 accessnewswire.com
 
 TORONTO, ON /  ACCESS Newswire / October 29, 2025 / Jaguar  Mining Inc. (TSX:JAG) ("Jaguar" or the "Company") is pleased to  announce a significant milestone toward the safe and efficient restart  of operations at its MTL Complex, which includes the Turmalina Mine and  processing plant. The Company has received a Partial Suspension of  Interdiction Order (Termo de Suspensão de Interdição) from the Brazilian  Ministry of Labour and Employment in the State of Minas Gerais. This  order formally lifts restrictions on specific sections of the Satinoco  pile at the Turmalina Mine, representing a pivotal advancement in Jaguar's comprehensive plan to resume full operations at the MTL Complex.
 
 The  partial lifting follows a decision by the Regional Labour Court  affirming that Labor Auditors may lift interdictions when safety  conditions are met, without requiring prior external authorization. The  Company has worked diligently with regulatory authorities to ensure all  necessary safety measures and operational protocols are in place for the  areas now released.
 
 Key Terms of the Partial Suspension:
 The order applies to two distinct regions of the Satinoco pile:
 
 
 It is important to emphasize that this is a partial suspension.  Restrictions remain in effect for other areas not explicitly covered by  this order. The Company continues to work proactively with authorities  to address all remaining requirements for a full resumption of  activities at Turmalina.One near the Paste Fill plant and effluent treatment facilities; and
 
Another near the area housing maintenance workshops and a building designated for offices.
 
 
 Strategic Alignment and Operational Impact:
 This  development is a critical step in Jaguar's broader strategy to safely  and systematically resolve all issues related to the Satinoco incident  and to advance toward the complete restart of the MTL Complex. Gaining  access to these specific areas allows the Company to advance  essential preparatory work, including maintenance, infrastructure  assessments, and further safety enhancements, which are  prerequisites to a phased restart. This progress significantly de-risks  the overall restart timeline and reinforces Jaguar's commitment to  operational integrity, safety, and regulatory compliance.
 
 Luis Albano Tondo, Chief Executive Officer of Jaguar, commented: "The  receipt of this partial suspension order for the Satinoco  waste/tailings pile represents a highly encouraging and concrete step  forward in our plan to resume operations at the Turmalina Mine and  broader MTL Complex. While this is a partial lifting, it provides  critical access to key operational areas, including the Paste Fill plant,  allowing us to accelerate preparations for a safe and full restart. We  remain fully focused on fulfilling all outstanding requirements and are  confident that this progress further solidifies our path to bringing the  Turmalina Mine back into production, ultimately delivering enhanced  value to our shareholders."
 
 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  46,000 hectares.
