Southern Cross Gold reinforces continuity in Rising Sun

Five Key Points

1. Strike Continuity Confirmed: SDDSC169AW1 intercepted 0.5 m @ 342.2 g/t AuEq just 12 m along strike from SDDSC118’s previously reported 0.7 m @ 604.0 g/t AuEq intersection, demonstrating highgrade continuity within the RS15 vein

2. Broad Mineralized Zones Host Multiple High-Grade Shoots: SDDSC178W1 returned 18.0 m @ 3.7 g/t AuEq containing four distinct higher-grade intervals, while SDDSC169AW1 delivered 5.9 m @ 4.6 g/t AuEq and 6.1 m @ 3.4 g/t AuEq, demonstrating both scale and grade

3. Stacked Vein Architecture Confirmed: Successfully intercepted seven distinct mineralized vein sets in SDDSC169AW1 and nine vein sets in SDDSC178W1 across vertical intervals exceeding 160 m,
confirming the multi-level nature of the Rising Sun system

4. High Antimony Grades: Three individual assays exceeded 40% Sb (approaching pure stibnite at approximately 71% Sb), including 43.8 % Sb and 42.1 % Sb, reinforcing Sunday Creek’s strategic importance as a Western World antimony source

5. Project Milestone: Results bring the total to 70 intersections >100 g/t AuEq x m and 74 intersections >50 to 100 g/t AuEq x m across Sunday Creek, establishing it as one of the highest-grade gold projects globally

Michael Hudson, President & CEO, states: "Sunday Creek again delivers grade and scale. While we’ve established the continuity in the up-and-down orientation of the vein sets through extensive drilling, it’s now, with this more recent focus on along-strike drilling, that we’re seeing further lateral grade continuity confirmed. SDDSC169AW1’s intersection of 0.5 m @ 342 g/t AuEq being just 12 m along strike from our previous 0.7 m @ 604 g/t AuEq intersection in the RS15 vein reconfirms that the high grades extend consistently in multiple directions.

"What makes Sunday Creek unique isn’t just the high grades – it’s the combination of high grades with broader mineralized widths. SDDSC178W1’s 18 m @ 3.7 g/t AuEq interval exemplifies this perfectly, containing four distinct higher-grade vein sets within a single broad envelope. This demonstrates how stacked vein sets can create substantially wider zones that are potentially mineable. Additionally, with three zones exceeding 40% Sb alongside these high-grade, broad gold-rich intervals, Sunday Creek showcases a rare combination of grade in two attractive commodities and significant width.

"This announcement at Rising Sun, along with previous announcements over the last 2 months at Apollo East, Golden Dyke and Christina, demonstrates significant progress with resource drilling and confidence in the continuity of mineralization, as well as extending the Exploration Target. With 70 drill intersections now exceeding 100 gram-metre AuEq across the project, and our successful use of wedge technology enabling precise targeting of these vein sets, Rising Sun, as one of five bodies across Sunday Creek, continues to deliver on scale, grade, and continuity. This is exceptional by any global standard."

FOR THOSE WHO LIKE THE DETAILS

Key Take Aways

SDDSC169AW1 – Confirming RS15 Lateral Continuity:

• Intercepted seven distinct vein sets using wedge technology after initial hole deviation

• 0.5 m @ 342.2 g/t AuEq (335.5 g/t Au, 2.8% Sb) from 615.7 m, located just 12 m along strike from previous 0.7 m @ 604 g/t AuEq intersection from 555.7 m, proving exceptional lateral grade continuity in RS15 vein. Individual assay of 0.3 m @ 592.0 g/t Au from 616.0 m represents some of the highest gold grades at Rising Sun

• 5.9 m @ 4.6 g/t AuEq from 550.3 m includes 1.4 m @ 12.6 g/t AuEq, demonstrating broader mineralization enveloping high-grade cores

• Four separate mineralized intervals from 550 m to 700 m depth demonstrate stacked vein set architecture across 150 m vertical extent

SDDSC178W1 – Multiple High-Grade Vein Sets with Exceptional Antimony:

• Successfully intercepted nine vein sets after wedging from deviated parent hole, with mineralization intersected from 434 m to 593 m which shows excellent vertical continuity across 160 m

• 18.0 m @ 3.7 g/t AuEq from 574.8 m represents the broadest mineralized interval in these results, containing four distinct higher-grade zones including 0.6 m @ 17.7 g/t AuEq and 1.5 m @ 9.0 g/t AuEq

