Australian Gold and Copper Ltd
Australian Gold and Copper Ltd (ASX: AGC) has announced outstanding new drilling results from its Achilles deposit that strengthen the company's position as a rapidly emerging silver-gold producer in NSW's proven Cobar Mining District. The incredible drilling results from Australian Gold and Copper reveal multiple broad, high-grade intervals that extend the deposit at depth, including spectacular grades of 1,123g/t silver equivalent over 3 metres.
The new results come from five diamond drill holes that were not included in the company's initial 38.5 million ounce silver equivalent resource announced in December 2025, highlighting significant potential for near-term resource growth.
Outstanding High-Grade Intersections Drive Resource Expansion
The latest drilling results from the northern high-grade zone at Achilles have delivered exceptional mineralisation that surpasses previous expectations. Furthermore, these incredible drilling results from Australian Gold and Copper demonstrate the deposit's exceptional grade continuity at depth.
Key Drilling Highlights:
| Hole ID | Interval | Silver Equivalent Grade | Gold | Silver | Lead+Zinc | Depth |
|---|---|---|---|---|---|---|
| A3RCD083 | 33m | 264g/t AgEq | 1.6g/t Au | 58g/t Ag | 1.9% | 189m |
| – including | 21m | 365g/t AgEq | 2.5g/t Au | 87g/t Ag | 1.5% | 192m |
| – further inc. | 3m | 1,123g/t AgEq | 9.5g/t Au | 227g/t Ag | 0.7% | 205m |
| A3RCD084 | 16m | 279g/t AgEq | 0.4g/t Au | 89g/t Ag | 5.7% | 150.4m |
| – including | 9.5m | 435g/t AgEq | 0.5g/t Au | 146g/t Ag | 8.8% | 151.4m |
These results extend the high-grade mineralisation around the previously reported exceptional 20m at 809g/t AgEq interval, which included 6m at 2,474g/t AgEq – results that Managing Director Glen Diemar described as delivering "exceptional silver and gold grades over significant thicknesses."
Management Commentary:
"Our Achilles silver-gold deposit is proving to be quite robust and clearly has more mineralisation to uncover as drilling continues. This is a recipe for resource growth as these holes, along with others with assays pending, did not make it into the initial Mineral Resource Estimate." – Glen Diemar, Managing Director

Strong Foundation: 38.5 Million Ounce Silver Equivalent Resource
The Achilles deposit already hosts a substantial initial Mineral Resource Estimate of 10.3 million tonnes at 116g/t silver equivalent, containing 38.5 million ounces of silver equivalent. This resource provides a solid foundation for the company's growth strategy, especially given the incredible drilling results from Australian Gold and Copper continue to expand the deposit's potential.
Current Resource Breakdown:
| Category | Tonnage (Mt) | Silver Equivalent (g/t) | Silver Equivalent (Moz) |
|---|---|---|---|
| Open Pit Indicated | 4.7 | 141 | 21.5 |
| Open Pit Inferred | 3.2 | 72 | 7.3 |
| Underground Indicated | 0.3 | 130 | 1.1 |
| Underground Inferred | 2.2 | 124 | 8.8 |
| Combined Total | 10.3 | 116 | 38.5 |
The resource demonstrates strong metallurgical characteristics, with recent testing showing robust recoveries of 83% for silver, 90% for gold, 95% for zinc and 92% for lead.
Understanding Silver Equivalent Grades
Silver equivalent (AgEq) is a key metric that allows investors to compare polymetallic deposits by converting all valuable metals into a single silver-equivalent number. This calculation considers:
• Metal recoveries from metallurgical testing
• Current market prices for each metal
• Realistic recovery expectations during processing
For Achilles, the formula incorporates silver, gold, lead and zinc based on proven recovery rates. This provides investors with a standardised way to evaluate the economic potential of the mineralisation, with higher AgEq grades indicating more valuable rock per tonne.
Why this matters for investors: Silver equivalent grades allow direct comparison between different mining projects and provide a clearer picture of the economic value contained in the deposit.
Expanding the Exploration Footprint
Beyond the main Achilles deposit, the company is systematically exploring along the 6-kilometre Achilles Shear Zone. Recent drilling at the Achilles Quarry target, located 5km south of the main deposit, returned encouraging results including:
• 9m at 45g/t AgEq from 90m in hole A2RC022
• Mineralisation that remains open at depth and along strike
• Similar geological characteristics to the main Achilles deposit
This exploration success demonstrates the district-scale potential of Australian Gold and Copper's land position in the proven Cobar Mining District. Moreover, the incredible drilling results from Australian Gold and Copper suggest similar high-grade zones may exist throughout the broader project area.
Aggressive Growth Timeline Ahead
Australian Gold and Copper has outlined an ambitious development programme designed to more than double the company's resource endowment by year-end:
Immediate Catalysts (Next 6 Months):
• Six additional diamond hole assays expected in coming weeks
• Resource upgrade at Achilles incorporating recent high-grade results
• Drilling recommencement later in Q1 2026
Major Growth Initiative (March 2026):
• 10,000-metre drilling programme commencing at Browns-Evergreen deposit
• Targeting new Mineral Resource Estimate at second major deposit
• Dual-asset resource growth strategy across South Cobar Project
The company's systematic approach to resource expansion is supported by a strong cash position and proven track record of discovering high-grade mineralisation.
