Highlights include 79m at 3.65g/t PGM+Au, including 22m at 9.40g/t PGM+Au; 125m at 2.30g/t PGM+Au; and 175m at 1.71g/t PGM+Au, including 30m at 3.47g/t PGM+Au
VANCOUVER, BC, Sept. 26,
2023 /CNW/ - Bravo Mining Corp. (TSXV: BRVO) (OTCQX:
BRVMF), ("Bravo" or the "Company") announced
that it has received assay results from a further five trenches,
all located in the North Sector 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.
"Our trenching program continues to yield outstanding results
and highlights the lateral extension of Oxide PGM+Au mineralization
at surface, now observed in both the North and Southwest Sectors.
Results show the potential for increased volume and improved
average grades in the oxide zone, which are expected to have a
positive impact on the oxide component of the forthcoming Mineral
Resource Estimate," said Luis
Azevedo, Chairman and CEO of Bravo. "Furthermore, the
assay grades returned within the trenches are consistently higher
than the assay grades in the nearest drill holes located below the
trenches. This supports our interpretation of supergene enrichment
occurring in the near-surface oxide zone."
Highlights Include:
- The successful program of trenching, which commenced at
Luanga's Southwest Sector, aimed at improving the
interpretation of mineralization at surface for the pending Mineral
Resource Estimate ("MRE"), continues to progress in the North
Sector, again returning excellent results and showing significant
upside potential in both volume and the grade of
mineralization.
- Further potential is yet to be tested since some trenches
are still in mineralization at their end/s and require extension.
For example, mineralization in trench TRC23LU022 is open at each
end of the trench, with both ends finishing in the highest-grade
mineralization within the greater 125m wide interval:
- 0m (Start of Trench) to
9m @ 5.62g/t PGM+Au; and
- 117m to 125.6m (End of Trench) @ 4.66g/t PGM+Au.
- Trenching is planned to continue along the entire 8.1km
strike length of the Luanga deposit.

Luanga Trenching Program
The successful program of trenching that commenced at Luanga's
Southwest Sector in 2022, has continued in the North Sector (Figure
1). Trenching across the strike of the outcrop/sub-crop aims to
better interpret near surface mineralization for the pending MRE,
and to reduce the distance/spacing between assay data points in
preparation for MRE classification (i.e., Indicated/Inferred).
The trenching program continues to highlight significant growth
in the extent of shallow mineralization, which is supported by
thicknesses intersected in shallow drillholes nearby. Assay results
from trenching (sections shown in Figures 2 & 3) clearly show
that mineralization in the saprolite zone (above the base of
oxidation) increases in thickness, a feature that is common
in tropical weathering profiles. Figure 4 shows the location of
trenches, and their mineralized thicknesses in plan. PGM grades in
the trench assay samples compare positively to the high-grade
intersections in nearby down dip drillholes (Figures 2 & 3).
This supports the concept of supergene enrichment in the saprolite
zone, as reported in previous trench results
(see May 08th,
2023).
The saprolite zone ranges from <2m thick on the ridge line, to 25m thick away from the ridge. When taking into
account the wider than expected high-grade trench results, the
evidence of near surface supergene enrichment and the Luanga
deposit's 8.1km of strike, there is potential for a substantially
greater volume of saprolite zone/oxide mineralization at higher
than historically modelled grades, and potentially greater metal
content in the pending maiden MRE.
The same sampling, assay laboratory procedures and QAQC
protocols as applied to drill core sampling are applied to trench
samples.
Trenching to date continues to be successful, beneficial, and
highly cost effective. Trenching is planned to continue along the
entire 8.1km strike length of the Luanga deposit, moving to the
Central Sector after completion in the North Sector.
Figure 2 (Section 1) shows how trenching has significantly
improved the definition and volume potential of near surface oxide
mineralization, while improving the understanding of the
relationship between near surface oxide mineralized intersections
in Bravo's drilling. Previously, the up-dip portion of the
mineralized section was interpreted more conservatively; however,
trench data provides strong support for an improved
interpretation.
In the case of trench TRC23LU022 (Figure 2), mineralization is
also still open at each end of the trench, signalling the potential
for further improvement when the trench is extended. Furthermore,
both ends of the trench finished in the highest-grade portions of
the trench: 0m (Start of Trench) to
9m grading 5.62g/t PGM+Au and
117m to 125.6m (End of Trench) grading 4.66 g/t
PGM+Au.
Trench TRC23LU024 (Figure 3, Section 2) was opened to evaluate
the previously interpretation of mineralization; however, it is now
clear that a significant blanket of mineralized oxide exists not
just on top of the ridge but persisting down both sides of the
ridge. With multiple zones of mineralization in the trench, one of
which is 175m wide, the trench's
extensions are yet to be tested in both directions. Assay grades
encountered in the trench are once again higher than assay grades
in nearest drill holes below the trench, further supporting
the existence of supergene enrichment in the near surface oxide
material.
In summary, firstly Bravo sees potential for MRE volume growth
due to a more extensive oxide blanket covering the entire ridge
coincident with the mineralized zone and extending down both sides
of the ridge. Secondly, Bravo sees further potential for volume
growth due the "mushroom" style expansion of mineralization in the
saprolite zone directly above the main mineralized zones and
extending beyond the trench limits. Further, there is the potential
to continue to encounter higher average grades in the oxide
mineralization due to the continuing evidence of supergene
enrichment near surface.
Luanga Drilling Status
A total of 215 drill holes (80 in 2023) have been
completed by Bravo to date, for 44,110 metres, including 8 planned
twin holes and 8 metallurgical holes (not subject to routine
assaying). Results have been reported for
186 Bravo drill holes to date. Results for 21
Bravo drill holes are currently outstanding (excluding the 8
metallurgical holes).

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.
