Molybdenum plant commissioned ahead of schedule - One-off operating events impact bottomline earnings

· Issued by Amerigo Resources Ltd via CNW
VANCOUVER, May 6 /CNW/ - AMERIGO RESOURCES LTD. (Vancouver, British
Columbia) reported results of the three-month period ended March 31, 2005
today. Significant events are as follows:

-  Net earnings after tax for the quarter ended March 31, 2005 were
   US$1,644,722 compared to earnings of $2,578,907 in the immediately
   preceding quarter.

   Earnings were impacted by an annual charge of US$504,760 for
   stock-based compensation, as prescribed under a recently enacted
   accounting standard. This is a non-cash expense to the Company arising
   from the annual stock option grant to employees, officers and
   directors. Net earnings for the quarter ended March 31, 2005 before
   stock-based compensation were $2,149,482, compared to earnings of
   $2,578,907 in the immediately preceding quarter.

   Earnings were also impacted by the following one-off operating events:

   -  9 days downtime due to El Teniente maintenance shutdown in January

   -  Shell failure in Mill no. 4 resulted in reduced grinding capacity
      and lower recoveries for 2 weeks

   -  Flotation cells taken offline to install new aeration equipment as
      part of expansion to optimize future recoveries

   -  Below budget Colihues extraction due to late delivery of new
      extraction equipment

-  Production under budget - Despite the one-off events mentioned above,
   production was down by only 14% compared to the previous quarter and
   11% higher than Q1-2004 production. Copper produced in Q1-2005 was
   7.50 million pounds, compared to 6.78 million pounds of copper
   produced in Q1-2004.

-  Cash costs before El Teniente royalty were higher at US$0.91 per pound
   in Q1 - 2005 compared to US$0.76 in the preceding quarter and US$0.64
   in Q1-2004. Lower production and a high percentage of fixed costs
   result in higher cash cost per pound.

   Cost increases are also due to higher energy and steel costs, and
   significantly higher smelter and refinery charges in 2005 consistent
   with industry-wide increases to treatment, refining and shipping
   charges. Smelter and refinery charges were US$0.35/lb in the quarter,
   compared to an average cost of US$0.20/lb in 2004. Since MVC does not
   ship concentrate overseas, smelter and refinery charges include the
   participation by the smelter in MVC's cost savings for shipping.

   MVC management also took the opportunity offered by the El Teniente
   shutdown to undertake annual maintenance of the MVC plant.
   Accordingly, maintenance costs of US$0.15/lb are 27% above budget.
   Maintenance costs per pound are expected to decrease in subsequent
   quarters as a result of the "upfront" maintenance undertaken in Q1.

   Total costs after royalty, depreciation and accretion were US$1.14 per
   pound in the quarter ended March 31, 2005 compared to US$0.98 in the
   preceding quarter and US$0.80 in Q1-2004. Contributing to the total
   cost increase are higher royalty payments at higher copper prices.

   The outlook for the remainder of the year should see lower operating
   costs per pound due to higher expected production related to the plant
   expansion and the benefit of molybdenum production as a by-product
   credit.

-  Cash balances increased to US$8,812,296 at March 31, 2005 after
   capital expenditures of US$4,517,658 in Q1-2005 related to the copper
   plant expansion and the molybdenum plant.

-  Molybdenum plant completed in the quarter - Construction for the
   molybdenum plant was completed on March 2005, 3 months ahead of
   schedule. Production of saleable molybdenum concentrate started during
   the commissioning phase in April 2005 and is expected to be in excess
   of 500,000 pounds of molybdenum in concentrates in 2005, with an
   increase to 800,000 to 1,000,000 pounds in 2006.
