Highlights

  • The Achilles discovery delivered a maiden Mineral Resource Estimate of 38.5 million ounces silver-equivalent at South Cobar.
  • Multi-rig diamond and reverse circulation drilling continues to test strike extensions and regional anomalies.
  • The South Cobar Project sits along the southern extension of the world-class Cobar Basin mineral province.
  • Achilles exhibits sub-vertical, structurally controlled shoots of high-grade massive and semi-massive sulphides.

Australian Gold and Copper Ltd (ASX:AGC) achieved widespread industry recognition across 2026 following the delivery of an exceptional maiden Mineral Resource Estimate at its Achilles discovery within the South Cobar Project in central New South Wales. The company deployed multi-rig diamond and reverse circulation drilling to test strike extensions and regional anomalies, cementing its reputation as a premier polymetallic precious metal discovery story in the prolific Lachlan Fold Belt.

Business Model and Project Portfolio

Australian Gold and Copper is an Australian mineral exploration company focused on discovering major gold, copper, and base metal deposits in the Lachlan Fold Belt of New South Wales. The company maintains a portfolio of three district-scale projects: South Cobar, Moorefield, and Gundagai.

The primary focus is the South Cobar Project, situated along the southern extension of the world-class Cobar Basin mineral province. South Cobar hosts the high-grade Achilles polymetallic discovery alongside prospects including Boona, Hilltop, and Planet, all benefiting from accessible rail links, sealed road networks, and regional grid power.

Gold, Silver, and Copper — Commercial Drivers

Gold, silver, copper, lead, and zinc form the polymetallic commodity suite underpinning AGC's commercial value. Gold and silver provide immediate exposure to buoyant precious metal pricing, where monetary demand and inflation hedging have driven strong investor liquidity and premium valuations for high-grade deposits.

The Achilles deposit is notable for its extraordinary silver and gold endowment, yielding a maiden Mineral Resource Estimate of 38.5 million ounces silver-equivalent. Alongside precious metals, copper represents a vital growth pillar, with discoveries in the Cobar Basin commanding premium interest from major mining producers seeking long-life smelting feed to replenish depleting regional reserves.

Resource Delineation and Drilling Catalysts

The primary catalyst for AGC's commercial progress was the release of the maiden JORC-compliant resource for Achilles, which established substantial high-grade mineralisation open along strike and at depth. The deposit exhibits classic Cobar-style sub-vertical, structurally controlled shoots of high-grade massive and semi-massive sulphides.

Following the resource release, AGC accelerated multi-rig drilling across the broader South Cobar corridor. Exploration aims to expand the resource envelope at Achilles while drill-testing parallel geochemical and induced polarisation geophysical targets, proving that Achilles is part of a larger cluster of economic deposits.

Market Performance and Financial Snapshot

During the trading session on 2 October 2026, shares closed at $0.125, recording a daily movement of -$0.003 (-1.96%) within an intraday range of $0.125 to $0.13 on turnover of 37,415 shares. Market capitalisation was $41.44 million.

Over the trailing 12 months, AGC shares declined -34.21%. This retracement occurred as the market consolidated following the initial surge that accompanied the early Achilles discovery holes, with investors awaiting follow-up resource updates and preliminary metallurgical studies.

Near-Term Growth Drivers and Risks

Key catalysts include upcoming drill assay releases from step-out holes at Achilles, regional reconnaissance drilling across South Cobar, and preliminary metallurgical test work evaluating concentrate recoveries for silver, gold, and base metals.

As an exploration company without mining revenue, AGC depends on capital raisings for high-cost drilling campaigns. Risks include geological complexity, assay turnaround delays, landowner and environmental access approvals, and broad volatility across global metal markets.
