Barton Gold identifies new drill targets following gravity surveys at Tarcoola

Barton Gold (ASX:BGD) reports that it has identified a series of prospective structural targets at its Tarcoola Gold Project following image processing and 3D modelling of detailed data from gravity surveys carried out in September 2021.

The results have confirmed priority regional structural targets identified from previous seismic, magnetic and ground penetrating radar surveys across three key regional areas, and include a new ‘large-scale’ gravity anomaly beneath the Tarcoola mining lease.

Speaking on the news, Barton Gold Managing Director Alexander Scanlon said: “Barton is rapidly building a new geological model for Tarcoola by combining traditional and innovative technologies. These exciting results cross-validate our prior interpretations of multiple historical and new data sets, reinforcing the significant geological prospectivity for multiple regional discoveries at Tarcoola.

These exciting results cross-validate our prior interpretations of multiple historical and new data sets”

Significant growth of Tarcoola’s mineralised footprint will be a high priority for Barton during 2022.”

The company notes that several of the targets were generated via reprocessing of existing seismic data and new magnetic and ground penetrating radar surveys carried-out in 2020 and 2021.

Ealbara prospect

The Ealbara prospect is situated in the northern part of the Tarcoola project area, and will be treated as a priority target during the project’s upcoming drilling program. It sits along the Lake Labyrinth Shear Zone, a major fault zone which hosts ‘significant’ gold mineralisation at the nearby Minos and Ariadne prospects (Indiana Resources).

Tarcoola Western targets

A major gravity high signature was detected at the eastern margin of a ‘significant’ gravity low which Barton believes is attributable to Paxton Granite plus a possible Hiltaba Suite granitoid.

This may point to alteration along the margin, which is considered ‘highly prospective’ for gold mineralisation.

This area houses the Dark Hill and Warburton prospects, which are both associated with gold-in-calcrete anomalies. Warburton has been subject to historical exploration work which encountered ‘significant’ mineralisation, and has been identified as a priority target for drill testing.

Tarcoola Central targets

A series of structurally-defined target areas have been identified from gravity survey data over the central Tarcoola area, on the same mining lease that contains the Perseverance open pit mine.

The company notes that these structures correspond with data generated from ground-penetrating radar surveys completed during 2020 and 2021.

A new ‘strong’ density anomaly has been identified immediately to the northwest of the School prospect, with Barton noting that it may be due to alteration, a combination of geological contacts and a dyke or a discrete intrusion.

Moving forward

Data from these most-recent gravity surveys is set to be integrated with existing geological, geochemical and geophysical data sets in order to better understand and prioritise targets for further testing.
