Barton Gold Holdings Limited (ASX: BGD) has commenced a Phase 3 drilling campaign at the Tarcoola Gold Project in South Australia.
Prior Phase 1 and Phase 2 programmes during 2020 and 2021 identified ~200m depth extensions of mineralisation and the new ~350m long shallow high-grade Perseverance West gold zone extending from the SW end of the Perseverance open pit mine.
Phase 3 drilling is expected to comprise approximately 24 drill holes for a total ~4,700 metres of reverse circulation drilling, seeking to further extend the Perseverance West gold zone to establish new, easily accessible Mineral Resources, and to test the priority School and Ealbara regional prospects.
Ealbara lies on a major inflection zone of the Lake Labyrinth Shear Zone (LLSZ). Recent drilling by Indiana Resources has identified significant gold mineralisation in the LLSZ at the Minos and Ariadne prospects.
Perseverance West
Tarcoola Phases 1 and 2 drilling, completed during 2020 and 2021, identified a new ~350m long, shallow and high-grade gold zone immediately adjacent to the SW end of the Perseverance open pit mine.
The Perseverance West gold zone is offset and parallel to the Deliverance Target, extending to ~100m depth at the SW open pit wall, and has been confirmed to a depth of ~125m from surface at the western extent of its ~350m strike, and remains open to extension along strike and to depth.
Assay results from prior drilling at the Perseverance West gold zone and Deliverance Target include:
Perseverance West • 4m @ 6.85 g/t Au from 28m • 7m @ 9.72 g/t Au from 42m • 5m @ 20.6 g/t Au from 59m • 6m @ 8.76 g/t Au from 96m • 4m @ 11.4 g/t Au from 111m • 5m @ 48.9 g/t Au from 115m
Deliverance Target • 5m @ 20.6 g/t Au from 59m • 2m @ 56.7 g/t Au from 92m • 4m @ 11.4 g/t Au from 107m • 4m @ 14.8 g/t Au from 138m • 6m @ 43.6 g/t Au from 197m • 3m @ 33.7 g/t Au from 220m.
Most intersections around the pit are not yet included in Resource estimates. Barton is targeting ~2,200 metres of drilling to support the definition of an initial, easily accessible Mineral Resource for this area.
“Last year’s Phase 2 drilling successfully identified a new and potentially high-value opportunity on our open pit at Perseverance, and our numerous geophysical studies have confirmed a long list of exciting regional targets,” Managing Director, Alexander Scanlon, said.
“This year our focus at Tarcoola will be twofold: (1) Establishing an initial Mineral Resource accessible via our existing open pit, and new regional discoveries across an historically rich mineral domain.
“Barton plans to complete more than 20,000 metres drilling in the coming 6 months. We are excited to test several newly validated targets, with a focus on significant growth of Tarcoola’s mineralised footprint.”
Ealbara Prospect (LLSZ)
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 programme. 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.
Image processing and 3D inversion modelling of gravity data acquired over the Ealbara prospect during September 2021 supports a strong correlation of density bodies within the interpreted position of the LLSZ. These results confirm multiple prospective structural targets at Ealbara.
The Ealbara prospect has not been drilled historically despite its scale and prospective amenable setting to host gold mineralisation.
Barton is targeting ~2,200 metres of initial drilling to test the thickness of the local Gawler Range Volcanics (GRV), validate the structural predictions hypothesised by Barton’s new geophysical modelling, and test for anomalous gold mineralisation across ~1km of LLSZ strike at Ealbara.
