Drilling at Luanga's Central Sector Continues to Impress at Bravo's Luanga Project

VANCOUVER, BC, Feb. 28, 2023 /CNW/ - Bravo Mining Corp. (TSXV: BRVO) (OTCQX: BRVMF), ("Bravo" or the "Company") announced that it has received assay results from seventeen diamond drill holes ("DDH") from the Central Sector at 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. The assay results include fifteen infill diamond drill holes, the last diamond twin holes, and rhodium overlimit assay results.

"New drill results from the Central Sector of our Luanga Project continue to show increased mineralized thicknesses at depth (where it remains open) with similar or better assay grades than historic intercepts. Drilling also continues to demonstrate increasing levels of magmatic nickel sulphides (± copper) both at depth and/or near the basal ultramafics," said Luis Azevedo, Chairman and CEO of Bravo. "Bravo's twin hole drill program, now concluded, has provided confidence in grades and mineralized widths, successfully repeating historic results for some of the thickest, highest-grade intersections. The latest results also include the highest sequential rhodium grades seen at Luanga (DDH22LU043 includes 8.5m @ 6.48g/t rhodium). The exploration potential underlying the ~8.1km mineralized strike at Luanga is just beginning to be revealed."

Highlights Include:

• Assay results received from drilling in the Central Sector continue to show increasing mineralized grades and thicknesses at depth, while also showing increasing magmatic nickel (± copper) sulphide content, both at depth and/or near the basal ultramafic rocks.
• Twin hole DDH22LU043, with nine consecutive rhodium samples grading >1.0g/t Rh, compares well with historic results, intercepting the highest grade mineralized interval known to exist at Luanga and including an exceptional rhodium intercept of 8.5m at 6.48g/t Rh.
• Twin hole DDH22LU083 repeated what it is likely the thickest high-grade mineralized intersection encountered to date at Luanga, with 93.0m at 3.17g/t PGM+Au, comparing very favorably to the historic hole in thickness but with higher PGMs.

Luanga Central Sector Infill Drilling

Drill results received from Luanga's Central Sector continue to show increasing mineralized thicknesses and/or grades at depth and that mineralization is open at depth (see Sections 1, 2 and 3).

Drilling also displays an increasing presence of magmatic nickel (± copper) sulphides, in some cases at depth, where nickel sulphides were not encountered in shallower drilling, and/or in other cases in drill holes that are near the basal ultramafics. Figure 1 shows core photos from three different drill holes reported here, all of which show increasing magmatic sulphides.

Figure 2 shows a larger (~2km of strike) perspective of Luanga's Central Sector, where results from Bravo's infill drilling program can be viewed on this broader scale. The figure shows the greater mineralized widths that are being consistently encountered at depth. It also shows a potentially interesting relationship to increasing nickel grades, which appear to be vectoring towards a significant nickel-in-soil anomaly that is not coincident with the strike direction of the Luanga PGM+Au+Ni deposit (as it is currently understood).

Surface EM (electromagnetics) combined with detailed ground magnetic and micro-gravity surveys are due to commence shortly at the Central Sector. This will extend coverage to the southeast to investigate the basal (footwall) harzburgite (ultramafic) sequence where most of the higher-grade magmatic nickel (± copper) sulphides have been intersected to date and which lies below the main PGM mineralized horizon (as previously defined).

Figure 3 (Section 1 on Figure 7) is an excellent example of drilling by Bravo (shown in blue) returning increased mineralized thicknesses and higher nickel sulphide grades at depth. This relationship progresses from 13m (downhole thickness) in PPT-LUAN-FD0154, to 16m (downhole thickness) in DDH22LU084, to 32m (downhole thickness) in DDH22LU076.

Figure 4 (Section 2 Figure 7) again shows the same thickness progression, from near surface in PPT-LUAN-FD0156 to DDH22LU107 where magmatic nickel sulphides are more prevalent within and/or in close proximity to the basal ultramafic rocks.

Figure 5 (Section 3 on Figure 7) again demonstrates increased mineralized widths with higher magmatic nickel sulphide assay grades at depth and, in this case, with higher PGM+Au assay grades as well. Like the previous section (Figure 4), mineralization is both within and/or in close proximity to the basal ultramafic rocks.

Luanga Twin Hole Drilling Program

During 2022 Bravo completed eight diamond twin holes against selected historic diamond drill holes, for 1,135m.

Results for DDH22LU043 (Figure 6) were finalized after receiving rhodium overlimit assay results for 9 consecutive samples grading >1.00g/t rhodium. Assay results for the Bravo twin drill hole as compared to historic drill hole PPT-LUAN-FD0136 are shown in the table and cross section (Figure 6) below.

The results for the twin holes compare favorably, even given the extremely high-grade nature of the historic drill hole, which was the highest grade wide mineralized interval known to exist at Luanga. Results from both drill holes show a difference of approximately 7%, well within the accuracy and precision ranges for the assay method. Of additional interest is the >20% positive difference in average rhodium grade in favor of the Bravo drill hole, following the receipt of the overlimit results. The deeper mineralized interval in holes DDH22LU043 and PPT-LUAN-FD0136 are also similar in thickness, but with the Bravo twin hole returning an average combined PGM+Au assay grade ~70% higher over a slightly narrower interval.

The final diamond twin hole of the program, DDH22LU083 (Figure 7, North Sector) also returned comparable results to its historic twin, PPT-LUAN-FD0095 as shown below. The assay results show a positive difference of approximately 18% in PGM+AU grade in favor of the Bravo diamond twin hole over identical thicknesses.

Luanga Drill Program Progress

A total of 152 drill holes (17 in 2023) have been completed by Bravo to date, for 25,351 metres (99% of the planned 25,500 metre Phase 1 Drilling Program), including all 8 planned twin holes and all 8 metallurgical holes (not being subject to routine assaying). Results have been reported for 77 Bravo drill holes to date.

Excluding the metallurgical holes, results for 67 Bravo drill holes are currently outstanding.

The Phase 1 diamond drill program is almost completed. Approximately 16 priority drill holes remain to be completed (triggering the Phase 2 program) prior to the commencement of work on Luanga's maiden NI 43-101 Mineral Resource Estimate, which remains on track for H2/2023. The Phase 2 program will be focused on step out drilling (with the objective of extending known zones of PGM+Au+Ni mineralization to depth), follow-up on the newly identified higher-grade nickel ± copper magmatic sulphide mineralization styles, as well as exploration of new targets.

Schedule 1: Drill Hole Collar Details

Schedule 2: Assay Methodologies and QAQC

Samples follow a chain of custody between collection, processing, and delivery to the ALS laboratory in Parauapebas, state of Pará, Brazil. The drill core is 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. Drill core is half cut and placed in secured polyurethane bags, then in security-sealed sacks before being delivered directly from the Luanga site facilities to the Parauapebas ALS laboratory by Bravo staff. Additional information about the methodology can be found on the respective ALS or SGS global websites (ALS, SGS) in their analytical guides. Information regarding preparation and analysis of historic drill core is also presented in the table below, where the information is known.

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.
