Announcement PDF MRG Metals Limited ABN: 83 148 938 532 / ASX Code: MRQ Phone: +61 3 5330 5800 / Fax: +61 3 5330 5890 12 Anderson Street West, Ballarat VIC 3350 / PO Box 237 Ballarat VIC 3353 www.mrgmetals.com.au / info@mrgmetals.com.au ASX ANNOUNCEMENT 15 September 2026 Step-Out Grid Auger Drilling Outlines a Growing 1.6 Sq Km Mineralised Footprint at Adriano REE Project Highlights A well mineralised (refer Figure 4) footprint measuring 1.6 sq km (refer Figure 3) has been established by grid auger drillholes at hole spacings of 20 to 200 metres and hole depth averaging 1.8 metres within Adriano 11002 REE licence. The mineralised footprint was developed initially by 20 metre step-out holes (Table 1) around previously reported exploration pits (refer ASX Announcement 8 July 2026). Drill hole spacing was then increased outbound from the pits to 200 metres (Table 2). Visually estimated grade in these step out holes is consistent with visually estimated auger grades observed in previous holes within the footprint, that later recorded high grade HMS in assays (refer Figure 4). Previously reported mineralogical Study of a bulk sample of associated alluvial material (refer ASX Announcement 8 July 2026), produced Valuable Heavy Mineral (VHM) content of: ▪ 1.9% Monazite; ▪ 2.3% Rutile; ▪ 1.90% Zircon; ▪ 1.8% Leucoxene; and ▪ 24.4% Ilmenite. ▪ 32.2% Total VHM of the HMC. Substantial exploration potential already exists by continuing to expand this mineralised footprint down the alluvial drainage system, representing a 13km strike length (refer Figure 1). This zone contains a number of existing targets with assay results that have been previously reported to the market. Further potential exists to develop large, mineralised footprints across the Adriano and Fotinho tenements. MRG Metals Limited (ASX: MRQ) (“MRG” or “the Company”) is pleased to announce the a progress update on a grid drilling program at one of the alluvial targets, target Area 2 (refer Figure 2), within the Adriano REE project (refer ASX Announcement 13 July 2026; Figures 1 and 2). An initial 20 X MRG Metals Limited ABN: 83 148 938 532 / ASX Code: MRQ Phone: +61 3 5330 5800 / Fax: +61 3 5330 5890 12 Anderson Street West, Ballarat VIC 3350 / PO Box 237 Ballarat VIC 3353 www.mrgmetals.com.au / info@mrgmetals.com.au 20m auger grid (Table 1; 48 holes), followed by a 200 X 200m auger grid drilling program (Table 2; 51 holes) (Figure 3), showed all the holes generated were mineralised to well mineralised with heavy minerals (Figure 4). An area of 1.6 sq km has been covered by the 20 and 200m auger grid, to an average depth of 2m for the 20m grid holes and 1.8m for the 200m grid holes, with all the holes mineralised to well mineralised. Approximately 25% of the holes did not reach subcrop due to the water table. Holes on the northern, western and southern side of the 200m grid (Figure 4) still show significant mineralisation, showing promise for the extension of mineralisation in these directions. Background Target generation auger drilling of 201 holes (refer ASX Announcements 9 October 2025, 16 October 2025, 23 October 2025, 27 October 2025 and 4 March 2026 for Adriano targets; 1 June 2026 and 1 July 2026 for Fotinho targets) along streams and rivers within the Adriano 11002 and Fotinho 11000 licences generated numerous targets where well mineralised, deep terrace gravels were intersected. Samples from selected holes were sent for laboratory analyses, laboratory results confirmed holes with high total heavy mineral (THM%) grades, linked to significant depths to the water table or subcrop, thus suppling targets with combined 13km strike length (Figure 1) for follow-up exploration. • In one of these targets, Adriano Target 2, high THM laboratory analytical results were received from the target generation auger drillholes (refer ASX Announcement 11 December 2025, Figure 2), with highlights: o AAG25015 with 6.41% THM over 3.00m depth. o AAG25017 with 5.71% THM over 3.50m depth. o AAG25021 with 6.20% THM over 3.00m depth. o AAG25024 with 6.94% THM over 3.00m depth. • A pitting program was conducted within Target Area 2 and showed mature, well compacted, highly mineralised terrace gravel deposits to 3.7m depth (refer ASX Announcement 8 July 2026). • A grid drilling program, with initial grid spacing of 20m X 20m around the pits, followed by a wider area of 200m X 200m grid drilling, has now been completed around the high grade holes and the 2 pits within the Adriano Target Area 2 (refer ASX Announcement 13 July 2026; Figures 1 & 2). • The grid drilling program aims to develop an understanding of the grade, dimensions and mineralogy of the mineralised alluvial terraces around the river, to ultimately generate a JORC Mineral Resource Estimate (MRE). • Grid drilling will now continue at the numerous additional targets generated within both the Adriano and Fotinho licences, with two main areas for further grid drilling idetified in Adriano and Fotinho, showing a combined strike length of 13km (Figure 1) (refer ASX Announcements 9 October 2025, 16 October 2025, 23 October 2025, 27 October 2025 and 4 March 2026 for Adriano targets; 1 June 2026 and 1 July 2026 for Fotinho targets). • Mineralogical studies will be conducted on a lithological basis from different lithologies identified in Pit 3, as well as from the grid drilling auger holes. The aim is to detemine if the bulk sample mineralogy, with samples from Adriano Area 2 included, is consistent.

spaced grid auger drilling programs undertaken represent the first drilling to define the strike, width and depth potential, as well as grid-based grade and lithological information, of the identified alluvial deposits / terraces around the active streams and rivers. The visual mineralisation discussed will be confirmed via laboratory analyses. There is no guarantee on what exploration will uncover in terms of the dimensions / mineralisation of the alluvial deposits. Positive results will result in additional infill / step-out drilling. MRG Metals Chairman, Andrew Van Der Zwan, said: "The step out work at Adriano has continued following our recent Capital Raise and recognises Adriano/Fontinho as a valuable critical mineral asset. Our low-cost exploration has enabled us to develop a sizeable footprint with further opportunity to grow to economic scale.

