Drilling Defines REE Resource Extension Potential

Cobra, a gold, rare earth and IOCG exploration company focused on the Wudinna Project in South Australia, announces rare earth results from Reverse Circulation ("RC") and Aircore ("AC") drilling, which will support further Rare Earth Elements ("REE") resource growth at the Company's unique and complementary gold and REE resource.

Drilling results demonstrate significant potential for resource extensions in multiple directions, with intervals up to 25m and Total Rare Earth Oxides ("TREO") grades of up to 3,568 ppm. Results will be incorporated in a rare earth mineral resource update, which is scheduled to be published once the update to the existing gold Mineral Resource Estimate ("MRE") has been completed, expected in the second half of the year.

Highlights:

·    CBAC0134: 18m at 1,123 ppm TREO from 21m, where the Magnet Rare Earth Oxide ("MREO") equates to 21% of the TREO, including 3m at 3,568 ppm TREO, where the MREO equates to 21%

·    CBAC0109: 25m at 739 ppm TREO from 12m, where the MREO equates to 26%, including 9m at 1,187 ppm TREO, where the MREO equates to 28%

·    CBAC0114: 21m at 736 ppm TREO from 15m, where the MREO equates to 24%, including 3m at 1,298 ppm TREO, where the MREO equates to 22%

·    CBAC0147: 9m at 977 ppm TREO from 12m, where the MREO equates to 19%, including 3m at 1,719 ppm TREO, where the MREO equates to 19%

·    CBAC0102: 4m at 831 ppm TREO from 14m, where the MREO equates to 28%

·    CBAC0135: 3m at 1823 ppm TREO from 18m, where the MREO equates to 22%

·    At the Bradman prospect, rare earth enrichment occurs directly in contact with palaeo-channel sediments, where the presence of reduced organic material has the potential to increase the ionic component of mineralisation. Highlight intersections include:

o  CBAC0158: 15m at 946 ppm TREO from 33m, where the MREO equates to 24%, including 3m at 1,687 ppm TREO, where the MREO equates to 22%

o  CBAC0156: 15m at 825 ppm TREO from 45m, where the MREO equates to 25%, including 3m at 1,417 ppm TREO, where the MREO equates to 25%

o  CBAC0149: 9m at 897 ppm TREO from 54m, where the MREO equates to 23%, including 6m at 1,076 ppm TREO, where the MREO equates to 23%

·    These results represent 43 of 95 drilled AC holes. Further results from resource expansion drilling and testing of palaeo-channel clays at the Boland prospect remain outstanding

·    Selected samples from this drilling will be used to further advance REE metallurgical studies aimed at defining a viable flow sheet for extraction

Rupert Verco, CEO of Cobra, commented:

"These drilling results confirm the resource growth potential of our unique rare earth resource and will likely inform a significant resource update, establishing Wudinna as a potential tier-1 rare earth project whose unique proximity to gold mineralisation has the potential to contribute favourably to economics.

"Whilst we eagerly await further drilling results, our focus turns to metallurgical advancement where our progress in mineralogical and ore body characterisation has provided the essential information required to advance recoveries, targeting low cost and environmentally considerate processes.

"The results also come at a time when the necessity of critical minerals has been further highlighted through the signing of the Climate, Critical Minerals and Clean Energy Transformation Compact between Australia and the US. It is our ambition to advance the project to capitalise on the opportunities that shall arise from this strategic partnership."

About Cobra

Cobra is defining a unique multi-mineral resource at the Wudinna Project in South Australia's Gawler Craton, a tier one mining and exploration jurisdiction which hosts several world-class mines. Cobra's Wudinna tenements, totalling 3,261 km², contain extensive orogenic gold mineralisation and are characterised by potentially open-pitable, high-grade gold intersections, with ready access to infrastructure. Cobra has 22 orogenic gold targets outside of the current 211,000 Oz gold JORC Mineral Resource Estimate. In 2021, Cobra discovered rare earth mineralisation proximal to and above the gold mineralisation which has been demonstrated to be regionally scalable. In 2023, Cobra published a maiden rare earth JORC Mineral Resource Estimate of 20.9 Mt at 658 ppm Total Rare Earth Oxides enabling a strategic baseline to advance an economically beneficial combination of gold and rare earth resources.

