The news comes at the perfect time, with Barton accelerating all development programs for a new district-scale gold production platform in South Australia.

"We are targeting the start of initial 'Stage 1' operations at our existing Central Gawler Mill from the end of 2026. We are also aiming, by that time, to complete a Pre-Feasibility study and submit a Mining Lease application for our 'Stage 2' large-scale Tunkillia Gold Project which is intended to deliver our long-term production target of 150kozpa gold.

"I would like to acknowledge and thank our incredible team who dedicate themselves every day to delivering a major success for the State of South Australia, and our investors, large and small, who have supported us along the way."
