YAMANA GOLD INC. (TSX:YRI)(NYSE:AUY)(LSE:YAU) ("Yamana" or the "Company")
today announced further results from the 2012 exploration program at
Corpo Sul, the newly discovered mineralized zone located directly
adjacent to the main pit at Chapada, Brazil, one of the Company's
flagship operations. To date, 20,000 metres of diamond drilling has been
completed out of a total planned program of 27,000 metres.

    Results since the discovery of Corpo Sul, in 2011, have established the
zone as an extension of the main Chapada pit with grades in excess of
expected grades being mined in future years at the operation. The
discovery had previously been anticipated to supplement future throughput
at Chapada improving the future production profile. Recent results and
pace of discovery are now interpreted as being more significant. With
continued drilling at 200 metre spacing, along with the apparent
homogeneity of the mineralization, the Company has increased confidence
in the continuity of the higher grades and the eventual increased size of
Corpo Sul. 

    Since the Company's news release of June 5, 2012, 33 additional drill
holes have been completed on the southwest extension of Corpo Sul with
assays still pending on 19 of those holes. The additional drilling has
further defined the geometry and grade continuity of Corpo Sul from the
southwest limits of the 2011 mineral resource for an additional strike
length of 2.9 kilometres.

    Results from the most recently received assays include drill hole CS-73
which intersected 82.82 metres averaging 0.36 g/t gold and 0.40% copper
and 200 metres and 400 metres further to the north, respectively, drill
hole CS-100 returned 144.15 metres averaging 0.35 g/t gold and 0.40%
copper and drill hole CS-110 returned 144 metres averaging 0.44 g/t gold
and 0.34% copper including a higher grade core of 48 metres of 0.92 g/t
gold and 0.57% copper. All of these high grade intersections are within
700 metres of the current Corpo Sul mineral resource and will extend the
currently modeled mineral resource to the southwest.

    See Table 1 for a complete list of drill results received.

results to date for Corpo Sul can be found at

    To the southwest on section A0 (see Figure 1), drill hole CS-109
intersected mineralization thus extending the strike length of Corpo Sul
by approximately 400 metres to the southwest, increasing the known strike
length to just under 3 kilometres. The alteration and mineralization were
intersected deeper than anticipated suggesting a major fault has offset
the Corpo Sul deposit. Additional drilling will be required to better
understand the sense of movement and displacement which is planned as
part of the 2012 and 2013 exploration programs.

    The current drill results at Corpo Sul confirm the expansion of the
mineralized zone and continue the recent exploration success at Chapada
which commenced with Suruca in 2010 and Corpo Sul in 2011. Mineralization
and mineral resources have now been traced along a combined strike length
of almost 16 kilometres centered by the main Chapada pit. 

    These new discoveries have led to the initiation of a prefeasibility
study that is now underway, which will define the role of Suruca and
Corpo Sul in the future production at Chapada. This study is expected to
be completed by year end, and it is expected to include a new mineral
resource at Corpo Sul using the current drilling information. Corpo Sul
is expected to initially contribute higher grade ore to Chapada and it
will eventually be considered, depending on its size, as a stand alone
ore body.

    In 2013, the Company expects to begin evaluating the area to the
southeast of Corpo Sul (see Figure 2) and Chapada on targets that have
already been identified with the goal of unlocking further value at
Chapada. Exploration success to date has ensured a sustainable annual
production level of 150,000 ounces of gold and 135 million pounds of
copper beginning in 2014. Continued exploration success is expected to
extend this sustainable production level for a longer mine life.
