunton emphasised that Glenburgh’s scale and geological setting offer the potential to evolve into a world-class gold system, with Benz well funded following a $75 million capital raise earlier this year to execute the program at pace.
Technical Foundation Based on Extensive Historical and Recent Drilling
The Exploration Target is based on data from approximately 1,100 drill holes (diamond and reverse-circulation) totalling around 200,000 metres, including Benz’s drilling and that of prior explorers. The drill-constrained component, representing around 80% of the target, is supported by wireframe modelling and assay data. Conceptual projections beyond current drilling have been conservatively included at varying rates depending on the camp, with 20% applied at Icon and Hurricane and 80% at Thunderbolt, reflecting its shallow and under-tested nature.
Grade estimation employed both top-cut, spatially declustered composites for conservative lower bounds and raw data for upper bounds, separating higher-grade and lower-grade domains by camp-specific thresholds. Tonnage estimates include a ±10% range to reflect the conceptual nature of the target. Bulk densities were applied based on drill core measurements.
Glenburgh’s Geological Setting and Strategic Position
Glenburgh’s geology features metamorphosed pelitic sediments and mafic volcanic rocks altered during the Paleoproterozoic Glenburgh Orogeny, hosting a substantial sea floor alteration system associated with gold mineralisation. The deposit’s core includes folded metapelitic rocks with silica-rich chert bands, iron formations, and tungsten-rich layers, contributing to its complex mineralogy and encouraging metallurgical recoveries.
The project’s 18–20 kilometre mineralised corridor encompasses multiple camps, Icon, Hurricane, and Thunderbolt, each offering distinct mineralisation styles and growth prospects. The combination of thick, bulk-style mineralisation and high-grade underground lenses presents a rare development opportunity in the Australian gold sector.
Next Steps and Exploration Outlook
Benz’s immediate focus is on infill drilling to tighten drill spacing to approximately 25m by 25m, extensional drilling to test conceptual projections, further metallurgical testwork, and updated geological modelling to support a Mineral Resource estimate. The company’s approach reflects confidence in Glenburgh’s potential while acknowledging the Exploration Target remains conceptual, with conversion contingent on future drilling and studies.
With a strong balance sheet and a fully permitted mining lease, Benz is positioned to advance Glenburgh rapidly, potentially unlocking a new major gold district in Western Australia. How aggressively the company can convert this target into a defined resource and the economics of incorporating the broader mineralised halo into mining plans will be key factors to watch.
Bottom Line?
Benz’s maiden Exploration Target at Glenburgh lays a solid foundation, but converting conceptual ounces into a resource will require sustained drilling and validation in the year ahead.
Questions in the middle?
- How will ongoing drilling refine the balance between higher-grade core and mineralised halo?
- What impact will tungsten mineralisation have on Glenburgh’s economic potential?
- Can metallurgical performance maintain high gold recoveries across the broader system?
