Barton Gold Holdings Limited develops gold and silver assets in the Gawler Craton of South Australia and trades on the ASX, OTCQB and Frankfurt Stock Exchange. Company news centers on exploration and development work across Tunkillia, Challenger, Tarcoola, Wudinna and Tolmer, including drilling programs, assay results, JORC Mineral Resource updates, metallurgical evaluation and technical studies.
Recurring updates also cover the wholly owned Central Gawler Mill, restart planning tied to brownfield mining assets, conference presentations and resource-development strategy. Project announcements frequently discuss gold and silver mineralisation, open-pit and near-surface targets, diamond and reverse-circulation drilling, and study work supporting future mine development.
Barton Gold Holdings (OTCQB:BGDFF) has announced promising metallurgical testwork results from its Wudinna Gold Project in South Australia. The tests revealed exceptional gold recoveries of up to 99.3% using conventional gravity and leaching processes. At the Barns Deposit, approximately 90% of contained gold can be concentrated to grades of 20-25 g/t Au through efficient flotation, with overall recoveries of 97-99%. The Baggy Green Deposit showed gold recoveries of 91% in the supergene zone and 98-99% in the primary zone.
The company is exploring options to leverage its existing Central Gawler Mill and future Tunkillia mill infrastructure by trucking high-grade concentrates. At current gold prices, the concentrate would have a contained value of over AUD $4,000 per tonne, making transportation economically viable.
Barton Gold Holdings (OTCQB:BGDFF) has announced an updated Mineral Resources Estimate (MRE) for its Challenger Gold Project in South Australia, with total resources now exceeding 313,000 ounces of gold at 0.92 g/t. The resource includes 194,000 ounces at 3.23 g/t within existing open pit and underground mines.
The company plans a two-phase development approach, starting with high-grade tailings reprocessing followed by fresh rock operations. The Central Gawler Mill reinstatement is estimated at A$26 million (±30%). Barton is targeting the commencement of 'Stage 1' operations by the end of 2026, with definitive feasibility studies beginning shortly.
Barton Gold Holdings (OTCQB:BGDFF) has completed diamond drilling at its high-grade Tolmer gold and silver prospect within the South Australian Tarcoola Gold Project. The program consisted of three holes totaling 595.3 metres in the 'eastern gold zone' to identify structural controls for future targeting.
The Tolmer prospect has yielded exceptional results, with the March 2025 discovery hole ranking as the 5th highest-grade silver intersection globally in H1 2025, featuring 6m @ 4,747 g/t Ag from 46m depth. The mineralized footprint has expanded to ~1.5km wide, with impressive grades reaching up to 83.6g/t Au and 17,600g/t Ag. Recent RC drilling has extended silver mineralization and added high-grade gold in the 'western silver zone'.
A soil sampling program covering ~1.9km² was completed in July 2025, with approximately 430 samples collected and assays expected in September 2025.
Barton Gold Holdings (OTCQB:BGDFF) has initiated diamond drilling at its Tolmer prospect within the South Australian Tarcoola Gold Project. The initial program comprises 3 holes totaling ~550 metres in the 'eastern gold zone' to study structural controls and guide future targeting.
The Tolmer discovery has demonstrated significant potential with impressive grades up to 83.6g/t Au and 17,600g/t Ag. The March 2025 discovery hole ranked as the 5th highest-grade silver intersection globally in H1 2025, yielding 6m @ 4,747 g/t Ag from 46m depth. Recent assays have extended high-grade silver horizons and revealed coincident high-grade gold up to ~13g/t Au within a mineralized footprint spanning approximately 1.5km wide.
Barton Gold Holdings (OTCQB:BGDFF) has secured the grant of 'New Tenements' for its Wudinna Gold Project in South Australia. The company received approval for five Exploration Licenses (ELs 7074-7078), marking a significant milestone as a precedent-setting M&A transaction under South Australia's new regulations for tenement subdivision.
As part of the Final Settlement, four of the exploration licenses will be transferred directly to Barton, while the company will acquire gold and other rights over EL 7074. The transaction includes an $800,000 share issuance to Cobra Resources PLC, subject to Escrow and Orderly Market Agreements.
Barton Gold Holdings (OTCQB:BGDFF) has reported significant new assay results from its Tolmer discovery at the Tarcoola Gold Project in South Australia. The drilling program has revealed exceptional high-grade silver values up to 2,240 g/t Ag and gold values up to 51.2 g/t Au in the 'Western Silver Zone'.
Key findings include extensions of a shallow, broad 'upper horizon' of silver (~100 g/t Ag) in the oxide zone, and a 'transitional/lower horizon' containing high-grade silver (~200-4,750 g/t Ag). Notably, the re-assay of the silver discovery hole confirmed high-grade gold mineralization of 4m @ 13.2g/t Au from 48m depth. The company plans to commence diamond drilling next week to further investigate this promising discovery.
Barton Gold Holdings (OTCQB:BGDFF) has successfully secured rights to acquire the Wudinna Gold Project following approval from Cobra Resources PLC shareholders on July 24, 2025. The Wudinna Project, located in South Australia's Eyre Peninsula, contains 279,000 oz Au with a grade of 1.5 g/t Au across multiple deposits.
The acquisition terms include total consideration of $5.5 million, comprising $500,000 in cash and $5 million in Barton shares. Additional contingent benefits include $2 million in shares upon reaching a 500koz gold JORC resource and up to $7.5 million in production benefits. With this acquisition, Barton's total JORC Mineral Resources have increased to 2.14Moz Au (78.9Mt @ 0.85g/t Au) and 3.10Moz Ag.
Barton Gold Holdings (OTCQB:BGDFF) has announced the publication of an updated corporate presentation ahead of its participation in the Noosa Mining Conference on July 22, 2025.

Barton Gold Holdings (OTCQB:BGDFF) has announced that preliminary engineering analysis estimates the cost to fully reinstate its Central Gawler Mill (CGM) to its original 600ktpa fresh ore configuration at approximately A$26 million (±30%). The processing cost is estimated at A$44.50 per tonne.
The company aims to complete feasibility studies by the end of 2025 to support initial 'Stage 1' operations by end of 2026.
