Yamana Update on Chapada and Q4 Production

TORONTO, ONTARIO--(CCNMatthews - Jan. 8, 2007) - YAMANA GOLD INC. (TSX:YRI)(AMEX:AUY)(AIM:YAU) is pleased to provide an update on the start up of its Chapada mine and on overall Q4 2006 production levels at its other operations.

Chapada

The start up of operations at Yamana's Chapada mine has made significant advances as expected and the mine is now producing and selling concentrate on a consistent basis. The Company is on course to declare commercial production at Chapada before the end of Q1 2007 having achieved many substantive milestones including the following:

- Mining continues at a rate of 16M tonnes of ore per year.

- The mill is operating at a rate of 2,100 to 2,300 tonnes per hour with mill availability achieving levels of around 80%, up from approximately 50% in December, which is higher than estimated in the feasibility study at this stage in operations.

- Current production of concentrate is at a rate of approximately 600 tonnes per day, with grades in the range of 26% to 31% copper and 25 g/t to 30 g/t gold. These grades are higher than were estimated for this period in the original feasibility study, and production levels equate to an annualized production rate of more than 210,000 tonnes of concentrate.

- Total concentrate produced to the end of 2006 was 11,364 tonnes, including 297 tonnes of in-circuit inventory. This concentrate contains approximately 29,200 ounces of gold and gold equivalents.

- Production of concentrate projected for January is in the range of 18,000 to 18,500 tonnes at a grade of 26% copper and 25 g/t gold. Current concentrate grades vary from 26% to 30% copper and 25 g/t to 30 g/t gold. Contained gold and copper is expected to be 14,900 ounces of gold and 10.6 million pounds of copper.

- To date Yamana has sold an aggregate of 6,454 tonnes of concentrate from its Chapada mine.

- The total sale proceeds equal US$13.1 million representing a significant advancement on the progress toward commercial production.

"We are extremely pleased with the progress of our Chapada mine," said Peter Marrone, President and CEO of Yamana Gold. "We had not expected to realize any revenue until February and the sale of concentrate at Chapada represents a significant milestone in terms of the logistics of this operation. Quality of the concentrate and the operating rate of the plant exceeds the levels we have set for commercial production. Current production levels, which are fast approaching ultimate design levels, have been achieved after only seven weeks from the initial start up and only three weeks after the full time operation of the plant. Additionally, we are very proud of the achievements of the various operating teams at the mine whose combined efforts enabled us to reach the nominal feasibility production rate of the operation in a very short period of time."

Chapada's production for 2007 and 2008 along with the life of mine (LOM) production is expected to be as follows.



2007 2008 5 Years LOM

Copper 130-145M lbs 165-175M lbs 690M lbs 2B lbs
Gold 180-205,000 oz 170-190,000 oz 700,000 oz 1.4M oz


Once commercial production is achieved, the Company plans to increase gold and copper production at Chapada in part by optimizing the grinding circuit to further improve throughput and by processing 6M tonnes of oxide gold material which can be processed through conventional heap leaching. The Company also continues to assess the feasibility of production of a pyrite concentrate for production of sulfuric acid which would add to revenue from copper-gold concentrate.

Q4 Production

The following compares Q4 production to Q3 production on a mine by mine basis.



-----------------------------------
4th Quarter 3rd Quarter
---------------------------------------------------------------------------
Sao Francisco 37,000 ounces (i)29,658 ounces
---------------------------------------------------------------------------
Jacobina 20,900 ounces 19,321 ounces
---------------------------------------------------------------------------
Fazenda Brasileiro 20,400 ounces 18,569 ounces
---------------------------------------------------------------------------
San Andres 18,300 ounces 15,685 ounces
---------------------------------------------------------------------------
Fazenda Nova 7,900 ounces 6,548 ounces
---------------------------------------------------------------------------

---------------------------------------------------------------------------
Total 104,500 ounces 88,781 ounces
---------------------------------------------------------------------------

(i) Of this amount, 20,789 ounces was commercial production.


Total production is in line with previous guidance for Q4 and represents an increase over third quarter production of approximately 17 per cent. The total gold and gold equivalents including Chapada in Q4 2006 was 133,700 ounces of gold representing an increase over Q3 2006 of approximately 51 percent.

An update to production and cash costs guidance for 2007 and 2008 will be provided in a subsequent company release expected during the second week of January.
