Bravo's Exploration Continues to Show Potential at Multiple Targets

Highlights include 6.7m at 2.6% Cu, 0.6g/t Au, 2.9m at 6.0% Cu, 0.4g/t Au at T5 Target; and 6.5m at 2.3% Cu, 0.55% Ni at T16 Target

TORONTO, Sept. 9, 2025 /CNW/ - Bravo Mining Corp. (TSXV: BRVO) (OTCQX: BRVMF), ("Bravo" or the "Company") is pleased to announce recent results at its 100% owned Luanga Project on targets adjacent to, and beyond the limits of, the Luanga palladium + platinum + rhodium + gold + nickel deposit ("Luanga deposit" or "Luanga PGM+Au+Ni deposit"), located in the Carajás Mineral Province, Pará State, Brazil.

"Drilling and geophysical work continue to demonstrate the potential scale and diversity of exploration opportunities across Luanga, with both IOCG and magmatic Ni-Cu mineralization identified at several of the 17 anomalies prioritized for evaluation. The 2025 program has, so far, confirmed extensions to the copper-gold mineralization at T5, returned encouraging results in scout drilling at T16 and T17, and we are now expanding our focus to new targets such as Babylon, which encompasses a large magnetic signature. Our exploration is systematically building a pipeline of exploration prospects that highlight Luanga's potential well beyond the PGM+Au+Ni deposit itself," said Luis Azevedo, Chairman and CEO. "Further, with the recently reprocessed geophysical datasets, we are also investigating the potential for deep extensions to Luanga's PGM+Au+Ni mineralization, while refining drill targeting across the IOCG and magmatic Ni-Cu prospects to test these targets at depth. In parallel, we are continuing to advance metallurgical optimization work and other economic studies on the PGM+Au+Ni deposit throughout the year, which will support the completion of a Pre-Feasibility Study".

Highlights Include

• T5 Prospect: Drilling confirmed up-dip extensions of Cu-Au mineralization, with intercepts including 6.2m @ 2.07% Cu & 0.48 g/t Au (DDH2505T026), 6.65m @ 2.57% Cu & 0.55 g/t Au (DDH2505T024), and 2.91m @ 6.01% Cu & 0.43 g/t Au (DDH2505T025). Results support a structurally controlled IOCG-style system; development of a 3D geological and structural model is underway to guide a follow-up drill program.
• T16 Target: A strong EM conductor located outside the Luanga PGM deposit, where scout drilling confirmed lateral continuity of Cu-Ni mineralization, highlighted by DDH2516T005 which returned 6.54m @ 2.25% Cu & 0.55% Ni within a 7.8m-wide hydrothermal system, with massive to semi-massive sulphides. Additional assay results are pending.
• Babylon Ni-Cu Target: New drilling and BHEM survey underway over this target located stratigraphically below the Luanga PGM deposit and associated with a large magnetic anomaly together with a strong EM conductor and a gravity high. Previous drilling at this target intercepted 11.04m @ 2.04% Ni & 1.23% Cu (DDH22LU047).

T5 Target – Exploration Update

Bravo conducted a short drilling program to evaluate the potential for up-dip extensions to the Cu-Au mineralization at the T5 prospect. Six drill holes, totaling 1,004 linear metres, were drilled in Q2 2025, with four intercepting the main mineralized structure.

The Cu-Au sulphide mineralization at T5 occurs primarily as chalcopyrite with subordinate pyrrhotite plus pyrite and can be grouped into four main styles: (i) massive to semi-massive sulphide, (ii) disseminated, (iii) brecciated, and (iv) vein.

The sulphide mineralization is enveloped by a hydrothermal zone associated with the development of biotite, actinolite, scapolite, chlorite, phlogopite, apatite, tourmaline, carbonate and silica. Work to date indicates that the Cu-Au mineralization at T5 is structurally controlled by a WNW-ESE fault, dipping steeply to NNE, developed during a brittle to brittle-ductile regime (brecciation with incipient foliation) that generated irregular open-spaced traps for mineral deposition. Consequently, the thickness of mineralization varies dramatically over relatively short distances. The precipitation of sulphides and Cu-Au grades are likely controlled by this regime.

The host rock is a tonalitic intrusion (supported by petrographic studies) that has a defined Th + U radiometric signature on the airborne radiometric survey. The hydrothermal assemblage, together with the structural control, suggest the T5 Cu-Au mineralization can be postulated as an Iron Oxide Copper Gold ("IOCG") type occurrence, which is a typical style of mineralization in the Carajás Mineral Province.

Drill hole DDH2505T026 intercepted the main structure, intercepting 6.2m @ 2.07% Cu, 0.48g/t Au from 99.36m downhole, and a splay fault which returned 8.31m @ 1.65% Cu, from 65.55m downhole (Figure 1). This drillhole is the up-dip extension of the mineralization intercepted on previous hole DDH2405T003 (5.19m grading 3.10% Cu and 1.12g/t Au, from 157.91m downhole).

Drill hole DDH2505T024 was drilled up-dip of hole DDH2405T02 (11.5m @ 14.27% Cu, 3.33g/t Au, from 165.62m downhole) and downdip of hole DDH2405T005 (6.0m @ 1.19% Cu, 0.49g/t Au, from 42.50m downhole). DDH2505T024 intercepted a 7.30m wide interval composed of a typical potassic hydrothermal halo, with a sulphide-rich zone within it. Locally, mineralization has a breccia texture, commonly with chalcopyrite being the dominant sulphide mineral (Figure 2). The interval in DDH2506T024 returned 6.65m @ 2.57% Cu and 0.55g/t Au, from 114.25m downhole.

