Buxton Resources Uncovers New Silver-Lead-Zinc Prospect at Zanthus Project

4 min read | July 06, 2026 12:53 AM AEST | By Aditi Sarkar

Buxton Resources Ltd has revealed a notable silver-lead-zinc prospect at its Zanthus Project located in the Fraser Range, Western Australia. This discovery follows an extensive reevaluation of past data and the restoration of full ownership of the project to Buxton. Market participants are eagerly anticipating the forthcoming ground electromagnetic survey designed to better delineate the mineralisation potential.<\/p> <\/div>

Key Points<\/h3>
  • Buxton Resources Ltd (ASX:BUX)<\/li>
  • Discovery of a Broken Hill\/Cannington-style silver-lead-zinc target at the Cohen prospect<\/li>
  • Top assay result: 2.0 m at 7.5 g\/t Ag, 1,405 ppm Pb, and 4,230 ppm Zn<\/li>
  • Ground electromagnetic survey set to begin in July 2026<\/li> <\/ul> <\/div>

    Buxton Regains Full Control of Zanthus Project<\/h2>

    Following IGO Ltd’s withdrawal from their Farm-In and Joint Venture agreement, Buxton Resources Ltd has reclaimed 100% ownership of the Zanthus Project. This change has enabled the company to undertake a thorough internal review of historical data, culminating in the identification of a promising silver-lead-zinc target at the Cohen prospect.<\/p>

    Located in Western Australia’s Fraser Range, the Zanthus Project is now completely under Buxton’s control, allowing for unfettered exploration and development efforts.<\/p>

    Identification of Significant Silver-Lead-Zinc Target<\/h2>

    New assay and mineralogical analyses have revealed a Broken Hill\/Cannington-style silver-lead-zinc target within the Cohen prospect, positioned in the same stratigraphic sequence that hosts Buxton’s historic magnetite mineralisation.<\/p>

    The standout assay from recent drilling recorded an interval of 2.0 meters grading 7.5 grams per tonne silver, 1,405 parts per million lead, and 4,230 parts per million zinc between 220 and 222 meters in hole ZRC025. Mineralisation remains open at depth, indicating potential for further resource expansion.<\/p>

    Ground Electromagnetic Survey Scheduled<\/h2>

    Buxton Resources has contracted a specialist to perform a ground electromagnetic (EM) survey at the Cohen prospect, focusing on detecting concealed sulphide conductors. This survey is planned to commence in July 2026 and aims to identify precise drill targets.<\/p>

    Integrating existing geophysical datasets with recent drilling results, the survey will provide a comprehensive framework to define the mineralisation’s extent. Outcomes will inform subsequent drilling programs.<\/p>

    Re-assay of Historical Samples Validates Anomalies<\/h2>

    Utilising an enhanced geochemical technique, Buxton re-assayed historical pulps from drill holes ZRC024 and ZRC025. This confirmed a consistent silver-lead-zinc-cadmium-manganese anomaly at the base of hole ZRC025, directly beneath a manganese-rich magnetite-quartzite layer.<\/p>

    The geochemical and mineralogical signatures of this zone align with those of globally recognised Broken Hill-type deposits, highlighting significant exploration potential.<\/p>

    Strategic Location with Infrastructure Advantages<\/h2>

    The Zanthus Project lies within the Proterozoic Albany-Fraser Orogen of southern Western Australia, a region known for hosting Broken Hill-style mineralisation. Its proximity to the Trans-Australian Rail Line offers access to multi-user rail infrastructure, facilitating efficient logistics.<\/p>

    Vehicular access is available via the Trans Access Road from Kalgoorlie, ensuring smooth operations for exploration and development activities.<\/p>

    Planned Exploration Activities<\/h2>

    Buxton Resources intends to proceed with the ground EM survey as planned and will release results following completion of data processing and interpretation. The company remains focused on advancing the Zanthus Project to realise its full mineral potential.<\/p>

    Investors are encouraged to follow updates as the exploration program advances and new information emerges.<\/p>

    Market and Investor Outlook<\/h2>

    The discovery of a significant silver-lead-zinc target at Zanthus represents a positive milestone for Buxton Resources, potentially enhancing its resource inventory and market valuation. The immediate impact on the share price has not been disclosed publicly.<\/p>

    Investors may view the company’s proactive exploration strategy and focus on high-potential mineral systems favorably. The results of the upcoming ground EM survey will be pivotal in shaping the project’s future direction.<\/p>

    Management Commentary on Project Progress<\/h2>

    Marty Moloney, Managing Director of Buxton Resources, expressed optimism regarding the Zanthus Project following the identification of the silver-lead-zinc target. The company is expediting the ground EM survey to define drill targets promptly.<\/p>

    Moloney emphasized the significance of the mineral system, drawing parallels with world-class deposits such as Broken Hill and Cannington. The company’s commitment to detailed geological analysis and re-assaying of legacy data reflects its dedication to maximising project value.<\/p>
