Trek Metals Limited (ASX: TKM) (“Trek” or the “Company”) is pleased to advise that the first batch of assay results from the maiden Reverse Circulation (RC) drill program at the Kuro manganese discovery, within the 100%-owned Christmas Creek Project in Western Australia, have confirmed Kuro as a significant near-surface, high-grade manganese discovery. 2 Laboratory assays for the first 21 RC holes have confirmed the presence of an extensive high-grade, near-surface manganese system, with 10 holes returning grades above 20% Mn and 15 of the 21 returning intervals above a 5% Mn cut-off. The best result was returned from drill-hole 26XCRC020, which intersected 13m @ 34.9% Mn from 13m, including 10m at 42.3% Mn from 13m with a peak one-metre assay of 54.4% Mn. Hole 26XCRC007 returned another very high-grade interval of 4m @ 44.6% Mn from surface. Significant intercepts are reported in Table 1 and Figures 1-4 below. Table 1. Significant intercept table of laboratory assays for holes 26XCRC001 – 26XCRC021, using a 5% Mn lower cut-off for broad intercepts and a 20% Mn lower cut-off for high-grade sub-intervals (including) with a maximum internal dilution of 2m.

Figure 1. Plan view of Kuro, Gradient Array Induced Polarisation (GAIP) Chargeability anomalism shown as full-colour background with contour lines (white-red hot indicative of highly chargeable zones), manganese outcrop as grey polygons with black outlines, completed Reverse Circulation drill-holes with hole ID and total visual massive and semi-massive manganese intercepts labelled and new (this release) significant laboratory assay results in callouts and coloured dots. Readers are reminded that Visual estimates of mineral abundance should never be considered a proxy or substitute for laboratory analyses where concentrations or grades are the factor of principal economic interest. Visual estimates also potentially provide no information regarding impurities or deleterious physical properties relevant to valuations. The visually observed manganese mineralisation is not representative of the entire Kuro Prospect, with drilling currently on- going to further assess the distribution of manganese. Representative drill samples are being routinely collected from the drill rig and will be analysed at ALS laboratories and reported in due course (laboratory assay results are expected progressively, with the first batch reported now, the second batch in 2-4 weeks and the final Phase 1 batch in 3-5 weeks). Trek Metals CEO, Derek Marshall, said: “Receiving confirmation of high-grade manganese mineralisation below surface in these first laboratory assays represents a major breakthrough in our ongoing exploration program at Christmas Creek. Until now we have been working on outcrop rock chip assays and visual estimates in drilling. While the manganese mineralisation is typically quite visual, having laboratory verification that the high-grade mineralisation we see at surface does indeed continue below surface is a major milestone which gives our team the confidence to continue with the next phase of work. 4 “A preliminary review of the geochemistry - noting that these are early drill assays and not metallurgy - also indicates the potential for a product with low-iron and low-phosphorus in the manganese mineralised zones, with both iron and phosphorus being the principal penalty elements in manganese ores. This is very encouraging for the exploration potential for what we consider to be a potentially large system. “The thing that I find most encouraging about the Kuro manganese discovery is the regional context. Kuro is just one prospect area – one that we initially targeted as there was a small window of rocks sticking out of the ground in a region where most of the rocks are under shallow sand cover. We have a large, interpreted basin to explore and we are doing just that, with the Moombarriga IP crew continuing their surveys to identify future drill targets to determine where the RC rig goes next. “In the meantime, the rig is continuing to test regional targets as we commence earthmoving at the Coogan copper-gold target and Kuro prior to additional drilling. Two geophysical surveys are also due to commence shortly, with SAM over the Martin high-grade gold prospect and a regional airborne magnetic – radiometric survey. We look forward to updating the market with a steady flow of exploration results and activity as the season progresses.” Figure 2.

Down-hole continuity within the mineralised zones is good, with the five thickest intercepts comprising between 8 and 15 contiguous metres above cut-off. Iron and phosphorus are the principal penalty elements in manganese ore. Samples grading 20% Mn or better average 2.7% Fe and 0.04% P for an Mn:Fe ratio of approximately 13:1, with manganese and iron geochemically decoupled and the ratio improving with grade to 47:1 in the 10m @ 42.3% Mn interval in 26XCRC020, which returned 0.90% Fe. Phosphorus is low across most intercepts but is elevated in 26XCRC006 and 26XCRC007. Silica is the principal diluent and falls as manganese grade rises, from 47.5% SiO₂ across the reported intercepts to 24.4% in the highest-grade interval. Lead is variably distributed, ranging from 49ppm to 0.60% over the reported intercepts, and is lowest in the highest-grade material. Length-weighted averages for each intercept of 2m or greater are set out in Table 4. No metallurgical or product characterisation testwork has been undertaken. 6 Figure 4.

