Bravo Continues to Intersect Exceptional PGM Mineralized Thicknesses and Grades at Luanga

 

 

 

 

 

 

Highlights include 19.8m @ 7.1g/t PGM+Au

 And 50.9m @ 2.64g/t PGM+Au plus 0.30% Ni

And 30.5m @ 3.09g/t PGM+Au plus 0.30% Ni

 

Bravo Mining Corp. (TSX-V: BRVO) (OTCQX: BRVMF) announced that it has received assay results from an additional 13 infill diamond drill holes from its Luanga palladium + platinum + rhodium + gold + nickel project, located in the Carajás Mineral Province, state of Pará, Brazil.

 

“The southern extent of the Central Zone at Luanga continues to show thick, high-grade mineralized intersections (including higher levels of nickel sulphide) in an area that was previously sparsely drilled with only shallow holes on 200m spaced sections. Intersections in previously released drill holes DDH22LU040 (52.9m @ 2.14g/t PGM+Au plus 0.27% Ni from 36.6m) and DDH22LU042 (67.3m @ 1.35g/t PGM+Au plus 0.28% Ni from 47m) are further supported by wide high-grade intersections in DDH22LU053 (50.9m @ 2.64g/t PGM+Au plus 0.30% Ni, from 90.5m), DDH22LU058 (30.5m @ 3.09g/t PGM+Au plus 0.30% Ni, from 115.4m), and DDH22LU059 (17.1m @ 3.97g/t PGM+Au plus 0.22% Ni, from 17.2m), ” said Luis Azevedo, Chairman and CEO of Bravo. “These sections all remain open at depth, representing a substantial upside opportunity. This part of the Central Zone at Luanga is an ideal location for the first deeper drilling, as part of our Phase 2 Drilling Program, given evidence of significantly improving grades and widths at depth, coupled with higher-than-expected nickel sulphide grades.”

** Bravo’s nickel grades are sulphide nickel, and do not include non-recoverable silicate nickel, unlike historic total nickel assays.
  • 138 drill holes (3 holes in 2023) have been completed by Bravo to date, for a total of 23,265 metres (or 91% of the planned 25,500 metre Phase 1 Drilling Program), including all 8 planned twin holes and all 8 planned metallurgical holes.
  • Results reported for 52 Bravo drill holes to date. Results for 78 Bravo drill holes remain outstanding.

 

Luanga Drill Program

 

The Phase 1 diamond drill program is close to completion, with 2,235m remaining before the commencement of the Phase 2 diamond drill program, which will be focused on step out drilling and extending known zones of mineralization at depth.  Phase 2 will also include drill testing geophysical targets from the ongoing ground electromagnetic geophysical program and the planned micro-gravity geophysical program.  Drilling for 2023 started after the end of year break, with four drill rigs currently operating on site given the significant backlog of assays and higher drill production rates later in 2022.

 

Results from Luanga’s Central Zone continue to show wide high-grade mineralized intersections (including high nickel sulphides) in an area that was previously drilled with shallow holes on wide spaced sections. All sections remain open at depth (see plan and sections below), presenting a substantial upside opportunity and an ideal location for planned Phase 2 deeper drill testing.

Results from Bravo’s drilling continue to show the same as trend noted previously, with results comparing well with, or exceed intercepts in historic drill holes on nearby drill sections, in both tenor and mineralized thickness. Hole DDH22LU044 was collared on an exploration target far from the mineralized horizon. Hole DDH22LU035 was drilled too far east, starting in footwall rocks below the mineralized zone, before exiting the Luanga complex and intersecting low grade copper mineralisation associated with hydrothermal alteration.

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 in the analytical guides.

 

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.