o  CBAC0139: 13m at 698 ppm TREO from 24m, where the MREO equates to 21%

·    Baggy Green West, where results from two of six holes drilled tested demagnetised zones that demonstrate increased saprolite horizons prospective for REE resource extensions, as supported by:

o  CBAC0135: 3m at 1,823 ppm TREO from 18m, where the MREO equates to 22%

o  CBAC0134: 18m at 1,123 ppm TREO from 21m, where the MREO equates to 21%, including 3m at 3,568 ppm TREO from 24m, where the MREO equates to 21%

·    Bradman, where 11 holes have verified the electromagnetic interpretation of an extensive palaeo-drainage system. Here, the channel sediments are more oxidised and clay intervals limited, and REE mineralisation is enriched on the contact to the palaeo-sediments, where the following intersections are present:

o  CBAC0147: 9m at 977 ppm TREO from 12m, where the MREO equates to 19%, including 3m at 1,719 ppm TREO from 12m, where the MREO equates to 19%

o  CBAC0159: 6m at 637 ppm TREO from 54m, where the MREO equates to 23%

·    Boland, where 20 holes validate the presence of significant palaeo-drainage system where smectite clays occur within 5-15m interbeds of oxidised and reduced channel sands. The presence of abundant lignite (organic matter) is a positive sign for chemical reduction and subsequent adsorption of REEs. Results are anticipated over the next two to four weeks

·    Barns East, where 10 holes were drilled to test and infill previous drilling, intersecting shallow gold mineralisation that lies outside of the existing Barns MRE, where historical intersections include:

o  7m at 2.23 g/t gold from 52m, including 1m at 8.3 g/t gold from 57m

o  6m at 1.35 g/t gold from 64m

o  7m at 1.35 g/t gold from 64m

o  5m at 1.00 g/t gold from 10m

·    AC drilling failed to penetrate a silicious quartzite unit and intersect basement. Regardless, this drilling has defined an anomalous zone of North-South gold mineralisation through the following anomalous gold mineralisation in the upper saprolite:

o  CBAC0092 intersected 2m at 0.19 g/t gold from 8m and 2m at 1 g/t from 10m

Location and Land Tenure

The Wudinna Project is located on the northern Eyre Peninsula, within South Australia, a tier 1 mining jurisdiction. The defined dual Gold and REE MRE occurs within EL6131 (Corrobinnie) and lies within the Pinkawillinie Conservation Park (dual proclamation land). Gold Resources extend across EL5953 (Minnipa) and EL6131. The tenements are held by Peninsula Resources, a subsidiary of Andromeda Metals. In April 2023, the Company announced its 75% earn-in had been recognised by Andromeda Metals under the terms of the Wudinna Heads of Agreement.

Geology and Nature of the REE Mineralisation

The gold and REE deposits at the Wudinna Project are considered to be related to the structurally controlled basement weathering of epidote-pyrite alteration related to the 1590 Ma Hiltaba/GRV tectonothermal event of the Gawler Craton. Gold and REE mineralisation have a spatial association with mafic intrusions/granodiorite alteration and are associated with metasomatic alteration of host rocks. Epidote alteration associated with gold mineralisation is REE enriched and believed to be the primary source.

The REE mineralisation is regionally extensive in weathered (saprolite and saprock) zones developed on basement rocks. The nature of controlling structures that act as conduits for gold mineralisation are also thought to act as catalysts for the secondary processes that promote weathering and subsequent mobilisation of REEs to the saprolite and saprock.

The following simplified model is proposed for clay-hosted REEs and the Clarke and Baggy Green prospects:

·    Gold and sulphide mineralisation is directly associated with Hiltaba Suite volcanics (~1590-1575 Ma)

·    WNW redial shears under NS compression (craton emplacement) act as dilatational conduits through Kimbian and Sleaford age granitoids

·    Hiltaba suite mafics are enriched in light REEs

·    Gold and sulphide mineralisation forms along sheeted granitoid "dome" joints, bound within shear zones

·    Sericite and epidote alteration halos form peripheral to gold mineralisation

·    Epidote alteration is enriched in REEs providing an enriched source

·    Supergene enrichment of gold occurs at the base of oxidation, where the weathering of primary sulphides generates acidic conditions

·    Primary REE phases are weathered to secondary REE phases through prolonged weathering

·    Acidic conditions generated by the weathering of sulphides re-mobilises REEs

·    Near redox boundaries (pH 6-7) a greater component of REE is absorbed to clay particles

