Bravo Continues to Intersect Increasingly Wide and High-Grade PGM+Au+Ni Mineralization in the North and Central Sectors at Luanga

 

 

 

 

 

Highlights include 59.9m at 4.80g/t PGM+Au including 42.9m at 5.50g/t PGM+Au, 0.21% Ni,
and 140.7m at 1.25g/t PGM+Au and 45.7m at 1.71g/t PGM+Au, 0.22% Ni

 

Bravo Mining Corp. (TSX-V: BRVO) (OTCQX: BRVMF) has received assay results from nine diamond drill holes, four from the North Sector and five from the Central Sector at its 100% owned Luanga palladium + platinum + rhodium + gold + nickel project, located in the Carajás Mineral Province, state of Pará, Brazil.

 

“Drilling results at Luanga continue to demonstrate upside, notably with DDH24LU240 returning the highest grade/thickness to date. Additionally, DDH24LU038 stands out as the thickest mineralized drill intersection, extending over 140m from surface,” said Luis Azevedo, Chairman and CEO. “Drilling continues to show increasing nickel sulphide grades at depth in the Central Sector, while the North Sector shows widening of multiple zones of mineralization, which has the potential to significantly  improve  ratios of near surface mineralized to unmineralized material.  These positive factors strengthen confidence for on-going drilling.”

 

Highlights Include:

  • Drilling in the North Sector continues to show improvements in both mineralized grade and thickness compared to previously reported drilling in this sector. Grades in and around the transitional weathering zone are higher, influenced by supergene enrichment, as shown on Section 1:
    • 59.9m at 4.80g/t PGM+Au, including 42.9m at 5.50g/t PGM+Au, 0.21% Ni
    • 140.7m at 1.25g/t PGM+Au
  • Mineralization intersected on all three drill sections are at shallow depths (<150m), which augurs well for the future. Furthermore, the substantial volumes of mineralization, indicated by these wide intersections near surface, could support lower strip ratios in these areas.
  • Mineralization remains open at depth, while evidence of increasing PGM and nickel grades at depth remains a common theme in the Central Sector.

Luanga Drilling Update

 

Results from nine diamond drill holes have been received from the North and Central Sectors. All the drill holes herein reported are angled holes (-60 degrees), towards a 090° azimuth in the North and 330° azimuth in the Central Sector. Together, this set of drill holes comprise a total of 1,581 metres of diamond drilling.

 

Section 1 (Figure 1) in the North Sector shows a new infill drill section with DDH24LU238 being the deepest drill hole on the section, exhibiting an exceptionally wide (140m) mineralized intersection. Nearer to surface, this wide zone of mineralization is replicated by two zones of mineralization in DDH24LU240, totalling ~80m of mineralization with the remainder daylighting above surface. The grades in DDH24LU240 are significantly higher, mostly due to the influence of high-grade supergene enrichment in and around the transitional zone above the base of oxidation. There are a further two zones of mineralization stratigraphically below, and all three zones are almost entirely within 150m of the surface, which augurs well for potential future MRE updates at these shallow depths.

 

Section 2 (Figure 2) in the North Sector shows evidence of increasing thickness (~50m) and increased presence of nickel sulphides (0.23% Ni) at depth in DDH24LU241, with mineralization still open at depth. Section 2 is also an infill section and, again, all the mineralization intersected is within <150m below surface. Coupled with the high volume of mineralization near or at surface, both Section 1 (above) and Section 2 (below) demonstrate the potential for improving strip ratios (mineralized to unmineralized material) in these areas, which bodes well for the future.

 

Section 3 (Figure 3) in the Central Sector also shows evidence of increasing grade in both PGM and nickel sulphide mineralization and remains open at depth. The grade of PGM and nickel mineralization intersected in DDH24LU230 (35.2m at 1.59g/t PGM+Au, 0.14% Ni) improves significantly at depth in DDH24LU237 (25.2m at 2.29g/t PGM+Au, 0.24% Ni), while all mineralization on the section is again less than 150m below surface and remains open at depth.

 

Drill Results Status Update

 

A total of 285 drill holes have been completed by Bravo to date, for 61,190 metres, including 8 metallurgical holes (not subject to routine assaying). Results have been reported for 244 Bravo drill holes to date. Assay results for 33 Bravo drill holes that have been completed are currently outstanding (excluding the metallurgical holes).

Schedule 2: Assay Methodologies and QAQC

 

Samples follow a chain of custody between collection, processing, and delivery to the SGS Geosol 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 Geosol 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 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.
