Jaguar Mining Reports Third Quarter 2024 Production Results

TORONTO, October 10, 2024 - Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX:JAG) today announced preliminary production results for the third quarter of 2024. Full financial results for the quarter will be reported and filed on SEDAR+ on November 7, 2024. All figures are in US Dollars, unless otherwise expressed.

Third Quarter Operating Highlights

• The Company's cash position as at September 30, 2024 increased by 11% to $41.6 million compared to cash of $37.4 million as at June 30, 2024 and $22.0 million at December 31, 2023.

Third Quarter Operating Results

Vern Baker, President and CEO of Jaguar Mining stated:"During the quarter we focused intensely on developing the new areas of our mines, the Faina zone at Turmalina and the BA zone at Pilar. Our production was consistent with the prior quarter, while development meters increased by approximately 8% versus the prior quarter. Much of the development was in the Faina and BA zones. These meters did not produce many ore tonnes as they were focused on accessing development to prepare for the expected ramp-up of production. We also saw a reduction in production from historical areas at Turmalina as the development of new areas was prioritized and resources were reallocated prior to the start of more significant production. Overall tonnage totals decreased slightly during the quarter as efforts focused on development.

While tonnage was lower, grade improved by 24% year-over-year. This is mostly due to more tonnes coming from the Faina zone at Turmalina and significantly better performance on grade at Pilar. While recoveries from the Faina orebody met expectations, the overall recoveries at Turmalina reduced as a result. The Faina zone contributed over 1,800 ounces in the quarter, as our first test stoping came in with a 5.81 g/t grade. Production from the BA zone at Pilar was limited this quarter, as the mine was pushing five accesses into the orebody. These accesses did provide some development ore, but not from the main part of the orebody.

We are very pleased with our quarter-end cash position of $41.6 million. This increase of $4.2 million is after outlays for our new employee profit sharing program, ongoing development, and tax payments, and was despite having fewer ounces sold than produced in the quarter.

Looking ahead, we expect to see a modest improvement in production levels for the fourth quarter, with an ongoing focus on providing sufficient working levels in the new areas to provide a base for higher production in 2025. Our efforts will also continue to focus on advancing development and other new projects. We are working to finalize a contract to initiate a test mining program at our fully permitted Santa Isabel mine, which is part of our Paciência complex and had been on care and maintenance. We are also pleased with our progress on permitting at the Onças de Pitangui project and are continuing to advance permitting at our Córrego Brandão and other open pit opportunities, all of which are expected to contribute to future production growth."

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 42,000 hectares.
