Drilling at T11 Target intersects four
significant sulphide-rich intervals
VANCOUVER, BC, July 8, 2024
/CNW/ - Bravo Mining Corp. (TSX.V: BRVO) (OTCQX:
BRVMF), ("Bravo" or the "Company") has received
assay results from the two drills hole at the "T5" target, and
intersected sulphide mineralization in drilling at the "T11"
electromagnetic ("EM") target at its 100% owned Luanga Project
("Luanga") which includes the Luanga palladium + platinum +
rhodium + gold + nickel deposit, in the Carajás Mineral Province,
Brazil.
"Bore-Hole EM (BHEM) is now progressing on all holes at EM
target T5. This will better define the orientation of
mineralization ahead of drill testing. Whilst it was anticipated
from the lesser amounts of copper mineralization in DDH2405T003
that grade may not be as high as assay results from previous holes,
this intersect extends the higher-grade copper-gold mineralization
over a significant area. Target T5 therefore remains open along
strike and depth which is interpreted to be very
promising" said Luis
Azevedo, Chairman and CEO. "Drilling also continues to
advance other targets within the portfolio of EM anomalies. At T11,
drilling of BHEM anomalies has intersected multiple zones of
sulphide mineralization and while this is also very encouraging, we
are still at early stage of these discoveries with a regular flow
of exciting news expected in near future" he said.
- Hole DDH2405T003 at T5 Target, located 50m west and along strike of previously reported
high-grade hole DDH2405T002, intersected 5.2m of semi-massive/breccia hosted copper
sulphide mineralization grading 3.1% Cu and 1.1g/t Au (Figure
2).
- Copper-gold mineralization at T5 Target remains open at
depth and along strike.
- BHEM surveys at T5 is in progress, including holes
DDH2405T003, 04, 05 and 06 which will position Bravo for the August
drill program.
- At T11, drill hole DDH2411T002 intersected four significant
sulphide-rich intervals within a broader alteration zone.
Pyrrhotite > pentlandite >> chalcopyrite is present as
patches/veins, locally massive to semi-massive textures
(Figure 1. Assays pending). BHEM in progress.

and at depth.
Exploration Drilling Update
Assay results have been received from diamond drill holes
DDH2405T003 and DDH2405T005 at the T5 target, located 1km
east of the Luanga PGM Deposit. Drill hole DDH2405T006 has also
been completed and intersected strong alteration interpreted to be
proximal to the mineralization (assays pending). BHEM was completed
on the pilot hole (DDH2311T001) at HeliTEM target "T11".
BHEM anomalies defined from this drill hole indicated that the
targets were deeper, below the drill hole. These refined
targets were then successfully tested by DDH2411T002, which
intersected sulphide mineralization. Together, this drilling of
HeliTEM and BHEM anomalies comprises a total of 1,179 metres.
Bravo continues to conduct systematic first-pass drilling,
coupled with BHEM, on the priority EM conductors identified by the
HeliTEM survey. Although these modelled HeliTEM conductors have a
lower degree of locational accuracy, they are sufficiently defined
to position first-pass drilling proximal to the conductor's
location. From there, BHEM provides more precise location of EM
anomalies for drill testing. Of the 17 priority EM anomalies
identified in the HeliTEM survey (see press release September 11, 2023), Bravo had narrowed this list
to 11 high priority conductors that warranted follow-up drilling of
predominantly off-hole BHEM conductors. T5, T6, T16 and now T11 are
four of these 11 HeliTEM targets.
T5 Target
Figure 2 shows the mineralization intersected in DDH2405T003 at
the T5 target (Figure 5), located 50m
west and along strike of previously reported high-grade copper-gold
mineralization in hole DDH2405T002 (see press release May 28, 2023) which intercepted 11.48m at 14.3% Cu, 3.3g/t Au including
2.9m at 22.9% Cu, 3.6g/t Au.
Figure 2: Breccia copper sulphides in DH2405T003 (158.9 –
162.5m shown).
Drill hole DDH2405T003 (Figure 3) intersected 5.2m (grading 3.1% Cu, 1.1g/t Au) of
breccia-hosted copper sulphide mineralization, at the T5
target. Like hole DDH2405T002, located 50m to the east, mineralization is interpreted to
be consistent with typical copper/gold mineralization seen in the
Carajás Mineral Province, and unrelated to the Luanga PGM+Au+Ni
Deposit.
DDH2405T006 (Figure 3. Assays pending) has been completed
down-dip of (below) hole DH2405T002, intersecting significant
hydrothermal alteration consistent with that expected proximal
(close) to the mineralization. Drilling is paused while BHEM
(Figure 4) is completed on drill holes DDH2405T003, DDH2405T004,
DDH2405T005 and DDH2405T006 to better establish the dip/plunge of
mineralization before the next round of drilling.
DDH2405T005, located up dip of (above) DDH2405T002 (Figure 3),
intersected weathered mineralization in the oxidized zone, where
mineralization is interpreted to be weathered away.
T5 mineralization remains open along strike, and down dip.
BHEM surveying is in progress (Figure 4).

DDH2405T006.
T11 Target
The T11 target is located proximal to the ultramafic footwall of
the Central Sector of the Luanga PGM+Au+Ni deposit. The pilot drill
hole (DDH2311T001, Figure 5) targeting the HeliTEM anomaly was
shown to be too shallow and was drilled up-dip of the EM conductors
which were subsequently better defined by BHEM to be deeper.
DDH2411T002 (Figure 5) targeted the center of this group of 10
conductors at a more appropriate depth, successfully intersecting
four zones of mineralization within an approximately 190m wide hydrothermal alteration zone.
Figure 6 shows the intersected mineralization, which consists of
four sulphide-rich intervals within the hydrothermal alteration
system. Mineralization presents as patches and veins, locally
reaching massive (Figure 1) to semi-massive textures. The main
sulphide paragenesis is pyrrhotite > pentlandite (Ni sulphide)
>> chalcopyrite (Cu sulphide), thus generating a strong EM
response made up of multiple conductors, which present as the four
sulphide-rich zones intersected. Assays are pending.

DDH2411T001. Location of drill holes DDH2411T001 and 002
At 96m depth drill hole
DDH2411T002 intersects the ultramafic footwall of the Luanga
deposit, intersecting an Fe-Ca alteration system which consists of
magnetite, grunerite, hornblende, actinolite, biotite and
almandine. This mineralogical assemblage is similar to other
IOCG-style mineralized systems that occur within the Carajás
Mineral Province, and is likely unrelated to the primary Luanga PGM
deposit mineralization which is at a stratigraphically higher
level. BHEM will be completed on DDH2411T002 prior to commencing
follow-up drilling.

Drill Results Status Update
A total of 304 drill holes have been completed to date by Bravo,
for 65,113 metres, including 8 metallurgical holes (not subject to
routine assaying). Results have been reported for 252 Bravo
drill holes to date. Assay results for 44 Bravo drill holes
that have been completed are currently outstanding (excluding the
metallurgical holes). Bravo plans to extend the current EM
drilling program from 3,000m to
8,000m, to continue drilling testing
and follow up drilling of EM anomalies.

Schedule 2: Assay Methodologies and QAQC
Samples follow a chain of custody between collection,
processing, and delivery to the SGS Geosol 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 Geosol 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.
