Dear Investors & Colleagues, We are proud to share today our 31 December 2023Quarterly Activities ReportandCashflow Report, which highlight some major accomplishments to close out 2023 and a fast start to 2024. In addition to more than 400,000oz Au growth at our Tunkillia project during 2023, we also have another ~9,000m of RC and diamond drilling samples already in the lab for 2024. These samples are from multiple growth and discovery targets at Tarcoola and Tunkillia, and keep Barton on pace for much more news - and potentially additional JORC Resources growth - in the near future. In parallel, we are now planning to drill test priority targets from our new Tarcoola structural model, where new discoveries could support potential future Stage 1 operations utilising our Central Gawler Mill. Finally, with$4.6m cash at 31 December 2023 and $4.3m contained gold in concentrates (~1,400oz Au) now for sale, Barton is in an exceptionally strong position to continue its pursuit of cost-efficient growth in South Australia. We look forward to sharing a steady flow of interesting exploration, project and corporate updates to you all during the coming months. Regards, Alex Scanlon MD & CEO
