NEW EM CONDUCTORS SUPPORT GROWTH POTENTIAL AT HIGH-GRADE MT ALEXANDER NICKEL-COPPER SULPHIDE PROJECT

NEW NICKEL-COPPER SULPHIDE TARGETS IDENTIFIED AT WEST END:

• Multiple off-hole electromagnetic (EM) conductorsidentified by the downhole EM (DHEM) survey in MAD200
• One of the three new EM conductors is modelled as a large EM plate located over 75m to the north-west of MAD200 within the interpreted down-dip extension of the intrusive unit that is known to host massive nickel-copper sulphides in other parts of the Cathedrals Belt
• A further three very strong EM conductors are located in this area, identified from the DHEM survey in the nearby MAD196, supporting the potential for significant nickel-copper sulphides in this underexplored part of the West End Prospect

SEISMIC SURVEY SCHEDULED TO COMMENCE NEXT WEEK:

• Seismic survey over the western section of the Cathedrals Belt is planned to commence next week, and will cover the area at West End where the new EM conductors have been identified
• Survey will assist in guiding future deeper drilling through high-definition mapping of structures and potential mineralisation to depths up to 2km from surface

SCOPING STUDY FOR STRICKLANDS STARTER MINE:

• Ore-sorting process being trialled with the aim of upgrading the non-massive sulphide ore prior to processing
• New glycine leaching technology developed by Western Australia's Curtin University is due to be trialled for processing of nickel-copper sulphides
• The glycine-based process uses a non-toxic, biodegradeable reagent with zero carbon emissions and is a potential alternative processing method to conventional flotation circuits
• Metallurgical test work in Canada is continuing

Growth-focused Western Australian nickel company St George Mining Limited (ASX: SGQ) ("St George" or "the Company") is pleased to provide an update on exploration and development activities at its flagship Mt Alexander Project, located in the north-eastern Goldfields.

NEW EM TARGETS FOR MASSIVE NICKEL-COPPER SULPHIDES

The DHEM survey in MAD200 has identified three off-hole EM conductors, ranging in strike length from 250m, 60m and 40m respectively.

MAD200 intersected a 12.7m intrusive unit from 500.7m downhole including approximately 1.4m of disseminated and blebby nickel-copper sulphides from 512m downhole (<5% sulphides with pentlandite (pn), chalcopyrite (cp) and pyrrhotite (py)) with laboratory assays pending.

These nickel-copper sulphides are located on the basal contact and are preserved. This is a textbook geological setting supporting the potential for further nickel-copper sulphide deposits proximal to MAD200.

The new EM anomalies identified in MAD200 are of weak to moderate conductance (<1,000s). The largest of the EM plates is located 75m to the north-west of MAD200, being the detection limit of the DHEM system, and therefore may represent a vector to stronger, more distant mineralisation.

Figure 1 – Recent drilling and DHEM anomalies overlaying MMR (MMC) Image and magnetics (RTPFVD)

Significantly, a number of low conductivity EM anomalies have been drilled along the Cathedrals Belt and confirmed as nickel-copper sulphides including:

• MAD201 drilled a target modelled with less than 1,000 Siemens and returned a 2.4m thick nickelcopper sulphide intercept (laboratory assays are pending)
• MAD38 drilled a target modelled with 1,300 Siemens and confirmed high-grade nickel-copper sulphides with assays of:
  • 2.74m @ 3.77% Ni, 1.48% Cu, 0.10% Co, 3.85g/t total PGEs, 0.17g/t Au and 5.49g/t Ag from 25.4m including
  • 0.54m @ 8.59% Ni, 3.43% Cu, 0.24% Co, 6.73g/t total PGEs, 0.14g/t Au and 10g/t Ag from 27.6m

The successful intersection of nickel-copper sulphides at these previous targets indicates that weak conductors can be a vector to high-grade sulphide mineralisation. The low conductivity reading for these and the MAD200 EM anomalies may be because the target is on the edge of the range of detectability – typically 50m to 75m around a drill hole in a DHEM survey.

The DHEM survey in MAD196, which tested 50m up-dip from MAD200, identified three very strong EM conductors that remain untested by drilling. These conductors are modelled with conductivity of 69,926 Siemens, 27,000 Siemens and 32,235 Siemens, respectively, and are interpreted to have a massive sulphide source. For further details of these conductors, see our ASX Release dated 7 April 2021 Update – Mt Alexander Nickel-Copper Sulphide Project.

