Bravo Mining Advances Jameson Cell Test Work as Luanga PFS Nears Completion

• Jameson Cell testing reaffirmed a 5 to 10% improvement in platinum, palladium and gold recoveries, along with a 5 to 30% improvement in nickel recoveries, compared with conventional flotation cells
• The technology achieved up to 50% lower mass pull, the proportion of ore reporting to concentrate, with no material loss in recovery
• Preliminary cleaner tests raised achievable concentrate grades from a historic 80 grams per tonne to 100 to 120 grams per tonne, a 25 to 50% improvement
• Glencore Technology, the developer of the Jameson Cell, has indicated it is prepared to issue performance guarantees based on its review of Luanga's metallurgical database
• The Pre-Feasibility Study remains on track for Q3 2026, with an updated Mineral Resource Estimate targeted for Q1 2027 and a Definitive Feasibility Study targeted for the second half of 2027

Bravo Mining Corp. (TSXV: BRVO) (OTCQX: BRVMF) is a Canada and Brazil-based mineral exploration and development company advancing its Luanga project in the Carajás Mineral Province of Para State, Brazil. Luanga hosts platinum group metals, nickel, and a copper-gold opportunity, and Bravo has built a track record in the region through a team of local and international geologists with prior experience taking a project from discovery through to production in Carajás. The project sits on established farmland with access to nearby infrastructure, including road, rail, and hydroelectric grid power, and the Company has also planted more than 55,000 trees as part of its environmental and community programme.

Jameson Cell Technology Demonstrating 5 to 10% PGM Recovery Improvement and Up to 50% Lower Mass Pull

Bravo has continued testing the Jameson Cell, a flotation technology that separates valuable minerals from waste rock using air bubbles in a tank, as a potential replacement for the conventional flotation cells historically used at Luanga. The latest results build on an initial test programme reported in January 2026 and now include a completed rougher stage flotation programme, the first step in separating valuable minerals from ore, together with preliminary cleaner stage testing, which refines the rougher concentrate to a higher grade.

The current results reaffirmed the 5 to 10% improvement in platinum, palladium and gold recoveries and the 5 to 30% improvement in nickel recoveries referenced above, measured against Bravo's conventional flotation cells. These outcomes were recorded alongside up to 50% lower mass pull. Cleaner stage testing has also lifted achievable concentrate grades from a historic 80 grams per tonne to a range of 100 to 120 grams per tonne. According to the release, higher concentrate grades have the potential to improve payability, the price received for the material, and to reduce freight and treatment charges. Further cleaner stage optimisation and pilot scale testing are ongoing, with additional results expected in the coming weeks.

The Jameson Cell scales directly from laboratory to commercial installations at a 1:1 ratio, which the Company states provides a basis for expecting laboratory results to be representative of full scale performance. The technology has been in commercial use for more than 30 years, with over 500 units operating across 30 countries, including PGM flotation plants in Southern Africa.

Glencore Technology Prepared to Issue Performance Guarantees Supporting Luanga PFS Completion in Q3 2026

The Jameson Cell is supplied by Glencore Technology, which has worked alongside Bravo's team in Brazil, Canada and Australia to support the testing programme. As part of this work, Glencore Technology was asked to independently review Bravo's full metallurgical database for Luanga, spanning historical conventional flotation results, circuit design data, and the Jameson Cell results generated to date.

Following that review, Glencore Technology concluded it is prepared to issue performance guarantees on the metallurgical assumptions underpinning the Luanga project, based on the current database. Glencore Technology also indicated that performance could improve further as the test programme continues, and is providing additional technical support, including guidance on test programme design, simulations, and mass balance work, along with design input for the Pre-Feasibility Study.

Bravo Chairman and CEO Luis Azevedo said:

"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. 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."

Updated MRE Targeted Q1 2027 and DFS Targeted H2 2027 Following Completion of PGM Drilling Program

Substantial components of the Pre-Feasibility Study have been completed, including the project's general arrangement, mining studies, and plant and infrastructure engineering. Capital and operating cost estimates are being finalised, with the economic evaluation expected to conclude in the coming weeks ahead of the targeted Q3 2026 completion.

Bravo's PGM infill and expansion drilling programme is expected to conclude in the same quarter. Results from that programme are intended to support an updated Mineral Resource Estimate, targeted for the first quarter of 2027, which will form the basis for a Definitive Feasibility Study targeted for the second half of 2027.

Once the current PGM drilling programme concludes, Bravo's drill rigs are expected to transition to the Company's Copper-Gold Division, with that programme expected to begin by early Q4 2026. Following completion of the PFS, Bravo intends to submit an Installation Licence application, a step in Brazil's environmental permitting process.

Milestones and Next Steps

Bravo has several catalysts scheduled over the coming months. Additional cleaner stage and pilot scale test results are expected in the coming weeks, alongside similar test work underway on the Central and Southwest sectors of the Luanga deposit. The Pre-Feasibility Study remains on track for completion in the third quarter of 2026, to be followed by the Installation Licence application. The current PGM drilling programme is expected to conclude in the third quarter, with copper-gold drilling scheduled to begin by early in the fourth quarter. The updated Mineral Resource Estimate is targeted for the first quarter of 2027, and the Definitive Feasibility Study is targeted for the second half of 2027.
