• Untested EM conductors located up-dip and down-plunge from MAD199 support potential for further significant mineralisation in this area

Above: fresh drill core from the massive sulphide interval of MAD199 between 342.12m to 343.4m which delivered average XRF readings of 7.34% Ni and 2.94% Cu (laboratory assays pending).

24/7 DIAMOND DRILLING CONTINUES:

• MAD200 in progress and planned to a depth of 600m to test a broad SQUID MLEM anomaly at West End, approximately 500m west of MAD199
• Three discrete and strong EM conductors were identified from the DHEM survey in MAD196 and are within the 200m strike of the SQUID MLEM anomaly, supporting the potential for the broad SQUID MLEM to represent a large conductive body at depth

DHEM SURVEYS IN PROGRESS:

• DHEM survey crew is at site and will complete a survey in MAD199
• Surveys will also be completed for MAD197 (West End) and MAD198 (Stricklands Deeps)
• MAD199 intersected the deepest high-grade mineralisation identified to date along the Cathedrals Belt and confirms the importance of DHEM surveys in searching for significant nickel-copper sulphides in the down-dip direction of the large intrusive system

Growth-focused Western Australian nickel company St George Mining Limited (ASX: SGQ) ("St George" or "the Company") is pleased to announce a new discovery of high-grade nickel-copper sulphides at its flagship Mt Alexander Project, located in the north-eastern Goldfields.

MAD199 was drilled to a downhole depth of 378.8m to test EM conductor MAD195_p1. The conductor is modelled with an EM plate having a length of 12m and depth extent of 45m, and very strong conductivity of 19,320 Siemens. A 10.96m interval of nickel-copper sulphides was intersected from 333.6m downhole, confirming the conductor as high-grade nickel-copper sulphides.

An additional two EM conductors are located proximal to MAD195_p1 and are also interpreted to have a massive sulphide source. MAD195_p2 is modelled with an EM plate having dimensions of 20m x 5m and conductivity of 22,950 Siemens. MAD195_p3 is modelled with an EM plate having dimensions of 9m x 6m and conductivity of 16,850 Siemens.

The combined strike length of these conductors suggests the presence of a significant volume of highgrade mineralisation in this location.

Significantly, the EM plate drilled by MAD199 has a depth extent of 45m in the down-dip direction of the intrusive host unit. This is very favourable for the potential continuity of the mineralisation at depth.

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

"We are delighted to have made another high-grade discovery with MAD199 and believe there is excellent potential to discover further high-grade mineralisation in other underexplored areas of the Cathedrals Belt.

"MAD199 has delivered an outstanding intersection of nickel-copper sulphides that may be indicating the presence of a large accumulation of mineralisation.

"At more than 300m below surface, this is the deepest massive nickel-copper sulphides identified in the Cathedrals Belt and confirms our interpretation that the large intrusive mineral system at the Cathedrals Belt can host significant mineralisation at depth.

"Importantly, there are multiple other EM conductors proximal to the MAD199 intersection – both up-dip and down-dip – which have yet to be tested. The result in MAD199 gives us great confidence that these additional conductors are also mineralisation and that we may have discovered a very fertile section of the Cathedrals intrusive unit.

"St George's diligent and systematic exploration efforts at Mt Alexander have already yielded four highgrade nickel-copper sulphide discoveries across a 5.5km strike length. The success with MAD199 extends the strike length and is enormously encouraging as we continue to prove up further nickel-copper mineralisation along the Cathedrals Belt.

"Mineralisation of the kind that we have at Mt Alexander is very rare – the combination of high-grade nickel, copper, cobalt and platinum group metals is simply not seen anywhere else in Western Australia, or Australia for that matter.

"We look forward to further results with downhole EM surveys in progress and drilling continuing 24/7."

MAD199 – A NEW DISCOVERY

The nickel-copper sulphides in MAD199 are preserved, suggesting they may be associated with a larger proximal body of mineralisation rather than having been remobilised from a very distant source.

Figure 1 shows the drill core tray for MAD199 with the interval from 339.6m to 345.5m. Coarse grained pentlandite and chalcopyrite are clearly evident in the massive sulphide core. Laboratory assays will confirm the grades of nickel and copper in the MAD199 interval as well as the values of cobalt and platinum group metals which are also typically present at high-grades in the Cathedrals Belt mineralisation.

Figure 1 - – drill core tray from MAD199 with the thick interval of nickel-copper sulphides.

