ENCOURAGING LITHIUM RESULTS EXPAND TARGETS AT MT ALEXANDER

HIGHLIGHTS

+120m thick pegmatite at Manta supports wider lithium potential:

  • Assays for MAD213, which was drilled at the Manta Prospect on E29/638 (75% St George; 25% IGO) and intersected a wide zone with multiple pegmatites – including a continuous 120.8m interval – indicate local fractionation of the pegmatites that may represent the distal part of a zoned lithium-bearing system

  • Major structures are interpreted to be associated with the thick flat-lying pegmatites hosted in granite, supporting the potential for the pegmatites to extend into a more favourable host in the greenstone belt, adjacent and intruded by the granite source

  • The thick flat-lying pegmatite at Manta is modelled by seismic data as a strong, 1,000m diameter circular feature, with additional geophysics and drilling planned to test the wider potential for lithium bearing pegmatites around Manta

Extensive mineralised pegmatite field at Jailbreak, open along strike and at depth:

  • Further assay results from the recent 2023 drilling programme at the Jailbreak Prospect confirm multiple lithium-bearing pegmatites with a peak value of 1.28% Li2O

  • Lithium-bearing pegmatites now identified by drilling across a 2km strike of the pegmatite corridor with a further 13km-long part of the corridor that hosts an extensive network of mapped pegmatites yet to be tested by drilling

  • Drilling at Jailbreak has intersected multiple pegmatites that have potential to become thicker at depth, similar to results reported by other explorers in the region[1]

St George Mining Limited (ASX: SGQ ) (“ St George ” or “ the Company ”) is pleased to report further encouraging lithium exploration results at its Mt Alexander Project in Western Australia.

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

“Our understanding of the lithium prospectivity continues to grow at Mt Alexander with recent drill results confirming high-grade and anomalous lithium across a wide area.

“Most encouraging is the very thick 120.8m, flat-lying and locally fractionated zone of pegmatites intersected in hole MAD213 at the Manta Prospect, approximately 9km north of the Jailbreak Lithium Prospect.

“These types of pegmatites are what is required for large mineral deposits and we will continue to test for potential extensions of the Manta pegmatites within and below the adjacent greenstone belt.

“We have only just begun to realise the wider lithium potential at Mt Alexander with the latest drilling confirming the presence of major structures that can produce wide extensional openings for thick fractionated pegmatites to intrude.

“The results for MAD213 confirm that large-scale pegmatite intrusions have occurred and that they are showing signs of prospectivity for lithium. It is now down to identifying the more fractionated lithium-caesium-tantalum (LCT) zone within the pegmatite hosted mineral system.

“We are also encouraged by recent excellent results announced by Delta Lithium at its nearby Mt Ida Project and the confirmation by Hancock Prospecting[2] that it will proceed with a lithium exploration joint venture for Mt Bevan which has ground that wraps around our Mt Alexander tenure.”

EARLY INDICATIONS OF LARGE-SCALE PEGMATITE INTRUSION MODEL

MAD213 intersected a 120.8m continuous interval of pegmatite which occurs within a 225m zone comprising multiple pegmatites (the Manta pegmatite zone ); refer to St George ASX Release dated 29 March 2023 120 Metre Pegmatite Intersection at Mt Alexander.

Assays from the pegmatites intersected in MAD213 have provided indications of a wide, multi-phase and locally fractionated pegmatite system which has potential to host lithium mineralisation where the pegmatites are intruded into more prospective host lithologies within the adjacent greenstone sequence at Mt Alexander.

The K:Rb (potassium to rubidium) ratio derived from the assays for MAD213 highlights the prospectivity of the Manta pegmatite zone. The ratio is an indicator of a fractionated pegmatite, where the pegmatite melt has evolved as it moves further form its source granite. A K:Rb ratio of less than 150 is a favourable indicator of fractionated pegmatites. The lower the K:Rb ratio, the more fractionated and prospective the pegmatites are interpreted to be.

