VANCOUVER, BC, April 15, 2024 /CNW/ - Bravo Mining Corp. (TSXV: BRVO) (OTCQX: BRVMF), ("Bravo" or the "Company") announced that it has received assay results from seven trenches in the Central Sector at its 100% owned Luanga palladium + platinum + rhodium + gold + nickel project ("Luanga" or "Luanga PGM+Au+Ni Project"), located in the Carajás Mineral Province, state of Pará, Brazil.

"Bravo's trenching program continues to return excellent results that are better than the average oxide grades reported in the existing Mineral Resource Estimate ("MRE"). In addition, the increased lateral extent of oxide PGM+Au mineralization at surface is likely to increase the oxide volume component of a future MRE update. The high-grade zones present within these broad intersections also continue to validate or improve the higher grades seen in the drilling below the trench lines, further supporting our interpretation of supergene enrichment," said Luis Azevedo, Chairman and CEO of Bravo. "Furthermore, it is encouraging to see trenching results from the Central Sector continuing to show the same broad lateral distribution that was consistently observed in the Northern Sector, which bodes well for future resource growth."
Highlights Include:
Results from the trenches reported are from the northern end of the Central Sector and continue to show broad distribution of oxide mineralization (158m wide in TRC23LU013 and 152m wide in TRC23LU015).
These results continue to demonstrate the much greater lateral extents of surface oxide mineralization in comparison to the narrower zones of primary (fresh rock) mineralization in drilling below the trenches.
Results confirm the presence of supergene enrichment in the saprolite zone (above the base of oxidation), encountering grades that are generally higher than MRE average grades for oxide mineralization.
Grades in trenches further corroborate or improve upon intersections encountered by drilling in the underlying fresh rock, while higher-grade zones within trenches, such as TRC23LU015 (17m at 2.30g/t PGM+Au) also validate or surpasses the high-grade intersections encountered by drilling.
Grades are consistently better than MRE average grades for the oxide zone which, in combination with the broader distribution, suggest potential for increased tonnes of oxide mineralization at higher grades in future mineral resource updates.
Trenching is planned to continue along the entire 8.1km strike length of the Luanga deposit, with work now progressing through the Central Sector, towards the Southern Sector.

Luanga Trenching Program
Trenching across the strike of the outcrop/sub-crop aims to better interpret near surface mineralization and to reduce the distance/spacing between assay data points for later resource classification to the indicated category. The program continues to be highly successful.
Trenches TRC24LU009 to 012 and TRC23LU013 to 015 cover the northern end of the Central Sector (Figure 1). Trenching continues in the Central Sector, progressing towards the Southwest Sector. Figure 4 shows the location of trenches reported in this press release.
Trenching results continues to highlight significant expansion in the lateral extent of shallow oxide mineralization, which extends out across the topographic high that is a ridge and down its flanks, along the 8.1km strike length of the Luanga deposit. Results continue to confirm the presence of supergene enrichment in the saprolite zone (above the base of oxidation), encountering grades that are generally higher than MRE average grades for oxide mineralization. Grades are supported by shallow intersections in nearby drillholes, and as reported in previous trench results (see December 14th 2023,September 26th 2023 and May 08th, 2023).
Figure 2 (Section 1) demonstrates the extent of surface oxide mineralization, in comparison to the narrower zones of primary (fresh rock) mineralization in drilling below the trench. This "mushrooming" of oxide mineralization in the supergene zone demonstrates the potential for volumetric growth in future oxide mineral resources that were previously not possible to define by drilling alone.
Trenching to date continues to be successful, and is likely to enhance future MREs, all while being very cost effective. Trenching is planned to continue along the entire 8.1km strike length of the Luanga deposit, with work now progressing in the Central Sector
Figure 3 (Section 2) also shows a significant blanket of oxide mineralization at surface, in comparison to fresh rock mineralized widths in drilling below the trench. While the higher-grade zone within trench TRC23LU015 (17m at 2.30g/t PGM+Au) supports or improves on the highest-grade intersections encountered by drilling below.
The same sampling, assay laboratory procedures and QAQC protocols as applied to drill core sampling are applied to trench samples.
Luanga Drilling & Trenching Status
A total of 280 drill holes have been completed by Bravo to date, for 60,168.40 metres, including eight metallurgical holes (not subject to routine assaying). Results have been reported for 235 Bravo drill holes to date. Assay results for 37 Bravo drill holes that have been completed are currently outstanding (excluding the metallurgical holes).

Schedule 2: Assay Methodologies and QAQC
Samples follow a chain of custody between collection, processing, and delivery to the SGS 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 SGS laboratory by Bravo staff. Additional information about the methodology can be found on the SGS Geosol website (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.
