Jaguar Mining Intersects High-Grade Gold at Faina Orebody,
Confirming Continuity of Mineralization at Turmalina Mine
- Multiple high-grade zones intersected, including 11.88 g/t gold over 5.39 metres
__________________________________________________________________________________________
TORONTO, Ontario – July 27, 2026 – Jaguar Mining Inc. ("Jaguar" or the "Company") is pleased to announce
that the initial drilling campaign at the Faina orebody, located within the Turmalina Mine complex, has
successfully intersected multiple high-grade gold zones. These results confirm the continuity of mineralization and
support the Company's strategy to expand Mineral Resources within the Faina orebody , one of four orebodies
that comprise the Turmalina mine.
Since Jaguar Mining obtained permission to resume activities at the Turmalina operations (see Jaguar Mining
News Release dated March 9, 2026), resource conversion and new resource drilling activities have been
increased, providing the foundation for the full resumption of mining operations at the Faina orebody , which is
located to the NNW of current mining activities at the Turmalina mine. (See Figures 2-7 below).
HIGHLIGHTS
High-Grade Gold Intercepts: Initial drillholes returned significant gold grades, including:
● 3.40m @ 7.67 g/t Au (FAI0177)
● 5.39m @ 11.88 g/t Au (FAI0178)
● 2.14m @ 9.01 g/t Au (FAI0182)
● 3.13m @ 22.46 g/t Au (FAI0182)
Exploration Success: The drilling confirms the presence of robust mineralization within the Faina target zone
and demonstrates the effectiveness of the current exploration strategy.
Model Validation: The drilling results successfully validate the current geological model while refining the
geometry and continuity of the mineralized lenses. This improved understanding of the orebody provides greater
confidence for short- and medium-term mine planning and stope design.
Resource Growth Opportunity: These encouraging initial results reinforce the potential to expand Mineral
Resources at Turmalina and support future underground mine development.
"These results validate the long-term geological model of the Faina orebody, illustrating the continuity of the
mineralized bodies both across strike and at depth, and opening the possibility of new exploration drilling for
additional resources," commented Armando José Massucatto, General Manager of Exploration at Jaguar Mining.
“CEO Luis Albano Tondo commented: These drilling results at Faina confirm the continuity of high-grade
mineralization and reinforce our confidence in the resource growth potential at Turmalina. Equally important, the
initial metallurgical performance of Faina ore in the plant has so far exceeded our expectations, with gold
recoveries reaching approximately 70% in the industrial circuit, a meaningful improvement over the 55% observed
during previous lab and pilot testing. While these results are still preliminary and will require further monitoring to
confirm their consistency, they suggest that the Faina orebody could deliver stronger economic returns than
originally anticipated. Together, exploration success and encouraging metallurgical performance are advancing

Geological Overview
The Faina orebody is located within the Turmalina mine which also includes the A, B, and D orebodies, all hosted
within a NNW-trending shear zone that extends from the A orebody to the Pontal Norte orebody, indicating
connectivity of gold mineralization through well-understood shear zones.
The Faina orebody is a structurally controlled orogenic gold system that exhibits strong continuity of
mineralization along the interpreted mineralized trend. Gold mineralization is hosted predominantly within mafic
metavolcanic rocks affected by an extensive hydrothermal system. Mineralization occurs as disseminated sulfides
within shear zones and is primarily associated with fine-grained arsenopyrite, pyrrhotite, pyrite, and locally
antimony-bearing sulfide assemblages, reflecting a complex multiphase hydrothermal evolution.
The strong correlation between the planned drill targets and the assay results continues to validate the geological
interpretation of the deposit while refining the geometry and continuity of the mineralized lenses. These results
provide greater confidence for resource modeling, reduce geological uncertainty, and support more accurate
underground mine planning, stope design, and production sequencing.
Metallurgical Performance of Faina Ore in the Industrial Plant
During the initial processing of Faina ore at the MTL plant (part of the Turmalina mine complex) in June, gold

recoveries exceeded expectations, reaching approximately 70% in the industrial circuit , which represents a
significant improvement over the previously noticed 55% recovery observed in laboratory and pilot-scale testing.
This enhanced performance may be attributed to the more intensive pre-liming stage applied as part of the pre-
oxidation process in the industrial circuit, which appears to have a positive effect on the metallurgical response of
the Faina ore.
While these results are encouraging, they are based on a limited processing campaign and will continue to be
closely monitored over the coming months to confirm whether this improvement can be consolidated as the plant
gains further operational experience with the Faina ore feed. Additional metallurgical test work is also planned to
better understand the relationship between pre-oxidation conditions and gold recovery, supporting the
optimization of processing parameters for future production campaigns.
Future Work
Building on these encouraging initial results, the Company has commenced a new drilling campaign at the
Turmalina Mine Complex designed to continue advancing the definition of new Mineral Resources across the
orebodies located within the complex, including Faina. This next phase of drilling will target both the down-plunge
and along-strike extensions of the mineralized lenses identified to date, with the objective of further expanding the
resource base and supporting the full resumption of mining operations at the Faina orebody.
The campaign will also test additional priority targets within the Turmalina mine shear zone that remain
underexplored, leveraging the updated geological model to optimize drillhole placement and maximize discovery
potential. Results from this ongoing program will be released as they become available.
