Barton Gold is eyeing the possibility of significant new discoveries, having identified a collection of shallow targets with its government co-funded ground penetrating radar, or “GPR”  survey over the Tarcoola Gold Project on the Gawler Craton in South Australia. The work is part of a systematic geophysical and drilling program with more refined target selection and follow-up drilling expected in coming months.

Barton’s deep GPR work is the first of its kind conducted in the Tarcoola region with preliminary interpretation of the data identifying multiple new targets only 10-50 metres below the surface. High-resolution ground based gravity surveys were also successfully completed at the Western, Eastern and Ealbara target areas with a total of 3,116 stations over an extensive 80.5square kilometres.

The company also said the assay results from the previously completed Tarcoola Phase 2 drilling are expected to arrive within weeks.

The program forms part of an exploration program co-funded by the Government of South Australia under the Accelerated Discovery Initiative Grant scheme. Barton received $300,000 in funding from the South Australian Government under the scheme for the application of innovative exploration technologies. The new gravity data will be combined with high-resolution magnetic survey data gathered during 2020 and information gleaned from the GPR conducted during July 2021. When combined with legacy data, the latest results will be used to refine the Tarcoola 3D regional structural architecture and stratigraphy, refine target selection and allow more precise follow-up drill in high priority areas.

Barton’s innovative, tech-driven approach to its exploration at Tarcoola already appears to be bearing fruit. The GPR has identified about two dozen vein-like targets, a stockwork-like intrusive anomaly only 8m below the surface and a dome-like anomaly only 12m under the desert floor. Intriguingly, all of the indicators are located within 1,500m of the historic and productive Perseverance Mine. Anomalies near the northern and southern limits of the survey are in areas with scant legacy drilling.

Importantly, GPR can achieve high-resolution images to a depth of 40-50m and clear imaging up to 70m depth on good ground. Given that the GPR survey has only covered an area of 2.6square kilometres, the targets produced from these initial results may just be the tip of the iceberg.  

Barton Gold Managing Director, Alexander Scanlon said: “We are very excited to share these preliminary results, which highlight multiple exciting new targets near the open pit. This opens up the potential for significant discoveries of new mineralisation via more precise and cost-effective drilling. We are the first to trial GPR in the Tarcoola region, co-funded by the South Australian Government’s Accelerated Discovery Initiative (ADI). To identify so many previously unrecognised shallow structures and features within this small area highlights the significant untapped potential of the Project. We look forward to pending assay results from our recent Tarcoola Phase 2 drilling program and will thereafter undertake a detailed integrated analysis to leverage our now considerable data package for large-scale discovery and reanimation of gold production at the Tarcoola Gold Project.”

Provided the new data validates key regional anomalies identified previously, the company expects to put in place plans for a follow-up program before the end of 2021.

Barton’s inventory already includes the Tarcoola Gold project, an existing brownfield open pit mine within trucking distance of its own 650,000 tonnes per annum processing plant and the Tunkillia gold project where it holds a 956,000-ounce gold resource based on 26.1 million tonnes at 1.15 g/t gold. The Tarcoola mine infrastructure includes lodging for 40 people to support mine operations and the Central Gawler Mill includes a 240-person village, workshop, labs and airstrip.

Barton is already a member of the coveted million-ounce club with 1.1 million ounces of mineral resource based on 28.7 million tonnes mineable ore at 1.2 g/t gold. It has a pipeline of advanced exploration projects and brownfield mines and also owns the only regional gold mill in the central Gawler Craton.

With a  bevy of highly prospective new targets to chase down, assays in the labs and an armoury of high-tech tools at its disposal in one of the most revered hunting grounds in Australia, Barton Gold is certainly one to watch.
