Batero Gold Reports Additional Metallurgical Results from La Cumbre Deposit

Marketwired Canada
Batero Gold Corp. ("the Company") (TSX
VENTURE:BAT)(PINKSHEETS:BELDF)(FRANKFURT:68B) is pleased to report additional
metallurgical test results from the La Cumbre deposit ("La Cumbre"), one of
three porphyry deposits at the Company's 100% owned Batero-Quinchia project
("Project") located in Risaralda, Colombia. Positive metallurgical testing
yielded gold recoveries of 93% and 94% within 24 hours for mineralization in the
oxide zone and recoveries from 82% to 86% within 48-72 hours in the Transitional
Zone at La Cumbre. Column leach testing is scheduled to commence in August,
2012.
This initial metallurgical test work is part of the 2012-2013 work program
designed to evaluate the most efficient and cost effective leach processing
circuit for a potential starter pit of the near and at surface higher-grade
oxidized gold mineralization at La Cumbre.
"In addition to confirming the high recovery of 94% reported from our
preliminary testing of the oxide zone at La Cumbre, we are pleased to report new
recoveries of up to 86% in the Transitional Zone. We had no previous testing of
the Transitional Zone and these results are consistently above the 80% average
recovery used in our initial resource estimate reported February 2012," stated
Brandon Rook, President and CEO of the Company. "The results of these and
additional bottle roll tests will be compared and correlated with the results of
future column tests in order to estimate recoveries throughout the volume of
high grade mineralization at the La Cumbre deposit."
A sample selection and test work schedule is being finalized for additional
metallurgical test work on both the oxide and Transitional Zones to support a
potential starter pit operational scenario. Drilling from the currently underway
2012-2013 work program will provide sample material for metallurgical column
leach testing in order to provide additional recovery estimates and to determine
an optimum process flow sheet for the mineralization at La Cumbre.

and Transitional Zone at: http://media3.marketwire.com/docs/bat726-F1.pdf.

Metallurgical Testing
Metallurgical testing undertaken by C.H. PLENGE & CIA. S.A on behalf of the
Company was completed on seven drill core composite samples from the 2011 drill
program to determine their response to cyanidation via bottle roll tests. The
composite samples were selected to represent mineralization in both the oxide
and Transitional Zone at La Cumbre and over the current known length of the
deposit. These results are consistent with the original tests of the oxide
material presented in the Company's NI 43-101 resource estimate technical report
(April 19, 2012).
The oxide horizon exists at surface to a depth up to 70 metres. The thicker
Transitional Zone (horizon), over a vertical distance of 150 metres to 200
metres, is below the oxide horizon and has a low total sulphur content. The
composite head grades were selected to represent an average deposit grade at a
0.5 g/t gold cut-off, or approximately 0.7 g/t gold grade and in cases higher
grade material representing central core (1 g/t gold). All samples comprised
drill core pulps meeting over 80% passing a 200 mesh size (about 75 microns).
Results presented in the table above are the recoveries after 72 hours. For the
oxide horizon sample gold recoveries of 90% were achieved in all samples within
24 hours, whereas for the Transitional Zone samples at least 80% gold recovery
was achieved within 48 hours.
Preliminary metallurgical testing was completed by G&T Metallurgical Services in
2011 on six drill core composite samples from the 2010-2011 drill program.
La Cumbre Highlights:
-- At and near surface oxidized gold mineralization grading greater than
0.7 g/t
-- Lateral and vertical continuity of gold mineralization
-- Topography and location of gold mineralization support a low strip ratio
-- Negligible deleterious chemical elements associated with the gold
mineralization
-- Environmental and social baseline studies are ongoing
-- Permitting process to initiate exploitation activity is ongoing
-- Basic infrastructure in place including road access, power and water
-- 100% ownership of surface rights over La Cumbre deposit
The 2012-2013 work program at La Cumbre will include up to 6,000 metres of
diamond drilling (2,000 metres contracted), comprehensive metallurgical testing,
geotechnical studies, environmental studies, and social baseline studies and
permitting, which will determine the optimum starter pit production scenario.
