Barton Gold’s Resources Rise to 1.6Moz Au; Tolmer Silver Hits 17,600 g/t Assay

Resource Growth at Tunkillia

Barton Gold Holdings has delivered a robust March 2025 quarter, highlighted by a significant upgrade to its Tunkillia Gold Project in South Australia. The company announced a 120,000-ounce increase in its JORC Mineral Resource Estimate, lifting total gold resources to 1.6 million ounces and silver to 3.1 million ounces. This growth follows extensive reverse circulation drilling that confirmed depth extensions of 50 to 100 metres below the key 223 Deposit, underpinning the potential for further resource expansion.

High-Grade Silver Discovery at Tolmer

At the Tarcoola Gold Project, Barton unveiled a striking new high-grade silver zone at the Tolmer prospect. Assays revealed extraordinary silver grades, including 6 metres at 4,747 g/t Ag and a standout 1 metre intercept of 17,600 g/t Ag, located within 50 metres of surface. Alongside silver, gold grades reached up to 83.6 g/t, indicating a compelling dual-metal opportunity. The discovery of a ‘western silver zone’ distinct from the previously known ‘eastern gold zone’ has prompted plans for expedited drilling to delineate the extent of this high-grade mineralisation.

Operational Efficiency and Study Acceleration

Complementing these exploration successes, Barton has accelerated its Optimised Scoping Study (OSS) for Tunkillia, aiming for publication ahead of the original June 30, 2025 deadline. Recent metallurgical testwork confirmed improved comminution characteristics and reduced power consumption, suggesting lower operating costs and capital requirements. These efficiency gains enhance the project’s economics, building on the earlier Initial Scoping Study that forecast a 40% equity IRR and a 1.9-year payback period.

Strong Financial Position and Institutional Support

Financially, Barton remains well positioned with $7 million in cash, no debt, and a negligible net cash burn of $38,000 for the quarter. The company reported a $3.1 million profit for the half-year ending December 2024, buoyed by $5 million in gold sales and a $2.4 million R&D tax refund. Notably, Collins Street Asset Management increased its shareholding to 14.07%, reflecting growing institutional confidence amid rising gold prices.

Looking Ahead

Barton’s management is focused on advancing follow-up drilling at Tolmer to map the new silver zone’s extensions and accelerating feasibility work at Tunkillia. With a track record of asset monetisation and a low cash burn rate, the company is strategically positioned to capitalise on its expanding resource base and operational improvements in the evolving gold market.
