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 2023

· Historic Rotary Mud drilling targeting paleochannel hosted uranium was completed. Some residue samples were retained in the Tonsley Core Library, downhole geophysical logging was the primary data collected for these holes.

· Select historic sample residues over Boland were analysed as reported in RNS 1834M (26 April 2024)

2023

 Aircore

· A combination of 2m and 3m samples were collected in green bags via a rig mounted cyclone. A PVC spear was used to collect a 2-4kg sub sample from each green bag. Sampling commenced from the collar point with samples submitted for analysis from the top of saprolite.

· Samples were submitted to Bureau Veritas Laboratories, Adelaide and pulverized to produce a 4-acid digest sample.

2024

SONIC

· Drill results are outlined in RNS 0297I (25 March 2024)

· Core was scanned by a SciAps X555 pXRF to determine sample intervals. Intervals through mineralized zones were taken at 10cm. Through waste, sample intervals were lengthened to 50cm. Core was halved by knife cutting. XRF scan locations were taken on an inner surface of the core to ensure readings were taken on fresh sample faces.

· Samples were submitted to Bureau Veritas Laboratories, Adelaide and pulverized to produce a 4 acid digest sample.

Aircore

· 1m sample intervals of 2-4 kg were taken via PVC spear from green bags at the rig. All samples collected were submitted to the lab for analysis. From 0-6 m in each hole samples were composited to 3m.

· Samples were submitted to Bureau Veritas Laboratories, Adelaide and pulverized to produce a 4 acid digest sample.

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 2023

· Drill methods include Rotary Mud and AC

2023

· Drilling completed by McLeod Drilling Pty Ltd using 75.7mm NQ air core drilling techniques from an ALMET aircore rig mounted on a Toyota Landcruiser 6x6 and a 200psi, 400cfm Sullair compressor.

2024

· Sonic Core drilling completed Star Drilling using 4" core with a SDR12 drill rig. Holes were reamed to 6" or 8" to enable casing and screens to be installed

· Aircore Drilling completed by McLeod Drilling Pty Ltd using 75.7mm 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.

· Aircore Sample recovery is for the style of drilling. All samples were recorded for sample type, quality and contamination potential and entered within a sample log.

· In general, sample recoveries range between 5-10kg for each 1 m interval being recovered from AC drilling.

· Mineralisation occurs within a confined aquifer where ground water does influence sample recovery

· Mineralisation within the targeted Pidinga Formation is bound to fine, organic rich material, the potential loss of mineralized material from coarser host sands is possible

· Any grade bias is expected to be grade loss

· The potential loss of fine material is being evaluated by sizing fraction analysis and follow-up sonic core drilling where aircore holes will be twinned.

Sonic Core

· Sample recovery is considered excellent.

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.

· All drill samples were logged by a qualified geologist at the time of drilling. Lithology, colour, weathering and moisture were documented. All core drilled has been lithologically logged.

· 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 2023

· Historic Residue samples were generally 2m composites and were stored at the South Australian Drill Core Reference Library at Tonsley, a subsample of approximately 20g was removed for lab submission.

· Select samples of geological interest were selected for lab submission

· No QAQC samples were included in the submission of these samples. Sample results were intended to indicate mineralisation potential but would not be suitable for resource estimation

Post 2023

· A PVC spear was used to collect 2-4kg of sub-sample from each AC sample length controlled the sample volume submitted to the lab.

· Additional sub-sampling was performed through the preparation and processing of samples according to the Bureau Veritas internal protocols.

· Field duplicate AC samples were collected from the green bags using a PVC spear scoop at a 1 in 25 sample frequency.

· Sample sizes are considered appropriate for the material being sampled.

· Assessment of duplicate results indicated this sub - sample method provided appropriate repeatability for rare earths.

Sonic Drilling

· Field duplicate samples were taken nominally every 1 in 25 samples where the sampled interval was quartered.

· Blanks and Standards were submitted every 25 samples

· Half core samples were taken where lab geochemistry sample were taken.

· Internal lab blanks, standards and repeats for rare earths indicated acceptable assay accuracy.

Sample Characterisation Test Work performed by the Australian Nuclear Science and Technology Organisation (ANSTO)

· Full core samples were submitted to Australian Nuclear Science and Technology Organisation (ANSTO), Sydney for preparation and analysis. The core was split in half along the vertical axis, and one half further split into 10 even fractions along the length of the half-core. Additional sub-sampling, homogenisation and drying steps were performed to generate ~260 g (dry equivalent) samples for head assay according to the laboratory internal protocols.

· Multi element geochemistry of solid samples were analysed at ANSTO (Sydney) by XRF for the major gangue elements Al, Ca, Fe, K, Mg, Mn, Na, Ni, P, Si, S, and Zn.

· Multi element geochemistry of solid samples were additionally analysed at ALS Geochemistry Laboratory (Brisbane) on behalf of ANSTO by lithium tetraborate digest ICP-MS and analysed for Ce, Dy, Er, Eu, Gd, Ho, La, Lu, Nd, Pr, Sm, Tb, Th, Tm, U, Y and Yb.

· Reported assays are to acceptable levels of accuracy and precision.