·    Colloidal phases occur as conditions become alkaline

Sampling techniques	·    Nature and quality of sampling (eg 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 (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.	Pre 2021 ·      Historic RC and RAB drilling methods have been employed at Clarke and Baggy Green Prospects since 2000. ·      Pulp samples from pre-Cobra Resources' drilling were collected with intervals of      1-6 m. Samples were riffle split if dry or sub split using a trowel if wet. ·      Pulp samples were obtained from Challenger geological services using a combination of logging and geochemical selection criteria. Samples pulled from storage were re-pulverised at the laboratory prior to further analysis. 2021 - 2022 ·      Sampling during Cobra Resources 2022 aircore ("AC") drilling programme at all Prospects were obtained through AC drilling methods. ·      2 m samples were collected in 20l buckets via a rig mounted cyclone. An aluminum scoop was used to collect a 2-4 kg sub sample from each bucket. Samples were taken from the point of collar, but only samples from the commencement of saprolite were selected for analysis. ·      Samples submitted to the Genalysis Intertek Laboratories, Adelaide and pulverised to produce the 25g fire assay charge and 4 acid digest sample. ·      A summary of previous RC drilling at the Wudinna Project is outlined in the Cobra Resources' RNS number 7923A from 7 February 2022. 2023 RC ·      Samples were collected via a Metzke cone splitter mounted to the cyclone. 1m samples were managed through chute and butterfly valve to produce a 2-4 kg sample. Samples were taken from the point of collar, but only samples from the commencement of saprolite were selected for analysis. ·      Samples submitted to  Bureau Veritas Laboratories, Adelaide, and pulverised to produce the 50 g fire assay charge and 4 acid digest sample. AC ·      A combination of 2m and 3 m samples were collected in green bags via a rig mounted cyclone. An PVC spear was used to collect a 2-4 kg sub sample from each green bag. Samples were taken from the point of collar. ·      Samples submitted to  Bureau Veritas Laboratories, Adelaide, and pulverised to produce the 50 g fire assay charge and 4 acid digest sample.

Pre 2021 ·      Drill methods include AC, RH and RAB in unconsolidated regolith and aircore hammer in hard rock.  Some shallow RC holes have been drilled in place of AC and RAB, a single diamond drillhole has been incorporated in the estimate. 2021- 2022 ·      Drilling completed by McLeod Drilling Pty Ltd using 75.7 mm NQ air core drilling techniques from an ALMET Aircore rig mounted on a Toyota Landcruiser 6x6 and a 200psi, 400cfm Sullair compressor. ·      Slimline RC drilling was completed by Wuzdrill pty limited and Indicator drilling services Pty Ltd using a 400D and Mantis C60R drill rigs using a 4" hammer and 78mm drill rods.  2023 ·      Drilling completed by Bullion Drilling Pty Ltd using 5 ¾" reverse circulation drilling techniques from a Schramm T685WS rig with an auxiliary compressor. ·      Drilling completed by McLeod Drilling Pty Ltd using 75.7 mm NQ air core drilling techniques from an ALMET Aircore rig mounted on a Toyota Landcruiser 6x6 and a 200psi, 400cfm Sullair compressor.
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.	·      Sample recovery was generally good.All samples were recorded for sample type, quality and contamination potential and entered within a sample log. ·      In general, sample recoveries were good with 10 kg for each 1 m interval being recovered from AC drilling. ·      No relationships between sample recovery and grade have been identified.  ·      RC drilling completed by Bullion Drilling Pty Ltd using 5 ¾" reverse circulation drilling techniques from a Schramm T685WS rig with an auxiliary compressor ·      Sample recovery for RC was generally good. All samples were recorded for sample type, quality and contamination potential and entered within a sample log. ·      In general, RC sample recoveries were good with 35-50 kg for each 1 m interval being recovered. ·      No relationships between sample recovery and grade have been identified.

