VANCOUVER, BC / ACCESS Newswire / April 21, 2026 / Sarama Resources Ltd. ("Sarama" or the "Company") (TSX-V:SWA)(ASX:SRR) is pleased to provide a corporate update on matters pertaining to its arbitration claim ("Claim"), Western Australian gold assets, and the acquisition of copper-gold exploration tenements in New South Wales, Australia.

Highlights

• Sarama sells Western Australian Gold assets to Riedel for A$4.6M in cash and shares

• Sarama to hold ~32%^3,4 of Riedel, rising to ~44%^3,4 on performance milestones

• US$242M arbitration claim (+ interest) advancing; hearing set for February 2027

• Strategy preserves exposure to claim and exploration while minimising shareholder dilution

• NSW copper-gold tenure secured; low-cost entry into prospective Lachlan Fold Belt

Sarama's Executive Chairman, Andrew Dinning commented:

"We are pleased to report strong progress in enhancing value across both the arbitration claim and exploration portfolio, providing a clear pathway forward. Finalising the date for the Merits Hearing marks a key milestone in the arbitration process and furthermore, the transaction with Riedel enables Sarama to retain meaningful exposure to its Western Australian gold assets while minimising dilution to any potential future damages award. The addition of new copper-gold tenure in New South Wales provides us with a low-cost opportunity to start building copper-gold optionality into the Company's exploration portfolio while we work through the arbitration process."

Arbitration Proceedings

Procedural Timetable Agreed and Merits Hearing Scheduled

The proceedings arise from the unlawful expropriation of the Company's Tankoro 2 Exploration Permit in Burkina Faso, which was the central component of a multi-million ounce gold development project. The Company is seeking damages of US$242 million, plus interest through arbitration in the International Centre for Settlement of Investment Disputes ("ICSID"), a division of the World Bank Group (refer news release dated 12 December 2024).

Arbitration proceedings against the Government of Burkina Faso ("GoBF") are progressing as anticipated with a number of milestones achieved including the filing of the Company's Memorial, the GoBF filing its Counter Memorial and confirmation of the Procedural Timetable and dates for the Merits Hearing.

On 31 October 2025, Sarama filed its written Memorial (the "Memorial") with ICSID (refer news release dated 3 November 2025), comprising its statement of case, witness evidence and expert reports, and detailing its Claim against the GoBF. The GoBF filed its Counter-Memorial on 30 March 2026.

The Procedural Timetable for the Company's arbitration proceedings against the GoBF has recently been agreed between the parties, and the Company has been advised by ICSID that the arbitral tribunal (the "Tribunal") has confirmed its availability for the proposed dates for the Merits Hearing, with the timetable now confirmed.

Next Steps

The arbitration will now proceed through the following stages:

• document production;

• further written submissions by both parties; and

• pre-hearing procedural steps.

This will culminate in the Merits Hearing 22 February 2027 to 26 February 2027, in which the parties will present their case and supporting evidence to the Tribunal and provide opportunity for witnesses to be cross-examined. The date for the Final Award¹ is yet to be determined.

Representation and Funding

Sarama is represented by Boies Schiller Flexner (UK) LLP, a leading international law firm with extensive experience in investor-state arbitration and a strong track record in the natural resources sector.

The Company has secured a US$4.4 million, four-year non-recourse funding facility to cover all legal fees and expenses related to the arbitration. The facility is secured solely against the Claim and is repayable only in the event of a successful outcome or settlement.

The Company has also retained Accuracy London as an independent quantum expert to provide valuation support for the Claim submitted to ICSID.

Western Australian Gold Assets

As part of the Company's broader equity and capital management strategy, and to manage exposure to the Claim while retaining exploration upside, Sarama has entered into a binding Share Sale Agreement ("SSA") with Riedel Resources Ltd ("Riedel") (ASX:RIE), executed 17 April 2026, to sell its Cosmo and Mt Venn Projects (the "Projects") in exchange for a combination of equity consideration and the payment of certain project-related expenses (the "Transaction").

