Belo Sun Announces Final Resolution of Civil Public Action

Belo Sun Announces Final Resolution of Civil Public Action

TORONTO, July 27, 2026 -- Belo Sun Mining Corp. (TSX: BSX) (OTCQX: BSXGF) (“Belo Sun” or the “Company”) announces

that Civil Public Action (“ CPA”) No. 0000242-26.2017.4.01.3903 (the “Action”), filed by the Federal Public Defender’s Office

(Defensoria Pública da União, “DPU”) against Belo Sun Mineração Ltda., the Company’s wholly-owned Brazilian subsidiary,

and the State of Pará, in connection with the Volta Grande Gold Project (the “ Project”), has ended with no decision on the

merits. Appeals are no longer possible.

The Action originally challenged the Project's Indigenous Component Study (“ ECI”) for the Installation License (“IL”). It sought

to suspend licensing until additional consultations and studies with local indigenous communities were completed, specifically

the Araras da Volta Grande and Jurunas of Paquiçamba. The Federal Regional Court of the 1st Region (“ TRF1”) unanimously

confirmed the case must be permanently dismissed because it duplicated an earlier lawsuit covering the exact same claims

and remedies. The DPU did not appeal before the statutory deadline, rendering the TRF1’s decision final and binding.

Clovis Torres, Chief Executive Officer of Belo Sun, commented: “This final court ruling is a major milestone for Belo Sun and a

clear validation of our legal position. Other repetitive lawsuits will certainly have the same fate. It reinforces our confidence in

Brazil's judicial framework as we remain focused on advancing the Project responsibly, while maintaining open communication

with local stakeholders, and delivering long-term value for our shareholders.”

Belo Sun will continue to vigorously defend its legal position in the Brazilian courts and will continue to provide updates as

warranted.
