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

Key Points

Assays received for the first (SFVD0007) of two follow-up diamond drill holes at the Goornong prospect, Greater Fosterville
Multiple intervals of gold mineralisation intersected, including 5.7 metres @ 6.4g/t gold
This is 150 metres from the intercept of 10.2 metres @ 4.2 g/t gold on the same interpreted structure in SFVD0005 to the north
Numerous gold mineralised veins now identified in 6 wide spaced holes spanning 1,500 metres of strike at the Goornong prospect
Induced polarisation (IP) geophysics has identified two broad areas of chargeability anomalism with more discrete structural positions within the broad anomalism providing areas for future focused follow-up exploration activities.

S2 Resources Ltd (“S2” or the “Company”) advises that its wholly owned subsidiary, Southern Star Exploration Pty Ltd (“Southern Star”), has received assay results for the first of two follow-up holes at the Goornong prospect, on its 100% owned Greater Fosterville project in Victoria, Australia. Results for the second hole are awaited.

Drilling at Goornong

S2 has completed two diamond drill holes to follow up gold mineralisation intersected in the first six holes drilled at the Goornong prospect, located immediately north of Agnico Eagle’s Fosterville mining lease (see Figure 1). The first six holes identified numerous zones of gold mineralisation in very widely spaced holes (see S2 ASX announcement of 26 March 2024 and Figure 2). Two initial follow up holes (SFVD0007 and 0008) were drilled to assess the degree of connectivity or otherwise of the gold mineralised zones identified to date.

SFVD0007 was designed to test the strike position in between SFVD0005 and SFVD0006 but in a position 25-50 metres east of the axial plane tested by the earlier holes, to allow an assessment of not

only any along strike continuity of mineralised structures, but importantly their persistence up/down dip to the east as they passed into the eastern limb of the primary anticline.

The strongest new intercept of 5.7 metres @ 6.4g/t gold in hole SFVD0007 is geologically similar to a mineralised zone some 150 metres away in the nearest hole to the north (hole SFVD0005) that comprises 10.2 metres @ 4.2g/t gold. These intercepts may be the same structure, and if so, indicate the presence of significant gold mineralisation over a significant strike extent.

Assays are awaited for SFVD008, which was designed primarily to drill back towards the south to fill a large gap (400-600 metres) between mineralised intervals intersected in SFVD0004 & SFVD0005, as well as also being sited 25-50 metres east of the anticline.

The Company is now assessing in detail the nature of each mineralised zone using a combination of structural observations, alteration characteristics and multi-element analysis to build a threedimensional interpretation of the folding and faulting architecture. This understanding will then be used to further zero in on target positions for potentially significant accumulations of gold mineralisation by vectoring along the more favourable structures.

Key intercepts from hole 7 include:

6.5 metres @ 1.5g/t gold from 214.5 metres, including 0.6 metres @ 7.5g/t gold from 215.4 metres
2.0 metres @ 2.5g/t gold from 241 metres
3.0 metres @ 3.7g/t gold from 266 metres
5.7 metres @ 6.4g/t gold from 344 metres, including 2.15 metres @ 14.1g/t gold from 247.55 metres

Previous holes intersected significant gold mineralisation in structures within the same depth interval (from surface to 350 metres depth) over a strike length spanning 1,500 metres (Figure 2). The holes completed by S2 at the southern end of the trend have to date shown a complex clustering of significant gold mineralised faults with variable associated quartz vein development. Mineralisation is closely associated with disseminated sulphide (pyrite-arsenopyrite) alteration zones around faults, with variable presence of stibnite both coarsely crystalline within veins and as finer disseminations.

Key intercepts within this broad zone of complex mineralised structures from previous drilling adjacent to holes 7 & 8 include:

3.0 metres @ 3.1g/t gold from 113 metres (SFVD0004)
13.0 metres @ 1.0g/t gold from 234 metres (SFVD0004)
10.0 metres @ 1.4g/t gold from 320 metres, including 0.4 metres @ 6.3g/t gold from 324.7 metres (SFVD0004)
5.0 metres at 3.5g/t gold from 319 metres (SFVD0005)
6.2 metres at 1.9g/t gold from 395 metres (SFVD0005)
0.7 metres at 6.9g/t gold from 409.6 metres (SFVD0005)
3.0 metres at 2.5g/t gold from 430 metres (SFVD0005)
4.0 metres at 1.3g/t gold from 453 metres (SFVD0005)

Geophysics

The first phase of a broad induced polarisation (IP) geophysical survey was completed in the northern part of the tenement following the signing of eight (8) land access agreements with local farmers.

The survey area 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 (see Figure 3).

