Barton Gold Holdings Limited (ASX:BGD, FRA:BGD3, OTCQB:BGDFF) has received a ~$520,000 research and development (R&D) cash tax refund for the year ended 30 June 2025 under the Federal Government's R&D Tax Incentive Program. This refund has contributed to the significant acceleration of Barton's exploration activity and efficiency in an emerging gold province. Barton has executed a range of R&D work programmes during fiscal year 2025, including trialling multiple technologies to develop new methodologies for exploration under cover in South Australia, and the development of new regional geological models. These work programmes have been completed in the vicinity of the company's Tarcoola and Tunkillia Gold Projects. Several of these work programs remain ongoing and are expected to be completed during the 2026 and 2027 financial years. The R&D Tax Incentive Program has directly contributed to significant technical outcomes, including the testing of a new regional structural model for the Tarcoola Goldfield, new predictive models for alteration zones on the Yarlbrinda Shear Zone (which hosts the Tunkillia project), and the validation of multiple predicted structures and alteration zones. These outcomes have resulted in the targeting and identification of Barton's dual Tolmer gold and silver discoveries during 2024 and 2025, with gold and silver grades up to 17,600g/t Ag and 83.6g/t Au.
