Jaguar Mining Commences Directional Drilling Program At Pilar Gold Mine Jaguar Mining Inc. began the planned directional drilling program at the Company’s Pilar gold mine earlier this week. The 5,000 metres of specialized drilling will explore three mineralized zones below the current Pilar mine workings which now extend to a depth of 1,100 metres (1.1km). Drilling to be conducted across three zones, identified at the BA Zone, the LPA Zone and the BF Zone, will be completed in three phases. This program is part of the 227,200-metre, 5-year exploration drilling program the Company announced last month, engaging both Geosol and Major Drilling companies, to focus on both green and brown field exploration. The Pilar drill program is expected to continue for the next 10-12 months. Both current mining and conventional drilling at the Pilar mine have proven that both grade and mineralization widths have been increasing at depth. Recent drilling results successfully targeted the down-plunge extensions of the BA Zone within the Pilar mine, demonstrating that high-grade mineralization remains robust and predictably continuous at depth. These results support a key component of the Company’s strategy to de-risk and convert its current exploration targets into formal mineral resources. Currently, the geometry of the BA, LPA, and BF ore bodies at the Pilar mine exhibits an east-west (E-W) elongation trend. As a result, the tight folds observed in the upper levels progressively transition into more open fold geometries at depth, leading to an increase in the mineralized area. In addition, the mineralized horizons show a noticeable thickening associated with a reduction in structural constriction. With respect to grade distribution, both mining exposures and drilling data indicate an overall increase in grade at depth when compared to the upper levels of the deposit. A direct consequence of this elongation is the geometry of additional mineralized lenses and a corresponding increase in grade variability. However, when both the mineralized area and grade are considered together, the ounces per vertical metre (oz/vm) ratio continues to increase, indicating gains in both mineralized mass and grade tenor at depth. Directional drilling will begin at this level. While conventional drilling pushes straight down in a single vertical path, frequently requiring multiple drill rigs and a larger drill area footprint to access a large target, directional drilling intentionally steers the drill bit, allowing operators to curve, angle, and branch multiple boreholes from a single surface location to precisely intercept complex ore bodies. The Company believes that the property has the potential for additional ounces below the extent of the current active underground workings. This is based on previous exploration on the property, including over 2,873 historic drill holes. The exploration target potential was derived by modeling the identified vein systems, and their surrounding “halo” mineralization, as evidenced by drill intercepts in the exploration target area, across vertical long sections of the mine area. There has been insufficient exploration to define a mineral resource with respect to the exploration target, and the Company cautions that there is a risk further exploration will not result in the delineation of a mineral resource.

Jaguar Mining Reports Consistent Drilling Results At The BA Zone Of The Pilar Gold Mine Brazil Demonstrating Down-Plunge Continuity Jaguar Mining Inc. reported the latest results from its ongoing diamond drilling program at the Pilar Gold Mine, located within the Iron Quadrangle in Minas Gerais, Brazil. The current campaign successfully targeted the down-plunge extensions of the BA Zone within the Pilar Mine, demonstrating that high-grade mineralization remains robust and predictably continuous at depth. Drilling confirms that the BA Zone mineralization extends over 1.5 km down-plunge and remains open at depth, indicating significant untapped potential. Consistent gold grades and structural thickness support high-certainty modeling for an additional 300 vertical meters beyond current mining levels. These results validate the strategy to convert the gold mineralization in this highly prospective exploration target into formal Mineral Resources, supporting the potential expansion of the Life of Mine. Key intercepts significantly exceed the mine's current average reserve grade, including 5.30m @ 8.52 g/t Au and 10.00m @ 5.82 g/t Au. The mineralized zones at the Pilar Mine are primarily hosted within a robust Banded Iron Formation sequence. The gold mineralization is structurally controlled by the intersection of regional fold axes with the Banded Iron Formation layer, which creates concentrated mineralized shoots of higher-grade material. The open nature of these folds at depth is a critical factor for the deposit's scale. These structural elements provided the necessary accommodation space for the circulation of gold-bearing hydrothermal fluids during the mineralizing event. Because these folds are continuous and well-defined, the resulting mineralization follows a predictable geometry. The risk of losing the mineralized zone at depth is significantly reduced, as the geological model continues to be validated by every new drill hole. The following table summarizes the most significant intercepts from the recent drilling campaign at the BA Zone. All grades are reported as uncut, and widths represent the Estimated True Width. The Company believes that the property has the potential for additional ounces below the extent of the current active underground workings. This is based on previous exploration on the property, including over 2,873 historic drill holes. The exploration target potential was derived by modeling the identified vein systems, and their surrounding halo mineralization, as evidenced by drill intercepts in the exploration target area, across vertical long sections of the mine area. There has been insufficient exploration to define a mineral resource with respect to the exploration target, and the Company cautions that there is a risk further exploration will not result in the delineation of a mineral resource. Jaguar Mining maintains a rigorous QA/QC program at the Pilar Mine. All diamond drill core is logged, photographed, and split with a diamond saw at the Company’s secure facility. Samples are transported to the Company’s on-site laboratory or accredited third-party laboratories. The program includes the insertion of certified standards, blanks, and duplicates into the sample stream to ensure the precision and accuracy of the analytical results.
