ASX Announcement 25 October 2024
The Eureka Gold Project has a JORC Mineral Resource Estimate of 112,000oz at 1.42g/t at a cut-off grade of 0.5g/t. This includes an Indicated Mineral Resource Estimate of 62,000oz. The Project acquisition comprises four mining licences M24/0584, M24/0585, M24/0586 and M24/0189, one miscellaneous licence L24/0234 and the three prospecting licences P24/5116, P24/5549 and P24/5548 (the Tenements ).
Eureka was mined in the early 1990’s and then subject to tribute mining in 2018. The majority of the gold resource is currently hosted on granted mining leases in the immediate vicinity of the Eureka open pit, along strike and down-dip. The mineralisation is hosted within several steeply dipping sheared zones dipping at approximately 75 degrees to the east.
Resource drilling in 2021 by Delta (formerly TNT Mines Ltd) (ASX Announcement 28 July 2021: New Gold Lode at Eureka, ASX Announcement 7 October 2021: Eureka North Exploration Results Include High Grade Gold) led to the establishment of a new lode to the north of the pit. The successful drilling campaign confirmed additional mineralisation in addition to historical results in the ASX release including:
-
4m @ 134.52g/t Au from 53m from drillhole ERC39, and
-
4m at 32.08g/t Au from 104m from Drillhole WRRC106.
-
Drilling to the south of the pit extended the known mineralisation with additional high grade results including:
-
6m at 13.88g/t from 38m, including 2m at 31.95g/t from drillhole WRRC0121.
Subsequent extensional drilling in 2021 by Delta (formerly Red Dirt Metals Ltd) at Eureka North resulted in more significant results (ASX Announcement 7 October 2021: Eureka North Exploration Results Including High Grade Gold). Significant assays returned include:
-
3m @ 48.75 g/t Au from 129m in WRRC0135
-
4m @ 11.2 g/t Au from 32m in WRRC0136 (within 4m composite), and
-
1m @ 5.97 g/t Au from 108m in WRRC0127
Under the terms of the acquisition, Javelin will acquire from Delta 100% of the issued capital in Warriedar Mining Pty Ltd ( Warriedar ), a wholly owned subsidiary of Delta which owns 100% of the Eureka Project, for the following total acquisition consideration payable to Delta at settlement:
-
$1,500,000 in cash (from the proceeds of the $3m capital raising);
-
$1,500,000 worth of Shares, being 500,000,000 fully paid ordinary shares in Javelin ( Shares ), at a deemed issue price of $0.003 per Share, subject to shareholder approval. These shall be subject to 12 months voluntary escrow from their date of issue; and
-
$1,000,000 worth of deferred consideration Shares at a deemed issue price equal to the 10-day volume weighted average price ( VWAP ) of Shares as traded on the ASX up to and including the day prior to the relevant vesting date, subject to shareholder approval. The deferred consideration shares will vest upon the achievement of the earlier of:
-
the recommencement of mining operations on one or more of the Tenements; or
-
Javelin increasing the JORC compliant Inferred Mineral Resource across the Tenements to >200,000oz at a 0.5% g/t cut off, provided that the relevant milestone has been satisfied within the earlier of 3 years of settlement of the acquisition and 15 December 2027.
Delta will also have the right to appoint a representative to the Board of Javelin upon settlement of the acquisition.

ASX Announcement 25 October 2024
The Eureka acquisition will deliver Javelin its second brownfields exploration project in WA’s Eastern Goldfields. The Company already owns the Coogee Project, where it is set to commence drilling this quarter. The Coogee Project is located next to the rich St Ives Goldfield and has a JORC Resource of 126,685oz of gold and 4,133 tonnes of contained copper (ASX Announcement 26 August 2024: 158% Increase in Coogee Gold MRE) (Appendix 2).
Javelin Executive Chairman Brett Mitchell said: “Eureka is an outstanding acquisition opportunity which has become available only because Delta is focussed on a wider Lithium strategy.
The Project meets our strategy perfectly. It has an established resource with further known mineralisation which remains open at depth and along strike. And like Coogee, it has been exposed to virtually no modern exploration.
Javelin now has two compelling brownfields exploration projects on mining leases, 50km either side of Kalgoorlie with immense exploration upside, giving us huge opportunities to create value for shareholders with further exploration”.

Background on the Eureka Gold Project
The Eureka Gold Project tenements are located in the Eastern Goldfields of WA, 54 km north-north-west of Kalgoorlie and is accessed via the Goldfields Highway, Figure 2.
The region is considered prospective for gold mineralisation and contains a number of historical mines and mineral occurrences. The Project is situated in a highly fertile greenstone belt with numerous gold deposits and abundant gold occurrences nearby.
Page 3
ASX Announcement 25 October 2024
The Eureka gold deposit was first discovered in the 1890s, with historical underground mining worked until 1940. Historical information sources noted that gold mineralisation is associated with shearing and quartz veining within easterly dipping oxidised fine grained mafic rocks. Recorded production from 1897 up to 1940 totalled 809 tonnes averaging 27.8 g/t Au. From 1985 to 1988, mining of the Eureka open pit included 220,000 tonnes at 4.5 g/t Au for 32,000oz by West Coast Holdings Limited. Development to test for underground mineralisation potential at Eureka was started in mid-1996. In 2018, Tyranna Resources Limited also mined 50,600 tonnes of ore grading 3.16 g/t Au producing 5,374oz of gold.

ASX Announcement 25 October 2024
Geology and Prospectivity
Regionally, the Eureka gold deposit occurs on the eastern limb of the major south-east plunging GoongarrieMt. Pleasant Anticline. The eastern limb consists predominantly of north-north-west trending mafic and ultramafic lithologies. This zone consists of multiple shear zones occurring within intercalated felsic, mafic and ultramafic lithologies in the vicinity of the synformal axis. The Eureka gold deposit is located within the Bardoc Tectonic Zone which hosts the Paddington and Bardoc gold deposits.
Gold mineralisation at Eureka occurs as a number of lens-shaped ore shoots up to 10m wide within the shear zone. The gold is hosted in quartz veins and quartz stringers within the altered mafic host rocks. The mineralisation at Eureka is hosted within basalts and is contained with a zone of shearing and foliation with quartz veining containing quartz, carbonate and low amounts of sulphides with some visible gold has a variable thickness of up to 20 metres. Mineralisation has been exploited in a 120m deep, 300m long open pit that was developed on a number of lens-shaped shoots up to 10 metre wide within an intensely sheared zone approximately 30 metres wide. The mineralisation is sub-vertically dipping and strikes in a north south orientation with several offsets and splays forming the main structure.

