VANCOUVER, BC, May 28, 2024
/CNW/ - Bravo Mining Corp. (TSXV: BRVO) (OTCQX:
BRVMF), ("Bravo" or the "Company") has completed
initial drill holes on the "T5" and "T6" electromagnetic ("EM")
anomalies/targets. Assays have been received from the first drill
hole ("DDH") at target T5. Both targets are located east of the
original PGM+Au+Ni prospecting area of the 100% owned Luanga
palladium + platinum + rhodium + gold + nickel deposit
("Luanga" or "Luanga PGM+Au+Ni Project"), in the
Carajás Mineral Province, state of Pará, Brazil.
"Drilling of geophysical HeliTEM targets has identified
high-grade Iron Oxide Copper Gold style ("IOCG-style")
mineralization and represents a potentially significant high-grade
copper discovery. T5 is only one of eleven priority EM anomalies
hosted within the boundaries of the Luanga tenement. Moreover,
at the proximal EM target (T6), drilling has intersected
similar massive sulphide mineralization (assays pending)." said
Luis Azevedo, Chairman and CEO. "We
are very encouraged by the discovery of high-grade copper and
shareholders should be cognisant that Luanga is situated within the
world class Carajás IOCG province, an area very fertile for
high-grade copper discoveries. These results are a credit to
Bravo's highly skilled geology team who are only now beginning to
uncover the very exciting copper potential adjacent to Luanga's
Tier 1 PGM+Au+Ni deposit."
Highlights Include:
- Hole DDH2405T002 at target T5 intersected 11.48m of massive/semi-massive/breccia high-grade
copper sulphide mineralization grading 14.3% Cu, 3.3g/t Au
including 2.9m at 22.9% Cu, 3.6g/t Au
(Figures 1 and 2).
- High-grade copper in DDH2405T002 remains open at depth and
along strike.
- Drill hole DDH2405T004 (assays pending), completed
50m to the east of DDH2405T002, also
intersected 9m of
massive/semi-massive/breccia IOCG-style copper sulphide
mineralization (Figure 4).
- Presence of copper mineralization is consistent with
mineralization in the Carajás province where IOCG-style
mineralization is well established and high-grade discoveries are
not unusual.
- Such high-grade copper mineralization is likely unrelated to
the Luanga PGM+Ni+Au deposit 1km away.
- Drilling at T6 intersected 6m
of massive/semi-massive/breccia sulphides (assays pending), in this
case predominantly pyrrhotite. At this early stage, it appears to
be of a magmatic style, hosted in ultramafic rocks like those seen
in the footwall of the Luanga deposit. Follow-up drilling is
planned.
Exploration Drilling Update
Initial test diamond drilling of on Borehole Electromagnetic
Targets ("BHEM") targets T5 and T6 has been completed, and assay
results have been received from one of the holes at T5. Drill holes
are angled at -60 degrees, towards azimuths of 150-180° at T5 and
330-000° at T6. Together, this set of drill holes comprise a total
of 893 metres of diamond drilling.
Over the past 6 months, Bravo has conducted systematic
first-pass test drilling, coupled with BHEM on the priority EM
conductors identified by the HeliTEM survey. Although these
modelled conductors, generated by an airborne EM technique on
150m spaced lines, have a lower
degree of locational accuracy, they are sufficiently defined to
place first-pass drilling proximal to the conductor's location.
From there, BHEM, which provides more precise readings every
1m down the hole, has enabled
development of accurately located conductor models for follow-up
drilling.
From the 17 priority EM anomalies identified in the HeliTEM
survey (see press release September 11,
2023), Bravo has narrowed this list to 11 high priority
conductors that warranted follow-up drilling of predominantly
off-hole BHEM conductors. Drill testing commenced with the T5 and
T6 targets, which are respectively situated between 1km and 4km
east of the Luanga PGM+Au+Ni deposit.
