NEWS RELEASE November 09, 2023

Mawson’s Subsidiary SXG Drills 20.0 m @ 62.7 g/t Gold Within the RS50 Vein at Sunday Creek

100 m Up-Dip Extension from Previously Announced Results

Up to 1,490 g/t Gold

Assays Pending for 17 Holes

Vancouver, Canada — Mawson Gold Limited (“Mawson” or the “Company”) (TSX:MAW)

(Frankfurt:MXR) (PINKSHEETS: MWSNF) announces further high grades from drill hole SDDSC091 including

20.0 m @ 62.7 g/t Au from 430.0 m drilled in a 100 m up -dip extension of a previous drilled

mineralized zone, at the Sunday Creek Project in Victoria , Australia, owned 100% by Southern Cross Gold

Ltd. (“Southern Cross Gold” or “SXG”) (Figure 7).

SDDSC091, drilled at Rising Sun, is significant as it was drilled to target one vein set, RS50, in a NE to SW

drill orientation (unlike recent west to east drill orientations that targeted multiple veins). The hole hit a

continuous section of high grades (Table 1) with three intervals assaying >50 g/t Au including 0.4 m

@ 950.0 g/t Au, 0.5 m @ 1,490.0 g/t Au and 0.6 m @ 65.4 g/t Au demonstrating the extremely high-

grade tenor and scale of individual veins at the Sunday Creek Project.

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 1-3).

Highlights:

• SDDSC091 drilled at the Rising Sun Prospect intersected 20.0 m (estimated true width or “ETW” 11.6

m) @ 63.6 g/t AuEq (62.7 g/t Au, 0.5% Sb) from 430.0 m including:

o 0.4 m @ 955.6 g/t AuEq (950.0 g/t Au, 3.6% Sb) from 438.4 m, and

o 0.5 m @ 1,497.4 g/t AuEq (1,490.0 g/t Au, 4.7% Sb) from 438.8 m, and

o 0.6 m @ 66.5 g/t AuEq (65.4 g/t Au, 0.7% Sb) from 439.6 m

• SDDSC091 drilled the RS50 vein and is a 100 m up -dip extension from an intersection in drill hole

SDDSC077B (6.5 m @ 10.2 g/t AuEq), previously announced on September 5, 2023 (Figures 1-5).

• Additionally, a further 2 holes (SDDSC079, SDDSC085) are reported from deeper drilling at Apollo.

(Figure 3). These holes are important as they demonstrate the mineralized system extends 500 m below

high-grade drilling at Apollo. Highlights include:

o SDDSC079, a 100 m down dip extension from previous drilling intersected:

 6.3 m @ 4.2 g/t AuEq (3.0 g/t Au, 0.8% Sb) from 567.1 m, including:

• 1.5 m @ 10.7 g/t AuEq (9.2 g/t Au, 1.0% Sb) from 567.1 m

Continued over page

HIGHLIGHTS continued

o SDDSC085, a 180 m down dip extension intersected, intersected visible gold at 727.9 m and

738.0 m, however only a broad low grade “near miss” was intersected from 634 m to 811 m

(177 m down hole length) with best assay 0.3 m @ 8.2 g/t AuEq (6.8 g/t Au, 0.9% Sb) from

634.6 m.

• Seventeen holes (SDDSC83, 86, 89 -90, 92-99, 101-105) are currently being processed and anal yzed,

with four holes (SDDSC100, 106, 107, 108) currently in progress (Figures 1-3)

• Mawson owns 93,750,000 shares of SXG (51%), valuing its stake at A$81.1 million (C$71.6 million)

based on SXG’s closing price on November 8, 2023 AEST.

Noora Ahola, Mawson Interim CEO, states: “The last two months since the release of SDDSC077B have

been a stand out period for Southern Cross Gold. Today’s release is yet another exceptional 20.0 m @ 63.6

g/t AuEq (62.7 g/t Au, 0.5% Sb) from 430.0 m in SDDSC091, that includes 0.5 m @ 1,497.4 g/t AuEq

(1,490.0 g/t Au, 4.7% Sb) from 438.8 m , the third >1,000g/t intercept to come out of the Sunday Creek

project in the last three drill results.

The Sunday Creek discovery in Victoria, Australia is one of the most significant discoveries in the world today

with a frequency of extremely high grades within multiple vein sets (up to 23 defined to date with more being

found) at the property that is second to none.

SXG is well funded (A$11.8 m cash at the end of the August quarter) to deliver on its stated campaign to

complete a further 19 km of drilling to April 2024 from four drill rigs on site delivering a continuous flow of

news flow into the market with over 20 holes being processed and drilled.”

Results Discussion

SDDSC091 drilled at the Rising Sun Prospect intersected 20.0 m @ 63.6 g/t AuEq (62.7 g/t Au, 0.5%

Sb) from 430.0 m (ETW 11.6 m) including:

o 1.0 m @ 6.2 g/t AuEq (5.6 g/t Au, 0.4% Sb) from 432.0 m

o 0.4 m @ 955.6 g/t AuEq (950.0 g/t Au, 3.6% Sb) from 438.4 m

o 0.5 m @ 1,497.4 g/t AuEq (1490.0 g/t Au, 4.7% Sb) from 438.8 m

o 0.6 m @ 66.5 g/t AuEq (65.4 g/t Au, 0.7% Sb) from 439.6 m

o 4.5 m @ 13.8 g/t AuEq (13.5 g/t Au, 0.2% Sb) from 441.4 m

SDDSC091 traversed across a single high -grade vein set and is a 100 m up -dip extension from an

intersection in drill hole SDDSC077B (6.5 m @ 10.2 g/t AuEq), previously announced on September 5, 2023

(Figures 1-4). The individual vein set, RS50, intersected in SDDSC083 is 11.6 m wide (estimated true width),

60 m strike extent currently defined and extends over 500 m down dip and remains open (Figure 4). It is

one of 23 vein sets defined to date at Sunday Creek with the system open in all directions (Figures 4 and 5).