A vector to more mineralisation:

Drilling to date has confirmed the nickel-copper sulphides discovered in the Cathedrals Belt are part of a large mineralised intrusive system. The intrusive host unit is known to extend for an east-west strike of more than 6.5km from Radar in the east to West End in the west, and to a depth of at least 600m below surface.

There is considerable scope to discover further mineralisation as the unit remains open to the east and west, as well as in the down-dip direction – particularly in the north-west part of the Belt where drilling is currently underway at West End.

The high-grade intersection in MAD199 is the deepest occurrence of massive nickel-copper sulphides drilled in the Belt and also the western most occurrence. The result in MAD199 is significant in confirming the prospectivity of unexplored and underexplored areas of the Cathedrals Belt for further high-grade mineralisation, particularly at depth and to the west:

At depth: Surface EM surveys have limited effectiveness beyond 250m/300m below surface, meaning any significant deposits below this level have yet to be identified. The thick mineralised intersection in MAD199 confirms this interpretation and supports the prospectivity for further significant mineralisation to be present in deeper parts of the intrusive unit.

The magnetotelluric/audio-magnetotelluric surveys completed at the Cathedrals Belt in 2020 indicated that the intrusive unit has a depth extent in some areas in excess of 1.5km, indicating a large intrusive system and deep magmatic structures that have the potential to host significant mineralisation below the penetration of surface EM surveys.

To the west: MAD197 was recently drilled at West End, approximately 500m to the west of MAD199 and in an area that has never been drilled. The hole intersected the intrusive unit, confirming the prospectivity of West End for nickel-copper sulphides. The success of MAD199 – as the western most occurrence of massive sulphides – further elevates the prospectivity for West End by confirming that the strike of high-grade mineralisation is open to the west.

MAD200 IN PROGRESS AT WEST END

The DHEM survey of MAD196 identified three strong off-hole conductors that are interpreted to have a massive sulphide source. The conductors are modelled with conductivity of 69,926 Siemens, 27,000 Siemens and 32,235 Siemens, respectively – conductivity that is notably higher than those EM conductors detected by MAD195.

The modelled plates for these EM conductors are relatively small but are situated within the southern portion of the large SQUID MLEM anomaly identified by a surface survey completed over the area in 2019. That survey identified a broad, single-component EM anomaly in this location; Figure 3.

The anomaly was identified in the late-time Channel 28 component BZ, which is known to have identified nickel-copper sulphides elsewhere at Investigators. The broad SQUID MLEM anomaly may represent an EM signal from one or more strong conductors down-dip of the current drilling and below the discrete conductors identified from MAD196.

The potential of this down-dip area to host significant mineralisation is being tested by MAD200, which is planned to a depth of 600m.

Figure 4 – map (against magnetic RTP 1VD data) showing drilling along the Cathedrals Belt and highlighting the most recently completed drill holes.

Based on the intersection angle of the drilling with the modelled intrusive unit, downhole widths noted are interpreted to be close to true widths.

Nickel and copper values shown above for recently completed drill holes are based on portable XRF analysis. They are preliminary in nature and a conclusive determination of the nickel, copper, cobalt and PGE values of the sulphide mineralisation will be confirmed when laboratory assays are available.

Average XRF readings in the massive sulphide interval are based on at least four readings per metre (unless otherwise stated) and are not length and density weighted. Metal content for intervals of disseminated sulphides are not accurately determined by portable XRF analysis and estimates for this style of mineralisation are based on geological logging.

COVID-19:

St George continues to manage its operations in compliance with COVID-19 regulations issued by State and Commonwealth authorities. We will continue to proactively manage drilling and other field programmes to protect the health and safety of our team and service providers.

Border restrictions in Western Australia and elsewhere have impacted on the movement of personnel for drill rig crews which has been constraining the availability of drill rigs. St George is in close contact with its drilling contractors to best manage access and continuity to drilling services.

RC Sampling: Samples are taken on a one metre basis and collectedusing uniquely numbered calico bags. The remaining material for thatmetre is collected and stored in a green plastic bag marked with thatspecific metre interval. The cyclone is cleaned with compressed airafter each plastic and calico sample bag is removed. If wet sample orclays are encountered then the cyclone is opened and cleanedmanually and with the aid of a compressed air gun. A blank sample isinserted at the beginning of each hole, and a duplicate sample istaken every 50th sample. A certified sample standard is also addedaccording to geology, but at no more than 1:50 samples.

