Barton Gold Unveils Striking High-Grade Silver and Gold at Tolmer Discovery

Tolmer Discovery Breaks New Ground

Barton Gold Holdings Limited (ASX, BGD) has delivered a compelling update from its Tolmer discovery within the Tarcoola Gold Project in South Australia. The latest reverse circulation drilling assays have unveiled remarkably high-grade silver and gold mineralisation, with silver assays reaching as high as 2,240 grams per tonne (g/t) and gold up to 51.2 g/t. These results not only extend the known silver mineralisation but also reveal significant gold intervals alongside silver, adding a new dimension to the project’s potential.

Multiple Mineralisation Horizons Identified

The drilling program, comprising 2,882 metres of reverse circulation drilling, has delineated multiple horizons of mineralisation. An upper horizon features broad, shallow silver mineralisation averaging around 100 g/t in the oxide zone, largely independent of gold. Beneath this lies a lower horizon characterized by very high-grade silver ranging from approximately 200 to 4,750 g/t, now confirmed to also host broad intervals of high-grade gold. This dual presence of gold and silver within the same horizons is a notable development, suggesting a complex and enriched mineral system.

Expanding the Mineralised Footprint

The Tolmer mineralised zone now spans more than 1.5 kilometres in width, a significant footprint for a high-grade silver-gold discovery in Australia. The recent drilling has infilled and extended the original discovery line, with new drill lines indicating possible east-west orientation of mineralisation in the oxide and weathered zones. This spatial understanding is crucial as Barton Gold prepares to undertake diamond drilling aimed at deciphering the structural controls that govern the mineralisation.

Next Steps, Diamond Drilling and Soil Sampling

Complementing the drilling results, Barton Gold recently completed a soil sampling program over a 1.9-kilometre area surrounding the Tolmer discovery, with assay results expected in September 2025. The forthcoming diamond drilling program will provide detailed structural insights and help guide future exploration efforts. Managing Director Alexander Scanlon highlighted the excitement around the emerging gold alongside silver, underscoring the potential for a richer and more complex deposit than initially anticipated.

Strategic Implications for Barton Gold

These assay results reinforce Barton Gold’s position as a significant player in the South Australian gold and silver exploration space. The Tolmer discovery’s high grades and expanding footprint could materially enhance the company’s resource base and future production profile. With a portfolio that includes the fully permitted Central Gawler Mill and other projects, Barton is well positioned to leverage these findings into development opportunities.
