St George Mining Limited announced further positive results from the extension and infill drill programme underway at its high-grade nickel-copper-PGE Mt Alexander Project, located in the northern Goldfields. MAD210 was completed by diamond drilling to test an EM conductor (22,500 Siemens) at Stricklands. The drill hole intersected nickel-copper sulphide mineralisation from 102.7m to 106.3m downhole, confirming further mineralisation approximately 35m to the west of the existing mineralised envelope for the Stricklands Deposit.

The mineralised intercept in MAD210 together with the result of MAD209 - which intersected nickel-copper sulphides from 112.9m to 118.1m downhole - confirm that the Stricklands Deposit is open to the west, north and north-west with potential for further drilling to delineate additional mineralisation. STRICKLANDS EXPANSION PROGRAMME CONTINUES TO DELIVER MAD210 was completed to a downhole depth of 162.4m and is located 35m to the west of the current mineralised envelope for the Stricklands Deposit and 35m to the south-west of MAD209 - which was the first expansion drill hole in the current programme and which also intersected nickel-copper sulphides. MAD210 intersected the same mineralised intrusive unit up-dip to MAD209 - confirming the extension of the interpreted mineralised intrusive at Stricklands.

The success of MAD209 and MAD210 confirms that mineralisation at Stricklands continues and remains open to the west, north and north-west. GEOLOGICAL SUMMARY Geological information on the mineralised intercept in MAD210, as well as additional information to the ASX Release dated 31 March 2022 Expansion Drill Programme - Mt Alexander regarding the mineralised intersection in MAD209, is set out below. The nature of the minerals observed in the drill core of MAD209 and MAD210 are interstitial fine-medium grained sulphides grading downhole to massive sulphide content.

This profile represents a primary mineralisation genesis that is not considered to be re-mobilised post emplacement. Descriptions of the amounts of metal sulphide observed and logged in the core are qualitative, visual estimates made by geologists on site and are listed in order of abundance of estimated combined percentages of pyrrhotite (iron mineral), pentlandite (nickel mineral), chalcopyrite (copper mineral) and pyrite (iron mineral). Visual estimates of sulphide material should not be considered a substitute for laboratory analysis, which is required to determine grade and widths for geological reporting.

Also, visual estimates potentially provide no information regarding potential impurities or deleterious physical properties of the mineralisation. Laboratory assays for MAD209 and MAD210 from Bureau Veritas in Perth are expected within 6-8 weeks and will be announced when available. The assays will confirm the nickel and copper grades as well as the values of cobalt and PGEs in the mineralised intervals.

All reported intersection widths are measured down hole. Based on the intersection angle of the drilling with the modelled intrusive unit, downhole widths for MAD209 and MAD210 noted above are interpreted to be close to true widths.
