Jaguar Mining drills Paciencia trend, connecting areas of known mineralization in Minas Gerais

Multiple mineralized targets could illustrate a much more extensive gold trend than previously defined TORONTO, ON / ACCESS Newswire / July 8, 2026 / Jaguar Mining Inc. ("Jaguar" or the "Company") is pleased to announce positive results from the first phase of diamond drilling along the corridor that runs from the Chamé exploration target through the Santa Isabel/Marzagao Mine targets and north to the Bahú target area. These drill results confirm significant mineral potential and reveal a large mineral system connecting Chamé, Santa Isabel, Marzagão, and Bahú (from south to north). This defines a new district with over 15 km strike length in the Paciencia Gold District. (See Figures 1 & 2 ) Highlights: 3,764 metres across 17 drill holes Eight holes totaling 2,245 metres at the Chamé target Nine holes totaling 1,518 metres at the Santa Isabel/ Marzagão target Key Intercepts: Chamé Structure: FCM003: 32.21m @ 0.37 g/t Au (including 6.71m @ 1.15 g/t Au) FCM004: 34.30m @ 0.39 g/t Au (including 1.00m @ 2.37 g/t Au) Santa Isabel - Marzagão Structure: FCM008: 7.85m @ 2.03 g/t Au (including 2.00m @ 3.17 g/t Au) FSIEXP009: 2.11m @ 3.10 g/t Au (including 1.11m @ 4.62 g/t Au) All drilling results are detailed in Tables 1 & 2 below.

"The current drilling campaign has successfully demonstrated the physical continuity of the mineralized structure from the Santa Isabel mine toward the Southeast," commented Armando José Massucatto, General Manager of Exploration. "We have also identified a parallel structure in the hanging wall at the Chamé target. The association of these structures confirms the existence of a high-potential district extending over a 15-kilometer trend."
