Amerigo Announces Record Q1 2011 Production Results

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 05/05/11 -- Amerigo Resources Ltd. (TSX: ARG) ('Amerigo' or the 'Company') is pleased to announce production results for the first quarter of 2011 from Minera Valle Central ('MVC'), the Company's operations located near Rancagua, Chile. MVC produced 11.14 million pounds of copper and 212,125 pounds of molybdenum during the three months ended March 31, 2011.

Amerigo's President and CEO, Dr. Klaus Zeitler, stated: 'MVC's production in Q1-2011 of both copper and molybdenum were the highest of any first quarter in the Company's history. Copper and molybdenum production for the quarter were 30% and 20% higher, respectively, than previous first quarter production records. Management is confident that these excellent results put the Company well on its way to meeting projected production for both metals in 2011. We congratulate all of our team for their excellent work.'

Dr. Zeitler continued, 'Power costs remain at high levels due to Chile's ongoing drought, but MVC's long term contract with its energy supplier provides for a price ceiling that is lower than current marginal energy costs until 2013 when our power contract provides for a fixed price that is less than one-half of our present power costs. MVC's generating plant also contributes to the containment of power costs. In addition, MVC is in the process of obtaining additional water rights which will allow it to continue to maximize production despite the effects of the drought.'

Key operating and sales metrics are shown below.

(1) Copper sales per the Company's records, which may differ from copper
sales per the smelter. All differences between Company and smelter records
for a quarter will be recorded as settlement adjustments in subsequent
quarters until settled.
(2) Copper price recorded for the Company's financial statements for the
quarter before smelter and refinery charges and settlement adjustments to
prior periods' sales and after hedging. The Company calculates this number
by dividing quarterly dollar sales as recorded in its financial statements
(calculated based on copper deliveries per the smelter) over quarterly
copper sales per the Company's own records.
(3) Calculated from dividing the dollar value of gross copper quarterly
sales over copper sales per the Company's records. If the calculation was
done using copper sales per the smelter, the normalized recorded copper
price would be $3.12/lb.

Among the factors that have a direct bearing on the Company's future results of operations and financial conditions are changes in project parameters as plans continue to be refined, interruptions in the supply of fresh tailings from El Teniente, further delays in the extraction of tailings from the Colihues tailings impoundment, a change in government policies, competition, currency fluctuations and restrictions and technological changes, among other things. Should one or more of any of the aforementioned risks and uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from any conclusions, forecasts or projections described in the Forward-Looking Information.
