• A single line of in-fill RC drilling comprising three holes for 360 metres has been completed at the Kamperman Deposit at the 100%-owned Feysville Gold Project, with assays pending.

• A six-hole/720-metre geotechnical diamond drill ( DD ) program at Eos and Hestia has also recently been completed.

Astral Resources’ Managing Director Marc Ducler said :

“These in-fill results from the Iris Deposit are very encouraging, supporting our plans to include Iris in the upcoming Pre-Feasibility Study (PFS) for the Mandilla Project development, which remains on track for delivery in Q2 2025.

“The in-fill program was focused on the central section of the Iris Deposit, with assay results confirming a very successful in-fill test, delivering a significant number of drill intersections with gold grades above the MRE grade of 0.8g/t Au.

“Following the success of these results, planning will commence to in-fill the remainder of Iris.

“RC programs have also recently been completed at Eos, comprising 16 holes for 2,558 metres, and at Kamperman, comprising three holes for 360 metres. Assay results for both these programs are pending and will likely be reported in the New Year.

“In addition, a four-hole/1,762-metre diamond drill program has also been completed at Theia, with assays also expected in the New Year.

“The drilling effort at Mandilla and Feysville is now winding down ahead of the Christmas break, with the diamond drill rig recently completing the geotechnical programs at both Eos and Hestia.

“We expect to commence 2025 with a flood of assay results from these recently completed drill programs, with a new round of diamond drilling also scheduled to commence at Kamperman to test a number of targets to improve our understanding of the structural controls to gold mineralisation as well as collecting drill core for metallurgical and geotechnical testing.

“While not at all typical for an announcement of this type, our thoughts and condolences go out to our colleagues at both Challenge Drilling and Saturn Metals following a fatal incident on Thursday, 5 December. No amount of drill success is worth a life and the team at Astral is devastated by the loss of a colleague that we have worked closely with over the last four years.”

Astral Resources NL (ASX: AAR) ( Astral or the Company ) is pleased to report assay results for a 21hole/3,702-metre in-fill program at the Iris Deposit, part of the 100%-owned Mandilla Gold Project ( Mandilla ), located approximately 70km south of Kalgoorlie in Western Australia (Figure 1).

Figure 1 – Map illustrating the location of the Mandilla and Feysville Gold Projects.

MANDILLA GOLD PROJECT

The Mandilla Gold Project is situated in the northern Widgiemooltha greenstone belt, approximately 70 kilometres south of the significant mining centre of Kalgoorlie, Western Australia.

The area hosts world-class deposits such as the Golden Mile Super Pit in Kalgoorlie owned by Northern Star Resources Limited (ASX: NST) and the St Ives Gold Mine south of Kambalda owned by Gold Fields Limited, as well as the substantial Beta Hunt Gold Mine owned by Westgold Resources Limited (ASX: WGX).

ASX: AAR | 3

‐ Mandilla is covered by existing Mining Leases which are not subject to any third party royalties other than the standard WA Government gold royalty.

The Mandilla Gold Project includes the Theia, Iris, Eos and Hestia deposits.

Gold mineralisation at Theia and Iris is comprised of structurally controlled quartz vein arrays and hydrothermal alteration close to the western margin of the Emu Rocks Granite and locally in contact with sediments of the Spargoville Group.

Significant NW to WNW-trending structures along the western flank of the project are interpreted from aeromagnetic data to cut through the granitic intrusion. These structures are considered important in localising gold mineralisation at Theia, which has a mineralised footprint extending over a strike length of more than 1.6km.

A second sub-parallel structure hosts gold mineralisation at the Iris deposit. The mineralised footprint at Iris extends over a strike length of approximately 600 metres, combining with Theia to form a mineralised zone extending over a strike length of more than 2.2 kilometres.

At Eos, located further to the south-east, a relatively shallow high-grade mineralised palaeochannel deposit has been identified and which extends over a length of approximately 600 metres. A primary gold source is also present with further drilling required to determine both the nature and structural controls on mineralisation and its extent.

