Barton Gold Holdings Ltd. has commenced diamond drilling at the Tolmer prospect, part of its Tarcoola Gold Project in South Australia. The project aims to explore the promising new discovery located between the existing Central Gawler Mill and the planned Tunkillia mill. The discovery has shown gold and silver grades reaching up to 83.6g/t Au and 17,600g/t Ag, highlighting its potential to significantly enhance Barton's regional development strategy. The initial drilling program consists of three holes, totalling approximately 550 meters, focused on the 'eastern gold zone' to better understand local structural controls and guide future exploration efforts. The Tolmer discovery ranked as the 5th highest-grade silver intersection globally in the first half of 2025, with assays extending high-grade silver horizons and revealing coincident high-grade gold within a mineralized footprint about 1.5 kilometers wide.
