Completion of Diamond Drilling on High Grade Tolmer Prospect
Barton Gold Holdings (OTCQB:BGDFF) has completed diamond drilling at its high-grade Tolmer gold and silver prospect within the South Australian Tarcoola Gold Project. The program consisted of three holes totaling 595.3 metres in the 'eastern gold zone' to identify structural controls for future targeting.
The Tolmer prospect has yielded exceptional results, with the March 2025 discovery hole ranking as the 5th highest-grade silver intersection globally in H1 2025, featuring 6m @ 4,747 g/t Ag from 46m depth. The mineralized footprint has expanded to ~1.5km wide, with impressive grades reaching up to 83.6g/t Au and 17,600g/t Ag. Recent RC drilling has extended silver mineralization and added high-grade gold in the 'western silver zone'.
A soil sampling program covering ~1.9km² was completed in July 2025, with approximately 430 samples collected and assays expected in September 2025.
Barton Gold Holdings (OTCQB:BGDFF) ha completato perforazioni diamantate al suo prospetto ad alto tenore di Tolmer, parte del Tarcoola Gold Project nel Sud Australia. Il programma ha previsto tre fori per un totale di 595,3 metri nella «zona aurifera orientale» per individuare i controlli strutturali utili al targeting futuro.
Il prospetto Tolmer ha restituito risultati eccezionali: il foro di scoperta di marzo 2025 è classificato come il 5° intervallo argenteo a più alto tenore a livello mondiale nella prima metà del 2025, con 6 m @ 4.747 g/t Ag a partire da 46 m di profondità. L’impronta mineralizzata si è estesa fino a circa 1,5 km di larghezza, con tenori di rilievo che arrivano fino a 83,6 g/t Au e 17.600 g/t Ag.

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 24, 2025 / Barton Gold Holdings Limited (ASX:BGD)(FRA:BGD3)(OTCQB:BGDFF) (Barton or Company) is pleased to confirm the completion of diamond drilling (DD) at the high-grade Tolmer gold and silver prospect, located at the Company's South Australian Tarcoola Gold Project (Tarcoola). Three holes totalling 595.3 metres drilling were completed in the 'eastern gold zone' to identify structural controls and guide future targeting.
Commenting on the Tolmer diamond drilling, Barton Managing Director Alexander Scanlon said:
"Tolmer is an exciting new discovery near our Central Gawler Mill, with shallow gold and silver up to 83.6g/t Au and 17,600g/t Ag. This initial round of diamond drilling will give us a helpful 'first look' at local structural controls and, together with the pending results of soil assays over the whole area, will help guide future targeting across a now 1.5km wide footprint of shallow, high-grade mineralisation. We look forward to sharing further updates."

Program background
During August 2024 Barton announced a Tolmer high-grade gold discovery and then, during March 2025, Barton announced one of Australia's highest-grade modern silver discoveries ~500m further west.3 These neighbouring 'eastern gold zone' and 'western silver zone' discoveries have yielded grades up to 83.6g/t Au and 17,600g/t Ag, respectively, with high-grade gold and silver present in each zone.3
Recent RC drilling assays extended broad silver mineralisation and also added high-grade gold to the 'western silver zone' (see Table 1), yielding a highly enriched mineralised footprint ~1.5km wide.4 While silver up to 117g/t Ag was encountered in fresh rock in this drilling, the origin of this high-grade mineralisation has not yet been confirmed, and is a key focus of ongoing investigation.

Multiple horizons of broad, shallow high-grade Au-Ag mineralisation
Recent RC drilling in Tolmer's 'western silver zone' have infilled and extended an 'upper horizon' of shallow, broad 'silver dominant' mineralisation (largely independent of gold) to the west, while adding additional high-grade gold and silver intervals to a much higher-grade 'lower horizon' with silver up to 17,600g/t Ag.5
Recent drilling also identified a potential southern extension of the 'lower horizon' containing both high grade gold and silver (see Figure 4), as well as silver intersections up to 117g/t Ag in the underlying fresh rock.5 The goal of new diamond drilling is to identify local structural controls to guide future drill targeting.

Soil sampling program also underway
In July 2025 Barton completed a soil sampling program over a ~1.9km2 area surrounding the 'Tolmer' high grade silver and gold discoveries, collecting ~430 samples with assays expected during September 2025.6
