Wudinna Project Update

Maiden Rare Earth Resource Estimate - Unique and Unconstrained

Cobra, a gold, rare earth and IOCG exploration company focused on the Wudinna Project in South Australia, is pleased to announce a maiden Rare Earth Elements ("REE") JORC Mineral Resource Estimate ("MRE"), enabling a strategic baseline to advance an economically beneficial combination of gold and rare earth resources.

Highlights

· Maiden JORC MRE for the Wudinna Project clay-hosted REE of 20.9 Mt at 658 ppm Total Rare Earth Oxides ("TREO")

· The REE Mineral Resource occurs above and proximal to a defined 94,000 Oz gold resource at the Baggy Green prospect and overlies 500m of intersected gold mineralisation at the Clarke prospect, making this REE resource and future mining economics unique compared to other clay-hosted REE projects  

· The unique mineral occurrence will enable Cobra to investigate commercial outcomes for dual commodities

· Defined a sizeable REE Exploration Target at the Thompson prospect highlights the potential for substantial near-term resource growth

· Initial metallurgical testwork demonstrated magnet rare earth recoveries of up to 34.7%, whilst follow-up mineralogy and lithological testwork demonstrates potential for increased recoveries targeting ionic style mineralisation identified through pH conditions. Mapping and further analysis work will proof-test this concept, paving the way for resource re-classification and metallurgical upside

· Upside potential to tonnage and grade owing to downhole composite lengths of analysed samples across the Baggy Green prospect

· Estimation constrained by extent of current drilling, with extensions to be tested by planned drilling in coming months

Next Steps

The Company is funded to complete the following work scope to advance the Wudinna Project towards Feasibility evaluation:

· Metallurgical evaluation of a range of samples selected at varying pH conditions - an important catalyst for ionic REE adsorption

· Evaluate beneficiation and metallurgical optimisation processes to enable the development of a commercial flowsheet evaluation

· Further Scanning Electron Microscope ("SEM") analyses to evaluate quantities of REE mineral phases at various pH conditions

· A drilling programme of 5,000-10,000m scheduled to commence in March 2023, aimed at growing both gold and REE Mineral Resources at Clarke, Barns, and Thompson prospects

· Update to existing 211,000 Oz gold MRE to incorporate the Clarke prospect and over 5,000m of additional drilling undertaken across existing gold Mineral Resource prospects

Rupert Verco, CEO of Cobra, commented:

"Cobra has taken a fundamental step forward in its ambition to develop a globally unique mineral occurrence by defining a maiden Rare Earth Mineral Resource Estimate that overlies two growing gold prospects and is unconstrained.

Not only have we entered the peer group of Australian rare earth resource holders today, but uniquely we are approaching ours with the economic advantage of spatial proximity between rare earths and gold. Much of the spatial occurrence of the rare earth resource overlies gold mineralisation within the saprolite zone where, should the economics permit open cut mining methods for gold extraction, we would mine through the defined rare earth resource, effectively creating value from overburden. The Company considers the dual mineral occurrences as a globally unique opportunity to devise an environmentally considerate, low waste ratio, high value resource.

With only limited drilling undertaken to establish this baseline MRE, the expansion potential given the unconstrained mineralisation is compelling. The Exploration Target at the Thompson prospect to be drilled in the coming weeks is of particular interest and could rapidly expand the MRE. 

This exceptional result now enables Cobra to advance metallurgical testwork, grow dual Mineral Resources and commence strategic discussions aimed at project advancement. Cobra is now poised to expand both gold and rare earth resources through its 2023 exploration activities to advance the project towards feasibility studies."

The maiden REE MRE is set out in table 1 below:

Rare Earth Mineral Resources reported at a cut-off grade of 320 ppm TREO-Ce

¹ The conceptual quantity and grade of the Thompson Exploration Target is conceptual in nature, as there has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource. Consistent with this, all tonnages and grades are approximations. The Exploration Target is based on wide-spaced drilling completed to date.

The Wudinna Project comprises a number of shallow, camp scale gold occurrences. The alteration mineralogy and structural genesis associated with the gold mineralisation event is believed to act as a catalyst for REE enrichment and mobilisation. The spatial proximity of rare earth mineralisation has the potential to economically complement the gold mineralisation. Additional gold mineralisation has been defined outside of the existing gold MRE, particularly at Clarke where over 500m of mineralised strike has been defined and remains an exploration priority to increase the mineral inventory.

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.

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 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.

