- Fazenda Nova start-up of crushing and agglomeration commences

- Loading of heaps will commence within the next week

- First gold pour expected in the Fall

- Total capital expenditures below budget of US$6.6 million

- Total cash costs now targeted at approximately US$160 per ounce (life of mine) from the original
target of US$186 per ounce

- Total production from initial phase at over 143,000 ounces in over four years with annualized

Yamana Gold Inc. (TSX:YRI; AMEX:AUY; LSE (AIM):YAU) announces the start-up of its Fazenda Nova mine.
Crushing and agglomeration began June 17, 2004. Commissioning is expected in the next few days and
loading of heap leach pads is expected by the end of next week.

The construction of the mine began six months ago and has been completed ahead of schedule despite an
unusually heavy rainy season earlier in the year. The construction cost is below the original capital
expenditure estimate of US$6.6 million.

Production of gold at Fazenda Nova will begin in the Fall (accounting for the leaching process) and
expected annual production will average approximately 36,000 ounces per year for a total of 143,000
ounces in the initial phase of its mine life of over four years.

Total cash costs estimates have been reduced to approximately US$160 per ounce (life of mine) from the
original estimate of US$186 per ounce. The largest component of costs relates to agglomeration and
favourable current terms with cement manufacturers together with other improvements have reduced
estimated cash costs to this new level. Cash costs will vary period to period and will begin at higher
levels in the start-up of operations and will vary with changing cement contract terms throughout the
life of mine. Total cash costs include royalties and taxes.

The Fazenda Nova mine is located in Goias State, Brazil almost 200 km from the state capital of
Goiania and 300 km from the national capital of Brasilia. Infrastructure around the site is
exceptional with several towns in close proximity. The site is readily accessible by paved roads and
power will be provided by an existing transmission grid. The mine is a shallow open-pit heap leach
mine with three initial pits to a depth of 50 to 60 metres in saprolite ore.

The recovery rate is estimated at 88% based on a 90 day leaching cycle. The recovery rate is based on
significantly higher recovery rates over shorter leach cycles in laboratory tests (95% recovery over
15 days) and comparable experience at other deposits of saprolite ore.

Yamana now has two mines in production (Fazenda Brasileiro at an annual rate of over 100,000 ounces
per year and Fazenda Nova at an annual rate of over 36,000 ounces per year) and expects to produce
approximately 110,000 ounces in calendar 2004 (accounting for the leaching process at Fazenda Nova) or
over 135,000 ounces on an annualized basis at an average total cash cost per year between the two
mines of approximately US$210 per ounce.

Commenting on this development, Yamana's President and Chief Executive Officer Peter Marrone stated,
"We have committed ourselves to a high quality process for development of our projects. We have are
pleased to have reached this stage with the Fazenda Nova mine. Our total annualized production
commencing this year will be some 135,000 ounces from our two mines at approximately US$210 per ounce
cash costs. We are on track towards our stated objective of becoming an intermediate producer in the
next two years. We will continue to maximize our production and development opportunities and we have
now also started an aggressive drilling and exploration campaign to increase reserves, extend mine
life and find new deposits."

Yamana is a Canadian gold producer with significant gold production, gold and copper-gold development
stage properties, exploration properties and land positions in all major mineral areas in Brazil.
Yamana expects to produce gold at intermediate company production levels by 2006 in addition to
significant copper production by 2007. Yamana also holds gold exploration properties in Argentina.
Company management plans to build on this base by targeting other gold consolidation opportunities in
Brazil and elsewhere in Latin America.
