Article content

TORONTO, July 16, 2026 (GLOBE NEWSWIRE) — Belo Sun Mining Corp. (TSX: BSX) (OTCQX: BSXGF) (“Belo Sun” or the “Company”) today announced that a new Civil Public Action (“CPA”) has been filed in Brazil by the Federal Public Defender’s Office (Defensoria Pública da União) against Belo Sun Mineração Ltda., the Company’s wholly-owned Brazilian subsidiary, in connection with the Volta Grande Gold Project (the “Project”). The Brazilian National Indigenous Peoples Foundation (FUNAI) and the State of Pará are also named as defendants in the action.

The Federal Public Defender’s Office is primarily seeking an order requiring that the Mebêngôkre-Xikrin people of the Trincheira Bacajá Indigenous Land be afforded the right to free, prior and informed consultation, in accordance with International Labour Organization Convention No. 169, and be formally included in the Project’s environmental licensing process.

The Company believes the new action should be dismissed, as it is substantially identical to a previous CPA and therefore gives rise to a clear case of lis pendens under Brazilian procedural law.

Article content

The action also requests interim relief suspending the Project’s licences until consultation with the Mebêngôkre-Xikrin people has been completed, as well as the production, on an interim basis, of court-supervised expert evidence regarding the Project’s tailings dam. The claimant further seeks collective moral damages of at least BRL 1,000,000 from each defendant, to be awarded for the benefit of the Indigenous community.

Article content

The potential inclusion of additional Indigenous communities is also currently being addressed with FUNAI in conciliation proceedings conducted before the TRF-1. Under the framework agreed in those proceedings, any eventual inclusion of additional groups must be based on technical criteria and supported by the corresponding technical assessments.

The Company believes these claims are without merit and have already been substantially addressed in prior judicial decisions concerning the Project. Belo Sun will vigorously defend its position in these proceedings and will continue to provide updates as warranted.
