Barton Gold Launches Diamond Drilling Program at Promising Tolmer Silver Prospect
Barton Gold Holdings (ASX:BGD) (OTCQB: BGDFF) is seeking to obtain a deeper understanding of the promising precious metal opportunity at the Tolmer prospect with diamond drilling (DD) now underway at its Tarcoola gold project in South Australia.
The initial Tolmer discovery returned a silver intersection of 6 metres at 4,747 grams per tonne, the fifth-highest grade silver intersection reported globally during the first six months of 2025.
Subsequent exploration work and drilling has confirmed the silver potential there as well as the high-grade gold upside in a mineralised footprint now more than 1.5 kilometres wide.
In-Depth Understanding
Barton is now aiming to gain a more in-depth understanding of Tolmer with three holes of diamond drilling testing the ‘Eastern Gold Zone’.
Adding significant value to the silver at Tolmer is the identification of a growing gold source there.
The new program comes after Barton recently hit high-grade intersections including 2,240g/t silver and 51.2g/t gold in an area named the ‘Western Silver Zone’.
Silver Re-Testing
Barton’s re-testing of the silver discovery hole returned a gold hit of 4m at 13.2g/t from 48m.
The new assays also included a silver reading of up to 117 g/t from fresh rock for the first time.
The upcoming program of approximately 550m will provide key information on local structural controls and help identify future exploration targets.
“Tolmer has clear potential to add significant value to our regional development strategy [and] this DD will help improve our local structural knowledge as we work to identify the origins of such high-grade mineralisation,” managing director Alexander Scanlon said.
Soil Sampling Program
Barton is further evaluating the Tolmer potential with a recently completed soil sampling program over approximately 1.9 sq km surrounding the high-grade silver and gold discoveries, from which the company expects results in September.
The exploration work at Tolmer adds to the opportunities Barton is developing at its Tunkillia and Tarcoola gold projects in South Australia.
Barton recently decided to step-up feasibility and mining lease application programs at Tunkillia following the release of an optimised scoping study during the June quarter.
The study identified the potential production of 942,000 ounces of gold and approximately 2Moz of silver with an 0.8-year payback on a 10-year project, with $35 million in up-front capex savings.
