Central Gawler Mill Refurbishment Estimated at A$26m

Preliminary evaluation confirms low-cost pathway to production

HIGHLIGHTS

  • Capital cost for full reinstatement of Central Gawler Mill to original design basis (600ktpa fresh ore) estimated at only ~A$26m (±30%); processing cost estimated at only A$44.50/t

  • Significant cost advantages versus building a new mill, or utilising third party toll milling

  • Targeting feasibility by end of 2025 to support initial ‘Stage 1′ operations by end of 2026; early conversations underway for low-dilution credit and working capital financing

ADELAIDE, AUSTRALIA / ACCESS Newswire / July 20, 2025 / Barton Gold Holdings Limited (ASX:BGD)(FRA:BGD3)(OTCQB:BGDFF) ( Barton or Company ) is pleased to share that preliminary engineering analysis has confirmed that full reinstatement of the Central Gawler Mill ( CGM ) to its original 600ktpa fresh ore configuration is estimated at only A$26m (±30%). Full details are contained in the complete announcement, which can be accessed on the ASX website, the investor section of Barton’s website, or directly by clicking here.

Commenting on the refurbishment analysis, Barton Managing Director Alexander Scanlon said:

“Our Central Gawler Mill offers significant leverage for a low-cost transition to production. A refurbishment cost of only A$26m is a fraction of the cost of building new, and the option to defer material elements of capex if first reprocessing tailings offers further advantages. Existing infrastructure also offers more financing options, and we don’t need to seek third party toll milling services while sacrificing profitability. The building blocks for our regional development strategy are now in place, and we look forward to kicking it off at the Central Gawler Mill.”
