Amerigo Resources Ltd. – MVC Production

VANCOUVER, BRITISH COLUMBIA – April 20/CNW/Amerigo Resources Ltd. (TSX:ARG) (“Amerigo” or the “Company”) announced today that El Teniente has diverted the fresh tailings normally received by the Company’s plant due to environmental concerns in connection with a construction incident at El Teniente’s tailings operations. Although the Company has not yet received official confirmation from El Teniente, we understand that El Teniente expects the problem to be resolved in approximately 2 weeks.

As a consequence it has been necessary for the Company to shut down its plant until the tailings flow is restored. Management estimates that the Company will experience a production shortfall in April of approximately 700 tonnes of copper and 40,000 pounds of molybdenum as a result.

The Company is taking advantage of the situation by accelerating maintenance previously scheduled for later periods and redeploying labour accordingly. The Company is also investigating the possibility of compensation from its business interruption insurance.

In the 14 year operating history of the plant there has never been a tailings disruption of this nature, and El Teniente has not indicated that a recurrence is likely.

Amerigo is a Canadian copper and molybdenum producing company with operations near Santiago, Chile. Tel.: (604) 681-2802; Fax: (604) 682-2802; Web:; listing: ARG:TSX.