	Aspects of the determination of mineralisationthat are Material to the Public Report.In cases where 'industry standard' work hasbeen done this would be relatively simple (eg'reverse circulation drilling was used to obtain 1m samples from which 3 kg was pulverised toproduce a 30 g charge for fire assay'). In othercases more explanation may be required, suchas where there is coarse gold that has inherentsampling problems. Unusual commodities ormineralisation types (eg submarine nodules)may warrant disclosure of detailed information.	RC Sampling: A 1m composite sample is taken from the bulk sampleof RC chips that may weigh in excess of 40 kg. Each sample collectedfor assay typically weighs 2‐3kg, and once dried, is prepared for thelaboratory as per the Diamond samples below.
		Diamond Core Sampling: Diamond core (both HQ and NQ2) is half‐core sampled to geological boundaries no more than 1.5m and no lessthan 10cm. Samples less than 3kg are crushed to 10mm, dried andthen pulverised to 75µm. Samples greater than 3kg are first crushedto 10mm then finely crushed to 3mm and input into the rotarysplitters to produce a consistent output weight for pulverisation.
		Pulverisation produces a 40g charge for fire assay. Elementsdetermined from fire assay are gold (Au), platinum (Pt) and palladium(Pd)witha1ppbdetectionlimit.TodetermineotherPGEconcentrations (Rh, Ru, Os, Ir) a 25g charge for nickel sulphide collectfire 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,Mo, Nb, Ni, P, Pb, S, Sb, Sn, Te, Ti, V, W, Zn. The sample is digestedwith nitric, hydrochloric, hydrofluoric and perchloric acids to effect asnear to total solubility of the sample as possible. The sample is thenanalysed using ICP‐AES or ICP‐MS.
		LOI (Loss on Ignition) will be completed on selected samples todetermine the percentage of volatiles released during heating ofsamples to 1000°C.
Drillingtechniques	Drill type (eg core,reverse circulation, open‐holehammer, rotary air blast, auger, Bangka, sonic,etc) and details (eg core diametre, triple orstandard tube, depth of diamond tails, face‐sampling bit or other type, whether core isoriented and if so, by what method, etc).	Diamond Core Sampling: The collars of the diamond holes weredrilled using RC drilling down through the regolith to the point ofrefusal or to a level considered geologically significant to change tocore. The hole was then continued using HQ diamond core until thedrillers determined that a change to NQ2 coring was required.
		The core is oriented and marked by the drillers. The core is orientedusing ACT Mk II electric core orientation.
		RC Sampling: The RC drilling uses a 140 mm diameter face hammertool. High capacity air compressors on the drill rig are used to ensurea continuously sealed and high‐pressure system during drilling tomaximise the recovery of the drill cuttings, and to ensure chipsremain dry to the maximum extent possible.
Drill samplerecovery	Method of recording and assessing core andchip sample recoveries and results assessed.	Diamond Core Sampling: Diamond core recoveries are recordedduring drilling and reconciled during the core processing andgeological logging. The core length recovered is measured for eachrun and recorded which is used to calculate core recovery as apercentage.
		RC Sampling: RC samples are visually checked for recovery, moistureand contamination. Geological logging is completed at site withrepresentative RC chips stored in chip trays.
	Measures taken to maximise sample recoveryand ensure representative nature of thesamples.	RC Sampling: Samples are collected using cone or riffle splitter.Geological logging of RC chipsis completed atsite with representativechips being stored in drill chip trays.
		Diamond Core Sampling: Measures taken to maximise core recoveryinclude using appropriate core diameter and shorter barrel lengththrough the weathered zone, which at Cathedrals and Investigators ismostly <20m and Stricklands <40m depth. Primary locations for coreloss in fresh rock are on geological contacts and structural zones, anddrill techniques are adjusted accordingly, and if possible, these zonesare predicted from the geological modelling.

The drill holes are drilled to intersect the modelled mineralised zonesat a near perpendicular orientation (unless otherwise stated).However, the orientation of key structures may be locally variableand any relationship to mineralisation has yet to be identified.
	If the relationship between the drillingorientation and the orientation of keymineralised structures is considered to haveintroduced a sampling bias, this should beassessed and reported if material.	No orientation based sampling bias has been identified in the datato date.
Samplesecurity	The measures taken to ensure sample security.	Chain of Custody is managed by the Company until samples pass to acertified assay laboratory for subsampling and assaying. The RCsample bags are stored on secure sites and delivered to the assaylaboratory by the Company or a competent agent. When in transit,they are kept in locked premises. Transport logs have been set up totrack the progress of samples.
Audits orreviews	The results of any audits or reviews of samplingtechniques and data.	Sampling techniques and procedures are regularly reviewedinternally, as is data. To date, no external audits have beencompleted on the drilling programme.

