Bravo Mining expands metallurgical results and workstream update

Canada NewsWire

TORONTO , Aug. 11, 2026 /CNW/ -- Bravo Mining Corp. (TSXV: BRVO) (OTCQX: BRVMF), (" Bravo " or the " Company ") is pleased to report additional encouraging metallurgical results from the application of Jameson Cell technology to its 100% owned Luanga palladium + platinum + rhodium + gold + nickel deposit (" Luanga deposit " or " Luanga PGM+Au+Ni deposit "), located in the Carajás, Brazil.

Following the earlier investigations relating to the application of Jameson Cell technology to the beneficiation of the mineral products from the Luanga deposit (see press release dated January 12, 2026 ), Bravo has continued to make progress in advancing the application of this widely-used technology to its Luanga deposit and establishing it as the preferred flotation route for the upcoming Pre-Feasibility Study ("PFS").

The program is focused on enhancing metals recovery, improving rougher concentrate grades, and optimising the overall process flowsheet.

Metallurgical work, using Jameson Cells, continues with both bench-scale testing and pilot scale tests, while also seeking to optimise reagent consumption, economise on circuit configurations, equipment sizing, and other process parameters.

Highlights include:

The application of Jameson Cell technology has continued to demonstrate improved flotation performance over the use of traditional flotation cells.

A comprehensive rougher-stage flotation program has been completed, with results further supporting the adoption of Jameson Cell technology not only in the rougher stage but also in the cleaner flotation circuit. Final tests are underway, with results expected in the coming weeks in support of the upcoming PFS.

Current Jameson Cell testing reaffirmed a potential 5-10% improvement in Pt, Pd and Au recoveries and 5-30% higher Ni recoveries vs. conventional Denver cells, while achieving up to 50% lower mass pull with no material loss in recovery as compared to conventional flotation cells.

Inclusion of Jameson Cells in both rougher and cleaner applications enhance selectivity and has demonstrated potential to raise achievable concentrate grades from historic 80g/t to 100-120g/t PGMs (a 25%-50% improvement).

Higher concentrate grades have the potential to improve payabilities, reduce freight and decrease treatment charges.

Jameson Cell technology is widely employed globally, including within PGM flotation plants in Southern Africa where recoveries/concentrate grades have improved using the technology, and reduced CAPEX & OPEX have been reported.

"We are very pleased with the results from our Jameson Cell testing, which continue to demonstrate improved metal recoveries and higher concentrate grades, while achieving significantly lower mass pull compared with conventional flotation cells. We expect these improvements to positively contribute to the Luanga PFS and, importantly, may further enhance the 'Vertically Integrated' project scenario being evaluated alongside the 'concentrate' scenario planned for inclusion in the PFS," said Luis Azevedo, Chairman and CEO. "We also appreciate the strong technical support from Glencore Technology as we advance the flotation program. Their indicated willingness to provide performance guarantees based on their review of the Luanga metallurgical data provides further confidence in the application of Jameson Cell technology to the project.

With the PFS now approaching completion, we remain on track for delivery in Q3 2026, followed by the Installation Licence application. Our ongoing PGM infill and expansion drill program is also expected to be completed during Q3, with results supporting an updated Mineral Resource Estimate targeted for Q1 2027 and the Definitive Feasibility Study targeted for Q3 2027. In parallel, we are preparing to commence our copper-gold drilling program by early Q4."

THE JAMESON CELL TECHNOLOGY

The Jameson Cell technology has been in service around the world for over 30 years, with over 500 units in operation today across 30 countries. Perhaps its most best-known application was reported at the world class Mt Isa Copper Mine in Australia, where it was developed for its superior performance over traditional flotation cells in the recovery of fine mineral particle sizes not unlike that hosted by Luanga. The improved performance is attributed to the better bubble-particle environment within the Jameson Cell.

Preliminary Expanded Metallurgical Test Work Results

Results reported herein include rougher flotation and preliminary Jameson cleaner test results incorporating Glencore Technology's standardised Jameson simulation test protocol. The program is ongoing and will include additional cleaner stage optimisation and pilot scale tests.

The purpose of the expanded program is to further confirm, with greater confidence, previously recorded results from the initial exploratory Jameson program completed earlier this year and reported in the January 12, 2026 news release. The objective is to generate metallurgical data that will support Pre-Feasibility Study requirements and to investigate opportunities for optimisation around the flotation process.

As previously reported, the Company identified an opportunity to further improve metallurgical performance by targeting incremental recoveries from losses of fine-grained mineralisation reporting to final tailings when using conventional flotation cells. To this end, the Jameson flotation cell technology has been evaluated by applying multiple tests on differing samples conducted independently at Base Metallurgical Laboratories Ltd. (Intertek), in Kamloops, BC, Canada.