The first phase of IP successfully identified two significant broad chargeability anomalies. The first broad anomaly covers the extensions of the mineralised structures north of the Fosterville Mine, including the Goornong mineralised zone which is the focus of current diamond drilling, and the O’Dwyer’s and Fosterville faults. The chargeability anomalism parallels and in some areas is offset from the interpreted faults, perhaps representing down-dip positions of more focused sulphide accumulations. A particularly strong anomaly is located at a structural intersection of the north trending Fosterville Fault and a NW trending cross fault.

The second broad anomaly is more loosely defined by broad traverses completed in the north-east corner of the licence, adjacent and east of the historic May Reef prospect. This area of cover east of Bendigo Creek has had no previous exploration despite being in a favourable position adjacent and to the west of the Redesdale Fault.

A second phase of broad IP is planned later in the year as part of the Company’s strategy in working with landowners around local farming requirements. The second phase of work will add to the regional coverage and also work on advancing the definition of targets within the two broad anomalous zones.

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 is undertaking 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 4). The axial plane holes are 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 will continue to 800 metres depth. This will allow 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 is angled towards the north to provide the optimal intersection angle for south 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 local stratigraphy 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 across the 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 will be 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 for too few ounces defined. As previously stated, it is important to first understand the overall three dimensional stratigraphic and structural architecture before attempting to zero in on sweet spots.

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 29[th] October 2021). The EL application was submitted in late 2021, and various Traditional Owner-related preconditions were satisfied recently (see S2 ASX announcement of 4[th] 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 exploration[1] .

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.

This announcement has been provided to the ASX under the authorisation of the S2 Board.

The following Tables are provided to ensure compliance with the JORC code (2012) edition requirements for the reporting of exploration results.

SECTION 1: SAMPLING TECHNIQUES AND DATA

Criteria	JORC Code explanation	Commentary
Sampling techniques	Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.	Historic drilling from surface includes diamond core and Reverse Circulation (RC). All historical drilling data has been obtained from open file reporting, the majority which was compiled and reported by Kirland Lake Gold in the EL3539 Final Relinquishment Report (2019). Data has been reviewed, appraised and integrated into a database. Data is of sufficient quality, relevance and applicability. All 2023-24 drilling was diamond core drilling from surface completed by Deepcore Australia Pty Ltd, based out of Bendigo, Victoria.
	Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used	No information about the historic QAQC procedures have been compiled. All 2023-24 core is split in half by core saw for external laboratory preparation and analysis.
	Aspects of the determination of mineralisation that are Material to the Public Report. In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information	Historic sampling intervals were typically 0.3 to 2.0m for core and 1 to 4m for RC. Core was typically split in half by core saw. All samples were sent to an external laboratory for preparation and analysis. Based on the distribution of mineralisation the sample size is considered adequate for representative sampling. Based on the distribution of mineralisation the core sample size is considered adequate for representative sampling.
Drilling techniques	Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc).	Historic drilling from surface includes diamond core and Reverse Circulation (RC). Diamond core is oriented. No details about hole diameter have been compiled. All 2023-24 drilling was diamond core from surface, HQ and NQ3 size. NQ3 core is triple tube wireline. Core orientation uses the Axis Camp Ori tool.
Drill sample recovery	Method of recording and assessing core and chip sample recoveries and results assessed	Historic core recoveries have been compiled. No information about historic chip sample recoveries has been compiled. 2023-24 drilling methods are selected to ensure maximum recovery possible.
	Measures taken to maximise sample recovery and ensure representative nature of the samples	No historic information about maximising sample recovery has been compiled. 2023-24 core recovery is collected in a set of standard Excel templates then transferred to the digital database.
	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.	A link between sample recovery and grade is not apparent.


Criteria	JORC Code explanation	Commentary
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.	The compilation of historic diamond core and RC drilling includes records of lithology, alteration, structure and recovery. All 2023-24 diamond core undergoes geotechnical and geological logging to a level of detail (quantitative and qualitative) sufficient to support use of the data in all categories of Mineral Resource estimation. Diamond core logging includes records of lithology, alteration, veining, structure and recovery.
	Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography.	The compilation of historic diamond core and RC logging is quantitative and qualitative. Core photography is available. All 2023-24 core is photographed.
	The total length and percentage of the relevant intersections logged	The compilation of historic diamond core and RC logging is comprehensive for all exploration results reported. S2R geologists and consultants have been able to relog 80% of the core for the Goornong South prospect. All 2023-24 drill holes are logged in full.
Sub-sampling techniques and sample preparation	If core, whether cut or sawn and whether quarter, half or all core taken.	Core is split in half by core saw and one-half sampled and submitted to the laboratory for analysis.
	If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry.	No non-core sampling was compiled.
	For all sample types, the nature, quality and appropriateness of the sample preparation technique.	Historic samples were submitted to reputable commercial laboratories (OSLS Bendigo and Bureau Veritas Adelaide) that used standard industry preparation techniques. 2023-24 core samples are submitted to On Site Laboratory Services (OSLS, Bendigo) and undergo standard industry procedure sample preparation (crush, pulverise and split) appropriate to the sample type and mineralisation style.
	Quality control procedures adopted for all sub- sampling stages to maximise representivity of samples.	Historic reports note QAQC protocols but no data has been compiled to assess the QAQC results. Full QAQC system is in place for 2023-24 core assays to determine accuracy and precision of assays.
	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.	No information regarding the representativity of the historic sampling has been compiled. 2023-24 core is cut to achieve non-biased samples. No duplicate samples have been collected at this stage.
	Whether sample sizes are appropriate to the grain size of the material being sampled.	Sample sizes are appropriate to the grain size of the material being sampled.


