Southern Cross Gold Expands Golden Dyke with 5.4 m @ 29.6 g/t Gold Intercept

Reports Three +50 AuEq g/t x m Intercepts

Vancouver, Canada and Melbourne, Australia–(Newsfile Corp. – March 26, 2025) – Southern Cross Gold Consolidated Ltd (TSXV: SXGC) (ASX: SX2) (OTC Pink: MWSNF) (FSE: MV3) (“Southern Cross Gold” or the “Company”) announces results from two drill holes: SDDSC147 and SDDSC151 at the Golden Dyke prospect, part of the 100%-owned Sunday Creek Gold-Antimony project in Victoria (Figure 4).

5 KEY TAKEAWAYS

The two drillholes are the deepest east-west oriented holes at Golden Dyke prospect at Sunday Creek.

SDDSC151 delivered three significant intercepts exceeding 50 gram-metres AuEq, including 5.4 m @ 29.6 g/t Au. This demonstrates continuing high-grade mineralization that enhances the economic potential of the deposit and contributes to the project’s growing inventory of +100 g/t AuEq x m intercepts (61 intersected to date).

The discovery of a high-grade zone (3.2 m @ 18.0 g/t Au) in SDDSC151 hosted within a previously unrecognized sub-parallel dyke at 382.2 m depth is geologically significant. This represents a new structural position within the mineralized system, indicating potential for additional parallel structures that could substantially expand the resource footprint.

Intercepts including 1.2 m @ 96.7 g/t Au, 0.1 m @ 270.0 g/t Au and 0.4 m @ 129.6 g/t Au, represent extremely high-grade central zones within each vein system. These are characteristic of Victorian epizonal gold-antimony deposits, suggesting similar deposit genesis and potential for additional high-grade shoots at depth.

Sunday Creek project is a rare asset, being one of the only Tier 1 independently owned, high-grade, multi-million ounce potential greenfield global projects. Global investors in gold are seeking consolidation and are once again supportive of growth via high-quality acquisitions. Gold companies have suffered from an under-investment in new projects which has materially increased the scarcity value for new projects that deliver high-grade ounces in low-risk jurisdictions – attributes that Sunday Creek is almost unique in holding with limited global peers. The Company is executing an accelerated exploration strategy with six active drill rigs and a planned 60,000 m program through Q3 2025, backed by A$18M in cash reserves.

Michael Hudson, President & CEO of SXGC states: “Golden Dyke continues to deliver exceptional high-grade results. The discovery of a new high-grade structure in SDDSC151 has substantial implications for expanding our resource potential, giving an intriguing hint of the parallel mineralized systems throughout the project. Consistent extremely high-grade intercepts across multiple high-grade structures in the same hole including hits like 1.2 m @ 96.7 g/t Au, 1.4 m @ 37.3 g/t Au and 0.4 m @ 129.6 g/t Au, surrounded by broader halos demonstrate the extraordinary richness of this system.

“With 61 intersections exceeding 100 g/t AuEq x m from just 75 km of drilling, we’re seeing mineralization signatures that place Sunday Creek firmly as globally significant gold-antimony system that Victoria is now recognized for, having produced two globally significant gold discoveries in the last decade. Our six-rig drilling program underscores our confidence in rapidly advancing this strategic asset that combines exceptional gold economics with critical antimony exposure at a time of increasing geopolitical importance.

“The Sunday Creek project is the one of the only Tier 1 independently owned, greenfield and high-grade, projects globally with multi-million ounce potential. Gold companies have suffered from an under-investment in new projects which has materially increased the scarcity value for new projects that deliver high-grade ounces in low-risk jurisdictions – attributes that Sunday Creek is almost unique in holding with limited global peers.”

FOR THOSE WHO LIKE THE DETAILS

HIGHLIGHTS

Two drillholes SDDSC151 and SDDSC147 were designed to test extensions to depth and strike potential of vein sets at the Golden Dyke prospect. Mineralization was intercepted at depths of 320 m to 620 m vertically from the surface. The two drillholes are the deepest east-west oriented holes at Golden Dyke and represent a 90 m to 120 m down dip extension (from SDDSC141, reported 28 November, 2024). Mineralization was successfully drilled up to 30 m along strike between the two holes in a NW-SE orientation (along the rungs of the ladder) (Figures 1 and 2).

