Barton Gold Holdings Limited announced that image processing and 3D modelling of detailed gravity survey data acquired in three key regional target areas of the Tarcoola Gold Project during September 2021 has confirmed multiple prospective structural targets. Several of these targets were first identified by Barton through reprocessing of existing seismic data and new magnetic and ground penetrating radar (GPR) surveys during 2020 and 2021. The gravity surveys have also identified a new, previously unrecognised large-scale anomaly beneath Mining Lease 6455.

Ealbara is located in the northern part of the Tarcoola project area on the Lake Labyrinth Shear Zone (LLSZ) and will be a priority target in Barton's upcoming regional Tarcoola drilling program. The LLSZ is a major fault zone known to host significant gold mineralisation at Indiana Resources Limited's nearby Minos and Ariadne prospects where drilling has intersected broad, high-grade gold mineralisation. Ealbara is located within an interpreted major inflection of this regional structure, coincident with an historically defined, discrete gold-in-calcrete anomaly (Figure 2 below).

Inversion modelling of gravity data supports a strong correlation of density bodies within the interpreted position of the LLSZ, further validating the prospectivity of this target.