Eureka Gold Project Mineral Resource Estimate
The existing Eureka Gold Project Mineral Resource Estimate ( MRE ) stands at 2.45Mt at 1.42 g/t Au totalling 112,000 ounces of gold . Table 1 shows the Eureka Mineral Resource Estimate as of June 2021 based on tonnes and grades (also refer to Appendix 3 – Summary of JORC Table 1 and Listing Rule 5.8.1).
Table 1 : Eureka Gold Deposit Mineral Resource Estimate by Classification as of June 2021 (at a 0.5 g/t Au cut-off)
| Classification | Tonnage t |
Grade g/t Au |
Contained Metal (Oz Gold) |
|---|---|---|---|
| Indicated | 1,269,000 | 1.53 | 62,000 |
| Inferred | 1,183,000 | 1.3 | 50,000 |
| Total | 2,452,000 | 1.42 | 112,000 |
Exploration Potential
Strike potential north of the pit
Some 750m of strike north of the pit remain inadequately tested, which will be the focus of the planned Eureka exploration drilling program in early 2025. The previous exploration may have been ineffective as most of the drillholes were terminated at shallow depths thus not penetrating the zone of near-surface leaching. The drill traverses were restrictive in coverage and potentially have missed the best target zones.
Significant RC drilling results immediate north of the pit include:
-
ERC39: 4m @ 135 g/t Au from 53m
-
WRRC0106: 4m @ 32.6 g/t Au from 104m, including 1m @ 116 g/t Au from 104m
-
WRRC0019: 4m @ 11 g/t Au from 42m, including 2m @ 19.2 g/t from 43m
-
WRRC0135: 3m @ 48.75 g/t Au from 129m
-
WRRC0136: 4m @ 11.2 g/t Au from 32m
The full results are set out in Appendix 1.
Strike potential south of the pit
At surface, the main host structure strikes over the western boundary of the leases some 330m south of the pit. Due to the east dip of the host structure, the 200m strike length seen at surface extends at depth beneath the tenement.
Significant RC drilling results immediate south of the pit include:
-
WRRC0001: 13m @ 2.22 g/t Au from 51m
-
WRRC0121: 6m @ 13.88 g/t Au from 38m
-
WRRC0081: 13m @ 2.13 g/t Au from 110m, 9m @ 3.15 g/t Au from 127m, including 3m @ 7.9 g/t Au from 131m
-
WRRC0082: 3m @ 8.59 g/t Au from 74m
The full results are set out in Appendix 1.
Strike potential for parallel structures extends some 4,400m south of the pit. This zone remains poorly tested with all the drilling concentrating around the Eureka Pit.

Potential at depth beneath the underground resource
The mineralised veins have been drilled over 180 vertical metres below the bottom of the current pit. Deeper drilling is suggested to test the continuation of the subvertical east dipping gold mineralised zone. The northern zone along with the bottom of the pit remain open.

JORC CODE, 2012 EDITION – TABLE 1 REPORT – APPLICABLE TO EUREKA
Section 1 Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques | Nature and quality of sampling (eg 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. |
Historic drilling by various companies included reverse circulation (RC) drill samples which were collected and split in even metre intervals when sample was dry. Wet samples were speared or on occasion scoop sampled. RC drill chips from each metre were examined visually and logged by the geologist. Duplicate samples were collected at 1 m intervals by scoop sampling reject bags. Based on the historical drilling reviewed from Javelin through WAMEX files, drilling commenced from 1982, which included Vacuum, Augur, open hole percussion/ RAB, RC and diamond core drilling (mostly NQ, also PQ and HQ). Sampling methods included chip samples collected and split in even 1 metre or 4 metre composite intervals for dry samples. Wet samples were speared or on occasion scoop sampled. Diamond core was half core sampled at selected intervals where the geologist recorded Samples are collected from rig mounted cyclone cone splitter at 1m intervals. Duplicate samples are collected from reject bags every 10m (by spear sampling). Calico samples are weighed to ensure minimum size of 2.5kg are collected. Current QAQC protocols include the analysis of field duplicates and the insertion of appropriate commercial standards (I, e., certified reference material (CRM). Sample protocols where they are described from historical reports sourced from WAMEX followed by historic operators are in line with industry standards at the time. RC drilling was used to obtain 1 m samples from which a 1 m samples (mineralisation zones) or 2m and 4m composite samples (waste zones) of approximately 2.5 to 5kg was also collected. |
| 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). |
For the 2020-2021 drilling the RC rig specs are as follows: Schramm T450 RC rig - 5 ½ inch diameter face sampling hammer LC36 KWL700 RC rig (for deep holes) – 5 inch face sampling hammer X350 RC rig - 4 ½ inch diameter face sampling hammer; drilling since May 2021) Historically, the project has been drilled using rotary air blast (RAB), percussion (Perc), reverse circulation (RC) and diamond core drilling (DD) over numerous campaigns by several companies. The majority of holes are on a grid either infilling within or surrounding historical pit and underground (UG) workings or extending along strike into geochemical or geophysical (areo-mag) anomalies. The recent programs drilled in 2020 and 2021 have all been RC drilling. The majority of drill holes have a dipof -55 or - 60° and azimuths mostlydrilled to |

