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 (eg ‘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 (eg submarine nodules) may warrant disclosure of detailed information. • Reverse Circulation (RC) percussion techniques were employed. • RC samples were collected from a cone splitter mounted on the rig cyclone at predominantly one metre intervals. Samples submitted to the laboratory, were single metre samples, were nominally 3 kilograms in weight. • All samples submitted for analysis were split PA-R and a 500-gram subsample was split off for Photon assay (PAAU002) determination of gold. Drilling techniques • Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg 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). • Face sampling RC Hammer drilling methods were employed. • RC hole diameter either 133mm or 140mm. • Reflex EZ Gyro downhole survey instrument was used to determine the drill direction( Azimuth) and dip of drillhole 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. • Visual measure of RC chip sample recoveries was made and recorded where significantly less than expected volume. Monitoring of sample quantity and quality was maintained by geologists and technicians attending the rigs during drilling operations. • Sample recovery maximized through use of auxiliary and booster compressors to manage sample return and ground water inflow. • Sample system hygiene checked and maintained at rod changes.

Sample bias has not been detected. RC Drilling was discontinued when dry sampling was no longer achievable. • Due to the mineralisation being hosted in quartz veins and interpreted post- mineralisation fracturing of zones within the overall lode, most core loss instances were in heavily veined intervals where veins had been naturally shattered and it is expected that this has downgraded many of these affected intervals although this has not been quantified. 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 RC chip samples were geologically logged on an individual metre basis. Logging is qualitative and captures details of lithology, oxidation, texture, mineralisation, alteration, veining, sample quality and recovery. Representative samples of all individual RC samples were retained in chip trays. • The data captured from geological logging is of appropriate standard, focus and detail to support future Mineral Resource estimations, mining studies and metallurgical studies. 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. • RC samples were collected by cone splitter in one and three metre composites. Where required, samples were riffle split to achieve appropriate weight of sample for laboratory submission. Excessively wet samples were subsampled by grab or tube spear methods where complete drying was not practicable. . • Field duplicates are collected and submitted for analysis at regular intervals throughout the drilling campaigns. Approximately 5% of RC samples are duplicated and submitted for analysis. • Sample weights are such that the entire sample submitted to the laboratory is dried, crushed and Split for Photon Assay analysis. After this samples is retain in their containers and return for storage. • Subsampling methods employed throughout the laboratory process are appropriate for the material and deposit type. 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 • Drill samples were subject to Photon assay of a 500 gram split subsample giving total gold analysis of a representative sample of the in- situ material determined by Photon Assay (PA- R)analysis to a lower detection limit of 0.02 parts per million gold. • Approximately 12% of all samples submitted are for quality control purposes.

Approximately 5% of RC samples are duplicated. Commercially prepared Standard Reference Materials, including coarse blank material, are submitted with each batch of samples to monitor potential contamination in the preparation process and accuracy and consistency of the analysis process. Standards and blanks constitute approximately 8% of all samples analysed. • No geophysical methods were used for elemental determinations. 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 drilling data including significant intersections is verified and validated by other geologists or Competent Persons within the organisation. • Dedicated twinning of holes has previously been employed in a limited capacity to verify mineralisation intersected in historic drilling campaigns. The natural sub-surface ground conditions and the extensive recent surface disturbance precludes close spaced duplication of previously drilled holes. Current drilling is infilling the drill spacing for additional Resource evaluation and verifies historic RC and diamond drilling intersections with respect to location, nature and tenor of mineralisation. • Drilling data is manually and digitally captured according to written procedures and a library of standard logging codes appropriate to this project and purpose. Manually captured data is transferred to digital templates where it is validated and then loaded to an externally managed and maintained database, again with validation protocols. Original data and reports are stored at the Company’s Headquarters. • No adjustments to assay data have been made. Raw assay data is provided to the external database managers where it is loaded to the database, securely stored and quarantined. 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 planned drill holes and drilled hole collars are surveyed using Trimble R8 RTK DGPS. Drill hole trajectories are measured using Reflex EZ- Trac or Reflex EZ-Gyro down hole survey tools. Drill rigs are aligned using Reflex TN14 Gyro Compass. • Grid is WGS84 Zone 30N and Vertical Datum is referenced to mean sea level. • RTK DGPS positioning is calibrated against pre-established primary planimetric survey control with tie-in to the Geodetic Reference Network.

