TriStar Gold Provides Update on Civil Public Action on Castelo De Sonhos

TriStar Gold Inc. (TSXV: TSG,OTC:TSGZF) (OTCQB: TSGZF) (the Company or TriStar) is pleased to provide an update on the Civil Public Action initiated by the Federal Prosecutor's Office ("MPF"). Legal filings were submitted in the ongoing Federal Civil Action in Brazil, concerning the environmental licensing of TriStar's Castelo de Sonhos gold project.

The MPF and the National Foundation for Indigenous Peoples (FUNAI) argue that the State of Pará's environmental licensing process failed to properly assess potential impacts on the Indigenous Kayapó communities of the Baú and Menkragnoti Territories. They claim the licensing should have included an Indigenous Component Study (ECI) and formal Free, Prior and Informed Consultation (FPIC).

The State of Pará and TriStar strongly contest these claims. The Company asserts that:

• the environmental impact assessment (EIA/RIMA) was comprehensive, prepared by independent specialists, and underwent more than two years of review by the state regulator (SEMAS);

• technical studies demonstrate no direct or indirect impacts on Indigenous territories;

• hydrological, geological, archaeological, and social assessments show no pathways of impact;

• the project's tailings facility design meets stringent safety standards, and worst-case scenario dam-break modelling shows no risk to Indigenous territories.

TriStar maintains that the licensing is fully compliant with Brazilian regulations. TriStar has demonstrated that FUNAI's own technical assessments did not identify impacts requiring an ECI, and that the action brought by the MPF lacks technical basis. The Company requests dismissal of the lawsuit or, alternatively, a limited technical review that respects the procedural rules.

Nick Appleyard, TriStar's President and CEO stated: "We have now filed our formal response in the proceedings initiated by the Federal Public Prosecutor's Office. The matter has entered the next procedural stage before the Federal Court, and we believe the technical record clearly supports the integrity of the environmental licensing process. We remain confident in the strength of our position and will continue to engage constructively with the authorities to ensure full transparency and regulatory certainty for the project."

Mr. Appleyard continued, "Management remains focused on ensuring regulatory clarity for the project while working toward a timely and constructive resolution of the matters raised in the proceedings."

While this action is ongoing, the Licença Prévia (Preliminary License or LP) for Castelo de Sonhos remains in place, with no restrictions. Please see Figure 1 below for a visual of the Castelo de Sonhos project location relative to Indigenous Territories.