| 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. |
RC sample recovery is visually assessed and recorded in drill logs. RC drilling programs showed good recoveries. From WAMEX records, descriptions noted that the majority of DD drilling had good recoveries >90%, although several holes recorded recoveries of ~50% or lower within highly fractured quartz vein intervals, and also where there was intersection of historical UG workings. RC samples were visually checked for recovery, moisture, and contamination. A cyclone and splitter were used to provide a uniform sample and these were routinely cleaned. Wet samples and logged barren zone, 4 m composites were speared to obtain the most representative sample possible. Sample recoveries are mostly high with only a very small number of wet samples recorded by geologists. No significant sample loss has been recorded with a corresponding increase in Au present. No sample bias is anticipated, and no preferential loss/gain of grade material has been noted |
| 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. |
RC chips are geologically logged at 1 metre intervals. RC chip trays have been stored for future reference. Detailed logging exists for more recent drilled prior to WRD holes (18EKDD, and 19ERC prefix holes, but most of the historical RC and DD holes drilled do not have the logging digitally recorded in WRD database files provided, although the WAMEX files do contain PDF copies of RC and DD geology logs WRD RC chip logging included the recording of colour, lithology, regolith, oxidation state, colour, alteration, mineralisation, and veining/quartz content. The entire length of each hole was logged. Previous RC and DD drilling completed by previous owners contained similar detailed geological descriptions in PDF logs. Remaining core was examined from the 18EKDD drilling program at the Eureka project field office. The core remaining is in good condition but has been poorly labelled, with intervals and hole identification often indistinguishable as no aluminium tags or more permanent markers were used on core blocks or to label the core trays. Percentage of drilling logged that was used in the 2021 MRE are record as follows: • 2020-21 RC drilling – WRRC holes = 96% logged, abandoned holes not logged records in WRD DB • 19ERC prefix – RC drilling 93% logged records in WRD DB • 18EKDD – RC/DD drilling88% logged |

| 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. |
Previous companies have conducted diamond drilling; WAMEX records have noted that ½ core sampling was mostly conducted, generally in highly selective intervals based RC chips were collected from rig mounted cyclone cone splitter as 1m samples. 2 and 4m composites using a sample scoop were taken from the 1m RC plastic sample bags. Samples were generally dry. 1m RC samples are also speared. At the commercial laboratory, RC samples are dried at minimum 60° C. If the sample weight is greater than 3 kg, the sample is riffle split. It is then pulverised to a grind size where 85% of the sample passes 75 micron. Field QAQC procedures included the insertion of CRMs and field duplicates for RC drilling after every 10 samples. CRMs represented approximately 5% of total samples. Field duplicates were collected during the RC drilling programs in 2020-21. Duplicate samples are submitted at a rate of one duplicate submitted for every 10 samples. Duplicates samples represent approximately 5% of total samples. Based on statistical analysis of the field duplicate results, there is no evidence to suggest the samples are not representative. A sample size of between 2.5 and 5 kg was collected. This size is considered appropriate, and representative of the material being sampled given the width and continuity of the intersections, and the grain size of the material being collected. |
| 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) |
Both single 1 metre samples and 2 m or 4 m composite samples have been analysed using a 30g fire assay technique with an AAS finish. No geophysical tools etc. have been used at Eureka. Field QAQC procedures include the insertion of both field duplicates and CRMs. No blanks were inserted by TIN. Assay results to date have been satisfactory and demonstrate an acceptable level of accuracy and precision. Laboratory QAQC involves the use of internal certified reference standards, blanks, splits, and replicates. Analysis of these results to date show an acceptable level of precision and accuracy. |

| 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. |
All significant intersections were assessed by Javelin Minerals through current access and historical databases. Version 2024 Micoomine has been used to delineate gold grades above 0.5 g/t Au level from the Javelin geologist as part of the over verification of assay results comparing to the historically significant intersections previously reported. No specific twinned holes have been drilled to date. Recent drilling from 2018 to the current programs have some infill holes in close proximity to historical drilling, and mostly confirm the presence of Au mineralisation, and also intersect significant mineralisation where historical hole intervals that were not sampled. Field data and logging is collected and entered using Toughbook field computers. The data is sent via a SharePoint site, to a contract database administrator for validation and compilation into an MS Access database. No adjustments have been made to assay data apart from values below the detection limit which are assigned a value of negative the detection limit for the 2021 MRE work. |
| 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. |
All recently drilled hole collars have been surveyed by hand- held GPS (Garmin 64 GPS) to an accuracy of about 3m. The drill holes are then picked up using a DGPS by Cardno Spectrum Survey, Kalgoorlie at the completion of each drill program. Downhole surveying is conducted by the drilling contractor, using EZ-Shot single shot downhole camera at 30 m intervals at the completion of each hole The grid system is MGA_GDA94 Zone 51. Topographic datum is AHD71(Australian Height Datum 1971). The topographic surfaces include a very high resolution DTM surface (LiDAR survey) was initially used for hole collar location verification. Part of the project area that was not covered by the DTM surfaces was validated or edited using the collar coordinates based on DGPS surveys. |
| 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. |
Historical exploration and drilling at Eureka targeted discrete areas based on surface geochemical and geophysical anomalies, historical workings that identified the location of host mineralisation. Consequently, current drilling is not grid based, but across the historical open pit and UG workings the drill spacing is nominally 10m N x 10m E. Extensions to the north and south have been nominally drilled at 20m N x 20m/10m spaced drilling. The mineralised domains have sufficient continuity in both geology and grade to be considered appropriate for the Mineral Resource and Ore Reserve estimationprocedures |

| and classification applied under the 2012 JORC Code 4m composite samples were collected from RC drill holes within the logged barren intervals |
||
| 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. |
Drill hole collars are set-out on the MGA grid and drill lines were generally at E- W direction Drilling sections are orientated perpendicular to the strike of the overall shear orientation and mineralised host rocks. Several shallow dipping vein structures are noted in the southern pit wall, but overall, the mineralised vein structures appear parallel to sub-parallel with the shear orientation from north to south. The drilling is angled at either -55° or -60°which is close to perpendicular to the dip of the shear trend and host units. No orientation-based sampling bias has been identified in the data at this point. |
| Sample security | The measures taken to ensure sample security. |
All samples are selected, cut, and bagged in tied numbered calico bags, grouped in larger tied plastic bags, and placed in large sample cages with a sample submission sheet to the assaylaboratoryin Kalgoorlie. |
| Audits or reviews | The results of any audits or reviews of sampling techniques and data. |
Data is validated by the contract database administrator whilst loading into the Javelin MS Access database. Pre Javelin data audits found to be satisfactory in regard to QAQC though in line with industrystandards of the time. |