• Record antimony grades with three assays >40 % Sb, including 0.13 m @ 43.8% Sb from 589.8
m and 0.13 m @ 42.1% Sb 524.7 m (approaching pure stibnite at approx. 71 % Sb)

• 1.2 m @ 13.9 g/t AuEq 524.0 m includes 0.1 m @ 125.9 g/t AuEq combining both high gold (25.3 g/t) and antimony (42.1%), demonstrating co-precipitation of both metals

Technical Achievement:
• Both holes utilized precise wedge technology to achieve optimal vein intersections after initial deviations
• Results bring project totals to 70 intersections >100 g/t AuEq x m and 74 intersections >50 to 100 g/t AuEq x m

Drill Hole Discussion
Results are reported from five diamond drill holes at the Rising Sun prospect:
• SDDSC169, SDDSC169A, and SDDSC169AW1
• SDDSC178 and SDDSC178W1

SDDSC169 Series: The original hole (SDDSC169) was abandoned early due to excessive deviation. A wedge hole (SDDSC169A) was drilled to maintain the planned infill spacing. This ultimately led to the successful third wedge (SDDSC169AW1).

SDDSC178 Series: SDDSC178 was drilled west to east, running sub-parallel to the main dyke and alteration zone but at a high angle to the mineralization and vein orientations. When the hole deviated too far from the target zone, it was abandoned. A wedge hole (SDDSC178W1) was then completed to achieve the planned infill spacing, resulting in successful intersections.

SDDSC169 SERIES

SDDSC169AW1 was drilled in a west to east orientation, sub-parallel to the main dyke and alteration package and at a high angle to mineralization and vein orientations.

SDDSC169AW1 intercepted seven vein sets in the Rising Sun system and confirmed exceptional high-grade continuity along strike within the RS15 vein structure (Figure 6). The hole returned 0.5 m @ 342.2 g/t AuEq (335.5 g/t Au, 2.8% Sb) from 615.7 m, located just 12 m along strike from SDDSC118 which previously reported 0.7 m @ 604.0 g/t AuEq (604.0 g/t Au, 0.0% Sb) from 555.7 m (reported June 13, 2024). The continuity of extremely high-grade mineralization confirms the robust nature of the RS15 vein system.

Drill hole highlights from SDDSC169AW1 include:
• 5.9 m @ 4.6 g/t AuEq (3.6 g/t Au, 0.4% Sb) from 550.3 m, including:
o 1.4 m @ 12.6 g/t AuEq (9.3 g/t Au, 1.4% Sb) from 554.8 m

• 3.4 m @ 1.4 g/t AuEq (1.3 g/t Au, 0.1% Sb) from 572.0 m

• 0.5 m @ 342.2 g/t AuEq (335.5 g/t Au, 2.8% Sb) from 615.73 m, including:
o 0.3 m @ 603.3 g/t AuEq (592.0 g/t Au, 4.7% Sb) from 615.98 m

• 2.8 m @ 2.0 g/t AuEq (0.8 g/t Au, 0.5% Sb) from 632.06 m

• 8.9 m @ 1.5 g/t AuEq (0.6 g/t Au, 0.4% Sb) from 678.78 m

• 6.1 m @ 3.4 g/t AuEq (3.0 g/t Au, 0.2% Sb) from 693.87 m, including:
o 0.1 m @ 117.4 g/t AuEq (116.0 g/t Au, 0.6% Sb) from 699.82 m

• 5.7 m @ 0.9 g/t AuEq (0.5 g/t Au, 0.2% Sb) from 704.27 m

• 1.2 m @ 5.2 g/t AuEq (3.9 g/t Au, 0.6% Sb) from 719.61 m

The intersection of multiple mineralized zones across significant intervals, combined with the high-grade cores, demonstrates the potential for both selective high-grade mining and bulk mining scenarios at Rising Sun.

SDDSC178 SERIES

SDDSC178W1 intercepted nine vein sets in the Rising Sun system, demonstrating the extensive stacked nature of mineralization. Remarkably, three individual assays reported antimony grades exceeding 40%, including 0.13 m at 43.8 % Sb and 3.15 g/t Au from 589.84 m and 0.13 m at 42.1 % Sb and 25.3 g/t Au from 524.66 m. These extraordinary antimony grades approach theoretical pure stibnite (Sb₂S₃ = ~71% Sb) and highlight Rising Sun’s potential to supply critical antimony to Western markets.

