Barton Gold Holdings Limited: Tarcoola Gold Project Exciting Development Prospect
Barton Gold Holdings Limited (ASX: BGD), a gold developer, has announced exciting new assay results from the Tolmer prospect at its South Australian Tarcoola Gold Project. The results confirm high-grade silver and gold mineralization in two distinct zones, with assay grades up to 17,600g/t Ag and 83.6g/t Au. Tolmer is considered an exciting development prospect, with two shallow high-grade silver and gold zones emerging next to each other. The “eastern gold” zone has been extended 100 meters north, and the “western silver” zone appears to thicken and carry high-grade silver as it continues west. The best new silver intersection is only 25 meters west of the company’s best silver result to date, which was 6m @ 4,747g/t Ag. The assay results published on March 27, 2025, for Tolmer’s “silver zone” indicate a distinct “silver dominant” mineralization in association with a broad zone of anomalous lead, where high-grade silver occurs largely independent of gold. The latest assays support this interpretation, with new intersections infilling and extending broad and high-grade silver mineralization to the west within interpreted oxide and transitional zones. The “western silver” zone has been identified as a shallow and broadening zone, with new significant assays including a 2m @ 111g/t Ag intersection from TBM225, a 4m @ 1,417g/t Ag intersection from TBM227, and a 23m @ 95g/t Ag intersection from TBM228. The “eastern gold” zone has been extended 100 meters north, with significant assays including a 5m @ 3.07g/t Au intersection from TBM221 and a 5m @ 4.38g/t Au intersection from TBM222. Barton MD Alexander Scanlon said, “Tolmer is fast becoming an exciting development prospect, with two shallow high-grade silver and gold zones emerging next to one another. Also of interest, the best new silver intersection is only 25 meters west of our best silver result to-date of 6m @ 4,747g/t Ag, and includes two intervals of high-grade gold over 3g/t Au.”
The company is planning an expedited follow-up drilling program to map and drill test the potential western, northern, and southern extensions of the “silver zone”. This program will include the use of Barton’s proven methodology for the application of Portable PPB’s detectORE TM technology, rapid in-field analyses, and RC drilling guided by real-time Portable PPB’s detectORE TM results. The Tolmer prospect is located approximately 5km west of Barton’s Perseverance Mine (Tarcoola) and approximately 130km southeast of the company’s fully permitted Central Gawler Mill. The location provides multiple potential future commercialization opportunities for blending of high-grade gold and silver mineralization into Barton’s existing Central Gawler Mill, or its future planned Tunkillia Mill. The company’s Competent Person, Mr. Marc Twining, has stated that the information in this announcement that relates to Exploration Results for the Tarcoola Gold Project is based upon, and fairly represents, information and supporting documentation compiled by Mr. Twining. The Tarcoola Gold Project has a strong geological setting, with the Archaean and Proterozoic rocks forming the basement to an extensive cover of Phanerozoic sediments. The deposit is hosted within sedimentary rocks of the Tarcoola Formation and granite, both of Proterozoic age. The granite is variably in fault contact with or unconformably overlain by the sediments, which consists of conglomerate, limestone, sandstone, siltstones, and shale. The company has a proven track record of using geoscientific data to identify high-grade gold and silver mineralization. The recent assay results demonstrate the effectiveness of this approach, with two distinct high-grade zones emerging next to each other. The Tarcoola Gold Project has significant potential for future gold production, with the company targeting annual production of 150,000oz. The project’s Mineral Resources have been estimated to be 909koz Au (30.8Mt @ 0.92g/t Au) in the Indicated category and 799koz Au (33.2Mt @ 0.75g/t Au) in the Inferred category.

The company’s management believes that the recent assay results demonstrate the potential for the Tolmer prospect to become an exciting development prospect, with two shallow high-grade silver and gold zones emerging next to each other. The company is planning to conduct further exploration and drilling work to map and drill test the potential western, northern, and southern extensions of the “silver zone”.
