Anglo Saxon Gold Resource Hits 206,000 Ounces at 4.06 g/t in Latest Estimate
Hawthorn Resources has released an updated Mineral Resource Estimate for its Anglo Saxon Gold Project in Western Australia, reinforcing the project's potential for open pit mining amid record gold prices. The new data brings the project closer to production with significant ounces confirmed.
- Updated Mineral Resource Estimate reports 1.53 million tonnes at 4.06 g/t gold (cut) for 206,326 ounces at 0.5 g/t cut-off
- Higher-grade underground potential of 709,016 tonnes at 6.64 g/t gold for 151,359 ounces at 3.0 g/t cut-off
- Resource classified as Indicated and Inferred, supporting both open pit and underground mining scenarios
- MineComp commissioned for open pit optimisation study using updated resource and current cost inputs
- Joint Venture well capitalised and preparing for mining development agreement negotiations
Context and Location
Hawthorn Resources Limited (ASX – HAW) has taken a significant step forward with its Anglo Saxon Gold Project, located near Pinjin in Western Australia, approximately 140 kilometres northeast of Kalgoorlie. The project sits within the Trouser Legs Joint Venture, where Hawthorn holds a 70% stake alongside Gel Resources Pty Ltd. This region is part of the Laverton Tectonic Zone, a prolific gold belt with a combined endowment exceeding 30 million ounces.
Updated Mineral Resource Estimate
The recently completed Mineral Resource Estimate (MRE), prepared by BM Geological Services, incorporates data from a substantial 7,846-metre infill reverse circulation drilling program conducted in 2025. The updated resource outlines 1.53 million tonnes at a cut gold grade of 4.06 grams per tonne, equating to approximately 206,326 ounces at a 0.5 g/t cut-off grade, which aligns with potential open pit mining methods. At a higher cut-off of 3.0 g/t, more indicative of underground mining, the resource stands at 709,016 tonnes grading 6.64 g/t gold for 151,359 ounces.
Technical Approach and Classification
The resource estimation employed Ordinary Kriging techniques, with detailed geological modelling based on narrow, stacked quartz veins within a shear zone. The mineralisation remains open at depth, extending beyond 310 vertical metres, suggesting further upside potential. The resource is classified into Indicated and Inferred categories, reflecting confidence levels based on drill spacing and geological continuity. Notably, the Indicated portion benefits from drill spacing of approximately 10 by 20 metres and includes diamond drilling data, enhancing reliability.
Advancing Towards Production
Following the resource update, the Joint Venture has engaged MineComp Pty Ltd to conduct an open pit optimisation study, integrating the updated resource model with current cost and gold price inputs. This study will inform the economic viability and mine design parameters for the next phase of development. Concurrently, Hawthorn is preparing to enter negotiations with third parties for mining development agreements, signalling a clear intent to progress towards production.
Financial Position and Market Context
Hawthorn confirms it remains well capitalised to fund the forthcoming stages of project development. This financial strength positions the company to capitalise on the current record gold price environment, which enhances the project's economic prospects. The Anglo Saxon deposit's history of producing approximately 50,000 ounces between 2017 and 2019 via third-party toll treatment further underpins its operational potential.
Outlook and Considerations
While the updated MRE significantly de-risks the Anglo Saxon project, some uncertainties remain, particularly regarding bulk density data and the geological continuity of narrow veins. Hawthorn has recommended further QAQC improvements and density measurements to refine future resource estimates. The forthcoming open pit optimisation results and mining agreement negotiations will be critical milestones to watch as the project advances.
Bottom Line?
With a robust updated resource and strategic studies underway, Anglo Saxon is poised to transition from exploration to production, but key optimisation outcomes will shape its near-term trajectory.
Questions in the middle?
- How will the open pit optimisation study influence the mine plan and project economics?
- What are the timelines and terms expected for the mining development agreements with third parties?
- How might further drilling or density data collection impact resource confidence and classification?
