Result is the thickest interval of
continuous PGM+Au mineralization to date at Luanga
VANCOUVER, BC, April 18,
2023 /CNW/ - Bravo Mining Corp. (TSXV: BRVO) (OTCQX:
BRVMF), ("Bravo" or the "Company") announced
that it has received assay results from a further ten diamond
infill 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.
"New results from Luanga's infill drilling completed in 2022
continue to encourage, comparing well with historic drilling on
nearby drill sections, and to previously reported results from
Bravo's drilling on the same drill sections. DDH22LU100 from the
North Sector is now the thickest known interval of continuous
PGM+Au mineralization to date in the Luanga deposit. DDH22LU122
(North Sector) and DDH22LU123 (Central Sector) show continuing
evidence of increasing levels of magmatic nickel (± copper)
sulphide mineralization as drilling approaches the footwall
ultramafic sequence," said Luis
Azevedo, Chairman and CEO of Bravo. "We look forward
to advancing the Phase 2 program of extensional drilling, probing
deeper into the Luanga deposit."
Highlights Include:
- Assay results received from drilling at all three Sectors of
the Luanga deposit 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.
- With a downhole thickness of 115.6m from surface, DDH22LU100 has intersected
the thickest known interval of continuous mineralization to date
within the Luanga deposit.
- A geophysical contractor is expected to start the HeliTEM
(Helicopter Electromagnetic) survey over the entire Luanga project
in May 2023. Surface
micro-gravity and detailed ground magnetics are in
progress.
- The surface trenching program will recommence in
Q2.

Luanga Drilling Assay Results Update
A total of 169 drill holes (34 in 2023) have been completed by
Bravo to date, for 29,393 metres, including all 8 planned twin
holes and all 8 metallurgical holes (not subject to routine
assaying).
The Phase 1 drilling program has concluded, and the Phase 2
program has commenced (Figure 1).
Results have been reported for 119 Bravo drill holes
to date. Excluding the metallurgical holes, results for
42 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 to previously reported results from Bravo
drilling on the same drill sections (see Sections 1 and 2).
Drill results were received for four drill holes in the North
Sector and continue to show multiple stacked zones of
mineralization, as reported in previous news releases. DDH22LU100
is an exception to this, intersecting 115.6m of continuous mineralization from surface
(the thickest mineralized interval intersected to date at Luanga),
followed by narrow zones of seemingly unrelated copper (±gold)
mineralization at depth. DDH22LU122 (North Sector) also returned
narrow intervals of magmatic nickel/copper sulphide mineralization
at depth, adding further evidence to the potential for magmatic
nickel (± copper) sulphides at depth.
Drill results were received from five infill drill holes from
the Central Sector and, as has been reported previously,
mineralization is more typically dominated by one thicker zone of
mineralization. Results in the Central Sector also continue to
compare well with intercepts in historic drilling on neighbouring
drill sections, and to shallower (up-dip) drilling (DDH22LU040 and
044, Figure 2 – Section 1) by Bravo on the same section.
It is worth noting again that the Luanga intrusion has been
turned on to its side. In the Southwest and Central Sectors Luanga
has been rotated beyond vertical (I.E., is overturned), such that
the basal (footwall) ultramafic sequence lies geographically above
the known PGM+Au+Ni deposit. DDH22LU123 (Section 1) is a good
example of Bravo's drilling first needing to pass through
ever-increasing thicknesses of the footwall ultramafic sequence to
reach the interpreted down-dip extensions of the Luanga PGM+Au+Ni
deposit. As shown on the section, zones of magmatic nickel
sulphides continue to be present in the footwall ultramafic. Figure
3 (DDH22LU123) shows a typical example of Harzburgite ultramafic
containing disseminated magmatic nickel sulphides.
DDH22LU119 (Figure 4 – Section 2) was the only drill hole in
this group of results from the Southwest Sector, with
results comparing well with intercepts in historic drilling on
neighbouring drill sections and comparing favourably to up-dip
drilling (DDH22LU114) by Bravo on the same section.
Phase 2 Drill Program
The Phase 2 program has commenced, with 21,500 meters of
drilling planned, focused on extensional drilling to depth (below
the known mineralization) and exploration of new targets.
The extensional drilling seeks to follow the known Luanga
PGM+Au+Ni mineralization down-dip while, at the same time,
extending holes to depths sufficient to test the interface between
the PGM host sequence and the ultramafic footwall sequence.
The Phase 2 program also includes a significant budget
allocation for exploration, with an accelerated geophysical program
aimed at generating magmatic nickel sulphide exploration targets
and examining the entire Luanga project area, including areas
outside the mineralized footprint identified to date.
A geophysical contractor is expected to start the HeliTEM
(Helicopter Electromagnetic) survey over the entire Luanga project
in May 2023. They are currently
working on mobilization and permits.
Surface geophysical programs, micro-gravity and detailed ground
magnetics, are now both in progress at Luanga.

unrelated", "evidence", "expected", "better define", "interpret",
"seek", "potential", "variants of these words and
other similar words, phrases, or statements that certain events or
conditions "will" or occur. This news release contains
forward-looking information pertaining to the Company's ongoing
drill and trenching programs and the results thereof; 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 copper) and the potential for
extensions to depth; the interpretation that Ni grades increase in
the basal portions of the intrusion 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

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.
