MORE GOLD INTERCEPTS IN FIRST DRILLING AT GOORNONG PROSPECT, GREATER FOSTERVILLE PROJECT

Key Points

26 March 2024

• Multiple intervals of gold mineralisation in latest two diamond drill holes at the Goornong prospect, Greater Fosterville project
• Best new intercept of 12.3 metres @ 4.1g/t gold is 150 metres along strike from intercept of 5 metres @ 3.5 g/t gold in nearest previous hole
• Numerous gold mineralised veins now identified in 5 wide spaced holes spanning 1,500 metres of strike at the Goornong prospect
• Induced polarisation (IP) geophysics also commenced in northern part of Exploration Licence following signing of 8 access agreements with landholders

S2 Resources Ltd ("S2" or the "Company") advises that its wholly owned subsidiary, Southern Star Exploration Pty Ltd ("Southern Star"), has received the third and final batch of assay results from the last two holes of its initial six hole reconnaissance diamond drilling program at the Goornong prospect, on its 100% owned Greater Fosterville project in Victoria, Australia. It has also commenced an induced polarisation (IP) geophysics program.

Drilling at Goornong

These holes complete the Company's first reconnaissance drilling program to test the potential mineralised corridor at Goornong, which is located immediately north of Agnico Eagle's Fosterville mine lease (see Figure 1). The primary aim of this program was to define the three-dimensional architecture of folding and faulting as an initial step in vectoring into potentially favourable positions for gold mineralisation. The results so far have confirmed the geological model, identified several potentially favourable offsetting structures, and as a bonus, identified numerous zones of gold mineralisation associated with quartz veining, sulphide (arsenopyrite and stibnite) alteration, and intrusive dykes, in the form of both narrow high grade zones and broader lower grade zones.

Holes SFVD0004 and 0006 were drilled to provide information in undrilled areas between previously reported holes SFVD0003 and 0005 and tighten up the spacing between drillholes to 150-400 metres (see Figure 2). They were drilled from the same collar locations, but at differing declinations, so the hole spacing varies with depth.

Hole 4 was drilled to fill in an 800 metre gap between previous holes 3 and 5, and at the depth of interest is located approximately 300 metres south of hole 3 and 500 metres north of hole 5.

Hole 6 is the southernmost hole drilled to date, and at the depth of interest is located 150-250 metres south of the nearest hole (hole 5)

Key intercepts from hole 4 include:

• 3.0 metres @ 3.1g/t gold from 113 metres
• 13.0 metres @ 1.0g/t gold from 234 metres
• 10.0 metres @ 1.4g/t gold from 320 metres, including 0.4 metres @ 6.3g/t gold from 324.7 metres

Key intercepts from hole 6 include:

• 12.3 metres @ 4.1g/t gold from 156.7 metres, including 1.0 metre @ 11.3g/t gold from 159 metres
• 6.0 metres @ 1.8g/t gold from 270 metres
• 0.9 metres @ 6.5g/t gold from 678 metres

The presence of numerous gold mineralised structures in all five holes drilled to reconnoitre an area covering 1,500 metres of strike extent and 600 metres depth extent is considered highly encouraging, especially given the small dimensions of typical Victorian-style gold deposits and the extremely wide spacing of drilling to date.

The overall folding and fault architecture is still being interpreted to aid in understanding the potential connectivity of these mineralised zones. Further holes will be planned to infill key areas to test the outcomes of this interpretation.

Geophysics

A broad induced polarisation (IP) geophysical survey has commenced in the northern part of the tenement following the signing of eight access agreements with local farmers.

The survey covers the strike extensions of known gold-endowed structures such as the Fosterville and O'Dwyer's faults, which respectively host the Swan and Curie deposits on Agnico's Mining Lease, and which are largely concealed by shallow transported cover of the Murray basin in the northern part of the tenement.

The aim of the IP survey is to identify hotspots along these structures which may reflect the presence of disseminated sulphides which tend to indicate areas of most intense hydrothermal alteration and, by association, gold mineralisation. Previous limited IP coverage on Agnico's Mining Lease has shown a good relationship between chargeability anomalies and known sulphide alteration and gold mineralisation (see S2 ASX announcement of 16th February 2023).

