The 100% owned Volta Grande Project is located approximately 60
kilometres southwest of the town of Altamira (pop. 100,000) in the
northern region of Para State. The geological setting (
Tres Palmeiras greenstone belt)
at the project area is part of the same sequences present in the
Carajas "World Class" mineral province. The Company currently controls
the mining and exploration rights over an area covering 130,541
hectares(1,305 sq. km) of the area known for artisanal gold mining.

Exploration Activities
In order to prepare the Volta Grande Project for a Definitive
Feasibility Study which will commence in Q4 of 2013, Belo Sun launched a
large diamond drill program in mid 2010 with the aim of upgrading and
expanding the projects resources. Since drilling commenced in 2010, Belo
Sun has increased the Measured & Indicated Resources to 4.7M oz/Au
with an average grade of 1.68 g/t Au, Inferred Resources to 2.4M oz/Au
with an average grade of 1.93 g/t Au. Additionally, drill results
continue to confirm the potential for further increasing the resources
at Volta Grande.

Notes:
The effective date of the audited mineral resource statement is April
15, 2013. Mineral resources are not mineral reserves and do not have
demonstrated economic viability. All figures have been rounded to
reflect the relative accuracy of the estimates.
Open
pit mineral resources are reported at a cut-off grade of 0.5 g/t gold,
and underground mineral resources are reported at a cut-off grade of 2.0
g/t gold. Cut-off grades are based on a number of parameters and
assumptions including gold price of US$1,400 per troy ounce, 94%
metallurgical gold recovery for weathered and unweathered rock, open pit
mining costs of US$1.41/tonne, process costs of US$11.98/ tonne,
General & Administrative costs of US$2.89/tonne and selling costs
(refining, transport, insurance and environment) of US$ 13.82 per troy
ounce.
The
quantity and grade of the reported inferred mineral resources are
uncertain in nature and there has been insufficient exploration to
define the inferred mineral resources as indicated or measured mineral
resources and it is uncertain if further exploration will result in
upgrading them to an indicated or measured mineral resource category.
The
mineral resources have been classified according to the Canadian
Institute of Mining, Metallurgy and Petroleum Definition Standards for
Mineral Resources and Mineral Reserves (November 2010).
Volta Grande Infrastructure
The Volta Grande Project is endowed with excellent access to
established infrastructure. The project is located 60 kilometers from
the city of Altamira which has a population of approximately 95,000 and
an airport with regularly scheduled commercial flights. The project can
be accessed from Altamira either by river or by road - both options are
suitable for the transport of necessary equipment. The city of Altamira
is also equipped with a 230 kilowatt transmission line from which the
project will draw its power for the first years of production. Volta
Grande itself is situated alongside the Xingu river's "Big Bend" (or the
"Volta Grande") upon which the Brazilian government has begun
construction the world's third largest hydro-damming facility - the Belo
Monte Hydro Dam

Property History
Exploration for gold deposits in the Volta Grande area of the eastern
Amazon region of Brazil dates back to the Portuguese Conquests of the
16th century and has since continued sporadically to the present.
Initial discovery of gold at the Volta Grande (Big Bend) site is
believed to have been made in the early 1900s.
Mining by Garimpeiros (Artisanal Miners)
Many parts of the Volta Grande Property have been mined in the past
by garimpeiros (artisanal miners). From the 1960s to late 1990s, the
average grade of material extracted from numerous small alluvial gold
deposits of the area is reported to be up to 3 oz/ton gold (anecdotal
reports from local garimpeiros). These included the Ouro Verde, Gaúcho,
Canela, Serrinha, Grota Sêca, Galo, Japão, Nobelino, and other workings
by garimpeiros near the village of Itatá. Some of these garimpeiro
workings are still active.

Regional Geology
The Volta Grande Project area is situated along the northern boundary
of the Carajas-Iricoumé Block of the Eastern Amazonian Craton. In this
part of the Amazonian Craton, the regional structures have a
northwesterly trend. In the area west of Belém, the southern segment of
the Amazonian Craton is underlain by east-northeasttrending Phanerozoic
cover rocks of the Amazon Basin.

Local Geology
The Volta Grande property is situated along a major ductile
deformation zone within the west-northwest trending Três Palmeiras
greenstone belt. It is underlain by west northwest trending and steeply
south dipping gneisses of metasedimentary and/or metavolcanic origin and
syntectonic diorite.