SDDSC151 drilled a 120 m zone of mineralization in the footwall zone at Golden Dyke. The hole intersected four vein sets from 382.2 m depth. The hole included nine intercepts >20 g/t Au (up to 270 g/t Au) and one interval exceeding 100 gram-metres gold equivalent (“AuEq g/t x m”) and two intervals between 50 and 100 AuEq g/t x m. Selected highlights include:

3.2 m @ 18.0 g/t Au from 382.2 m including:

0.4 m @ 129.6 g/t Au from 382.4 m

5.4 m @ 29.6 g/t Au from 584.3 m including:

1.2 m @ 96.7 g/t Au from 585.0 m

4.2 m @ 13.2 g/t Au from 604.5 m including:

1.4 m @ 37.3 g/t Au from 606.8 m

0.4 m @ 78.7 g/t Au from 641.2 m including: 

0.1 m @ 270.0 g/t Au from 641.2 m

SDDSC147 drilled a 235 m zone of mineralization in the hanging wall zone at Golden Dyke. This hole intercepted three vein sets at distal/peripheral locations. Highlights include:

1.3 m @ 7.9 g/t Au from 19.3 m 

1.3 m @ 9.3 g/t Au from 134.4 m, including:

0.9 m @ 11.3 g/t Au from 134.7 m

3.2 m @ 1.0 g/t Au from 805.0 m

Ongoing Exploration: A$18 million in cash and no debt. Fifteen holes currently being processed and analysed. Six additional holes are being drilled.

Drill Hole Discussion

Mineralization in SDDSC147 and SDDSC151 was intercepted between vertical depths of 320 m to 620 m from the surface (130 m to 445 m below the base of Golden Dyke workings). The two drillholes are the deepest east-west oriented holes at Golden Dyke and represent a 90 m to 120 m down dip extension (from SDDSC141, reported 28 November, 2024) of multiple mineralized structures (Figures 1 and 2).

SDDSC151 was drilled to test the footwall (FW) and intersected four distinct vein sets along with a high-grade (HG) zone hosted within a sub-parallel and sub-vertical dyke at 382.2 m depth. This is important as this previously unrecognized host position demonstrates upside to expand mineralization at Golden Dyke in potential parallel zones. The hole drilled a 120 m zone of mineralization in the footwall zone at Golden Dyke. Notably, the hole returned:

One interval exceeding 100 gram-metres AuEq

5.4 m @ 29.8 g/t AuEq (29.6 g/t Au, 0.1% Sb) from 584.3 m

Two intervals between 50 and 100 gram-metres AuEq

3.2 m @ 18.0 g/t AuEq (18.0 g/t Au, 0.0% Sb) from 382.2 m

4.2 m @ 13.5 g/t AuEq (13.2 g/t Au, 0.1% Sb) from 604.5 m

Extended highlights include:

3.2 m @ 18.0 g/t AuEq (18.0 g/t Au, 0.0% Sb) from 382.2 m

0.4 m @ 129.7 g/t AuEq (129.6 g/t Au, 0.0% Sb) from 382.4 m

0.2 m @ 16.1 g/t AuEq (16.1 g/t Au, 0.0% Sb) from 430.7 m

5.4 m @ 29.8 g/t AuEq (29.6 g/t Au, 0.1% Sb) from 584.3 m

4.7 m @ 33.7 g/t AuEq (33.5 g/t Au, 0.1% Sb) from 585.0 m

0.6 m @ 4.2 g/t AuEq (4.1 g/t Au, 0.1% Sb) from 596.2 m

4.2 m @ 13.5 g/t AuEq (13.2 g/t Au, 0.1% Sb) from 604.5 m

1.4 m @ 37.3 g/t AuEq (37.3 g/t Au, 0.0% Sb) from 606.8 m

0.3 m @ 9.0 g/t AuEq (2.8 g/t Au, 2.6% Sb) from 624.9 m

0.4 m @ 78.7 g/t AuEq (78.7 g/t Au, 0.0% Sb) from 641.2 m

0.1 m @ 270.0 g/t AuEq (270.0 g/t Au, 0.0% Sb) from 641.2 m

SDDSC147 drilled a 235 m zone of mineralization in the hanging wall zone at Golden Dyke, expanding the potential strike length and demonstrating continuity of mineralization. The broad prospective window reinforces the geological model and provides additional targets for follow-up drilling. Highlights include:

1.3 m @ 8.0 g/t AuEq (7.9 g/t Au, 0.0% Sb) from 19.3 m

1.3 m @ 9.3 g/t AuEq (9.3 g/t Au, 0.0% Sb) from 134.4 m

0.9 m @ 11.3 g/t AuEq (11.3 g/t Au, 0.0% Sb) from 134.7 m

3.2 m @ 1.0 g/t AuEq (1.0 g/t Au, 0.0% Sb) from 805.0 m

Pending Results and Update

The drilling programme continues to advance with fifteen holes (SDDSC149, 149W1, 152, 154-160, 155A, 157A, 163, 164, 165) currently being processed and analysed. Six additional holes (SDDSC160W1, 161, 162, 163A, 166, 167) are actively being drilled.

