NEW HIGH-GRADE ZONE AT EAGLEHAWK 105m @ 2.41g/t Au
HIGHLIGHTS
Drilling at the emerging Eaglehawk deposit within the Company’s flagship Side Well Gold Project has intersected 105m @ 2.41g/t Au from 95m in 25EHRC040
-
➢ The intersection, within an interpreted high-grade structure striking northwest across the mineralised corridor, includes
-
3m @ 18.85g/t Au from 102m;
-
13m @ 5.17g/t Au from 114m; and
-
6m @ 5.08g/t Au from 180m
-
➢ This appears to be the same structure controlling high grades in hole 25EHRC003 (6m @ 121.07g/t Au from 130m[1] )
-
➢ This style of “link” structure is interpreted to be analogous to those hosting high-grade lodes at Musgrave Minerals’ (now Ramelius Resources’) high-grade Break of Day deposit near Cue[2]
-
➢ This is the first link structure to be specifically targeted with holes drilled to the northeast
-
➢ Eaglehawk is currently outside the existing Side Well Global Mineral Resource Estimate (MRE) of 668,000oz at 2.8 g/t Au with the maiden resource to be included in the Global MRE Update scheduled for December 2025
-
➢ Further RC drilling is being planned immediately to confirm the extent and orientation of this zone and to target new high grade link structures and extensions
Great Boulder Resources (“ Great Boulder ” or the “ Company ”) (ASX: GBR ) is pleased to provide exploration results at the Eaglehawk deposit at the Company’s flagship Side Well Gold Project[3] (“ Side Well ”) near Meekatharra in Western Australia which hosts a MRE of 668,000oz @ 2.8 g/t Au.
Great Boulder’s Managing Director, Andrew Paterson commented:
“This is an extraordinary result at Eaglehawk. We interpreted a cross-cutting fault or structure running through the deposit towards the northwest and dipping northeast, which was interpreted to explain the extremely high-grade intersection of 6m @ 121.07g/t Au in 25EHRC003. The team drilled a hole

towards the northeast and nailed this intersection. Within the 105m of mineralisation there are discrete higher-grade intervals which appear to correspond to known west-dipping veins. There are a limited number of holes defining the structure at this stage, so we’ll be drilling more holes in the area as soon as possible to continue defining its orientation and thickness.”
“This new high-grade zone is interpreted to have structural parallels to the high-grade link structures at Musgrave Minerals’ Break of Day discovery near Cue which contained the bulk of the gold ounces in that resource.”
“This is the first link structure to be specifically targeted by Great Boulder with holes drilled towards the northeast. While we still need to confirm its dip, thickness and extent, this result is extremely exciting due to its potential to host significant high-grade ounces. We will optimise intersection angles with ongoing drilling, and as our understanding grows it will help us target other similar structures.”
Side Well Gold Project
Great Boulder’s flagship Side Well Gold Project is located in the heart of the Meekatharra gold field neighbouring Westgold Resources’ (ASX:WGX) Paddy’s Flat operation. The project hosts a current Mineral Resource Estimate (MRE) of 7.45Mt @ 2.9g/t Au for 668,000oz announced in late 2023 (Table 2) and the Company is on track to deliver an updated MRE by the end of the year. Side Well is surrounded by mining infrastructure in the rapidly growing Murchison region.

The current Side Well MRE comprises two deposits: Mulga Bill and Ironbark. This resource will be bolstered by the addition of new estimates for Eaglehawk, Saltbush and Side Well South as well as extensional and infill drilling. These five deposits make up the current Side Well Exploration Target range of 272koz to 465koz announced on 26/5/2025 which, when added to the current 685koz MRE provides a near-term expectation of achieving updated resources in the range 940koz to 1.1Moz.
