MAIDEN INDICATED GOLD RESOURCE AT GIMLET: 62% NOW IN INDICATED CATEGORY

HIGHLIGHTS

  • Updated JORC Mineral Resource Estimate (“MRE”) for the Gimlet Project of 1.58 Mt @ 2.22 g/t Au for 112,900 oz (0.5 g/t Au cut-off)

  • 62% of the Resource now classified as Indicated (1.0 Mt @ 2.12 g/t Au for 70,400 oz), up from 100% Inferred previously

  • Upgrade driven by recent infill RC drilling (2025–2026), improving geological confidence and continuity

  • Recent drilling highlights include:

  • 5m @ 16.68 g/t Au (25GRC010)

  • 12m @ 9.77 g/t Au (25GRC043)

  • 14m @ 5.57 g/t Au (25GRC016)

  • 4m @ 7.70 g/t Au (25GRC026)

  • Results confirm high-grade zones and strong continuity within the Gimlet mineralised system

  • Upgrade to Indicated Resource unlocks a clear pathway to development , positioning the Gimlet Project for potential near-term mining studies and development assessment

  • Located within trucking distance of multiple operating mills , supporting potential low-capex development pathways

  • The Company is advancing concept-level studies, including metallurgical, mining, geotechnical and environmental workstreams, while evaluating third-party processing options in the Kalgoorlie region

First Au Limited (ASX: FAU) (“First Au”, “FAU” or “the Company”) is pleased to announce an updated JORC Mineral Resource Estimate for its 100%-owned Gimlet Gold Project, located 15 km northwest of Kalgoorlie in Western Australia (Figure 1). The updated Mineral Resource totals 1.58 Mt @ 2.22 g/t Au for 112,900 ounces at a 0.5 g/t Au cut-off grade (Table 1). Importantly, 62% of the resource has now been classified as Indicated , representing a substantial increase in confidence compared to the previous Mineral Resource estimate (refer ASX announcement dated 23 June 2021), which was entirely classified as Inferred.

This upgrade follows recent infill RC drilling, which has increased confidence in the existing MRE. This infill drilling was completed on Mining Lease M26/849 (refer ASX announcement dated 2 February 2026) and has improved geological continuity and resource definition, and provides a strong foundation for advancing the Project toward development studies.

Executive Chairman Daniel Raihani commented:

“The updated Mineral Resource at Gimlet represents an important step forward for First Au, with a substantial portion of the resource now upgraded to the Indicated category following recent drilling. Gimlet is a high-quality asset in the Eastern Goldfields, well located near existing infrastructure and with access to multiple processing options, which places us in a strong position as we begin to consider development pathways.

“Encouragingly, the recent drilling has confirmed both strong grade continuity and the presence of high-grade zones, which gives us increased confidence in the overall resource and supports progression to the next stage of evaluation.

“Our focus now shifts to advancing technical studies and evaluating development pathways, including third-party processing options, with a clear objective of defining a commercially viable development pathway for Gimlet.”

Total 0.5 1,583 2.22 112,900

The updated Mineral Resource reflects a reduction in total ounces compared to the previous estimate, primarily due to updated geological constraints and classification criteria, resulting in a higherconfidence resource base with 62% now classified as Indicated (refer to ASX announcement dated 23 June 2021).

Project Geology

The Gimlet project area is dominated by metamorphosed felsic and intermediate volcanic rocks of the Black Flag Group of the Kalgoorlie Terrane, Yilgran Craton. The Archean geology is overlain by Cainozoic sediments, including some areas covered by salt lakes, which have inhibited the effectiveness of some of the historic exploration.

Mineralisation is interpreted to be related to a NNW-SSE near-vertical structure observed in the magnetic imagery and the geological logging of the drilling. Three styles of mineralisation are recognised at Gimlet: 1) a supergene blanket within the saprolitic clays, 2) a supergene-enriched shear zone at the oxide/fresh transition zone and 3) sheared felsic to intermediate volcanic and volcanicderived sedimentary fresh rock, containing lenses of disseminated and stringer sulphides with quartz vein material.

Pyrite appears to be the dominant sulphide phase, while arsenopyrite, sphalerite and galena have also been identified in the logging. In several cases, the mineralised structures are bifurcated and can appear as several lodes. The fresh mineralised zone often shows a broader halo of disseminated pyrite with associated sericite and carbonate-quartz veining, containing lower-grade mineralisation

Drilling and Sampling

The updated MRE is comprised of First AU drilling from 2018 to 2025 and excludes any historic drill holes. First AU has completed multiple drill programs since mineralisation was first discovered in air core (AC) drilling, announced on the 8 November 2018. Full details of the drilling and sampling techniques employed are listed in the JORC Table 1 (Appendix 1).

A total of 115 holes, 14,744.5 m have been included in the MRE (Table 2 below). The majority of the drilling is Reverse Circulation (RC) or diamond (DD), with one RC hole with a diamond tail. Air core drill holes have been used to guide geological interpretation, but were not used in the estimation process.

Total 115 14,744.5

Air core drilling was completed with a face-sampling bit and drilled to blade refusal. RC drilling was completed using a 115 mm hammer face bit. Diamond drilling was completed with a HQ core diameter.

One metre RC samples were collected through a cyclone on the rig and stored individually in standard sample bags. Four metre composite samples were collected by spear method from 1 m intervals targeting a sample weight of 2-3 kg. Intervals which returned values greater than 0.2 g/t Au or below 36 m depth for RC holes had 1 m splits submitted for assay. For RC holes, the 1 m samples collected directly from the rig cone splitter were submitted. Diamond core samples consisted of quarter core (QC) of intervals ranging from 0.2 m to 1 m, depending on geological boundaries.