The drilling strategy employs a systematic approach to intersect both the dyke host structure (“ladder rails”) and associated mineralized vein sets (“ladder rungs”) at optimal angles, continuing to expand the project’s mineralized footprint while improving geological understanding of the system.

About Sunday Creek

The Sunday Creek epizonal-style gold project is located 60 km north of Melbourne within 16,900 hectares (“Ha”) of granted exploration tenements (Figure 3). Southern Cross Gold is also the freehold landholder of 1,054.51 Ha that forms the key portion in and around the main drilled area at the Sunday Creek Project,

Gold and antimony form in a relay of vein sets that cut across a steeply dipping zone of intensely altered rocks (the “host”). These vein sets are like a “Golden Ladder” structure where the main host extends between the side rails deep into the earth, with multiple cross-cutting vein sets that host the gold forming the rungs. At Apollo and Rising Sun these individual ‘rungs’ have been defined over 600 m depth extent from surface to over 1,100 m below surface, are 2.4 m to 3.8 m wide (median widths) (and up to 10 m), and 20 m to 100 m in strike.

Cumulatively, 164 drill holes for 75,013.51 m have been reported from Sunday Creek since late 2020. An additional 12 holes for 582.55 m from Sunday Creek were abandoned due to deviation or hole conditions. Fourteen drillholes for 2,383 m have been reported regionally outside of the main Sunday Creek drill area. A total of 64 historic drill holes for 5,599 m were completed from the late 1960s to 2008. The project now contains a total of sixty-one (61) >100 g/t AuEq x m and sixty-nine (69) >50 to 100 g/t AuEq x m drill holes by applying a 2 m @ 1 g/t AuEq lower cut.

Our systematic drill program is strategically targeting these significant vein formations, initially these have been defined over 1,500 m strike of the host from Christina to Apollo prospects, of which approximately 620 m has been more intensively drill tested (Rising Sun to Apollo). At least 70 ‘rungs’ have been defined to date, defined by high-grade intercepts (20 g/t to >7,330 g/t Au) along with lower grade edges. Ongoing step-out drilling is aiming to uncover the potential extent of this mineralized system (Figure 3).

Geologically, the project is located within the Melbourne Structural Zone in the Lachlan Fold Belt. The regional host to the Sunday Creek mineralization is an interbedded turbidite sequence of siltstones and minor sandstones metamorphosed to sub-greenschist facies and folded into a set of open north-west trending folds.

Further Information

Further discussion and analysis of the Sunday Creek project is available through the interactive Vrify 3D animations, presentations and videos all available on the Southern Cross Gold’s website. These data, along with an interview on these results with Managing Director Michael Hudson can be viewed at www.southerncrossgold.com

No upper gold grade cut is applied in the averaging and intervals are reported as drill thickness. However, during future Mineral Resource studies, the requirement for assay top cutting will be assessed. The Company notes that due to rounding of assay results to one significant figure, minor variations in calculated composite grades may occur.

Figures 1 to 4 show project location, plan and longitudinal views of drill results reported here and Tables 1 to 3 provide collar and assay data. The true thickness of the mineralized intervals reported is approximately 30-50% of the sampled thickness for other reported holes. Lower grades were cut at 1.0 g/t AuEq lower cutoff over a maximum width of 2 m with higher grades cut at 5.0 g/t AuEq lower cutoff over a maximum of 1 m width unless specified unless otherwise* specified to demonstrate higher grade assays.

Critical Metal Epizonal Gold-Antimony Deposits

Sunday Creek (Figure 4) is an epizonal gold-antimony deposit formed in the late Devonian (like Fosterville, Costerfield and Redcastle), 60 million years later than mesozonal gold systems formed in Victoria (for example Ballarat and Bendigo). Epizonal deposits are a form of orogenic gold deposit classified according to their depth of formation: epizonal (<6 km), mesozonal (6-12 km) and hypozonal (>12 km).