A favourable K:Rb ratio associated with a Nb:Ta (niobium to tantalum) ratio of less than 5 is a further indication of fractionated pegmatites. A summary of the key geochemical results for MAD213 showing both ratios is included below in Table 1.

The current interpreta�on of the reflector is constrained by the extent of the ini�al survey. Further geophysics and drilling are planned to iden�fy the full extent of the Manta pegma�tes and assist in defining where lithium frac�ona�on may occur.

regional-scale structure. Major structures can create wide extensional/dila�onal openings for pegma�tes to intrude and enable frac�ona�on to occur to form large volume lithium deposits. The excep�onal thickness of the Manta pegma�tes and the associa�on with an interpreted regional-scale structure shows some important similari�es with other major lithium deposits in Western Australia.

LCT pegma�tes have already been intersected at Mt Alexander (see our ASX Release dated 29 May 2023 Mt Alexander Exploration Update ), giving further support for the poten�al of the thick pegma�tes intersected at Manta represen�ng a distal part of a larger lithium mineral system.

MINERALISED PEGMATITES IDENTIFIED OVER A WIDE AREA AT JAILBREAK

Further assay results have been received for the 2023 drill programme which con�nue to demonstrate the presence of lithium mineralised pegma�tes that commence from or near surface and con�nue to depths of up to 300m below surface. High grades – up to 1.28% Li2O – have been returned in the latest assays, highligh�ng the poten�al of the pegma�te system.

The latest assay results received are shown in Table 2. Together with the assay results reported in our ASX Release dated 29 May 2023 Mt Alexander Exploration Update , these include all the significant and anomalous assay results from the 2023 drilling completed to date. The results have con�nued to build our understanding of the geology and wider poten�al of the lithium-bearing pegma�te system.

2O results, many coincident with anomalous caesium, rubidium and locally tantalum and �n results.

The widespread presence of anomalous lithium at Jailbreak is indica�ve of this area being part of a frac�onated pegma�te system with poten�al for stronger mineralisa�on along strike and down dip from current drilling. As other recent drilling in the region has shown[3] , thick mineralised parts of the system commonly occur at depths of +200m below surface. There is only very limited drilling at this depth so far at Mt Alexander.

sequence – an area that lies within the 15km-long pegma�te corridor adjacent to the Copperfield Granite, the interpreted source of the mineralised pegma�tes at the Mt Ida Project of Delta Lithium.

Only 2km of this 15km-long corridor within St George’s tenements has been tested by drilling to date. The southern extension of the corridor, towards the Mt Bevan Project of the Hancock, Hawthorn and Legacy joint venture, con�nues for at least another 1.5km and will be a priority focus of further drilling.

In addi�on, the northern extension of the corridor – that includes the recently acquired 100% owned E29/1143 (the bulk of which lies some 6km to the north of Jailbreak) – will be tested by drilling for the first �me. The extensive network of pegma�tes mapped in these areas have yet to be drilled, highligh�ng the explora�on upside of the area.

BASE METALS INTERCEPTED AT JAILBREAK

Assays for MARD247, which was targe�ng the down-dip extension of the J1 pegma�te at Jailbreak, indicate that – in addi�on to lithium – high-grade zinc was intersected towards the end of that hole.

The stringer sulphide mineralisa�on was observed in quartz veining associated with extensive altera�on halos within a wide zone of sheared mafic host rocks. Highlights include:

  • 1.6m @ 3.4% Zn, 0.13% Cu, 0.1% Pb and 3.0 g/t Ag from 485.4m o including 0.45m @ 10.6% Zn, 0.4% Cu, 0.33% Pb and 10.3g/t Ag from 486.55m

High-grade zinc mineralisa�on coupled with elevated copper, lead and silver is typical of certain base metal deposits including VMS-style deposits. No targeted explora�on has ever occurred for this style of deposit at Mt Alexander. The occurrence of high-grade base metal mineralisa�on in MAD247 is significant from an explora�on perspec�ve and warrants further inves�ga�on of the source.