TABLE 1: SIDE WELL EXPLORATION TARGET
| Tonnes (kt) | Tonnes (kt) | Grade (g/t Au) | Grade (g/t Au) | Ounces (koz) | Ounces (koz) |
|---|---|---|---|---|---|
| Lower | Upper | Lower | Upper | Lower | Upper |
| 4,800 | 5,000 | 1.8 | 2.9 | 272 | 465 |
Tonnages are rounded to 100kt; ounces rounded to 1koz. Rounding errors may occur.
The potential quantity and grade of the Exploration Target is conceptual in nature and, as such, there has been insufficient exploration drilling conducted to estimate a Mineral Resource. At this stage it is uncertain if further exploration drilling will result in the estimation of a Mineral Resource. The Exploration Target has been prepared in accordance with the JORC Code (2012).
The Company is on track to deliver an updated Side Well MRE by the end of this year which will incorporate all drilling completed by the end of September. Drilling currently underway, including this new discovery at Eaglehawk, represents future upside to be added to subsequent resource updates. New targets such as those discussed in GBR’s recent announcement of 7/11/2025 plus other areas to the south which have yet to be drill-tested provide a large pipeline of highly prospective gold targets for future resource growth.
With a large pipeline of other gold prospects, over $16 million in cash and an aggressive drilling program underway, the Side Well Gold Project is anticipated to grow very rapidly through the year ahead.
Eaglehawk
The Eaglehawk deposit is the northern extension of the high-grade Mulga Bill – Eaglehawk trend, a large intrusive-related gold system spanning more than 3km of strike. The northern end of Eaglehawk remains open along strike, with ongoing air-core (AC) drilling testing the full extent of the corridor.
Six RC holes were drilled at Eaglehawk for 1,140m, with four of the holes angled towards the northeast to intersect an interpreted northwest-trending structure. The structure had been inferred from nearby RC drilling and mineralisation wireframes, with an implied offset or termination on some gold lodes, particularly around the recent high-grade intersection recently announced in drill hole 25EHRC003 ( 6m @ 121.07g/t Au from 130m). Gold grade distribution within west dipping veins sets appears to have a high-grade control imposed by the interpreted NW fault zone. Assays have been received for three of the six holes, with the others still pending.

FIGURE 2: PLAN VIEW OF THE INTERPRETED HIGH-GRADE SPLAY AT EAGLEHAWK
Drill hole 25EHRC040 was drilled dipping at -59° towards the northeast, intersecting a continuous zone of gold mineralisation from 95m down-hole:
- 105m @ 2.41g/t Au from 95m, including 3m @ 18.85g/t Au from 102m, 13m @ 5.17g/t Au from 114m and 6m @ 5.08g/t Au from 180m.
The last 12m of the 105m intersection are 4m composite samples averaging 0.57g/t Au. These will now be re-submitted for assay in 1m intervals.
The presence of splay or “link” structures within the Mulga Bill – Eaglehawk gold system has previously been hypothesised by GBR’s technical team. The subvertical, intrusive-related gold domains are interpreted to represent an earlier mineralisation event with the west-dipping high-grade veins emplaced during a later deformation event. This system may be a structural analogue to the Musgrave Minerals Break of Day discovery near Cue, where five high-grade link structures host 85% of the gold reported in Musgrave’s November 2020 resource update.