Epizonal deposits in Victoria often have associated high levels of the critical metal, antimony, and Sunday Creek is no exception. China claims a 56 per cent share of global mined supplies of antimony, according to a 2023 European Union study. Antimony features highly on the critical minerals lists of many countries including Australia, the United States of America, Canada, Japan and the European Union. Australia ranks seventh for antimony production despite all production coming from a single mine at Costerfield in Victoria, located nearby to all SXG projects. Antimony alloys with lead and tin which results in improved properties for solders, munitions, bearings and batteries. Antimony is a prominent additive for halogen-containing flame retardants. Adequate supplies of antimony are critical to the world’s energy transition, and to the high-tech industry, especially the semi-conductor and defence sectors where it is a critical additive to primers in munitions.

In August 2024, the Chinese government announced it will place export limits from September 15, 2024 on antimony and antimony products. This puts pressure on Western defence supply chains and negatively affect the supply of the metal and push up pricing given China’s dominance of the supply of the metal in the global markets. This is positive for Southern Cross Gold as we are likely to have one of the very few large and high-quality projects of antimony in the western world that can feed western demand into the future.

Antimony represents approximately 21 to 24% in situ recoverable value of Sunday Creek at an AuEq of 2.39.

Southern Cross Gold Consolidated Ltd is now dual listed on the TSXV (SXGC) and ASX (SX2)

About Southern Cross Gold Consolidated Ltd. (TSXV: SXGC) (ASX: SX2)

Southern Cross Gold Consolidated Ltd. (TSXV: SXGC) (ASX: SX2) controls the Sunday Creek Gold-Antimony Project located 60 kilometres north of Melbourne, Australia. Sunday Creek has emerged as one of the Western world’s most significant gold and antimony discoveries, with exceptional drilling results including 61 intersections exceeding 100 g/t AuEq x m from just 75 km of drilling. The mineralization follows a “Golden Ladder” structure over 12 km of strike length, with confirmed continuity from surface to 1,100 m depth.

Sunday Creek’s strategic value is enhanced by its dual-metal profile, with antimony contributing 20% of the in-situ value alongside gold. This has gained increased significance following China’s export restrictions on antimony, a critical metal for defence and semiconductor applications. Southern Cross’ inclusion in the US Defence Industrial Base Consortium (DIBC) and Australia’s AUKUS-related legislative changes position it as a potential key Western antimony supplier. Importantly, Sunday Creek can be developed primarily based on gold economics, which reduces antimony-related risks while maintaining strategic supply potential.

Technical fundamentals further strengthen the investment case, with preliminary metallurgical work showing non-refractory mineralization suitable for conventional processing and gold recoveries of 93-98% through gravity and flotation.

With A$18M in cash, over 1,000 Ha of strategic freehold land ownership, and a large 60 km drill program planned through Q3 2025, Southern Cross Gold is well-positioned to advance this globally significant gold-antimony discovery in a tier-one jurisdiction.

NI 43-101 Technical Background and Qualified Person

Michael Hudson, President and CEO and Managing Director of Southern Cross Gold, and a Fellow of the Australasian Institute of Mining and Metallurgy, and Mr Kenneth Bush, Exploration Manager of Southern Cross Gold and a Member of Australian Institute of Geoscientists, are the Qualified Persons as defined by the NI 43-101. They have reviewed, verified and approved the technical contents of this release.

Analytical samples are transported to the Bendigo facility of On Site Laboratory Services (“On Site”) which operates under both an ISO 9001 and NATA quality systems. Samples were prepared and analyzed for gold using the fire assay technique (PE01S method; 25 g charge), followed by measuring the gold in solution with flame AAS equipment. Samples for multi-element analysis (BM011 and over-range methods as required) use aqua regia digestion and ICP-MS analysis. The QA/QC program of Southern Cross Gold consists of the systematic insertion of certified standards of known gold and antimony content, blanks within interpreted mineralized rock and quarter core duplicates. In addition, On Site inserts blanks and standards into the analytical process.

Southern Cross Gold considers that both gold and antimony that are included in the gold equivalent calculation (“AuEq”) have reasonable potential to be recovered at Sunday Creek, given current geochemical understanding, historic production statistics and geologically analogous mining operations. Historically, ore from Sunday Creek was treated onsite or shipped to the Costerfield mine, located 54 km to the northwest of the project, for processing during WW1. The Costerfield mine corridor, now owned by Mandalay Resources Ltd contains two million ounces of equivalent gold (Mandalay Q3 2021 Results), and in 2020 was the sixth highest-grade global underground mine and a top 5 global producer of antimony.

