Bravo Discovers New Nickel-rich Zone in Luanga’s Central Sector and Extends Footprint of
Nickel/Copper-rich Zone in Luanga’s North Sector
Highlights include 27.7m @ 0.62g/t PGM+Au, 0.62% Ni (Including 4.6m @ 1.12g/t PGM+Au plus 1.12% Ni),
And: 25.3m @ 1.14g/t PGM+Au, 0.42% Ni, 0.34% Cu (Including 3.4m @ 2.12g/t PGM+Au, 0.84% Ni, 0.34% Cu)
VANCOUVER, February 14, 2023 – Bravo Mining Corp. (TSX.V: BRVO, OTCQX: BRVMF), (“Bravo” or the
“Company”) announced that it has received assay results from eight diamond drill holes (“DDH”) in the Central
and North Sectors highlighting the nickel sulphide potential of 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. Two DDH in the Central Sector have identified a new zone and style
of nickel sulphide mineralization. Follow up drilling to the previously announced massive sulphide intercept in
the North Sector (August 16 th, 2022 news release ) has intersected higher-grade nickel sulphide 50m to the
north and south, with evidence indicating potential extensions toward the south.
“Today’s results demonstrate the potential for higher-grade nickel ± copper sulphides at Luanga, underlie the
existing ~8.1km strike of PGM+Au+Ni mineralization intersected in shallow historic drilling,” said Luis Azevedo,
Chairman and CEO of Bravo. “We are at the early stages of understanding the distribution of, and controls on, this
potential new style of nickel ± copper sulphide mineralization, which has now been intersected in both the North
and Central Sectors ,” he said. “We are very positive about the potential below Luanga and have deployed
geophysical tools aimed at detecting this style of mineralization. Work is continuing and aims to drill test future
geophysical targets in 2023.”
Highlights Include:
▪ Follow up, step -out drilling to the massive nickel/copper sulphides intercepted in DDH 22LU047 (August
16th, 2022 news release ) intersected nickel/copper sulphides along strike , 50m to the north and to the
south. Electromagnetics (EM) has identified conductors trending to the south where surface EM is ongoing.
▪ Drilling in the Central Sector of Luanga has intersected a new zone and style of nickel sulphide
mineralization, potentially magmatic nickel sulphide mineralization. It occurs within a different rock-type
than the PGM+Au+Ni mineralization at Luanga – further increasing the exploration prospectivity of Luanga.
EM surveying is expected to begin shortly.
▪ A noticeable change in PGM chemistry (significantly higher rhodium to palladium ratio) has been identified
in most assay results from both nickel sulphide zones. This also points to a new style of mineralization and
provides another possible vector into higher nickel sulphide zones.

Central Sector Magmatic Nickel Sulphide Exploration Upside
Drilling in the Central Sector (holes DDH22LU039 and DDH22LU061) identified a second zone of more
concentrated magmatic sulphides, a style of mineralization not previously observed at Luanga in historic drilling.
This style of mineralization features net-textures typical of magmatic nickel sulphide mineralization (Figure 1).
Figure 1: Core photos from Central Sector (039) and North Sector (049 and 052) with nickel ± copper sulphide mineralization.
The Central Sector higher-grade magmatic nickel sulphide mineralization appears to be coincident with the main
Luanga PGM mineralization but appears to have increasing concentrations of nickel sulphides to depth, while
historic nickel-in-soil geochemistry (Figure 2) indicates that nickel sulphide mineralization may be gently diverging
away from the strike of the PGM+Au mineralization. This style of mineralization has only been identified in this
area of the Luanga deposit to date and is hosted in the basal sequence of harzburgites (ultramafic rocks) that
underlie the dominant Luanga orthopyroxenite PGM+Au host rock.

