COMPELLING NEW LITHIUM TARGETS AT MT ALEXANDER

HIGHLIGHTS

High-Priority Lithium Targets:

• Multiple new lithium drill targets identified at Mt Alexander – owned 100% by St George except for E29/638 (75% St George; 25% IGO) – following a project wide review of lithium prospectivity completed by ERM (formerly CSA Global)

• ERM is a prominent mining consultancy firm with industry leading credentials in hardrock lithium exploration

• The collection and analysis of the Potassium to Rubidium ratio (K:Rb) of feldspar crystals within numerous pegmatite outcrops at Mt Alexander has led to a breakthrough in the understanding of the lithium prospectivity and assisted in the prioritisation of lithium targets

• High-priority targets include an area proximal to the contact of the Copperfield Granite with the Mt Alexander greenstone belt – a favourable geological setting for potential lithium mineralisation and an analogue to the significant lithium discovery by Delta Lithium (ASX: DLI) at its nearby Mt Ida Project (14.6Mt @ 1.2% Li2O)[1] which is located less than 300m from the contact with the Copperfield Granite

• Drilling of the new lithium targets is scheduled for H2 2024

Emerging gold targets coincident with lithium:

• Additionally, four gold targets coincident with lithium targets were identified from the results of the recent soil surveys further supporting a geological analogue to the Mt Ida Project where high-grade gold is associated with the lithium deposits

• Exceptional assays of up to 4 g/t Au in rock chip and 180ppb in soil sampling

St George Mining Limited (ASX: SGQ ) (“ St George ” or “ the Company ”) is pleased to announce a big step forward in lithium targeting at its Mt Alexander Project in Western Australia.

John Prineas, St George Mining’s Executive Chairman said:

“Drilling at Mt Alexander has already confirmed the presence of high-grade lithium mineralisation – up to 1.8% Li2O – and very thick pegmatites up to 121m thick.

“The latest targeting work with external consultants at ERM has been focused on finding the most likely areas with potential for significant lithium mineralisation.

“The new gold targets are also compelling gold exploration opportunities in their own right – and made more exciting given the known correlation between lithium and gold occurrences at the neighbouring project of Delta Lithium.

“Four areas standout as priority targets across our large landholding. This is an exciting development in lithium targeting at Mt Alexander and we look forward to drilling these targets soon.”

NEW LITHIUM TARGETS FOR DRILLING

Mt Alexander hosts extensive pegmatite outcrop with more than 500 pegmatites mapped at the Project to date. Samples from many of these outcrops have recorded highly anomalous lithium values providing strong encouragement for the potential of significant lithium mineralisation at the Project.[2]

St George engaged external consultants at ERM (formerly CSA Global) to review the lithium potential at Mt Alexander and assist with definition of new drill targets.

Following a detailed review of drilling and other project data, St George and ERM personnel conducted a field assessment which included ground-truthing, lithological and structural mapping and geochemical analysis.

This field work included recording the potassium (K) and rubidium (Rb) values of feldspar within numerous outcropping pegmatites using a portable XRF analyser.

The K:Rb ratio provides a regional vector of fractionation occurring in pegmatite bodies. Generally, the lower the K:Rb ratio within feldspar, the more fractionated and prospective the pegmatite. A K:Rb ratio of less than 30 is considered to reflect potential for spodumene formation. This technique has proven very effective in prioritising specific areas of pegmatites at Mt Alexander for drilling.

323 samples were collected across the project area with K:Rb ratios ranging from more than 80 to less than 10. A clear trend from high K:Rb ratio to low K:Rb ratio can be seen trending from north to south at Mt Alexander, indicating several areas with potential for stronger lithium mineralisation (Figure 2).

Significantly, the K:Rb ratio results also support promising lithium soil anomalies seen in the recent soil survey where a number of priority targets were generated. For further details of the lithium soil anomalies, see our ASX Release dated 14 February 2024 Large Lithium Soil Anomalies at Mt Alexander.

The priority K:Rb ratio areas are proximal to the Jailbreak Prospect where drilling intersected grades up to 1.8% Li2O. Several new target areas identified by ERM and by soil sampling have not been drill tested to date.

COINCIDENT GOLD ANOMALISM

The recent Mt Alexander soil surveys have now also been assessed for all commodities including gold. Results have shown several prominent gold anomalies coincident with lithium anomalies.

This is considered a common occurrence across Western Australia for high-grade lithium mineralisation with numerous lithium discoveries alongside historic gold projects – including Delta Lithium’s Mt Ida Project 15km south of Mt Alexander. It appears that lithium and gold occurrences can utilise the same structures and depositional settings.