Southern Cross Gold considers that it is appropriate to adopt the same gold equivalent variables as Mandalay Resources Ltd in its 2024 End of Year Mineral Reserves and Resources Press Release, dated February 20, 2025. The gold equivalence formula used by Mandalay Resources was calculated using Costerfield’s 2024 production costs, using a gold price of US$2,500 per ounce, an antimony price of US$19,000 per tonne and 2024 total year metal recoveries of 91% for gold and 92% for antimony, and is as follows:

AuEq = Au (g/t) + 2.39 x Sb (%).

Based on the latest Costerfield calculation and given the similar geological styles and historic toll treatment of Sunday Creek mineralization at Costerfield, Southern Cross Gold considers that a AuEq = Au (g/t) + 2.39 x Sb (%) is appropriate to use for the initial exploration targeting of gold-antimony mineralization at Sunday Creek.

Section 1 Sampling Techniques and Data

CriteriaJORC Code explanationCommentarySampling techniquesNature 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.Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.Aspects of the determination of mineralization 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 mineralization types (e.g. submarine nodules) may warrant disclosure of detailed information.Sampling has been conducted on drill core (half core for >90% and quarter core for check samples), grab samples (field samples of in-situ bedrock and boulders; including duplicate samples), trench samples (rock chips, including duplicates) and soil samples (including duplicate samples).
Locations of field samples were obtained by using a GPS, generally to an accuracy of within 5 metres. Drill hole and trench locations have been confirmed to <1 metre using a differential GPS.
Samples locations have also been verified by plotting locations on the high-resolution Lidar mapsDrill core is marked for cutting and cut using an automated diamond saw used by Company staff in Kilmore.
Samples are bagged at the core saw and transported to the Bendigo On Site Laboratory for assay.
At On Site samples are crushed using a jaw crusher combined with a rotary splitter and a 1 kg split is separated for pulverizing (LM5) and assay.Standard fire assay techniques are used for gold assay on a 30 g charge by experienced staff (used to dealing with high sulfide and stibnite-rich charges). On Site gold method by fire assay code PE01S.Screen fire assay is used to understand gold grain-size distribution where coarse gold is evident.ICP-OES is used to analyse the aqua regia digested pulp for an additional 12 elements (method BM011) and over-range antimony is measured using flame AAS (method known as B050).Soil samples were sieved in the field and an 80 mesh sample bagged and transported to ALS Global laboratories in Brisbane for super-low level gold analysis on a 50 g samples by method ST44 (using aqua regia and ICP-MS).Grab and rock chip samples are generally submitted to On Site Laboratories for standard fire assay and 12 element ICP-OES as described above.Drilling techniquesDrill 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.).HQ or NQ diameter diamond drill core, oriented using Boart Longyear TruCore orientation tool with the orientation line marked on the base of the drill core by the driller/offsider.
A standard 3 metre core barrel has been found to be most effective in both the hard and soft rocks in the project.Drill sample recoveryMethod of recording and assessing core and chip sample recoveries and results assessed.Measures taken to maximise sample recovery and ensure representative nature of the samples.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.Core recoveries were maximised using HQ or NQ diamond drill core with careful control over water pressure to maintain soft-rock integrity and prevent loss of fines from soft drill core. Recoveries are determined on a metre-by-metre basis in the core shed using a tape measure against marked up drill core checking against driller’s core blocks.Plots of grade versus recovery and RQD (described below) show no trends relating to loss of drill core, or fines.LoggingWhether 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.Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography.The total length and percentage of the relevant intersections logged.Geotechnical logging of the drill core takes place on racks in the company core shed.
Core orientations marked at the drill rig are checked for consistency, and base of core orientation lines are marked on core where two or more orientations match within 10 degrees.
Core recoveries are measured for each metre
RQD measurements (cumulative quantity of core sticks > 10 cm in a metre) are made on a metre-by-metre basis.Each tray of drill core is photographed (wet and dry) after it is fully marked up for sampling and cutting.The ½ core cutting line is placed approximately 10 degrees above the orientation line so the orientation line is retained in the core tray for future work.Geological logging of drill core includes the following parameters:
Rock types, lithology
Alteration
Structural information (orientations of veins, bedding, fractures using standard alpha-beta measurements from orientation line; or, in the case of un-oriented parts of the core, the alpha angles are measured)
Veining (quartz, carbonate, stibnite)
Key minerals (visible under hand lens, e.g. gold, stibnite)100% of drill core is logged for all components described above into the company MX logging database.Logging is fully quantitative, although the description of lithology and alteration relies on visible observations by trained geologists.Each tray of drill core is photographed (wet and dry) after it is fully marked up for sampling and cutting.Logging is considered to be at an appropriate quantitative standard to use in future studies.Sub-sampling techniques and sample preparationIf core, whether cut or sawn and whether quarter, half or all core taken.If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry.For all sample types, the nature, quality and appropriateness of the sample preparation technique.Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples.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.Whether sample sizes are appropriate to the grain size of the material being sampled.Drill core is typically half-core sampled using an Almonte core saw. The drill core orientation line is retained.Quarter core is used when taking sampling duplicates (termed FDUP in the database).Sampling representivity is maximised by always taking the same side of the drill core (whenever oriented), and consistently drawing a cut line on the core where orientation is not possible. The field technician draws these lines.Sample sizes are maximised for coarse gold by using half core, and using quarter core and half core splits (laboratory duplicates) allows an estimation of nugget effect.In mineralized rock the company uses approximately 10% of ¼ core duplicates, certified reference materials (suitable OREAS materials), laboratory sample duplicates and instrument repeats.In the soil sampling program duplicates were obtained every 20th sample and the laboratory inserted low-level gold standards regularly into the sample flow.Quality of assay data and laboratory testsThe nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total.