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. • Drill holes are designed at an irregular spacing in this campaign principally to infill drill coverage for Resource definition and estimation purposes. Earlier work has established the required parameters for Mineral Resource classification. • The drilling data will be used in a Mineral Resource estimation. • Sample compositing has not been applied as samples were taken a 1m intervals only 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. • The primary controls on the gold mineralisation are presently well understood. Drill holes in this campaign were designed to intersect the mineralisation as normal to the primary control orientation as possible to reduce or eliminate any possible sampling bias. Sample security • The measures taken to ensure sample security. • Chain of custody for samples is managed by Tribune personnel and contractors on site. Samples are stored on site until collection by Intertek Laboratory personnel for transport to the Tarkwa laboratory facility. Audits or reviews • The results of any audits or reviews of sampling techniques and data. • Data and data collection methods are continuously reviewed for accuracy and adherence to procedures by Tribune and Principal Contractor personnel.

Data aggregation methods • In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg 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. • Significant intersections are reported as length weighted averages of all samples within the composite interval. Criteria used to calculate significant intersections can vary and are presented with each table of results. • No top cut of grades has been applied to the results reported. • Significant intersections are reported in the context of any likely mining extraction scenario. In the case of the Adiembra deposit, and notwithstanding the outcomes of any future Mineral Resource update or Reserve estimation, the likely mining scenario would be by open pit only and the significant intersections are presented with appropriate grade cut-offs and internal dilution criteria to reflect that method of extraction. Relationship between mineralisation • These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the • Primary gold mineralisation occurs within steeply dipping quartz veins.

TRIBUNE RESOURCES LTD (ASX:TBR) | ASX ANNOUNCEMENT Quarterly Report for September 2025 Page 21 of 27 JORC Code, 2012 Edition – Table 1 Mungari – Ambition Section 1 Sampling Techniques and Data (Criteria in this section apply to all succeeding sections.) Mungari – Ambition Section 1 Sampling Techniques and Data Criteria 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 downhole gamma sondes, 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 representation 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 completed 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, or unusual commodities/mineralisation types (e.g. submarine nodules). • Two sample types were used to collect material for analysis: surface diamond drilling (DD) and surface reverse circulation drilling (RC). • RC samples were split using a rig-mounted cone splitter on 1 m intervals to obtain a sample for assay. • Diamond core was placed in core trays for logging and sampling. Half core samples were nominated by the geologist from the diamond core with a minimum sample width of 30 cm. • Sample procedures followed by historic operators are assumed to be in line with RC sampling was split using a rig mounted cone splitter to deliver a sample of approximately 3 kg. • Surface diamond drill holes were completed using HQ (63.5 mm) core. DD drill core was cut in half using an automated core saw, the mass of material collected will vary on the hole diameter and sampling interval. • All samples were delivered to a commercial laboratory where they were assayed via photon analyses. Samples were dried, crushed to 3 mm for photon, at this point, large samples may be split using a rotary splitter, pulverisation to 90% passing 75 µm for fire assays. ~500g is selected for photon analyses or a 40g charge was selected for fire assay. industry standards at the time. 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.). • RC sampling was completed using a 4.5” to 5.5” diameter face sampling hammer. Diamond holes from surface were predominantly HQ (63.5mm) holes. • All diamond core was orientated where possible using the reflex (act II or ezi-ori) tool. • In many cases, RC pre-collars were drilled, followed by diamond tails. Pre-collar depth was determined in the drill design phase depending on the target being drilled and production constraints. Drill sample recovery • Method of recording and assessing core and chip sample recoveries and results assessed. • RC drilling sample weights were recorded for selected sample intervals and monitored for fluctuations against the expected sample weight. If samples were below the expected weight, feedback was For personal use only

