Bravo's Nickel-Copper Massive Sulphide Intercept Returns High-Grade PGMs
Results Include 11m @ 4.24 g/t 3PGM+Au, 2.04% Nickel + 1.23% Copper
VANCOUVER, BC, Oct. 17, 2022 /CNW/ - Bravo Mining Corp. (TSXV: BRVO) (OTCQX: BRVMF), ("Bravo" or the "Company") today announced that high-grade PGM assay results have been received for previously released diamond drill hole DDH22LU047. Hole DDH22LU047 intercepted high-grade nickel and copper at its Luanga palladium + platinum + rhodium + gold + nickel (PGM+Au+Ni) project ("Luanga"), located in the Carajás Mineral Province, state of Pará, Brazil.
The high-grade intercept in hole - DDH22LU047 graded 4.24 g/t 3PGM+Au with 2.04% nickel and 1.23% copper over 11.04m and occurs in massive and semi-massive sulphides.
"As announced in Bravo's August 16th, 2022 news release, high-grade nickel-copper mineralization had not been previously observed at Luanga. This discovery suggests potential for other metals and styles of mineralization than previously intercepted at Luanga, and we are extremely encouraged that it also contains high grade PGMs," said Luis Azevedo, Chairman and CEO of Bravo. "Downhole EM has commenced and should greatly assist in targeting follow up drilling, whilst surface EM has the potential to identify other massive and semi-massive sulphide mineralization along Luanga's 8.1 km mineralized strike."
Highlights:
HOLE-ID | From (m) | To (m) | Thickness | Pd (g/t) | Pt (g/t) | Rh (g/t) | Au | PGM + | Cu (%) | Ni (%) (Sulphide) | Type |
DDH22LU047 | 131.11 | 142.15 | 11.04 | 3.56 | 0.57 | 0.07 | 0.04 | 4.24 | 1.23 | 2.04 | FR |
Notes: All 'From', 'To' depths, and 'Thicknesses' are downhole. |
Given the orientation of the hole and the mineralization, the intercept is estimated to be 85% of true thickness. |
Type: FR = Fresh Rock. Recovery methods and results will differ based on the type of mineralization. |
- Two diamond drill holes have been completed on each of two drill sections located 50m north and south of DDH22LU047.
- All four step-out drill holes have intersected varying amounts of semi-massive sulphides. Assay results are pending.
- Drill rigs have been temporarily moved clear of the area while borehole electromagnetic surveys ("EM") are completed on these four step-out drill holes.
- Following the completion of borehole EM, surface fixed loop EM will commence over the entire Luanga deposit.

Luanga Drill Program
The Phase 1 diamond drill program continues as planned at Luanga. Six drill rigs are on site, with drilling progressing in various locations along the entire 8.1 km strike length of the known Luanga mineralized envelope (as defined by historic drilling). To date, 91 drill holes have been completed, for a total of 15,554 metres of the planned 25,500 metre Phase 1 drill program.

Location of Bravo Drilling Reported in this Document
Bravo is a Canada and Brazil-based mineral exploration and development company focused on advancing its Luanga PGM + Au + Ni Project in the world-class Carajás Mineral Province of Brazil.
The Luanga Project benefits from being in a location close to operating mines, with excellent access and proximity to existing infrastructure, including road, rail and clean and renewable hydro grid power. The project area was previously de-forested for agricultural grazing land. Bravo's current Environmental, Social and Governance activities includes replanting trees in the project area, hiring and contracting locally, and ensuring protection of the environment during its exploration activities.

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 (ALS) in the analytical guides. IN this case a split is collected by Bravo staff and securely delivered to the Intertek laboratory in Parauapebas where it was assayed by high priority for ore grade Ni and Cu.
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.