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.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.The fire assay technique for gold used by On Site is a globally recognised method, and over-range follow-ups including gravimetric finish and screen fire assay are standard. Of significance at the On Site laboratory is the presence of fire assay personnel who are experienced in dealing with high sulfide charges (especially those with high stibnite contents) – this substantially reduces the risk of in accurate reporting in complex sulfide-gold charges.The ICP-OES technique is a standard analytical technique for assessing elemental concentrations. The digest used (aqua regia) is excellent for the dissolution of sulfides (in this case generally stibnite, pyrite and trace arsenopyrite), but other silicate-hosted elements, in particular vanadium (V), may only be partially dissolved. These silicate-hosted elements are not important in the determination of the quantity of gold, antimony, arsenic or sulphur.A portable XRF has been used in a qualitative manner on drill core to ensure appropriate core samples have been taken (no pXRF data are reported or included in the MX database).Acceptable levels of accuracy and precision have been established using the following methods
¼ duplicates – half core is split into quarters and given separate sample numbers (commonly in mineralized core) – low to medium gold grades indicate strong correlation, dropping as the gold grade increases over 40 g/t Au.
Blanks – blanks are inserted after visible gold and in strongly mineralized rocks to confirm that the crushing and pulping are not affected by gold smearing onto the crusher and LM5 swing mill surfaces. Results are excellent, generally below detection limit and a single sample at 0.03 g/t Au.
Certified Reference Materials – OREAS CRMs have been used throughout the project including blanks, low (<1 g/t Au), medium (up to 5 g/t Au) and high-grade gold samples (> 5 g/t Au). Results are automatically checked on data import into the MX database to fall within 2 standard deviations of the expected value.
Laboratory splits – On Site conducts splits of both coarse crush and pulp duplicates as quality control and reports all data. In particular, high Au samples have the most repeats.
Laboratory CRMs – On Site regularly inserts their own CRM materials into the process flow and reports all data
Laboratory precision – duplicate measurements of solutions (both Au from fire assay and other elements from the aqua regia digests) are made regularly by the laboratory and reported.Accuracy and precision have been determined carefully by using the sampling and measurement techniques described above during the sampling (accuracy) and laboratory (accuracy and precision) stages of the analysis.Soil sample company duplicates and laboratory certified reference materials all fall within expected ranges.Verification of sampling and assayingThe verification of significant intersections by either independent or alternative company personnel.The use of twinned holes.Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols.Discuss any adjustment to assay data.The Independent Geologist has visited Sunday Creek drill sites and inspected drill core held at the Kilmore core shed.Visual inspection of drill intersections matches both the geological descriptions in the database and the expected assay data (for example, gold and stibnite visible in drill core is matched by high Au and Sb results in assays).In addition, on receipt of results Company geologists assess the gold, antimony and arsenic results to verify that the intersections returned expected data.The electronic data storage in the MX database is of a high standard. Primary logging data are entered directly by the geologists and field technicians and the assay data are electronically matched against sample number on return from the laboratory.Certified reference materials, ¼ core field duplicates (FDUP), laboratory splits and duplicates and instrument repeats are all recorded in the database.Exports of data include all primary data, from hole SDDSC077B onwards after discussion with SRK Consulting. Prior to this gold was averaged across primary, field and lab duplicates.Adjustments to assay data are recorded by MX, and none are present (or required).Twinned drill holes are not available at this stage of the project.Location of data pointsAccuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation.Specification of the grid system used.Quality and adequacy of topographic control.Differential GPS used to locate drill collars, trenches and some workingsStandard GPS for some field locations (grab and soils samples), verified against Lidar data.The grid system used throughout is Geocentric datum of Australia 1994; Map Grid Zone 55 (GDA94_Z55), also referred to as ELSG 28355.Topographic control is excellent owing to sub 10 cm accuracy from Lidar data.Data spacing and distributionData spacing for reporting of Exploration Results.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.Whether sample compositing has been applied.The data spacing is suitable for reporting of exploration results – evidence for this is based on the improving predictability of high-grade gold-antimony intersections.At this time, the data spacing and distribution are not sufficient for the reporting of Mineral Resource Estimates. This however may change as knowledge of grade controls increase with future drill programs.Samples have been composited to a 1 g/t AuEq over 2.0 m width for lower grades and 5 g/t AuEq over 1.0 m width for higher grades in table 3. All individual assays above 0.1 g/t AuEq have been reported with no compositing in table 4. Orientation of data in relation to geological structureWhether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type.If the relationship between the drilling orientation and the orientation of key mineralized structures is considered to have introduced a sampling bias, this should be assessed and reported if material.The true thickness of the mineralized intervals reported are interpreted to be approximately 40% of the sampled thickness. Drilling is oriented in an optimum direction when considering the combination of host rock orientation and apparent vein control on gold and antimony grade.
The steep nature of some of the veins may give increases in apparent thickness of some intersections, but more drilling is required to quantify.A sampling bias is not evident from the data collected to date (drill holes cut across mineralized structures at a moderate angle).Sample securityThe measures taken to ensure sample security.Drill core is delivered to the Kilmore core logging shed by either the drill contractor or company field staff. Samples are marked up and cut by company staff at the Kilmore core shed, in an automated diamond saw and bagged before loaded onto strapped secured pallets and trucked by company staff to Bendigo for submission to the laboratory. There is no evidence in any stage of the process, or in the data for any sample security issues.Audits or reviewsThe results of any audits or reviews of sampling techniques and data.Continuous monitoring of CRM results, blanks and duplicates is undertaken by geologists and the company data geologist. Mr Michael Hudson for SXG has the orientation, logging and assay data.