Mineralisation delineated over approximately 800 metres of strike at the Hestia deposit, located approximately 500 metres west of Theia, is associated with a shear zone adjacent to a mafic/sediment contact, interpreted to be part of the major north-south trending group of thrust faults known as the Spargoville Shear Corridor.

Locally, the Spargoville Shear Corridor hosts the historically mined Wattle Dam gold mine (266koz at 10.6g/t Au) and, further to the north, the Ghost Crab/Mt Marion mine (>1Moz).

The mineralisation at Hestia, which is present in a different geological setting to bedrock mineralisation at Theia and Iris, remains open both down-dip and along strike.

In July 2023, Astral announced a Mineral Resource Estimate ( MRE ) of 37Mt at 1.1 g/t Au for 1.27Moz of contained gold[1] for the Mandilla Gold Project.

Metallurgical testing undertaken on each of the main deposits at Mandilla – Theia, Iris, Eos and Hestia – has demonstrated high gravity recoverable gold, fast leach kinetics and exceptional overall gold recoveries with low reagent consumptions and coarse grinding[2,3] .

In September 2023, Astral announced the results of a Scoping Study for Mandilla ( Scoping Study ) which – based on a standalone project comprising three open pit mines feeding a 2.5Mtpa processing facility, producing 80 to 100koz per year, and incorporating a gold price of A$2,750 – has a Net Present Value (8% discount rate) of $442 million[4] .

IRIS RC DRILL RESULTS

The Iris Deposit hosts an MRE of 4.4Mt at 0.8g/t Au for 115koz of contained gold[6] .

Currently, 90% of the MRE is in the Inferred category. To address this, Astral designed an RC drill program to in-fill an area of 60 metres by 280 metres to a 40 metre by 20-metre drill density in the central section of the Iris Deposit.

The drill program, undertaken in November 2024, comprised 21 holes for 3,702 metres across three drill lines.

A map showing the drill hole collar locations on local area geology is presented in Figure 3.

Approximately 40 metres to the south-east, a cross-section (Section 2) that encompasses drill holes MDRC932 through to MDRC951 is set out in Figure 5 (see Figure 3 for section location).

==> picture [497 x 497] intentionally omitted <==

Figure 5 – Cross-section through Iris illustrating drill trace, assay results and geological interpretation (see Figure 3 for section location).

As illustrated through the assay results and cross-sections, the Iris in-fill program has successfully demonstrated continuity of mineralisation across the three drill lines, with 81% of holes drilled returning significant gold mineralisation (above 5-gram x metres).

Both cross-sections further support the current MRE model, which should see the Resource upgraded from the Inferred to the higher-confidence Indicated category in this 60 metre by 280 metre area.

This, in turn, will undoubtedly support the inclusion of the Iris Deposit in the upcoming Mandilla PreFeasibility Study, due in Q2 2025.

ASX: AAR | 9

With the success of this latest program, further drilling will be planned during 2025 to increase the drill density in the remainder of the Iris Deposit.

EXPLORATION UPDATE

RC drilling for 2024 has been completed, with assay results pending for the 16-hole/2,558-metre extensional program at Eos and the three-hole/360-metre in-fill program at Kamperman.

Similarly, the four-hole/1,762-metre DD in-fill program at Theia has also been completed with assay results expected in the New Year.

The 2025 drill program will commence with a DD program at Kamperman, which is designed to improve the structural understanding of the controls to gold mineralisation and to collect drill core for metallurgical and geotechnical testing.

Upon receipt of all outstanding assay results from the 2024 drill programs, MRE updates for Theia, Iris, Eos, Hestia and Kamperman will be undertaken ahead of completion of the Mandilla Gold Project PreFeasibility Study due in Q2 2025.