Lithology, colour, weathering and moisture were documented. ·      Logging is generally qualitative in nature. ·      All drill metres have been geologically logged on sample intervals (1-3 m).
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.	Pre-2021 ·      Samples from AC, RAB and "bedrock" RC holes have been collected initially as 6 m composites followed by 1 m re-splits.  Many of the 1 m re-splits have been collected by riffle splitting. ·      RC samples have been collected by riffle splitting if dry, or by trowel if wet ·      Pulverised samples have been routinely checked for size after pulverising ·      Pulp samples were re- pulverised after storage to re-homogenise samples prior to analysis. 2021-onward ·      The use of an aluminum scoop or PVC spear to collect the required 2-4 kg of sub-sample from each AC sample length controlled the sample volume submitted to the laboratory. ·      Additional sub-sampling was performed through the preparation and processing of samples according to the lab internal protocols. ·      Duplicate AC samples were collected from the green bags using an aluminium scoop or PVC spear at a 1 in 25 sample frequency. ·      Sample sizes were appropriate for the material being sampled. ·      Assessment of duplicate results indicated this sub-sample method provided good repeatability for rare earth elements. ·      RC drill samples were sub-sampled using a cyclone rig mounted splitter with recoveries monitored using a field spring scale. ·      Manual re-splitting of RC samples through a riffle splitter was undertaken where sample sizes exceeded 4 kg. ·      RC field duplicate samples were taken nominally every 1 in 25 samples. These samples showed good repeatability for REE.
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 were submitted to Bureau Veritas Laboratories, Adelaide for preparation and analysis. ·      Multi element geochemistry were digested by four acid ICP-MS and analysed for Ag, Ce, Cu, Dy, Er, Eu, Gd, Ho, La, Lu, Mg, Na, Nd, P, Pr, Sc, Sm, Tb, Th, Tm, U, Y and Yb. ·      Field gold blanks and rare earth standards were submitted at a frequency of 1 in 25 samples. ·      Field duplicate samples were submitted at a frequency of 1 in 25 samples ·      Reported assays are to acceptable levels of accuracy and precision. ·      Internal laboratory blanks, standards and repeats for rare earths indicated acceptable assay accuracy.
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.	·      Sampling data was recorded in field books, checked upon digitising and transferred to database. ·      Geological logging was undertaken digitally via the MX Deposit logging interface and synchronised to the database at least daily during the drill programme. ·      Compositing of assays was undertaken and reviewed by Cobra Resources staff. ·      Original copies of laboratory assay data are retained digitally on the Cobra Resources server for future reference. ·      Samples have been spatially verified through the use of Datamine and Leapfrog geological software for pre 2021 and post 2021 samples and assays. ·      Twinned drillholes from pre 2021 and post 2021 drill programmes showed acceptable spatial and grade repeatability. ·      Physical copies of field sampling books are retained by Cobra Resources for future reference. ·      Significant intercepts have been prepared by Mr Rupert Verco and reviewed by Mr Robert Blythman.
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.	Pre 2021 ·      Collar locations were pegged using DGPS to an accuracy of +/-0.5 m. ·      Downhole surveys have been completed for deeper RC and diamond drillholes ·      Collars have been picked up in a variety of coordinate systems but have all been converted to MGA 94 Zone 53. Collars have been spatially verified in the field. ·      Collar elevations were historically projected to a geophysical survey DTM. This survey has been adjusted to AHD using a Leica CS20 GNSS base and rover survey with a 0.05 cm accuracy. Collar points have been re-projected to the AHD adjusted topographical surface. 2021-onward ·      Collar locations were initially surveyed using a mobile phone utilising the Avenza Map app. Collar points recorded with a GPS horizontal accuracy within 5 m. ·      RC Collar locations were picked up using a Leica CS20 base and Rover with an instrument precision of 0.05 cm accuracy. ·      Locations are recorded in geodetic datum GDA 94 zone 53. ·      No downhole surveying was undertaken on AC holes. All holes were set up vertically and are assumed vertical. ·      RC holes have been down hole surveyed using a Reflex TN-14 true north seeking downhole survey tool or Reflex multishot ·      Downhole surveys were assessed for quality prior to export of data. Poor quality surveys were downgraded in the database to be excluded from export. ·      All surveys are corrected to MGA 94 Zone 53 within the MX Deposit database. ·      The quality and accuracy of the topographic control is considered sufficient for the Mineral Resource estimation and classification applied.
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.	·     Drillhole spacing was designed on transects 50-80 m apart. Drillholes generally 50-60 m apart on these transects but up to 70 m apart. ·     Additional scouting holes were drilled opportunistically on existing tracks at spacings 25-150 m from previous drillholes. ·     Regional scouting holes are drilled at variable spacings designed to test structural concepts ·     Data spacing is considered adequate for a saprolite hosted rare earth Mineral Resource estimation. ·     No sample compositing has been applied ·     Drillhole spacing does not introduce any sample bias. ·     The data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for interpretation of the REE mineralised horizon and the classification applied.
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.	·     RC drillholes have been drilled between -60 and -75 degrees at orientations interpreted to appropriately intersect gold mineralisation ·     Gold results are not presented as true width but are not considered to present any down-dip bias.
Sample security	·    The measures taken to ensure sample security.	Pre 2021 ·    Company staff collected or supervised the collection of all laboratory samples. Samples were transported by a local freight contractor ·    No suspicion of historic samples being tampered with at any stage. ·    Pulp samples were collected from Challenger Geological Services and submitted to Intertek Genalysis by Cobra Resources' employees. 2021-onward ·    Transport of samples to Adelaide was undertaken by a competent independent contractor. Samples were packaged in zip tied polyweave bags in bundles of 5 samples at the drill rig and transported in larger bulka bags by batch while being transported. ·    There is no suspicion of tampering of samples.

