Jaguar Mining Reports Second Quarter 2025 Operating Results, Demonstrating Resilience and Strategic Focus While Advancing MTL Restart

TORONTO, ON / ACCESS Newswire / July 9, 2025 / Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX:JAG) is pleased to announce its preliminary operating results for the second quarter of 2025, demonstrating the Company's operational strength and strategic agility. These results highlight a commitment to sustainable growth and operational excellence, laying a strong foundation for future success. Full financial results for the quarter will be reported and filed on SEDAR+ by August 14, 2025. All figures are in US Dollars, unless otherwise expressed.

Second Quarter Operating Highlights

  • In the second quarter, the Company achieved consolidated gold production totaling 10,973 ounces. This output was supported by strong production from the Pilar mine, which contributed 10,731 ounces, along with 242 ounces from a successful metallurgical test utilizing Faina material. This tested material, processed at the Caeté plant, was sold and contributed to the quarter's gold production. While this represents a temporary shift in operational focus compared to the 17,244 ounces produced in the second quarter of 2024 (which included production from both the Pilar and Turmalina mines), the variance is primarily due to the temporary suspension of operations at the Turmalina mine. This suspension was imposed by regulatory authorities following a localized incident at the Satinoco dry-stacked facility. The Company continues to engage collaboratively with all stakeholders and to reaffirm its unwavering commitment to safety and environmental stewardship.

  • The Pilar mine delivered strong operating results during the quarter, producing 10,731 ounces of gold from 92,846 tonnes, at an improved 4.04 g/t head grade and 89% recovery. These results reflect tangible progress compared to the second quarter of 2024, when the mine produced 10,694 ounces at 3.83 g/t and 88% recovery. Pilar successfully increased output by 37 ounces year-over-year, while also achieving a five percent improvement in head grade and a one percent enhancement in plant recovery. This performance reflects improved efficiency initiatives at the Pilar mine.

  • Strategic development at Pilar progressed this quarter, with a total of 1,488 meters completed. Work remained focused on advancing the BA zone and the expansion of the SW ore body in the upper mine levels, both were supported by the additional resources from the MTL team. The Company also extended essential emergency routes and exits. This approach resulted in a significant acceleration of development efforts, representing a 377-meter increase - a 34% improvement - compared to the second quarter of 2024.

  • Drilling initiatives in the second quarter of 2025 demonstrated strong growth, with a 51% increase in total meters drilled compared to the prior year period. This progress highlights significant advancements in productivity and overall efficiency, driven by key strategic enhancements: the expansion of drilling teams at Pilar, the integration of an advanced Smart rig, and the strategic reallocation of resources from Turmalina. Additionally, effective equipment management, coupled with the leveraging of automation within the Smart rigs, played a crucial role in minimizing downtime and elevating performance levels. Collectively, these achievements reinforce the Company's commitment to continuous improvement and operational excellence.

  • The Company's cash position as of June 30, 2025, was $48.3 million, increasing from $40.3 million in the previous quarter and $46.3 million as of December 31, 2024. In the second quarter, payments and ongoing disbursements were made related to the Satinoco dry-stacked facility incident, including compensation to affected families. The Company also benefited from favorable gold prices during the quarter, which averaged $3,264 per ounce, compared to a year-to-date average of $3,078 per ounce.

*A total of 242 ounces was produced and sold, originating from a metallurgical test conducted using material from Faina pertaining to 2024 production. Further details are provided in the following section.

Faina Material Testwork and Strategic Production Alternatives

A metallurgical test was recently conducted using material mined from the Faina deposit, corresponding to 2024. Approximately 242 ounces of gold were produced and sold in the second quarter of 2025 as a result of this test. The material was concentrated through flotation at the Caeté plant, with the resulting concentrate exported to a smelter-refinery in China to be converted into pure gold bars.

Results from this test work are currently pending confirmation from the refinery in China. Until these results are confirmed, specific figures related to mass, grade, and metallurgical recovery have not been consolidated or disclosed.

The flotation test is part of an ongoing program of evaluating alternative processing routes to significantly improve Faina metallurgical recovery. Exploring these alternative processing routes highlights a proactive strategy of ensuring continued gold output and operational flexibility.

Advancing Towards the Resumption of MTL Operations: A Structured and Responsible Pathway

Following the Satinoco dry-stacked facility incident, the Company has remained firmly committed to safety, environmental stewardship, and the well-being of the local community.

In close consultation with the applicable governmental agencies in Brazil, the Company has developed a carefully structured and comprehensive plan to support the safe and sustainable restart of operations at the MTL complex. As part of this process, the Company will undertake the necessary technical studies and implement required construction adjustments to ensure the geotechnical safety factors at Satinoco meet or exceed industry standards.

These geotechnical safety factors will be validated by an independent consultant selected by the authorities, and full resumption of operations will depend on the lifting of restrictions once compliance has been confirmed. The plan consists of a series of critical phases and deliverables, each reflecting a commitment to a responsible and structured reinstatement.

