Where is the Tolmer discovery located?

Tolmer is part of the Tarcoola gold project in South Australia, an area historically known for precious metals.

What makes Tolmer significant?

It hosts both silver and gold in high grades, making it a dualâcommodity exploration target.

What’s next for Barton Gold?

The company plans diamond drilling to uncover the source and controls of mineralisation, shaping the path for future development.

Growing Silver and Gold Horizons

The Tolmer discovery initially attracted interest due to exceptionally high silver content, ranking among the top global intersections earlier this year. Now, fresh drilling results have confirmed the presence of substantial gold alongside the silver, adding another dimension to the site’s value.

The company’s latest program has revealed that high‑grade gold exists not only in shallow oxide zones but also within deeper fresh rock layers. These intersections extend the previously known mineralised horizons, showing that silver and gold occur together in multiple layers. This overlap increases the strategic interest of the project, as both metals could potentially be developed in tandem.

Mapping a Larger Mineralised System

Drilling and sampling suggest the mineralised footprint at Tolmer covers a wide area, with enrichment zones stretching across more than a kilometre. The presence of high‑grade gold within these zones points to a more complex and extensive mineral system than originally anticipated.

Barton Gold is undertaking structural analysis to understand how the mineralisation formed and where additional high‑grade zones might be located. This understanding will help refine future exploration and drilling priorities.

Next Steps in Exploration

With diamond drilling scheduled to commence shortly, Barton Gold aims to investigate the geological structures controlling mineralisation at Tolmer. These efforts are expected to help identify new drill targets and potentially link different mineralised zones into a coherent deposit model.

Sampling programs have also been completed over a broader area surrounding the original discovery, and results from these are awaited. The findings will guide the next stages of exploration and could significantly influence how the project evolves.
