Highlights

  • 62% of the Gimlet resource converted to the JORC Indicated category through infill RC and diamond drilling.
  • Toll-treatment commercial framework established with regional mill operators to commercialise without standalone plant.
  • Riverina East Gold Project acquisition adds contiguous prospective greenstone tenure north of Kalgoorlie.
  • FAU shares closed flat at $0.008, a market capitalisation of $30.11 million, demonstrating price stability.

Fifteen kilometres northwest of Kalgoorlie, First Au(ASX:FAU) has built a mining case for Gimlet without a processing plant — converting 62% of the mineral resource to Indicated confidence and securing a toll-treatment framework that puts a commercial pathway on the table while regional mills sit idle nearby.

Kalgoorlie Proximity and Victorian Exposure

First Au's primary development asset is the 100%-owned Gimlet Gold Project, located 15 kilometres northwest of Kalgoorlie in Western Australia's Eastern Goldfields. In Victoria, the company holds prospective historical goldfields tenure at the Haunted Stream project in East Gippsland.

Shares traded at $0.008 on 2 October 2026 on volume of 1,777,578 shares, a market capitalisation of $30.11 million. The stock recorded a neutral 0.00% twelve-month return, demonstrating price stability.

Gimlet Indicated Resource Upgrade

The focal operational milestone in 2026 was completion of an updated Mineral Resource Estimate for Gimlet, successfully converting 62% of the global resource into the JORC Indicated category. This upgrade followed comprehensive infill reverse circulation and diamond drilling, confirming coherent high-grade shear-hosted gold mineralisation extending from shallow depths.

A higher proportion of Indicated resources provides greater confidence for mining studies and toll-treatment negotiations, reducing technical and financial risk in any future production decision.

Low-Capex Toll-Milling Strategy

To commercialise Gimlet without constructing expensive standalone processing infrastructure, First Au established a commercial framework with regional mill operators to evaluate toll-treatment of Gimlet ore. Multiple operating carbon-in-leach mills near Kalgoorlie hold spare milling capacity, providing a low-capital production pathway.

First Au also expanded its regional footprint through the acquisition of the Riverina East Gold Project, adding contiguous prospective greenstone tenure north of Kalgoorlie that could enhance the mining inventory available for toll-treatment.

Commercialisation and Financial Risks

Transitioning an exploration asset to production requires executing binding ore processing agreements, securing road haulage approvals, and managing contractor mining rates. Metallurgical recoveries during toll-milling campaigns may vary from resource model assumptions.

Working capital financing, ongoing corporate overheads, and fluctuations in global gold bullion prices remain the primary financial risks as First Au advances toward a production decision.
