Highlights include 45.2m at 1.89g/t PGM+Au, 0.20% Ni; 50.0m at 1.79g/t PGM+Au; And 1.0m at 1.51% Ni
VANCOUVER, BC , June 13, 2023 /CNW/ - Bravo Mining Corp. (TSXV: BRVO) (OTCQX: BRVMF), (" Bravo " or the " Company ") announced that it has received assay results from a further ten infill diamond drill holes ("DDH") from 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 .
"Recent drilling in the Southwest Sector (DDH23LU142) has intercepted the first evidence of magmatic nickel sulphide mineralization outside that previously intersected in the North Sector ( August 16 th , 2022 news release ). This indicates the potential for nickel sulphides at depth along the entire 8.1km strike of the Luanga project. Coupled with the continuing evidence of elevated levels of disseminated nickel sulphides throughout the Central Sector, a HeliTEM survey across the entire Luanga land package has begun, designed to find indications of massive sulphides targets," said Luis Azevedo , Chairman and CEO of Bravo. "The Phase 2 drill program is progressing as planned, with drilling completed to date (assays pending) shown in Figure 4 for reference. This shows where drill coverage is heading and where future results will come from as we begin to explore the next 150m interval of mineralization vertically below the top 150m defined by historical work and Bravo's Phase 1 program."
Highlights Include:
- DDH23LU142 intersected the first evidence of magmatic nickel sulphide mineralization in the in the Southwest Sector (Figure 1).
- Drilling in the Central Sector continues to intercept magmatic nickel sulphides at depth, where results from Bravo's drilling outperform historical shallower drill results.
- Assay results continue to compare well with that of historic drilling on nearby drill sections, both in tenor and mineralized thickness.
- Deeper drilling (Phase 2 program) commenced in the Central Sector, systematically stepping back and extending drill coverage at depth on each section.
- HeliTEM (airborne electromagnetics) over the entire area (7.810ha) of the Luanga project has begun.

Luanga Drilling Update
Results from a further 10 diamond drill holes have been received, six from the Southwest Sector and four from the Central Sector . Results continue to compare well with intercepts in historic drilling on nearby drill sections.
In the Southwest Sector (Figure 1), a 10-15cm zone of magmatic nickel sulphide mineralization was intersected, providing the first evidence of massive sulphides in the Southwest Sector . Assay results also show consistency with historical results for PGMs compared with intercepts in historic drilling on neighbouring drill sections.
Elevated nickel values continue to be a feature of the Central Sector, broadly showing an enrichment in disseminated magmatic nickel sulphide throughout the Central Sector (Figure 2) compared to the North and Southwest Sectors. Drilling in the Central Sector continues to show mineralization dominated by one particularly thick continuous zone of mineralization (Figure 3 – Section 1), extending for kilometres of strike in the Central Sector.
The Phase 2 program, focused on extending drill coverage at depth beyond the coverage of historical drilling, is progressing well. Completed drill holes which are pending assay results are highlighted on Figure 4, demonstrating the pattern of step out drilling on each section through this Sector. Section 1 shows the beginnings of the Phase 2 extensional drilling, in this case extending depth coverage on this section to > 250m from surface.
A total of 182 drill holes (47 in 2023) have been completed by Bravo to date, for 34,149 metres, including all 8 planned twin holes and all 8 metallurgical holes (not subject to routine assaying).
Results have been reported for 148 Bravo drill holes to date. Results for 26 Bravo drill holes are currently outstanding (excluding the metallurgical holes). As evidenced by the constantly decreasing number of holes outstanding at the laboratory, optimization of our assay process is having a positive impact on turnaround times as compared to 2022.
Completed drill holes with results pending are highlighted on Figure 4.

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 . 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 SGS laboratory by Bravo staff. Additional information about the methodology can be found on the SGS Geosol website ( 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.