About the Mt Alexander Project:

The Mt Alexander Project is located 120km south-west of the Agnew-Wiluna Belt, which hosts numerous world-class nickel deposits. The Project comprises seven granted exploration licences – E29/638, E29/548, E29/962, E29/954, E29/972, E29/1041 and E29/1143 – which are a contiguous package. An additional two exploration licences – E29/1093 and E29/1126 – are 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 Jailbreak Lithium Prospect is on E29/268 and E29/962. With the exception of E29/638, all Project tenements are owned 100% by St George.

_Diamond Core Sampling:_The sections of the core that are selected
for assaying are marked up and then recorded on a sample sheet for
cutting and sampling at the certified assay laboratory. Samples of HQ

after each plastic and calico sample bag is removed. If wet sample or
clays are encountered then the cyclone is opened and cleaned
manually and with the aid of a compressed air gun. A blank sample is
inserted at the beginning of each hole, and a duplicate sample is
taken every 50thsample. A certified sample standard is also added
according to geology, but at no more than 1:50 samples.
Geological logging of RC chips is completed at site with
representative chips being stored in drill chip trays. Downhole
surveys of dip and azimuth are conducted using a single shot camera
every 30m, and using a downhole Gyro when required, to detect
deviations of the hole from the planned dip and azimuth. The drill-
hole collar locations are recorded using a hand-held GPS, which has
an accuracy of +/- 5m. All drill-hole collars will be surveyed to a
greater degree of accuracy using a certified surveyor at a later date.
_Diamond Core Sampling:_For diamond core samples, certified sample
standards were added as every 50thsample. Core recovery
calculations are made through a reconciliation of the actual core and
the driller’s records. Downhole surveys of dip and azimuth were
conducted using a single shot camera every 30m to detect deviations
of the hole from the planned dip and azimuth. The drill-hole collar
locations are recorded using a hand-held GPS, which has an accuracy
of +/- 5m.

Elements for allbase metalssuites go through the following two
analytical methods:
Pulverisation produces a 40g charge for fire assay. Elements
determined from fire assay are gold (Au), platinum (Pt) and palladium
(Pd) with a 1ppb detection limit. To determine other PGE
concentrations (Rh, Ru, Os, Ir) a 25g charge for nickel sulphide collect
fire assay is used with a 1ppb detection limit.
Other elements will be analysed using an acid digest and an ICP finish.
These elements are: Ag, Al, As, Bi, Ca, Cd, Co, Cr, Fe, K, Li, Mg, Mn,

techniques are adjusted accordingly, and if possible, these zones are
predicted from the geological modelling.
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.
Logging of samples records lithology, mineralogy, mineralisation,
structures (core only), weathering, colour and other noticeable
features. Chips and core was photographed in both dry and wet
form.
Whether logging is qualitative or quantitative in
nature. Core (or costean, channel, etc)
photography.
The logging is both qualitive and quantitative in nature, with sample
recovery and volume being recorded,
The total length and percentage of the relevant
intersections logged.
All drill holes are geologically logged in full and detailed litho-
geochemical information is collected by the field XRF unit. The data
relating to the elements analysed is used to determine further
information regarding the detailed rock composition.
Sub-sampling
techniques and
sample
preparation
If core, whether cut or sawn and whether
quarter, half or all core taken.
_Diamond Core Sampling:_Diamond core was drilled with HQ and NQ2
size and sampled as complete half core to produce a bulk sample for
analysis. Intervals selected varied from 0.3 – 1m (maximum) The HQ
and NQ2 core is cut in half length ways just to the right of the
orientation line where available using a diamond core saw. All
samples are collected from the same side of the core where
practicable.
Assay preparation procedures ensure the entire sample is pulverised
to 75 microns before the sub-sample is taken. This removes the
potential for the significant sub-sampling bias that can be introduced
at this stage.
If non-core, whether riffled, tube sampled,
rotary split, etc and whether sampled wet or
dry.
RC samples are collected in dry form. Samples are collected using
cone or riffle splitter when available. Geological logging of RC chips is
completed at site with representative chips being stored in drill chip
trays.
For all sample types, the nature, quality and
appropriateness of the sample preparation
technique.
RC Sampling: Sample preparation for RC chips follows a standard
protocol.
The entire sample is pulverised to 75µm using LM5 pulverising mills.
Samples are dried, crushed and pulverized to produce a homogenous
representative sub-sample for analysis. A grind quality target of 90%
passing 75µm is used.

