223 Deposit delivers 20% boost to Tunkillia Mineral Resource for Barton Gold

Australian gold explorer Barton Gold (ASX:BGD) has increased the Mineral Resource Estimate (MRE) at its Tunkillia Gold Project by about 189,000 ounces following drilling at the 223 Deposit.

The company reports the new MRE, which now stands at 38 million tonnes @ 0.94g/t Au for 1.15 million ounces, was informed by 41 new reverse circulation (RC) holes for a total of 9,901m, and 5 new diamond drillholes for 1,346m.

Barton says the 223 Deposit MRE was updated for potential development as a bulk open pit operation targeting efficiencies of scale and ‘strong’ grade reconciliation. Tighter grade capping and more internal dilution has yielded a ‘higher’ confidence and lower risk model for future investment. The company also says the deposit has a broad, 300m long ‘high-grade’ core with potential to enhance development economics.

Adding 189,000 ounces Au of new resource for only $12/oz is an exceptional result”

Recent drilling in the 223 Deposit was designed to target potential extensions to depth, and new gold zones in areas that were not previously tested due to low historical gold prices and limited investment.

Barton reports a lack of drilling to depth was evident in 2 key areas of the deposit, one northern and one southern, where the 2020 MRE resource shell was very shallow. The company says its drilling during 2022 and 2023 confirmed ‘substantial’ mineral extensions to depth and has extended resources to depth by up to 150m.

Commenting on the MRE update, Barton Gold Managing Director Alex Scanlon said: “These results are a clear validation of the company’s thesis for Tunkillia.

Adding 189,000 ounces Au of new resource for only $12/oz is an exceptional result, and it further confirms the value of extensional drilling in the 223 Deposit.

This update marks an important step forward in our long-term development objectives. We will follow-up these results, and other key regional targets, later this year.

The 223 Deposit itself remains open to further extensions, and we have already confirmed more than 1km of new gold mineralisation nearby. This all points to a very large-scale system, and we look forward to working our way down the next about 20km of untouched shear along strike.”

Barton reports the updated MRE has grown its total attributable JORC mineral resource endowment by 17% to 40.6 million tonnes @ 1g/t Au for 1.297 million ounces.