T5 Target
Figure 2 shows the mineralization intersected and responsible
for the T5 conductor, consisting of massive/semi-massive/breccia
sulphides with sufficient pyrrhotite to generate a strong EM
response. The first hole (DDH2305T001, Figure 3), drilled with an
azimuth of 150°, targeted the HeliTEM conductor but only
intercepted a narrow interval of mineralization (0.7m grading 1.98% Cu). Subsequent detailed BHEM
modelling from this drill hole indicated that the conductor was
located to the west with a slightly different alignment. To
compensate, a new drill hole (DDH2405T002, Figure 3) was positioned
with an azimuth of 180°.

Drill hole DDH2405T002 intersected 11.5m (at 14.3% Cu, 3.3g/t Au) of
massive/semi-massive/breccia copper sulphide mineralization, at the
T5 target. The copper mineralization presents as being
within a hydrothermal system that overprints local felsic
meta-intrusive rocks (meta-tonalite). The main mineral assemblage
associated with this hydrothermal zone is represented by
calcium-amphibole, biotite-phlogopite, apatite and silica. The
sulphide paragenesis is that chalcopyrite is much more abundant
than pyrrhotite, forming massive and semi-massive zones associated
with brecciation within the hydrothermal zone.
Mineralization appears consistent with typical Carajás
IOCG-style mineralization (also supported by preliminary
chemistry from handheld XRF spectrometer). Numerous IOCG deposits
are well documented in the Carajás and several operating IOCG
copper-gold mines exist. The world-class Salobo Cu/Au mine (Vale
S.A.) is the most prolific.
The absence of magnetite alteration (which is commonplace in
Carajás IOCG deposits) is not unique, with several other Carajás
deposits similarly lacking magnetite. This results in the low
magnetic response as reflected in the detailed magnetic survey.
Historical soil geochemistry covers the T5 target with lines spaced
at 200 metres, however, with an east-west orientation, lines are
parallel to the modelled BHEM plates. Despite this, there is weak
Cu in soil anomalism in the vicinity of the BHEM plates (peak high
416ppm Cu) close to the eastern end of the BHEM model.
DDH2405T004 has also been completed (assays pending), while
DDH2405T003 is in progress.
Figure 4 shows core from the next drill hole (DDH2405T004) at
anomaly T5, completed 50m to the east
of DDH2405T002. Like DDH2405T002, this core also contains
9m of massive/semi-massive/breccia
IOCG-style copper sulphide mineralization (assays pending). This
finding supports the IOCG-style mineralization intersected in
DDH2405T002 to the west and appears to confirm the continuity of
the sulphide mineralization. The mineralization intersected at T5
remains open along strike and up and down dip from the intercepts
reported herein.
T6 Target
Figure 5 shows the intersected mineralization responsible for
the T6 conductor, consisting of 6m of
massive/semi-massive/breccia sulphides, predominantly pyrrhotite,
which generates a strong EM response. The first hole (DDH2306T001
Figure 6) was angled at an azimuth of 330° to target the
interpreted HeliTEM conductor but failed to intersect it.
Subsequently, BHEM identified the location of an off-hole
conductor, and follow-up drilling (DDH2406T002, Figure 6) at a new
azimuth of 000° intersected this conductor. At this early stage,
mineralization appears to be more likely of a magmatic style, with
low potassium, chlorine, and calcium, against an ultramafic
(dunite) footwall. Assays are pending, and follow-up drilling is
planned.
Drill Results Status Update
A total of 293 drill holes have been completed by
Bravo to date, for 62,811 metres, including 8 metallurgical holes
(not subject to routine assaying). Results have been reported
for 247 Bravo drill holes to date. Assay results for 38
Bravo drill holes that have been completed are currently
outstanding (excluding the metallurgical holes).
Bravo has initially budgeted a 3,000m of drilling to follow up the identified EM
anomalies and will continue to systematically evaluate the T5 and
T6 targets, as well as the other nine high priority conductors
defined by HeliTEM and subsequent BHEM.

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.
