NEWS RELEASE March 30, 2023
Mawson’s Subsidiary SXG Reports 249.5 g/t Gold Over 0.3 Metres in 270 Metre Step Out at
Sunday Creek, Victoria, Australia
Vancouver, Canada — Mawson Gold Limited (“Mawson” or the “Company”) (TSX:MAW)
(Frankfurt:MXR) (PINKSHEETS: MWSNF) announces results from six further drill holes (SDDSC056 -58, 61,
63 and 65) at the Sunday Creek Project in Victoria (Figure 1). 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 both
in the main drill area and up to 7.5 km along strike at the Tonstal prospect with 13 holes being processed
and analyzed or in progress. Mineralization now extends in the main drill area over 1,350 m from Christina
in the far west to SDDSC063.
Highlights:
• Drill hole SDDSC061 is a large 270 m step out vertically below the Rising Sun Shoot.
Multiple points of visible gold (Photos 1 and 2) were observed between 691.0 m to 695.1 m in
SDDSC0061 and is the second deepest intersection on the project to date. Highlights included:
• 12.0 m @ 7.4 g/t AuEq (7.4 g/t Au, 0.0 %Sb) from 688.0 m
▪ including 0.3 m @ 249.5 g/t AuEq (249.5 g/t Au, 0.0 %Sb) from 691.1 m
• SDDSC063, a 200 m near-surface step out from prior drilling at Apollo East targeted
mineralization below surface trenching intersected the first drilled in the area. Highlights
included:
• 2.7 m @ 4.4 g/t AuEq (3.4 g/t Au, 0.7 %Sb) from 24.0 m
▪ including 0.5 m @ 17.2 g/t AuEq (12.2 g/t Au, 3.2 %Sb) from 26.2 m
• Drill hole SDDSC056, drilled to test a near surface gap between Apollo and Gladys intersected:
• 1.0 m @ 11.7 g/t AuEq (0.1 g/t Au, 7.4 %Sb) from 77.0 m
• 19.6 m @ 1.5 g/t AuEq (1.0 g/t Au, 0.3 %Sb) from 132.0 m
▪ including 0.5 m @ 25.7 g/t AuEq (9.9 g/t Au, 10.0 %Sb) from 134.5 m
▪ including 0.5 m @ 6.3 g/t AuEq (6.3 g/t Au, 0.0 %Sb) from 150.1 m
• 2.4 m @ 3.8 g/t AuEq (3.5 g/t Au, 0.2 %Sb) from 172.6 m
▪ including 0.6 m @ 10.8 g/t AuEq (9.9 g/t Au, 0.6 %Sb) from 173.8 m
• SXG now has four rigs drilling at Sunday Creek, three in the main drill area and the fourth up
to 7.5 km along strike at the Tonstal prospect with 13 holes being processed and analyzed or in
progress.
• Mawson owns 93,750,000 shares of SXG (51%), valuing its stake at A$64.7 million (C$58.7 million)
based on SXG’s closing price on March 29, 2022.
Noora Ahola, Mawson Interim CEO, states: “We are pleased with the expansive drill campaign
being undertaken by SXG at Sunday Creek that is bearing great results. SDDSC061 is the second
deepest hole at the property and a 270 m step out below the Rising Sun shoot that intersected
0.3 m @ 249.5 g/t Au within a broader interval and encouragingly sees the system transitioning
at depth, with visible gold, in a similar manner to what is observed at other epizonal deposits
that are in production in Victoria.
“Also exciting is SDDSC063 that has again extended the mineralized zone to the east of Apollo
by a further 200 m with grades of up to 12.2 g/t Au and 3.2% Sb from 26.2 m and beneath a
surface trench that previously returned 8.0 m @ 19.6 g/t Au and 0.4% Sb (true width 3 m).
“SXG has successfully increased the size of its main drill area to 1,350 m along strike and 800 m
to depth and with the recently mobilized fourth rig at the Tonstal prospect around 7.5 km to the
north-east of the main drill area, we expect known mineralization to increase further still at
Sunday Creek.”
Results Discussion
The Sunday Creek epizonal-style gold project is located 60 km north of Melbourne within 19,365 hectares of
granted exploration tenements. SXG is also the freehold landholder of 133 hectares that forms the key portion
in and around the drilled area at the Sunday Creek Project.
Sunday Creek has a n 11 km mineralized trend that extends beyond the main drill area and is defined by
historic workings and soil sampling which is being drill tested for the very first time with the fourth drill rig
which mobilized to site just over a week ago.