Appendix 2: 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.	·    RC drilling occurred on EL 6131, currently owned 100% by Peninsula Resources limited, a wholly owned subsidiary of Andromeda Metals Limited. ·    Alcrest Royalties Australia Pty Ltd retains a 1.5% NSR royalty over future mineral production from licenses EL6001, EL5953, EL6131, EL6317 and EL6489. ·    Baggy Green, Clarke, Laker and the IOCG targets are located within Pinkawillinnie Conservation Park. Native Title Agreement has been negotiated with the NT Claimant and has been registered with the SA Government. ·    Aboriginal heritage surveys have been completed over the Baggy Green Prospect area, with no sites located in the immediate vicinity. ·    A Native Title Agreement is in place with the relevant Native Title party.
Exploration done by other parties	·    Acknowledgment and appraisal of exploration by other parties.	·    On-ground exploration completed prior to Andromeda Metals' work was limited to 400 m spaced soil geochemistry completed by Newcrest Mining Limited over the Barns prospect. ·    Other than the flying of regional airborne geophysics and coarse spaced ground gravity, there has been no recorded exploration in the vicinity of the Baggy Green deposit prior to Andromeda Metals' work.
Geology	·    Deposit type, geological setting and style of mineralisation.	·    The gold and REE deposits are considered to be related to the structurally controlled basement weathering of epidote- pyrite alteration related to the 1590 Ma Hiltaba/GRV tectonothermal event. ·    Mineralisation has a spatial association with mafic intrusions/granodiorite alteration and is associated with metasomatic alteration of host rocks. Epidote alteration associated with gold mineralisation is REE enriched and believed to be the primary source. ·    Rare earth minerals occur within the saprolite horizon. XRD analysis by the CSIRO identifies kaolin and montmorillonite as the primary clay phases. ·    SEM analysis identified REE bearing mineral phases in hard rock: ·      Zircon, titanite, apatite, andradite and epidote. ·    SEM analyses identifies the following secondary mineral phases in saprock: ·      Monazite, bastanite, allanite and rutile. ·    Elevated phosphates at the base of saprock do not correlate to rare earth grade peaks. ·    Upper saprolite zones do not contain identifiable REE mineral phases, supporting that the REEs are adsorbed to clay particles. ·    Acidity testing by Cobra Resources supports that REDOX chemistry may act as a catalyst for Ionic and Colloidal adsorption. ·    REE mineral phase change with varying saprolite acidity and REE abundances support that a component of REE bursary is adsorbed to clays. ·    Palaeo drainage has been interpreted from historic drilling and re-interpretation of EM data that has generated a top of basement model.  ·    The conditions within the interpreted Palaeo system are considered supportive of ionic REE mineralisation.
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.	·    Exploration results are not being reported as part of the Mineral Resource area.
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.	·    Reported summary intercepts are weighted averages based on length. ·    No maximum/ minimum grade cuts have been applied. ·    No metal equivalent values have been calculated. ·    Gold results are reported to a 0.3 g/t cut-off with a maximum of 2m internal dilution with a minimum grade of 0.1 g/t Au. ·    Rare earth element analyses were originally reported in elemental form and have been converted to relevant oxide concentrations in line with industry standards.

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').	·    Preliminary results support unbiased testing of mineralised structures. ·    Previous holes have been drilled in several orientations due to the unknown nature of mineralisation. ·    Most intercepts are vertical and reflect true width intercepts. ·    Exploration results are not being reported for the Mineral Resource area.
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 the Mineral Resources area.
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.	·    Not applicable - Mineral Resource and Exploration Target are defined. ·    Exploration results are not being reported for the Mineral Resource area.
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.	·    Refer to previous announcements listed in RNS for reporting of REE results, metallurgical testing and detailed gold intersections.
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.	·    Infill and extensional drilling aimed at growing the Mineral Resource and converting Inferred Resources to Indicated Resources is planned.
