Barton bullish on bolstering Tunkillia’s development profile

Barton Gold (ASX:BGD) has returned an intersection of 3.83m at 68 grams per tonne of gold from 104.1m depth at ‘high-grade’ target Area 191 within its Tunkillia Gold Project.

The $45.21 million market capitalisation company says diamond core is assisting in structural analysis of the zone where visible gold mineralisation appears concentrated around clusters of ‘high-grade’ intercepts.

Barton Managing Director Alex Scanlon says the Area 191 drilling results are the highest-grade assays yet at the 1.38 million ounce Tunkillia project and suggests potential for a ‘high-grade’ system northeast of the current 1.38 million ounce JORC resource.

He tells Mining.com.au ‘obviously’ the company is very excited with these assays.

“Tunkillia is already scaling up nicely and a high-grade source of mineralisation within the project itself could significantly enhance its development profile.”

Scanlon adds that such ‘high-grade’ mineralisation could significantly enhance Tunkillia’s development profile, something Barton will review further as it builds out the project’s footprint.

The Area 191 gold zone presently spans some 250-300m width and 650m strike length along a predominantly north-northwest strike orientation.

During August 2021 Barton completed 8 reverse circulation (RC) holes totalling 1,128m drilling at the target, which the company says resulted in shallow ‘high-grade’ assays complementing results from earlier drilling by prior owners.

Results from Barton’s 2021 program included TKB29: 10m @ 1.31g/t Au from 50m, including 3m @ 3.45g/t Au from 55m; and TKB28: 4m @ 3.91 g/t Au from 115m, including 1m @ 7.90 g/t Au from 118m.

Comparatively, historical drilling results included LRC218: 11m @ 6.24g/t Au from 80m, including 1m @ 60.6g/t Au from 89m; and LRC224: 2m @ 35.05g/t Au from 68m, including 1m @ 69.6g/t Au from 68m.

During October 2023 Barton completed 2 diamond drilling (DD) holes at Area 191. The objective was to gain additional information regarding the orientation of mineralisation and determine the next steps to pursue a potential JORC resource.

Barton says key new Area 191 drilling of interest is hole number TKB124D, which was drilled at a 90 degree angle to a southeast-northwest trending structure and (from 104.1m depth) intersecting 3.83m @ 68g/t gold in a quartz vein containing significant gold mineralisation visible in this section of the core.

Prior drilling at Area 191 also encountered ‘high-grade’ gold in multiple locations but was lacking in structural context. Barton notes hole TKB124D was drilled to test the structural model and has confirmed the existence of a north-dipping fault with significant intervals of high-grade gold present in the hanging wall and extending to the north away from the fault.

The company says therefore hole TKB124D appears to confirm prior drilling around this location and indicates the hanging wall zone as a priority up-dip and down-dip target for high-grade mineralisation.

Scanlon tells this news service: “We expect a great deal more news soon, with Tunkillia’s Area 51 gold zone now in JORC resource modelling, and another 5,000m of drilling results pending for both the Tunkillia project and the Tarcoola project – including the historical high-grade Perseverance open pit mine.

After that, we will be drilling high-grade targets again at the projects, so we can expect a busy and exciting 2024 ahead.”

Barton Gold is an ASX, OTCQB, and Frankfurt Stock Exchange-listed gold explorer with a pipeline of advanced exploration projects in South Australia. 

As of 31 December 2023, Barton had a $4.6 million cash balance, which it says provides significant working capital for ongoing Tarcoola and Tunkillia programs.

During the past quarter the company completed an intensive growth program of more than 20,000m RC and DD exploration drilling across the Tarcoola Gold and Tunkillia Gold projects. This resulted in a JORC Mineral Resources Estimate (MRE) upgrade for Tunkillia during December 2023, to a total 1.38Moz Au, following its April 2023 JORC upgrade (from 965,000oz to 1.15Moz).

Barton also published a 3D model of the sub-surface architecture of its Tarcoola Goldfield, providing the first consistent structural framework for historical high-grade gold occurrences since its 1893 discovery.
