Vancouver, Canada — Mawson Gold Limited (“Mawson” or the “Company”) (TSX:MAW) (Frankfurt:MXR) (PINKSHEETS: MWSNF - https://www.commodity-tv.com/ondemand/companies/profil/mawson-gold-ltd/ ) announces the best hole drilled to date, SDDSC082, at SXG’s 100%-owned Sunday Creek Project in Victoria, Australia, a spectacularly wide and high grade intersection of gold-antimony mineralization of 331.5 m @ 6.8 g/t Au from 413.6 m (uncut) in a 180 m to 290 m (average 200 m) down dip extension of a previous drilled mineralized zone (Figure 5).
SDDSC082 contains the highest grades (up to 4,190 g/t Au) and includes three of the top five individual intersections at Sunday Creek: 13.1 m @ 91.7 g/t Au from 413.6 m, 68.5m @ 4.8 g/t Au from 506.3 m and 5.0 m @ 60.9 g/t Au from 588.0 m. Seven assayed intervals have >100 g/t Au (up to 4,190 g/t Au), 20 assayed intervals have >15 up to 100 g/t Au and seven intervals have >5% Sb (up to 24.3% Sb).
Sunday Creek is 100% owned by Southern Cross Gold (“SXG”), which is an ASX listed company owned 51% by Mawson. Four rigs continue to drill in the main drill area at Sunday Creek where 18 holes (SDDSC079, 83, 85-86, 88-99, 101, 103) are currently being geologically processed and chemically analyzed, and four holes (SDDSC0100, 102, 104, 105) are in drill progress (Figures 1-2).

Noora Ahola, Mawson Interim CEO, states: “Sunday Creek is proving the old adage correct that great projects keep getting better with further, targeted drilling. So it is with the release of SDDSC082 (331.5 m @ 6.8 g/t Au (uncut)) as the best hole, and the most significant, drilled so far at Sunday Creek. It is, on average, a 200 m down dip extension from SDDSC077B, SXG’s previous best hole, from only a little more than a month ago, and intersected 18 veins with super high grades (up to 4,190 g/t Au) intersected in a new vein, only 400 m vertically below the surface.
SXG has a highly targeted 19,000 m drill program at the Rising Sun and Apollo zones at Sunday Creek to April 2024 which leads us to believe we will see further outstanding drill results in the coming months.”
Results Discussion
Drill hole SDDSC082 331.5 m @ 7.1 g/t AuEq (6.8 g/t Au, 0.2 %Sb) from 413.6 m (uncut) was drilled as a 180 m to 230 m down dip extension from SDDSC077B in the upper parts of the mineralized system, and lower in SDDSC082 up to 290 m down dip from SDDSC050 (305 m @ 2.4 g/t AuEq, reported November 20, 2022). Mineralization in SDDSC082 extended from 331.5 m to 1,065.3 m down hole, for a total length of 733.8 m.
On a grade-thickness basis, SDDSC082 (cumulative 2,418 AuEq g/t x m) is the best hole drilled on the project to date and exceeded SDDSC077B (cumulative 2,272 AuEq g/t x m) and SDDSC050 (cumulative 852 AuEq g/t x m).
Drill hole SDDSC082 is a significant expansion of the mineralized footprint. The hole hit continuous mineralization that can be extended from surface to 500 m depth and also drilled the deepest mineralization on the project to 1 km vertical depth (0.6 m @ 20.0 g/t AuEq (16.4 g/t Au, 2.3 %Sb) from 1,064.5 m (Figures 1-3).
SDDSC082 traverses 18 individual high grade vein sets (Figures 1-3). Seven intervals contained >100 g/t Au (up to 4,190 g/t Au), 20 intervals have >15 g/t Au up to 100 g/t Au and 7 intervals have >5% Sb (up to 24.3% Sb). The hole was drilled parallel to the enveloping host breccia dyke but at a high angle to the predominant NW-SW high-grade vein trend. As the hole was relatively steeply drilled into the steep mineralised veins sets, the true thickness of the mineralised interval is interpreted to be approximately 40% to 50% of the sampled thickness.
The very highest-grade interval (0.2 m @ 4,190 g/t Au) was intersected in a previously undrilled vein on the undrilled western margin of the Rising Sun area (Figure 2). It appears to form blind below a bulge in the dyke breccia host and is open down dip. Development of these grades 400 m vertically below the surface also suggests the super high-grade epizonal system is telescoping up to higher levels than previously thought (440 m compared to the previously thought 700 m depth) at Sunday Creek, opening further opportunities for bonanza high grades at shallow levels. Additionally, the area immediately west of this new vein is open to the west and to depth.

Pending Results and Update
With four diamond drill rigs operating at site, and A$11.8M cash (as of August 31, 2023), SXG has stated that it will drill an additional 19,000 m by April 2024. SXG has drilled 54 holes for 24,555 m so far in 2023 within the main project area and 12 holes for 2,383 m in regional extensions.
Demonstrating Volume: 18 holes (SDDSC079, 83, 85-86, 88-99, 101, 103) are currently being processed and analyzed, with four holes (SDDSC100, 102, 104, 105) currently in progress (Figures 1-2).
Demonstrating Scale: Recent drilling between 4 km m to 8 km along strike from the main drill area has confirmed the presence of the same dyke breccia host and crosscutting high grade gold-bearing veins as at Sunday Creek. The results, with high grades up to 19.4 g/t gold hosted within a broad and extensive host, are commensurate with the very early drilling undertaken in what is now the core drill area at Sunday Creek. The drill program has proved that the entire 8 km trend and beyond at Sunday Creek is highly prospective for future significant gold discoveries (Figure 4).
Demonstrating Grade: SDDSC082 traverses 18 individual high grade vein sets (Figures 1-3). Seven intervals contained >100 g/t Au (up to 4,190 g/t Au), 20 intervals have >15 g/t Au up to 100 g/t Au and 7 intervals have >5% Sb (up to 24.3% Sb). The hole was drilled parallel to the enveloping host breccia dyke but at a high angle to the predominant NW-SW high-grade vein trend (Figures 1-2).
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. However, 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 mineralized intervals reported are interpreted to be approximately 40 to 50% for SDDSC082 and 60 to 70% of the sampled thickness for other holes reported. Lower grades were cut at 0.3 g/t Au lower cutoff over a maximum width of 3 m with higher grades cut at 5.0 g/t Au cutoff over a maximum of 1 m width, unless otherwise stated.
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: 𝐴𝑢𝐸𝑞 = 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.