Quality control procedures adopted for all sub-
sampling stages to maximise representivity of
samples.
Quality control procedures include submission of Certified Reference
Materials (standards), duplicates and blanks with each sample batch.
QAQC results are routinely reviewed to identify and resolve any
issues_.
_RC Sampling:
Field QC procedures maximise representivity of RC
samples and involve the use of certified reference material as assay
standards, along with blanks, duplicates and barren washes.
_Diamond Core Sampling:_Drill core is cut in half lengthways and the
total half-core submitted as the sample. This meets industry
standards where 50% of the total sample taken from the diamond
core is submitted.
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.
Duplicate samples are selected during sampling. Samples comprise
two quarter core samples for Diamond Core. Duplicate RC samples
are captured using two separate sampling apertures on the splitter.
Whether sample sizes are appropriate to the
grain size of the material being sampled.
The sample sizes are considered to be appropriate to correctly
represent base metal sulphide mineralisation and associated geology
based on: the style of mineralisation (massive and disseminated
sulphides), the thickness and consistency of the intersections and the
sampling methodology.
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 assay method and detection limits are appropriate for analysis of
the elements required.
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
and not for reporting of 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.
Verification of
sampling and
assaying
The verification of significant intersections by
either independent or alternative company
personnel.
Significant intersections and assays are verified by the Company’s
Technical Director and Consulting Field Geologist.
The use of twinned holes.
No twinned holes have been planned for the current drill
programme.
Documentation of primary data, data entry
procedures, data verification, data storage
(physical and electronic) protocols.
Primary data is captured onto a laptop using acQuire 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

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 handheld GPS 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.
Data spacing
and
distribution
Data spacing for reporting of Exploration
Results.
The spacing and distribution of holes is not relevant to the drilling
programs which are at the exploration stage rather than definition
drilling.
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.
The completed drilling at the Project is not sufficient to establish the
degree of geological and grade continuity to support the definition of
Mineral Resource and Reserves and the classifications applied under
the 2012 JORC code.
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.
The drill holes are drilled to intersect the modelled mineralised zones
at a near perpendicular orientation (unless otherwise stated).
However, the orientation of key structures may be locally variable
and any relationship to 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.

Parties 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 komatiite-hosted 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 The Mt Alexander Project is at the northern end of a western
mineralisation 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)
and also precious metal mineralisation (i.e. orogenic gold) that is
typified elsewhere in the Yilgarn Craton.
MT Alexander is also prospective for pegmatite hosted Lithium
mineralisaion. The Mt Ida region is a growing Lithium district within
the Northern Goldfields area.

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.
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 sulphide 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
hole lengths are reported, there should be a
clear statement to this effect.
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.
iagrams 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 plane
view of drill hole collar locations and
appropriate sectional views.
A prospect location map, cross section and long section are shown
in the body of relevant ASX Releases.

representative reporting of both low and high
grades and/or widths should be practiced to
avoid misleading reporting of Exploration

Reports on recent exploration can be found in ASX Releases that are
available on our website at www.stgm.com.au:
The exploration results reported are representative of the
mineralisation style with grades and/or widths reported in a
consistent manner.