| Geology | Deposit type, geological setting, and style of mineralisation. |
The Eureka gold deposit occurs on the eastern limb of the major south-east plunging Goongarrie-Mt. Pleasant Anticline. The eastern limb consists predominantly of north-north-west trending mafic and ultramafic lithologies, with minor thin mainly interflow sediments, bounded to the west by pre-to syntectonic granitoid forming the core of the regional anticline. To the east, the Bardoc-Broad Arrow Synform occurring between the major Goongarrie- Mt. Pleasant and Scotia-Kanowma Anticlines is subject to significant disruption by the broad Bardoc Tectonic Zone. This zone consists of multiple shear zones occurring within intercalated felsic, mafic and ultramafic lithologies in the vicinity of the synformal axis. The Bardoc Tectonic Zone is host to the Paddington and Bardoc gold deposits. Local Geology and Mineralisation The Eureka deposit is located within a sequence of mafic and ultramafic rocks forming part of the Kalgoorlie – Menzies greenstone belt. The layered sequence is approximatley 6 km wide with a northerly trend. The sequence is intruded by east-west trending Proterozoic mafic dykes and is bunded to the east and west by complex granitic plutons. In the vicinity of the Eureka Mine the sequence has a generally easterly dip of 65° to 70°, parallel by the regional foliation. Regional metamorphism of the sequence is lower greenschist facies. Two distinct shale units are present, the western or footwall unit being the Copper Mine Shale which marks the top of the sill and the hanging wall unit, an interflow unit amongst the basalt. Weathering profile is extensive with the deepest weathering along the main shear zones and contacts causing a weathering trough of highly oxidised rock that extends down the main shear to the bottom of the pit exposures. Both the north end and south end exposures of the pit show massive and blocky clay altered rock masses bounded by narrow, highly sheared zones, commonly containing limonitic quartz veining. The quartz vein hosted shears run parallel or sub-parallel to the main N-S shear trend, and less commonly cross cutting, shallow dipping quartz veins. |

| High grade gold mineralisation at Eureka is associated with veining within the altered lower mafics. The vein system typically consists of quartz, carbonate and sulphide and has a variable thickness of up to 20m. The mineralisation exploited in the open pit consists of a number of lens shaped shoots up to 10m wide within an intenselysheared zone some 30m wide. |

| 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: o easting and northing ofthe drill hole collar o elevation or RL (ReducedLevel – o elevation above sea levelin metres) of the drill hole collar o dip and azimuth of thehole o down hole length andinterception depth o 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. |
All relevant drill hole details were presented in ASX release in Appendix 1 |
| 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 |
All reported assays have been length weighted if appropriate. No top cuts have been applied. A nominal 0.5g/t Au lower cut off has been applied, with only intersections >0.5g/t considered significant. High grade Au intervals lying within broader zones of Au mineralisation are reported as included intervals. In calculating the zones of mineralisation, a maximum of 2 metres of internal dilution is allowed. Metal equivalent values have not been used. Only gold grade is reported. |

| 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. |
||
| 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 mineralised zones vary in strike between the Main and North prospects. Gold mineralisation is steeply dipping in the Main zone but more shallow drilling in the North prospect. Drill hole orientation reflects the change in strike of the rocks. Reported down hole intersections are believed to approximate true width. |
| 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. |
All relevant drill hole details were presented in ASX release. |
| 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. |
All significant results above the stated reporting criteria have previously been reported, not just the higher-grade intercepts. |
| 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 surveyresults; |
Groundwater, and geotechnical studies have not commenced as part of the assessment of the project. |

Section 3 Estimation and Reporting of Mineral Resources
(Criteria listed in section 1, and where relevant in section 2, also apply to this section.)
| Criteria | JORC Codeexplanation | Commentary |

| Database integrity | Measures taken to ensure that data has not been corrupted by, for example, transcription or keying errors, between its initial collection and its use for Mineral Resource estimation purposes. Data validation procedures used. |
The drilling database for the Eureka deposit is maintained by a contract database administrator from Delta Lithium. The below data was given to Javelin as part of the total data review. The Eureka drilling data was supplied to Cube in two MS Access files formats for the purposes of the 2021 MRE: They include the below access database. EUREKA_HIST_DB_Extract_Z51_20210323.accdb = (old holes) EUREKA_WAR_DB_Extract_Z51_20210430.accdb = (TIN holes, 2020- 21) Cube compiled the data for importing into a standard resource database in MS Access for use in the May 2021 Mineral Resource estimate. This database has been relied upon as the source of data for the 2021 MRE work. Cube carried out a database validation review of the supplied drilling data, supplied digital terrain models (DTM) prior to undertaking the resource estimation update. There were no old survey plans in digital format and no survey 3DM wireframes of the historical UG workings from 1897-1940, or the recent UG trial mining in 1998. Validation checks completed prior to MRE work for the MRE included the following: |

