JAGUAR MINING INC. RECEIVES FEDERAL AUTHORIZATION TO BEGIN PREPARATORY
WORK AT TURMALINA MINE
_________________________________________________________________________________________
Toronto, August 11 , 2025 – Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX: JAG) is pleased to
announce it has received authorization from the National Mining Agency of Brazil (ANM) to proceed with essential
preparatory work at its Turmalina mine. Operations at the mine have been temporarily suspended since December
2024 following an incident at the Satinoco dry-stacked pile.
While the authorized activities do not directly address the stability of the pile, they are essential to fulfilling all safety
prerequisites required for the phased restart of production. This work includes development of a secondary access
route for the Faina and C-8 orebodies, along with key modifications to the mine’s ventilation system. Implementation
of these began on August 9, 2025.
This federal approval follows the recent issuance of a municipal permit ( Alvará) by the Municipality of Conceição
do Pará, which also allows the Company to begin preparatory work ahead of the anticipated restart of operations.
The municipal permit is valid for three months and may be renewed for an additional three months, supporting the
ongoing work plan.
In parallel, the Company is also finalizing a Term of Agreement with the Public Prosecutor’s Office, which includes
an independent technical audit to confirm safety at Turmalina , as well as a payment to settle the only remaining
public civil lawsuit related to the Satinoco incident of which the Company is aware.
Although full mining activities are not permitted yet, these regulatory milestones mark meaningful progress toward
restarting operations at Turmalina and reflect the Company’s commitment to operating with the highest standard of
regulatory safety, and environmental responsibility.
Work is now underway on the approved activities , with the restart of production still expected to begin in the first
quarter of 2026.
Luis Albano Tondo, CEO of Jaguar, commented: “The federal authorization granted by ANM, together with the
recent issuance of the municipal Alvará permit, demonstrates a well-coordinated and phased regulatory framework
that enables us to initiate essential safety and preparatory work at Turmalina. This is an important milestone in our
ongoing, structured process. With the preparatory activities in the mine underway and following the completion and
independent confirmation of the Satinoco rehabilitation, we expect ANM will lift the remaining suspensions, allowing
for the safe and full resumption of mining operations.”
The Iron Quadrangle
The Iron Quadrangle has been an area of mineral exploration dating back to the 16th century. The discovery in
1699–1701 of gold contaminated 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 45,000 hectares.
