Highlights:
• Release of assay data from two drillholes (SDDSC106 and 109) show that the Apollo Deep area is becoming higher grade at depth (Figure 3).
• SDDSC106 drilled east to west successfully traversed 6 high-grade vein sets over a 200 m interval. The hole contains eight intervals > 15 g/t Au (up to 59.9 g/t Au) and eight intervals of >5 % Sb (up to 34.5 % Sb). Selected highlights include:
o 34.9 m @ 6.1 g/t AuEq (4.0 g/t Au, 1.3% Sb) from 364.0 m
o 6.0 m @ 5.5 g/t AuEq (4.4 g/t Au, 0.7% Sb) from 412.0 m
o 0.8 m @ 61.6 g/t AuEq (30.9 g/t Au, 19.5% Sb) from 535.0 m
• SDDSC109 was drilled parallel to and 70 m to 120 m up-dip of SDDSC106. It traversed seven vein sets in total. This drillhole contains eight intervals >15 g/t Au (up to 99.8 g/t Au) and five intervals >5% Sb (up to 33.8 % Sb). Selected highlights include:
o 6.8 m @ 5.5 g/t AuEq (4.4 g/t Au, 0.7% Sb) from 345.2 m
o 9.2 m @ 10.3 g/t AuEq (7.0 g/t Au, 2.1% Sb) from 456.8 m, including:
▪ 2.8 m @ 32.3 g/t AuEq (21.4 g/t Au, 6.9% Sb) from 459.0 m
• Eight drillholes at Sunday Creek at are being processed and analysed, with three holes in progress (Figures 1 and 2).
• Mawson owns 93,750,000 shares of SXG (51%), valuing its stake at A$118.6 million (C$105.2 million) based on SXG’s closing price on February 20, 2024 AEST.

Michael Hudson, Mawson Interim CEO and Executive Chairman, states: “Since SXG was listed less than 20 months ago, our team has routinely drilled to depth at Sunday Creek to test the well understood geological opportunity to find extremely high grade, “Cinderella Zones”, that form at depth in the Victorian epizonal systems. Over the last 12 months the Rising Sun area has demonstrated spectacular results at depth and now it’s Apollo’s turn to show the same trend with eight intervals >15 g/t Au (up to 59.9 g/t Au) and eight intervals of >5% Sb (up to 34.5% Sb) including 34.9 m @ 6.1 g/t AuEq from 364.0 m (Figure 3). These holes immediately increase the volume and grade of our initial exploration target published in January. With several drillholes from Apollo Deep in the assay lab we look forward to seeing what else can develop at depth in Apollo.”

Drill Hole Discussion

SDDSC105 was terminated early due to it deviating too far from target. The hole intercepted near-miss alteration including sericite-pyrite +/- carbonate alteration associated with mineralisation at the top of the hole over a 90 m zone from (197 m to 287 m). Highlights included 1.0 m @ 1.7 g/t AuEq (1.7 g/t Au, 0.0% Sb) from 221.0 m and 0.4 m @ 1.7 g/t AuEq (1.7 g/t Au, 0.0% Sb) from 225.0 m.

SDDSC106 was drilled east to west through into the Apollo Deep area and successfully traversed 6 high-grade vein sets over a 200 m interval. SDDSC106 contains eight intervals >15 g/t Au (up to 59.9 g/t Au) and eight intervals of >5 % Sb (up to 34.5% Sb). This hole confirms the mineral system is increasing in grade at depth (Figure 3) as it does across the Sunday Creek field. This observation is considered extremely promising. Several drillholes to report (SDDSC108A, 112W1 and 116) will continue to test the trend of higher grades and thickness at depth at Apollo.

Pending Results and Update

Further Information
Further discussion and analysis of the Sunday Creek project by Southern Cross Gold is available on the SXG website at www.southerncrossgold.com.au.

No upper gold grade cut is applied in the averaging and intervals are reported as drill thickness. During future Mineral Resource studies, the requirement for assay top cutting will be assessed.

Figures 1-4 show project location, plan, longitudinal and cross-sectional views of drill results reported here and Tables 1–3 provide collar and assay data. The true thickness of the mineralised intervals reported are interpreted to be approximately 60% to 70% of the sampled thickness. 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 Au lower cutoff over a maximum of 1 m width, unless otherwise stated (0.3 g/t Au lower cutoff over a maximum width of 3 m).

Technical Background and Qualified Person
The Qualified Person, Michael Hudson, Executive Chairman and a director of Mawson Gold, and a Fellow of the Australasian Institute of Mining and Metallurgy, has 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 gram 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 content, blanks within interpreted mineralized rock and quarter core duplicates. In addition, On Site inserts blanks and standards into the analytical process.

MAW 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.

SXG considers that it is appropriate to adopt the same gold equivalent variables as Mandalay Resources Ltd in its Mandalay Technical Report, 2022 dated 25 March 2022. The gold equivalence formula used by Mandalay Resources was calculated using recoveries achieved at the Costerfield Property Brunswick Processing Plant during 2020, using a gold price of US$1,700 per ounce, an antimony price of US$8,500 per tonne and 2021 total year metal recoveries of 93% for gold and 95% for antimony, and is as follows:

AuÄq= Au (g/t) + 1,58 × Sb (%).

Based on the latest Costerfield calculation and given the similar geological styles and historic toll treatment of Sunday Creek mineralization at Costerfield, SXG considers that a 𝐴𝑢𝐸𝑞 = 𝐴𝑢 (𝑔/𝑡) + 1.58 × 𝑆𝑏 (%) is appropriate to use for the initial exploration targeting of gold-antimony mineralization at Sunday Creek.