It is anticipated that this survey will take approximately four weeks to complete, with work planned over multiple phases so the Company can coordinate its exploration activities with local farming requirements, and expand its coverage when further access agreements are finalised.

Map of the Goornong South area showing the diamond drill holes completed by S2 so far, gold oxide mineralised zone (historic RC drilling) and Kirkland Lake diamond drill holes drilled immediately prior to their relinquishment of the ground, aimed at testing the southerly down plunge continuation of this zone. Note, the O'Dwyer's Fault (which contains the Robbins Hill and Curie zones further south) both extend through this area.

Figure 2. Long projection of the Goornong area showing the four holes drilled parallel to the axial plane of the fold. The wide spacing of these holes at the depth of interest together with the widespread nature of gold mineralised veins, indicates the extent of the mineralising system and demonstrates the extremely broad spacing of drilling to date.

Goornong prospect background

Previous exploration has identified a strongly mineralised corridor centred on the Goornong South prospect where drilling during the 1990's intersected significant oxide gold mineralisation. During the last year that the exploration licence was held by Kirkland Lake (now Agnico Eagle) a series of diamond drill holes were completed to the south along strike of the historic oxide mineralisation. S2 Resources has been able to relog the Kirkland Lake core holes and use the information to interpret the stratigraphic and structural architecture of what is now interpreted to be the next parallel structure to the east of the O'Dwyers and Fosterville trends, which host the orebodies being mined by Agnico Eagle. This first drill program by S2 Resources, is testing immediately beneath and down plunge to the south of the Goornong South oxide mineralisation, testing multiple structures where they cross the main anticline that is interpreted to be the focus for mineralised fluids. Along the favourable anticline corridor any mineralised structure could refract into a favourable dilation position with the potential to form a significant high-grade trap for gold mineralisation akin to the Swan Zone (the Swan Zone, located along the Fosterville trend, had an initial Mineral Ore Reserve of 2.34Moz of gold at a grade of 49.6g/t, refer to the NI 43-101 Report dated 31 December 2018).

To effectively test for significant mineralisation along the Goornong South anticline trend S2 Resources has undertaken a combination of conventional across strike holes in the shallower part of the system and unconventional strike parallel holes down the axial plane of the target anticline corridor that test multiple structural positions that cross the anticline (see Figure 3). The axial plane holes were designed to test positions down plunge to the south of the oxide gold mineralisation as well as numerous other mineralised structures intersected by the historic diamond drilling completed by Kirkland Lake, anyone which could yield a significant discovery where they refract and dilate across the fold corridor.

The strike parallel holes drilling down the axial plane have broadly tested a vertical depth window of 600 metres. This allowed these drill holes to test for multiple structural levels within the anticline corridor. It is interpreted that favourable geometry for significant mineralisation will be where

structures refract into relatively flat positions across strike, where they pass through the hinge zone. Current interpretations provide for south plunging anticline hinge zones and a parallel plunge to mineralised fault intersections. Drilling was angled towards the north to provide the optimal intersection angle forsouth plunging shoots, with angled drilling enabling core orientation and detailed structural measurements which are vital to interpreting the three-dimensional position of structures relative to localstratigraphy and the overall architecture, such that any near misses can be interpreted for later drill follow-up.

The first pass drill program is designed to deliver a more detailed understanding of the structural and stratigraphic architecture of the Goornong South trend. The shallow drill holes beneath the oxide gold mineralisation will provide the first oriented core holes acrossthe entire width of the anticline corridor, proximal to significant gold mineralisation so as to provide critical information on the orientation and continuity of gold mineralised structures at this location. The deeper axial plane parallel drill holes are spaced to provide a better understanding of the distribution of alteration, the validity of the overall south plunging fold model, and the potential to identify a larger mineralised shoot early in the exploration program. Drilling was also a direct test of some specific target positions interpreted from previous drilling, as well as providing new information with which to vector towards targets in subsequent follow-up drill campaigns.

