    TORONTO, June 19 /CNW/ - YAMANA GOLD INC. (TSX:YRI)(NYSE:  AUY)(LSE:YAU)
today announced an exploration update for Gualcamayo, El Penon, Pilar de Goias
and Mercedes.

    GUALCAMAYO, ARGENTINA

    Drilling at Gualcamayo continued during the quarter with two underground
and two surface diamond drills. The significant results show:

    
    -   Potential for expanded size of QDD Lower West deposit
    -   Improved grades compared to the original resource model
    -   Added tonnage through increased width of the deposit
    

    In May 2008, results were reported for hole 08QD-516 (110.8 metres of
2.24 g/t Au), which significantly extended the QDD Lower West deposit 175
metres along strike to the northwest. Hole 08QD-515, drilled within this
extension, intersected 34.6 metres of 1.35 g/t Au confirming that QDD Lower
West is open down dip below 08QD-516. Holes 08QD-520, 08QD-522 and 08QD-523
have confirmed or increased the previously known grades of mineralization and,
more importantly, they have significantly increased the thickness of the
deposit thereby adding tonnes. Hole 08QD-523 drilled to the west of the QDD
Lower West deposit extended the known grade shell to the west.

    
    Hole                           From (m)   To (m)  Interval (m)   Au (g/t)
    --------                       --------   ------  ------------   --------
    08QD-518                          9.61    21.45         11.84       1.39
                                     42.67    65.20         22.53       1.21
    08QD-519                         27.36    42.25         15.09       1.06
    08QD-520                           0.0    103.3         103.3       2.40
    08QD-522                          14.2    96.05          81.9       3.87
    08QD-523                          92.4    340.6         248.2       3.00
    including                        116.4    276.7         160.3       4.21
    

    These results continue to support the view that QDD Lower West may be a
larger deposit than is reflected in the current resource estimate. QDD Lower
West is the third and most prospective of the mineralized zones at Gualcamayo.
An update to the feasibility study for QDD and AIM is planned to include QDD
Lower West by year-end. Production is expected to begin at the QDD deposit at
Gualcamayo at the end of 2008 followed by AIM and then QDD Lower West. Total
production at Gualcamayo is expected to exceed 300,000 ounces of gold per year
once QDD Lower West is in production, which is planned for 2010. Planned
production at this level is expected for at least a ten year period.

    EL PENON, CHILE

    In May 2008, Yamana reported the discovery of the Bonanza North extension
with discovery hole SNF0005 which returned 2.75 metres of 78.33 g/t Au and
217.67 g/t Ag. Since that time, an additional 14 drill holes have been
completed at Bonanza North, and the grade shell continues to expand,
supporting the view that the deposit could be at least two times the current
resource estimate.
    Mineralization has now been traced along a strike length for 540 metres
from section 7,860N to 8,400N. Hole EB0009 on section 8,400N intersected 0.48
metres at 17.3 g/t Au and 54.1 g/t Ag, potentially extending the
mineralization an additional 300 metres to the north for a combined strike
length of almost 600 metres. Hole EB0013 was drilled 60 metres north of the
northern end of the Bonanza deposit and returned 2.08 metres of 33.07 g/t Au
and 163.73 g/t Ag, indicating that Bonanza is open to the north.
    Drilling going forward will focus on connecting the Bonanza North deposit
to the Bonanza vein to the south. Should a connection be established the
potential strike length of Bonanza North could be as long as 1,200 metres
while remaining open to the north.

    
    Hole           Section  From (m)  To (m) Interval (m)  Au (g/t)  Ag (g/t)
    ------         -------  --------  ------ ------------  --------  --------
    EB0003           7,920      520     521         0.59     35.50      17.1
    EB0004           7,920      482     483         0.61      9.10      10.7
    EB0005           7,860      478     479         0.54     10.90      41.7
    EB0007           7,860      513     516         1.49      8.77       9.6
    EB0009           8,400      528     529         0.48     17.30      54.1
    EB0013           7,320      328   3,311         2.08     33.07     163.7
    

    Yamana believes these results support its view that El Penon will be able
to achieve an increased sustainable annual rate of production of 500,000 gold
equivalent ounces (GEO) per year by the end of 2008. A detailed mine plan is
in progress to potentially further increase production to approximately
600,000 GEO per year.