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 ionic 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 north-south 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

Figure 3 : Proposed geological model for gold and REE mineralisation at the Clarke and Baggy Green prospects

X-Ray Diffraction analysis performed by the Commonwealth Scientific and Industrial Research Organisation supports that a component of REE bursary is adsorbed to the primary clay particles, being kaolin and montmorillonite, in similar fashion to the highly desirable Ion Adsorbed Clay hosted deposits of southern China.

SEM analyses performed by the University of South Australia determined that:

· Primary REE mineral phases in basement, hard rock lithologies are zircon, titanite, apatite, andradite, epidote

·     Secondary REE mineral phases within the lower saprock (weakly to moderately weathered basement) are monazite, basanite, allanite, rutile

Figures 4-6 : SEM imagery of samples from 27, 47 and 117m downhole of CBRC0042

· REE enrichment in source rock is associated with Hiltaba intrusive alteration, the primary gold mineralising event

· Elevated phosphate is identified at the base of saprolite, however the peak is not associated with elevated REE grades (Figure 7)

Figure 7 : REE grades downhole of CBRC0042 intersected 8.2m at 561 ppm TREO from 38.1m below surface, and 19m at 0.79 g/t gold from 83m, including 5m at 2.62 g/t gold from 95m

· Definitive change in REE bearing mineral phases between basement and saprolite, demonstrated by the calculated mass abundance of respective REE mineral phases

· Rare Earth grade peaks in the upper saprolite occur where secondary REE phases are low, supporting clay adsorption

The identified changes in mineral phase from hard rock to lower saprock and the occurrence of grade peaks within the weathered saprolite with very low identifiable rare earth mineral phases is supportive of a component of the REE bursary being adsorbed to clay particles and is analogous to the ionic rare earth deposits of Southern China.

Drilling Techniques

The Mineral Resource Estimate is based upon the drill results or re-analysis of 204 drillholes (14,509m) that consist of aircore, rotary hammer, reverse circulation (RC) and a single diamond drillhole. 36 RC and 34 aircore holes have been drilled by Cobra since 2019. All rare earth results incorporated within the Mineral Resource Estimate were announced during 2022.

The drillhole spacing within the Mineral Resource area is generally 200m by 200m, however, areas of tighter drilling and sampling occur proximal to gold mineralisation where drill density is up to 25m by 100m.

The drilling and subsequent estimation which informs the Thompson Exploration Target of 81-223 Mt is based on drill traverses of 1 km spacing and drillhole line spacings of 200m. The potential quantity and grade of the Exploration Target is conceptual in nature as there has been insufficient exploration to estimate a Mineral Resource, however, the framework of drilling at Thompson provides the potential to yield a future resource.

Sampling and Sub-sampling Techniques

Downhole sample composites vary over the Mineral Resource, with historic drilling and subsequent re-analysis being performed on pulp samples from 1, 2, 4 and 6m down-hole intervals. Samples from Cobra's drilling have produced 1m composites from RC drilling and 2m from aircore drilling. Owing to the variable nature of REE mineralisation through the saprolite, greater composite lengths are expected to understate grade.

Sample Analysis Methods

Samples were submitted to Genalysis Intertek 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, Na, Nd, Pr, Sc, Sm, Tb, Th, Tm, U, Y and Yb.

Mineral Resource Estimation and Classification

The Mineral Resource has been estimated by independent consultants to the Company: Snowden Optiro.

The resource model for the REE mineralisation at Clarke and Baggy Green was constructed using a parent block size of 25 mE by 40 mN on 1 m benches and the parent blocks were allowed to sub-cell down to 5 mE by 10 mN by 0.5 mRL to more accurately represent the geometry and volume of the saprolite and saprock domains. Categorical indicator kriging (CIK) at the sub-cell resolution was used to define REE mineralised (>100 ppm CeO₂) blocks. The REE block grades were estimated using ordinary kriging. All REE (La₂O₃, CeO₂, Pr₆O₁₁, Nd₂O₃, Sm₂O₃, Eu₂O₃, Gd₂O₃, Tb₄O₇, Dy₂O₃, Ho₂O₃, Er₂O₃, Tm₂O₃, Yb₂O₃, Lu₂O₃ and Y₂O₃) were estimated independently.

The Mineral Resources have been classified as Inferred on the basis of confidence in geological and grade continuity and taking into account data quality, data density and confidence in the grade estimation, using the modelled grade continuity. In places the drillhole density is sufficient to support a higher Mineral Resource classification and scope exists to review the current Mineral Resource classification if positive results are obtained from additional metallurgical studies that support economic viability.

Density

Density was measured for 19 saprolite samples from diamond drilling at the Baggy Green and Barns gold Prospects that exhibit a range of densities between 1.2 t/m³ and 2.01 t/m³. The average density of 1.6 t/m³ was applied for tonnage estimation.

