Belo Sun Reports Positive Results From Preliminary Metallurgical Leach Test Work Conducted With Volta Grande South Block Samples

Belo Sun Reports Positive Results From Preliminary Metallurgical Leach Test 
Work Conducted With Volta Grande South Block Samples With
Average Recoveries of 95% and Reports AGM Results 
TORONTO, ONTARIO -- (Marketwired) -- 05/23/13 -- Belo Sun Mining
Corp. (TSX:BSX) has received positive results from preliminary
metallurgical leach test work conducted with samples from the South
Block deposit of its 100% owned Volta Grande Gold Project located in
Para State, Brazil. 
The purpose of this preliminary metallurgical test work program was
to verify if the South Block ore is amenable to the same optimum
leach process conditions recently confirmed for the Grota Seca and
Ouro Verde deposits. The South Block composite samples were tested at
a grind size of 80% passing 75 microns, slurry density of 40% by
weight, 0.5 g/L NaCN concentration, 10 ppm dissolved oxygen
concentration and at a pH of 10.5.  
A total of six South Block composite samples were tested. Head grades
varied from 2.2 g/t Au to 6.5 g/t gold with an average gold recovery
of 95%. These results are consistent with previous results of 94%
gold recovery recently reported for the Ouro Verde and Grota Seca
Omar Antunes, Metallurgy Manager for the Volta Grande Project,
commented: "These preliminary metallurgical leach test work results
indicate that the ores from Grota Seca, Ouro Verde and South Block
deposits can all be blended and treated in the same plant under the
same optimum process conditions while achieving excellent gold
recoveries. We are very pleased to be able to report such excellent
results for the South Block deposit." 
The last mineral resource for "South Block" was released on December
18, 2012 (see press release) with an inferred pit constrained
resource containing 5,368,000 tonnes at an average grade of 2.73 g/t
Au containing 471,000 ounces of gold, and an inferred underground
mineral resource of 408,000 tonnes at an average grade of 3.89 g/t Au
containing 51,800 ounces for gold. Since this mineral resource was
released Belo Sun has drilled 62 holes totalling 14,275 meters on the
South Block. These drill holes will be incorporated in an updated
mineral resource for the whole project to be released to the market
at the beginning of the next quarter which also incorporates 47 holes
totalling 8,750 meters at Ouro Verde and Grota Seca and it is
anticipated this updated mineral resource will be incorporated in the
feasibility study that Belo Sun anticipates completing at the end of
Mark Eaton President and CEO stated "We are very encouraged with
these metallurgical results which demonstrate the ability to add the
higher grade South Block material to the existing planned Volta
Grande material through the companies processing facility". 
The results reported in this news release are from test work
performed in Santiago de Chile by SGS Minerals S.A. The test work was
directly supervised by Sebastian Bravo, process supervisor and by
Catherine Souza, head engineer in charge of the Volta Grande Project.
SGS Technical Manager Dr. Heriban Soto, coordinated the laboratory
work. The test results reported have been reviewed by Omar Antunes,
Metallurgy Manager for the Volta Grande Project.
