- Approval permits the full operation of the Turmalina Mine and the plant, including the paste fill plant

TORONTO, ON / ACCESS Newswire / January 7, 2026 / Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX:JAG)(OTCQX:JAGGF) is very pleased to announce the official approval from the National Mining Agency ("ANM") for the restart of key mining and processing operations at the Company's MTL Complex. This decision marks a significant event in the progress of the Company toward its planned gold production levels, allowing for the resumption of crucial operations, including underground development, underground mining, and the full function of the metallurgical plant, paste fill plant, and filtration unit.

"Jaguar wishes to express its profound gratitude to the ANM for their exemplary diligence and expeditious handling of the review of these operations," commented Jaguar CEO, Luis Albano Tondo. "The decisive action of the AMN and comprehensive review process, culminating in the Termo de Desinterdição Nº 1/2026/ANM/SFI-ANM on January 7, 2026, (a lifting of the restriction on operations) demonstrates ANM's cooperation and signals a mutual commitment to the highest standards of safety and responsible mining. We particularly acknowledge and appreciate their collaborative approach in reaching this significant milestone."

As highlighted by the ANM's decision, this approval enables the execution of Stages 3, 4, and 5 of Jaguar's Gradual Resumption Plan. The Satinoco dry-stacked pile incident, which led to the temporary suspension of operations, has been effectively removed from service, with no additional material to be placed on that stack. Demonstrating the Company's proactive approach and unwavering commitment to the future, Jaguar commissioned a new, state-of-the-art tailings facility recently, now fully ready to support the revitalized operations at the MTL Complex.

The actual resumption of operations is now conditional upon a final clearance from the Environmental Emergency Office (NEA). The NEA is independent from ANM and is exclusively responsible for overseeing environmental matters. The lifting of the NEA embargo order is subject to the NEA's review of the ANM's decision to allow operations at MTL to resume. Immediately upon receipt of the ANM decision, Jaguar submitted this decision to NEA. Jaguar now awaits acknowledgement from NEA so that operations at MTL mining complex may resume.

"This is an incredibly significant milestone for Jaguar," added Mr. Tondo. "Our dedicated teams have worked tirelessly, not just to meet, but to exceed the required safety standards, fundamentally strengthening our operational protocols. The approval of ANM is a powerful affirmation of our sincere commitment to the safety and well-being of our employees, the community, and the environment. While we still need to wait for NEA´s final response to lift this final barrier, we expect the imminent restart of the Turmalina Mine and Plant at the MTL Complex to be a turning point for the Company, injecting immense energy into our ambitious strategy for sustained growth and success throughout 2026 and well beyond."

The Iron Quadrangle
The Iron Quadrangle has been an area of active mineral exploration dating back to the 16th century. The discovery in 1699-1701 of gold associated with iron and platinum-group metals in the southeastern corner of the Iron Quadrangle gave rise to the name of the town Ouro Preto (Black Gold). The Iron Quadrangle contains world-class multi-million-ounce gold deposits such as Morro Velho, Cuiabá, and São Bento. Jaguar holds the second largest gold land position in the Iron Quadrangle with over 46,000 hectares.