Criteria	JORC Code explanation	Commentary
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.	Historic core and RC samples were analysed for Au by OSLS (Bendigo) using a 25g fire assay with AAS finish (PE01S) or by Bureau Veritas (Adelaide) using a 40g fire assay with AAS finish (FA001). Historic core and RC samples were analysed for a variable suite of multi-elements by OSLS (Bendigo) using method B010 (aqua regia digest and ICP-AES finish) or by Bureau Veritas (Adelaide) by technique MA101/102 (four acid digest and ICP-AES/MS finish). Historic assay for Au is considered total. Multi-element assay four acid digest are considered near-total for all but the most resistive minerals (not of relevance). Aqua-regia digestion is considered partial depending on element and minerals present, but sulphide minerals as seen on the project are readily and completely digestible. Core samples are submitted to OSLS (Bendigo) for analysis. Au is assayed using a 25g fire assay with AAS finish (PE01S). A multi-element suite of 32 elements is assayed by technique BM020/ICP050 (1g charge by four acid digest and ICP-MS finish). The nature and quality of the analytical technique is deemed appropriate for the mineralisation style. Fire assay for Au is considered total. Multi-element assay four acid digest are considered near-total for all but the most resistive minerals (not of relevance).
	For geophysical tools, spectrometers, handheld XRF instruments, etc, the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc.	No geophysical tools were used to determine any element concentrations.
	Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established.	Historic reports note QAQC protocols, but no data has been compiled to assess the QAQC results. Full QAQC system is in place for 2023-24 core sample assays including blanks and standards (relevant certified reference material).
Verification of sampling and assaying	The verification of significant intersections by either independent or alternative company personnel.	All assay results are checked and verified by alternative company personnel or independent consultants. Significant assay results prompt a visual review of relevant reference core for validation purposes.
	The use of twinned holes.	No twin holes are reported.
	Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.	All historical drilling data has been obtained from open file reporting, the majority which was compiled and reported by Kirland Lake Gold in the EL3539 Final Relinquishment Report (2019). Data has been reviewed, appraised and integrated into S2’s central database. For 2023-24 drilling the primary sampling data is collected in a set of standard Excel templates. The information is managed by S2’s database manager for validation and compilation into S2’s central database.
	Discuss any adjustment to assay data.	No adjustments made.


Criteria	JORC Code explanation	Commentary
Location of data points	Accuracy and quality of surveys used to locate drillholes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.	Most historic drill collar locations were recorded using a handheld GPS with a small number of drill collars recorded using a differential GPS. All 2023-24 diamond drill holes are surveyed by handheld GPS in the first instance. All 2023-24 diamond drill holes are surveyed downhole using the Axis Champ Gyro at approximately 12m intervals to determine accurate drill trace locations. There is no magnetic interference with respect to downhole surveys.
	Specification of the grid system used.	The grid system is MGA GDA94 (Zone 55). Local easting and northing are in MGA.
	Quality and adequacy of topographic control.	Topographic control is provided by a high-resolution LiDAR survey DEM. The accuracy of the DEM is +/-1m.
Data spacing and distribution	Data spacing for reporting of Exploration Results.	Data spacing (drill holes) is variable and appropriate to the geology.
	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.	No Mineral Resource or Ore Reserve estimation is reported.
	Whether sample compositing has been applied.	No sample compositing has been applied.
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 may not necessarily be perpendicular to the orientation of the intersected mineralisation. Mineralised structures have multiple orientations. Some of the mineralised structures are intersected at low angles to the drill holes resulting in multiple intersections of the same mineralised structure, though for the majority of drilling there is no significant orientation-based sampling bias. Reported intersections are down-hole intervals and not true widths.
	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.	Where the drilling orientation intersects a mineralised structure at a low angle appropriate commentary is provided in the body of the report.
Sample security	The measures taken to ensure sample security.	No information regarding the historic sample security has been compiled. Chain of custody is managed by S2 personnel. Drill core is visually checked at the drill rig and then transported to S2’s Bendigo facility where it is cut and sampled before being secured in bags with a security seal. Bagged samples are transported to the OSLS laboratory in Bendigo by S2 personnel.
Audits or reviews	The results of any audits or reviews of sampling techniques and data.	No records of any audits or reviews of historic sampling have been compiled to date. No audits or reviews have been conducted for 2023-24 drilling activities.

