VANCOUVER, Jan. 21, 2014 /PRNewswire/ - Brazil Resources
Inc. (the "Company" or "Brazil Resources") (TSX-V: BRI; OTCQX:
BRIZF) is pleased to announce that it has received National
Instrument 43-101 ("NI 43-101") resource estimates for each of its
São Jorge, Boa Vista and Surubim Gold Projects located in Pará
State, Brazil. The projects were
acquired by Brazil Resources through its acquisition of Brazilian
Gold Corporation ("BGC") in November
2013. The resource estimates confirm the historical
estimates completed by BGC as disclosed by the Company in its press
release dated November 22, 2013.
São Jorge Gold Project
Brazil Resources engaged Coffey Mining Pty Ltd.
("Coffey") to prepare an NI 43-101 resource estimate on the São
Jorge Project (the "São Jorge Estimate"). The São Jorge Estimate
has an effective date of November 22,
2013 and provides the following estimates for the project
(oxide and primary mineralization) at various cut-off grades (the
oxide resource comprises a small part (approximately 9%) of the
overall resource):

The São Jorge Estimate was based on a block
model of the deposit. Coffey classified the resource estimate as an
indicated or inferred mineral resource based upon the confidence of
the input data, geological interpretation and grade estimation.
Indicated and Inferred Mineral Resources are reported at a cut-off
grade of 0.3 g/t Au, which is estimated by Coffey based upon
economic estimates, process recovery, government taxes, other
expenses and a gold price of US$1,300/oz. The São Jorge Estimate is based on
37,154 m (145 holes) of diamond drilling completed by previous
operators, including 14,708 m (37 holes) of diamond drilling
completed by BGC since late 2010. Gold assays (19,590) were
composited at 1 m lengths and interpolated into the block model
using multiple indicator kriging. A three-dimensional solid model
of the sulphide and oxide mineralization was constructed to
constrain the resource estimate. The block model is comprised of
individual blocks measuring 5 m by 5 m by 5 m and grade is
interpolated into these blocks using multiple indicator kriging.
The above estimates may not reconcile due to rounding. No
additional material exploration work has been completed on the
project by the Company.
The São Jorge Estimate was prepared for Brazil
Resources by Porfirio Rodriquesz, B.Sc. (Min Eng.), MAIG and Leonardo de Moraes Soares, B.Sc (Geo), MAIG of
Coffey, who are qualified persons as defined under NI 43-101, are
independent of the Company and have reviewed and approved the
disclosure regarding the São Jorge Estimate above.
Boa Vista Gold Project
The Company has received an NI 43-101 resource
estimate respecting the VG1 deposit (Boa Vista Gold Project),
located in Pará State in northern Brazil (the "Boa Vista Estimate"), with an
effective date of July 3, 2012. The
following tables set out the Boa Vista Estimate (oxide and primary
mineralization) at various cut-off grades (the oxide resource
comprises a small part (approximately 1.3%) of the overall
resource):

The Boa Vista Estimate was based on shallow
(<150m depth) and limited drilling (15 holes in 3,007m) and 14
trenches (2,299 m) containing 3,399 assays. The drill holes
intersected a west-northwest striking, steeply dipping mineralized
zone that is up to 85 m in thickness and extends at least 150 m
below surface based on existing drilling. The mineralized zone
consists of quartz-pyrite stockwork and silicified zone(s) that are
hosted within a foliated, mixed mafic volcanic and intrusive unit
at or adjacent to granite rocks. Gold assays were composited at 5 m
lengths and interpolated into the block model using ordinary
kriging. A three-dimensional solid model of the primary and oxide
mineralization was constructed to constrain the resource estimate.
12 of the 15 diamond drill holes and 6 of the 14 trenches
penetrated these solids over a strike length of 500 m and were used
in the resource estimate. The block model is comprised of
individual blocks measuring 20 m by 20 m by 5 m with the long
dimensions of the block orientated east-west and down dip. At the
time of the Boa Vista Estimate no economic studies have been
completed on the project and, as a result, an economic cut-off is
unknown. No additional material exploration work has been completed
on the project by the Company.
The Boa Vista Estimate was prepared for Brazil
Resources by Jim Cuttle, B.Sc., P. Geo, Gary Giroux, MAsc., P. Eng. and Michael Schmulian, Bsc (Hons), Msc, FAusIMM, who
are qualified persons as defined under NI 43-101, are independent
of the Company and have reviewed and approved the disclosure
regarding the Boa Vista Estimate above.
Surubim Gold Project (previously called Rio Novo project)
Brazil Resources has received an NI 43-101
resource estimate (the "Surubim Estimate") respecting the Surubim
Gold Project, located in Pará State in northern Brazil, with an effective date of April 15, 2012. The following table sets out the
Surubim Estimate at various cut-off grades:

The Surubim Estimate was based on a total of 20
drill holes containing 2,978 gold assays. Gold assays were
composited at 2.5 m lengths and interpolated into the block model
using ordinary kriging. A three dimensional solid model of the
mineralization was constructed to constrain the resource estimate.
The block model is comprised of individual blocks measuring 20 m by
20 m by 5 m with the long dimensions of the block orientated
east-west and north-south. No economic studies have been completed
on this property and, as a result, the economic cut-off is unknown.
A gold cut-off of 0.3 g/t was highlighted in the estimate as a
possible open pit cut-off. No additional material exploration work
has been completed on the project by the Company.
The Surubim Estimate was prepared for Brazil
Resources by Jim Cuttle, P. Geo and Gary
Giroux, P. Eng., who are qualified persons as defined under
NI 43-101, are independent of the Company and have reviewed and
approved the disclosure regarding the Surubim Estimate above.
Technical reports respecting each of the above
resource estimates will be filed under the Company's profile on
SEDAR in due course. There is no new material scientific or
technical information respecting each of the above projects since
the effective date of their respective resource estimates.

Cautionary Note
Investors are cautioned not to assume that any
part or all of mineral deposits in the "indicated" and "Inferred"
categories will ever be converted into mineral reserves with
demonstrated economic viability or that inferred mineral resources
will be converted to the measured and/or indicated categories
through further drilling. In addition, the estimation of
inferred resources involves far greater uncertainty as to their
existence and economic viability than the estimation of other
categories of resources. Under Canadian rules, estimates of
Inferred Mineral Resources may not form the basis of feasibility or
other economic studies.