TRIBUNE RESOURCES LTD (ASX:TBR) | ASX ANNOUNCEMENT Quarterly Report for September 2025 Page 22 of 27 Mungari – Ambition Section 1 Sampling Techniques and Data Criteria Explanation Commentary • 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. given promptly to the RC driller to modify drilling practices to achieve the expected weights. • All diamond core was orientated and measured during processing and the recovery recorded into the drill -hole database. The core where possible was reconstructed into continuous runs on a cradle for orientation marking. Hole depths were checked against the driller’s core blocks. • Inconsistencies between the logging and the driller’s core depth measurement blocks are investigated. Core recovery has been acceptable. Surface drilling recoveries were generally excellent except oxide zones; however, these rarely fell below 90%. • Measures taken to maximise sample recovery include instructions to drillers to slow down drilling rates or reduce the coring run length in less competent ground. • Recovery of RC samples was continuously monitored. Duplicate sampling (e.g., field splits) was performed for every meter to assess reproducibility and identify heterogeneity or size-related segregation. • Recovery was excellent for diamond core, and no relationship between grade and recovery was observed. 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 drill chips and diamond core have been geologically logged to the level of detail required for the Mineral Resource estimation, mining studies and metallurgical studies. • All logging is both qualitative and quantitative in nature, recording features such as structural data, RQD, sample recovery, lithology, mineralogy, alteration, mineralisation types, vein density, oxidation state, weathering, colour, etc. All holes are photographed wet. • All RC and diamond holes were logged in entirety from collar to end of hole. 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. • Diamond core was half- core sampled, and the remaining half was retained in the EVN core farm. • All RC samples were split by a cone or a riffle splitter and collected into a sequenced calico bag. Any wet samples that could not be appropriately split were dried, then riffle split. • Sample preparation of RC and diamond samples was undertaken by external laboratories according to the sample preparation and assaying protocol established to maximise the representation of the mineralisation. Samples are sorted for processing. The material jaw crushed to a nominal 3mm particle size, and a 500g subsample was prepared for analysis. Grind checks are performed at the crushing stage (3mm) for Photon Assay samples. This 500g subsample was sealed into a plastic jar, weighed and labelled with a unique identifier and reference disk. Laboratory's performance was monitored as part of EVN’s QAQC procedure. Laboratory inspections were undertaken to monitor the laboratory's compliance with the EVN sampling and sample preparation protocol. • Quality control procedures adopted to maximise sample representation for all sub- sampling stages include the collection of field and laboratory duplicates and the insertion of certified reference material as assay standards (1 in 20) and the insertion of blank samples (1 in 20) or at the geologist’s discretion. Coarse blank material is routinely submitted for assay and is inserted into each mineralised zone where possible. The quality control performance was monitored as part of EVN’s QAQC procedure. • Umpire sampling is performed monthly, where 3% of the samples are sent to the umpire laboratory for processing.

TRIBUNE RESOURCES LTD (ASX:TBR) | ASX ANNOUNCEMENT Quarterly Report for September 2025 Page 23 of 27 Mungari – Ambition Section 1 Sampling Techniques and Data Criteria Explanation Commentary • Whether sample sizes are appropriate to the grain size of the material being sampled. • The sample sizes are considered appropriate for the laboratory test - work being conducted. In- situ grain sizes of the sampled materials have not been measured and most likely vary considerably. 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, calibration factors applied and their derivation, etc. • Nature of quality control procedures adopted (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. • The sampling preparation and assaying protocol used by EVN was developed to ensure the quality and suitability of the assaying and laboratory procedures relative to the mineralisation types. Fire assay and photon assay are tests designed to measure the total gold within a sample. Both methods have been confirmed as suitable technique for orogenic -type mineralisation. It has been extensively used throughout the Goldfields region. • No geophysical tools or other remote sensing instruments were utilised for reporting or interpretation of gold mineralisation, although aeromagnetic interpretation was used to build the structural model, which does constrain the mineralised envelope. • Quality control samples were routinely inserted into the sampling sequence and were also inserted either inside or around the expected zones of mineralisation. The intent of the procedure for reviewing the performance of certified standard reference material is to examine for any erroneous results (a result outside of the expected statistically derived tolerance limits) and to validate, if required, the acceptable levels of accuracy and precision for all stages of the sampling and analytical process. Typically, batches which fail quality control checks are re-analysed. 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 and data storage (physical and electronic) protocols. • Discuss any adjustment to assay data Independent internal or external verification of significant intercepts is not routinely completed. The quality control/quality assurance (QAQC) process ensures the intercepts are representative of the orogenic gold systems. Half core is retained at Mungari if further verification is required, and field duplicates used for verification of any assay value where required. The twinning of holes is not a common practice undertaken. Data which is inconsistent with the known geology undergoes further verification to ensure its quality. All sample and assay information are stored utilising the acQuire database software system. Data undergoes QAQC validation prior to being accepted and loaded into the database. Assay results are merged when received electronically from the laboratory. The geologist reviews the database, checking for the correct merging of results and that all data has been received and entered. Any adjustments to this data are recorded permanently in the database. Historical paper records (where available) are retained in the exploration and mining offices. No adjustments or calibrations have been made to the final assay data reported by the laboratory. Location of data points • Accuracy and quality of surveys used to locate drillholes (collar and downhole 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 drill holes have been surveyed for easting, northing and reduced level. Resource drill hole collar positions are surveyed by the site-based survey department or contract surveyors (utilising a differential GPS or conventional surveying techniques, with reference to a known base station) with a precision of less than 0.2m variability. Holes drilled prior to 2019 had downhole gyroscopic surveys completed at distance between 40 and 80 metres downhole, and again at end of hole. Holes drilled post 2019 had downhole gyroscopic surveys completed at an average of 10 m spacing downhole. For personal use only

