Mawson s Subsidiary SXG Reports Nine Holes from Sunday Creek Four > 100 G/T AuEq X Metre (Cumulative) Demonstrating Continuity and Predictability. New Vein Discovery

Highlights:

• Release of data from nine drillholes (SDDSC094A, 96, 98-104) that further enhance confidence and demonstrate continuity to near surface levels within the Rising Sun area. Notably, four of nine holes reported contain downhole cumulative intervals of > 100 g/t AuEq x metres.
• SDDSC094A was drilled through the upper zone of Rising Sun, from the hanging wall position and at a high angle to mineralized vein sets. The hole traversed four high-grade vein sets (Figures 1 and 2) including the discovery of one new vein set. Selected highlights include:
  • 2.0 m @ 5.6 g/t AuEq (5.5 g/t Au, 0.1% Sb) from 144.0 m

  • 2.6 m @ 10.1 g/t AuEq (9.3 g/t Au, 0.5% Sb) from 338.2 m

SDDSC098 drilled 25 m to 60 m below SDDSC094 also traversed four high-grade vein sets, highlights include:

Mawson owns 93,750,000 shares of SXG (51%), valuing its stake at A$107.3 million (C$93.8 million) based on SXG's closing price on February 8, 2024 AEST.

Michael Hudson, Mawson Interim CEO and Executive Chairman, states: "These holes provide the critical elements to drill out a mineralized body as we keep on demonstrating continuity and predictability of gold-antimony mineralization. Completed as drill fans starting at the upper Rising Sun area and going to depth, they fill in large gaps in an up- and down-dip sense as well as testing the strike extension of the mineralized vein sets. They increase our confidence in the geological model and demonstrate the continuity that supports the <2.0 coefficient of variation of our assay data within modelled veins that our geostatistics provides."

Drill Hole Discussion

The holes reported can be separated into two areas: Rising Sun Upper and Rising Sun Lower.

Rising Sun Upper

SDDSC094A (cumulative 199 g/t AuEq x m @ 2 m @ 1g/t AuEq lower cut) and SDDSC098 (cumulative 134 g/t AuEq x m) showed continuity of high grades to near surface levels (from 70 m vertically below surface).

The two drill holes intersected four mineralized vein sets each which provided key infill points and assist in the definition of a new vein set at Rising Sun, named RS35 (1.3 m @ 22.1 g/t AuEq (13.0 g/t Au, 5.8% Sb) from 277.3 m in SDDSC094A and 1.5 m @ 1.1 g/t AuEq (1.1 g/t Au, 0.0% Sb) from 241.1 m in SDDSC098.

• 2.6 m @ 10.1 g/t AuEq (9.3 g/t Au, 0.5% Sb) from 338.2 m, including:

  • 0.3 m @ 20.6 g/t AuEq (3.0 g/t Au, 11.2% Sb) from 154.3 m

• 5.5 m @ 1.3 g/t AuEq (1.2 g/t Au, 0.0% Sb) from 211.0 m

SDDSC096 (cumulative 13 g/t AuEq x m) with a highlight of 0.5 m @ 21.8 g/t AuEq (21.8 g/t Au, 0.0% Sb) from 120.8 m and SDDSC099 (cumulative 10 g/t AuEq x m) were drilled at too high an intersection angle across the mineralized host horizon, and therefore passed from the hangingwall to the footwall of the mineralized host too rapidly and remained in unaltered sediment until end of hole (Figures 1 and 2).

SDDSC101 and SDDSC103 were drilled 20 m to 30 m north of the host horizon and did not contain mineralization. They define the northern mineralization boundary in the western portion of Rising Sun Upper and provide further structural information in the hanging wall (Figures 1 and 2).

The hole was drilled 80 m to 180 m down dip from SDDSC077B and 7 m to 160 m up dip from SDDSC082 (Figure 3) and provides critical infill points to confirm continuity of eleven vein sets over 430 vertical m.

• 4.0 m @ 1.8 g/t AuEq (1.7 g/t Au, 0.0% Sb) from 911.0 m

SDDSC102 (cumulative 35 g/t AuEq x m) and SDDSC104 (cumulative 115 g/t AuEq x m) drilled from the southern margin of the host sequence, intersected the host lower in each hole and five and four vein sets respectively.

Pending Results and Update

Ten holes (SDDSC0105 - 107, 108A, 109-112, 112W1, 114) are currently being processed and analyzed, with three holes (SDDSC113, 115A, 116) currently in progress (Figures 1-2). Southern Cross Gold has stated that it anticipates drilling an additional 19,000 m by April 2024.

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 1-5 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 50% to 60% of the sampled thickness for other reported holes. Lower grades were cut at 1.0 g/t Au 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 otherwise¹ 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: = ( / ) + 1.58 (%).

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 = ( / ) + 1.58 (%) is appropriate to use for the initial exploration targeting of gold-antimony mineralization at Sunday Creek.