A maximum value of 180 ppb Au was reported from 1077 total samples taken at Mt Alexander. This is considered highly anomalous when combined with the presence of several pathfinder elements including As, Ag, Bi, Co, Cu, Ni, Te and W. Importantly, several anomalous gold values are coincident with major structures – this is a compelling geological setting for potential gold mineralisation (Figure 1).

These gold anomalies provide additional high order targets and have been prioritised for the next Mt Alexander drill programme.

HIGH-PRIORITY TARGETS

After incorporating results from the latest targeting studies, the high-priority target areas with lithium in soils, gold in soils and low K:Rb ratio are:

Priority 1 : Jailbreak West which recorded consistently very low (<10) K:Rb ratios and a large soil anomaly, indicating strong likelihood for highly fractionated pegmatites with potential for spodumene formation. Within the same structural corridor as Jailbreak with strong coincident gold anomalism. No previous drilling

Priority 2 : The area has several large stacked pegmatite outcrops (up to 15m wide) and indications of high fractionation using the K:Rb. Within a structural setting analogous to Mt Ida and a strong coincident gold anomaly. No previous drilling

Priority 3 : East of Jailbreak and near the Copperfield greenstone contact – interpreted to be a direct exploration analogue to the Mt Ida discoveries of Delta Lithium. Minimal drilling that is to be extended given new information from latest mapping exercise.

Priority 4 : An area south of Jailbreak and bordering the Mt Bevan Project currently being explored by Hancock Prospecting Pty Ltd. Large soil anomaly with minimal outcrop but in the same geological setting to Jailbreak. Potential for lithium mineralisation below the shallow cover. No previous drilling.

NOTE:

Visual observations of pegmatites are based on geological logging and visual interpretations and should not be considered a substitute for laboratory analysis which is required to determine the concentration of any elements that may be indicative of possible mineralisation associated with pegmatites that are mapped, sampled from rock chips or intersected by drilling.

XRF values of pegmatite samples are based on spot readings only. The readings are used for preliminary geochemical interpretation only and considered appropriate for this method of exploration targeting. A conclusive determination of the metal content of a pegmatite sample can only be determined following laboratory analysis.

About the Mt Alexander Project:

The Mt Alexander Project is located 120km south-west of the Agnew-Wiluna Belt, in a region which hosts numerous world-class lithium, nickel and gold deposits. The Project comprises eight tenements – seven granted exploration licences, E29/638, E29/548, E29/962, E29/954, E29/972, E29/1041 and E29/1143 and one Prospecting Licence P29/2680 – which are a contiguous package. An additional exploration licence – E29/1093 – is located to the southeast of the core tenement package.

The Cathedrals, Stricklands, Investigators and Radar nickel-copper-cobalt-PGE discoveries are located on E29/638, which is held in joint venture by St George (75%) and IGO Limited (25%). St George is the Manager of the Project, with IGO retaining a 25% non-contributing interest (in E29/638 only) until there is a decision to mine.

The following section is provided for compliance with requirements for the reporting of exploration results under the JORC Code, 2012 Edition.

Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections)

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. Rock Chip: a sample is collected from in-situ material at surface adjudged by the geologist on site. The sample between 0.5-2kg is collected in a marked calico bag for submission for assay. K:Rb sample: a feldspar sample is collected from in-situ material at surface pegmatite adjudged by the geologist on site. The Sample is less than 0.2kg. It is marked and placed in a pre-marked calico for analysis. Soils: Each soil sample is taken from a manually excavated pit approximately 300mm deep (depending on the nature of the sampling medium). The loose material at the bottom of the pit is placed through a series of sieves, with the fine fraction of the 180micron sieve placed into pre-numbered paper geochemical sample envelope. The sample envelopes are then sent to a certified laboratory for assay.
	Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. Rock Chips: Samples are collected by hand or dislodged by geo pick of in-situ material at surface. Soils: Each sample is sourced from the loose material at the bottom of the sample pit which is considered to be representative of the profile being targeted.
	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. Rock Chips: samples are taken under the discretion of geologists with the intention of taking a representative rock chip sample for the parent rock sampled. K:Rb sample: are taken under the discretion of geologists from suitable outcropping pegmatites. Only samples adjudged felspars by the geologist are collected. Soils: A single sample are taken on a predetermined spacing and collected using uniquely numbered calico bags. Each sample collected for assay typically weighs 50g, and once dried, is prepared for the laboratory. Pulverisation further reduces the particle size with 90% of the material passing 75micron. The sample is then assayed using the peroxide fusion method.
Drilling techniques	Drill type (eg core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (eg core diametre, 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). Not applicable as drilling results are not reported.
Drill sample recovery	Method of recording and assessing core and chip sample recoveries and results assessed. Not applicable as drilling results are not reported.

