Amerigo Reports Molybdenum Concentrate Production

VANCOUVER, April 26 /CNW/ - AMERIGO RESOURCES LTD. is pleased to report
that it is producing saleable molybdenum concentrate at its Minera Valle
Central S.A. (MVC) plant located near Santiago, Chile. The molybdenum plant
extracts molybdenum from the copper concentrate which MVC has been producing
for several years from the tailings of Codelco's El Teniente mine. MVC's
copper concentrate has traditionally contained approximately 0.8% molybdenum,
but MVC has not previously extracted the molybdenum from the copper
concentrate and could not receive credit for the molybdenum.
Commissioning of the molybdenum plant started in March 2005, 3 months
ahead of schedule. During the commissioning period MVC undertook mechanical,
electrical, instrumental and operational testing of the plant including the
training of operators. After fine-tuning and initial optimizing of reagents,
MVC is now producing molybdenum concentrates with saleable specifications. MVC
expects to ship the first commercial quantity of approximately 25 tonnes of
molybdenum concentrates towards the end of the month, containing approximately
25,000 pounds of molybdenum. The production of this quantity of concentrates
to specification is significantly ahead of internal schedules, and vindicates
the rigorous study and analysis undertaken by MVC management of metallurgy and
process design prior to committing to construction. It is estimated that plant
construction costs will come in at less than US$3.5 million; at current moly
prices it is anticipated that this project will generate an exceptional rate
of return on investment.
During commissioning it has also become apparent that the molybdenum
plant has significant spare capacity allowing MVC to increase molybdenum
production as copper concentrate volumes increase in future without further
expansions.
MVC estimates production in excess of 500,000 pounds of molybdenum in
concentrates in 2005, and expects to increase molybdenum production to
approximately 800,000 to 1,000,000 pounds in 2006.
A sales agreement has been reached with Molybdenos y Metales S.A.
(known as "Molymet"), one of the world's largest molybdenum producers with
a conversion facility only 75 km from the MVC plant. The agreement has an
initial period of 3 years with a base treatment charge of US$0.60 per pound
of molybdenum plus a price participation factor based on the molybdenum price.
Demand for molybdenum, or "moly", is very strong because of demand from
China and global petroleum pipeline construction. Molybdenum is generally
found as a by-product of copper production and is used in steel alloys,
particularly stainless steel. Current prices for molybdenum oxide are
approximately US$35 per pound, as compared to an average price for 2004 of
about US$17 per pound and a five-year average to the end of 2004 of about
US$6.27 per pound.
Production costs are expected to be below US$3 per pound of molybdenum,
with the majority of these costs being for reagents.
MVC will pay Codelco a royalty of 10% of the revenue of MVC that
originates from the sale of molybdenum concentrate. The royalty on net revenue
was negotiated as part of the agreement for increasing extraction from the
Colihues tailings impoundment from 10,000 tonnes of tailings per day to 45,000
tonnes per day, and is set out in an agreement in principle reached between
MVC and El Teniente. El Teniente is preparing a final form of the agreement.
Based on present molybdenum prices, El Teniente would receive
approximately US$3 for each pound of molybdenum in concentrates produced.
Based on the five-year average molybdenum price of US$6.27, the El Teniente
royalty would be approximately US$0.50 per pound.
A royalty is also payable to a company associated with 2 of the Company's
directors, Mr. Steven Dean and Dr. Klaus Zeitler, on all production by MVC.
Based on the agreed formula, this royalty would amount to approximately
US$0.33 per pound of molybdenum produced at present prices, and approximately
US$0.11 per pound, based on the five-year average molybdenum price. This
royalty was negotiated between Amerigo and Mr. Dean and Dr. Zeitler when Dean
and Zeitler assigned the option to acquire MVC to Amerigo in an agreement
completed in March 2003 (the "Assignment Agreement"), and was approved by
shareholders in June 2003. Under that agreement, Dean and Zeitler could either
receive 7,500,000 common shares of the Company, or a royalty on all production
by MVC. Dean and Zeitler subsequently elected in May 2003 to receive the
royalty as consideration for the assignment of the option.
Recently it was brought to the board of directors' attention that the
description of the royalty payable pursuant to the Assignment Agreement was
incomplete, as the method of calculating the royalty paid on metals other than
copper produced by MVC was not addressed. The correct description of the
royalty is: (i) US$0.01 for each pound of copper equivalent produced if the
price of copper is under US$0.80; and (ii) US$0.015 for each pound of copper
equivalent produced if the price of copper is US$0.80 or more. The incomplete
description of the royalty in the Assignment Agreement was a mutual mistake
between the Company and Messrs. Dean and Zeitler. In connection with their
review of this matter, the board of directors received sworn affidavits from
the two former directors of the Company involved in the negotiations at the
time who approved the original Assignment Agreement as well as from Messrs.
Zeitler and Dean confirming that there was an agreement between the parties to
pay the royalty on all production by MVC. Based on these facts and on legal
advice received from the Company's external counsel Gowling Lafleur Henderson
LLP, the board of directors of the Company has determined that the Assignment
Agreement and related disclosure should be rectified to reflect the original
agreement of the parties.

Amerigo Resources Ltd. is a Canadian copper and molybdenum producing
company forecasting 18,000 tonnes of copper production and 500,000 pounds
of molybdenum in 2005 from its MVC operations near Santiago, Chile.
