American Marconi Wireless News - 'Stage 1' Resources at Central Gawler Mill Grow to 223koz Au

ADELAIDE, AUSTRALIA / ACCESS Newswire / June 29, 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).

Challenger JORC (2012) Mineral Resources Estimate (MRE) grow to 223koz gold (9.56Mt @ 0.72 g/t Au), including 81,200oz Au contained in the existing high-grade open pit zones.

Barton has identified several potential sources of economically viable gold mineralisation adjacent to the Central Gawler Mill for use as lower-cost and lower-risk 'Stage 1' mill feed, and is targeting feasibility studies by the end of 2025, with initial 'Stage 1' operations by the end of 2026.

Barton is also evaluating the potential to reprocess (in particular) Tailings Storage Facility (TSF) 1 to extract gold as a part of Stage 1 operations. TSF1 was constructed in 2002 and decommissioned during 2009, during which time it serviced open pit mining operations from Challenger Main and the highest-grade portion of the historical U/G mine. This highest-grade mineralisation was processed last during the operation of TSF1, resulting in a higher-grade ring of mineralisation located around the periphery of TSF1 where discharge spigots were located. Examples of the consolidation of higher-grade mineralisation around the periphery of TSF1 include:

Commenting on the JORC Mineral Resources update, Barton MD Alexander Scanlon said:

"As indicated to the market for the past ~24 months, we have been analysing the potential for JORC Mineral Resources in the immediate vicinity of our fully permitted Central Gawler Mill. This infrastructure is a significant leverage point for BGD's investors, and provides the option for a shorter, lower-cost, and lower-risk pathway to operations and the re-rating of BGD to 'producer' status. There is significant arbitrage value in this 'real option'.

"With the sustained upward move in gold prices, we will now look to exercise that option. During the balance of 2025 we will complete feasibility analyses to determine the preferred development pathway, with the objective to commence our initial 'Stage 1' operations before the end of 2026."
