RC DRILLING DELIVERS MORE HIGH-GRADE GOLD ASSAYS AT KAMPERMAN
Three RC holes have been drilled at Kamperman with high-grade assay results, grading up to 12.6g/t Au, returned from each of the holes, further confirming the high-grade potential of this new discovery.
HIGHLIGHTS
-
Assay results received from a three-hole, 217-metre, reverse circulation ( RC ) drilling program completed in the March Quarter, with best results including:
-
7 metres at 5.81g/t Au from 19 metres including 2 metres at 12.3g/t Au from 19 metres and 1 metre at 10.4g/t Au from 24 metres in hole FRC263;
-
8 metres at 2.04g/t Au from 32 metres including 1 metre at 12.6g/t Au from 39 metres in hole FRC264; and
-
12 metres at 2.12g/t Au from 69 metres to end-of-hole (EOH) in hole FRC265.
-
Of the 16 holes drilled at Kamperman since January 2023, significant high-grade results have now been returned from ten of those holes.
-
Five lines of air-core ( AC ) drilling were also completed across the western portion of the Feysville tenement package.
-
A follow-up 19-hole, 2,459 metre RC in-fill and extensional drill program has also recently been completed for which assays are pending.
Astral Resources’ Managing Director Marc Ducler said : “The recent Kamperman discovery within our Feysville Project continues to deliver for Astral Resources.
“On 15 January, we mobilised an air-core rig to site to complete a five-line regional aircore program targeting potential structures in the untested north-western portion of our tenement holding.
“Following completion of the program the same drill rig was converted to an RC configuration to complete 217 metres of drilling in three holes to assist with our interpretation and modelling of the recent high-grade Kamperman discovery.
“This three-hole program yielded high-grade assay results in every hole, further reinforcing the exceptional high-grade potential at Kamperman.
“A follow-up 2,459 metre RC program was immediately completed at Kamperman with assay results expected later this quarter as we continue to unlock the potential of this growing prospect which we have increasing confidence can contribute potential future high-grade satellite ore feed to our broader Mandilla Gold Project development.”

FEYSVILLE GOLD PROJECT
The Feysville Gold Project is located within the north-north-west trending Norseman-Wiluna Greenstone Belt, within the Kambalda Domain of the Archaean Yilgarn Craton.
Feysville hosts a Mineral Resource Estimate ( MRE ) of 3Mt at 1.3g/t Au for 116koz of contained gold[1] at the Think Big deposit, providing a foundation to potentially become a source of satellite ore feed to a future operation based on the Company’s flagship Mandilla Gold Project.
Significant gold and nickel mineralisation occurs throughout the belt, including world-class deposits such as the Golden Mile Super Pit in Kalgoorlie owned by Northern Star Limited (ASX:NST) and the St Ives Gold Mine south of Kambalda owned by Gold Fields Limited.
Locally, Feysville has been interpreted to contain upthrust ultramafics, emplaced within a sequence of volcanic sediments (the Black Flag sediment group), granitic intrusions, mafic basalts, gabbro and andesite.
A map identifying tenements and deposits/prospects on local area geology is set out in Figure 2.
FEYSVILLE EXPLORATION UPDATE
In January, Astral completed a 67-hole (2,248 metre) AC drill program on prospecting licences P26/4351 to P26/4353 within the Feysville Gold Project.
The AC program, planned to achieve an aggregate 2,500 drill metres, was designed to investigate previously untested low-order magnetic structural targets and a historic soil anomaly in the northwestern portion of the tenement package.
The location of the five drill lines of AC drilling are set out in Figure 3.
No significant assays were reported from this program.
As the AC program was completed early, and for less than the planned metreage, the drilling rig was converted to an RC configuration to drill three high-priority holes (217 metres) on the new high-grade Kamperman discovery to assist with ongoing geological interpretation (Figure 4 below).
This short program was spectacularly successful, with high grade assays reported in all holes as described below.
This announcement reports assay results from this three-hole program.
An additional follow-up RC drill program has already been completed with assay results pending.