Cut-off Grade

The Mineral Resource has been reported above a cut-off grade of TREO-Ce of 320 ppm and assumes extraction by open pit mining.  The cut-off grade was selected based on the evaluation of other advanced clay hosted rare earth Mineral Resources and the consideration that future economic analysis of the cut-off grade is likely to incorporate parameters that support extraction of the underlying gold mineralisation.

Metallurgy

· Preliminary metallurgical test work focusing on extraction techniques adopted to ionic phase mineralisation using H₂SO₄ as a lixiviant, and performed by Australia's Nuclear Science and Technology Organisation, yielded recoveries of up to 34% Total Rare Earth Element ("TREE") from samples across two holes at Clarke

· Preliminary metallurgical testwork has provided positive indications that REE bursary is bound to clay particles. The identification of a technique or techniques to optimally recover rare earth metals from the saprolite mineralisation is ongoing with further desorption and leach testing underway

· pH testing of drill samples demonstrates variable conditions across all Prospects, saprolite horizons, and types of clays that are associated with high REE adsorption capacity

· The nature of the bonds which adsorb the REEs within enclosing clay appear dependent upon the local chemical environment:

o  Where local pH is greater than optimal (moderately alkaline), colloidal bonding is more abundant and a positive cerium anomaly is generally present

o  Where local pH is in an optimal range, ionic bonding appears favoured, the valuable MREO mineral suite is enhanced (pH 5-6.8), and REE baskets generate negative cerium anomalies

o  Where local pH is lower than optimal (acidic), REEs appear to have remained mobile and enhanced grades are not retained within the saprolite zone 

Figure 11 : pH analysis of 86 downhole composites at Clarke demonstrating grade peaks at acidity and alkaline conditions that support ionic adsorption of REE to clay particles

· pH testwork completed to date provides an encouragement that it can be utilised as a process to identify metallurgical upside

· REE grade is considerably higher at pH conditions 6-7 and 9-10. Should further metallurgical testing support a higher component of ionic adsorption, then saprolite acidity will be a key identifier for determining higher grades and zones amenable to lower processing costs

Appendix 1: JORC Code, 2012 Edition - Table 1

The table below summaries the assessment and reporting criteria used for the Clarke and Baggy Green REE Mineral Resource estimate and reflects the guidelines in Table 1 of The Australasian Code for the Reporting of Exploration Results, Mineral Resources and Ore Reserves (the JORC Code, 2012).

Section 1 Sampling Techniques and Data

Criteria	JORC Code explanation	Commentary
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 - onward · 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.
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).	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- onward · 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.

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 Google Pixel 6 mobile phone utilising the Avenza Map app. Collar points recorded with a horizontal accuracy within 5 m. · 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. · 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.	· The REE mineralisation is expected to be controlled by vertical weathering profiles. · Vertical drill holes are expected to be perpendicular to rare earth mineralisation. · It is not expected that the angled RC holes have introduced any bias to the rare earth mineralisation interpretation. · Drilling results are presented as true width.

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.	· This MRE is located within 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 changes with varying saprolite acidity and REE abundances support that a component of REE bursary is ionically adsorbed to clays.
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. · 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.