DDH2505T025 was drilled up-dip of DDH2405T015 (13.4m @ 2.93% Cu, 0.39g/t Au, from 121.70m downhole). DDH2505T025 intercepted a breccia zone composed by silica, biotite, amphibole, carbonate, tourmaline and up to 40% sulphides, mostly chalcopyrite and minor pyrite. This interval returned 2.91m @ 6.01% Cu, 0.43g/t Au, from 91.79m downhole.

The Company is currently developing a 3D geological and structural model for T5, and a follow-up drill program will be designed based on this work.

Drilling: T16 HeliTEM Target

T16 is a strong electromagnetic (EM) conductor situated outside the Luanga deposit and was the subject of initial scout drilling in 2024. Two drill holes completed in 2024 intersected breccia sulphide mineralization, revealing promising Cu and Ni grades, associated with low platinum-group metal (PGM) values. The best drill intercepts in 2024 included: 1.29m @ 2.39% Cu, 1.27% Ni, from 94.59m downhole (DDH2416T001) and 3.0m @ 0.87% Cu, 0.48% Ni, from 99.30m downhole (DDH2416T002).

Five drill holes, comprising 761 linear metres have been drilled at T16 during 2025. Results of three drill holes have been received to date.

DDH2516T005 was drilled 25m to the northeast of previous drillhole DDH2416T001 to test the lateral continuity of the Cu-Ni mineralization. The hole intercepted a 7.8m-wide hydrothermal system comprising biotite, actinolite, scapolite and almandine.

Massive to semi-massive sulphide zones occur within this alteration zone, locally showing breccia-textures and suggesting the presence of two generations of sulphides, the first being chalcopyrite-rich and the second pyrrhotite-rich. The hydrothermal system is hosted within basement rocks of dioritic to tonalitic composition, stratigraphically below the Luanga deposit. Results include 6.54m @ 2.25% Cu, 0.55% Ni, from 82.96m downhole (Figures 4 and 5).

DDH2516T004 was drilled 25m to the northeast of previous drillhole DDH2416T002 (3.0m @ 0.87% Cu, 0.48% Ni, from 99.30m downhole) to test the SW lateral continuity of Cu-Ni mineralization. The hole intercepted a wide hydrothermal zone with an apparent thickness more than 20 metres. Sulphides (mostly chalcopyrite) occur along foliation planes within an internal zone of 2.0m @ 0.87% Cu, from 108.75m downhole.

Assays for holes DDH2516T006 and DDH2516T007 are currently pending however, both holes intercepted the same hydrothermal system locally, with internal brecciation associated with sulphide-rich zones (Figures 6 and 7).

DDH2516T003 was drilled to test a localized silicified zone containing malachite (Cu oxide), that outcrops at T16, striking in a NW-SE trend. The hole did not intercept mineralization. A trenching program is planned to better investigate the potential of this style of mineralization.

Drilling: T17 HeliTEM Target

This target is located within the Central Sector of the Luanga deposit, close to a complex structural zone that offsets this sector from the Southwestern Sector. Malachite-bearing gossans occur as float blocks at surface, while geological mapping indicates that the distribution of the gossanous blocks is controlled by this NW-SE regional structure which crosscuts the Luanga PGM deposit.

A shallow drill hole (DDH2517T004 – 120m depth) was drilled to investigate Cu potential along the interpreted structure. The hole intercepted 2.0m @ 0.51% Cu immediately below the base of oxidation, 23.35m downhole. Assay results for the oxide zone are pending.

Babylon Ni-Cu Target

The Babylon target is situated within and stratigraphically below the Luanga deposit and it is associated with a large magnetic anomaly, together with a strong EM conductor and a gravity high (Figure 9). Previous drilling conducted by Bravo in this area, as part of the Luanga PGM program, intercepted high grade magmatic massive sulphide Ni-Cu-PGM mineralization (Hole DDH22LU047 11.04m @ 2.04% Ni, 1.23% Cu, from 131.11m downhole. See news release dated October 17, 2022).

Sulphide mineralization sits at the geologic base of the Luanga deposit in the North Sector and occurs close to the top of a deeper hydrothermal alteration zone related to Fe-Ca-K metasomatism. The main metasomatic alteration assemblage includes magnetite, chlorite, amphibole (actinolite, grunerite and minor hornblende), and garnet (almandine). Sulphide paragenesis is presented by pyrrhotite >> pentlandite (Ni) > chalcopyrite (Cu).

Bravo is currently carrying out a follow-up diamond drilling program, to be followed by a Bore Hole Electromagnetic ("BHEM") survey, with results expected in coming months.

Geophysical Approach for Luanga Deposit, IOCG and Magmatic Ni Targets

Recently, the Company reprocessed the HeliTEM data to produce new products such as the Magnetization Vector Inversion ("MVI") 3D Model and Self-Organizing Maps ("SOM") to further enhance the Company's regional and structural understanding within the Luanga Project area.

The integration of these new products (Figure 10), together with data generated previously (for example; ground magnetic, ground microgravity and Induced Polarization), will assist the Company in its investigations of the potential for deep extensions to the PGM+Au+Ni mineralization within the Luanga deposit, and will also help to increase the confidence of ongoing drill testing over the current portfolio of IOCG and Magmatic Ni (±Cu) targets within the Luanga Project.

Drilling & Trenching Status Update

A total of 367 drill holes has been completed by Bravo to date, for 76,281.90 metres, including 8 metallurgical holes (not subject to routine assaying). Results have been reported for 347 Bravo drill holes to date. Assay results for 12 holes are currently outstanding (excluding the metallurgical holes). A total of 49 trenches has been completed to date (for 9,813.85 metres), with results from 4 exploration trenches pending.