KAMPERMAN REVERSE CIRCULATION DRILLING RESULTS
New RC hole FRC263 was drilled to test up-dip from FRC243 and was collared 25 metres to the east of that hole.
Previously, FRC243 returned a best intersection of 5 metres at 8.29g/t Au[2] from 53 metres and 4 metres at 94.84g/t Au[2] from 77 metres.
-
RC hole FRC263 returned a best intersection of:
-
7 metres at 5.81g/t Au from 19 metres including 2 metres at 12.3g/t Au from 19 metres and metre at 10.4g/t Au from 24 metres.
New RC hole FRC264 was drilled to test up-dip of FRC241 and was also collared 25 metres further to the east of that hole.
Previously, FRC241 returned a best intersection of 21 metres at 4.16g/t Au[3] from 31 metres.
RC hole FRC264, which was only drilled to a depth of 55 metres after encountering excessive water, returned a best intersection of:
- 8 metres at 2.04g/t Au from 32 metres including 1 metre at 12.6g/t Au from 39 metres.
New RC hole FRC265 was drilled to test up-dip of FRC240 and was collared 25 metres further to the east of that hole.
Previously, FRC240 returned a best intersection of 35 metres at 2.19g/t Au[3] from 81 metres.
-
RC hole FRC265 returned a best intersection of:
-
12 metres at 2.12g/t Au from 69 metres to end-of-hole (EOH).
RC hole FRC265 ended in gold mineralisation. Given the current understanding of the geometry of the mineralisation, this was anticipated to occur.
A cross-section of Kamperman which includes FRC265 is set out in Figure 5.
As illustrated, gold mineralisation is interpreted to be associated with a package of north-north-west trending shears within an intermediate to felsic porphyry unit. Mineralisation remains open down-dip and along strike.
At Kamperman, gold intercepts are routinely high-grade with significant occurrences of coarse gold observed in earlier drilling. When combined with previously identified targets and existing Mineral Resources on the Project, the Company believes the Feysville Project has very real potential to contribute significant future high-grade ore sources to the greater Mandilla Gold Project subject to ongoing development studies.

Appendix 2 – JORC 2012 Table 1
Feysville
Section 1 – Sampling Techniques and Data
| Criteria | JORC Code Explanation | Commentary |
|---|---|---|
| Sampling techniques | • Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. |
The project has been sampled using industry standard drilling techniques including diamond drilling (DD), and reverse circulation (RC) drilling and air-core (AC) drilling. The sampling described in this release has been carried out on the 2024 AC and RC drilling. The RC holes were drilled and sampled. The samples are collected at 1m intervals via a cyclone and splitter system and logged geologically. A four-and-a-half-inch RC hammer bit was used ensuring plus 20kg of sample collected per metre. All RC samples were collected in bulka bags in the AAR compound and trucked weekly to ALS in Kalgoorlie via Hannans Transport. All samples transported were submitted for analysis. Transported material of varying thickness throughout project was generally selectively sampled only where a paleochannel was evident. All samples were assayed by ALS with company standards blanks and duplicates inserted at 25 metre intervals. The AC holes were drilled and sampled AC – 1m samples were collected from individual 1m sample piles. AC – 3-4m composite samples were collected from individual 1m sample piles. The last metre for each hole was collected as a 1m sample. Sample weights were between 2 and 3 kg. . All AC samples were collected in bulka bags in the AAR compound and trucked weekly to ALS in Kalgoorlie via Hannans Transport. All samples transported were submitted for analysis. All samples were assayed by ALS with company standards blanks and duplicates inserted at 25 metre intervals. Historical - The historic data has been gathered by a number of owners since the 1980s. There is a lack of detailed information available pertaining to the equipment used, sample techniques, sample sizes, sample preparation and assaying methods used to generate these data sets. Down hole surveying of the drilling where documented has been undertaken using Eastman single shot cameras (in some of the historic drilling) and magnetic multi-shot tools and gyroscopic instrumentation. All Reverse Circulation (RC) drill samples were laid out in 1 metre increments and a representative 500 – 700 gram spear sample was collected from each pile and composited into a single sample every 4 metres. Average weight 2.5 – 3 kg sample. All Aircore samples were laid out in 1 metre increments and a representative 500 – 700 gram spear sample was collected from each pile and composited into a single sample every 4 metres. Average weight 2.5 – 3 kg sample. 1m samples were then collected from those composites assaying above 0.2g/t Au. |

