TriStar Gold Inc. (TSXV: TSG) announced on November 6, 2026 that a Brazilian Federal Court issued an interim ruling on November 4, 2026 regarding environmental licensing of its 100%-owned Castelo de Sonhos gold project in Pará State, Brazil. The ruling provisionally suspends the preliminary environmental licence but expressly permits technical studies, environmental work, and administrative activities to continue. Critically, the Court confirmed the company may proceed with its planned Feasibility Study, which management views as a constructive outcome for the project's development timeline.

Key Points

  • TriStar Gold Inc. (TSXV: TSG / OTCQB: TSGZF) is a mineral development company advancing the Castelo de Sonhos gold project in Pará State, Brazil.
  • A Brazilian Federal Court issued an interim ruling on November 4, 2026 that provisionally suspends, but does not cancel, the project's preliminary environmental licence.
  • The Court requires TriStar and SEMAS/PA to submit additional technical information and evidence within 60 business days of formal notification.
  • Investors may watch whether the Indigenous Component Study and consultation process can be completed concurrently with the Feasibility Study, as the company intends.

Brazilian Court Interim Ruling on Castelo de Sonhos Environmental Licence

The Federal Court of Pará issued its ruling following a Civil Public Action filed by Brazil's Federal Prosecutor's Office against the State Environmental Secretariat of Pará and TriStar's wholly-owned Brazilian subsidiary, Mineração Castelo dos Sonhos S.A. The action sought annulment of the project's preliminary environmental licence until an Indigenous Component Study and a free, prior, and informed consultation process with Indigenous communities were completed. The Court's ruling provisionally suspends the licence's effects rather than cancelling it outright, and prohibits issuance of mine installation or operating authorisations pending further judicial determination.

Feasibility Study Advancement Unaffected by the Ruling

The Court expressly permits TriStar to continue technical and environmental studies, engineering work, and administrative activities associated with advancing Castelo de Sonhos. President and CEO Nick Appleyard stated the ruling "provides clarity on advancing the Project" and that the company has "consistently sought a practical resolution to the issues." The company anticipates, subject to financing, that the Feasibility Study will require approximately two years to complete and will encompass updated mineral resource and reserve calculations, project engineering, metallurgical and geotechnical investigations, and additional environmental studies.

Indigenous Consultation and 60-Business-Day Court Submission Requirement

The Court has directed the preparation of an Indigenous Component Study and the implementation of a free, prior, and informed consultation process, with participation from relevant Brazilian authorities. TriStar and SEMAS/PA are required to present additional technical information and evidence of steps taken to address identified matters within 60 business days of formal notification. The Court clarified this period is for document submission only, and does not constitute a deadline for concluding the Indigenous consultation process, which will follow procedures specific to the communities concerned.

TriStar's Parallel Workstream Strategy for Castelo de Sonhos

TriStar has stated its intention to advance the Feasibility Study and the required environmental and Indigenous consultation processes concurrently, and does not anticipate an adverse impact on project development timelines. The company stated it will work with legal and environmental advisers alongside relevant Brazilian authorities and will also consider all available legal options. TriStar described its commitment to responsible project development, constructive stakeholder engagement, and compliance with applicable Brazilian environmental and regulatory requirements.