1

Criteria	JORC Code explanation Commentary
	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. To date, no sample recovery issues have yet been identified that would impact on potential sample bias in the soil profile or sampling methods.
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. Each sample is recorded for the lithology, type and nature of the soil. The surface topography and type is recorded at the sample location.
	Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography. The logging is both qualitive and quantitive in nature, with sample recovery and volume being recorded,
	The total length and percentage of the relevant intersections logged. Not applicable as drilling results are not reported.
Sub-sampling techniques and sample preparation	If core, whether cut or sawn and whether quarter, half or all core taken. Not applicable as drilling results are not reported.
	If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. All samples were dry when sampled where with regard to soils sampling.
	For all sample types, the nature, quality and appropriateness of the sample preparation technique. Samples are dried, crushed and pulverized to produce a homogenous representative sub-sample for analysis at the laboratory.
	Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples. QAQC analysis are routinely completed during pXRF analysis. The instrument is calibrated on a daily basis and measured against standard to check accuracy at a minimum 1:50 readings. No QAQC are inserted within the submitted samples and are not deemed necessary for this stage of exploration. Internal laboratory QAQC measures are considered sufficient
	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. Rock chips: representivity and suitability of each sample is adjudged by the onsite geologist. The company is not aware of any bias within the sampling of rock chips at the project to date. K:Rb sample: bias is removed from the sampling technique as only the feldspar minerals are collected for analysis. The sample material is sourced from the bottom of the pits with efforts made to reduce the amount of surficial ‘float’ material entering the sample. Sieving of the sample helps to homogenise and reduce size fraction of the sample
	Whether sample sizes are appropriate to the grain size of the material being sampled. The sample sizes are considered to be appropriate to screen for the geochemical signatures of K:Rb ratio analysis using pXRF. and associated geology. The sample sizes are considered to be appropriate to screen for the geochemical signatures for multi-element analysis

2

Criteria	JORC Code explanation Commentary
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. The soil samples are analysed using an Peroxide Fusion Digest. Rock Chip samples have been analysed for Al, Ca, Fe, K, Li, Mg, Mn, P, S, Si, Ti, V, Cs, Nb, Ta, Ga, Sn, Be, Mo, Rb have been determined by either Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) or Inductively Coupled Plasma Mass-Spectrometry (ICP- MS) Au, Pt and Pd have been determined by Fire assay. The assay method and detection limits are appropriate for analysis of the elements required. K:Rb ratios are determined using a pXRF instrument for each sample collected. Due to the homogeneous nature of the sampling medium (Feldspar mineral) the pXRF is deemed suitable for determining readings of both target elements. The results have been found to be both reliable and repeatable through the survey thus far.
	For geophysical tools, spectrometres, handheld XRF instruments, etc, the parametres used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. A handheld XRF instrument (Olympus Innov-X Spectrum Analyser) is used to provide an initial assay of the geochemical sample onsite. One reading is taken per sample. The instruments are serviced and calibrated at least once a year. Field calibration of the XRF instrument using standards is periodically performed (usually daily). The handheld XRF results are only used for preliminary assessment of the soils and rock chip samples element compositions, prior to the receipt of assay results from the certified laboratory.
	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. Laboratory QAQC involves the use of internal lab standards using certified reference material (CRMs), blanks and pulp duplicates as part of in-house procedures. The Company also submits a suite of CRMs, blanks and selects appropriate samples for duplicates. Sample preparation checks for fineness are performed by the laboratory to ensure the grind size of 90% passing 75µm is being attained.

