VANCOUVER, BC, May 8, 2023 /CNW/ - Bravo Mining Corp. (TSXV: BRVO) (OTCQX: BRVMF) ("Bravo" or the "Company") announced that it has received assay results from five trenches and four previously unsampled large diameter ("ZW") historical metallurgical drill holes, all located in the Southwest sector of its 100% owned Luanga palladium + platinum + rhodium + gold + nickel project ("Luanga" or "Luanga PGM+Au+Ni Project"), located in the Carajás Mineral Province, state of Pará, Brazil.

"Initial trenching shows potential for increased thickness and supergene enrichment, warranting an expanded trenching program at Luanga", said Luis Azevedo, Chairman and CEO of Bravo. "In addition, the receipt of assay results from the large diameter metallurgical drill core that had not been sampled by the previous owner has provided valuable localized grade and geological information and, more importantly, tonnes of mineralized material, both oxide and fresh rock, that is immediately available for Phase 2 metallurgical program and/or later pilot scale test work."

Highlights Include:

• Trenching trialed in the Southwest Sector successfully defined thicker zones of mineralization at surface in comparison to nearest neighbour drill holes below the trench, while assay results indicate grade enrichment in most cases.
• Historical drill core received at site includes large diameter ZW metallurgical core (165mm) drilled in the Southwest Sector that had not been previously sampled. Assay results from channel sampling of this core are as good or better than nearby drill holes, supporting Bravo's interpretation of geology and mineralization. The core is now ready for use in the Phase 2 metallurgical program.
• The combinations of trenching, assay results from the ZW metallurgical core re-sampling and re-logging have improved interpreted mineralization in these areas (see Figures 2a and 2b).

Luanga Trenching Program

A trial program testing the effectiveness of trenching commenced at Luanga's Southwest Sector (Figure 1) in 2022. Trenching across the strike of the outcrop/sub-crop aimed to accurately map mineralization at surface to enable better interpretation for the planned Mineral Resource Estimate ("MRE"), and to reduce the distance/spacing between assay data points in preparation for later MRE classification (i.e., Indicated/Inferred). Trenching also provides detailed outcrop mapping, supporting interpretation of the near surface at Luanga.

The trenching program has also highlighted the increase in mineralized thickness intersected in shallow drillholes nearby. Assay results from trenching (Figures 2, 3, & 4) clearly show that mineralization in the saprolite zone (above the base of oxidation) increases in thickness, common in tropical weathering profiles. Figure 7 shows mineralized thicknesses in plan. In addition, the PGM grades in the trench samples compare favourably to the high-grade intersections in nearby down dip drillholes (Figures 2 & 3). This further suggests supergene enrichment in the saprolite zone.

Luanga Metallurgical Drill Core

Historical ZW core (165mm diameter core from a 192mm diameter drill hole) (Figure 5) has been received by Bravo for four holes in the Southwest Sector (Figure 6). This core was initially intended for bulk sampling metallurgical test work by the previous owner but was not previously sampled. Bravo has relogged the core, located and verified the locations of these drill holes, and received assay results from its channel sampling of the core. Sampling procedures followed the same methodology (cutting core to both regolith and lithological contacts) and QAQC procedures used on the Company's own drill core. These historical ZW holes were drilled to cover a range of mineralization locations across the Southwest Sector, as shown in Figure 6. The core is to be used in the Phase 2 metallurgical program.

Two versions of the same drill section are shown below (Figure 2a & 2b). Figure 2a is the current version, with a trench form drill holes PPT-LUAN-FD0020 to PPT-LUAN-FM0004, with the extended zone of mineralization and high grades at surface. Trench assay grades are also superior to assay grades in nearest neighbour drilling below the trench, supportive of supergene enrichment. Figure 2b shows the original historical interpretation of the same section, without the benefit of new data. See notes on the sections for details of key changes.

Figure 3 shows a longer trench excavated to completely cover the potential thickness of mineralization at surface, where both the southern and northern limits to mineralization had not been defined by drilling. Trenching now provides a factual basis for interpretation, showing that mineralization merges in the saprolite zone to produce a continuous 146m thick layer of mineralized interval at surface. Again, assay grades encountered in trenching are higher than assay grades in nearest drill holes below the trench, supporting the existence of supergene enrichment.

Whereas the saprolite zone is relatively thin (ranging from <2m on the ridge line, to 25m away from the ridge), given Luanga's 8.1km of strike, the presence of similar saprolite layer +/- secondary enrichment could result in the definition of a significant volume of saprolite zone/oxide mineralization in a future MRE.

Trenching, performed to a high quality, replaces the requirement for the many shallow drill holes that would be needed to achieve the same result for the coming Phase 1 MRE. The same sampling, assay laboratory procedures and QAQC protocols as applied to drill core sampling are applied to trench samples.

Given the encouraging results from trenching to date, trenching is planned to continue in 2023 along the entire 8.1km strike length of the Luanga deposit.

Figure 4 shows how trenching to the south of metallurgical drill hole PPT-LUAN-FM0004 has defined the southern limit to mineralization at surface. Previously this was interpreted more conservatively. Trench data provides a factual basis for interpretation, with mineralization extending far closer to drill hole PPT-LUAN-FD0019. Sampling of ZW core metallurgical drill hole PPT-LUAN-FM0004 again shows the excellent continuity of mineralization.

Figure 6 shows a surface plan of the 5 trenches completed to date in the Southwest Sector. Thick magenta-coloured stripes show the thickness of mineralization at surface in the trenches.

Luanga Drilling Status

A total of 175 drill holes (40 in 2023) have been completed by Bravo to date, for 31,510 metres, including all 8 planned twin holes and all 8 metallurgical holes (not subject to routine assaying). These 8 metallurgical holes are in addition to the four ZW historical holes received from Vale.

The Phase 2 drilling program is currently in progress.

Results have been reported for 119 Bravo drill holes to date. Excluding the metallurgical holes, results for 48 Bravo drill holes are currently outstanding.

Schedule 1: Trench Location Details

Schedule 2: Assay Methodologies and QAQC

Samples follow a chain of custody between collection, processing, and delivery to the SGS laboratory in Parauapebas, state of Pará, Brazil. Samples are delivered to the core shack at Bravo's Luanga site facilities and processed by geologists who insert certified reference materials, blanks, and duplicates into the sampling sequence. Samples are placed in secured polyurethane bags, then in security-sealed sacks before being delivered directly from the Luanga site facilities to the Parauapebas SGS laboratory by Bravo staff. Additional information about the methodology can be found on the SGS Geosol website (SGS) in their analytical guides.

Quality Assurance and Quality Control ("QAQC") is maintained internally at the lab through rigorous use of internal certified reference materials, blanks, and duplicates. An additional QAQC program is administered by Bravo using certified reference materials, duplicate samples and blank samples that are blindly inserted into the sample batch. If a QAQC sample returns an unacceptable value an investigation into the results is triggered and when deemed necessary, the samples that were tested in the batch with the failed QAQC sample are re-tested.
