Barton Gold’s high-grade Tolmer discovery signals new chapter for Tarcoola project in SA
Barton Gold (ASX: BGD) (OTCQB: BGDFF) says the Tarcoola gold story has entered another exciting chapter after receiving new assay results from its Tolmer system in South Australia.
New high-grade assays have now confirmed a promising gold-mineralised system at Tolmer, which lies within the Tarcoola project.
The Tolmer find comes as Barton continues a range of ongoing activities aimed at bringing the historic Tarcoola gold project to commercialisation.
New mineralised system
“We are excited to confirm that the first significant test of Tarcoola’s new structural model has confirmed a new gold-mineralised system at Tolmer,” managing director Alexander Scanlon said.
“We have also successfully intersected high-grade mineralisation at multiple other targets, demonstrating Tarcoola’s broader potential to host multiple shallow, high-grade gold zones.”
“We are also awaiting further assay results from the open-pit Perseverance mine, where we are hoping to convert further shallow mineralisation in the pit floor into additional high-grade resources for a ‘Stage 1’ operation.”
A recent seismic survey mapped several new and untested structures across the Tarcoola gold field and identified key targets for ‘repeats’ of the historic Perseverance gold system.
High-grade zone
Barton believes assays from approximately 100-metre spaced drill lines at Tolmer indicate potential for a zone of continuous high-grade mineralisation.
The company is currently planning follow-up drilling programs later this year, including aircore and further reverse circulation (RC) definition drilling, to help define the potential extent of the Tolmer footprint and to follow up other higher-grade results.
Drilling in 2024 will also follow up high-grade results from neighbouring targets and test large-scale regional targets along Tarcoola’s Lake Labyrinth Shear Zone and the neighbouring Tunkillia gold project.
Regional drilling
Approximately 11,250m of RC drilling was completed between March and July 2024 across targets from its latest Tarcoola structural interpretations including the Perseverance open-pit mine and targets to the west.
Following this drilling, Barton confirmed a JORC mineral resource estimate of approximately 20,000 ounces of gold at around 2 grams per tonne in the Perseverance pit floor at Tarcoola that it hopes the high-grade Tolmer find will add to.
Drilling has also intersected gold mineralisation with a significant intercept value above 1 gram-metre and other high-grade results across neighbouring targets including School, Old Flame and Warburton.