The plan is comprised of the following interconnected stages:

1.

Comprehensive Stabilization and Engineering Studies

 

The initial stage focuses on ensuring the long-term stability and integrity of the Satinoco dry-stacked facility, including detailed technical assessments and the implementation of robust engineering solutions.

 
  • Notably, this encompasses a thorough rupture and sensitivity analysis for all slopes, which is providing information for the detailed design of the facility's final geometry. Additionally, the bottom drainage system is being addressed, from conceptualization to execution and as-built validation, to further strengthen the structural integrity.

 
  • In parallel, a key milestone is the creation of a new area for future tailings disposal: the Company is reconfirming and lining the existing Faina open pit to safely receive tailings for the next two years of operations. Looking further ahead, the Company has secured a new, permanent disposal area nearby, with sufficient capacity to store all MTL tailings over the entire Life of Mine, ensuring long-term sustainability and compliance.

2.

Regulatory Engagements and Legal Resolutions

 

The second stage centers on transparent engagement with regulatory bodies and the resolution of legal matters. Efforts are concentrated on securing all necessary approvals and aligning with the expectations of the relevant authorities.

 
  • Key milestones include finalizing the Termo de Ajustamento de Conduta (TAC), maintaining active collaboration with the Environmental Foundation of Minas Gerais (FEAM) and the National Mining Agency (ANM), and presenting the comprehensive resumption plan. Constructive dialogue is also ongoing with the Ministry of Labor and Employment, as well as the Public Prosecutor's Office. Additional priorities include advancing the resolution of pending Public Civil Actions and confirming the final compensation amounts.

 
  • Negotiations concerning fines and other legal matters are well advanced with various authorities; however, no additional agreements have been signed at this time. The only agreement executed to date is with the Public Defender's Office (press release dated March 26, 2025), which relates specifically to the methodology used for calculating compensation to affected individuals - a matter that has already been publicly disclosed. The Company will promptly issue a press release if any material developments occur, including without limitation, the finalization of any additional agreements.

3.

Operational Readiness and Infrastructure Reinstatement

 

In the third stage, which runs in parallel to the regulatory progress, the Company is preparing operations for a safe and efficient restart. This stage involves the restoration of essential infrastructure and ensuring comprehensive workforce readiness.

 
  • Main activities include phased manpower remobilization, establishment of temporary administrative facilities, and critical enhancements such as emergency exit and ventilation adaptations.

 
  • Preparations for the pastefill plant-including preventive maintenance and yard impermeabilization-are planned to commence as soon as the corresponding permits are granted. Attention to obtaining the necessary municipal permits continues to be a priority.

4.

Final Permissions for Resumption

 

The final stage marks the culmination of the process, with the granting of formal authorization to resume operations.

 
  • Achieving this milestone will signify the successful completion of all preceding phases, affirming the Company's readiness to recommence activities with full regard for safety and compliance.

While not guaranteed, the Company's current best estimate is that operations at the MTL complex could resume in the first quarter of 2026. Throughout each phase, teams remain committed to the highest standards of operational excellence and corporate responsibility. This structured approach underscores a continued focus on building a resilient and sustainable future for the MTL complex, its workforce, and the surrounding communities.

Vern Baker, Director and CEO of Jaguar stated: "In the second quarter of 2025, we achieved consolidated gold production of 10,973 ounces. This output was delivered during a period requiring strategic adaptation due to the temporary suspension of operations at the Turmalina mine. The Pilar mine delivered a strong performance, producing 10,731 ounces and increasing development rates significantly. We also saw tangible year-over-year improvements at Pilar, including a five percent increase in head grade and a one percent improvement in plant recovery, reflecting efforts to improve operational efficiency. Financially, our cash position strengthened to $48.3 million as of June 30, representing an increase from the prior quarter, supported by favorable gold prices which averaged $3,264 per ounce. These results reflect continued efforts to maintain operational stability and financial resilience during a period of transition."

Luis Albano Tondo, Deputy CEO of Jaguar stated:"Addressing the Satinoco dry-stacked facility incident at our MTL complex remains our paramount focus, underscoring our commitment to safety, environmental responsibility, and the well-being of our community. We are steadily progressing through a structured and comprehensive process aimed at working towards the safe and sustainable resumption of operations at the MTL complex. Our plan outlines essential phases, beginning with initial stabilization and engineering studies-which includes preparing a new area within the Faina open pit for tailings disposal-followed by necessary regulatory engagements and legal resolutions in close collaboration with authorities. This will be succeeded by operational readiness and infrastructure reinstatement, culminating in securing the required approvals to resume operations. This is a complex and multi-faceted undertaking, and we are diligently working towards our current target of resuming operations in the first quarter of 2026. Our collective efforts remain firmly focused on ensuring a responsible and sustainable future for our operations and all stakeholders."