The broad spacing of these holes is tailored to finding a large gold deposit, so it is important to not be mesmerised by narrow high grade intercepts and to not drill too close too soon – a situation that can result in over-drilling and overspending fortoo few ounces defined. As previously stated, it isimportant to first understand the overall three dimensional stratigraphic and structural architecture before attempting to zero in on sweet spots.

Figure 3. Schematic block model of the Goornong area showing the south plunging fold structures and the targeted fault structures intersecting anticlines. Drilling will include both across strike (conventional) testing of mineralised structures (as shown in the cross sectional slices) and along strike (non-conventional) testing of multiple structural positions within the favourable Goornong anticline trend (as shown in the long sectional slices). Drillhole positions are illustrative only and locations may vary.

Project background

S2's 100% owned subsidiary, Southern Star Exploration Pty Ltd, was announced as the winner of the highly competitive tender for the sole right to apply for an Exploration Licence (EL) over the ground surrounding Agnico Eagle's (Agnico) world class Fosterville gold mine in October 2021 (see S2 ASX announcement of 29th October 2021). The EL application was submitted in late 2021, and various Traditional Owner-related preconditions were satisfied recently (see S2 ASX announcement of 4th July 2023). The ground was granted as Exploration Licence 7795 (EL7795) in early October (see S2 ASX announcement of 4 th October 2023), and covers an area of 394 square kilometres, extending 55 kilometres north to south, and abuts and surrounds Agnico Eagle's Fosterville mine lease. By virtue of its position, its size, and its inherent prospectivity, EL7795 is a highly strategic asset. EL7795 has a minimum expenditure commitment of A$10.4 million over the first five year term of the licence, inclusive of a minimum A$2.1 million commitment in the first two years.

As winners of the tender, S2 has also inherited a substantial amount of data acquired by previous explorers over the area, including the relatively recent exploration work undertaken by Kirkland Lake Gold (the owner of Fosterville prior to its acquisition by Agnico) on the tenement before it expired. This data includes extensive and high quality geophysical and geochemical surveys such as gravity, induced polarisation (IP), electromagnetic (EM), seismic, magnetic and LIDAR surveys, which are being

used to generate drill targets. The inheritance of such a significant amount of data represents a huge saving for the Company in terms of time and money that would otherwise be required to get it to the point of having drill ready targets for testing.

It also includes drilling data and drill core from holes drilled immediately prior to the expiry of the previous tenement, which although widely spaced and/or shallow and/or highly localised, have identified gold mineralisation in several locations. As a consequence, the Company has a range of targets at various stages of definition from early stage reconnaissance up to and including defined prospects simply requiring further drilling to determine the extent and quality of gold mineralisation at those locations.

These targets are located on a mix of Crown Land, freehold land (both broadacre farms and smaller blocks), and road reserves, which require the Company to obtain land access agreements and other relevant permits, as well as heritage clearances, before commencing exploration1 .

1 Until such time as access consents are obtained there is no guarantee that the Company will be able to access freehold property, but a substantial amount of drilling can be undertaken from roadsides.

A table of completed drill hole collar information forexploration results presented here is provided below.
Data aggregationmethods	In reporting Exploration Results, weightingaveraging techniques, maximum and/or minimumgrade truncations (e.g. cutting of high grades) andcut-off grades are usually Material and should bestated.	All Exploration Results reported are downhole weightedmeans.
	Where aggregate intercepts incorporate shortlengths of high grade results and longer lengths oflow grade results, the procedure used for suchaggregation should be stated and some typicalexamples of such aggregations should be shown indetail.	A table of significant intercepts presented here is providedbelow.
	The assumptions used for any reporting of metalequivalent values should be clearly stated.	No metal equivalent values are reported.
Relationshipbetweenmineralisationwidths and interceptlengths	These relationships are particularly important inthe reporting of Exploration Results.If the geometry of the mineralisation with respectto the drill hole angle is known, its nature shouldbe reported.If it is not known and only the down hole lengthsare reported, there should be a clear statement tothis effect (e.g. 'down hole length, true width notknown').	The relationship between mineralization and drill holeangle is not fully understood, therefore the down holemineralized and composited lengths are shown. A truewidth is not known at this time.