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 • Samples from the Johnson T-type, 75mm bucket hand-auger are collected at 0.5m interval and composited to 1m intervals. • Samples of c 2kg are then sent to the analytical laboratory for analyses. • At each 0.5m sample a photo is taken showing the sample bag with hole ID and depth, as well as a panned sample for the interval. • Close attention is paid to any collapse taking place in the hole due to associated contamination of samples, the hole is immediately stopped if collapse takes place. If the required depth has not been reached, a re-drill takes place.

Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. 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). • Follow-up hand-auger drilling of alluvial deposits (46 holes to date) adjacent to previously reported stream sedimentary sampling points were undertaken program on Adriano 11002. • The hand-auger is a Johnson T-type, 75mm bucket auger with 1m extension rods and a handle crossbar. • The hand-auger samples are from a bucket auger, thus face-sampling with minimal contamination. 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. • When the bucket auger is re-inserted into the drillhole after collecting the sample from the bucket, close attention is given that the depth the auger goes to is the same depth as per previous drilling. If not, collapse has happened and the hole is redrilled, or seen as completed to the collapsed depth. • Each 0.5m sample is weighed.

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 auger samples are geologically logged, both the fine and coarse fractions • The full sample for each intersection is collected, no sieving of oversize is taking place in the field. • Analyses at the analytical laboratory is quantitative as it will supply the exact information needed for MRE work. • Photographs were taken of each 0.5m sample interval, showing the sample bag with hole and depth ID, as well as a heavy mineral concentrate (HMC) pan for each interval. A visual estimation of the THM% is made for each 0.5m interval. 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, • The full 0.5m sample is collected in a plastic bag. • Samples are transported to the sampling handling facility • 0.5m samples are then combined within each drillhole into 1m intervals. • A c 2kg sample were riffle split for laboratory work, the rest of the sample is stored at the camp area. • No screening or sieving took place on site.

Whether sample sizes are appropriate to the grain size of the material being sampled. 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 (eg standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. • Samples from the reported 20m and 200m grid spaced auger drilling program have not been delivered for analytical work at a laboratory yet. • The samples will be sent to MAK Analytical in South Africa for analyses. • Samples are dried; then the % Silt (45µ) and oversize (>1mm) determined; Followed by %THM on the -1mm +45µ fraction by Tetrabromoethane (SG 2.95). • The field derived visual panned THM estimates will be compared to a range of laboratory derived THM images of pan concentrates. This allows the field geologists to corroborate the field panned visual estimated THM with known laboratory measured THM grades.

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. • Field photographs of every sample is done showing panned HMC for every sample. • The Chief Geologist checks the logged data vs the analytical results for each sample interval when analytical results are received. • The geologic field data is manually transcribed into a master Microsoft Excel spreadsheet which is appropriate for this stage in the exploration program. • The raw field data is checked in the Microsoft Excel format first to identify any obvious errors or outlier data. The data is then imported into a Microsoft Access database where it is subjected to various validation queries. • Test work has not yet been undertaken at a Secondary laboratory to check the veracity of the Primary laboratory data. This work is planned as part of the Company’s standard QA/QC procedure. • A process of laboratory data validation using mass balance is undertaken to identify entry errors or questionable data. • Field and laboratory duplicate data pairs (THM/oversize/slime) of each batch are plotted to identify potential quality control issues. 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. • The location data from all sampling in is via a handheld Garmin GPS. The handheld GPS has an accuracy of +/-5m in the horizontal, with this accuracy sufficient for the early phase target generation work taking place. Data spacing and distribution Data spacing for reporting of Exploration Results. • The hand-auger drilling was initiated on a wider spacing to determine if mineralisation is present in the alluvial deposits.

Whether sample compositing has been applied. analytical results have shown high %THM and reported positive results from mineralogical investigations have result in infill drilling to facilitate geological and grade interpretation and modelling. • A closely spaced 20m auger grid was followed by a wider 200m auger grid drilling programs. These drilling programs at 1 alluvial target, Target Area 2 in Adriano, are now the first exploration done to define mineralisation areas for resource work. 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 alluvial deposits are adjacent to a river system and are being drilled out to depth of drilling refusal. • Initial auger drilling only covers alluvial deposits along the rives to generate targets, the 20m and 200m grid drilling programs are now covering these mineralised targets around the river systems. Sample security The measures taken to ensure sample security. • All samples remain in the custody of Company representatives on the project areas, as well as during transport to the sample export facility. • A reputable commercial shipping company, DHL, is used to transport the samples directly to the analytical laboratory. Audits or reviews The results of any audits or reviews of sampling techniques and data. No review has taken place on data to date.
