Highlights

First Au reported a Gimlet resource of 1.58 million tonnes at 2.22 g/t gold.
Indicated resources account for approximately 62% of Gimlet’s reported resource.
The company reported completion of maiden Reverse Circulation Drilling at First Hit in October.
Its 2026 activities included additional Western Australian project transactions.
Gimlet technical studies and potential third-party processing remain under evaluation.

First Au Limited (ASX:FAU) is an Australian minerals explorer focused on gold and base metal projects in Western Australia. Its project portfolio includes Gimlet near Kalgoorlie, Riverina East and Barlee, while 2026 announcements have also detailed drilling at First Hit and additional Acquisition activity. The company is working across resource evaluation, exploration and commercial studies rather than reporting a completed Mining development. The distinction matters because a defined mineral resource, an exploration target and a proposed processing arrangement represent different stages of project advancement.

Gimlet Resource Classification and Project Studies

At the Gimlet Gold Project, First Au Limited (ASX:FAU) reported a JORC Mineral Resource of 1.58 million tonnes at 2.22 grams per tonne gold, containing 112,900 ounces. Its company project description, referring to an announcement dated 16 April 2026, states that 62% was classified as Indicated. The Indicated component totals 1.0 million tonnes at 2.12 grams per tonne for 70,400 ounces. These measurements describe geological estimates subject to classification and technical assumptions, not ounces already mined or sold.

Gimlet is approximately 15 kilometres northwest of Kalgoorlie. The company reports both near-surface and fresh-rock mineralisation within the project area, creating the need to evaluate mining methods, ore characteristics and access to processing facilities. First Au Limited (ASX:FAU) has identified metallurgical, geotechnical, environmental and mining workstreams, along with assessment of third-party treatment opportunities. The availability of regional infrastructure does not itself confirm an operating agreement, plant capacity allocation or a commercial return.

First Hit Drilling and Broader Project Activity

October 2026 disclosures show the company directing attention to First Hit. Its investor centre lists completion of the maiden reverse circulation drilling programme on 19 October, after an earlier announcement about commencement of drilling. The completion milestone establishes that field drilling occurred, but final conclusions about mineralisation depend on published assay data and subsequent geological interpretation. Where results remain pending, it would be premature to describe the programme as a commercial discovery.

Processing Options and Operating Considerations

An important practical question for Gimlet is how ore might be treated if subsequent work supports mining. First Au's published project information identifies the presence of operating regional mills within trucking distance as a possible route for evaluating development. Third-party treatment can change the need for standalone plant infrastructure, but it also requires agreement on commercial terms, ore specifications, scheduling and responsibility for transport. No assumptions about secured processing capacity are necessary to understand the current study position.

The company's 2026 announcements also include an ore purchase agreement and Capital Structure changes. Such developments are distinct from the technical findings at Gimlet and First Hit and should be assessed on their published terms. Mineral explorers face funding requirements, variable assay outcomes, contractor availability and permitting obligations. First Au Limited (ASX:FAU) therefore has separate geological and commercial workstreams whose progress must be documented before any production expectation can be treated as established.

Key Insights

First Au Limited (ASX:FAU) has a reported resource at Gimlet with an Indicated component and continued a wider Western Australian exploration programme during 2026. The principal distinctions are between mineral estimation, field drilling and the commercial arrangements required for production. Published technical studies, completed assays and confirmed agreements provide the factual basis for assessing how those individual activities progress.
