Haul road and access infrastructure are vital for efficient ore transport from mine to processing and export, representing tangible progress toward operational readiness.

AusPozz™ Commercial-Scale Production Trials Commence with 800 Tonnes of Toondoon Kaolin Dispatched

Zeotech has advanced its AusPozz™ product to commercial-scale production trials, a key milestone in commercialising its high-reactivity metakaolin technology. Approximately 800 tonnes of kaolin feedstock from Toondoon have been prepared and dispatched to support these trials. This feedstock, primarily sourced from a test pit completed in December 2025, provides a commercially representative sample for downstream processing, product validation, and customer qualification. AusPozz™ is positioned as a low-carbon supplementary cementitious material ("SCM") for concrete applications, targeting the construction market’s demand for carbon reduction and enhanced performance.

Strong early commercial demand is reflected by 80% of AusPozz™ production from the trial already committed to a key development partner. The remaining 20% is being evaluated through multiple commercial concrete trial opportunities to broaden product validation across various applications and markets. Prior to this, Zeotech completed pilot-scale calcination testing with a leading Australian technology provider, generating essential data on material behavior, conversion efficiency, and reactivity to support scale-up and process design.

Concrete Performance Trials Highlight Superior Strength in Slab-on-Ground Applications

Zeotech conducted concrete performance tests focusing on slab-on-ground applications, a major segment of the Australian concrete market including residential slabs, driveways, footpaths, and light commercial floors. These applications typically require strengths between 20 MPa and 32 MPa. The trials assessed AusPozz™ as a partial replacement for conventional supplementary cementitious materials like fly ash within a 240 kg total cementitious content ("TCC") mix.

Results showed significant improvements in Unconfined Compressive Strength ("UCS") compared to fly ash mixes: AusPozz™ achieved 21 MPa at 7 days versus 16 MPa for fly ash, and 42 MPa at 28 days versus 26 MPa. These strength gains support faster construction schedules and improved durability without compromising workability, indicating AusPozz™ can replace fly ash without altering mixing or placement processes—an important advantage for market adoption.

Major Infrastructure Trials in Victoria Validate AusPozz™ for Large-Scale Civil Projects

Alongside slab-on-ground testing, Zeotech progressed concrete trials linked to major infrastructure projects in Victoria with leading industry partners. These trials assessed AusPozz™ performance in large-scale civil construction, focusing on durability, strength development, and carbon reduction under real project conditions. Successful outcomes position AusPozz™ for specification in future infrastructure projects and build credibility with contractors and developers.

This aligns with Zeotech’s commercialisation strategy to establish a scalable, low-carbon, high-performance SCM. Success in Victoria could generate reference projects valuable for marketing to state and federal procurement bodies, especially as sustainability criteria become integral to public infrastructure.
