- 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."
"The strategic objective of the 5-year exploration plan Jaguar announced in late 2025 is to fully and systematically explore the high-priority targets among the +400 mineralized occurrences within the 46,000 hectares of mineral tenements held by Jaguar Mining in the Iron Quadrangle," commented Jaguar Mining CEO Luis Albano Tondo. "The goal of this program is to identify mineral resources which can be developed into mineral reserves, ultimately increasing the total gold production for the Company."
Drilling at the Chamé target intercepted low-grade structures within the hanging wall, while the footwall continues to host the higher-grade mineralization characteristic of the Santa Isabel/Marzagão system. These results allow the Company to track the southeast continuity of the mine's mineralized structure over 1 kilometer beyond current Santa Isabel underground mine workings.
The Paciencia Trend is part of the broader São Vicente lineament regional trend on which sits the world class Morro Velho gold mine (now closed) which produced over 10 million ounces of gold during its years of operation by Anglo Gold Ashanti (1834 to 2004).

Figure 3: Longitudinal section looking Northeast showing key results from the drilling campaign. In green, the modeled structure based on recent results correlates with the mineralized structure hosting the Santa Isabel/Mazargão mine (visible in brown on the right portion of the figure, footwall). The green structure represents the hanging wall containing the lower-grade mineralization at Chamé.
When comparing these results with historical data from the Bahú target (refer to the technical report available on SEDAR+ entitled "NI 43-101 Technical Report, Caeté Mining Complex, Minas Gerais, Brazil", with an effective date of December 31, 2025), there is a clear similarity in gold mineralization structures. The presence of multiple sub-parallel mineralized bodies suggests a robust system of stacked structures.
Figure 4: Type section of the Bahú target showing low-grade halos with high-grade cores (as indicated in the composites). Note the significant down-dip continuity of mineralization.
The dual-structure nature of the Chamé target is attributed to the São Vicente lineament, which functions as an anastomosing shear zone with multiple branching splays. While surface continuity is evidenced by colonial-era (1700s) workings, Jaguar's systematic mapping and sampling is identifying new structures that indicate high potential for additional medium-to-low grade gold mineralization which could lead to open pit potential.
The confirmed continuity of these structures through drilling indicates a structurally controlled mineralized system active along the 15 kilometers of mapped trends within Jaguar Mining's tenements. This positions the entire area as a premier exploration district with significant Tier 1 district-scale gold potential.

Mineral Resource at Paciencia
Paciencia, which includes the Santa Isabel-Marzagão structure, has current underground Inferred Mineral Resources of 189,000 ounces of gold across 1,423,000 tonnes at a weighted average grade of 4.14 g/t Au. Jaguar is currently preparing the Santa Isabel mine for potential reopening by the end of 2026 with dewatering, underground rehabilitation, underground drift development, and an underground diamond drilling program to be followed by a formal technical report.
Sampling and QA/QC
Drill core samples were collected under the supervision of Jaguar Mining's geological staff. Samples were submitted to SGS-Geosol Laboratories Ltd and ALS Global Laboratories, Vespasiano, Minas Gerais, Brazil, both independent, accredited laboratories, for analysis. Gold assays were performed using FAA525, Au-AA26 and ME-MS61 analytical process - fire assay with atomic absorption finish. A comprehensive Quality Assurance/Quality Control (QA/QC) program involving the insertion of certified reference materials, blanks, and duplicates was implemented to monitor the integrity of the assay results. All structural measures were collected using the v-Star method supported by the Ore. Node structural geology software.
About the Iron Quadrangle (Quadrilátero Ferrífero)
The Paciencia Gold District (which include the targets mentioned in this press release) is located in the Iron Quadrangle, a world-class, prolific greenstone belt in the state of Minas Gerais, Brazil. This region is renowned for its significant iron and gold deposits, hosted within Archean and Paleoproterozoic stratigraphic sequences. Jaguar's strategic land package in this district continues to offer substantial exploration upside.
