Mawson Gold Limited announced further high-grade mineralization and two new vein sets from four drill holes (SDDSC083, 86, 89 and 90) between the historic Golden Dyke and Christina mining areas, at the Sunday Creek Project in Victoria, Australia, owned 100% by Southern Cross Gold Ltd. ("Southern Cross Gold" or "SXG"). 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 16 holes (SDDSC092-106, 109) are currently being geologically processed and chemically analyzed, and four holes (SDDSC0107, 108A, 110, 111) are in drill progress.

Highlights: High-grade mineralization within two new vein sets have been drilled up to 250 m west and down to 240 m vertically below surface in a previously undrilled area between the historic Golden dyke and Christina mining areas: Drilled footprint of mineralization now extends more than 1.1 km in core area. Mawson owns 93,750,000 shares of SXG (51%), valuing its stake at AUD 90.0 million (C$81.0 million) based on SXG's closing price on November 29, 2023 AEST. The area between Golden Dyke and the historic Christina mine has never been tested by drilling and this initial campaign has been successful in finding two new high grade vein sets.

With SDDSC090 hitting grades up to 0.4 m @ 42.6 g/t Au 250 m to the west of previous drilling, SXG has extended the strike of known mineralization by 29% to 1,100 m. Highlights included 1.5 m @ 2.3 g/t AuEq (2.3 g/t Au, 0.0% Sb) from 334.1 m. With only four holes drilled, the majority of the mineralized host in this area remains untested. With four diamond drill rigs operating at site, and AUD 11.8 million cash (as of August 31, 2023) Southern Cross Gold has stated that it anticipates drilling an additional 19,000 m by April 2024. Cumulatively, 182 drill holes for 48,492 m have been completed at Sunday Creek.

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. SXG considers that it is appropriate to ad opt the same gold equivalent variables as Mandalay Resources Ltd. in its Mandalay Technical Report, 2022 dated March 25, 2022.
