Jaguar Mining drills consistent results at BA Zone, Pilar gold mine, Brazil

Technical update on exploration drilling & resource expansion strategy TORONTO, ON / ACCESS Newswire / June 15, 2026 / Jaguar Mining Inc. ("Jaguar" or the "Company") is pleased to report the latest results from its ongoing diamond drilling program at the Pilar Gold Mine ("Pilar"), 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. These results support a key component of the Company's strategy to de-risk and convert its current exploration targets into formal Mineral Resources.

Highlights Proven Continuity: Drilling confirms that the BA Zone mineralization extends over 1.5 km down-plunge and remains open at depth, indicating significant untapped potential (see Figure 1 ). High Geological Confidence: Consistent gold grades and structural thickness support high-certainty modeling for an additional 300 vertical meters beyond current mining levels. Resource Growth Potential: 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 (LOM).

Superior Grades: 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 (see Table 1 ). Assay Highlights (full results in Table 1 ) "The consistency of the BA Zone at depth is a testament to the quality of the Pilar orebody," stated Armando Massucatto, General Manager of Exploration of Jaguar. "By balancing technical precision with our operational goals, we are demonstrating that the potential of this exploration target is not just theoretical, but a tangible pathwa
