• 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, 2024. 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 Turmalina 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 could 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 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 third largest gold land position in the Iron Quadrangle with over 50,000 hectares.