Metallurgical Leach Test Work performed by the Australian Nuclear Science and Technology Organisation (ANSTO)

· ANSTO laboratories prepared ~80g samples for diagnostic leaches, a 443g sample for a slurry leach and a 660g sample for a column leach. Sub-samples were prepared from full cores according to the laboratory internal protocols. Diagnostic and slurry leaching were carried out in baffled leach vessels equipped with an overhead stirrer and applying a 0.5 M (NH4)2SO4 lixiviant solution, adjusted to the select pH using H2SO4.

· 0.5 M H2SO4 was utilised to maintain the test pH for the duration of the test, if necessary. The acid addition was measured.

· Thief liquor samples were taken periodically.

· At the completion of each test, the final pH was measured, the slurry was vacuum filtered to separate the primary filtrate.

· The thief samples and primary filtrate were analysed as follows:

o  ICP-MS for Ce, Dy, Er, Eu, Gd, Ho, La, Lu, Mn, Nd, Pb, Pr, Sc, Sm, Tb, Th, Tm, U, Y, Yb.

o  ICP-OES for Al, Ca, Fe, K, Mg, Mn, Na, Si.

· 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.

· Boland is located on EL5953, currently owned 100% by Peninsula Resources limited, a wholly owned subsidiary of Andromeda Metals Limited.

· In 2024, Cobra through its subsidiary Lady Alice Mines purchased the remaining ownership of the Wudinna Project tenements.

· An application through partial surrender is currently with the South Australian Government which will see LAM as the 100% owner of areas of the Wudinna Project.

· Alcrest Royalties Australia Pty Ltd retains a 1.5% NSR royalty over future mineral production from licenses EL6001, EL5953, EL6131, EL6317 and EL6489.

· A Native Title Agreement is in place with the Barngarla people.

· Aboriginal heritage surveys have been completed over EL5953, with no sites located in the immediate vicinity of aircore drilling

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.

· Paleochannel uranium exploration was undertaken by various parties in the 1980s and the 2010s around the Boland Prospect. Drilling was primarily rotary mud with downhole geophysical logging the primary interpretation method.

Geology

· Deposit type, geological setting and style of mineralisation.

· Target mineralisation is ionic rare earth mineralisation that occurs primarily within the Pidinga Formation within the Narlaby Palaeochannel, immediately above REE enriched Hiltaba Suite Granites

· Ionic REE mineralsiation also occurs in and adjacent to the Garford formation clays and silty sands.

· Significant chemical (pH & eH) differences exist between underlying saprolite and overlying Palaeochannel sediments. REEs are absorbed to reduced organics found within the Pidinga Formation

· Benchtop metallurgy studies indicate ISR amenability of rare earths within the Pidinga Formation basal sands summarized in RNS 1285Q (16 December 2024)

· Ionic REE mineralisation is confirmed through metallurgical desorption testing where high recoveries are achieved at benign acidities (pH4-3) at ambient temperature.

· QEMSCAN and petrology analysis support REE ionic mineralisation, with little to no secondary phases identified.

· Ionic REE mineralisation occurs in reduced clay intervals that contact both saprolite and permeable sand units. Mineralisation contains variable sand quantities that yield permeability and promote insitu recovery potential

· Mineralisation is located within a confined acquifer

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 being reported represent a small portion of the Boland target area. Coordinates for Wellfield drill holes are presented in Table 3.

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. Conversion factors tabulated below:

· The reporting of REE oxides is done so in accordance with industry standards with the following calculations applied:

· TREO = La2O3 + CeO2 + Pr6O11 + Nd2O3 + Sm2O3 + Eu2O3 + Gd2O3 + Tb4O7 + Dy2O3 + Ho2O3 + Er2O3 + Tm2O3 + Yb2O3 + Lu2O3 + Y2O3

· CREO = Nd2O3 + Eu2O3 + Tb4O7 + Dy2O3 + Y2O3

· LREO = La2O3 + CeO2 + Pr6O11 + Nd2O3

· HREO = Sm2O3 + Eu2O3 + Gd2O3 + Tb4O7 + Dy2O3 + Ho2O3 + Er2O3 + Tm2O3 + Yb2O3 + Lu2O3 + Y2O3

· MREO = Nd2O3 + Pr6O11 + Tb4O7 + Dy2O3

· NdPr = Nd2O3 + Pr6O11

· TREO-Ce = TREO - CeO2

· % Nd = Nd2O3/ TREO

· % Pr = Pr6O11/TREO

· % Dy = Dy2O3/TREO

· % HREO = HREO/TREO

· % LREO = LREO/TREO

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.

· Most intercepts are vertical and reflect true width intercepts.

· Follow-up sonic drilling is planned to delineate portions of the reported intersections that are recoverable and unrecoverable via ISR

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 and metallurgical testing

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.

· The metallurgical testing reported in this announcement represents the first phase of bench scale studies to test the extraction of ionic REEs via ISR processes.

· ISR study 1 was performed to achieve a pH 3 whilst ISR study 2 was performed at a pH of 2.

· Future metallurgical testing will focus on producing PLS under leach conditions to conduct downstream bench-scale studies for impurity removal and product precipitation.

· Hydrology, permeability and mineralogy studies are being performed on core samples.

· Installed wells are being used to capture hydrology base line data to support a future infield pilot study.

· Trace line tests shall be performed to emulate bench scale pore volumes.
