BGC Now Has a Total Indicated Resource of 541,000 Ounces Grading 1.2
G/T Gold and Inferred Resource of 1,497,000 Ounces Grading 0.8 G/T Gold
at a 0.3 G/T Cut-Off on Three Projects in Brazil
VANCOUVER, British Columbia -- (Business Wire)
Brazilian Gold Corporation (TSXV: BGC) is pleased to report the updated
NI43-101 compliant mineral resource for the São Jorge gold deposit that
includes 14,230,000 t grading 1.18 g/t gold (541,000 oz) in the
indicated category and 27,810,000 t grading 0.68 g/t gold (611,000 oz)
in the inferred category at a 0.3 g/t cut-off. The estimate incorporates
an additional 14,393 m (38 holes) of diamond drilling completed by
Brazilian Gold in 2011 as compared to the previous estimate that was
based on 22,762 m (110 holes) of diamond drilling completed by the
previous operators. The mineral resource estimate was completed by
Coffey Mining (Coffey) of Toronto, Ontario and is documented in an
independent NI43-101 Technical Report that will be posted on our website
and SEDAR within 45 days of this News Release.
The wholly owned São Jorge property (585 km2) is well
situated with respect to infrastructure that includes hydro-electric
power, a paved highway 3 km due east of the deposit, and a skilled
workforce in the nearby town of Novo Progresso located 70 km to the
south.
Highlights
-
Indicated ounces have increased by 43% (partly reflecting an 18%
increase in indicated grade) when compared to the previous resource
estimate in the 2011 Preliminary Economic Assessment (PEA) by Coffey
both of which were reported at a 0.3 g/t gold cut-off.
-
At a 0.5 g/t gold cut-off grade, the indicated gold grade increases to
1.40 g/t gold (Table 1) with a total of 465,000 contained ounces.
-
Inferred ounces have increased 9.5% (partly reflecting a 35% increase
in tonnage) when compared to the 2011 PEA.
-
Selective mining of internal waste in the deposit and diverting this
tonnage to a surface stockpile may result in an increase in the head
grade delivered to the process plant.
-
Potential robust operating margin suggested by the insitu metal value
of US$67/tonne (indicated resource grade of 1.18 g/t and gold price of
$1,765/oz) and the 2011 PEA operating cost of US$16.36/tonne; (note
mineral resources that are not mineral reserves do not have
demonstrated economic viability).
-
An untested 1.5 km long resistivity +/- chargeability anomaly
southeast of the São Jorge deposit is similar to the geophysical
signature over the deposit suggesting potential to find additional
zones of gold mineralization to the southeast; potential to find new
gold deposits on the largely unexplored São Jorge property is
considered excellent.

Strong mineral inventory growth on our three most advance stage
projectsâSão Jorge, Surubim (Jau) and Boa Vista (VG1); see Tables 2
and 3.
Ian Stalker, CEO of Brazilian Gold, commented, âWe are delighted with
the results of the updated independent resource estimate on the São
Jorge deposit. The increase in tonnage and grade of the indicated
resource suggests that significantly more ounces will fall within the
pit shell as compared to the 2011 PEA, as well as the increase in the
inferred ounces that will fall into the same mining inventory.
âIn addition, as identified by the recent drilling and more detailed
geological interpretation of the deposit, there is potential to increase
the overall deposit grade by selectively mining the low grade internal
waste and diverting it to a surface stockpile instead of sending it
through the process plant.
âThe updated resource numbers along with recently completed
metallurgy, power studies, environmental assessments, as well as the
depreciation of the Brazilian 'Real' will be incorporated in an updated
PEA, which should result in substantially better economics than the
previous more than acceptable PEA results, and will make the decision to
move to production more compelling.
âFinally, with the recently identified geophysical anomaly located
directly southeast of the deposit and extending for greater than 1.5 km,
the potential to find additional zones of gold mineralization makes us
even more confident about the future development of our São Jorge
Project in Brazil.â
The São Jorge resource estimate is based on 22,762 m (110 holes) of
diamond drilling completed by the previous operators and 14,393 m (38
holes) of diamond drilling completed by Brazilian Gold since acquiring
the project in 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 primary 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. The mineral resource estimate (oxide and primary mineralization) at
various cut-off grades is shown in Table 1; the oxide resource comprises
a small part (9 %) of this overall resource. A Preliminary Economic
Assessment (PEA) on the São Jorge deposit was completed in June 2011,
which indicates an economic open pit cut-off grade of 0.3 g/t gold using
a gold price of US$1,300 and economic parameters as outlined in the
report.

sulphide)* at various cut-off grades.

*According to National Instrument 43-101 and CIM (2005) an âInferred
Mineral Resourceâ is that part of a Mineral Resource for which quantity
and grade or quality can be estimated on the basis of geological
evidence and limited sampling and reasonably assumed, but not verified
geological and grade continuity. The estimate is based on limited
information and sampling gathered through appropriate techniques from
locations such as outcrops, trenches, workings and drill holes. Due to
the uncertainty that may be attached to Inferred Mineral Resources, it
cannot be assumed that all or any part of an Inferred Mineral Resource
will be upgraded to an Indicated or Measured Mineral Resource as a
result of continued exploration. Confidence in the estimate is
insufficient to allow the meaningful application of technical and
economic parameters or to enable an evaluation of economic viability
worthy of public disclosure.
The São Jorge deposit is approximately 1,400 m long by up to 200 m wide
and has been intersected in drill holes to 350 m depth; the deposit
strikes northwest and has a sub-vertical dip. The deposit is hosted in
quartz monzogranite and mineralization appears to be spatially
associated with a number of discontinuous shear and fracture zones.
Alteration minerals included chlorite, epidote, sericite, silica and
sulphides that occur along fractures or where the fracture density is
high as pervasive alteration. The predominant sulphide is pyrite with
minor amounts of chalcopyrite. Gold mineralization is commonly
associated with silica-sericite-sulphide alteration and higher gold
values are generally associated with higher pyrite content and the
presence of chalcopyrite.
Porfirio Cabaleiro, B.Sc., (Mining Engineer), MAIG and Hebert Oliveira,
B.Sc. (Geology), MAIG, are the Qualified Persons for the NI43-101 Report
on the Resource Estimate of the São Jorge gold deposit and have reviewed
and approved the contents of this press release as far as it relates to
their work.
Garnet Dawson, M.Sc., P.Geo. (British Columbia), Vice President,
Exploration for the Company and a Qualified Person, as defined by

disclosure contained in this News Release.

Brazilian Gold is a Canadian-based public company with a focus on the
acquisition, exploration and development of mineral properties in
northern Brazil. The Company has title to one of the largest land
packages (3,753 km2) in the Tapajós and adjacent Alta
Floresta gold provinces. The land package contains green fields to more
advance stage projects including the Companyâs flagship São Jorge
project. Rapid improvements to regional infrastructure continue to
provide underlying support to Brazilian Goldâs activities in northern
Brazil.
