Testing regional exploration targets in ‘Stage 1' development area

HIGHLIGHTS

• Soil sampling recently completed over ~1.9km² surrounding Tolmer high-grade silver discovery^[1]

• Additional ~23km² program completed at ‘Black Oak Tank' prospect (Tarcoola Gold Project)

• Additional ~6km² program completed at ‘308' prospect ~20km northeast of Central Gawler Mill

• Tolmer, Black Oak Tank and 308 soil assay results expected during September & October 2025

ADELAIDE, AUSTRALIA / ACCESS Newswire / July 16, 2025 / Barton Gold Holdings Limited (ASX:BGD)(FRA:BGD3)(OTCQB:BGDFF) (Barton or Company) is pleased to confirm that the further soil geochemistry programs have been completed on two key regional targets.

The ‘Black Oak Tank' prospect is located on the northern margin of the Lake Labyrinth Shear Zone, on Exploration Licence (EL) 6210 at the Company's South Australian Tarcoola Gold Project (Tarcoola).

The ‘308' prospect is located to the northeast of the Company's Central Gawler Mill, on EL 6502, at the Company's South Australian Challenger Gold Project (Challenger).

A total of 501 samples (including duplicates) have been collected at Black Oak Tank and 308 over a combined area of ~29km ², with assay results expected to be received during October 2025.

These programs follow the expedited soil geochemistry program recently completed at Barton's ‘Tolmer' high grade silver discovery, located at the Company's South Australian Tarcoola Gold Project (Tarcoola). ^[2] That program covered ~1.9km ² surrounding an expanded June 2025 drilling program totalling ~2,900m. ² Assay results for Tolmer drilling and soil samples are expected in July and September 2025, respectively.

Commenting on the geochemical programs, Barton Managing Director Alexander Scanlon said:
"With the core platforms now established for our planned ‘Stage 1' operations at the Central Gawler Mill, and a subsequent ‘Stage 2' expansion at Tunkillia, Barton will advance those projects in parallel while remaining focused on opportunities to more fully leverage that existing and planned future infrastructure in the future.

"Our unique regional infrastructure and operating platform provides multiple advantages in testing exploration targets and progressing development prospects. As this regional platform grows, we can play an increasingly active role in unlocking and accelerating value in previously isolated regional assets.

"Our recent Tolmer high-grade gold and silver discoveries, and our proposed acquisition of Cobra Resources' Wudinna Gold Project, are strong examples of complementary exploration and development initiatives. These offers significant optionality to our ‘Stage 1' Central Gawler Mill and planned ‘Stage 2' Tunkillia mill, respectively."

Program details
The Black Oak Tank program comprised 416 samples (including duplicates) collected at ~500m spacing, over an area of ~23km ² in size. Black Oak Tank is located along the Lake Labyrinth Shear Zone, northwest of Indiana Resources (ASX:IDA) Minos gold project, in an area with little historical exploration investment.

The 308 prospect program comprised 85 samples (including duplicates) collected over an area of ~6km ² in size. The 308 prospect is located ~20km northeast of Barton's Central Gawler Mill on EL6502, also in an area with relatively little historical exploration investment despite its proximity to the Central Gawler Mill.
