Barton Gold Holdings Limited (ASX: BGD) has delivered exceptional results from its latest soil sampling program at the Tolmer prospect, indicating significant extensions of high-grade mineralisation that could transform the Company’s South Australian operations.
The latest assays suggest the discovery of new exploration targets and potential northwest-southeast orientation of mineralisation across the highly prospective Tarcoola Gold Project.
Record-Breaking Silver Intersections Drive Exploration Success
The Tolmer discovery continues to deliver world-class results following March 2025’s breakthrough hole that ranked as the 5th highest-grade silver intersection reported globally during the first half of 2025.
That standout result of 6 metres at 4,747 g/t silver from just 46 metres depth has been complemented by subsequent drilling confirming extensions of high-grade silver ranging from 200 to 4,750 g/t Ag within the ‘western silver zone’.
Tolmer cross-section highlighting the 6m @ 4,747 g/t silver intersection and associated gold zones
Recent highlights include:
- Emergence of high-grade gold alongside silver (5-50 g/t Au)
- Broad surface gold, silver and lead anomalism across Tolmer
- New coincident Au-Ag-Pb targets identified between western and eastern zones
- 595.3 metres of oriented diamond drilling completed with results pending
Strategic Position in Australia’s Premier Gold Region
Barton Gold has established a commanding presence in South Australia’s Gawler Craton, one of the country’s most prolific mineral exploration regions. The Company operates three major projects spanning over 3,000 square kilometres in this highly prospective geological province.
The Gawler Craton hosts several world-class deposits including BHP’s Olympic Dam and OZ Minerals’ Carrapateena copper-gold operations, making it a focal point for Australian mining companies seeking large-scale discoveries.
Barton’s Project Portfolio:
- Tarcoola Gold Project: 20,000oz Au in fully permitted open pit mine plus Tolmer discovery
- Tunkillia Gold Project: 1.6Moz Au & 3.1Moz Ag JORC Mineral Resources
- Challenger Gold Project: 313,000oz Au with fully permitted Central Gawler Mill
Technical Breakthrough Reveals System Scale
Managing Director Alexander Scanlon highlighted the significance of the latest findings, stating the assays provide “the first hints as to orientation at Tolmer, indicating a potential overall northwest-southeast trend to the western silver zone.”
The comprehensive soil sampling program covered approximately 1.9 square kilometres around the Tolmer discoveries, with 443 samples collected at systematic spacings to map the mineralisation footprint.
Key technical achievements include:
- Maximum gold-in-soil: 187ppb in western Tolmer zone
- Maximum silver-in-soil: 23.7ppm with contours ranging 0.5-5ppm
- Systematic grid sampling: 100m x 100m spacing with selected 50m x 50m infill
- Advanced analytical methods: Ultrafine+™ workflow by LabWest Minerals Analysis
Market Recognition Drives Share Price Surge
Barton Gold’s exceptional exploration success has translated into outstanding market performance, with shares delivering approximately 315% returns over the past 12 months according to recent trading data.
The Company currently trades with a market capitalisation of around $240 million, reflecting strong investor confidence in its development pipeline and exploration potential.
Gold prices have provided additional support, with the precious metal gaining nearly 48% over the past year amid global economic uncertainties and increased safe-haven demand.
Upcoming Catalysts and Development Timeline
The immediate focus centres on pending assay results from the 595.3-metre oriented diamond drilling program, with results expected in early November 2025. This data will provide crucial structural interpretation to guide future targeting across the Tolmer system.
Near-term milestones include:
- Diamond drilling assay results (November 2025)
- Structural interpretation and follow-up targeting
- Resource estimation work based on expanded footprint
- Integration with existing 2.2Moz Au & 3.1Moz Ag JORC resources
The Company targets future gold production of 150,000 ounces annually and maintains 100% ownership of the region’s only gold processing facility through its Central Gawler Mill.
Barton Gold’s strategic tenement position in South Australia’s highly prospective Gawler Craton region
According to the South Australian Government, the Gawler Craton remains significantly under-explored despite hosting some of Australia’s largest mineral deposits, providing substantial upside potential for companies like Barton Gold.