Appendix 2 – JORC 2012 Table 1

Mandilla Gold Project

	Section 1– Sampling Techniques and Data	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. 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
Drilling techniques	• Drill type (e.g. core, reverse circulation, open- hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face-sampling bit or other type, whether core is oriented and if so, by what method, etc).	All RC holes were drilled using face sampling hammer reverse circulation technique with a four-and-a-half inch bit. Diamond drilling was cored using HQ and NQ2 diamond bits.
Drill sample recovery	• Method of recording and assessing core and chip sample recoveries and results assessed. • Measures taken to maximise sample recovery and ensure representative nature of the samples. • Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.	Diamond drilling collects uncontaminated fresh core samples which are cleaned at the drill site to remove drilling fluids and cuttings to present clean core for logging and sampling. Definitive studies on RC recovery at Mandilla have not been undertaken systematically, however the combined weight of the sample reject and the 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).
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.

Sub-sampling techniques and sample preparation	• 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.	HQ and NQ2 diamond core was halved and the right side 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. 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 ensure representivity for photon assay. There has been no statistical work carried out at this stage.
Quality of assay data and laboratory tests	• The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established.	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 sampling has not yet been carried 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.	Senior Geology staff have 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	Drill holes have been picked up by Topcon HiPer Ga Model RTK GPS. Southern Cross Surveys were contracted to pick up all latest drilling collars.

	locations used in Mineral Resource estimation. • Specification of the grid system used. • Quality and adequacy of topographic control.	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 at Theia is a maximum of 40 x 40m. And approaching 20 x 20m within the central areas. RC Drill spacing at Hestia is 40 x40m, in the central area and is 40 x 80m to the northern edge of the deposit. Diamond drilling at Theia is at 40 - 40m to 40-80m spacing. 3 diamond holes have been drilled at the Hestia deposit, within current RC section lines. Drill hole spacing at Eos is a maximum of 40 x 40m. And approaching 20 x 20m within the central palaeochannel. NO Sample compositing was undertaken.
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.	DD-holes are typically drilled normal to the interpreted strike. Most of the current holes at Theia are drilled on a 040 azimuth with variations applied where drill-hole spacing is limited or to test particular geological concepts.
Sample security	• The measures taken to ensure sample security.	All samples taken daily to AAR yard in Kambalda West, then transported to the Laboratory in batches of up to 10 submissions
Audits or reviews	• The results of any audits or reviews of sampling techniques and data.	No audits have been carried out at this stage.

