Announcement PDF 6 Altona Street, West Perth Western Australia, 6005 E: info@codaminerals.com ABN 49 625 763 957 Hydrogeological Drilling Concludes, Exploration Drilling to Commence at Elizabeth Creek Six-bore hydrogeological programme completed, drill rig to shift to the Oakden prospect and transition to exploration. Highlights • Hydrogeological drilling completed. Coda has completed its six-hole hydrogeological drill programme and established three production bores and three monitoring bores for ongoing groundwater monitoring in support of its environmental approvals and mining engineering studies. • Oakden exploration to commence. With the hydrogeological programme finalised, the rig will move to Oakden for exploration drilling targeting shallow mineralisation of the same style as MG14 and Windabout. • Critical PFS and approvals data to be collected in coming weeks. Pump testing of the newly constructed bores will commence following completion of onsite earthworks; results will inform environmental approvals, mine dewatering requirements and anticipated water supply for future mining operations. Coda Minerals Limited (ASX: COD, "Coda", or "the Company") advises that its hydrogeological drilling programme has now been completed at its 100%-owned Elizabeth Creek Copper-Silver Project in South Australia. The programme included a total of 6 drillholes: 1 production bore and 1 monitoring bore at the Windabout open-pit prospect, and a further 2 production bores and 2 monitoring bores at the Emmie Bluff underground prospect. Total drilling comprised 1,378m (764m of monitoring bores and 614m of production bores). Full details are provided as Table 1, and a map of the bores is presented as Figure 1. Table 1 Hydrogeological borehole collar data for the recently completed programme. Coordinates are reported as MGA94 Zone 53.

ASX RELEASE 2026 Code: COD 28 October 2026 ASX:COD 6 Altona Street, West Perth Western Australia, 6005 E: info@codaminerals.com ABN 49 625 763 957 Commenting on the drill programme, Coda Minerals CEO Chris Stevens said: “Understanding groundwater conditions is essential to mine design and environmental approvals at Elizabeth Creek. With all six bores now completed, the next phase of pump testing will provide the data needed to plan mine dewatering, assess water supply and support the PFS and approvals process. “The rig will now move directly to Oakden for a focused, low-cost test of the shallow copper mineralisation reported in historical drilling. Our first objective is to verify that result and establish whether mineralisation extends beyond the original intersection. Positive results would provide a basis for further drilling to assess whether Oakden could contribute early, near- surface feed to Elizabeth Creek.” Results and Next Steps All six bores were completed and constructed as designed. Anticipated flow rates will be determined by pump testing, during which water is pumped from each of the three production bores for up to 48 hours at a time, with the groundwater response recorded via the monitoring bores. This pump testing programme will commence as soon as practicable following completion of onsite earthworks – specifically the construction of large “turkey’s nest” dams to control saline water run-off. This work is currently expected to begin later in 2026, following the Oakden exploration programme. The data collected during pump testing will feed the regional hydrogeological model which the company is constructing for the Project’s Mining Lease Application and environmental approvals pathway, helping Coda anticipate and manage potential impacts on surrounding water users and any groundwater-dependent ecosystems (noting that surveys to date have not identified any such ecosystems at Elizabeth Creek) well ahead of project construction. This same model will also support the ongoing Pre-Feasibility Study (PFS), informing dewatering and depressurisation planning for the open-pit and underground workings, informing underground geotechnical parameters and helping develop the overall site water balance. The results of the site water balance calculation will partially determine the next steps in the field. If water availability is identified as a potential risk, a further programme to define available water resources and plan a production bore field may be required or, if water risk is assessed to be low, that programme may be deferred to the Definitive Feasibility Study (DFS). All bores were geologically logged during drilling. While none of these holes were specifically designed to test for mineralisation, MB26EB0001, located north-west of DD25EB0038 as noted in the Company's announcement of 23 July 2026, also served a secondary exploration purpose, however the hole did not intersect Tapley Hill Formation black shale. This hole was drilled well outside the Emmie Bluff Mineral Resource outline, and the result has no bearing on that estimate. It has been incorporated into the Company's geological model and will help refine future exploration targeting to the south of Emmie Bluff. 