Appendix 1 - JORC Code, 2012 Edition Table 1 (GBR Drilling, Side Well Project)
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria | Commentary |
|---|---|
| Sampling techniques | At the Side Well Project GBR has collected data from auger sampling and from AC, RC and Diamond drilling techniques. This section encompasses all four methods. RC samples are collected into calico bags over 1m intervals using a cyclone splitter. The residual bulk samples are placed in lines of piles on the ground. 2 cone splits are taken off the rig splitter for RC drilling. Visually prospective zones are sampled over 1m intervals and sent for analysis while the rest of the hole is composited over 4m intervals by taking a scoop sample from each 1m bag. Core samples are selected visually based on observations of alteration and mineralisation and sampled to contacts or metre intervals as appropriate. Once samples are marked the core is cut in half longitudinally with one half taken for assay and the other half returned to the core tray. All core is oriented in order to measure and record structural orientations. AC samples are placed in piles on the ground with 4m composite samples taken using a scoop. Any composite samples assaying 0.1g/t Au or more are re-assayed in 1m intervals. Auger samples are recovered from the auger at blade refusal depth. Auger drilling is an open-hole technique. |
| Drilling techniques | Industry standard drilling methods and equipment were utilised. Auger drilling was completed using a petrol-powered hand-held auger. |
| Drill sample recovery | Sample recovery data is noted in geological comments as part of the logging process. Sample condition has been logged for every geological interval as part of the logging process. Where water is encountered during drilling the resultant sample quality is noted as being dry, moist or wet. No quantitative twinned drilling analysis has been undertaken. |
| Logging | Geological logging of drilling followed established company procedures. Qualitative logging of samples includes lithology, mineralogy, alteration, veining and weathering. Abundant geological comments supplement logged intervals. |
| Sub-sampling techniques and sample preparation |
1m cyclone splits and 4m speared composite samples are taken in the field. Samples are prepared and analysed at ALS Laboratories Perth for RC and diamond drilling and Intertek Laboratories for the AC drilling and auger soil samples. Samples are pulverized so that each sample has a nominal grainsize of 85% passing 75 microns. Au analysis is undertaken using Au-AA26 involving a 50g lead collection fire assay and Atomic Adsorption Spectrometry (AAS) finish. For AC drilling, Au analysis is undertaken at Intertek using a 50g lead collection fire assay with ICP-OES finish (FA50/OE). Multi-element analysis is completed at both ALS and Intertek Laboratories. Digestion is completed using both 4 Acid and Aqua-regia and analysed by ICP-AES and ICP-MS (Intertek code 4A/MS48, ALS codes ME-MS61, ME-ICP41-ABC). |
| Quality of assay data and laboratory tests |
All samples are assayed by industry standard techniques: Fire assay for gold; four-acid digest and aqua regia for multi-element analysis. |
| Verification of sampling and assaying |
The standard GBR protocol is followed for insertion of standards and blanks with a blank and standard inserted per 25 for RC drilling and 40 samples for AC drilling. Field Duplicates as second cone splits are inserted within known ore zones to assess repeatability. Analysis of ME is typically done on master pulps after standard gold analysis with a company multi-element standard inserted every 50 samples. No QAQC problems were identified in the results. No twinned drilling has been undertaken. |
| Location of data points | Sample locations and mapping observations are located and recorded electronically using a handheld GPS. Coordinates are recorded in GDA94 grid in Zone 50, which is the GDA94 zone for the Meekatharra area. |

| Drill holes are positioned using the same technique. Hole collars are initially picked up after drilling using a handheld GPS. RC and Diamond hole collars are subsequently surveyed with a DGPS for greater accuracy. This accuracy is sufficient for the intended purpose of the data. |
|
|---|---|
| Data spacing and distribution |
The spacing and location of the majority of drilling in the projects is, by the nature of early exploration, variable. As each prospect advances the drill spacing is decreased until the confidence of continuity is sufficient to allow the estimation of a mineral resource. Resource classification (e.g. Inferred or Indicated) is assigned by an independent resource consultant. The spacing and location of data is currently only being considered for exploration purposes. |
| Orientation of data in relation to geological structure |
Drilling is dominantly perpendicular to regional geological trends where interpreted and practical. Wherever possible, cross sections are shown to give a visual indication of the relationship between intersection width and lode thickness. The spacing and location of the data is currently only being considered for exploration purposes. |
| Sample security | GBR personnel are responsible for delivery of samples from the drill site to the Toll Ipec dispatch centre in Meekatharra. Samples are transported by Toll Ipec from Meekatharra to the laboratories in Perth. |
| Audits or reviews | Data review and interpretation by independent consultants on a regular basis. Group technical meetings are usually held monthly with input from independent expert consultants in the fields of geochemistry, petrology, structural geology and geophysics. |
Section 2 Reporting of Exploration Results
(Criteria listed in the preceding section also apply to this section.)