TRIBUNE RESOURCES LTD (ASX:TBR) | ASX ANNOUNCEMENT Quarterly Report for September 2025 Page 24 of 27 Mungari – Ambition Section 1 Sampling Techniques and Data Criteria Explanation Commentary Recent data is collected and stored in MGA 20 Zone 51. Topographic control was generated from aerial surveys and detailed Lidar surveys to 0.2m accuracy. 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. Resource definition drilling spacing was typically 40m x 40m, to allow for classification as Indicated Resource for an Underground resource, or 20m x 20m for an Open Pit resource. Outside of the Indicated Resource, drill spacing is highly variable with Resource classifications applied appropriately. Data spacing and distribution is considered sufficient for establishing geological continuity and grade variability appropriate for classifying a Mineral Resource. Sample data is composited before grade estimation is 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. Drilling is planned to intersect the mineralisation in an orientation that does not introduce sample bias. The relationship between the drilling orientation and the orientation of key mineralised structures at Ambition is not considered to have introduced a sampling bias and is not considered to be material. Sample security • The measures taken to ensure sample security. Chain of custody protocols to ensure the security of samples are followed. Prior to submission, samples are retained on site and access to the samples is restricted. Collected samples are dropped off at the respective commercial laboratories in Kalgoorlie. The laboratories are contained within a secured/fenced compound. Access into the laboratory is restricted and movements of personnel and the samples are tracked under supervision of the laboratory staff. During some drill campaigns, some samples are collected directly from site by the commercial laboratory. While various laboratories have been used, the chain of custody and sample security protocols have remained similar. Audits or reviews • The results of any audits or reviews of sampling techniques and data. No audits have been undertaken for the drill holes at this stage. For personal use only

Mungari – Ambition Section 2 Reporting of Resource Development Results Criteria Explanation Commentary Mineral tenement and land tenure status • Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. • The security of the tenure held at the time of reporting, along with any known impediments to obtaining a licence to operate in the area. • All holes mentioned in this report are located on the M16/326. Mining lease held by the East Kundana Joint Venture (EKJV). The EKJV is majority owned and managed by Evolution Mining Limited (51%). The minority holding in the EKJV is held by Tribune Resourc es Ltd (36.75%) and Rand Mining Ltd (12.25%). There are no private royalty agreements applicable to M16/326. • No known impediments exist, and the tenements are in good standing. Exploration done by other parties • Acknowledgment and appraisal of exploration by other parties. • The Ambition target was originally defined in 2001 from magnetic ‘anomalies’ as “a continuation of the Arctic Structure mined in the Arctic Pit to the south”. A small drill program of four RC holes targeted the mineralised structure at Ambition in 2003. These holes failed to intersect the structure, presumably due to an offset of the aeromagnetic lineament. Other drilling in the area has absent or poor -quality geological logging. The 2003 drillholes assisted in successfully intersecting the target in this drill program, but beyond that, historical drilling provides little value in appraisal of the structure at Ambition. Geology • Deposit type, geological setting and style of mineralisation. • The Kundana camp is situated within the Norseman-Wiluna Greenstone Belt, in an area dominated by the Zuleika shear zone, which separates the Coolgardie Domain from the Ora Banda Domain. K2-style mineralisation consists of narrow vein deposits hosted by shear zones located along steeply dipping overturned hangingwall basalts. The K2 structure defines the contact between a black shale unit (Centenary shale) and intermediate volcaniclastics (Sparogville formation). In the northern part of the Ambition target, the hangingwall basalts are absent and the structure separates a gabbro and lithic gritstone from Spargoville Volcaniclastic rocks. Although it is unclear at this stage, the current interpretation is that the target structure in the northern part of the Am bition prospect is actually the confluence of the Strzelecki and K2 structures thus the basalt sequences are faulted out where the two structures converge. 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 of the drillhole collar o elevation or RL of the drillhole collar o dip and azimuth of the hole o downhole length and interception depth o hole length. • See Table 1 for a table of results. • All holes in this FY program are listed in the table. No drill holes are excluded from this report or from Table 1. Data aggregation methods • In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) • All reported assay results have been length weighted to provide an intersection width.
