scalable boland discovery is a strategically advantageous ionic rare earth discovery where high grades of valuable heavy and magnet rare earths occur concentrated in a permeable horizon confined by impermeable clays. bench scale isr testing has confirmed that mineralisation is amenable to isr mining. isr has been used successfully for decades within geologically similar systems to recover uranium within south australia. results of this metallurgical test work support that, with minor optimisation, isr techniques should enable non-invasive and low-cost production of critical rees from cobra's boland discovery.   the manna hill project   cobra has entered a binding option deed to acquire the manna hill project, a forgotten porphyry province within the copper capital of australia. the project has the potential to deliver the next tier 1 discovery. historical intersections include 48m @ 2.2% cu & 0.76 g/t au and 132m at 0.5% cu, underpin the potential to deliver the next multi-million tonne copper resource.   further information relating to cobra's boland project is presented in the appendices.   enquiries:   cobra resources plc rupert verco (australia) dan maling

in 2023, cobra discovered a rare earth deposit with the potential to re-define the cost of rare earth production. the highly scalable boland ionic rare earth discovery at cobra's wudinna project in south australia's gawler craton is australia's only rare earth project amenable for in situ recovery (isr) mining - a low cost, low disturbance method enabling bottom quartile recovery costs without any need for excavation or ground disturbance. cobra is focused on de-risking the investment value of the discovery by proving isr as the preferred mining method and testing the scale of the mineralisation footprint through drilling.   cobra's wudinna tenements also contain extensive orogenic gold mineralisation, including a 279,000 oz gold jorc mineral resource estimate, characterised by low levels of over-burden, amenable to open pit mining.   regional map showing cobra's projects - the boland rare earth project & the manna hill copper project       follow us on social media:

information - the boland project and isr   ·    the boland project was discovered by cobra in 2023. mineralisation is ionically bound to clays and organics within palaeochannel sands within the narlaby palaeochannel   ·    mineralisation occurs within a permeable sand within an aquifer that is saltier than sea water and is confined by impermeable clays   ·    isr is executed through engineered drillhole arrays that allow the injection of mildly acidic ammonium or magnesium sulphate lixiviants, using the confining nature of the geology to direct and lower the acidity of the orebody. this low-cost process enables mines to operate profitably at lower grades and lower rates of recovery   ·    once rees are mobile in solution in groundwater, it is also possible, from an engineering standpoint, to recover the solution to surface via extraction drillholes, without any need for excavation or ground disturbance   ·    the capital costs of isr mining are low as they involve no material movements and do not require traditional infrastructure to process ore - i.e. metals are recovered in solution   ·    ionic mineralisation is highly desirable owing to its high weighting of valuable hreos and the cost-effective method in which rees can be desorbed   ·    ionic ree mineralisation in china is mined in an in-situ manner that relies on gravity to permeate mineralisation. the style of isr process is unconfined and cannot be controlled, increasing the risk for environmental degradation. this low-cost process has enabled china to dominate mine supply of hreos, supplying over 90% globally   ·    confined aquifer isr is successfully executed globally within the uranium industry, accounting for more than 60% of the world's uranium production. this style of isr has temporary ground disturbance, and the ground waters are regenerated over time   ·    cobra is aiming to demonstrate the economic and environmental benefits of recovering ionic hreos through the more environmentally aquifer controlled isr - a world first for rare earths   figure a1: comparison between the chinese and the proposed boland process for isr mining of rees   appendix 2: jorc

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. ·      drill results are historic, reported from previous explorers across multiple company databases. ·      gs series holes have uncertain sampling methods but 2024 hgrc series holes across reflected the grade tenor and distribution ·      blue rose drill results were undertaken over multiple generations with validation required. sample lengths were between 1m and 4m. sample types are listed as composites and splits in historically reported data for the reported results. ·      netrp series holes were completed in the late 1960s as percussion holes. results are considered reflective of typical grades and scale but are historic in nature. ·      netdd holes were diamond holes that were half core samples to 1m length. ·      select review of sampling data provided indicates the retained data is of good quality. 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). rab, ac, rc, percussion and diamond drilling methods have all been used with ac and rc being the dominant drill methods on a per m basis. further assessment of the drilling methods will be undertaken during data validation and migration. select review of drilling data provides indicates the retained data is of good quality. 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

further use.   appendix 3: section 2 reporting of exploration results   criteria jorc code 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. ·      el's 6009, 6046 and 6646 are 100% owned by hamelin gully pty ltd and are in good standing ·      a native title mining access agreement is in place between hamelin gully and the wilyakali traditional owners. a 1% over riding royalty is in place between hamelin gully and david clarke, ·      exploration done by other parties ·      acknowledgment and appraisal of exploration by other parties. ·      a multitude of historic explorers have undertaken exploration over the area. ·      pacmag, giralia, lynas, dominion, panda and hamelin gully have completed a number of geophysical, surface and drillhole exploration programs across the tenement package. the tenement package has also had government exploration undertaken over the netley hill, anabama hill and blue rose project areas. exploration has primarily been focused on porphyry- skarn copper and gold mineralization. iron ore exploration has been undertaken on the periphery of the exploration package geology ·      deposit type, geological setting and style of mineralisation. ·      mineralisation is associated with the anabama granite and adjacent adelaidean metasediments within the nackara arc of the delamerian orogen. ·      deposit styles include: ·      porphyry cu-mo systems with greisen overprint hosted within the granite. ·      skarn and replacement (manto-style) cu-au mineralisation developed in carbonate metasediments proximal to intrusive contacts. ·      structurally controlled quartz-reef/orogenic gold styles within folded adelaidean sequences, analogous to the manna hill goldfield. ·      geological setting is characterised by early palaeozoic granite intrusion into adelaidean platform sediments, with contact-related alteration and deformation associated with the delamerian orogeny. ·      styles of mineralisation include disseminated and stockwork sulphides (chalcopyrite, pyrite, molybdenite), carbonate replacement/recrystallisation with sulphides, and quartz-sulphide reef systems in shear/fold settings   drillhole 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 drill hole collar o  elevation or rl (reduced level - elevation above sea level in metres) of the drill hole collar o  dip and azimuth of the hole o  down hole length and interception 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. ·      see appendix 3 ·      a full review and validation of all historic data is currently being undertaken prior to the full report of all historic data. 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 calculated as length weighted averages. ·      only metal equivalent values were applied within the cross section (figure 4) to simplify overlapping intersections. the formula applied does not include metal recoveries and is therefore not a true representation of mineral economics. applied formula is: ·      cueq% = cu% + ((au (g/t) x (us$3,000/31.10348) / (us$9,000/100)) + ((mo % x (us$40,000/100) / ($9,000/100)) 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 (eg 'down hole length, true width not known'). ·      intercept lengths are oblique to mineralization with downhole lengths reported only ·      further review of historic data is required before determining true drillhole 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. ·      relevant diagrams have been included in the announcement. ·      exploration results are not being reported for existing mineral resources. ·      additional collar locations in diagrams reflect spatial location of historic data under review. 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. ·      significant intersections have been reported to highlight exploration potential of the project. upon completion of historic data review, further reporting of existing results will be reported 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 survey results; bulk samples - size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. ·      completion of historic exploration data is underway. all meaningful results will be released once the historic data review has been completed. further work ·      the nature and scale of planned further work (eg tests for lateral extensions or depth extensions or large-scale step-out drilling). ·      diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. ·      finalisation of historic data review. ·      planning for rc and diamond drilling at blue rose and netley hill prospects underway; drilling will aim to confirm geological interpretations and validate pervious intersections   appendix 3. collar locations of reported intersections   bhid easting northing elevation dip