Exploration done by other parties	• Acknowledgment and appraisal of exploration by other parties.		Several programs of RC percussion, diamond and air core drilling were completed in the area between 1988-1999 by Western Mining Corporation (WMC). In early 1988 a significant soil anomaly was delineated, which was tested late 1988 early 1989 with a series of 4 percussion traverses and diamond drilling. Gold mineralisation was intersected in thin quartz veins within a shallowly dipping shear zone. 1989-90- limited exploration undertaken with geological mapping and 3 diamond holes completed. 1990-91- 20 RC holes and 26 AC were drilled to follow up a ground magnetic survey and soil anomaly. 1991-94 - no gold exploration undertaken. 1994-95 – extensive AC programme to investigate gold dispersion. A WNW trending CS defined lineament appears to offset the Mandilla granite contact and surrounding sediments, Shallow patchy supergene (20-25m) mineralisation was identified, which coincides with the gold soil anomaly. During 1995- 96 - Three AC traverses 400m apart and 920m in length were drilled 500m south of the Mandilla soil anomaly targeting the sheared granite felsic sediment contact. 1996-97 - A 69-hole AC program to the east of the anomaly was completed but proved to be ineffective due to thin regolith cover in the area. WID3215 returned 5m @7g/t from 69m to EOH. 1997-1998- 17 RC in-fill holes to test mineralisation intersected in previous drilling was completed. A number of bedrock intersections were returned including WID3278 with 4m @ 6.9g/t Au from 46m
Geology	• Deposit type, geological setting and style of mineralisation.		The Mandilla Gold Project (Mandilla) is located approximately 70km south of Kalgoorlie, and about 25km south-west of Kambalda in Western Australia. The deposit is located on granted Mining Leases M15/633 (AAR gold rights), M15/96 (AAR gold rights) and Exploration Lease E15/1404 (wholly owned by AAR). Regional Geology Mandilla is located within the south-west of the Lefroy Map Sheet 3235. It is situated in the Coolgardie Domain, on the western margin of the Kalgoorlie Terrain within the Wiluna-Norseman Greenstone Belt, Archaean Yilgarn Block. Mandilla is located between the western Kunanalling Shear, and the eastern Zuleika Shear. Project mineralisation is related to north-south trending major D29 thrust faults known as the “Spargoville Trend”. The Spargoville Trend contains four linear belts of mafic to ultramafic lithologies (the Coolgardie Group) with intervening felsic rocks (the Black Flag Group) forming a D110 anticline modified and repeated by intense D2 faulting and shearing. Flanking the Spargoville Trend to the east, a D2 Shear (possibly the Karramindie Shear) appears to host the Mandilla mineralisation along the western flank of the Emu Rocks Granite, which has intruded the felsic volcanoclastic sedimentary rocks of the Black Flag Group. This shear can be traced across the region, with a number of deflections present. At these locations, granite stockworks have formed significant heterogeneity in the system and provide structural targets for mineralisation. The Mandilla mineralisation is interpreted to be such a target. Local Geology and Mineralisation Mandilla is located along the SE margin of M15/96 extending into the western edge of M15/633. It comprises an east and west zone, both of which are dominated by supergene mineralisation between 20 and 50 m depth below surface. Only the east zone shows any significant evidence of primary mineralisation, generally within coarse granular felsic rocks likely to be part of the granite outcropping to the east. Minor primary mineralisation occurs in sediments. The nature of gold mineralisation at Mandilla is complex, occurring along the western margin of a porphyritic granitoid that has intruded

		volcanoclastic sedimentary rocks. Gold mineralisation appears as a series of narrow, high grade quartz veins with relatively common visible gold, with grades over the width of the vein of up to several hundreds of grams per tonne. Surrounding these veins are lower grade alteration haloes. These haloes can, in places, coalesce to form quite thick zones of lower grade mineralisation. The mineralisation manifests itself as large zones of lower grade from ~0.5 – 1.5g/t Au with occasional higher grades of +5g/t Au over 1 or 2 metres. Further to the west of Theia close to the mafic/sediment contact a D2 shear sub parallels the Mandilla shear. Quartz veining and sulphides have been identified within the sediments close to the contact with high mag basalt within sheared siltstones and shales. In addition to the granite-hosted mineralisation, a paleochannel is situated above the granite/sediment contact that contains significant gold mineralisation. An 800 m section of the paleochannel was mined by AAR in 2006 and 2007, with production totalling 20,573 ounces.
Drill hole information	• A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: •easting and northing of the drill hole collar •elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar • dip and azimuth of the hole • down hole length and interception depth • hole length. • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.	This Information has been summarised in Table 1 and 2 of this ASX announcement.
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 trend strikes to the north-west at about 325°, with a sub-vertical dip. However, extensive structural logging from diamond core drilling of the quartz veins within the mineralised zones shows that the majority dip gently (10° to 30°) towards SSE to S (160° to 180°). The majority of drilling is conducted at an 040 azimuth and 60° dip to intersect the mineralisation at an optimum angle. The Hestia mineralisation is associated with a shear zone striking around 350°. The drill orientation at 090 azimuth and 60° dip is optimal for intersecting the mineralisation.
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.

ASX: AAR |

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.	Additional metallurgical testing may be required as the Mandilla Gold Project is progressed from preliminary feasibility to definitive feasibility for Hestia, Iris and Eos. Additional metallurgical testing is planned for Theia to ensure adequate variability tests have been conducted.