	The use of twinned holes. Not applicable as drilling results are not reported.
	Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Primary data is captured onto a tablet using GIS software and includes geological logging, sample data and QA/QC information. This data, together with the assay data, is entered into the St George Mining central SQL database which is managed by external consultants.
	Discuss any adjustment to assay data. No adjustments or calibrations will be made to any primary assay data collected for the purpose of reporting assay grades and mineralised intervals. For the geological analysis, standards and recognised factors may be used to calculate the oxide from assayed elements, or to calculate volatile free mineral levels in rocks.
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. The sample locations are determined by using a handheld GPS system with an expected accuracy of +/-5m for easting, northing and elevation. This is considered adequate for the type and purpose of the surveys.
	Specification of the grid system used. The grid system used is GDA94, MGA Zone 51.
	Quality and adequacy of topographic control. Elevation data has been acquired using DGPS surveying at specific location across the project, including drill collars, and entered into the central database. A topographic surface has been created using

	this elevation data. The local elevation data is also captured with the handheld GPS when sampling.
Data spacing and distribution	Data spacing for reporting of Exploration Results. The soil samples were taken at 100m intervals along the geochemical survey lines 200m apart. Rock chip and K:Rb samples are taken where suitable.
	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. Not applicable as drilling results are not reported.
	Whether sample compositing has been applied. No compositing has been applied to the exploration results.
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. Rock Chips/K:Rb samples: The samples are taken at the discretion of the geologist on site. However, the orientation of key structures may be noted whilst mapping exercises are undertaken. The soil samples are taken at regular intervals, at a near perpendicular orientation (unless otherwise stated). However, the orientation of key structures may be locally variable and any relationship to potential mineralisation has yet to be identified.
	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. No orientation based sampling bias has been identified in the data to date.
Sample security	The measures taken to ensure sample security. Chain of Custody is managed by the Company until samples pass to a duly certified assay laboratory for subsampling and assaying. The sample bags are stored on secure sites and delivered to the assay laboratory by the Company or a competent agent. When in transit, they are kept in locked premises. Transport logs have been set up to track the progress of samples. The chain of custody passes upon delivery of the samples to the assay laboratory.
Audits or reviews	The results of any audits or reviews of sampling techniques and data. Sampling techniques and procedures are regularly reviewed internally, as is the data. The soils programme has been reviewed by third parties and consultant geologists.

Exploration Done by Other Parties	Acknowledgment and appraisal of exploration by other parties. Exploration on tenements E29/638 and E29/962 has been largely for komatiite-hosted nickel sulphides and pegmatite hosted lithium caesium tantalum deposits in the Mt Alexander Greenstone Belt. Exploration in the northern section of E29/638 (Cathedrals Belt) and also limited exploration on E29/548 has been for intrusive Ni-Cu sulphides in granite terrane. No historic exploration has been identified on E29/954 or E29/972. Mafic-Ultramafic intrusion related high grade nickel-copper-PGE sulphides were discovered at the Mt Alexander Project in 2008. Drilling was completed to test co-incident electromagnetic (EM) and magnetic anomalies associated with nickel-PGE enriched gossans in the northern section of current tenement E29/638. The drilling identified high grade nickel-copper mineralisation in granite-hosted and East-West orientated ultramafic units and the discovery was named the Cathedrals Prospect.
Geology	Deposit type, geological setting and style of mineralisation The Mt Alexander Project is at the northern end of a western bifurcation of the Mt Ida Greenstones. The greenstones are bound to the west by the interpreted Ida Fault, a significant Craton-scale structure that marks the boundary between the Kalgoorlie Terrane (and Eastern Goldfields Superterrane) to the east and the Youanmi Terrane to the west. The Mt Alexander Project is prospective for further high-grade nickel- mineralisation (both komatiite and mafic-ultramafic intrusive hosted), lithium mineralisation and also precious metal mineralisation (i.e. orogenic gold) that is typified elsewhere in the Yilgarn Craton.
Drill hole information	A summary of all information material to the understanding of the exploration results including tabulation of the following information for all Material drill holes: • Easting and northing of the drill hole collar •Elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar • Dip and azimuth of the hole • Down hole length and interception depth • Hole length Drill hole collar locations are shown in the maps and tables included in the body of the relevant ASX releases.
Data aggregation methods	In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually Material and should be stated. Reported assay intersections are length and density weighted. Significant intersections are determined using both qualitative (i.e. geological logging) and quantitative (i.e. lower cut-off) methods. For massive sulphide intersections, the nominal lower cut-off is 2% for either nickel or copper. For disseminated, blebby and matrix sulphide intersections the nominal lower cut-off for nickel is 0.3%.
	Where aggregated 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. Any high-grade intervals internal to broader zones of mineralisation are reported as included intervals.
	The assumptions used for any reporting of metal equivalent values should be clearly stated. No metal equivalent values are used for reporting exploration results.
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 Assay intersections are reported as down hole lengths. Drill holes are planned as perpendicular as possible to intersect the target EM plates and geological targets so downhole lengths are usually interpreted to be near true width.
