NEWS RELEASE February 12, 2024

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.

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

(Frankfurt:MXR) (PINKSHEETS: MWSNF) announces Southern Cross Gold Ltd. (“Southern Cross Gold” or

“SXG”) has released nine drillholes (SDDSC094A, 96, 98-104) from the Rising Sun area at its 100%-owned

Sunday Creek Project in Victoria, Australia (Figures 1, 4 and 5).

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:

o 2.0 m @ 5.6 g/t AuEq (5.5 g/t Au, 0.1% Sb) from 144.0 m

o 38.2 m @ 3.5 g/t AuEq1 (2.5 g/t Au, 0.6% Sb) from 152.0 m, including:

o 1.9 m @ 19.5 g/t AuEq (16.8 g/t Au, 1.7% Sb) from 469.0 m

o 1.4 m @ 26.6 g/t AuEq (22.8 g/t Au, 2.4% Sb) from 469.5 m

o 2.1 m @ 15.3 g/t AuEq (7.5 g/t Au, 4.9% Sb) from 487.4 m (vein RS10, see Figure 3)

o 1.4 m @ 20.9 g/t AuEq (20.5 g/t Au, 0.2% Sb) from 507.6 m

• SDDSC104 was drilled from the southern margin of the host sequence, intersected the host lower in

the hole and four mineralized vein sets. Highlights included:

o 17.7 m @ 3.8 g/t AuEq (2.3 g/t Au, 0.9% Sb) from 438.0 m

• 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.

• 1.3 m @ 22.1 g/t AuEq (13.0 g/t Au, 5.8% Sb) from 277.3 m (new vein set), including:

o 0.2 m @ 107.4 g/t AuEq (59.2 g/t Au, 30.5% Sb) from 277.9 m

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

o 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).

Rising Sun Lower

SDDSC100 (cumulative 236 g/t AuEq x m ) was drilled through the lower zone of Rising Sun,

demonstrating up and down dip continuity between high-grade intervals intercepted in SDDSC082 and 77B

(released 23 October 2023 and 5 September 2023, respectively). 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. Selected highlights included:

• 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

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 otherwise 1 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 consi sts 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 25 March 2022. The gold equivalence formula used by Mandalay

Resources was calculated using recoveries a chieved 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.