CriteriaJORC Code explanationCommentaryMineral tenement
and land tenure
statusType, 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 security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area.The Sunday Creek Goldfield, containing the Clonbinane Project, is covered by the Retention Licence RL 6040 and is surrounded by Exploration Licence EL6163 and Exploration Licence EL7232. All the licences are 100% held by Clonbinane Goldfield Pty Ltd, a wholly owned subsidiary company of Southern Cross Gold Ltd.Exploration done by
other parties Acknowledgment and appraisal of exploration by other parties.The main historical prospect within the Sunday Creek project is the Clonbinane prospect, a high level orogenic (or epizonal) Fosterville-style deposit. Small scale mining has been undertaken in the project area since the 1880s continuing through to the early 1900s. Historical production occurred with multiple small shafts and alluvial workings across the Clonbinane Goldfield permits. Production of note occurred at the Clonbinane area with total production being reported as 41,000 oz gold at a grade of 33 g/t gold (Leggo and Holdsworth, 2013)Work in and nearby to the Sunday Creek Project area by previous explorers typically focused on finding bulk, shallow deposits. Beadell Resources were the first to drill deeper targets and Southern Cross have continued their work in the Sunday Creek Project area. EL54 – Eastern Prospectors Pty LtdRock chip sampling around Christina, Apollo and Golden Dyke mines.
Rock chip sampling down the Christina mine shaft. Resistivity survey over the Golden Dyke. Five diamond drill holes around Christina, two of which have assays.ELs 872 & 975 – CRA Exploration Pty LtdExploration focused on finding low grade, high tonnage deposits. The tenements were relinquished after the area was found to be prospective but not economic.
Stream sediment samples around the Golden Dyke and Reedy Creek areas. Results were better around the Golden Dyke. 45 dump samples around Golden Dyke old workings showed good correlation between gold, arsenic and antimony.
Soil samples over the Golden Dyke to define boundaries of dyke and mineralization. Two costeans parallel to the Golden Dyke targeting soil anomalies. Costeans since rehabilitated by SXG.ELs 827 & 1520 – BHP Minerals LtdExploration targeting open cut gold mineralization peripheral to SXG tenements.ELs 1534, 1603 & 3129 – Ausminde Holdings Pty LtdTargeting shallow, low grade gold. Trenching around the Golden Dyke prospect and results interpreted along with CRAs costeans. 29 RC/Aircore holes totalling 959 m sunk into the Apollo, Rising Sun and Golden Dyke target areas.
ELs 4460 & 4987 – Beadell Resources LtdELs 4460 & 4987 – Beadell Resources LtdELs 4460 and 4497 were granted to Beadell Resources in November 2007. Beadell successfully drilled 30 RC holes, including second diamond tail holes in the Golden Dyke/Apollo target areas.Both tenements were 100% acquired by Auminco Goldfields Pty Ltd in late 2012 and combined into one tenement EL4987. Nagambie Resources Ltd purchased Auminco Goldfields in July 2014. EL4987 expired late 2015, during which time Nagambie Resources applied for a retention licence (RL6040) covering three square kilometres over the Sunday Creek Goldfield. RL6040 was granted July 2017.Clonbinane Gold Field Pty Ltd was purchased by Mawson Gold Ltd in February 2020.Mawson drilled 30 holes for 6,928 m and made the first discoveries to depth.Geology Deposit type, geological setting and style ofmineralization.Refer to the description in the main body of the release.Drill hole Information A summary of all information material to the understanding of the exploration results including a tabulation of the followinginformation 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 collardip and azimuth of the holedown hole length and interception depth hole length.If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.Refer to appendicesData aggregation methodsIn 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.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.The assumptions used for any reporting of metal equivalent values should be clearly stated.See “Further Information” and “Metal Equivalent Calculation” in main text of press release.Relationship
between
mineralization
widths and
intercept lengthsThese relationships are particularly important in the reporting of Exploration Results.If the geometry of the mineralization 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 holelength, true width not known’).See reporting of true widths in the body of the press release.DiagramsAppropriate 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.The results of the diamond drilling are displayed in the figures in the announcement.Balanced reportingWhere 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.All results above 0.1 g/t Au have been tabulated in this announcement. The results are considered representative with no intended bias.Core loss, where material, is disclosed in tabulated drill intersections.Other substantive exploration dataOther 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.Previously reported diamond drill results are displayed in plans, cross sections and long sections and discussed in the text and in the Competent Person’s statement.Preliminary testing (AMML Report 1801-1) has demonstrated the viability of recovering gold and antimony values to high value products by industry standard processing methods.The program was completed by AMML, an established mineral and metallurgical testing laboratory specialising in flotation, hydrometallurgy, gravity and comminution testwork at their testing facilities in Gosford, NSW. The program was supervised by Craig Brown of Resources Engineering & Management, who was engaged to develop plans for initial sighter flotation testing of samples from drilling of the Sunday Creek deposit.Two quarter core intercepts were selected for metallurgical test work (Table 1). A split of each was subjected to assay analysis. The table below shows samples selected for metallurgical test work:Sample LocationSample NameWeight (kg)Drill holefrom (m)to (m)Length (m)Au ppmSb%As%Rising SunRS0122.8MDDSC025275.9289.313.43.181.060.223ApolloAP0116.6SDDSC031220.4229.99.54.890.4430.538

