Bravo Intersects Shallow, Wider and Higher-Grade PGM+Au+Ni Mineralization in the North Sector at Luanga

 

 

 

 

 

Highlights include 29m at 2.40g/t PGM+Au, 0.10% Ni (including 3m at 1.41g/t Rhodium), and 22m at 1.82g/t PGM+Au, 0.14% Ni

 

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

 

“Results continue to extend PGM+Au+Ni mineralization at depth, now in the North Sector, with mineralization extending from ~100m to ~200m below surface, which is still relatively shallow when compared to the greater than 400m depths demonstrated in the Central Sector,” said Luis Azevedo, Chairman and CEO of Bravo. “Again, assay grades and mineralized thicknesses typically  improve at depth, as can be seen in Figures 1 and 2. We also see early evidence of copper sulphides in greater concentration relative to nickel sulphides, as well as localized high-grade rhodium, in the North Sector.”

 

Highlights Include:

  • Drilling in the North Sector continues to improve in grade and thickness below the limits of the current Mineral Resource Estimate for example:
    • DDH23LU224 on Section 1 (28.9m at 2.44g/t PGM+Au, 0.10% Ni) is significantly thicker and higher-grade compared to up dip hole DDH23LU202 (10.0m at 0.80g/t PGM+Au, 0.12% Ni).
    • DDH23LU219 on Section 2 (22.4m at 1.82g/t PGM+Au and 9.1m at 2.22g/t PGM+Au) is also a significant improvement over historic drill hole PPT-LUAN-FD0002 up dip (11.7m at 1.08g/t PGM+Au and 20.0m at 0.77g/t PGM+Au respectively).
  • The North Sector drilling is at an earlier stage as compared to the Central Sector, where mineralization has been extended to depths of more than 400m. The potential to define and extend existing mineralization below depths as shallow as 100m is now being demonstrated.
  • Results in the North Sector continue to support the potential for future growth in Luanga’s MRE.
  • Narrow zones of copper sulphides and localized high-grade rhodium have also been intersected in the North Sector.
  • Bore-hole Electromagnetic survey team working in parallel with exploration drilling.

Luanga Drilling Update

 

Results from seven diamond drill holes have been received from the North Sector. All the drill holes herein reported are angled holes (60 degrees) towards a 090° azimuth. Together, this set of drill holes comprise a total of 2,204 metres of diamond drilling.

 

Section 1 (Figure 1) in the North Sector shows DDH23LU224 which was drilled to test below DDH23LU202. PGM+Ni mineralization intersected in DDH23LU224 (28.9m at 2.44g/t PGM+Au, 0.10% Ni) is significantly thicker and higher-grade compared to the up-dip intersection in DDH23LU202 (10.0m at 0.80g/t PGM+Au, 0.12% Ni), and is less than 150m from surface. This bodes well for future growth in the MRE at relatively shallow depths. The zone of disseminated nickel sulphides in DDH23LU202 was not repeated in DDH23LU224; however, narrow zones of higher-grade nickel sulphide mineralization observed in DDH23LU224 are now associated with increasing levels of copper mineralization at depth.

 

Section 2 (Figure 2), in the North Sector, also shows evidence of increasing widths and grades at relatively shallow depths. DDH23LU219 (22.4m at 1.82g/t PGM+Au and 9.1m at 2.22g/t PGM+Au) is also a significant improvement over the up-dip intercept in historic drill hole PPT-LUAN-FD0002 (11.7m at 1.08g/t PGM+Au and 20.0m at 0.77g/t PGM+Au respectively) and, as with Section 1, these results bode well for future MRE growth at relatively shallow depths.

 

Drill Results Status Update

 

A total of 260 drill holes have been completed by Bravo to date, for 56,147.80 metres, including 8 metallurgical holes (not subject to routine assaying). Results have been reported for 227 Bravo drill holes to date. Assay results for 25 Bravo drill holes that have been completed are currently outstanding (excluding the metallurgical holes).

 

Drilling of priority HeliTEM (airborne electromagnetics) targets is now accompanied by a borehole EM survey team, on site at Luanga, progressing in parallel with drilling.

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.
