Bravo Mining Corp. provided further assessment and details for its copper-gold exploration program at its 100% owned Luanga Project. This exploration focused on targets adjacent to, and beyond the limits of the Luanga palladium + platinum + rhodium + gold + nickel deposit, located in the Carajás Mineral Province, Pará State, Brazil.
A comprehensive Phase 1 exploration program is planned for 2026, integrating target refinement, advanced geophysics and drilling to systematically evaluate and prioritize copper-gold opportunities across the Luanga property, while also assessing potential for deeper extensions of known mineralization. Initial target refinement will include detailed geological mapping and expanded geochemical sampling (soil and rock). 50 line-km of deep-Induced Polarization survey coverage is planned across multiple priority targets.
Induced Polarization is an established method for targeting disseminated and stockwork sulfide mineralization, which constitutes the bulk of mineralization in IOCG/ISCG deposits, and has proven effective in the Carajás region. The survey is designed to investigate to depths exceeding 300m, beyond that of traditional Induced Polarization methods. Deep-Induced Polarization is also planned to cover portions of the Luanga deposit to evaluate potential for deep extensions, additional palladium + platinum + rhodium + gold + nickel mineralization, and potential ISCG/IOCG mineralization.
Additional geophysics, such as Time-Domain electromagnetic surveying, will be performed on targets with known mineralization such as T5 and T16 to seek potential continuations along strike or at depth of the high-grade mineralized shoots identified to date. An initial 8,000m drill program is planned for the second half of 2026 to test and prioritize the most prospective targets identified through earlier phases. Program to be extended based on results and interpretations.
Follow-up on previously reported copper-gold anomalism identified through trenching in the North Sector of the palladium + platinum + rhodium + gold + nickel deposit near the North?Central inflection zone and proximal to the Babylon target at the Luanga Deposit. Copper-gold exploration efforts will continue to focus on determining the relationship of the growing number of copper-gold-related mineralized occurrences in close proximity to the Luanga Deposit to a possible later copper-gold mineralizing event, or overprint, and its potential. In parallel with the copper-gold exploration, infill drilling is advancing as part of the ongoing work toward the completion of a Pre-Feasibility Study.
Ongoing evaluation of potential acquisition opportunities of copper-gold projects. Follow-up exploration of conductivity anomalies defined by an airborne helicopter Time-Domain electromagnetic and magnetic survey in 2023 has successfully identified several targets with copper-gold potential within the Luanga tenement. Testing of these targets resulted in the discovery of high-grade copper-gold +/- nickel mineralization in massive to brecciated sulfides in the T5 and T16 targets.
In addition to T5 and T16, several other copper-gold targets were defined and advanced with encouraging results to date. These targets had been initially interpreted by Bravo as belonging to the iron oxide copper-gold deposit type, which is characteristic of copper-gold mineralization in the Carajás Mineral Province. However, a recent review of the geological characteristics of the Luanga property indicates that the copper-gold mineralization outside the Luanga deposit can be classified as belonging to the Iron Sulphide Copper Gold deposit type, which is closely related deposit type to IOCGs and part of the broader copper?gold?iron mineral system.
ISCG and IOCG deposits share similar geochemistry, alteration, and paragenetic sequences, and commonly occur within the same geological provinces. A key distinction in ISCG systems is the absence of iron oxides (magnetite or hematite), which are replaced by iron sulfides, notably pyrrhotite and pyrite. ISGCs have also been described as containing more abundant quartz, which is a feature observed at several targets in the Luanga Property.
At T5 and T16, for example, quartz occurs as clasts in hydrothermal breccias that predate the main sulfide mineralization, which occurs in the matrix of the breccias in conjunction with altered rock fragments and other alteration minerals, but lacking magnetite. Similar quartz-sulfide breccias have been observed at other ISCG targets at Luanga, including Orion, Taurus, Lizard, and Gemini. The absence of magnetite in ISCG systems limits the effectiveness of magnetic methods for deposit identification, which are typically used in IOCG exploration.
A notable ISCG analogue deposit in the Carajás Mineral Province is the Antas Norte deposit, located approximately 40 km southwest of the Luanga tenement, which was discovered and mined by Avanco Resources. The Luanga project also demonstrates potential for more traditional IOCG mineralization. This potential includes areas adjacent to the Luanga deposit.
Examples include the Babylon target, where massive sulfide mineralization occurs near the top of a deeper hydrothermal alteration zone related to iron?calcium?potassium metasomatism, as well as in the North Sector, where trenching has returned elevated gold grades with associated copper, adjacent to metasomatized rocks. A Phase 1 exploration program has been designed to further define and test copper?gold targets in 2026. The program includes initial target refinement through geological mapping and additional geochemical sampling of soils and rock chips, followed by geophysical surveys and drilling.
A total of approximately 50 line-km of deep-Induced Polarization surveying is planned across multiple targets.
