Diamond Drilling Begins at Tolmer Discovery

HIGHLIGHTS

  • March 2025 Tolmer discovery hole ranked 5th highest-grade silver intersection reported globally during H1 2025, with an interval of 6m @ 4,747 g/t Ag from only 46m depth1

  • New assays have extended high grade silver horizons, and added coincident high-grade gold up to ~13g/t Au, within a highly mineralised footprint now ~1.5km wide2

ADELAIDE, AUSTRALIA / ACCESS Newswire / August 10, 2025 / Barton Gold Holdings Limited (ASX:BGD)(FRA:BGD3)(OTCQB:BGDFF) (Barton or Company) is pleased to confirm diamond drilling (DD) has commenced at the Tolmer prospect, located at the Company’s South Australian Tarcoola Gold Project (Tarcoola). An initial program of 3 holes totalling ~550 metres drilling is planned in the ‘eastern gold zone’ to investigate local structural controls and guide future targeting.

Full details are contained in the complete announcement, which can be accessed on the ASX website, the investor section of Barton’s website, or directly by clicking here.

Commenting on the Tolmer diamond drilling, Barton Managing Director Alexander Scanlon said:

“Tolmer is an exciting new discovery located between our existing Central Gawler Mill and planned Tunkillia mill. With gold and silver grades up to 83.6g/t Au and 17,600g/t Ag, Tolmer has clear potential to add significant value to our regional development strategy. This diamond drilling will help improve our local structural knowledge as we work to identify the origins of such high-grade mineralisation.”