The presence of multiple conductors proximal to MAD200 and MAD196 is further support for the potential of significant sulphide mineralisation in this underexplored area of West End.

SEISMIC SURVEY:

The seismic survey across the western part of the Cathedrals Belt is scheduled to commence next week. The survey is designed to map the host intrusive structures to a depth up to 2km and may also be able to identify accumulations of sulphide mineralisation within these structures.

The survey will cover the West End area and results will assist in designing further deeper drilling to test the multiple EM conductors identified in this area; see Figure 2.

Figure 2 – map (against magnetic RTP 1VD data) showing survey lines for the deep ground penetrating radar (DGPR) and seismic surveys as well as areas of known nickel-copper sulphides. The DGPR survey at the Cathedrals Belt has been completed with processing of results continuing.

The seismic survey will also cover the area where the recent gravity survey identified numerous gravity highs. MAD202 was the first drill hole to test a gravity anomaly and successfully intersected thick intrusive-style rocks, warranting follow-up exploration. The seismic survey, as well as the completion of a DHEM survey in MAD202, will assist in the search for potential sulphide mineralisation around this hole.

See our ASX Release dated 22 June 2021 Assays Confirm High-Grade Discovery at Mt Alexander for further details of MAD202 and the seismic technique to be deployed at the Cathedrals Belt.

SCOPING STUDY FOR STARTER MINE:

The scoping study for a potential starter mine at the Stricklands deposit is advancing with two new initiatives being trialled.

Ore sorting: Ore sorting equipment can remove waste rock and ore with low concentrations of mineralisation from mined inventory resulting in an upgrade of the ore that is then processed. This can result in higher recoveries and significant savings in processing and transport costs.

A sample of semi-massive, stringer, blebby and disseminated sulphide ore from Mt Alexander will undergo a trial ore sorting process with Steinert, leading industry experts in this field.

Ore sorting can be deployed at very low cost in small or remote mining installations with the processing line planned in semi-mobile form consisting of crushers, screens, belts and sorting machines. Waste rock is disposed on-site providing greater optionality for either further efficient processing at site or transport of a high-concentrate ore to another facility.

Glycene-based leaching:

Western Australia's Curtin University has developed a new processing technology for sulphide ores that uses a glycine-based reagent to selectively leach base-metals, including nickel and copper from sulphides.

The glycine reagent is non-toxic, biodegradeable and imparts zero carbon emissions.

The process involves sulphide ores being placed in large vats where the glycine reagent is applied. A leaching process over a period of several weeks results in separation of the various metals within the sulphide ore. The metals are then recovered in a high-purity powder concentrate form and are ready for shipping to endusers.

The glycine leaching process will be trialled on a sample of nickel-copper sulphide mineralisation from Mt Alexander to test the amenability of the Mt Alexander ore to this process.

Potentially, this leaching process can be considered as an alternative to processing of ores by conventional flotation circuits – resulting in very significant savings in capital expenditure for processing facilities.

Metallurgical Test Work in Canada:

The metallurgical test work on the Stricklands ore is continuing in Canada. There have been significant delays in this test work due to ongoing COVID-19 restrictions in Canada.

Initial test work results are now expected later in Q3 2021.

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

"Our systematic step-out drilling at the Cathedrals Belt is continuing to extend the footprint of the intrusive unit that is already known to host massive nickel-copper sulphides along a strike of more than 5.5km.

"All deeper drill holes in the western part of the Cathedrals Belt have intersected intrusive-style rocks. These results indicate a very large mineral system at the Cathedrals Belt with potential for further discoveries of high-grade mineralisation in the underexplored western section of the Belt.

"The multiple EM conductors identified at West End are particularly exciting. These are favourably located within the interpreted intrusive unit and on the same plane as mineralisation intersected by recent drill holes.

"The results of the seismic survey in this area could be very important in better understanding the distribution of mineralisation in this area and planning the next drill programme for these targets.

"We are pleased to be progressing the scoping study for the potential starter mine at Stricklands. We are trialling two new processing initiatives which may materially enhance the economics of a potential starter mine.

"We look forward to providing further updates of exploration and development activities at Mt Alexander.

"We are also excited with the drilling currently underway at our Paterson Project and will provide an exploration update on that programme shortly".

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 and snap lockdowns 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.

	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.

	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.
BalancedReporting	WherecomprehensivereportingofallExplorationResultsisnotpractical,representative reporting of both low and highgrades and/or widths should be practiced toavoidmisleadingreportingofExplorationResults.