Preliminary Merged Residual Gravity imagery showing an interpreted ~16km long prospective Neoproterozoic basin hosting the Kuro manganese discovery outlined in white, highlighting the interpreted basin boundary and target stratigraphy within, the existing Kuro IP and drill area in the east and the recently completed gradient array IP extension survey areas. Notably, all the IP targets are under shallow sand cover with no surface manganese expression. Having a drill targeting technique that effectively pinpoints significant manganese undercover is therefore considered to be a pivotal moment for the Company in advancing the Kuro manganese discovery. The Moombarriga IP crew, which re-mobilised to site on 3 July 2026, has since completed additional Gradient Array Induced Polarisation (GAIP) surveying surrounding the Kuro Manganese Discovery and is now continuing this surveying to the north-east of the discovery area in an area that is interpreted to represent an extension of the basin hosting the manganese mineralisation at Kuro. 8 Authorised by the Board of Directors ENDS For further information contact: INVESTORS: MEDIA: Derek Marshall Nicholas Read dmarshall@trekmetals.com.au info@trekmetals.com.au 0419 929 046 JOIN TKM’S INTERACTIVE INVESTOR HUB https://trekmetals.com.au/auth/signup Interact with Trek Metal’s announcements and updates by asking questions and comments which our team can respond to where possible https://trekmetals.com.au/link/rDvGQy COMPETENT PERSONS STATEMENT The information in this report relating to Exploration Results is based on information compiled by the Company’s Chief Executive Officer, Mr Derek Marshall, a Competent Person, and Member of the Australian Institute of Geoscientists (AIG).

Length-weighted average composition of the significant intercepts reported in Table 1. Broad intercepts are calculated using a 5% Mn lower cut-off and high-grade “including” sub-intervals using a 20% Mn lower cut-off, each with a maximum internal dilution of 2m. Sub-intervals are contained within the broad intercept immediately above and are not additional to it; the weighted average row relates to the broad intercepts only. Broad intercepts of less than 2m downhole width are excluded from this table. Fe and P are reported as the element, converted from Fe₂O₃ and P₂O₅ respectively. Mn:Fe is the ratio of elemental manganese to elemental iron. LOI is loss on ignition. Sulphur is below 0.02% S across all reported intercepts and is not tabulated; combined K₂O + Na₂O averages 1.4% and CaO + MgO averages 0.4%. All results are reported on an as-received basis. Iron and phosphorus are the principal penalty elements in manganese ore; lead, arsenic, silica, alumina and barium are reported as constituents relevant to any future assessment of the mineralisation. No metallurgical or product characterisation testwork has been undertaken and no inference as to product specification should be drawn from these results.

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. • Drilling was undertaken using RC with a face sampling bit. RC cuttings were collected at 1m intervals via a cyclone and cone splitter, producing ~2.5kg (mean 2.42kg and median 2.31kg) samples, with bulk residues retained on site and composite sampled as 4m intervals. • All 21 holes were sampled over their full length with 638 one-metre samples plus 230 four-metre composites, with no composite exceeding 1% Mn. • Samples are freighted for analysis at ALS Perth using: o ME-XRF26s which consists of a Lithium Borate Fusion and X-Ray Fluorescence Spectroscopy analysis. This method is suitable for the determination of major and minor elements in ore samples which require a high dilution digest such as Chromite and high Manganese ores. o Fire assay with AAS finish (Au-AA25, 30g), and o Four-acid digest with ICP-MS (ME-MS61, 48 elements). These are considered industry-standard and appropriate methods. • Field duplicates, certified reference materials and blanks were inserted at a nominal rate of one of each per 50 samples, with laboratory internal checks also applied. All QA/QC results have been reviewed and are within acceptable limits — refer to the Quality of Assay Data and Laboratory Tests section below. Chain of custody was maintained from site to laboratory. • All holes completed have been included in figures within the body of the announcement and all collars relating to holes with new assays in this announcement are listed in tabular formats in Table 3 & significant intercepts in Table 1. • Visual estimates of manganese mineralisation have been estimated by trained and experienced mineral exploration geologists on the rig and reviewed by the Competent Person utilising chip tray photos. Visual estimates included have all been previously released and readers are referred to announcements listed in Table 2. The reader is reminded that Visual estimates of mineral abundance should never be considered a proxy or substitute for laboratory analyses where concentrations or grades are the factor of principal economic interest. Visual estimates also potentially provide no information regarding impurities or deleterious physical properties relevant to valuations. The visually observed manganese mineralisation is not representative of the entire Kuro Prospect, with drilling currently on-going to further assess the distribution of manganese. Representative drill samples are being routinely collected from the drill rig and will be analysed at ALS laboratories and reported in due course (results from the remaining two batches from Phase 1 are expected in 3-5 weeks). 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). • Drill testing was undertaken by Reverse Circulation (RC) with face sampling drill bit, drill cuttings are returned to surface via inner tubes in the drill string. • RC drill cuttings were collected at 1m intervals down the length of each hole. Sampling was completed from a gated cyclone over a static cone splitter into a calico bag with an average sample weight of 2.42kg per 1m sample. The remainder of the drill cuttings were collected in green bags and laid out in rows on a sample pad beside the drill rig. • Individual 4m samples were then composited from the green bags as described in a subsequent section. The sampling protocol is common 13 Criteria JORC Code explanation Commentary practice for RC drilling and considered appropriate for the stage of exploration. 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. • Reverse Circulation drilling recoveries have been good with consistency between green bag (and calico split) sizes. • Duplicate samples were collected from the rig every 50m, with duplicate pair weights monitored to check the performance of the cyclone and cone splitter. • Sample recovery was consistent across the program with the same drill rig and mostly the same driller operating the drill rig and maintaining constant drilling conditions with the equipment, including monitoring bit wear, air return, and cyclone performance. • A cone splitter was used on the drill rig which theoretically gives an even and impartial split of the sample when operated correctly. Adjustable control gates allow the sample size to be calibrated to suit the ground conditions and target sample size. These measures are best practice in producing representative samples. • There is no observed relationship between sample recovery and observed mineralisation.
