VANCOUVER, BC, Sept. 27,
2022 /CNW/ - Bravo Mining Corp. (TSXV:
BRVO), ("Bravo" or the "Company") today
announced that it has received results from the re-analysis of
samples from an additional eight historic diamond drill holes
("DDH") from its wholly owned Luanga palladium + platinum + rhodium
+ gold + nickel project ("Luanga" or "Luanga
PGM+Au+Ni"), located in the Carajás Mineral Province, state of
Pará, Brazil.
"With re-assay results received from 36 historic drill
holes to date, an emerging positive trend has been observed in
respect of overall PGM+Au grades, with greater than 80% of
re-assay intersections received to date returning better grades as
compared to historic results of approximately 20 years ago."
said Luis Azevedo, Chairman and CEO
of Bravo. "We will continue to assess this emerging grade trend as,
if maintained in the remaining holes to be re-assayed, it could
clearly have a positive impact on future mineral resource
estimates.
Highlights
- Assay results from the re-assaying of samples from historic
drilling continue to correlate closely with the historic assay
results, in both tenor and mineralized thicknesses, but with the
grade of more than 80% of the re-assayed intercepts exceeding the
historic intercepts over comparable thicknesses.
- Highlights of Bravo's most recent re-assay results are
tabulated below, with details and comparisons attached:

- 77 drill holes have been completed, for a total of 13,051
metres (or 51% of Phase 1 Drilling Program). Currently, samples
from 30 drill holes are at the laboratory pending results.
- 12,632 samples submitted for assay to date including 2,945
re-assay samples from historic drill core.
- 6 drill rigs operating onsite.
Luanga Re-Assay and Phase 1
Drilling Progress
A comparison of the historic intercepts with the Bravo re-assay
results is tabulated below, with a plan showing their locations and
drill sections provided for (PPT-LUAN-) FD0035, FD0053, and FD0071.
Bravo's re-assay results continue to closely correlate to the
historic intercepts, in both thicknesses and grade. Importantly,
the grade of the re-assayed intercepts exceeds that of the historic
intercept over comparable thicknesses in over 80% of the intercepts
re-assayed to date. This is most likely related to improved assay
methods for PGMs versus those available over 20 years ago.
The Phase 1 diamond drill program continues as planned at
Luanga. Six drill rigs are on site, with drilling progressing in
various locations along the entire 7km strike length of the known
Luanga mineralized envelope (as defined by historic drilling). To
date, 77 drill holes have been completed, for a total of 13,051
metres of the planned 25,500 metre Phase 1 drill program.

About Bravo Mining Corp.
Bravo is a Canada and
Brazil-based mineral exploration
and development company focused on advancing its Luanga PGM + Au +
Ni Project in the world-class Carajás Mineral Province of
Brazil.
The Luanga Project benefits from being in a location close to
operating mines, with excellent access and proximity to existing
infrastructure, including road, rail and clean and renewable hydro
grid power. The project area was previously de-forested for
agricultural grazing land. Bravo's current Environmental, Social
and Governance activities includes replanting trees in the project
area, hiring and contracting locally, engagement with local
communities, and ensuring protection of the environment during its
exploration activities.
Technical Disclosure
Technical information in this news release has been reviewed and
approved by Simon Mottram, F.AusIMM
(Fellow Australia Institute of Mining and Metallurgy), President of
Bravo Mining Corp. who serves as the Company's "qualified person",
as defined in National Instrument 43-101 Standards of Disclosure
for Mineral Projects ("NI 43-101"). Mr. Mottram has
verified the technical data and opinions contained in this news
release.
Forward Looking
Statements
This news release contains forward-looking information which
is not comprised of historical facts. Forward-looking information
is characterized by words such as "confident", "highly encouraged",
"confirm", "correlate", "success", "high-grade", "estimated",
"potentially", "emerging positive trend" and other similar words,
phrases or statements that certain events or conditions "could",
"should", or "will" occur. In particular, this news release
contains forward-looking information pertaining to the Company's
ongoing re-assay and drill programs and the results thereof; the
potential for a continued increase in grades relative to historic
assays and the possible impact on future mineral resource estimates
the potential for the definition of new styles of mineralization
and extensions to depth 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, 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 considered reasonable
as of the date hereof, including, but not limited to, the
assumption that the assay results confirm the interpreted
mineralization contains significant values of nickel, copper and
also contain PGMs and Au; final drill and assay results will be in
line with management's expectations; that re-assayed may continue
to outperform historic grades; that activities will not be
adversely disrupted or impeded by regulatory, political, community,
economic, environmental and/or healthy and safety risks; that the
Luanga Project will not be materially affected by potential supply
chain disruptions; and general business and economic conditions
will not change in a materially adverse manner. Although the
Company believes that the assumptions and factors used in preparing
the forward-looking information in this news release are
reasonable, undue reliance should not be placed on such
information. The Company disclaims any intention or obligation to
update or revise any forward-looking information, other than as
required by applicable securities laws.

Schedule 2: Assay Methodologies
and QAQC
Samples followed chain of custody between collection, processing
and delivery to the ALS laboratory in Parauapebas, state of Pará,
Brazil. The drill core was
delivered to the core shack at Bravo's Luanga site facilities and
processed by geologists who inserted certified reference materials,
blanks and duplicates into the sampling sequence. Drill core was
quarter cut and placed in secured polyurethane bags, then in
security-sealed sacks before being delivered directly from the
Luanga site facilities to the Parauapebas ALS laboratory by Bravo
staff. Additional information about the methodology can be found on
the respective ALS or SGS global websites (ALS, 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.
