HIGHLIGHTS

Tolmer high-grade silver discovery: expedited soil geochemistry program completed over ~1.9km²area surrounding recently expanded reverse circulation (RC) drilling program¹

ADELAIDE, AUSTRALIA / ACCESS Newswire / July 13, 2025 / Barton Gold Holdings Limited (ASX:BGD)(FRA:BGD3)(OTCQB:BGDFF) (Barton or Company) is pleased to confirm that an expedited soil sampling program has been completed over a ~1.9km² area surrounding the new 'Tolmer' high grade silver discovery at the Company's South Australian Tarcoola Gold Project (Tarcoola). ~380 samples have been collected with assay results expected during September 2025.¹ Expedited Tolmer Soil Sampling Tests ~1.9km2 Footprint

Commenting on the geochemical program, Barton Managing Director Alexander Scanlon said:

"We recently expanded our Tolmer ‘silver zone' drilling by ~50% to cover a ~400 metre by ~250 metre area based, in part, upon further geological surface reconnaissance. This program extends that reconnaissance to a broader area of ~1,700 metres by ~1,100 metres to see if we can potentially identify a larger mineralised footprint."

Program background

Barton identified Tolmer as a high-grade gold discovery in August 2024, and subsequently identified a new ‘silver zone' ~500m west in a line of seven discovery holes with globally significant assays including 6m @ 4,747 g/t Ag from 46m, 14m @ 434 g/t Ag from 46m and 4m @ 1,417 g/t Ag from 9m.²

2,882m RC drilling was completed during June 2025 to test extensions of mineralisation in all directions, with the current geochemical sampling intended to potentially map a broader surface footprint.³
