Feasibility studies to begin shortly | Targeting operations by end of 2026
HIGHLIGHTS
Challenger JORC (2012) Mineral Resources Estimate (MRE) grows to 313koz Au (10.6Mt @ 0.92 g/t), incl. 194koz Au (1.87Mt @ 3.23 g/t) in existing open pit and underground mines:
Challenger Main Open Pit: 70,000oz Au (0.65Mt @ 3.36 g/t Au);
Challenger West Open pit: 11,600oz Au (0.03Mt @ 10.7 g/t Au);
Challenger Underground (above 215mRL): 89,400oz Au (0.98Mt @ 2.84 g/t Au); and
Challenger Deeps (below 90mRL): 23,000oz Au (0.21Mt @ 3.50 g/t Au).
Almost all MRE mineralisation located in, on, or adjacent to, existing serviceable open pit and underground development – opportunities for low-cost access and production
Preliminary estimate for full reinstatement of 600ktpa Central Gawler Mill only A$26m (± 30%)
Targeting lower-cost, de-risked two phase transition to operations, with initial high-grade tailings reprocessing (as Phase 1), followed by restart of fresh rock operations (as Phase 2)
Technical programs moving directly to definitive Feasibility, targeting operations by end of 2026; conversations underway with financiers for low-dilution credit financing options
ADELAIDE, AUSTRALIA / ACCESS Newswire / September 7, 2025 / Barton Gold Holdings Limited (ASX:BGD)(FRA:BGD3)(OTCQB:BGDFF) (Barton or Company) is pleased to announce an updated MRE for its South Australian Challenger Gold Project (Challenger). This follows detailed remodelling of gold mineralisation on or near existing development drives within the historical Challenger underground mine (below the 900mRL level). This mineralisation was temporarily removed from Barton’s recent 30 June 2025 Challenger MRE update, pending final remodelling and re-estimation.
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 Challenger JORC Resources update, Barton MD Alexander Scanlon said:
“With gold Resources of over 300,000oz now confirmed adjacent to the Central Gawler Mill, the pieces are now in place for the startup of an initial multi-year ‘Stage 1’ operation. This represents a significant opportunity for Barton to join a select few of its peers by transitioning to operations at a period of record high gold prices.
“Our fully permitted Central Gawler Mill also offers considerable leverage in successfully delivering this outcome, with a potentially shorter, lower-cost, and lower-risk pathway to operations and BGD’s re-rating to ‘producer’ status. A successful outcome could then generate revenues and cash flow to fund our planned regional growth.
“We are now moving directly to definitive Feasibility studies targeting a two phase, de-risked development and the start of initial ‘Stage 1′ operations by the end of 2026. Barton has a very exciting 18 months ahead as we navigate this next stage of our corporate evolution.”