All samples were assayed using a 50 g charge lead collection Fire Assay with atomic absorption spectrometry (AAS) finish by ALS Kalgoorlie or Nagrom in Perth.

The entire length of all holes was geologically logged, with RC chips logged at 1 m intervals and DD holes logged to geological boundaries.

Collar Location and Survey

Collars from 2025 drilling campaigns were recorded by a qualified surveyor in MGA94 Z51 with Topcon Hiper VR, RTK GPS units. Locations were also cross-checked with a handheld GPS. RC and DD holes completed between 2018 and 2021 had collar locations surveyed using a Leica Captivate RTK GPS (Base@SSM Kalgoorlie 107). Air core collar locations were surveyed by handheld GPS in MGA94 Zone 51. Reverse Circulation and DD holes were oriented by the drill contractor using the Reflex TN14 Gyrocompass tool. Single-shot downhole surveys were completed for RC and DD holes, and most DD holes also had downhole surveys completed with a north-seeking gyro tool. The surveys produced magnetic azimuth and dip of the drill hole at least every 30 metres downhole. The majority of the drilling was angled and drilled in an easterly direction.

Quality Assurance and Quality Control

Reviews of Quality Assurance and Quality Control (QAQC) practices have been undertaken as part of the 2026 and 2021 MRE process by Widenbar and BMGS, respectively. The QAQC processes employed to monitor the sampling and assaying included:

  • Collection of 4 m composites using a PVC spear and 1 m samples through a rig-mounted cone splitter

  • The inspection of drill samples to check recovery, moisture and contamination

  • The assaying of samples using the fire assay method

  • The inclusion of certified reference standards (standards) for a range of gold grades to test the accuracy of the laboratory.

  • The inclusion of coarse and fine blanks to test for contamination at the sample preparation stage and the assaying stage

  • The collection of field duplicate samples by collecting two samples at the same time from the cone splitter to test the repeatability of the samples.

Previous QAQC reports have been reviewed by Widenbar and are considered to be in line with industry standards. Widenbar considers the database sufficient to be used in resource estimation and classified in accordance with the 2012 Edition of the 'Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves' (“ JORC Code ”).

Data Preparation and Database

All drillhole data were validated prior to the estimation process. Validation checks included:

  • Checks for duplicate collars

  • Checks for missing samples

  • Checks for downhole from-to interval consistency

  • Checks for overlapping samples

  • Checks for samples beyond hole depth

Geological Modelling

Geologically guided implicit modelling techniques in Micromine 2026.3 software were used to generate sets of sub-vertical and horizontal mineralisation wireframes. Reverse circulation, DD and AC drilling data has been used to inform the wireframes as well as geophysical data to interpret large scale faults truncating the deposit. The AC data was not used in the grade interpolation. Mineralisation domains were created using a lower cut-off of 0.3 g/t gold

A topographic surface DTM and weathering surfaces (Base of Oxidation and Top of Fresh) were based on surfaces generated for previous resource models in 2021 and 2025. These have been reviewed by Widenbar and are considered suitable for the current resource estimation.

Estimation Methodology

Original assay intervals were composited to one metre to provide consistent data for statistical and geostatistical analysis. Probability plots were used to confirm that domaining produced consistent data sets, shown in Figures 6 and 7 below.

A top cut analysis was carried out for each mineralised domain. And the following top cuts were applied:

  • Supergene lodes 10 g/t

  • • Vertical lodes 40 g/t

Details of the top cuts are presented below in Tables 3 and 4.

Bulk densities were adopted from the 2021 BMGS resource model, shown below in Table 5; these have been reviewed by Widenbar and are considered appropriate for this type of mineralisation.

Table 5. Gimlet Density values used for resource estimation

==> picture [107 x 62] intentionally omitted <==

An “empty” rock model was created using the topographic and weathering surfaces as constraints. Sub-cells to a minimum of 1.25 m by 1.25 m by 1.25 m were used to follow geological boundaries. Mineralisation wireframes were also overlaid on this model. Resource model interpolation was carried out using the Ordinary Kriging functionality in Micromine 2026.3.

Visual inspection on sections of drill hole versus block model grades confirms that Au values in the block model correspond well to Au in drill holes. An overview and detailed example is shown in Figure 8 below.

Resource Classification

The Mineral Resource has been classified in the Indicated and Inferred categories, in accordance with the JORC Code. A range of criteria has been considered in determining this classification, including:

  • Geological continuity

  • Data Quality

  • Drillhole spacing

  • Modelling techniques

  • Estimation properties including search strategy, number of informing data and average distance of data from blocks.

The resource classification methodology incorporated a number of parameters derived from the kriging algorithms in combination with drill hole spacing and continuity and size of mineralised domains. Drill hole location plots have been used to ensure that local drill spacing conforms to the minimum expected for the resource classification. Indicated material is confined to areas where resource definition drilling is 25m by 25m or less. Material outside this area is classified as Inferred.

RC recovery and metreage were assessed by
visually assessing volumes of individual bags.
Most RC samples were dry. Ground water
ingress occurred in some RC holes and was
noted, particularly at depth. A suitable RC rig
with an auxiliary compressor was used to
ensure that in most cases groundwater
interference was kept to a minimum. A