    PILAR DE GOIAS, BRAZIL

    Drilling continues at Pilar de Goias where a resource estimate was
provided earlier this year showing inferred resources of 972,000 ounces of
gold at an average grade of 2.42 g/t. Currently, four drills are active.
Results to date have confirmed the reported widths of mineralization and have
locally increased estimated grades.
    The current focus of exploration is concentrated on the completion of an
infill drill program on the JOT trend (Jordino, Ogo and Tres Buracas deposits)
to facilitate the completion of a scoping study by the end of 2008. Three
drill rigs are currently on site. The continuity of the mineralization towards
the south is also being investigated with one drill rig. Infill drilling is
being conducted on a 100 x 100 metre grid. Within this area two smaller blocks
have already been drilled on a 50 x 50 metre grid, to investigate short range
grade variation. Results to date have confirmed the previously estimated
widths of mineralization and have locally increased grades. The results of the
drill program are attached in Table 1.
    Of particular importance is the extension of the JOT trend to the south
of Jordino. The extension is covered by younger rocks of the Araxa sequence
which were thrust over the Pilar greenstone sequence during the
Neoproterozoic. The intersection of 11 metres of 3.87 g/t Au in hole JD008 has
successfully traced the extension of Jordino below the Araxa sequence for at
least 200 metres. Further drilling has been completed for an additional 800
metres to the south, with results pending. With the extension of the Jordino
trend to the south, mineralization has now been traced by drilling along a
strike length of 7 kilometres.
    Pilar de Goias is one of Yamana's most interesting and prospective areas
for exploration with significant potential for one or more discoveries which
would further increase Yamana's targeted production levels.

    MERCEDES, MEXICO

    Drilling continued at Mercedes in the second quarter, with 5 core rigs
currently on-site. Exploration focused on 1) Infill drilling and step-out
drilling on the Mercedes Vein, 2) Infill drilling on the Klondike Vein and 3)
Generative drilling of targets in the Mercedes Northwest Extension, Klondike
Basin and Tucabe Vein systems.
    Since the March 25, 2008 press release, a total of 148 core holes
totaling 37,225 metres have been completed, bringing the total project
drilling to 120,321 metres in 523 holes. Assay results have been received up
to Mercedes hole M08-325.

    Mercedes Vein Zone Results

    Infill drilling and step-out drilling on 30 to 60 metre centres has
successfully identified more than 2.0 g/t of gold equivalent mineralization
(at a 150:1 Ag:Au conversion factor, which reflects relative metal prices and
recovery rates) along a 1,200 metre strike length of the Mercedes Vein.
Gold-silver mineralization is contained within complex multi-stage epithermal
low sulphidation quartz-carbonate vein, stockwork and breccia zones up to 15.0
metres in true width, hosted within a thick sequence of andesite flows and
breccias. Ore grade mineralization occurs over a vertical range of 460 metres
(700 to 1,160 metre elevation).
    Drilling focused on the main Corona de Oro zone as well as several ore
shoots to the southeast (Tierra de Nadie, Centinela and Casa Blanca) and the
newly defined Breccia Hill ore shoot to the northwest.
    The presence of wide and high grade zones of gold and silver
mineralization within the Corona de Oro ore shoot has been further confirmed
by infill drilling on 30 metre centres, highlighted by the following
intercepts:

    
    -   M08-213 17.89 metres (10.50 true width) @ 11.49 g/t Au and
        89.9 g/t Ag
    -   M08-228 11.59 metres (7.00 true width) @ 82.96 g/t Au and
        231.9 g/t Ag

    One deep hole tested continuity of mineralization in the Deep Corona
extension zone at the 760 metre elevation, with the following positive
results:

    -   M08-281 4.53 metres (2.00 true width) @ 27.73 g/t Au and
        106.9 g/t Ag

    Infill and step-out drilling to the southeast of Corona de Oro confirmed
the presence of contiguous ore grade mineralization within the Tierra de
Nadie, Centinela and Casa Blanca ore shoots, including the following drill
intercepts:

    Tierra de Nadie

    -   M08-230 8.99 metres (8.10 true width) @ 24.11 g/t Au and
        156.2 g/t Ag

    -   M08-269 3.33 metres (2.80 true width) @ 12.74 g/t Au and
        132.5 g/t Ag

    Centinela

    -   M08-239 2.98 metres (2.10 true width) @ 24.58 g/t Au and
        130.0 g/t Ag

    -   M08-257 4.70 metres (4.06 true width) @ 27.46 g/t Au and
        75.6 g/t Ag

    -   M08-275 3.60 metres (3.25 true width) @ 29.56 g/t Au and
        168.1 g/t Ag

    Casa Blanca

    -   M08-264 2.58 metres (2.30 true width) @ 6.98 g/t Au and
        279.0 g/t Ag

    -   M08-295 2.62 metres (2.20 true width) @ 9.55 g/t Au and
        90.9 g/t Ag
    

    A new ore shoot was also defined on the Mercedes Vein to the northwest of
Corona de Oro. A contiguous vein containing more than 2 g/t equivalent gold
ranging from 1.0 to 8.0 metres in true width has been identified in 13 drill
holes. The ore shoot extends along strike for up to 150 metres, with a
vertical range of 350 metres. At depth, the zone merges with the northwest
extension of the Corona de Oro shoot. Significant results from the Breccia
Hill ore shoot include:

    
    -   M08-294 9.65 metres (7.20 true width) @ 4.55 g/t Au and
        68.8 g/t Ag
    -   M08-305 9.14 metres (4.95 true width) @ 6.22 g/t Au and
        30.8 g/t Ag
    -   M08-305 3.04 metres (1.64 true width) @ 19.43 g/t Au and
        11.6 g/t Ag
    

    Complete Mercedes infill drill results are shown in the attached Figure 1
and in Table 2.
    With these new results, including the definition of the new Breccia Hill
ore shoot, Yamana believes it is on track to deliver a resource of one million
ounces of gold at Mercedes by the end of 2008. As the company continues with
an aggressive infill program, a significant part of the resource will be in
the Measured and Indicated categories.
    Yamana's continued plan for Mercedes remains on track to deliver a
feasibility level study by the end of the year with the objective to
demonstrate sufficient mineable reserves for an initial mine plan. Drilling
will continue at Mercedes in 2009 and beyond in an effort to outline new vein
zones and extend those that are already known. This is the same approach taken
at El Penon which has continually added new resources through a continued
exploration effort.

    Quality Assurance and Control

    A description of the quality assurance program and quality control
measures applied during the execution of the work being reported on for each
of the Gualcamayo and El Penon projects can be found in the following reports
filed on SEDAR at www.sedar.com: 1) the "Technical Report on the El Penon
Mine, Chile Resource Audit" effective as of October 2007, dated February 11,
2008, (2) the "Mineral Resource Update Gualcamayo Gold Project, San Juan
Province, Argentina" dated March 2008.
    At Mercedes, all samples were collected through diamond drilling, which
is being conducted by Major Drilling. The samples are collected by splitting
the core in half using hydraulic splitters. The average sample size is
approximately 0.9 metres and weighs approximately 2.9 kilograms and the second
half of the core is maintained in secure locked warehouses. The Mercedes
project uses ALS Chemex in Mexico for sample preparation and ALS Chemex in
Vancouver for sample analysis.
    The core samples are picked up directly at the project site by ALS Chemex
and sent to the Chemex prep facility in Hermosillo, Mexico. The total sample
is crushed to +75% passing a 2 mm screen. A smaller portion, up to 250 grams,
is then pulverized so + 85% passes a -200 mesh. The pulps are sent to the
Vancouver laboratory where both Au and Ag are analyzed by fire
assay/gravimetric finish (50-gram pulp). Some samples are also assayed by
metallic screen methods when visible gold is noted, to verify fire assay gold
grades.
    Yamana operates a QA/QC program at Mercedes that includes the insertion
of a series of professionally prepared certified standards and blanks, as well
as locally prepared sterile samples, into the sample stream. A number of
reject samples are systematically forwarded to ACME Laboratory in Vancouver,
for comparison of Au and Ag grades.
