Bravo Confirms Exceptional Rhodium Results from Overlimit Assays at Luanga
![Bravo Confirms Exceptional Rhodium Results from Overlimit Assays at Luanga](https://www.minenportal.de/media/goldseiten-news.jpg)
Highlights include: 6m @ 8.9 g/t PGM + Au (with 1.81 g/t Rh),
Including 2m @ 24.4 g/t PGM + Au (with 5.07 g/t Rh)
VANCOUVER, Oct. 12, 2022 - Bravo Mining Corp. (TSXV: BRVO), (OTCQX: BRVMF), ("Bravo" or the "Company") today announced that it has received the overlimit (>1.0 g/t) rhodium ("Rh") assay results from drill hole PPT-LUAN-FD0065 at its wholly owned Luanga palladium + platinum + rhodium + gold + nickel project ("Luanga" or "Luanga PGM+Au+Ni"), located in the Carajás Mineral Province, state of Pará, Brazil. Preliminary results for PPT-LUAN-FD0065 were announced in the news release dated September 27th, 2022, reporting re-assay of samples from historic diamond drill holes ("DDH"). These results included a 2m interval that exceeded the upper limit of 1.0g/t rhodium for the assay methodology used. This sample was re-assayed for rhodium using the applicable methodology for higher rhodium grades and has returned exceptional rhodium values.
"We are highly encouraged that PGM intercepts are proving to not only correlate well with historic results in thickness but can show significant improvements in grade on re-assay," said Luis Azevedo, Chairman and CEO of Bravo. "We are particularly excited by the high rhodium assay results and believe that the Luanga deposit could be a rare example globally due to its concentration of valuable rhodium metal, particularly in some parts of the deposit."
Highlights
- Mineralized intercepts from the re-assay of historic drill core continue to correlate with the historic intercepts, including intervals where rhodium assay results were >1.0 g/t Rh.
- Highlights from drill hole PPT-LUAN-FD0065, which now include overlimit rhodium re-assays, are tabulated below, with details and comparisons attached:

- 84 drill holes have been completed for a total of 14,579 metres (or 57% of Phase 1 Drilling Program). Currently, samples from 34 drill holes are at the laboratory pending results.
- 13,910 samples submitted for assay to date including 2,964 re-assay samples from historic drill core.
- 6 drill rigs continue to operate onsite.
Luanga Re-Assay and Phase 1 Drilling Progress
A comparison of the historic intercept with the Bravo re-assay result for PPT-LUAN-FD0065 is tabulated below, with a plan showing the location of the drill hole. The thickness for the overall intercept and the higher-grade section within it correlate well with the historic intercepts, with the exception of Rh which significantly exceeds the historic values.

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 7km strike length of the known Luanga mineralized envelope (as defined by historic drilling). To date, 84 drill holes have been completed, for a total of 14,579 metres of the planned 25,500 metre Phase 1 drill program.
Location of Historic Drill Hole Results Discussed in this Report
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 include replanting trees in the project area, hiring and contracting locally, engagement with local communities, and ensuring protection of the environment during its exploration activities.

Schedule 2: Assay Methodologies and QAQC
Samples followed chain of custody between collection, processing and delivery to the ALS laboratory in Parauapebas, state of Para?, 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 quarter 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 respective ALS or SGS global websites (ALS, 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 ("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.
