VANCOUVER, BC, Nov. 28, 2023 /CNW/ - Bravo Mining Corp. (TSXV: BRVO) (OTCQX: BRVMF), ("Bravo" or the "Company") announced that it has received assay results from thirteen diamond drill holes ("DDH") from the Southwest, Central and North Sectors 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 Phase 2 drill program is progressing as planned, with results extending PGM+Au+Ni mineralization from ~150m to ~400m below surface (see Figures 2 and 3) with comparable thicknesses and grades to those intercepted at shallower depths that were tested during our Phase 1 Program," said Luis Azevedo, Chairman and CEO of Bravo. "Further, additional evidence of magmatic nickel sulphide mineralization at both the North and Central sectors supports the potential for the nickel sulphide mineralization continuing to depth at Luanga. We continue to be encouraged with such results, particularly as we commence drill testing of priority HeliTEM (airborne electromagnetics) targets."
Highlights Include:
Geotechnical drill hole DDH23LU202 in the North Sector, located between HeliTEM anomalies T2 and T3 (not yet drill tested) intersected two zones (6.28m at 1.21g/t PGM+Au, 0.80% Ni including 3.28m at 1.45g/t PGM+Au, 1.02% Ni, and 5.20m at 0.99g/t PGM+Au, 0.84% Ni) of magmatic nickel sulphide mineralization.
DDH23LU204 (49m at 3.12g/t PGM+Au, 0.33% Ni, including 12m at 6.10g/t PGM+Au, 0.54% Ni), shows the continuation of high-grade mineralization from DDH23LU175 on the section to the north, while directly along strike to the south is the untested HeliTEM anomaly T17.
Magmatic Ni sulphides were also intersected in the ultramafic basal sequence at the northern end of the Central Sector in drill holes DDH23LU201 (0.77m at 1.91g/t PGM+Au, 1.65% Ni) and DDH23LU205 (0.70m at 0.08g/t PGM+Au, 1.43% Ni). These intercepts provide further indications of the potential for higher grade Ni sulphide zones in the basal units, stratigraphically below the PGM+Au+Ni mineral resource.
Drilling testing of the 17 priority HeliTEM targets has started.

Given the orientation of the hole and the mineralization, the intercepts are estimated to 120% to 130% of true thickness.

* Bravo's nickel grades are sulphide nickel, and do not include non-recoverable silicate nickel, unlike historical total nickel assays.
Luanga Drilling Update
Results from thirteen diamond drill holes have been received, which includes one of the potential pit-wall geotechnical drill holes and drilling from the Phase 2 Program. Phase 2 drilling is targeting potential extensions of PGM+Au+Ni mineralization down to twice the depth below surface that Bravo drilled in Phase 1. Two of the drill holes reported in this news release are located in the North Sector, including the geotechnical drill hole, seven are in the Central Sector, and three are in the Southwest Sector.
Geotechnical drill hole DDH23LU202 (Figure 1) located in the North Sector shows a wide (>100m) zone of magmatic Ni mineralization within which there are two distinct higher-grade Ni zones (6.28m at 1.21g/t PGM+Au, 0.80% Ni including 3.28m at 1.45g/t PGM+Au, 1.02% Ni, and 5.20m at 0.99g/t PGM+Au, 0.84% Ni), providing further evidence of magmatic nickel sulphides distributed over a significant stratigraphic thickness in the North Sector.
Also potentially significant, DDH23LU202 (Figure 4 – Section 3) intersected magmatic nickel sulphides in the gap between HeliTEM anomalies T2 and T3 (yet to be drill tested) and on strike of both EM anomalies.
Section 1 (Figure 2) in the Central Sector shows DDH23LU204 (49m at 3.12g/t PGM+Au, 0.33% Ni , including 12m at 6.10g/t PGM+Au, 0.54% Ni), which lies directly along strike from previously reported drill hole DDH23LU175 in Figure 3 (54m at 2.33g/t PGM+Au, 0.22% Ni , including 32m at 4.99g/t PGM+Au, 0.30% Ni).
The results from DDH23LU204 define a continuation of a distinct higher-grade zone of mineralization extending from DDH23LU175 on the section to the north and close to the geographic centre of the Luanga intrusion. Assay results from DDH23LU204 show increased PGM+Au and significantly higher Ni sulphide grades as compared to DDH23LU175 to the north. Directly to the south of DDH23LU204 is HeliTEM anomaly T17, which is scheduled to be drilled in the coming months.
Section 2 (Figure 3) shows DDH23LU215 (30m at 1.73g/t PGM+Au, 0.25% Ni), drilled below (down dip) of drill hole DDH23LU175, which demonstrates that mineralization continues at depth, albeit with a lesser thickness in comparison to DDH23LU175. This result, coupled with the significant increase in grade in DDH23LU204 to the south (see Figure 5 for location), could be indicative of a plunging high-grade zone.
At the northern end of the Central Sector, magmatic Ni sulphides were also intersected in the ultramafic footwall in drill holes DDH23LU201 (0.77m at 1.91g/t PGM+Au, 1.65% Ni) and DDH23LU205 (0.70m at 0.08g/t PGM+Au, 1.43% Ni) supporting the potential for zones of magmatic Ni sulphides in the stratigraphic basal units of the Central Sector.
Drill Results Status Update
A total of 238 drill holes (103 in 2023) have been completed by Bravo to date, for 51,217.75 metres, including 8 metallurgical holes (not subject to routine assaying).
Results have been reported for 213 Bravo drill holes to date. Assay Results for 17 Bravo drill holes that have been completed are currently outstanding (excluding the metallurgical holes).
Section 3 below (Figure 4) in the North Zone shows a wide (>100m) zone of magmatic Ni mineralization in DDH23LU202, with two distinct higher-grade Ni zones at its base (6.28m at 1.21g/t PGM+Au, 0.80% Ni including 3.28m at 1.45g/t PGM+Au, 1.02% Ni, and 5.20m at 0.99g/t PGM+Au, 0.84% Ni). DDH23LU202 is in the gap between HeliTEM anomalies T2 and T3, which have yet to be drill tested.

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.
