VANCOUVER, BC, May 25, 2023 /CNW/ - Bravo Mining Corp. (TSXV: BRVO) (OTCQX: BRVMF), ("Bravo" or the "Company") announced that it has received assay results from a further nineteen infill diamond drill holes ("DDH") from 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.

"Recent assay results from infill drilling at Luanga continue to consistently enhance our understanding of the historical data. In the Southwest Sector, DDH22LU116 intersected the thickest known interval of continuous PGM+Au mineralization (in that sector)," said Luis Azevedo, Chairman and CEO of Bravo. "Further trenching is planned in the Southwest Sector to determine whether there is an increase in grade and thickness at surface, similar to what we observed in trenching the Central Sector. Meanwhile, results from drilling of the Central Sector continue to show mineralization dominated by a single thick zone, with higher-than-expected nickel concentrations as drilling continues to advance at depth. We look forward to further testing the potential for mineralization at depth with the Phase 2 drill program, and in particular the commencement of the HeliTEM survey at the end of this month, designed to cover the whole area of the Luanga Project."
Highlights Include:
DDH22LU116 intersected the thickest known interval of continuous mineralization to date in the Southwest Sector, and where mineralization was previously interpreted to narrow (Figure 5).
Drilling continues to intercept magmatic nickel sulphides at depth, especially in the Central Sector where results from Bravo's drilling outperforms historical shallower drilling results.
Assay results continue to compare well with intercepts in historic drilling on nearby drill sections, both in tenor and mineralized thickness, and to previously reported results from Bravo drilling on the same drill sections.
The Phase 2 drilling program commenced in the Central Sector, systematically targeting extensions to Luanga mineralization at depth.
HeliTEM (airborne electromagnetics ("EM")) over the whole area of the Luanga project is scheduled to begin at the end of May.

Notes:
All 'From', 'To' depths, and 'Thicknesses' are downhole. 'NA' Not applicable for Oxide material. '-' Not Assayed.
Given the orientation of the hole and the mineralization, the intercepts are estimated to 105% to 120% of true thickness.
Type: Ox = Oxide. LS = Low Sulphur. FR = Fresh Rock. Recovery methods and results will differ based on the type of mineralization.
* Bravo's nickel grades are sulphide nickel, and do not include non-recoverable silicate nickel, unlike historic total nickel assays
Luanga Drilling Assay Results Update
A total of 178 drill holes (43 in 2023) have been completed by Bravo to date, for 32,799 metres, including all 8 planned twin holes and all 8 metallurgical holes (not subject to routine assaying).
Results have been reported for 138 Bravo drill holes to date, which includes all drilling completed in 2022. Excluding the metallurgical holes, results for32 Bravo drill holes are currently outstanding.
Drill results received from all three sectors at Luanga continue to compare well with intercepts in historic drilling on nearby drill sections and/or results from Bravo and historical drilling on the same drill sections (Figures 1, 3 and 4).
The Central Sector (Figure 1) continues to show mineralization dominated by one thick zone, with consistent thicknesses on section (Figure 3 – Section 1). Phase 2 drilling, which commenced in the Central Sector in April 2023, is systematically targeting the extension of existing PGM+Au+Ni mineralization to a greater depth.
Elevated nickel values (Figure 2) also continue to be a feature of the Central Sector, compared to historical results and in comparison to the North and Southwest Sectors, on a broad scale. This may be related to a significantly thicker basal (footwall) harzburgite (ultramafic) sequence, which is also coincident with a more prolific nickel-in-soil geochemical footprint.
Drilling in the Southwest Sector also shows consistency with assay results both for PGMs and magmatic nickel sulphides (Figure 4 – Section 2), comparing well with intercepts in historic drilling on neighbouring drill sections and with drilling by Bravo on the same section.
Phase 2 Program
The Phase 2 program commenced in April 2023, with 21,500 meters of drilling planned, focused on extensional drilling to depth (below the known mineralization) and exploration of new targets.
Surface geophysical programs, micro-gravity and detailed ground magnetics remain in progress at Luanga, while HeliTEM (airborne EM) covering the entire Luanga project is scheduled to begin at the end of May.

Forward Looking Statements
This news release contains forward-looking information which is not comprised of historical facts. Forward-looking information is characterized by words such as "begin", "compares well", "confirm", "continues", "determine", "look forward to", "plan", "potential", "schedule", "targeting", variants of these words and other similar words, phrases, or statements that certain events or conditions "may" or "will" occur. This news release contains forward-looking information pertaining to the Company's ongoing drill program and the results thereof including the potential for increases in grade and thickness closer to surface in the Southwest Sector and higher Ni grades at depth, the interpretation of magmatic Ni sulphides, the interpretation of a single main mineralized zone in the Central Sector and the comparisons to historical and prior Bravo drilling; the expected completion of geophysical surveys and the results of such surveys; the potential for the definition of new styles of mineralization (including magmatic Ni sulphides and their potential association with thicker basal harzburgite sequence) and the potential for extensions to mineralization at depth; and the Company's plans in respect thereof. Forward-looking information involves risks, uncertainties and other factors that could cause actual events, results, and opportunities to differ materially from those expressed or implied by such forward-looking information. Factors that could cause actual results to differ materially from such forward-looking information include, but are not limited to, unexpected results from exploration programs, changes in the state of equity and debt markets, fluctuations in commodity prices, delays in obtaining required regulatory or governmental approvals, environmental risks, limitations on insurance coverage; and other risks and uncertainties involved in the mineral exploration and development industry. Forward-looking information in this news release is based on the opinions and assumptions of management considered reasonable as of the date hereof, including, but not limited to, the assumption that the assay results confirm that the interpreted mineralization contains significant values of nickel, PGMs and Au; that the mineralization remains open to depth, that Ni grades are improving to depth, that final drill and assay results will be in line with management's expectations; that activities will not be adversely disrupted or impeded by regulatory, political, community, economic, environmental and/or healthy and safety risks; that the Luanga Project will not be materially affected by potential supply chain disruptions; and general business and economic conditions will not change in a materially adverse manner. Although the Company believes that the assumptions and factors used in preparing the forward-looking information in this news release are reasonable, undue reliance should not be placed on such information.

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.