6 Altona Street, West Perth Western Australia, 6005 E: info@codaminerals.com ABN 49 625 763 957 Figure 1 Location of the Windabout and Emmie Bluff hydrogeological drill holes at the Elizabeth Creek Project. Oakden Exploration With the hydrogeological programme complete, the rig will now move to the Oakden prospect, approximately 15km south- southwest of the MG14 Mineral Resource and historic Cattle Grid open pit. As outlined in the Company's announcement of 19 August 2026, the programme will follow up historical drillhole OK36, which intersected 3m @ 1.15% Cu from 39m within relatively shallow Tapley Hill Formation black shale2. The Company cautions that this is a historical result and detailed information regarding assay and QA/QC procedures is not available. A key purpose of the programme is to test the reliability and repeatability of this result. The initial phase will comprise approximately 5–6 shallow RC holes for around 300–400m, focused on the immediate vicinity of OK36. The holes are designed to confirm the historical intersection, test short-range continuity at distances of approximately 50–200m, and confirm the interpreted geometry of the Tapley Hill Formation. Subject to the results, Coda will consider a second phase of approximately 12–22 holes to test the broader interpreted corridor. 2 For more details, including JORC Table 1, please see “Oakden Shallow Copper Drilling Set to Commence”, released to the market on 19 August 2026 and available at https://codaminerals.com/announcements/7bbkN5-oakden-shallow-copper-drilling-set-to-commence 6 Altona Street, West Perth Western Australia, 6005 E: info@codaminerals.com ABN 49 625 763 957 - This announcement has been authorised for release by the Board of Coda Minerals Ltd.

Statement Regarding Metal Equivalent Calculations Metal Equivalent grades are quoted for one or more of the Emmie Bluff, Windabout and MG14 Mineral Resources, or for exploration results considered by the company to be related directly to one of these Mineral Resources, in this announcement. For the Emmie Bluff Mineral Resource: The Emmie Bluff Mineral Resource is reported as 40.2Mt @ 1.27% Cu, 569 ppm Co, 16.8 g/t Ag and 0.17% Zn (1.87% Copper Equivalent (CuEq)) reported at a cut-off grade of 1% CuEq. The calculation of this metal equivalent is based on the following assumptions. Metal Coefficient Forecast Price Price Unit Copper 0.8 $7,000 USD/Tonne Cobalt 0.85 $55,000 USD/Tonne Zinc 0.9 $2,100 USD/Tonne Silver 0.85 $18.50 USD/Oz Price assumptions used when calculating copper equivalent grades were based primarily on Consensus Economics forecasts of metals, except for Cobalt, which was sourced via communication with subject matter experts. Metallurgical assumptions used when calculating copper equivalent grades were based on a simple bulk float utilising rougher and minimal cleaner/scavenger circuits. This produced a reasonably consistent mean recovery across most metals of between approximately 83 and 94 percent. For simplicity, and to in part account for losses associated with less intensive cleaner floats and losses to the hydromet plant, these figures were rounded down to the nearest 5%. Application of these assumptions resulted in the following calculation of CuEq: 𝐶𝑢𝐸𝑞% = 𝐶𝑢% + 0.00068 × 𝐶𝑜 𝑝𝑝𝑚 + 0.337 × 𝑍𝑛 % + 90.3 × 𝐴𝑔 𝑝𝑝𝑚 10000 For the Windabout and MG14 Mineral Resource: The Windabout and MG14 Mineral Resource are reported at a cut-off grade of 0.5% CuEq as: • Windabout: 17.67Mt @ 0.77% Cu, 492 ppm Co and 8 g/t Ag (1.41% CuEq) • MG14: 1.83Mt @ 1.24% Cu, 334 ppm Co and 14 g/t Ag (1.67% CuEq) The calculation of this metal equivalent is based on the following assumptions. Metal Mining Recovery % Dilution % Recovery % Payability % Forecast Price Price Unit Copper 0.9 0.05 0.6 0.7 $6,600 USD/Tonne Cobalt 0.9 0.05 0.85 0.75 $55,000 USD/Tonne Price assumptions used when calculating copper equivalent grades were based on recent historical metal prices at the time of calculation (2018). Metallurgical assumptions are based on extensive metallurgical testwork undertaken on the two deposits to 2018 across various potential flowsheets involving both floatation and leaching. Ag analyses in the estimation and metallurgical testwork were considered insufficient at the time to include in the metal equivalent calculation. Application of these assumptions resulted in the following calculation of CuEq: 6 Altona Street, West Perth Western Australia, 6005 E: info@codaminerals.com ABN 49 625 763 957 𝐶𝑢𝐸𝑞% = 𝐶𝑢% + 0.0012 × 𝐶𝑜 𝑝𝑝𝑚 It is the opinion of the company that both sets of prices used in the calculations are reasonable to conservative long-term forecasts for real dollar metal prices during the years most relevant to the deposits (approx. 2026- 2030). It is the opinion of the company that all of the elements included in the metal equivalent calculations have a reasonable potential to be recovered and sold.

