Story Continues

"Tunkillia's Optimised Scoping Study highlights a project that, in operation today, would generate nearly $1 billion in revenue and $30 million in State royalties, every year, in South Australia. Together with our Challenger, Tarcoola, and Wudinna Gold Projects, and our new Tolmer Silver discovery, our long-term objectives for the State are even greater.

"As a leading investor in South Australia, we aim to develop the State's largest independent precious metals producer, to be a major contributor to the State's economy, and to create opportunity for the communities in which we operate.

 

"Sylvia joins our leadership ranks as we enter an exciting new phase for the Company. During 2026 we will continue building out the team that will deliver our vision for the State. We are therefore pleased to welcome another highly experienced South Australian who shares Barton's ambition to make a significant, long-term contribution to the State.
