JAGUAR MINING REPORTS FOURTH QUARTER AND FULL YEAR 2024 PRODUCTION RESULTS

AND PROVIDES OUTLOOK FOR 2025

__________________________________________________________________________________________

Toronto, January 13, 2025 – Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX: JAG , OTCQX:JAGGF)

today announced the Company’s production results for the fourth quarter and full year 2024. Full financial results

for the quarter and full year will be reported and filed on SEDAR + on or before March 27, 2025. All figures are in

US Dollars, unless otherwise expressed.

Fourth Quarter and Full Year 2024 Operating Highlights

• Operations at the Turmalina mine were temporarily suspended on December 7, 2024, following a slump in

the north wall of the dry-stacked pile. As a result, production during the fourth quarter and full year 2024

was impacted by the loss of the ounces that had been expected to be produced from this mine in December.

However, the Company’s Pilar mine remains fully operational.

• Fourth quarter consolidated gold production was 14,787 ounces, compared to 16,912 ounces produced in

the third quarter, and 18,482 ounces produced in the fourth quarter of 2023. Annual consolidated gold

production for 2024 was 64,705 ounces compared to 70,702 ounces in 2023. Production at the Pilar mine

increased by 5% and 9% compared to the fourth quarter last year and full year 2023 respectively.

• Fourth quarter consolidated ore processed was 160,430 tonnes at 3.41 g/t compared to 195,595 tonnes at

3.34 g/t in the fourth quarter of 2 023. Annual consolidated ore processed was 695,826 tonnes at 3.41 g/t

compared to 812,954 tonnes at 3.09 g/t in 2023.

• In the fourth quarter, the Company completed primary development of 1,600 metres, secondary

development of 1,260 meters, and exploration development of 80 metres; totalling 2,940 metres compared

to the fourth quarter of 2023 where development totalled 2,793 metres. For the full year 2024, development

completed was 6,701 metres of primary, 4,965 metres of secondary, and 1 69 metres of exploration for a

total of 11,835 metres, compared to the full year 2023 total development of 11,833 metres. Despite the loss

of one third of Turmalina´s development capacity during the quarter, the Company still exceeded prior year

fourth quarter development metres.

• Diamond drilling completed during the fourth quarter was 10,962 metres compared to the fourth quarter of

2023 diamond drilling of 10,271 metres. Diamond drilling completed in 2024 was 38,738 metres compared

to 44,843 metres drilled in 2023. The reduction in drilling year-over-year was the result of eliminating third-

party contract diamond drilling as of the end of 2023. During the fourth quarter, Jaguar’s in-house diamond-

drill crews achieved record monthly totals.

• The Company’s cash position as at December 31, 2024 was $46.3 million compared to cash of $41.6 million

as at September 30, 202 4. During the fourth quarter, the Company benefitted from higher realized gold

prices which was the main driver of the increase in cash.

2025 Outlook

For 2025, given the ongoing suspension of operations at the Turmalina mine, the Company will be focused on its

operating Pilar mine, where production is expected to modestly increase compared to 2024 levels. Development at

Pilar will be enhanced using resources of people and equipment from the Turmalin a mine, which is expected to

modestly increase all-in sustaining costs at the mine while enabling higher production in the second half of 2025.

Any updates on the timing of the resumption of operations at the Turmalina mine will be communicated as soon as

available.

Vern Baker, President and CEO of Jaguar, stated: “As previously announced, in early December we had an incident

at our Turmalina mine where a slump occurred in the north wall of the Satinoco dry -stacked pile . As a result,

operations at the mine remain temporarily suspended while the pile is reconfigured to ensure long -term stability.

We continue working constructively with the Brazilian National Mining Agency and other authorities towards safely

resuming operations as soon as possible.

This incident impacted ounce production in the fourth quarter due to the loss of production from the Turmalina mine

in December. Prior to this incident, we had been on track to exceed last quarters production and be well positioned

for a strong start to 2025. Even without production from the Turmalina mine in December, we were able to increase

our cash balance in the fourth quarter by over $4 million . Strong gold prices and ongoing cost control initiatives

allowed us to maintain a strong balance sheet as we head into what will now be a more challenging first quarter.

During the fourth quarter, ounce production at the Pilar mine was as expected and both development meters and

diamond drilling meters exceeded expectations both increasing significantly compared to the fourth quarter of 2023.

Continuing high development rates, especially in the BA zone, should allow us to start increasing production at the

Pilar mine this year to partly offset the loss of production from the Turmalina mine.

For the first two months of the fourth quarter, the Turmalina mine was doing well on development and diamond

drilling. Overall development rates were 13% higher per day compared to the fourth quarter of 2023, with the

increase coming predominantly from the Faina zone. The mine is well positioned to begin growth in production from

the Faina zone once we resume operations. Ounce production at the Turmalina mine was on track in October and

November, and development of the Faina zone was expected to begin increasing production levels in 2025. A test

of Faina ore was conducted at our Caeté plant during the quarter. Overall recoveries were inline with expectations

and a batch of concentrate has been inventoried for tests.

While we do have some challenges ahead due to the incident at our Turmalina mine, we expect to be back on track

with our growth plan by the end of 2025. This plan c ould potentially see us doubling the Company’s annual

consolidated ounce production over the next five years.”

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

multi-million-ounce gold deposits such as Morro Velho, Cuiabá, and São Bento. Jaguar holds the third largest gold

land position in the Iron Quadrangle with over 50,000 hectares.
