Star Metro - Jaguar Mining Inc. Reports Second Quarter 2025 Operating Results, Demonstrating Resilience and Strategic Focus While Advancing MTL Restart

Second Quarter Operating Highlights

• 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.

Second Quarter Operating Results

*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:

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."

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.
