TORONTO, Ontario — January 12, 2026 — Leads & Copy — Bravo Mining Corp. (TSXV: BRVO) (OTCQX: BRVMF) has announced encouraging results from metallurgical test work using Jameson Cell technology at its Luanga palladium + platinum + rhodium + gold + nickel deposit in Brazil.
The test work, part of an ongoing optimization and metallurgical development program, aims to enhance metal recovery and improve selectivity. It supports the ongoing Pre-Feasibility Study (PFS).
Jameson Cell testing showed improved recovery-to-mass pull performance compared to traditional rougher flotation. PGM recoveries improved by 5-10%, and nickel improved by 5-30% above baseline conventional cell recoveries, while mass pull reduced by up to 50%.
The results suggest the potential for lower mass pull and enhanced selectivity, which could lead to higher concentrate grades and lower concentrate tonnage for the same payable metal. This could positively impact future concentrate payabilities and operating costs.
Nickel recoveries also showed potential to improve future Luanga concentrate value and project economics. Improved rougher stage recovery was observed across the Luanga mineralisation metals suite of platinum group metals (PGM), nickel and gold.
Jameson Cell technology is widely used globally, including in PGM operations in southern Africa. It has reportedly led to improved recoveries and concentrate grades, as well as reductions in capital and operating expenditures.
The technology will be trialled in subsequent cleaner and scavenger circuit configurations and on samples from additional mineralized zones.
Chairman and CEO Luis Azevedo stated the preliminary Jameson Cell results reinforce the technical optionality available to Bravo. He added that incremental recovery improvements at higher concentrate grades would benefit potential future flotation plant economics and downstream processing efficiencies.
Azevedo also noted the Jameson Cell’s success in large-scale mines like Valterra’s Mogalakwena PGM mine. He believes its application to Luanga’s potential 10Mtpa run-of-mine is technically supportable and appropriate.
Initial results demonstrate that the Jameson Cell achieved improved metal recoveries at significantly reduced mass pull when benchmarked against traditional flotation (conventional) cells. The improved performance is attributed to the better air bubble/mineral contact environment created within the Jameson Cell environment.
The company identified an opportunity to further improve metallurgical performance by targeting incremental recoveries from losses of fine-grained mineralisation reporting to final tailings. Tests were conducted at Base Metal Laboratories in Kamloops, BC, Canada.
The Jameson Cell rougher test results plot favorably on the recovery versus mass pull curve when compared with conventional cell rougher tests. Higher recoveries were recorded with a significantly reduced mass pull, translating to the production of a higher-grade concentrate.
While management cautions that results are preliminary, they are considered significant given their apparent improvement compared with historical values. Jameson technology could also produce further upsides, including reduced circulating loads, simplified rougher-cleaning stages and improved overall flotation efficiency.
The Jameson test was conducted as a laboratory-scale rougher flotation exercise using a Jameson L150 cell on a 20kg representative, homogenised, sulphide composite from the North Zone, with PGM grades in the test samples ranging from 1.97g/t Pd + Pt + Rh + Au (“4E PGM”), 0.21% Ni to 2.80g/t 4E PGM, 0.21% Ni. The sample was prepared to target a primary grind size of approximately P80 (29µm).
To establish the base line for comparison, a conventional sulphide reagent suite, including PE26 depressant and PAX collector was used to replicate historical parameters. 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 relative to the comparative baseline assessment data, the Jameson test demonstrated apparent improvements in recovery of 5 – 10% for platinum, palladium and gold. Similarly positive results were reported for nickel recoveries, with a 5 – 30% improvement across the recovery-mass pull curve vs the conventional cells.
Furthermore, this outcome was achieved coincident with a 50% reduction in mass pull, at similar recovery assessment points on the recovery-mass pull curve, which suggest overall higher final concentrate grades may be achieved.
Importantly, Jameson Cell technology is reportedly characterised by a direct 1:1 scale-up from laboratory cells to full-scale commercial installations, providing a high degree of confidence that performance observed under lab conditions is likely representative of what should be expected in an industrial scale application.
Previous mineralogical investigations of the Luanga mineralization have determined that a component of the platinum group minerals occurs within a fine size fraction. The collection and flotation kinetics in Jameson cells has been demonstrated to be effective at further improving recovery of minerals in fine fractions, while significantly reducing mass pull, thus further improving the selectivity and concentrate grade.
Jameson Cells are increasingly utilised in platinum group metal circuits, where fine particle recovery and selectivity is important. Key advantages of Jameson Cell technology are reported to include: High recovery across a wide particle size range, Feed to concentrate conversion (mass pull) reduction, Reduced footprint and simplified circuit design, Lower capital and operating costs, and Proven scalability.
Bravo will continue its metallurgical test work program, focusing on validating Jameson Cell performance through additional testing and assessing its integration into the Luanga flowsheet. Samples from the Luanga Central and Southwest Sectors will also be examined using Jameson Cells to ensure suitability across the whole deposit. Results from this programme are expected to provide new and important contributions for current
