VANCOUVER, BC, March 21, 2023 /CNW/ - Bravo Mining Corp. (TSXV: BRVO) (OTCQX: BRVMF), ("Bravo" or the "Company") announced that it has received assay results from twenty-seven diamond drill holes ("DDH") concentrated mostly in the Northern 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.

"The latest results from Luanga's Northern Sector continue to provide excellent results, comparing well with historic drilling on nearby drill sections, in both tenor and mineralized thickness. Results also confirm that rhodium is a significant part of the Luanga project, with unique high-grade levels of rhodium now identified in all three Sectors at Luanga." Drilling in the Northern Sector has not yet made significant progress into the basal ultramafic footwall; however, we still see evidence for increasing levels of magmatic nickel sulphides as drilling approaches the basal position," said Luis Azevedo, Chairman and CEO of Bravo. "We look forward to starting the Phase 2 program including testing the potential depth extents of Luanga PGM+Au+Ni mineralization combined with testing the potential for magmatic nickel sulphide mineralization at depth."
Highlights Include:
Assay results received from drilling in the Northern Sector compare well with intercepts in historic drilling on nearby drill sections both in tenor and mineralized thickness.
Mineralization in the Northern Sector of Luanga is typified by multiple stacked zones of PGM+Au mineralization, with magmatic nickel sulphide mineralization appearing to be more prevalent on the footwall (basal) ultramafic side of the system.
Surface geophysical programs have commenced with detailed ground magnetics. Fixed Loop ground electromagnetics (EM) will commence on arrival of the EM crew, while micro-gravity surveying will be completed after the detailed magnetic survey. All geophysical surveys will start in Luanga's Central Sector, where the basal (footwall) harzburgite (ultramafic) sequence is significantly thicker, and nickel potential expected to be better, supported by recent higher-grade nickel intercepts.

Notes:
All 'From', 'To' depths, and 'Thicknesses' are downhole. 'NA' Not applicable for Oxide material. 'EOH' End Of Hole. Given the orientation of the hole and the mineralization, the intercepts are estimated to be 75% to 95% of true thickness. Type: Ox = Oxide. LS = Low Sulphur. FR = Fresh Rock. Recovery methods and results will differ based on the type of mineralization. * Includes result/s Rh >1.00g/t requiring re-assay with a higher detection limit, results pending. ** Bravo's nickel grades are sulphide nickel, and do not include non-recoverable silicate nickel, unlike historic total nickel assays
Luanga Northern Sector Infill Drilling
Drill results received from Luanga's Northern Sector, like results from the rest of the Luanga trend, continue to compare well with intercepts in historic drilling on nearby drill sections, in both tenor and mineralized thickness (see Sections 1, 2, 3). Together, Figures 1 and 2 show an ~2.5km strike perspective of Luanga's Northern Sector, where results presented in this press release can be viewed on a broader scale, displayed over nickel-in-soil geochemistry The ultramafic footwall is towards the eastern (right-hand) side of the figures.
Figure 3 (Section 1 on Figure 6) is typical of mineralization in the Northern Sector of Luanga, where multiple stacked zones of PGM+Au mineralization are hosted in the orthopyroxenite transitional zone, while the footwall ultramafic and its associated more significant magmatic nickel sulphide mineralization is yet to be encountered below.
Figure 4 (Section 2 on Figure 6) again shows multiple stacked zones on PGM+Au mineralization hosted in the orthopyroxenite transitional zone, while the footwall ultramafic is yet to be encountered below.
Figure 5 (Section 3 on Figure 6) is the most southerly section of the Northern Sector. Here multiple stacked zones of mineralization have started to give way to a lesser number of thicker zones of mineralization (typical of the Central Sector) while, at the same time, mineralization passes through vertical in inclination and becomes steeply dipping to the east, where it continues for the next >5km, through the Central and Southwest Sectors (see sections in a previous news release featuring the Central Sector, February 28th, 2023
Luanga Drill Program Progress
A total of 160 drill holes (25 in 2023) have been completed by Bravo to date, for 27,794 metres, including all 8 planned twin holes and all 8 metallurgical holes (not being subject to routine assaying).
Results have been reported for 85 Bravo drill holes to date. Excluding the metallurgical holes, results for48 Bravo drill holes are currently outstanding.
Approximately 9 priority drill holes (4 currently in progress) remain to complete the redrill of the historic mineral resource area. Once these holes are completed and results received, preparation of Bravo's maiden mineral resource estimate for Luanga will commence, and drilling will shift to Phase 2.
The Phase 2 program of work will focus on step out and exploration. Extensional drilling has the objective of extending known zones of PGM+Au+Ni mineralization at depth, below the approximate 150m vertical depth previously defined by historic drilling.
The Phase 2 program also includes a significant budget allocation for exploration. This work will focus on following up newly identified higher-grade magmatic nickel (± copper) sulphide mineralization types identified within the Luanga footwall (stratigraphically below PGM+Au mineralization), the potential feeder zone(s) to Luanga, and the exploration of new targets outside of the currently defined mineralized trends.

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 ALS global website (ALS) in their analytical guide. 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.