Surface EM completed by Bravo in late 2022 is being extended to the southeast to look deeper into the basal
harzburgite sequence (Figure 3) that underlies the main PGM+Au+Ni mineralization, beyond the extent of current
drilling.
The Central Zone assay results (reported in this news release) from drill holes DDH22LU039 and DDH22LU061
demonstrate a noticeable change in PGM chemistry, where the Pd:Rh ratios range from 4:1 to <2:1. This is a
significant divergence from the majority of existing drill holes across the 8.1km of the main Luanga PGM+Au
mineralized zone, where the Pd:Rh ratio is typically ~10:1. There could also be a relationship between magmatic
nickel and rhodium (high rhodium values highlighted in the table abo ve). This, combined with the identification
of a different host rock , is further supporting evidence of a new style or phase of mineralization that is more
typically associated with magmatic nickel sulphide deposits. Mineralization remains open at depth (Figure 3) and
along strike.

DDH22LU039 is shown in the section below (Figure 3), where the concentration of magmatic nickel sulphides and
nickel assay grades increase (from west to east ) from DDH 22LU054 where fresh rock mineralization has no
significant nickel to report, to DDH22LU039 where magmatic nickel sulphides and assay grades reach their current
peak.

Follow Up on North Sector Massive Magmatic Nickel ± Copper Sulphide Discovery
Follow up drilling to the north and south of the previously announced massive magmatic nickel ± copper sulphide
mineralization in DDH 22LU047 (August 16 th, 2022 news release ) in the North Sector has continued to inters ect
magmatic nickel sulphide mineralization.
New drill results indicate that the nickel ± copper mineralization is coincident with the main Luanga PGM+Au+Ni
deposit, but that higher concentrations of nickel and copper are at depth. Alternatively, this mineralization style
may be unrelated to the emplacement of the PGM portion of Luanga and related to a different, as yet unidentified,
phase of mineralization at depth.
Higher-grade sulphide mineralization and EM anomalism is open to the south (Figure 4) but appears to taper off
to the north . Like the Central Sector above, it may also be diverging away from the strike of the PGM +Au

mineralization and occur below historic drilling to the south. This interpretation is supported to the southern limit
of the current EM survey and is coincident with historic nickel-in-soil geochemistry (Figures 4 and 5).
Most assay results demonstrate the same noticeable change in PGM chemistry as the higher-grade magmatic
sulphide mineralization intersected in the Central Zone, with Pd:Rh ratio s ranging from to 5:1 to <2:1. As
highlighted above this may indicate potential for a different phase or style of mineralization at depth.

Luanga Drill Program Progress
A total of 144 drill holes (9 in 2023) have been completed by Bravo to date, for 23,950 metres (94% of the planned
25,500 metre Phase 1 Drilling Program), including all 8 planned twin holes (results for 2 twin holes outstanding)
and all 8 metallurgical holes (not for routine assaying). Results have been reported for 60 Bravo drill holes to date.
Results for 76 Bravo drill holes are currently outstanding.
The Phase 1 diamond drill program is close to completion, with 1,550m remaining before the commencement of
the Phase 2 diamond drill program. The Phase 2 program will be focused on step out drilling (with the objective
of extending known zones of PGM+Au+Ni mineralization to depth), follow-up on the newly identified higher-grade
nickel ± copper magmatic sulphide mineralization styles, as well as exploration of new targets.
Aside from systematic step-out drilling, the Phase 2 program is designed to support a more intensive approach to
exploration, with work to focus on exploring for magmatic nickel ± copper sulphides. This program will commence
with an extensive program of geophysics consisting of ground EM, ground micro -gravity and ground magnetics.
Targets generated would be drill tested during the Phase 2 program. Phase 2 will also include ongoing
metallurgical test work designed to confirm and optimize metallurgical results reported by Vale SA., Luanga’s
previous owner.

The key deliverable expected from the Phase 1 program is Luanga’s maiden NI 43-101 Mineral Resource Estimate
(MRE). Approximately 3,600m of priority drilling remains to be completed to facilitate this work , including the
balance of the Phase 1 program and a portion of the Phase 2 program . Completion of the maiden MRE remains
on track for H2/2023.