MineralTenement andLand Status	Type, name/reference number, location andownership including agreements or materialissues with third partiesincluding joint ventures,partnerships, overriding royalties, native titleinterests, historical sites, wilderness or nationalpark and environmental settings.	The Mt Alexander Project is comprised of six granted ExplorationLicences(E29/638,E29/548,E29/954,E29/962,E29/972andE29/1041). Tenement E29/638 is held in Joint Venture between StGeorge (75% interest) and Western Areas (25% interest). E29/638and E29/548 are also subject to a royalty in favour of a third partythat is outlined in the ASX Release dated 17 December 2015 (asregards E29/638) and the ASX release dated 18 September 2015 (asregards E29/548).
	The security of the tenure held at the time ofreporting along with any known impedimentstoobtaining a licence to operate in the area.	No environmentally sensitive sites have been identified on thetenements. A registered Heritage site known as Willsmore 1 (DAAidentification 3087) straddles tenements E29/548 and E29/638. Allfive tenements are in good standing with no known impediments.
ExplorationDone by OtherParties	Acknowledgment and appraisal of explorationby other parties.	Exploration on tenements E29/638 and E29/962 has been largelyfocused on the discovery of komatiite‐hosted nickel sulphides withinthe Mt Alexander Greenstone Belt. Exploration in the northernsection of E29/638 (Cathedrals Belt) and also limited exploration onE29/548 has been for mafic/ultramafic intrusion related Ni‐Cu‐PGEsulphides. No historic exploration has been identified on E29/954 orE29/972.
		Mafic‐Ultramafic intrusion related high grade nickel‐copper‐PGEsulphides were discovered at the Mt Alexander Project in 2008.Drilling was completed to test co‐incident electromagnetic (EM) andmagnetic anomalies associated with nickel‐PGE enriched gossans inthe northern section of current tenement E29/638. The drillingidentified high grade nickel‐copper mineralisation in granite‐hostedand East‐West orientated ultramafic units and the discovery wasnamed the Cathedrals Prospect.
Geology	Deposit type, geological setting and style ofmineralisation	The Mt Alexander Project is at the northern end of a westernbifurcation of the Mt Ida Greenstones. The greenstones are bound tothe west by the interpreted Ida Fault, a significant Craton‐scalestructure that marks the boundary between the Kalgoorlie Terrane(and Eastern Goldfields Superterrane) to the east and the YouanmiTerrane to the west.
		The Mt Alexander Project is prospective for further high‐gradekomatiite‐hosted nickel‐copper‐PGE mineralisation (both greenstoneand granite hosted) and also precious metal mineralisation (i.e.orogenic gold) that is typified elsewhere in the Yilgarn Craton.
Drill holeinformation	A summary of all information material to theunderstandingoftheexplorationresultsincludingtabulationofthefollowinginformation for all Material drill holes:• Easting and northing of the drill hole collar•Elevation or RL (Reduced Level – elevationabove 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 includedin the body of the relevant ASX releases.
Dataaggregationmethods	InreportingExplorationResults,weightingaveragingtechniques,maximumand/orminimum grade truncations (e.g. cutting of highgrades) and cut‐off grades are usually Materialand 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 matrixsulphide intersections the nominal lower cut‐off for nickel is 0.3%.

	Where aggregated intercepts incorporate shortlengths of high grade results and longer lengths	Any high‐grade sulphide intervals internal to broader zones ofsulphide mineralisation are reported as included intervals.
	of low grade results, the procedure used forsuchaggregation should be stated and some typicalexamples ofsuch aggregationsshould be shownin detail.	Any disseminated, matrix, brecciated or stringer sulphides with(usually) >1% nickel or copper on contact with massive sulphidemineralisation are grouped with the massive sulphides forcalculating significant intersections.
	The assumptions used for any reporting ofmetal equivalent values should be clearlystated.	No metal equivalent values are used for reporting explorationresults.
Relationshipbetweenmineralisationwidths andinterceptlengths	These relationships are particularly important inthe reporting of exploration results. If thegeometry of the mineralisation with respect tothe drill hole angle is known, its nature shouldbe reported. If it is not known and only the downhole lengths are reported, there should be aclear statement to this effect.	Assay intersections are reported as down hole lengths. Drill holes areplanned as perpendicular as possible to intersect the target EM platesand geological targets so downhole lengths are usually interpreted tobe near true width.
iagrams	Appropriate maps and sections(with scales) andtabulations of intercepts should be included forany significant discovery being reported. Theseshould include, but not be limited to a planeviewofdrillholecollarlocationsandappropriate sectional views.	A prospect location map, cross section and long section are shownin the body of relevant ASX Releases.