In connection with the proposed Transaction, Riedel has received commitments to raise A$2.5 million (before costs) via a two-tranche placement at A$0.025 per share to fund exploration across its exploration portfolio and for working capital. On completion, Riedel is expected to have approximately A$4 million in cash².

The Transaction will provide Sarama with a significant equity interest in Riedel, which will be transformed into a well-funded, multi-project gold explorer with several large projects across the Tier 1 jurisdictions of Western Australia and Arizona, USA.

Andrew Dinning has been appointed as a Non-Executive Director of Riedel³, and it is proposed that Paul Schmiede be appointed Chief Executive Officer on completion of the Transaction. Jack Hamilton will fulfil the role of Special Advisor-Exploration with oversight over exploration activities on the three projects. The Company will retain the services of Mr Schmiede and Mr Hamilton as required to ensure continuity of the business, while Mr Dinning will continue in his full-time role as Executive Chairman.

Transaction Summary

Pursuant to the SSA, Riedel will acquire Sarama's interest in the Projects through the acquisition of a 100% interest in Sarama's wholly-owned subsidiary, Yikarri Resources Pty Ltd for consideration comprising equity in Riedel and payment of certain project-related expenses on Sarama's behalf as follows:

• issuance of 150 million shares in Riedel to Sarama (or its nominee) at a deemed price of A$0.025 per share;

• issuance of 100 million performance rights in Riedel to Sarama (or its nominee) across four tranches vesting upon the achievement of certain exploration, mineral resource and share price milestones; and

• payment of project-related costs that are incurred by Sarama, capped at A$300,000 (excluding GST).

Completion is targeted for June 2026, subject to the satisfaction of certain conditions precedent, including (amongst others) Riedel shareholder approval. Further details are included in Appendix A.

On a post-money pro-forma basis, Sarama will hold an initial ~32% relevant interest in Riedel⁴, increasing to up to ~44% if all performance rights vest and are subsequently exercised⁵. Sarama's interest in Riedel will be held via a wholly owned subsidiary.

New South Wales Copper-Gold Project Applications

The Company received documentation from relevant authorities in New South Wales ("NSW") that tenure is now approved for the grant of three early-stage copper-gold exploration tenements in NSW which the Company believes it can potentially add significant value to for minimal expenditure (see Appendix B and Image 1). It is anticipated this will be finalised imminently.

The three exploration licences cover a portfolio of early-stage copper-gold properties in New South Wales, targeting underexplored areas within and adjacent to the Lachlan Fold Belt that are prospective for copper, gold and polymetallic mineralisation.

Three priority areas; Bong Bong Creek, Bald Hill and the Gegedzerick Copper Lode were identified, comprising clusters of historical copper workings and mineral occurrences, and ranked based on prospectivity, access and marketability. These areas are characterised by favourable geological settings, including intrusive and extrusive igneous rocks, historical shafts and workings, and zones of known copper mineralisation with additional gold potential. The Company's application strategy has focused on securing tenure over historically mineralised systems with evidence of high-grade copper mineralisation and strong geological analogues for larger-scale systems.

The Gegedzerick Project is in the Lachlan Fold Belt and is considered prospective for porphyry and intrusion-related copper-gold mineralisation.

The Bald Hill Project is located along the western margin of the New England Orogen and the area is considered prospective for intrusion-related gold systems, with additional potential for porphyry-style copper mineralisation within Lower Permian rocks.

The Bong Bong Project is situated within the central Lachlan Fold Belt and mineralisation is dominated by copper carbonates with minor azurite, chalcocite and chalcopyrite, with gold and silver as secondary targets.

Planned exploration across the Gegedzerick, Bald Hill and Bong Bong Projects will comprise systematic, staged reconnaissance programs aimed at validating prospectivity for porphyry and intrusion-related copper-gold mineralisation and advancing targets toward drilling.