The Jameson Cell rougher tests were conducted at laboratory-scale to Glencore Technology's standardised 3-stage dilution test.

Testing included composite samples from the North sector grading 1.97g/t Pd + Pt + Rh + Au ("4E PGM"), 0.21% Ni to 2.80g/t 4E PGM, 0.21% Ni. The primary grind size selected was 80% passing (P80) 28µm. Operating conditions were controlled to optimise the Jameson Cell air bubble mixing intensity, including stable air entrainment, feed density and froth washing.

Figures 1 and 2 show that, the recent Jameson tests (the JAMROUGH curve) demonstrated and reaffirm apparent improvements (over conventional Denver cells) in recovery of 5 - 10% for platinum, palladium and gold.

Moreover, positive results were again observed for nickel recoveries, with a 5 - 30% improvement across the recovery-mass pull curve. This outcome was achieved coincident with up to 50% reduction in mass pull with no material loss in recovery which is highly desirable and very encouraging for future upside.

Preliminary Cleaner Test

Cleaner tests have since validated the flotation performance, delivering marginally improved metal recoveries while confirmed the higher concentrate grades. These results indicate that (as yet unoptimized) Jameson Cell cleaner tests have also outperformed conventional cells in cleaning functions. This is evident from the diagram below (Figure 3), where the Jameson Cells produced a 120 g/t concentrate at a notably higher recovery that the corresponding Dever cell baseline test.

Future work will seek to optimise the application of Jameson Cell technology to the cleaning duties targeting potential further improvements.

The Jameson Cell technology is characterised by a direct 1:1 scale-up from laboratory cells to full-scale commercial installations, providing a high degree of confidence that lab performance is representative of what can be expected at industrial scale.

Accordingly, the Jameson Cell results are considered a reliable indication of result in commercial processing flowsheet and are accepted as being sufficiently reliable for inclusion in Bravo's PFS/DFS studies

Continued Program

Similar tests have been conducted on the Central and Southwest sector material from Luanga with results pending.

Due to the low mass pull achieved, sector-by-sector cleaner tests will subsequently be conducted on composited rougher products obtained from the 3-stage dilution tests.

Further locked cycle tests, simulations and pilot scale L150 tests will be conducted subsequently, incorporating the optimised parameters and circuit configuration established from the 3-stage dilution tests.

Glencore Technology Independent Review and Technical Support

As part of Bravo's technical assurance, the Company has been working in close partnership with the Jameson Cell technology provider, Glencore Technology, to advance and support the ongoing program. This includes members of Glencore's team in Brazil, Cananda and Australia.

In support of the ongoing PFS work, Glencore was asked to independently review all historical and currently generated metallurgical data from the Luanga project. The data included previous conventional flotation test data, locked cycle test data, circuit design and mass balance data, and all recently generated Jameson-related data.

The review provided a further independent verification process on the metallurgical performance assumptions for the Luanga project with reference to how the data and performance assumptions relate and translate into the Jameson Cell environment.

Following the review, Glencore Technology has concluded that it is prepared to issue performance guarantees on the metallurgical performance assumptions based on the current Luanga metallurgical database while confirming the expectation that performance can be further improved with the adoption of the Jameson Cell technology.

Glencore is providing further technical support in test program guidance, simulations and mass balance determinations while providing design support for the PFS.

Metallurgy Program Next Steps

Bravo will continue its metallurgical test work program, with a focus on validating Jameson Cell performance through additional testing and assessing its integration into the Luanga flowsheet.

Testing will include further rougher trials and exercises wherein Jameson Cells are used instead of traditional cells in the cleaner circuit. This will then be complemented by lock-cycle testing of various rougher-cleaner circuit configuration.

Upon completion of this work, representative samples from the Luanga Central and Southwest Sectors will be tested using Jameson Cells to ensure suitability across the deposit.

Pre-Feasibility Study Update and Next Milestones

The Pre-Feasibility Study is on track for completion by Q3 this year with the substantial components of the study already completed, including the updated project general arrangement, mining studies, optimisation and designs, and plant and infrastructure engineering disciplines. Currently, capital cost estimates and operating costs are in finalisation with conclusion of the economic evaluation anticipated in coming weeks.

As Bravo advances toward completion of the Pre-Feasibility Study, several key workstreams are continuing in parallel. On completion of the current PGM drilling program, the Company's drill rigs will transition to the recently established Copper-Gold Division (see news release dated February 5, 2026 ), which is expected to commence its drilling program by early Q4 2026.

Following completion of the PFS, Bravo intends to advance the permitting process through submission of the Installation Licence ("LI") application. Results from the 2026 PGM drilling program, expected to be completed in Q3 2026, will support an updated Mineral Resource Estimate ("MRE") targeted for Q1 2027. The updated MRE will form the basis of the Company's Definitive Feasibility Study ("DFS"), currently targeted for completion in second half of 2027.