Four of the five best intersections on the project have been drilled over the last 2 months as follows. The

intersection within SDDSC091, based on a 2 m @ 1 g/t Au lower cut off is the second -best intersection on

the project to date. The top ten intersections at Sunday Creek are as follows:

1. SDDSC077B: 3.6 m @ 393.2 g/t AuEq (391.9 g/t Au, 0.8% Sb) from 737.1 m

2. SDDSC091: 20.0 m @ 63.6 g/t AuEq (62.7 g/t Au, 0.5% Sb) from 430.0 m

3. SDDSC082: 1.6 m @ 500.5 g/t AuEq (500.3 g/t Au, 0.1% Sb) from 417.4 m

4. SDDSC082: 1.7 m @ 246.2 g/t AuEq (230.6 g/t Au, 9.9% Sb) from 413.6 m

5. SDDSC046: 14.3 m @ 24.6 g/t AuEq (20.5 g/t Au, 2.6% Sb) from 187.5 m

6. SDDSC082: 4.3 m @ 72.2 g/t AuEq (71.5 g/t Au, 0.4% Sb) from 588.0 m

7. SDDSC066: 1.7 m @ 168.7 g/t AuEq (147.1 g/t Au, 13.7% Sb) from 543.5 m

8. SDDSC082: 9.0 m @ 27.4 g/t AuEq (25.8 g/t Au, 1.0% Sb) from 565.8 m

9. SDDSC033: 16.8 m @ 14.3 g/t AuEq (10.7 g/t Au, 2.3% Sb) from 180.6 m

10. SDDSC025: 11.2 m @ 20.4 g/t AuEq (14.4 g/t Au, 3.9% Sb) from 362.5 m

SDDSC091 hit a continuous section of high grades with three intervals assaying >50 g/t Au including

0.4 m @ 950.0 g/t Au, 0.5 m @ 1,490.0 g/t Au and 0.6 m @ 65.4 g/t Au demonstrating the extremely

high-grade tenor and scale of individual vein sets at the Sunday Creek Project. The ETW of 11.6 m was

calculated from oriented core measurements. Individual assays are show in table 1 below:

Additionally, a further 2 holes (SDDSC079, SDDSC085) are reported from deeper drilling at Apollo. These

were drilled in a NE to SW orientation, to individually test the lower extensions at Apollo (Figure 3). These

holes are important as they demonstrate the mineralized system extends 500 m below high-grade drilling at

Apollo, located 500 m east of Rising Sun. Highlights include:

• SDDSC079, a 100 m down dip extension from previous drilling intersected:

o 1.5 m @ 1.8 g/t AuEq (1.3 g/t Au, 0.3% Sb) from 555.5 m

o 6.3 m @ 4.2 g/t AuEq (3.0 g/t Au, 0.8% Sb) from 567.1 m, including:

 1.5 m @ 10.7 g/t AuEq (9.2 g/t Au, 1.0% Sb) from 567.1 m

SDDSC085, a 180 m down dip extension from SDDSC066 (10.4 m @ 28.7 g/t AuEq (24.8 g/t Au, 2.5% Sb)

from 302.8 m) and MDDSC026 (5.6 m @ 11.5 g/t AuEq (10.4 g/t Au, 0.7% Sb) from 469.7 m) intersected a

very broad low grade “near miss” from 634 m to 811 m (177 m down hole length). The hole intersected

visible gold at 727.9 m and 738.0 m. Better intersections included:

• 0.3 m @ 8.2 g/t AuEq (6.8 g/t Au, 0.9% Sb) from 634.6 m

Pending Results and Update

With four diamond drill rigs operating at site, and A$11.8M cash (as of August 31, 2023) Southern Cross Gold

has stated that it anticipates drilling an additional 19,000 m by April 2024.

Seventeen holes (SDDSC83, 86, 89 -90, 92-99, 101-105) are currently being processed and analyze d, with

four holes (SDDSC100, 106, 107, 108) currently in progress (Figures 1-3).

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 otherwise

where estimated true width “ETW” is stated. During future Mineral Resource studies the requirement for

assay top cutting will be assessed.

Figures 1-7 show project location, plan, longitudinal and cross -sectional views of drill results reported here

and Tables 1–4 provide collar and assay data. The true thickness of the mineralize d intervals reported are

interpreted to be approximately 58% for SDDSC091 and 60% to 70% 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 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 anal ogous 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 March 25, 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: 𝐴𝐴 𝑢𝑢𝐸𝐸𝐸𝐸

= 𝐴𝐴𝑢𝑢 (𝑔𝑔/𝑡𝑡) + 1.58 × 𝑆𝑆𝑆𝑆 (%).

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 𝐴𝐴𝑢𝑢𝐸𝐸𝐸𝐸 = 𝐴𝐴𝑢𝑢 (𝑔𝑔/𝑡𝑡) + 1.58 × 𝑆𝑆𝑆𝑆 (%) is

appropriate to use for the initial exploration targeting of gold-antimony mineralization at Sunday Creek.