| Site visits | Comment on any site visits undertaken by the Competent Person and the outcome of those visits. If no site visits have been undertaken indicate why this is the case. |
Brian Fitzpatrick (Principal Geologist at Cube conducted a site visit on 9 June 2021. Inspection and reconnaissance mapping of the open pit workings Locate and GPS survey pickup of the approximate location of 26 WRRC holes Inspect available core from the 18EKDD program at the site field office facilities Review sample despatch and sample security facilities and procedures at the site field office. Review hard copies of CRMs, lab forms and logging documentation Discussions with geology and field staff regarding drilling and sampling protocols, QAQC procedures, drilling methods and equipment used, surveying, logging. The site visit noted that no bulk density (BD) sampling has been conducted and recommends that BD sampling take place in the near future. No previous BD information was source from historical documentation. The CP concluded from the site visit that apart from lack of BD sampling, other processes were deemed appropriate for the type of deposit and are carried out in accordance with standard industry practice. |
| Geological interpretation |
Confidence in (or conversely, the uncertainty of) the geological interpretation of the mineral deposit. Nature of the data used and of any assumptions made. The effect, if any, of alternative interpretations on Mineral Resource estimation. The use of geology in guiding and controlling Mineral Resource estimation. The factors affecting continuity both of grade and geology. |
The confidence in the geological interpretation of the mineral deposit is good as a result of the close, optimally spaced RC drilling confirming the location and tenor of mineralisation previously intersected by historical RC and DD drilling. In addition, previous mining activities such as the historical UG workings and open pit mining in 1985-86 indicate the presence of economic gold mineralisation based on the historical production figures: • UG Mining - 1897 to 1940: 809 tonnes at 27g/t Au, produced 797oz Au (Ransted, 1985) • Open Pit Production – 1985 to 1986: 45,865 tonnes at 4.64g/t Au, for 6,842 oz Au (WCH, 1986). The historical underground Eureka Gold Mine consists of several parallel gold lodes in a Main zone mineralisation modelled for the 2021 MRE. The gold is associated with quartz veins inside a north south trending, steeply east dipping shear zone. Within the northern zone the gold lodes appear to be parallel to the more shallow, east dipping shear planes. Grades are highly inconsistent within two main mineralised envelopes and appear to be offset by a NE-SW trend fault structure.

The data is informed by good quality drilling on regular drill spacing – down to 10 m x 10 m for the central area, broadening out to a nominal 25mE x 25 mN to the north and south of the Main zone. Maximum extrapolation of wireframes from drilling was 20m along strike or 10m down-dip. Maximum extrapolation along strike and below the deepest drilling was generally half drill hole spacing. Domaining and Compositing: • Drill hole sample data was flagged using domain codes generated from 3D mineralisation domains. Sample data was composited over the full downhole interval. Intervals with no assays were initially assigned background grades for the compositing routine as these un-assayed intervals in the drill holes were assumed to be waste or ‘barren’ during logging and sampling. It was decided therefore that unsampled intervals in the old holes used for the 2021 MRE were to be ignored in the compositing routine. • Assessment of the raw assay interval lengths and raw gold assay values were completed in order to determine the most appropriate length for compositing of the samples. The most common sample length is 1.0 m and covers the range of the Au grades. Therefore, 1 m composes were used as the source data for the gold grade estimates. • All domain composites included coding by weathering for oxide/transition versus fresh material. Statistical analysis of grade distribution for the well- informed domains by weathering was conducted, mainly to assess if further sub-domaining was required (e.g., evidence of supergene enrichment). No consistent variability in the sub-domaining by weathering was noted across the zones. Treatment of Extreme Grades: Gold grade distributions within the estimation domains were assessed to determine if high grade cuts or distance limiting should be applied. Distance limiting thresholds and the effects of grade capping were reviewed and applied on a domain basis where it was deemed appropriate i.e. for extreme high-grade outliers, high grade clustering or a high coefficient of variation (CV). Variography: Variogram calculations were carried out on the 1m composites for three well informed domains (1001, 1002, 1004). Variography failed to produce satisfactory results for other domains due to lack of samples. Indicator estimation was considered but did not provide sufficient data in the higher bins to produce well-structured variograms. |

Grade Interpolation and Search Parameters :
The mineralised domain wireframes were used to code the block model and the volume between the wireframe models and the coded block model were checked in order to ensure that the sub-blocking size are appropriate for the interpreted domains. Estimation was carried out on capped and uncapped gold grade. Hard domain boundaries were used between the mineralised domains, meaning only composites within the domain are used to estimate inside that domain. The variogram orientations were used as the orientation of the search ellipse. The variogram and search parameters for well-informed were used to represent the poorly informed domains.
Gold was estimated in two passes – first pass using optimum search distances for each domain (mostly 40 m) as determined through the KNA process, second pass set at longer distances in order to populate all blocks (2nd = max 120 m).
A waste domain boundary encompassing the mineralisation domains and within the limits of the drilling and host units was modelled for each deposit and included in the grade estimation runs. This allowed for any isolated zones and any mineralised haloes proximal to the hard boundary mineralised blocks to be estimated for estimation of dilution within pit optimisation limits. Interpolation parameters were set to a minimum number of 6 composites and a maximum number of 16 composites for the estimate. A maximum of 6 samples per hole was used.

The block model definition parameters included a primary block size and subblocking deemed appropriate for the mineralisation and to provide adequate volume definition where there are narrow or complex zones modelled. These dimensions are suitable for block estimation and modelling the selectivity for an open pit operation.
No correlation analysis has been undertaken due to limited number of multielement samples in the database provided.
The mineralisation domain interpretation was used at all stages to control the estimation. Overall, the mineralisation was constrained by wireframes constructed using a nominal 0.5 g/t Au cut-off grade lower threshold within shear-hosted, quartz veins and vein selvedges within a predominantly mafic/interflow sediments host units.
Statistical analysis was carried out for all domains. This involved a combination of grade capping analysis tools (grade histograms, log probability plots and coefficient of variation (CV)), and spatial analysis. The high CV and the presence of extreme grade values observed on the histogram for some of the domains suggested that high grade cuts were required for subsequent geostatistical analysis. The remaining domains were left uncut.
Top cuts were applied on a domain basis by application of grade capping for a domain composite data or using a grade distance threshold option in the interpolation module in Surpac.
The influence of extreme grade values was reduced by applying a gradedistance threshold limit for the estimation domains containing high grade outliers. Outside a distance of 20 m diameter (overall average drill spacing distance), a top cut was applied to the estimation domains. Grade capping values and effects are summarised as follows: range of top cut values = 10 g/t to 40 g/t (total of 17 samples cut) Metal loss based on composite mean and ratio of samples = -16%.
-
Block model validation was conducted by the following means: • Visual inspection of block model estimation in relation to raw drill data on a section by section basis.
-
Volumetric comparison of the wireframe/solid volume to that of the block model volume for each domain.
-
A global statistical comparisons of input and block grades, and local composite grade (by Easting and RL) relationship plots (swath plots), to the block model estimated grade for each domain.
-
• Comparison of the cut grade drill hole composites with the block model grades for each lode domain in 3D.
-
• Comparison with check estimates (OK or ID[2] )
-
No significant validation issues were noted from the model validation process. During interpolation runs, adjustments were made to search parameters to improve local and semi-local representation of grades where possible.