Rising Sun Prospect
Drill hole SDDSC061 is a large 270 m step out vertically below the Rising Sun Shoot and intersected:
• 8.0 m @ 1.3 g/t AuEq (1.2 g/t Au, 0.1 %Sb) from 656.0 m
• 12.0 m @ 7.4 g/t AuEq (7.4 g/t Au, 0.0 %Sb) from 688.0 m
o Including 0.3 m @ 249.5 g/t AuEq (249.5 g/t Au, 0.0 %Sb) from 691.1 m
SDDSC061 is located 270 m below the Rising Sun intersection in SDDSC050 which returned 14.5 m @ 4.9
g/t AuEq (4.2 g/t Au, 0.5% Sb) from 439.8 m. Multiple points of visible gold (Photos 1 and 2) were observed
between 691.0 m to 695.1 m in SDDSC0061. SDDSC06 1 is located 187 m west in a horizontal plane from
SDDSC050 and is the second deepest mineral ized intersection on the project to date at 690 m
vertically below surface. Results are only presented from 27-76 m and 620-770m in SDDSC061, whilst assays
from 76 m–399 m are still being awaited, but not expected to produce higher grades. The last assay in the
hole between 769-770 m assayed 0.7 g/t Au with further assaying at depth ongoing.

Apollo East Prospect
Drill hole SDDSC063, a 200 m step out from prior drilling at Apollo East targeted mineralization found in
surface trenching (8.0 m @ 19.6 g/t gold and 0.4% antimony (true width 3 m) and 2 m @ 4.9 g/t gold and
0.2% antimony (true width 2 m)). SDDSC063 intersected:
• 2.7 m @ 4.4 g/t AuEq (3.4 g/t Au, 0.7 %Sb) from 24.0 m
o Including 0.5 m @ 17.2 g/t AuEq (12.2 g/t Au, 3.2 %Sb) from 26.2 m
SDDSC063 is located 935 m from SDDSC061 and mineralization now extends in the main drill area over 1,350
m from Christina in the far west to SDDSC063.
SDDSC065, also drilled at Apollo East, drilled 12 m SE of SDDSC063 and intersected the edge of the
mineralized body with anomalous but low grade mineralization intersected: 1.3 m @ 0.2 g/t AuEq (0.1 g/t
Au, 0.0 %Sb) from 26.2 m and 3.5 m @ 0.1 g/t AuEq (0.1 g/t Au, 0.0 %Sb). from 31.5 m.
Apollo-Gladys Prospects
Drill hole SDDSC056, drilled to test a near surface gap between Apollo and Gladys intersected:
• 1.0 m @ 11.7 g/t AuEq (0.1 g/t Au, 7.4 %Sb) from 77.0 m
• 19.6 m @ 1.5 g/t AuEq (1.0 g/t Au, 0.3 %Sb) from 132.0 m
• Including 0.5 m @ 25.7 g/t AuEq (9.9 g/t Au, 10.0 %Sb) from 134.5 m

Drill hole SDDSC057 testing a gap lower in the Apollo area intersected lower grade gold and arsenic
mineralization over 16.4 m @ 0.8 g/t AuEq (0.3 g/t Au, 0.3 %Sb) from 325.2 m (20m @ 0.1 g/t Au low er
cut-off), which included 0.8 m @ 11.7 g/t AuEq (2.0 g/t Au, 6.1 %Sb) from 328.2 m.
Golden Dyke Prospect
SDDSC058, the first of three holes drilled below old workings at Golden Dyke intersected the halo to
mineralization with broad and low -grade gold and arsenic noted including 19.0 m @ 0.2 g/t AuEq (0.2 g/t
Au, 0.0 %Sb) from 220.0 m (20m @ 0.1 g/t Au lower cut-off).
Further discussion and analysis of the Sunday Creek project by Southern Cross Gold is available on the SXG
website at www.southerncrossgold.com.au
Figures 1-5 show project location and plan and longitudinal and cross-sectional views of drill results reported
here and Tables 1 –3 provide collar and assay data. The true thickness of the minerali zed interval is
interpreted to be approximately 60% - 70% of the sampled thickness. DSSC0061, given its depth and
deviation, was drilled at a higher angle to mineraliz ation with true thickness of the mineralized interval
reported interpreted to be approximately 50% of the sampled thickness. Lower grades were cut at 0.3 g/t
lower cutoff over a maximum of 3 m with higher grades cut at 5.0 g/t AuEq cutoff over a maximum of 1 m.
Update on Current Drilling
Drilling with four rigs is in progress at Sunday Creek at the Golden Dyke, Rising Sun and Apollo prospects.
Nine holes (SDDSC059, 60, 62, 64, 66, 67, 69, SDDTS001-2) are being geologically processed and analyzed,
with four holes (SDDSC068, 70, 71, SDDTS003) in drill progress (Figure 2). These holes will provide continual
news flow. Drill holes awaiting assays or in progress include the deepest drill holes drilled on the project at
Rising Sun (SDDSC064/67/70) and Apollo (SDDSC066/68). SDDSC064 is the first hole to exceed 1 km depth
on the project, terminating at 1013.5 m.
Technical Background and Qualified Person
The Qualified Person, Michael Hudson, Executive Chairman and a director of Mawson Gold, and a Fellow of
the A ustralasian 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.