Drill hole highlights from SDDSC178W1 include:

• 0.6 m @ 51.5 g/t AuEq (30.2 g/t Au, 8.9% Sb) from 434.3 m

• 0.5 m @ 8.0 g/t AuEq (6.5 g/t Au, 0.6% Sb) from 526.99 m

• 1.2 m @ 13.9 g/t AuEq (2.9 g/t Au, 4.6% Sb) from 523.99 m, including:
o 0.1 m @ 125.9 g/t AuEq (25.3 g/t Au, 42.1% Sb) from 524.66 m

• 0.4 m @ 12.2 g/t AuEq (8.4 g/t Au, 1.6% Sb) from 528.67 m

• 1.0 m @ 5.3 g/t AuEq (4.3 g/t Au, 0.4% Sb) from 540.62 m

• 2.6 m @ 1.1 g/t AuEq (0.8 g/t Au, 0.1% Sb) from 542.96 m

• 1.1 m @ 5.4 g/t AuEq (4.9 g/t Au, 0.2% Sb) from 567.91 m

• 18.0 m @ 3.7 g/t AuEq (1.6 g/t Au, 0.9% Sb) from 574.75 m, including:
o 0.6 m @ 17.7 g/t AuEq (14.9 g/t Au, 1.2% Sb) from 580.0 m
o 1.5 m @ 9.0 g/t AuEq (4.1 g/t Au, 2.1% Sb) from 582.17 m
o 0.2 m @ 51.4 g/t AuEq (3.6 g/t Au, 20.0% Sb) from 584.69 m
o 1.3 m @ 14.1 g/t AuEq (2.0 g/t Au, 5.1% Sb) from 588.85 m

• 2.4 m @ 1.6 g/t AuEq (0.6 g/t Au, 0.4% Sb) from 596.0 m

• 5.8 m @ 1.2 g/t AuEq (1.1 g/t Au, 0.0% Sb) from 670.0 m

The 18 m mineralized envelope containing multiple high-grade cores exemplifies Sunday Creek’s characteristic mineralization style, where broader zones of economic mineralization host spectacular highgrade shoots.

Pending Results and Program Update

Results are pending from 32 holes currently being processed and analyzed including nine holes that are actively being drilled and four abandoned holes, with nine rigs actively drilling. The Company continues its 200,000 m drill program through Q1 2027.

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. SXGC 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.

Cumulatively, 220 drill holes for 97,553.07 m have been reported from Sunday Creek since late 2020. This amount includes five holes for 929 m that have been drilled for geotechnical purposes and 19 holes for 2,120.27 m that 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 Seventy (70) >100 g/t AuEq x m and seventy-four (74) >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 high-grade 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 have been more intensively drill tested (Rising Sun to Apollo). At least 83 ‘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 (Figures 1 to 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 SXGC website. These data, along with an interview on these results with Michael Hudson, President & CEO, 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 6 show project location, plan, longitudinal views and analysis 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 60% to 90% 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.

Critical Metal Epizonal Gold-Antimony Deposits

Sunday Creek 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 (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.

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

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

About Southern Cross Gold Consolidated Ltd. (TSX:SXGC) (ASX:SX2) (OTCQX: SXGCF)

Southern Cross Gold Consolidated Ltd. (TSX: SXGC, ASX: SX2, OTCQX: SXGCF), controls the Sunday Creek Gold-Antimony Project located 60 km 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 70 intersections exceeding 100 g/t AuEq x m from just 97.5 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 approximately 20 % of the in-situ value alongside gold, meaning Importantly, Sunday Creek can be developed primarily based on gold economics, which reduces antimony-related risks while maintaining strategic supply potential. This has gained increased significance following China’s export restrictions on antimony, a critical metal for defense and semiconductor applications. Southern Cross’ inclusion in the US Defense Industrial Base Consortium (DIBC) and Australia’s AUKUS-related legislative changes position it as a potential key Western antimony supplier.

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 strong cash position, over 1,000 Ha of strategic freehold land ownership, and a large 200 km drill program planned through Q1 2027, SXGC is well-positioned to advance this globally significant goldantimony discovery in a tier-one jurisdiction.

NI 43-101 Technical Background and Qualified Person

Michael Hudson, President and CEO and Managing Director of SXGC, and a Fellow of the Australasian Institute of Mining and Metallurgy, and Mr Kenneth Bush, Exploration Manager of SXGC and a RPGeo (10315) of the Australian Institute of Geoscientists, are the Qualified Persons as defined by the NI 43-101. They have prepared, 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.

SXGC considers that both gold and antimony that are included in the gold equivalent calculation (“AuEq") have reasonable potential to be recovered and sold 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.

SXGC 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 × 𝑆𝑏 (%)

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