Whether assumed or
Bulk density Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples.
The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and differences between rock and alteration zones within the deposit.
Discuss assumptions for bulk density estimates used in the evaluation process of the different materials.
No environmental factors have been considered as part of the May 2021 MRE. The deposit areas have previous been the subject of historical underground and open pit mining and extensive surface work.
There were no bulk density (BD) results available for review for the 2021 MRE. No BD data was found from reports found in WAMEX. For preliminary resource work conducted in 2011, a BD of 2.65 was applied for all material rock types, regardless of degree of weathering.
BD assignment for the 2021 MRE has therefore been estimated from industry experience of similar material types in moderately to deeply weathered greenstone hosted gold deposits in Western Australia.
For the 2021 MRE, Cube assigned BD values for laterite, oxide, transitional and fresh material for both ore and waste:
| Material | Ore | Waste |
|---|---|---|
| Type | ||
| gm/cm3 | gm/cm3 | |
| Laterite | 2.2 | 2.2 |
| Oxide | 2.2 | 2.2 |
| Transition | 2.4 | 2.4 |
| Fresh | 2.75 | 2.8 |
| Voids | 0 | 0 |
It is assumed that the bulk density will have little variation within the separate material types across the breadth of the project area. Therefore, a single value applied to each material type is considered acceptable.
Classification The basis for the classification of the Mineral Resources into varying confidence categories. Whether appropriate account has been taken of all relevant factors (ie relative confidence in tonnage/grade estimations, reliability of input data, confidence in continuity of geology and metal values, quality, quantity and distribution of the data). Whether the result appropriately reflects the Competent Person’s view
The Mineral Resource estimate is reported here in compliance with the 2012. The resource was classified as Indicated, and Inferred Mineral Resource based on data quality, sample spacing, and lode continuity. The Indicated Mineral Resource was defined within areas of close spaced diamond and RC drilling (mostly 2020-2021 drilling) of less than 20 m by 20 m and where the continuity and predictability of the lode positions was good.
The Inferred Mineral Resource was assigned to areas of the deposit where drill hole spacing was greater than 20 m by 20 m and where small, isolated pods of mineralisation occur outside the main mineralised trends.

The resource classification is based on the quality of information for the drill types (recent RC and DD), geological domaining, as well as the drill spacing and geostatistical measures to provide confidence in the tonnage and grade estimates

Where appropriate a statement of the relative accuracy and confidence level in the Mineral Resource estimate using an approach or procedure deemed appropriate by the Competent Person. For example, the application of statistical or geostatistical procedures to quantify the relative accuracy of the resource within stated confidence limits, or, if such an approach is not deemed appropriate, a qualitative discussion of the factors that could affect the relative accuracy and confidence of the estimate. The statement should specify whether it relates to global or local estimates, and, if local, state the relevant tonnages, which should be relevant to technical and economic evaluation. Documentation should include assumptions made and the procedures used. These statements of relative accuracy and confidence of the estimate should be compared with production data, where available. |
The Eureka 2021 MRE is made up predominantly of moderately thick to narrow, very continuous mineralised gold zones hosted within sheared alteration zones containing high grade quartz veining. The close density of drilling supports the classification of 56% of the Mineral Resource to be classified as Indicated (by contained metal). The deposit geometry and continuity has been adequately interpreted to reflect the applied level for Indicated and Inferred Mineral Resources. The data quality is good, and the drill holes have detailed logs produced by qualified geologists. A recognised laboratory has been used for all analyses. The current modelled MRE is a reasonable representation of the global contained metal but not a local estimation. Confidence in the 2021 MRE is such that it will provide adequate accuracy for global resource evaluation for selective open pit mining. • 1897 to 1940 includes 809 tonnes recovery of 797oz of gold at an average grade of 27 g/t Au (Ransted, 1985). • Previously recorded gold production for the Eureka open pit mine during the period 1985 to 1986 includes 45,865 tonnes at an average grade of 4.64 g/t Au. Gold recovered has not been recorded. (WCH, 1987). • UG mine refurbishment & trial mining from November 1998 to June 1999 – approx. 400t @ 6g/t Au from 80m Level (JMM, 2000). • The historical mining figures indicate the presence of high-grade quartz vein hosted mineralisation also logged and sampled by more recent drilling. • The May 2021 MRE has been depleted by open pit mining based on open pit survey DTM. The accuracy of the depleted resource is affected to a minor degree by the exclusion of historical voids, although as only 809 tonnes was recorded as being mined (Ransted, 1985), it is not deemed significant for the global estimate. |

APPENDIX 3 – SUMMARY OF JORC TABLE 1 AND LISTING RULE 5.8.1
The following is a summary of material information used to estimate the Eureka Mineral Resource, as required by Listing Rule 5.8.1 and JORC 2012 Reporting Guidelines.
1. MINING HISTORY
The Eureka gold deposit was first discovered in the 1890s, with historical underground mining worked until 1940. Historical information sourced from WAMEX noted that gold mineralisation is associated with shearing and quartz veining within easterly dipping oxidised fine grained mafic rocks. Recorded production from 1897 up to 1940 totalled 809 tonnes averaging 27.8 g/t Au (Ransted, 1985).
More recently, the Eureka tenement area has been explored and operated by numerous companies, with the major work completed outlines as follows:

2. MINERAL TENEMENT AND LAND TENURE STATUS
The Eureka project is situated on tenement numbers M24/189, M24/584, M24/585 and M24/586 and P24/5116. The suite of five tenements is located 50 Kilometres north-west of Kalgoorlie. The tenements are owned 100% by Warriedar Mining (WRM). WRM is the operator of the tenement package. All licences are in good standing with no known impediments.
3. EUREKA DEPOSIT GEOLOGY AND MINERALISATION
Regional Geology
The Eureka gold deposit occurs on the eastern limb of the major south-east plunging Goongarrie-Mt. Pleasant Anticline. The eastern limb consists predominantly of north-north-west trending mafic and ultramafic lithologies, with minor thin mainly interflow sediments, bounded to the west by pre-to syntectonic granitoid forming the core of the regional anticline.
To the east, the Bardoc-Broad Arrow Synform occurring between the major Goongarrie- Mt. Pleasant and ScotiaKanowma Anticlines is subject to significant disruption by the broad Bardoc Tectonic Zone.
This zone consists of multiple shear zones occurring within intercalated felsic, mafic and ultramafic lithologies in the vicinity of the synformal axis. The Bardoc Tectonic Zone is host to the Paddington and Bardoc gold deposits.

ASX Announcement 25 October 2024
Local Geology and Mineralisation
The Eureka deposit is located within a sequence of mafic and ultramafic rocks forming part of the Kalgoorlie – Menzies greenstone belt. The layered sequence is approximatley 6 km wide with a northerly trend (Figure 1). The sequence is intruded by east-west trending Proterozoic mafic dykes and is bunded to the east and west by complex granitic plutons.

In the vicinity of the Eureka Mine the sequence has a generally easterly dip of 65° to 70°, parallel by the regional foliation. Regional metamorphism of the sequence is lower greenschist facies.
Two distinct shale units are present, the western or footwall unit being the Copper Mine Shale which marks the top of the sill and the hanging wall unit, an interflow unit amongst the basalt (Figure 2).
Weathering profile is extensive with the deepest weathering along the main shear zones and contacts causing a weathering trough of highly oxidised rock that extends down the main shear to the bottom of the pit exposures. Both the north end and south end exposures of the pit show massive and blocky clay altered rock masses bounded by narrow, highly sheared zones, commonly containing limonitic quartz veining. The quartz vein hosted shears run parallel or sub-parallel to the main N-S shear trend, and less commonly cross cutting, shallow dipping quartz veins (Figure 2).
Page 48
ASX Announcement 25 October 2024
High grade gold mineralisation at Eureka is associated with veining within the altered lower mafics. The vein system typically consists of quartz, carbonate and sulphide and has a variable thickness of up to 20m. The mineralisation exploited in the open pit consists of a number of lens shaped shoots up to 10m wide within an intensely sheared zone some 30m wide.

4. DRILLING TECHNIQUES AND HOLE SPACING
Historically, the project has been drilled using rotary air blast (RAB), percussion (Perc), reverse circulation (RC) and diamond core drilling (DD) over numerous campaigns by several companies and currently by TIN.
Eureka Open Pit – Recent view of Open Pit workings, looking south (Cube, June 2021)
For the 2020-2021 all drilling was completing using RC rigs. The RC rig specs are as follows:
-
Schramm T450 RC rig - 5 ½ inch diameter face sampling hammer
-
LC36 KWL700 RC rig (for deep holes) – 5 inch face sampling hammer
-
X350 RC rig - 4 ½ inch diameter face sampling hammer; drilling since May 2021)
The majority of holes are on a grid either infilling within or surrounding historical pit and underground (UG) workings or extending along strike into geochemical or geophysical (areo- mag) anomalies. The recent programs drilled in 2020 and 2021 have all been RC drilling. The majority of drill holes have a dip of -55 or -60° and azimuths mostly drilled to 270° MGA grid.
Page 49
ASX Announcement 25 October 2024
Historical exploration and drilling at Eureka targeted discrete areas based on surface geochemical and geophysical anomalies, historical workings that identified the location of host mineralisation. Consequently, current drilling is not grid based, but across the historical open pit and UG workings the drill spacing is nominally 10m N x 10m E. Extensions to the north and south have been nominally drilled at 20m N x 20m/10m spaced drilling. A plan view showing the drill spacing of holes used for the 2021 MRE within the Eureka project area are highlighted in Figure 3.

5. SAMPLING METHODS
Historical drilling reviewed from WAMEX files and carried out from 1982, included Vacuum, Augur, open hole percussion/ RAB, RC and diamond core drilling (mostly NQ, also PQ and HQ). Sampling methods included chip samples collected and split in even 1 metre or 4 metre composite intervals for dry samples. Wet samples were speared or on occasion scoop- sampled. Diamond core was half core sampled at selected intervals where the geologist recorded evidence of the presence of mineralisation.
For the recent drilling by TNT Mines Ltd (TIN), reverse circulation (RC) drill samples are collected from rig mounted cyclone cone splitter at 1m intervals. Duplicate samples are collected from reject bags every 10m (by spear sampling). Calico