Criteria JORC Code explanation Commentary Sampling techniques • Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. • For MB26EB0001: Core was logged in the field by Coda Minerals’ field geologists. Given the stratabound nature of the deposit and the absence of the host stratigraphy, as well as the XRF results, no sampling for assay was undertaken. Sampling is typically restricted to areas of intersected Tapley Hill fm. and immediate surrounds. A small number of whole core samples were taken for geotechnical testwork. • Portable XRF readings were taken in the field using an Olympus Vanta M tool applied directly to the core at points of interest, depending on prior results or visual identification of potential grade by the field geologist. The sample was not prepared except by standard cleaning of core by driller’s offsiders. XRF readings were taken at ambient winter daytime temperature for Woomera in South Australia, between approximately 10 and 30 degrees Celsius. • The device was used in 3-beam mode, scanning for a total of 10, 10 and 10 seconds for the two 40 KV beams and the final 50KV beam respectively. The device is designed to minimise drift over time, but has not been calibrated in the last 12 months. The results have not been corrected or otherwise adjusted. • Minor QA/QC is performed during reading, including duplicates and a series of standards and blanks taken at the start of each recording cycle. • For all other Drillholes: No sampling was undertaken for these holes as they were not drilled for mineral exploration. 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). • Water bores were drilled with a combination of wide-diameter conventional hammer and PCD mud rotary, depending on the diameter (maximum 12 inch) and drillhole conditions. • MB26EB0001 was completed as HQ core from approximately 303.4m. • Core was not oriented as the hole was vertical. 6 Altona Street, West Perth Western Australia, 6005 E: info@codaminerals.com ABN 49 625 763 957 Criteria JORC Code explanation Commentary 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. • Recovery of diamond core has generally been excellent, with minimal core loss. • No relationship is believed to exist between sample recovery and grade. 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. • Detailed qualitative geological logging of all diamond core has been and is being carried out by appropriately trained and experienced field geologists. Quantitative logging by means of portable XRF has been undertaken on an as needed basis in areas of prospectivity. • Other drillholes were logged by trained hydrogeological technicians and hydrogeologists, with a focus on sedimentological characteristics and stratigraphy. • For the purposes of describing mineral (particularly sulphide) abundance, the following descriptors have been used: Trace: Logged occasionally by field geologists within the logged interval, but not sufficient to estimate a percentage. Typically, <0.5% mineral abundance. Minor: Logged regularly by field geologists but does not make up a significant amount of the rock volume. Typically <5% mineral abundance. Moderate: Easily noted and logged by field geologists, makes up a significant amount of rock volume but is not a dominant component. Estimated to fall within a range of 5-15% mineral abundance. Intense: Very easily noted by field geologists, makes up a significant percentage of the rock volume and is a dominant component (15 – 50% mineral abundance). Volumes beyond 50% would be better represented as massive or near-total replacement of host rock rather than expressed as an intensity of alteration or sulphidation. 6 Altona Street, West Perth Western Australia, 6005 E: info@codaminerals.com ABN 49 625 763 957 Criteria JORC Code explanation Commentary 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. • No new assay results are reported as part of this announcement. Quality of assay data and laboratory tests • The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. • For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. • Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. • No new assay results are reported as part of this announcement. 6 Altona Stree