sample collected indicated recoveries in the high nineties percentage range. Poor recoveries are recorded in the relevant sample sheet. No assessment has been made of the relationship between recovery and grade. Except for the top of the hole, while collaring there is no evidence of excessive loss of material and at this stage no information is available regarding possible bias due to sample loss. RC: RC face-sample bits and dust suppression were used to minimise sample loss. Drilling airlifted the water column above the bottom of the hole to ensure dry sampling. RC samples are collected through a cyclone and cone splitter, the rejects deposited on the ground, and the samples for the lab collected to a total mass optimised for photon assay (2.5 to 4 kg). Poor recoveries are recorded in the relevant sample sheet. AC samples are collected through a cyclone, the rejects deposited on the ground, and the samples for the lab collected. |

| Logging | • Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. • Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. • The total length and percentage of the relevant intersections logged. |
All chips and drill core were geologically logged by company geologists, using their current company logging scheme. The majority of holes (80%+) within the mineralised intervals have lithology information which has provided sufficient detail to enable reliable interpretation of wireframe. The logging is qualitative in nature, describing oxidation state, grain size, an assignment of lithology code and stratigraphy code by geological interval. RC: Logging of RC chips records lithology, mineralogy, mineralisation, weathering, colour and other features of the samples. All samples are wet-sieved and stored in a chip tray. AC samples were logged for colour, weathering, grain size, lithology, alteration veining andmineralisation where possible |

• If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. • Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled. |
RC holes were drilled and sampled. The samples are collected at 1m intervals via a cyclone and splitter system and logged geologically. A four- and-a-half inch RC hammer bit was used ensuring plus 20kg of sample collected per metre. AC samples are collected through a cyclone, the rejects deposited on the ground, and the samples for the lab collected in pre-numbered calico bags. Wet samples are noted on logs and sample sheets. Historical - The RC drill samples were laid out in one metre intervals. Spear samples were taken and composited for analysis as described above. Representative samples from each 1m interval were collected and retained as described above. No documentation of the sampling of RC chips is available for the Historical Exploration drilling Recent RC drilling collects 1 metre RC drill samples that are channelled through a rotary cone-splitter, installed directly below a rig mounted cyclone, and an average 2-3 kg sample is collected in pre-numbered calico bags, and positioned on top of the rejects cone. Wet samples are noted on logs and sample sheets. Standard Western Australian sampling techniques applied. There has been no statistical work carried out at this stage. ALS assay standards, blanks and checks were inserted at regular intervals. Standards, company blanks and duplicates were inserted at 25 metre intervals. RC: 1 metre RC samples are split on the rig using a cone-splitter, mounted directly under the cyclone. Samples are collected to 2.5 to 4kg which is optimised for photon assay. Sample sizes are appropriate to the grain size of the material being sampled. Unable to comment on the appropriateness of sample sizes to grain size on historical data as no petrographic studies have been undertaken. Sample sizes are considered appropriate to give an indication of mineralisation given the particle size and the preference to keep the sample weight below a targeted 4kg mass which is the optimal weight to |

Photon Assay technique at ALS, Kalgoorlie. Samples submitted for analysis via Photon assay technique were dried, crushed to nominal 90% passing 3.15mm, rotary split and a nominal ~500g sub sample taken (AC/RC Chips method code CRU-32a & SPL- 32a, DD core method codes CRU-42a & SPL-32a) The ~500g sample is assayed for gold by PhotonAssay (method code Au- PA01) along with quality control samples including certified reference materials, blanks and sample duplicates. The ALS PhotonAssay Analysis Technique: - Developed by CSIRO and the Chrysos Corporation, This Photon Assay technique is a fast and chemical free alternative to the traditional fire assay process and utilizes high energy x-rays. The process is non-destructive on and utilises a significantly larger sample than the conventional 50g fire assay. ALS has thoroughly tested and validated the PhotonAssay process with results benchmarked against conventional fire assay. The National Association of Testing Authorities (NATA), Australia's national accreditation body for laboratories, has issued Min Analytical with accreditation for the technique in compliance with TSO/TEC 17025:2018- Testing. Certified Reference Material from Geostats Pty Ltd submitted at 75 metre intervals approximately. Blanks and duplicates also submitted at 75m intervals giving a 1:25 sample ratio. Referee samplinghasnot yet beencarried out. |
| Verification of sampling and assaying |
• The verification of significant intersections by either independent or alternative company personnel. • The use of twinned holes. • Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. • Discuss any adjustment to assay data. |
Geology Manager or Senior Geologist verified hole position on site. Standard data entry used on site, backed up in South Perth WA. No adjustments have been carried out. However, work is ongoing as samples can be assayed to extinction via the PhotonAssay Analysis Technique |
| Location of data points |
• Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. • Specification of the grid system used. • Quality and adequacy of topographic control. |
Drill holes have been picked up by Topcon HiPer Ga Model RTK GPS. Southern Cross Surveys were contracted to pick up all latest RC drilling collars. Historical hole collar locations and current AC drill holes were recorded with a handheld GPS in MGA Zone 51S. RL was initially estimated then holes, once drilled were translated onto the surveyed topography wire frame using mining software. These updated RL’s were then loaded into the database. Grid:GDA94 Datum MGA Zone 51 |
| Data spacing and distribution |
• Data spacing for reporting of Exploration Results. • Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. • Whether sample compositing has been applied. |
RC Drill hole spacing varies from 40x20m to 40x80m spacings. AC spacing is generally at 200m with some areas down to 100m. Diamond drilling has been used to test depth extensions and stratigraphy and is not on any specific grid pattern. NO Sample compositing was undertaken for RC samples. AC samples were composited to a maximum of 4m. The EOH sample was collected as a1msample aswellas areas ofgeological interest. |
| Orientation of data in relation to geological structure |
• Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. • If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
Diamond and RC drill holes have been drilled normal to the interpreted geological strike or interpreted mineralised structure. The drill orientation will be contingent on the prospect mineralistion location and style. AC drilling was oriented 60 degrees toward MGA east (090) and is based on local geology and alignment of the drilling targets. |