SECTION 2: REPORTING OF EXPLORATION RESULTS

Criteria	JORC Code explanation	Commentary
Mineral tenement and land tenure status	Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings.	The Greater Fosterville Project consists of two granted exploration licences (EL7795 & EL8074) and two deferred exploration licence applications (EL8166 & EL8167) in the State of Victoria. The tenements are owned by Southern Star Exploration Pty Ltd (SSE), a wholly owned subsidiary of S2 Resources Ltd. The Greater Fosterville Project is located within Recognition and Settlement Agreement Areas held by the Dja Dja Wurrung Clans Aboriginal Corporation (DJAARA) and the Taungurung Land and Waters Council Aboriginal Corporation (TLaWC) under the Traditional Owner Settlement Act 2010 (Vic). Access and compensation agreements are required to conduct work on freehold land and while it is hoped that landowners will agree to these there is no guarantee that they will be forthcoming.
	The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.	EL7795 & EL8074 are current and in good standing. EL8166 & EL8167 are deferred applications following a competitive assessment that resulted in the government selecting an alternate preferred applicant. EL8166 & EL8167 will remain in abeyance until the highest ranked application is either granted or refused.
Exploration done by other parties	Acknowledgment and appraisal of exploration by other parties.	The Greater Fosterville Project has seen exploration conducted by the various owners of the Fosterville Gold Mine that has included Perseverance Exploration Company Ltd, Northgate Minerals, AuRico Gold, Crocodile Gold, Newmarket and Kirkland Lake Gold over the period 1989- 2019. Historic exploration has also included work by Planet Mining Company Pty Ltd (1965-70), Lone Star Exploration NL (1973-74), Noranda Australia Ltd (1974-76), Brunswick NL (1989-92), Bendigo Gold Associates (1989-92), BHP Minerals Ltd (1986-90), Western Mining Corporation Limited (1978-89) and Rio Tinto Exploration Pty Ltd (1980- 1988). All historical work has been obtained from open file reporting, the majority which was compiled and reported by Kirland Lake Gold in the EL3539 Final Relinquishment Report (2019). Data has been reviewed, appraised and integrated into a database. Data is of sufficient quality, relevance and applicability.
Geology	Deposit type, geological setting and style of mineralisation.	The deposit style sought is orogenic gold mineralisation located in the Bendigo Zone of the Victorian Gold Province. The Fosterville Goldfield is hosted by Lower Ordovician turbidites within the Castlemaine Group rocks. The sequence is metamorphosed to sub-greenschist facies. Gold mineralisation is typically hosted by quartz reefs located in fold and fault structures related to multiple compression events that formed upright chevron style fold geometry.


Criteria	JORC Code explanation	Commentary
Drill hole Information	A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: • easting and northing of the drill hole collar • elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar • dip and azimuth of the hole • down hole length and interception depth • hole length.	A table of completed drill hole collar information for exploration results presented here is provided below.
Data 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.	All Exploration Results reported are downhole weighted means.
	Where aggregate 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.	A table of significant intercepts presented here is provided below.
	The assumptions used for any reporting of metal equivalent values should be clearly stated.	No metal equivalent values are reported.
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 (e.g. ‘down hole length, true width not known’).	The relationship between mineralization and drill hole angle is not fully understood, therefore the down hole mineralized and composited lengths are shown. A true width is not known at this time.
Diagram	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 plan view of drill hole collar locations and appropriate sectional views.	Appropriate maps, sections and tables are included in the body of the report.
Balanced reporting	Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.	Maps showing individual sample locations are included in the report. All results considered significant are reported.
Other substantive exploration data	Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.	Previous exploration data reported include historic dipole- dipole IP-resistivity surveys (ASX Announcement 17 February 2023), historic RC and diamond drilling (ASX Announcement 20 October 2023) and earlier diamond drilling from the current program (ASX Announcements 27 December 2023 & 15 February 2024). Other historical exploration data has not yet been compiled to a level where it can be reported. Further compilation of such data will be reviewed and reported when considered material.


Criteria	JORC Code explanation	Commentary
Further work	The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling). Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive	The initial diamond drilling program to test targets defined by historical data at Goornong South has been completed, with the overall folding and fault architecture still being interpreted to aid in understanding the potential connectivity of the mineralised zones. A further program of holes will be planned to infill key areas to test the outcomes of this interpretation. Broader surface exploration activities including IP-resistivity to generate new targets have commenced.
