TORONTO, ON / ACCESS Newswire / January 14, 2026 / Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX:JAG) is pleased to announce its preliminary operating results for the fourth quarter of 2025. These results highlight the Company's resilience and strategic focus as it continues to advance the safe and sustainable resumption of operations at its MTL Complex.

Fourth Quarter and Full Year 2025 Operating Highlights

• Strong cash position: As of December 31, 2025, net cash totalled $60.3 million, up from $45.1 million at the end of the previous quarter and $43.0 million as of December 31, 2024. (As of this quarter, the Company reports net cash position, as opposed to in previous quarters having reported gross cash position (which includes Brazilian export credit loans). Payments and disbursements related to the Satinoco incident, including compensation to affected families, were made during the quarter. The Company also benefited from favorable gold prices, which averaged $4,170 per ouncein the quarter and $3,421 per ounce for the full year.

Luis Albano Tondo, Chief Executive Officer of Jaguar, commented: "This quarter reflects the strength of our people and the culture we are building, grounded in safety, accountability, and operational discipline. Across the business, our teams remained focused on consistent execution while advancing the work required to strengthen reliability, reinforce controls, and reduce operational risk.

Importantly, in early January 2026 we received ANM authorization to lift the operational restriction at the MTL Complex. We view this as a meaningful milestone and a reflection of the progress achieved through a rigorous review process. As we move forward, we will continue to prioritize safe, compliant, and responsible execution at every stage of our operations.

At Satinoco, our team completed the 2025 work program focused on ensuring the pile posed no further geotechnical risk and on supporting the safe release of the previously affected operating areas required to resume production, while maintaining transparent engagement with employees, regulators, and local stakeholders throughout the process.

For the full year, gold production from Pilar totaled 40,012 ounces, with an additional 242 ounces produced from Turmalina related to flotation concentration tests conducted on Faina ore in 2024 and shipped to a smelter in China in 2025, bringing total 2025 gold production to 40,254 ounces. This result was slightly above our expected production level of approximately 40,000 ounces, reflecting disciplined execution and the resilience of our operating teams.

Looking ahead to 2026, our priorities are clear: resume operations at the MTL Complex once final clearance from the environmental authorities (NEA) is received, sustain strong production at the Pilar Mine, and rehabilitate and restart production from the Santa Isabel Mine. This will position all three of Jaguar's complexes to be in operation, supported by strong governance, rigorous planning, and a continued focus on safety and care for our communities and environment."

2026 Outlook

For 2026, given the importance of the MTL Complex to our overall outlook, the Company intends to provide formal production guidance once operations have resumed and sufficient operating visibility has been re-established.
