  accessnewswire.com
   ADELAIDE, AU /  ACCESS Newswire / October 22, 2025 / Barton Gold Holdings Limited (ASX:BGD)(OTCQB:BGDFF)(FRA:BGD3) (Barton or the Company)  is pleased to confirm that geotechnical drilling has started in support  of a recently launched Definitive Feasibility Study for ‘Stage 1'  production (Stage 1 DFS) at the Company's South Australian Challenger Gold Project (Challenger).1
  The  planned program includes 5 sonic drilling holes to recover TSF1  materials for laboratory testing, 24 holes for Cone Penetration Testing (CPTu) and further laboratory testing, and 3 holes for push tube density testing.
  The  program is expected to take three weeks to complete, with the results  to inform the dry recovery of TSF1 tailings materials, detailed mine  design, a mining schedule and estimate of mining costs for the Stage 1  DFS.

  Commenting on the start of geotechnical drilling, Barton Managing Director Alexander Scanlon said:
  "With  the Stage 1 DFS now underway, we are excited to kick off the first of  several production-related work programs that will inform key elements  of mine design, scheduling, equipment selection and operating costs for  tailings recovery.
  "Following a $15m placement led by  Franklin Templeton, Barton is well funded to advance the restart of  operations at its Central Gawler Mill, with approximately $20m cash in  the bank and credit financing discussions underway.
  "We are  now on the road to production, leveraging our fully permitted Central  Gawler Mill to operations and growth. This is an invaluable stepping  stone for our vision to become South Australia's largest independent  gold producer."
  Authorised by the Managing Director of Barton Gold Holdings Limited.
