Jaguar Mining Inc. Provides Update on Geologic Interpretation at the Chame Target, Part of the Company's CPA Project in Minas Gerais, Brazil Jaguar Mining Inc. provided an update on its ongoing exploration program at its Chame target, part of the Company's CPA Project in Minas Gerais, Brazil. The exploration program at this priority target aims to delineate and expand known gold mineralization within a highly prospective geological corridor, located approximately 3km to the southeast of Jaguar's CPA Complex (which hosts the Santa Isabel Mine, slated to reopen in 2026, and processing plant, currently on care and maintenance). The results to date reinforce the view that Chame remains a highly prospective target area, and the company is focused on executing the 2026 program in a disciplined, data-driven manner. To date, the Company has completed five diamond drill holes (FCM001 through FCM005) at the Chame target, totaling 1,531.85 meters. Assay results for the first two holes are discussed in this press release, with the samples from the remaining holes still in the assay process. Holes FCM003 to FCM005, accounted for 939.55 meters of this total (awaiting results). This drilling focused on sampling the historic system of trenches throughout the Chame area, excavated by the early explorers in the 1700s, who pursued high grade gold veins as deep as their primitive technology would allow. Jaguar's trench sampling results were encouraging in terms of near-surface gold mineralization, leading the Company to make Chame a priority target for additional exploration. The prospectivity of the area, and its proximity to the CPA Complex (Santa Isabel Mine), satisfied the criteria of the exploration strategy of delineating additional mineralization as close to the Company's mining complexes as possible. Initial assay results have been received for the first two holes. Drill hole FCM001 intersected 15.35 meters grading 0.44 g/t Au, and drill hole FCM002 returned 4.09 meters grading 0.33 g/t Au. While these initial results confirmed wide-spread gold mineralization, they did not reproduce the higher-grade gold values previously observed in surface trench TR02. Historical drilling was conducted at the Chame target area by the Morro Velho mining company in 1988, focusing on the Santa Isabel shear zone-hosted gold structure. While these historical results indicate significant gold mineralization, they are not compliant with current NI 43-101 standards due to the unavailability of the original drill cores for verification. To validate these historical findings and support future resource-style work, Jaguar plans to execute a series of twin holes and carry out additional drilling to support the geological continuity of Santa Isabel trend structure along the Chame target area. This verification drilling is a critical step in integrating historical data into the Company's current exploration efforts. Geological Interpretation and Exploration Potential. Future Work at Chame. Jaguar remains optimistic about the potential of the Chame target and has outlined the following immediate next steps for the exploration program: Further Drilling: An additional 1,000 meters of drilling is planned to continue evaluating the Chame target gold trend structure. And additional drilling of one hole, FCM005, is designed to evaluate drill-spacing strategy and test the central portions of interpreted boudinaged mineralized bodies related to its down plunge direction and dimensions. Step-Out Drilling: Potential 25-50-meter step-out holes are being considered based on the geological interpretation of FCM003 and FCM004. Twin Hole Program: Execution of twin holes to verify historical Morro Velho drilling results. Gap Investigation: Initial exploration work to investigate the 840-meter prospective gap between Chame and Santa Isabel. Targeting Refinement: Ongoing refinement of the geological model and targeting strategy based on new data. Drill holes. Note: For the trenches, results were compiled using apparent thickness due to the terrain slope; however, the drillholes intersected the rock units nearly perpendicular to the local foliation/bedding, so the reported thickness is considered a true width. Samples were submitted to SGS-Geosol Laboratories Ltd, Vespasiano, Minas Gerais, Minas Gerais. Announcement • Jan 08
Jaguar Mining Inc. Announces Approval from ANM for Resumption of Key Operations At its MTL Complex, Powering Future Growth with Safety & Excellence Jaguar Mining Inc. announced the official approval from the National Mining Agency ("ANM") for the restart of key mining and processing operations at the Company's MTL Complex. This decision marks a significant event in the progress of the Company toward its planned gold production levels, allowing for the resumption of crucial operations, including underground development, underground mining, and the full function of the metallurgical plant, paste fill plant, and filtration unit. As highlighted by the ANM's decision, this approval enables the execution of Stages 3, 4, and 5 of Jaguar's Gradual Resumption Plan. The Satinoco dry-stacked pile incident, which led to the temporary suspension of operations, has been effectively removed from service, with no additional material to be placed on that stack. Demonstrating the Company's proactive approach and unwavering commitment to the future, Jaguar commissioned a new, state-of- the-art tailings facility recently, now fully ready to support the revitalized operations at the MTL Complex. The actual resumption of operations is now conditional upon a final clearance from the Environmental Emergency Office (NEA). The NEA is independent from ANM and is exclusively responsible for overseeing environmental matters. The lifting of the NEA embargo order is subject to the NEA's review of the ANM's decision to allow operations at MTL to resume. Immediately upon receipt of the ANM decision, Jaguar submitted this decision to NEA. Jaguar now awaits acknowledgement from NEA so that operations at MTL mining complex may resume.
