S2 Resources Ltd ('S2' or the 'Company') advises that following the satisfactory completion of due diligence by Vancouver-based Outback Goldfields ('Outback', TSX.V: OZ) on the assets of the Company's wholly-owned Finnish subsidiary Sakumpu Exploration Oy ('Sakumpu'), Outback and S2 have entered into a Letter of Intent ('LOI') in which Outback will purchase Sakumpu from S2 for a total consideration of C$7 million, comprising C$1.5 million in cash and C$5.5 million in shares in Outback

The transaction is subject to a number of terms and conditions which are set out in the LOI and summarised below. Outback intends to undertake a concurrent non-brokered private placement to raise C$5 million as an integral condition of the transaction (the 'Offering') in order to position itself to explore S2's highly

prospective land holding in the Central Lapland Greenstone Belt ('CLGB') of northern Finland, and in particular, advance drilling of the Aarnivalkea gold prospect near Agnico Eagle's Kittila gold mine. The proposed transaction will provide S2 with C$1.5 million (approximately A$1.7 million) cash to supplement its existing treasury, and C$5.5 million (approximately A$6.2 million) worth of shares in Outback. Itis anticipated thatsubject to the exact pricing and size of the Offering, S2 will own approximately 35- 45% of Outback on conclusion of the financing, thereby maintaining material exposure to the exploration upside of the CLGB whilst being able to focus its own funds on its Australian exploration activities. As part of the transaction, S2 will also have the exclusive option to earn majority interests in Outback's four Victorian gold projects, where Outback has recently identified several gold targets.

These properties augment S2's 100% owned Greater Fosterville project, which surrounds Agnico Eagle's Fosterville gold mine. The intended transaction is fully described in Outback's TSX.V announcement of 1 st March 2024 and Corporate Presentation of the same date. It is anticipated that subject to various shareholder and regulatory approvals being received, a definitive agreement will be completed on or around 6 th April 2024. It represents a highly positive outcome for both S2 and Outback, as summarised below.

Key benefits of the transaction for S2 are: S2 receives C$1.5 million cash to supplement its existing cash reserves It enables S2's time and money to be focussed on its core Australian projects It eliminates costs and overheads associated with holding the Finnish ground S2 retains material exposure to the exploration upside of the Finnish assets via its potential significant (35-45%) shareholding in Outback The potential value enhancement of the Finnish assets for S2 by virtue of the greater value recognition for Finnish assets in the Canadian market compared with that on the ASX It ensures the Finnish assets are more efficiently and aggressively explored, with these being Outback's focus It broadens S2's exposure to the gold potential of the Victorian goldfields Key benefits of the transaction for Outback are: The transaction provides Outback with instant exposure to the gold potential of the emerging CLGB province via one of the more significant ground holdings in this highly endowed yet under-explored region which hosts Agnico Eagle's Kittila gold mine, Level 14, 333 Collins Street, Melbourne, VIC 3000, Australia.