Appendix 3: Section 3 Estimation and Reporting of Mineral Resources

Criteria	JORC Code explanation	Commentary
Database integrity	· Measures taken to ensure that data has not been corrupted by, for example, transcription or keying errors, between its initial collection and its use for Mineral Resource estimation purposes. · Data validation procedures used.	· The drillhole database is managed in-house by Cobra Resources using the Company's Seequent MXDeposit database. · It has been validated by MXDeposit specialists and Cobra Resources. · Data has been imported from current and historical data files. · Source data for historical drilling has been verified as being drilled by Andromeda Metals and imported directly from their Datashed database. · Additional data validation, by Snowden Optiro, included checking for out of range assay data and overlapping or missing intervals.
Site visits	· Comment on any site visits undertaken by the Competent Person and the outcome of those visits.	· Mrs C Standing (Snowden Optiro, acting as Competent Person) has not visited the Wudinna Gold Project.
Geological interpretation	· Confidence in (or conversely, the uncertainty of) the geological interpretation of the mineral deposit. · Nature of the data used and of any assumptions made. · The effect, if any, of alternative interpretations on Mineral Resource estimation. · The use of geology in guiding and controlling Mineral Resource estimation. · The factors affecting continuity both of grade and geology.	· REE mineralisation at Clarke and Baggy Green is within saprolite and saprock horizons. There is reasonable confidence in the geological interpretation of these horizons within the Mineral Resource area. · The saprolite and saprock horizons were interpreted from geological logging data using Leapfrog Geo software.
Dimensions	· The extent and variability of the Mineral Resource expressed as length (along strike or otherwise), plan width, and depth below surface to the upper and lower limits of the Mineral Resource.	· The area used to constrain the Mineral Resource (that is within 50 m of the drilling) extends for 1.5 km east-west by 3 km north-south. The mineralisation is contained within a horizon of weathered saprolite and saprock that has a thickness ranging from 1 to 69 m and an average thickness of 36 m. The top of this horizon extends from surface to 24 m.
Estimation and modelling techniques	· The nature and appropriateness of the estimation technique(s) applied and key assumptions, including treatment of extreme grade values, domaining, interpolation parameters and maximum distance of extrapolation from data points. If a computer assisted estimation method was chosen include a description of computer software and parameters used.	· Data analysis and estimation was undertaken using Snowden Supervisor and Datamine software. · REE block grades were estimated using ordinary kriging (OK). Snowden Optiro considers OK to be an appropriate estimation technique for this type of mineralisation. · The drillhole spacing within the Mineral Resource area is generally 200 m by 200 m, however, areas of tighter drilling and sampling occur proximal to gold mineralisation where drill density is up to 25 m by 100 m. · A maximum extrapolation distance of 50 m was applied around the drilled area. · Almost 61% of the La and Ce assay data within domains is from samples of ≤1 m intervals, 24% is from intervals of >1 m to 2 m and 15% is from intervals of >2 to 6 m. The data was composited to 1 m intervals for statistical analysis and grade estimation. · Statistical analysis indicated that outlier grades are not present and top-cutting (grade-capping) was not applied. · Variogram analysis was undertaken to determine the kriging estimation parameters used for OK estimation of each REE. · Variogram analysis was undertaken for each REE within the saprolite and saprock. Within the mineralised area of the saprolite maximum continuity ranges are 95 to 420 m E-W and 54 m to 166 m N-S. Within the saprock maximum continuity ranges are 100 to 280 m NE-SW and 295 m to 450 m NW-SE. · Kriging neighbourhood analysis was performed to determine the block size, sample numbers and discretisation levels. · Three estimation passes were used in block grade estimation; the first search was based upon the La 2 O 3 variogram ranges; the second search was two times the initial search and the third search was up to five times the initial search . The second and third search es had reduced sample numbers required for estimation.  Almost 55 % of the total block grades were estimated in the first search pass, 34 % within the second search pass and the remaining 11% estimated in the third search pass.
	· Description of how the geological interpretation was used to control the resource estimates.	· Geological interpretations of the top of basement, saprock and saprolite horizons and the transported cover sediments were completed using Leapfrog Geo software.  3D interpretations of the saprock and saprolite were used to constrain the Mineral Resource estimate. · Categorical indicator kriging (CIK) at the sub-cell resolution was used to define REE mineralised (>100 ppm CeO2) blocks within the saprolite horizon. · The mineralised domains are considered geologically robust in the context of the resource classification applied to the estimate.
	· The availability of check estimates, previous estimates and/or mine production records and whether the Mineral Resource estimate takes appropriate account of such data.	· Mineral Resources have not previously been reported for this deposit area and no production has occurred.
	· The assumptions made regarding recovery of by-products.	· No assumptions have been applied for the recovery of by-products.
	· Estimation of deleterious elements or other non-grade variables of economic significance (e.g. sulphur for acid mine drainage characterisation).	· Deleterious elements were not considered for the Mineral Resource estimate.
	· In the case of block model interpolation, the block size in relation to the average sample spacing and the search employed.	· Grade estimation was into parent blocks of 25 mE by 40 mN by 1mRL.  · Block dimensions were selected from kriging neighbourhood analysis and reflect the variability of the deposit as defined by the current drill spacing. · Sub-cells to a minimum dimension of 5 mE by 10 mN by 0.5 mRL were used to represent volume. · The drillhole spacing within the Mineral Resource area is generally 200 m by 200 m, however, areas of tighter drilling and sampling occur proximal to gold mineralisation where drill density is up to 25 m by 100 m. · Search ellipse dimensions were selected from variogram analysis of L2O3.
