Highlights include 11.0m @ 6.50g/t PGM + Au (including 0.34g/t Rhodium), and 0.32% Ni Sulphide, and 8.6m @ 6.45g/t PGM + Au (including 0.36g/t Rhodium)
VANCOUVER, BC, July 26, 2022 /CNW/ – Bravo Mining Corp. (TSXV: BRVO), (“Bravo” or the “Company“) today announced it has received assay results from a further five diamond drill holes (“DDH”) (four infill drill holes and one twin drill hole), bringing the total to 42 drill holes (including four twin drill holes) completed to date at its wholly owned Luanga platinum group metals (palladium + platinum + rhodium) + gold + nickel (PGM+Au+Ni) project (“Luanga“), located in the Carajás Mineral Province, state of Pará, Brazil. Samples for a further 15 drill holes are already at the laboratory for analysis.
“We are very pleased with the successful launch of Bravo Mining on the TSXV, especially given current market conditions, and believe this underscores the quality of the Luanga Project and its management team. Results from our Luanga Phase 1 (25,500m) confirmation, infill, step out and twin hole drill program continue to both support the historical results and build our ongoing confidence in the Luanga deposit”, said Luis Azevedo, Chairman and CEO of Bravo. “We look forward to providing regular updates as our drilling and re-assay programs continue to ramp up, and our metallurgical and environmental baseline programs get underway.”
- 42 DDH drilled to date, including 4 twin holes, for a total of 6,678m out of Phase 1 25,500m drilling program;
- 5,833 samples submitted for assay and results pending for 15 DDH;
- 5 drill rigs onsite; to be increased to 6 in August 2022;
- Assay results of the twin hole (the third of seven planned twin holes) closely correlate with the immediately adjacent VALE SA historic (“historic” or “historical”) drill hole in both tenor and mineralized thickness, while assays from the four planned drill holes aimed at infilling the existing wide spaced drilling, confirm the tenor, widths and continuity of mineralization seen in adjacent historic drill sections;
- Highlights of Bravo’s intercepts are tabulated below, with details attached.

Luanga Drill Program
The Phase 1 drill program at Luanga is designed to confirm, infill and step out from the previously defined mineralization in order to increase confidence in the geological model and provide the basis for future mineral resource estimates.
As part of the Phase 1 program, Bravo has received final assay results (including palladium, platinum, rhodium, gold and nickel sulphide) for the third twin hole and the first four infill drill holes (shown below and listed in Schedule 1). Samples were submitted to ALS Brasil Limitada’s (“ALS“) preparatory laboratory in Parauapebas, located approximately 72km from Luanga, and then sent to their laboratories in Peru and Vancouver for assaying (Schedule 2).
Drilling by Bravo on new infill sections has, in several parts of the Luanga deposit, intersected zones containing significant amounts of coarser disseminated sulphides not previously observed in historic drilling. An example is shown in the photo below of samples from drill hole DDH22LU039 (assays pending). In some cases, these zones also include narrow bands of semi-massive sulphides. Pending assay results will determine how these zones correlate to grades.
A comparison of the original historic intercept with the Bravo twin hole intercept is tabulated below. Bravo’s twin hole intercept closely correlates with the adjacent historic drill hole in both thicknesses and grade, noting that Bravo nickel grades are for sulphide nickel which is representative of actual potentially recoverable (by froth flotation treatment) nickel, and does not include non-recoverable silicate nickel whereas VALE’s assays were total nickel, including both sulphide and non-recoverable silicate nickel.

Bravo now has five diamond drill rigs operating at Luanga, with the sixth rig off site for servicing. The Phase 1 drill program is focused on confirming the results of the extensive historic drilling that included 252 core holes aggregating 50,353m completed by the previous owner in the early 2000s. The footprint of the Luanga deposit encompasses 238 of these holes. Bravo has now completed 42 holes (aggregating 6,678m of drilling) including four twin holes. Holes are being systematically logged, sampled and sent for assay. To date, 5,833 samples have been submitted for assay. Assay results are currently pending for 15 drill holes.
Drill holes DDH22LU003, 004, 007 and 008 all successfully intersected the main Luanga mineralized zone, which lies at the contact between the mafic and ultramafic rock sequences, confirming the tenor, width and continuation of mineralization seen in nearby wide spaced historic drill sections. DDH22LU008 was collared on top of the main mineralized zone, intersecting grade from surface, while DDH22LU002 was drilled too far north, intersecting the mafic sequence in the hangingwall, which still contains low grade zones of mineralization.

Schedule 2: Assay Methodologies and QAQC
Samples followed chain of custody between collection, processing and delivery to the ALS laboratory in Parauapebas, state of Pará, Brazil. The drill core was delivered to the core shack at Bravo’s Luanga site facilities and processed by geologists who inserted certified reference materials, blanks and duplicates into the sampling sequence. Drill core was 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 (ALS) in the 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.
