- 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.
