Jaguar Mining Provides Update on Permitting of the Onças de Pitangui Development Project, Minas Gerais, Brazil

TORONTO, ON / ACCESS Newswire / November 2, 2026 / Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX:JAG) is providing an update on the licensing of its Onças de Pitangui underground gold project in Minas Gerais, Brazil (the "Project"). On October 30, 2026, the state environmental authority (URA Alto São Francisco, FEAM) issued a decision denying the Project's combined Preliminary and Installation Licence (LP+LI) application.

Licensing Update and Next Steps

The decision made by the state environmental authority follows a technical opinion issued on October 29, 2026, recommending the denial, which was then formally issued on October 30^th by the URA. It cites a number of grounds, including the insufficiency of certain technical data. The URA statement contains NO findings indicating that the project is environmentally unfeasible. It speaks of viability "not demonstrated at this time". Its conclusion states only that control systems must be re-evaluated, and it invites a new, properly documented application.

Management Comment

"We are disappointed by the decision. We remain committed to the development of the Onças de Pitangui project and to constructive engagement with the authorities and the communities close to the Project," commented Jaguar CEO Luis Albano Tondo. "We will correct the deficiencies identified by the URA in the Environmental Impact Study and resubmit it, and we will continue working hard to advance the Project's licensing."

The Onças de Pitangui Project

The Onças de Pitangui project, acquired from IAMGOLD in September 2023, is located approximately 110km northwest of the city of Belo Horizonte in the state of Minas Gerais, Brazil and 30km from Jaguar's Turmalina processing plant.

Jaguar conducted additional exploration following the acquisition. The existing resource is comprised of 2,122,000 tonnes grading 4.16g/t gold for 286,000 ounces in the Proven & Probable category, 3,547,000 tonnes grading 4.01g/t gold for 457,000 ounces in the Measured & Indicated category and 4,184,000 tonnes grading 3.64g/t gold for 490,000 ounces in the Inferred category.
