TriStar Gold Reports Positive Court Decision in Civil Public Action on Castelo de Sonhos
None
On December 3, 2025, TriStar Gold announced a court decision regarding the Civil Public Action filed by the Federal Prosecutor's Office (MPF) concerning the environmental licence for its Castelo de Sonhos (CDS) gold project. The judge has declined to rule on the MPF's request for an injunction to suspend the license. Instead, the case will proceed along the normal litigation path, moving into an evidence-production phase.
The court has ordered the MPF and the National Foundation of Indigenous Peoples (FUNAI) to file their replies and identify evidence within 30 working days. Subsequent response periods are set for the State of Pará (10 days) and the company (5 days). TriStar estimates this process will conclude around March 2026. CEO Nick Appleyard stated the company views this decision as "very positive" and is confident in the robustness of its studies which show no impact on Indigenous Lands, located over 20km from the project area.
This news is materially positive for TriStar Gold. The primary risk and overhang on the stock since August 2025 has been the Civil Public Action and the potential for an immediate injunction that would halt all project activities. The court's decision to deny this immediate suspension and move to a formal evidence-based process is a significant de-risking event in the short-term.

Progression from Prior News: The legal challenge was first formally announced on August 6, 2025, causing a sharp drop in the stock price. The company and the State of Pará filed their defenses in September 2025, expressing confidence. This latest court decision validates their view that the MPF's case lacked the urgency and evidence required for an immediate injunction. It demonstrates that the judicial process is functioning and is not simply siding with the prosecutor's office.
-
Materiality: While this is not a final resolution, it removes the most immediate and damaging potential outcome. The market has been pricing in significant legal risk; this decision should alleviate some of that pressure. It allows the company to continue advancing the project with more certainty, although the lawsuit itself remains a key issue to be resolved. The estimated conclusion date of March 2026 provides a clearer, albeit still distant, timeline for final resolution.
-
Expectations: The outcome is in line with the company's confident public statements but likely exceeds the more cautious expectations of the market. Avoiding the injunction is a clear win and a crucial step toward ultimately defeating the lawsuit.
TriStar Gold Inc. is a Canadian-based exploration and development company focused on its flagship Castelo de Sonhos (CDS) gold project in Pará State, Brazil. The CDS project is a paleoplacer deposit, amenable to open-pit mining.
In May 2025, the company released an updated Pre-Feasibility Study (PFS) which showed strong economics, including a post-tax NPV5% of US$603 million and an IRR of 40%, based on a US$2,200/oz gold price. The project's main challenge is a legal action filed by Brazil's Federal Prosecutor's Office seeking to suspend its environmental license, which is the subject of the most recent news.