Previous exploration by WMC Resources Ltd targeted gold and nickel with initial focus on the ultramafic unit for nickel sulphides, with best results of 2m @ 1%Ni and 1m @ 2.2%Ni. Exploration has consisted of a comprehensive soil survey, 264 RAB / Aircore holes, 444 RC holes and 5 diamond holes. The soil survey defined an area of extensive gold anomalism clustered in the SE corner of the tenement package. Follow- up drilling confirmed the gold potential of the area with intersections such as 7m @ 2.47g/t Au at Empire Rose, 10m @ 9.1g/t Au at Ethereal, 8m @ 2.08g/t at Kamperman and 8m @ 3.26g/t Au at Rogan Josh. |

| Geology | • Deposit type, geological setting and style of mineralisation. |
TheFeysvilleproject is located 16km SSE of Kalgoorlie. The project is situated in the geological / structural corridor, bounded by the Boulder Lefroy Fault, that hosts the world class plus million ounce deposits of Mt Charlotte, Fimiston, New Celebration, Victory-Defiance, Junction, Argo and Revenge / Belleisle. and St Ives. Regional Geology Geology at Feysville is complex with regional mapping identifying a double plunging northwest trending antiformal structure known as the Feysville Dome bounded to the west by the Boulder Lefroy Fault and south by the Feysville Fault. The Feysville fault, located on the southern margin of the tenement is interpreted to represent thrusting of underlying mafic/ultramafic volcanic and intrusive rocks over a younger felsic metasedimentary sequence to the south. The sequence has been extensively intruded by intermediate and felsic porphyries. Local Geology and Mineralisation There a number of historical gold workings on the project and drilling has identified strong alteration associated with primary gold mineralisation. Gold mineralisation is typically located at the sheared contacts of intrusive porphyry units, within pyrite sericite altered porphyries and also associated with chalcopyrite magnetite/epidote altered breccia zones within ultramafic units. |

| Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
||
|---|---|---|
| Data aggregation methods |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. • The assumptions used for any reporting of metal equivalent values should be clearly stated. |
No data aggregation methods have been used. A 100ppb Au lower cut off has been used to calculate grades for AC drilling A 0.3g/t Au lower cut off has been used to calculate grades for RC drilling, with maximum internal dilution of 5m. A cutoff grade of >0.5g*m has been applied for reporting purposes in the tables of results. This has not been applied. |
| Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’). |
The overall mineralisation trends have been intersected at an appropriate angle to form the closest intercept length to true width. The results are reported as downhole depths. |
| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported. These should include, but not be limited to a plan view of drill hole collar locations and appropriate _sectional views. _ |
Please refer to the maps and cross sections in the body of this announcement. |
| Balanced reporting | • Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
Balanced reporting has been applied. |
| Other substantive exploration data |
• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
No other substantive exploration data. |
| Further work | • The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
Follow up, Reverse Circulation & Diamond Drilling is planned. No reporting of commercially sensitive information at this stage. |