 

The metallurgical characterization test work included:Diagnostic LeachWELL testing.Gravity recovery by Knelson concentrator and hand panning.Timed flotation of combined gravity tails.Rougher-Cleaner flotation (without gravity separation), with sizing of products, to produce samples for mineralogical investigation.Mineral elemental concentrations and gold deportment was investigated using Laser Ablation examination by University of Tasmania. QXRD Mineralogical assessment were used to estimate mineral contents for the test products, and, from this, to assess performance in terms of minerals as well as elements, including contributions to gold deportment. For both test samples, observations and calculations indicated a high proportion of native (‘free’) gold: 84.0% in RS01 and 82.1% in AP01.Samples of size fractions of the three sulfide and gold containing flotation products from the Rougher-Cleaner test series were sent to MODA Microscopy for optical mineralogical assessment. Key observations were:The highest gold grade samples from each test series found multiple grains of visible gold which were generally liberated, with minor association with stibnite (antimony sulfide).Stibnite was highly liberated and was very ‘clean’ – 71.7% Sb, 28.3% S.Arsenopyrite was also highly liberated indicating potential for separation.Pyrite was largely free but exhibited some association with gangue minerals.Further workThe 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 Company drilled 30,000 m in 2023 and plans to continue drilling with 6 diamond drill rigs. The Company has stated it will drill 60,000 m from 2024 to Q4 2025. The company remains in an exploration stage to expand the mineralization along strike and to depth.See diagrams in presentation which highlight current and future drill plans.
