Jaguar Mining Inc. Reports Encouraging Results at Chamé Target, Highlighting Potential for Open-Pittable Deposit in Brazil
Jaguar Mining (TSX:JAG) has announced encouraging exploration results from its Chamé target within the Paciência complex in Brazil's Iron Quadrangle. The company reported significant findings from three trenches, with highlights including 54.47 meters averaging 0.90 g/t gold, including 4.43 meters at 7.1 g/t Au in Trench TR02.
The exploration revealed broad, near-surface gold mineralization with potential true thicknesses ranging from 75 to 100 meters, suggesting potential for an open-pittable operation. The mineralized zone spans a 4-kilometer by 500-meter gold-in-soil anomaly. The target's strategic location near existing processing facilities could provide logistical and economic benefits for future development.
The company plans to accelerate exploration with a comprehensive drilling campaign later this year to better define and expand the mineralized zones.

TORONTO, ON / ACCESS Newswire / September 9, 2025 / Jaguar Mining Inc. ("Jaguar" or the "Company") (TSX:JAG) is pleased to announce encouraging results from its ongoing exploration program at the Chamé target. Chamé is located within the Company's Paciência complex, southeast of the Santa Isabel mine in Brazil's prolific Iron Quadrangle. These results highlight the presence of near-surface gold mineralization with potential for scale, which could represent an important step toward developing an open-pittable operation.
A SIGNIFICANT STEP TOWARDS OPEN-PITTABLE POTENTIAL
Since the Company's last update (see press release dated March 4, 2024), the exploration team has been advancing work along the Paciencia trend. This focused effort followed the identification of a notable gold-in-soil anomaly stretching four kilometers by 500 meters southeast of the Santa Isabel mine, within the highly prospective Chamé-Cedro trend. Building on encouraging initial rock sampling results and the new interpretations of advanced geophysical data suggesting near-surface mineralization, the Company initiated a targeted trenching program.
Results from the first three trenches (TR01, TR02, and TR03), excavated 100 meters apart and totaling over 428 meters in length, have returned consistent gold values across broad intervals. This suggests widespread gold mineralization rather than isolated occurrences (see Figure 1).
Highlights from the initial trenches include:
Trench TR02: 54.47 meters averaging 0.90 grams per tonne gold (g/t Au), including 4.43 meters at 7.1 g/t Au.
Trench TR01: 42.0 meters averaging 0.45 g/t Au and 33.0 meters averaging 0.31 g/t Au.
Trench TR03 : 20.51 meters averaging 0.21 g/t Au.
These encouraging results demonstrate broad, low-grade mineralized zones that also contain localized, high-grade intervals (see Figures 2 and 3). This pattern is commonly associated with large-scale gold deposits suitable for open-pit mining. Based on current interpretations, the potential mineralized zone is estimated to have true thicknesses ranging from approximately 75 to 100 meters.
STRATEGIC ADVANTAGE SUPPORTS GROWTH POTENTIAL
A key strategic advantage of the Chamé target is its location near the Company's existing processing facilities, which could provide important logistical and economic benefits and support a more efficient development path should the project advance to production. Combined with the widespread and consistent nature of the near-surface mineralization and the project's scale within a proven gold district, Chamé represents an attractive growth opportunity. Should further exploration confirm this potential, the target could become an important contributor to the Company's long-term growth.
ACCELERATED PATH FORWARD: DEFINING THE FUTURE
Building on these encouraging results, the Company is accelerating its exploration program at Chamé. A comprehensive drilling campaign is planned to begin later this year. This work will be important for better defining and expanding the mineralized zones, helping to systematically evaluate the project's potential and informing future development planning.
Luis Albano Tondo, Chief Executive Officer of Jaguar Mining, commented: "The results at Chamé represent an important step for Jaguar. The consistent, broad gold mineralization observed to date highlights the potential for an open-pittable deposit, complementing our existing high-grade underground operations. Its proximity to our processing facilities further underscores the project's strategic value and potential to become an important asset for the Company. We are excited about the opportunity to define a new, large-scale gold deposit in the heart of the Iron Quadrangle."
Armando Massucatto, Exploration Manager for Jaguar Mining, added: "Chamé represents an important development in our understanding of gold mineralization along the São Vicente Lineament. What was once interpreted primarily as narrow vein systems is now recognized as broader, potentially high-volume gold deposits with significant disseminated mineralization. These results provide new prospects for major discoveries in the Paciência area, reinforcing its importance as a key exploration frontier for the Company and highlighting the skill and dedication of our exploration team."
A WORLD-CLASS GOLD PROVINCE
The Chamé target is located within the São Vicente Lineament, a renowned gold-rich region within Brazil's prolific Iron Quadrangle (see Figure 4). This geological structure has historically hosted world-class, multi-million-ounce gold mines, including the Morro Velho mine operated by Anglo Gold Ashanti, which produced approximately 11 million ounces of gold. This lineament represents a major mineralized crustal shear zone extending for at least 60 kilometers, with a proven history of significant gold deposits.
Jaguar is well-positioned in this highly prospective area, holding the second-largest gold land position in the Iron Quadrangle, covering over 46,000 hectares. Ongoing exploration at Chamé continues to support the potential for meaningful new gold discoveries in this historically significant mining area (see Figure 5).
The trenching program returned continuous gold values above 0.4 g/t Au across most of the channel samples from TR01 and TR02. These results highlight the presence of broad, low-grade mineralized zones, with localized high-grade intervals, interpreted as feeder structures, yielding values above 1.5 g/t Au (see Figure 1).
Trench TR01
CMCH01: 8.0m @ 0.33 g/t Au
CMCH02: 42.0m @ 0.45 g/t Au, including 25.0m @ 0.56 g/t Au and 6.0m @ 0.93 g/t Au
CMCH03: 33.0m @ 0.31 g/t Au, including 6.0m @ 0.52 g/t Au
Trench TR02
CMCH05: 54.47m @ 0.90 g/t Au, including 32.22m @ 1.29 g/t Au and 4.43m @ 7.1 g/t Au
CMCH06: 24.78m @ 0.41 g/t Au, including: 11.39m @ 0.50 g/t Au and 12.94m @ 0.52 g/t Au
Trench TR03
CMCH008: 0.49m @ 0.21 g/t Au
CMCH011: 8.40m @ 0.28 g/t Au
CMCH012: 13.36m @ 0.20 g/t Au; and 20.51m @ 0.21 g/t Au
Note: the thicknesses indicated for the channels are apparent. In sections TR01 and TR02 (see Figures 2 and 3), it can be observed that the estimated true thickness for the mineralized zone ranges between 75 and 100 meters.

The Iron Quadrangle
The Iron Quadrangle has been an area of mineral exploration dating back to the 16th century. The discovery in 1699-1701 of gold contaminated with iron and platinum-group metals in the southeastern corner of the Iron Quadrangle gave rise to the name of the town Ouro Preto (Black Gold). The Iron Quadrangle contains world-class multi-million-ounce gold deposits such as Morro Velho, Cuiabá, and São Bento. Jaguar holds the second largest gold land position in the Iron Quadrangle with over 46,000 hectares.