| Criteria | Commentary |
|---|---|
| Mineral tenement and land tenure status |
Side Well tenement E51/1905 is a 48-block exploration license covering an area of 131.8km2 immediately east and northeast of Meekatharra in the Murchison province. The tenement is 75% owned by Great Boulder, with Zebina Minerals Pty Ltd holding a 25% free-carried interest up to a decision to mine. E51/1679 and the adjoining prospecting licences south of E5/1905 are mainly held in agreements with Mark Selga and Wanbanna Pty Ltd which give GBR an 80% interest in those tenements. P51/3361, P51/3362, P51/3358, P51,3419 and P51/3425 are 100%-owned by GBR. A full list of the Company’s tenement interests is included in each quarterly activities report available on the ASX. |
| Exploration done by other parties |
The Side Well project has a protracted exploration history but it is relatively unexplored compared to other regions surrounding Meekatharra. |
| Geology | The Side Well tenement group covers a portion of the Meekatharra-Wydgee Greenstone Belt north of Meekatharra, WA. The north-northeasterly-trending Archaean Meekatharra-Wydgee Greenstone Belt, comprises a succession of metamorphosed mafic to ultramafic and felsic and sedimentary rocks belonging to the Luke Creek and Mount Farmer Groups. Over the northern extensions of the belt, sediments belonging to the Proterozoic Yerrida Basin unconformably overlie Archaean granite-greenstone terrain. Structurally, the belt takes the form of a syncline known as the Polelle syncline. Younger Archaean granitoids have intrusive contacts with the greenstone succession and have intersected several zones particularly in the Side Well area. Within the Side Well tenement group, a largely concealed portion of the north-north-easterly trending Greenstone Belt is defined, on the basis of drilling and airborne magnetic data, to underlie the area. The greenstone succession is interpreted to be tightly folded into a south plunging syncline and is cut by easterly trending Proterozoic dolerite dykes. There is little to no rock exposure at the Side Well prospect. This area is covered by alluvium and lacustrine clays, commonly up to 60 metres thick. Subcrop exposures of laterite, mafic and ultramafic rocks are present along the eastern side of the project, however exposure of outcrop is still relatively poor. |

| Drill hole Information | A list of the drill hole coordinates, orientations and intersections reported in this announcement are provided as an appended table in the relevant announcements for each drilling program. |
|---|---|
| Data aggregation methods |
Results are reported using cut-off levels relevant to the sample type. For composited samples significant intercepts are reported for grades greater than 0.1g/t Au with a maximum internal dilution of 4m. For single metre splits, significant intercepts are reported for grades greater than 0.5g/t Au with a maximum internal dilution of 3m. A weighted average calculation may be used to allow for bottom of hole composites that are less than the standard 4m and when intervals contain composited samples plus 1m split samples. In such instances the presence of composite samples within the intersection is noted in the comments. No metal equivalents are used. |
| Relationship between mineralisation widths and intercept lengths |
The majority of drilling is conducted using appropriate perpendicular orientations for interpreted mineralisation. Stratigraphy appears to be steeply dipping to the west however mineralisation may have a different orientation. Cross sections are shown wherever possible to illustrate relationships between drilling and interpreted mineralisation. |
| Diagrams | Refer to figures in announcement. |
| Balanced reporting | It is not practical to report all historical exploration results from the Side Well project. Selected historical intercepts have previously been re-reported by GBR to highlight the prospectivity of the region, however the vast majority of work on the project has been completed by GBR and reported in ASX announcements since 14 July 2020. |
| Other substantive exploration data |
Subsequent to Doray Minerals Limited exiting the project in 2015, private companies have held the ground with no significant work being undertaken. Wanbanna Pty Ltd has done limited work consisting mainly of AC drilling around the Burke’s Reward and Golden Bracelet prospect’s further south. |
| Further work | Further work is discussed in the document. |