	· Any assumptions behind modelling of selective mining units.	· Selective mining units were not modelled.
	· Any assumptions about correlation between variables.	· The REEs have moderate to high correlation coefficients (0.68 to 0.99). · All REEs ( La2O 3 , CeO 2 , Pr6O11 , Nd2O3 , Sm2O3 , Eu2O3 , Gd2O3 , Tb4O7 , Dy2O3 , Ho2O3 , Er2O3 , Tm2O3 , Yb2O3 , Lu2O3 and Y2O3 ) were estimated independently.
	· The process of validation, the checking process used, the comparison of model data to drillhole data, and use of reconciliation data if available.	· The estimated block model grades were: o  visually validated against the input drillhole data o  comparisons were carried out against the declustered drillhole data and by northing, easting and elevation slices. o  global statistical comparisons were carried out between the mean input sample grade with the estimated block grade for each domain (saprock and the mineralised and low grade REE domains in the saprolite). · No production has taken place and thus no reconciliation data is available.
Cut-off parameters	· The basis of the adopted cut-off grade(s) or quality parameters applied.	· The Mineral Resource has been reported above a cut-off grade of TREO-Ce of 320 ppm and assumes extraction by open pit mining. · This cut-off grade was selected based on the evaluation of other advanced clay hosted rare earth Mineral Resources and the consideration that future economic analysis of the cut-off grade is likely to incorporate parameters that support extraction of the underlying gold mineralisation.
Mining factors or assumptions	· Assumptions made regarding possible mining methods, minimum mining dimensions and internal (or, if applicable, external) mining dilution. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential mining methods, but the assumptions made regarding mining methods and parameters when estimating Mineral Resources may not always be rigorous.	· Planned extraction is by open pit mining.  · Mining factors such as dilution and ore loss have not been applied.
Metallurgical factors or assumptions	· The basis for assumptions or predictions regarding metallurgical amenability. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential metallurgical methods, but the assumptions regarding metallurgical treatment processes and parameters made when reporting Mineral Resources may not always be rigorous.	· Preliminary work performed by Metallurgical Test Work performed by the Australian Nuclear Science and Technology Organisation (ANSTO) demonstrated recovery potential via desorption/leaching conditions where: · At pH4, 0.5M (NH4)2SO4 as lixiviant REE recoveries were generally below 10% · At pH1, (NH4)2SO4 as lixiviant recoveries increased with leach period. At 6 hours recoveries up to 34.7% were achieved. · Subsequent mineralogy and acidity testing has identified zones that are likely to have a higher component of ionic adsorption and are therefore likely to lead to higher recoveries. · The samples submitted were from gold bearing holes, the pH conditions do not fit the criteria for REDOX controlled ion adsorption.  · Further metallurgy testing is underway to validate these findings. · Metallurgy optimisation tests are being carried out on bulk samples by the University of South Australia.
Environmental factors or assumptions	· Assumptions made regarding possible waste and process residue disposal options. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider the potential environmental impacts of the mining and processing operation.	· No assumptions have been made regarding waste and process residue.
Bulk density	· Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples. · The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and differences between rock and alteration zones within the deposit. · Discuss assumptions for bulk density estimates used in the evaluation process of the different materials.	· Average values have been calculated from the dataset. · Bulk density measurements were calculated by water displacement method. Samples from the saprolite zone were wrapped in cling film before testing. · Density was measured for 19 samples from the saprolite zone. Values range from 1.26 t/m3 to 2.1 t/m3, with an average 1.6 t/m3. The average of 1.6 t/m3 was used for tonnage estimation.
Classification	· The basis for the classification of the Mineral Resources into varying confidence categories. · Whether appropriate account has been taken of all relevant factors (i.e. relative confidence in tonnage/grade estimations, reliability of input data, confidence in continuity of geology and metal values, quality, quantity and distribution of the data). · Whether the result appropriately reflects the Competent Person's view of the deposit.	· The Mineral Resources have been classified as Inferred on the basis of confidence in geological and grade continuity and taking into account data quality, data density and confidence in the grade estimation, using the modelled grade continuity. · The assigned classification of Inferred reflects the Competent Person's assessment of the accuracy and confidence levels in the Mineral Resource estimate.
Audits or reviews	· The results of any audits or reviews of Mineral Resource estimates.	· The Mineral Resource has been reviewed internally as part of normal validation processes by Snowden Optiro. · No external audit or review of the current Mineral Resource has been conducted.
Discussion of relative accuracy/ confidence	· Where appropriate a statement of the relative accuracy and confidence level in the Mineral Resource estimate using an approach or procedure deemed appropriate by the Competent Person. · The statement should specify whether it relates to global or local estimates, and, if local, state the relevant tonnages, which should be relevant to technical and economic evaluation.	· The assigned classification of Inferred reflects the Competent Person's assessment of the accuracy and confidence levels in the Mineral Resource estimate.  · The statement relates to global estimates of tonnes and grade. · No production data exists for the Wudinna Project gold or REE deposits.
