Jaguar Mining Receives Approval for Resumption of Operations at Its MTL Complex (Turmalina Mine), Brazil

Mine operations and ore processing began today at the Turmalina (MTL) Complex

TORONTO, ON / ACCESS Newswire / March 9, 2026 / Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX:JAG)(OTCQX:JAGGF) is pleased to announce that it has received the approval required to begin operations at the Turmalina Mine and associated plants. Today's approval from the Environmental Emergency Office (NEA) represents the removal of the final barrier to starting and ramping up to planned production at the MTL Complex, which includes the mine, the processing plant, the paste fill plant and the filtration unit, with future tailings initially permitted to be used as backfill to the mine.

"Jaguar is grateful for the expeditious review and collaborative treatment of this issue by the NEA, which followed the required approvals from the National Mining Agency (ANM)," commented Jaguar Mining CEO Luis Albano Tondo. "Jaguar is very proud to announce that the goals set out by the Company in resolving this situation in the first quarter of 2026 were successfully accomplished. As part of the removal of this restriction, the NEA has lifted the one remaining embargo on operations at this complex. Jaguar has resumed drilling, blasting and mining activities at the Turmalina Mine and will ramp up toward planned production levels over the next few months.

This approval signals a true turning point for Jaguar Mining," continued Mr. Tondo. "We can now move forward with all aspects of our comprehensive strategic growth plan for 2026 and beyond, which includes this restart at Tourmalina Mine (in the MTL Complex), a restart at Santa Isabel Mine (in the Paciencia Complex) and continued production and development at Pilar Mine (in the Caete Complex)."

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.