ASX Announcement 25 October 2024
samples are weighed to ensure minimum size of 2.5kg are collected. Rarely where wet samples were encountered, the samples were speared or on occasion scoop-sampled. RC drill chips from each metre were examined visually and logged by the geologist. Duplicate samples were collected at 1 m intervals by scoop sampling reject bags.
Certified reference materials (CRM), analytical blanks, and field duplicates were used as part of the QAQC procedures used for the 2020-2021 RC drilling programs at Eureka and summarised as follows:
-
Insertion of CRMs after every 10 samples which represents approximately 5% of total samples. No blanks were inserted for the 2020-2021 RC drilling programs.
-
Insertion of field duplicates at a rate of one duplicate submitted for every 10 samples. Duplicates samples represent approximately 5% of total samples.
-
Based on the independent statistical analysis of the QAQC results, there is no evidence to suggest the samples are not representative. Analysis of the results to date show an acceptable level of precision and accuracy.
6. SAMPLE SECURITY AND LABORATORY ANALYSIS
Chain of custody is managed by TIN staff at the site office and core storage facility at Eureka. Between 300-400 samples are delivered in a batch directly by TIN personnel to the assay laboratory in Kalgoorlie by light vehicle and trailer with enclosed cage. Samples are securely packed in wire-tied, large hessian bags.
Two laboratories have been used for the 2020-2021 RC drilling, sample preparation and analysis: -
-
ALS, Kalgoorlie, certified ISO 9001
-
SGS, Kalgoorlie, certified ISO 9001
At the commercial laboratory, RC samples are dried at minimum 60° C. If the sample weight is greater than 3 kg, the sample is riffle split. It is then pulverised to a grind size where 85% of the sample passes 75 micron. All samples have been analysed using a 30g fire assay technique with an AAS finish.
All assay results are forwarded electronically to TIN for review by the CEO prior to validation and importing into the TIN database by contract database administrator.
7. ESTIMATION METHODOLOGY
Data is sourced from the recent and historical drill logging and RC chip logging/ DD core logging, and surface mapping interpretations from previous work. Interpreted projections for structures and local mineralisation trends were made between drill sections and extending along strike and down dip based on a drill spacing down to 10 m x 10 m. The logging and mining information has been used to inform the mineralisation domains used for the estimation.
Weathering surfaces were interpreted for oxide, transitional and primary weathering boundaries from available logging data. This data allowed the density values for the mineral resource estimate to be sub-divided by weathering domains.
Mineralisation continuity in the Main zone mineralisation consisting of 2 main zones in close proximity, following the trend of the main shear. Along the hanging wall and in the North zone, mineralisation is more inconsistent, although many old holes have selective sampling. Several significant gold intersections footwall to the FW graphitic shale were modelled into Au domain, and may indicate anomalous Au mineralisation along the footwall sequence.
Estimation domains were based on grouping of the gold mineralisation domains into five zones as defined by domain boundary threshold, nominally at 0.5g/t Au:
-
Domain 1001 to 1008 – Main Zone Au mineralisation
-
Domain 2001 to 2004 – North Zone Au mineralisation
-
Domain 3001 – Laterite Au mineralisation
-
Domain 100 – Min/Waste halo domain covering background mineralisation across the Main and North zones.

ASX Announcement 25 October 2024
Drill hole sample data was flagged using domain codes generated from three-dimensional mineralisation domains. Sample data was composited to one-metre downhole lengths using a best fit-method. No residuals were generated. Statistical analysis was carried out on data from all estimated domains, with hard boundary techniques employed within each estimation domain.
Gold grade distributions within the estimation domains were assessed to determine if high grade cuts or distance limiting should be applied. Distance limiting thresholds and the effects of grade capping were reviewed and applied on a domain basis where it was deemed appropriate i.e., for extreme high-grade outliers, high grade clustering or a high coefficient of variation (CV).
The mineralised domain wireframes were used to code the block model and the volume between the wireframe models and the coded block model were checked in order to ensure that the sub-blocking size are appropriate for the interpreted domains. Estimation was carried out on capped and uncapped gold grade. Hard domain boundaries were used between the mineralised domains, meaning only composites within the domain are used to estimate inside that domain. The variogram orientations were used as the orientation of the search ellipse. The variogram and search parameters for well-informed were used to represent the poorly informed domains.
Gold was estimated in two passes – first pass using optimum search distances for each domain (mostly 40 m) as determined through the KNA process, second pass set at longer distances in order to populate all blocks (2nd = max 120 m). A waste domain boundary encompassing the mineralisation domains and within the limits of the drilling and host units was modelled for each deposit and included in the grade estimation runs. This allowed for any isolated zones and any mineralised haloes proximal to the hard boundary mineralised blocks to be estimated for estimation of dilution within pit optimisation limits. Interpolation parameters were set to a minimum number of 6 composites and a maximum number of 16 composites for the estimate. A maximum of 6 samples per hole was used.
The parent block dimensions used in the block model were:
- 5 m N by 2.5 m E by 2.5 m RL, with sub-cells of 2.5 m by 1.25 m by 1.25 m.
The parent block size was selected on the basis one half/one quarter of the minimum drill spacing of 10/20 m E by 10 m N in Indicated areas and one quarter of the maximum drill spacing of 40 m E by 20 m N in Inferred areas. For the block model definition parameters, the primary block size and sub-blocking deemed appropriate for the mineralisation and to provide adequate volume definition where there are narrow zones or terminations, or disrupted zones due to contacts or surface boundaries.
The block model definition parameters included a primary block size and sub-blocking deemed appropriate for the mineralisation and to provide adequate volume definition where there are narrow or complex zones modelled. These dimensions are suitable for block estimation and modelling the selectivity for an open pit operation. A view of the block model constrained within the estimation domains is illustrated in Figure 4.

8. RESOURCE CLASSIFICATION
A range of criteria was considered by Cube when addressing the suitability of the classification boundaries. These criteria include:
-
Geological continuity and volume;
-
Drill spacing and drill data quality;
-
Modelling technique; and
-
Estimation properties, including search strategy, number of informing composites, average distance of composites from blocks and kriging quality parameters.
Blocks have been classified in both the Indicated (56% of total metal) and Inferred (44%) categories, primarily based on drill data spacing and well-defined Au mineralisation continuity, in combination with other model estimate quality parameters.
For Eureka, the following criteria was adopted for identifying the resource classification boundaries:
- The Indicated Mineral Resource was defined within areas of close spaced diamond and RC drilling (mostly 2020-2021 drilling) of less than 20 m by 20 m, and where the continuity and predictability of the lode positions was good.
Page 54
ASX Announcement 25 October 2024
- The Inferred Mineral Resource was assigned to areas of the deposit where drill hole spacing was greater than 20 m by 20 m and where small, isolated pods of mineralisation occur outside the main mineralised trends
9. REPORTING
In situ Resources
A summary of the in-situ Eureka Mineral Resources, as of 30 June 2021 is presented in Table 2. All resources have been depleted by previous open pit mining activity and are reported at a range of cut-off grades (COG). As the resources occur at or near surface, the models were constructed with a view towards selective open pit mining. Therefore, the selected Au lower cut-off ranges were deemed appropriate
