Bravo Continues to Intersect High-Grade PGM's and Ni Sulphide at Luanga
Highlights include 16.9m @ 2.82g/t PGM + Au, plus 0.23% Ni Sulphide, and
13.6m @ 2.67g/t PGM + Au, plus 0.23% Ni Sulphide
VANCOUVER, BC, Sept. 7, 2022 /CNW/ - Bravo Mining Corp. (TSX.V: BRVO), ("Bravo" or the "Company") today announced that it has received assay results from a further twelve infill diamond drill holes ("DDH"), from its wholly owned Luanga PGM (palladium + platinum + rhodium) + gold + nickel project ("Luanga"), located in the Carajás Mineral Province, state of Pará, Brazil. Samples for a further 34 drill holes (including 18 re-assay holes) are already at the laboratory for analysis with results pending. Both downhole and surface electromagnetic ("EM") programs are also underway to follow up on the previously announced massive sulphide intercept.
"The infill drilling and historic core re-assay programs continue to advance rapidly. As we receive more assay results, we continue to see results comparable to the historic grades and thicknesses, increasing our confidence in the prior work completed at Luanga," said Luis Azevedo, Chairman and CEO of Bravo. "The Company is also following up on the recently discovered nickel and copper massive sulphide mineralization that had not been previously identified at Luanga. Downhole EM assisted with the placement of the two follow-up holes (results pending) and the design for drilling on the next drill section. Surface EM will also start shortly, which we hope will greatly assist in vectoring-in and following these potential feeder zone(s)."
Highlights
- Assay results from infill drilling continue to compare well with the drill holes on their neighbouring historic drill sections in both tenor and mineralized thicknesses.
- Highlights of Bravo's recent intercepts are tabulated below, with details attached:

- Additional results from historic drill hole re-assaying are expected in the following weeks.
- Downhole (DH) Transient Electromagnetic (TEM) survey completed on previously reported (August 16rd, 2022 news release) high-grade Ni/Cu massive sulphide hole DDH22LU047;
- Following DHTEM, two new drill holes on the same section have been completed (results pending);
- Drilling on the next section to the north is expected to start soon; and
- Surface Fixed Loop TEM (FLTEM) surveying is expected to commence shortly.
- 67 drill holes have been completed, for a total of 11,091 metres (or 43% of Phase 1 Drilling Program), including 5 twin holes and 6 metallurgical holes.
- 9,621 samples submitted for assay to date including 2,943 re-assay samples from historic drill core.
- 6 drill rigs operating onsite.
Luanga Drill Program
The Phase 1 diamond drill program continues as planned at Luanga. With six drill rigs on site, drilling is now progressing in various locations along the entire 7km strike length of the known Luanga mineralized envelope (defined by historic drilling), including to the north where high-grade massive sulphide nickel/copper mineralization was intersected (see August 16rd, 2022 news release). DHTEM has been completed on this hole (see picture below), and two more drill holes have been completed on the same drill section (results pending), with two more holes about to commence on the section to the north. Surface FLTEM surveying is expected to start soon, to the south of the massive sulphide intercept. To date, 67 DDH have been completed for a total of 11,091m from the planned 25,500m Phase 1 drill program.
Phase 1 drilling is primarily designed to confirm, infill, and step out from the previously defined PGM+Au+Ni mineralization in order to increase confidence in the geological model and provide the basis for future mineral resource estimates. Additionally, drilling will target potential extensions to the mineralization at depth and, given the more recent discovery of massive sulphides, evaluate the potential of this new style of mineralization.

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.
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.
