First Au Limited has boosted confidence in its Gimlet Gold Project by upgrading 62% of its resource to Indicated, while streamlining its focus on Western Australian gold through the acquisition of the Barlee Project and exiting offshore assets.
- 62% of Gimlet resource upgraded to Indicated category
- Strategic exit from Liberia-based Nimba Project with NSR royalty retained
- Acquisition of 300km² Barlee Gold Project in underexplored WA greenstone belt
- High-grade drilling results underpin resource upgrade and development potential
- Successful $5.6 million capital raise with strong director participation
Gimlet Resource Upgrade Signals Development Momentum
First Au Limited (ASX:FAU) has significantly enhanced the quality of its Gimlet Gold Project resource, with 62% of the 112,900-ounce resource now classified as Indicated. This marks a major step up from the previous resource, which was entirely Inferred, boosting geological confidence and setting the stage for potential near-term development. The updated JORC Mineral Resource Estimate now stands at 1.58 million tonnes at 2.22 g/t gold.
The upgrade was driven by a comprehensive infill Reverse Circulation (RC) drilling program completed in late 2025 and early 2026, which filled gaps in the existing drill grid to improve sample density and resource continuity. High-grade intercepts underpinning the upgrade include standout results such as 4 metres at 102.06 g/t gold and 2 metres at 47.52 g/t gold, confirming the deposit’s robust mineralisation and development credentials.
The company is now advancing concept-level technical studies including metallurgical, mining, and geotechnical investigations, alongside environmental baseline work, to support future development decisions. Located within trucking distance of multiple operating mills near Kalgoorlie, Gimlet could benefit from low-capex processing options, a key consideration for advancing the project.
Portfolio Streamlining and Strategic Refocus on Western Australia
In a decisive shift, First Au has exited its offshore interests by divesting its 35% joint venture stake in the Liberia-based Nimba Gold Project. Rather than a simple sale, the company has exchanged its equity for a 2% Net Smelter Return (NSR) royalty, preserving future upside without ongoing capital commitments or operational risk. This move aligns with the company's strategy to concentrate exclusively on Western Australian gold projects, which enjoy jurisdictional certainty, regulatory transparency, and strong investor support.
Board changes have accompanied this strategic refocus, with Non-Executive Chairman Daniel Raihani transitioning to Executive Chairman and the appointment of Piers Lewis as a Non-Executive Director, bringing extensive corporate advisory experience. These adjustments aim to sharpen management’s focus on executing the WA gold strategy.
Barlee Acquisition Expands Exploration Footprint in Underexplored Greenstone Belt
Further bolstering its Western Australia portfolio, First Au has secured a binding agreement to acquire 100% of the Barlee Gold Project, a ~300km² tenure in the Marda–Evanston Greenstone Belt. This region is historically productive, with more than 2 million ounces of gold produced nearby, yet remains underexplored due to extensive transported cover and salt lake sediments.
The Barlee project offers a compelling frontier exploration opportunity, with historical aircore drilling highlighting anomalous gold, nickel, and lithium-tin geochemistry. First Au plans to apply modern exploration techniques to unlock this potential. The acquisition consideration includes $1 million in cash and $1.25 million in shares, subject to shareholder approval.
This deal significantly enlarges First Au’s footprint in a jurisdiction favoured for gold exploration, complementing its flagship Gimlet project. The company’s approach aligns with broader market trends favouring Australian-focused gold assets over offshore ventures, as seen in its recent portfolio simplification initiatives.
Capital Raising and Drill-for-Equity Program Fuel Growth
First Au completed a well-supported $5.6 million capital raise to fund its Western Australia gold strategy, including advancing exploration at Gimlet and evaluating new opportunities like Barlee. Directors participated strongly, subscribing $600,000 of the raise, signaling internal confidence in the company’s direction.
Notably, the company employed a drill-for-equity arrangement with Newcam Minerals Pty Ltd to progress the Gimlet resource drilling. This innovative funding model, executed at $0.005 per share, allowed First Au to preserve cash while rapidly advancing its high-grade gold project. Over 162 million shares were issued to Newcam under this agreement, underpinning a value-accretive drilling campaign that culminated in the recent resource upgrade.
Ongoing assay results and planned diamond core drilling will provide further insights into metallurgical characteristics and structural geology, informing subsequent development studies.
First Au’s recent activities, including the $5.6M capital raise and high-grade drilling results at Gimlet, demonstrate a clear trajectory toward unlocking value from its WA gold assets. The company’s strategic exit from offshore assets and board reshuffle have set a focused course for growth in a favoured jurisdiction.
Bottom Line?
First Au’s enhanced resource confidence at Gimlet and expanded WA footprint position it for meaningful development progress, though success hinges on forthcoming technical studies and exploration outcomes at Barlee.
Questions in the middle?
- How will ongoing metallurgical and geotechnical studies influence Gimlet’s development timeline?
- What exploration results will emerge from the underexplored Barlee project, and how might they reshape First Au’s growth prospects?
- Will the NSR royalty retained from the Nimba exit translate into future financial upside or remain a dormant asset?
