Amerigo Announces Filing of NI 43-101 Technical Report


April 24, 2014 - VANCOUVER, BRITISH COLUMBIA

Amerigo Resources Ltd. (TSX: ARG) ("Amerigo" or the "Company") is pleased to announce that it has made the regulatory filing of the National Instrument 43-101 ("NI 43-101") technical report (the "Report") prepared for Minera Valle Central, S.A. ("MVC"), Amerigo's Chilean subsidiary. The Report has been filed in conjunction with the announcement by Amerigo of the agreement entered into by MVC with Codelco's El Teniente Division ("DET") for the acquisition of the processing rights to the Cauquenes tailings deposit and the extension of MVC's rights to process tailings from the El Teniente mine from 2021 to 2037.

Robert D. Henderson, P. Eng, President and COO of Amerigo is the author of the Report, is responsible for the technical comments related to the resource estimate and its parameters and is a "qualified person" for the purposes of NI 43-101 Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators. Mr. Henderson has verified the data disclosed in this release.

MVC's plant is located approximately 90 kilometres south of Santiago, Chile and has been in operation since 1992. MVC processes tailings from the current production of the El Teniente mine ("Fresh Tailings") and tailings from the historic Colihues tailings deposit. El Teniente is the world's largest underground copper mine and has been in production since 1904. Construction of a new mine level, scheduled for completion in 2017, is estimated to extend the mine's useful life by 50 years.

In 2013, MVC produced 45.7 million pounds of copper and 809,057 pounds of molybdenum. An expansion project (the "Project") is planned to develop the historic Cauquenes deposit that is expected to double MVC's copper production to approximately 90 million pounds per year.

The Colihues and Cauquenes tailings deposits are located in close proximity to MVC's plant. The MVC plant has a capacity of 175,000 tonnes per day and consists of grinding and flotation processing facilities. After being reprocessed at MVC, the tailings are transported by gravity to the Caren tailings impoundment, located approximately 50 km to the west of the MVC plant.

MVC currently mines the Colihues deposit with hydraulic monitors and plans to mine the Cauquenes deposit using the same method. The Project will require construction of additional mining infrastructure, grinding and flotation plants.

In Mr. Henderson's opinion there is sufficient geological and economic evidence to conclude that MVC's contracts for the processing of Fresh Tailings and tailings from the Cauquenes and Colihues tailings deposits constitute an inferred mineral resource. Historical records of El Teniente's mill tailings represent a detailed account of the tonnage and grade of material stored in the Cauquenes and Colihues impoundments. A total of 30 holes have been drilled on the Cauquenes deposit in four separate campaigns. MVC has a long operating record of economic extraction of copper and molybdenum from Fresh and Colihues tailings, and MVC's 2014 feasibility study demonstrates that tailings can be profitably extracted from the Cauquenes deposit.

MVC's total inferred mineral resource estimate for the Fresh, Colihues and Cauquenes tailings, after application of mining and mill recovery losses, is 1,494 million tonnes at a grade of 0.155% Cu and 0.012% Mo with 1,709 million pounds of recoverable copper and 43 million pounds of recoverable molybdenum, as set out in the following tables:

The Cauquenes Expansion Project Environmental Impact Assessment study was filed with the Chilean authorities on January 7, 2013, requesting an increase in the historic tailings processing rate via an expansion of the MVC plant. Environmental approval is expected to be received in the first half of 2014. The January 2014 Cauquenes Expansion Project Feasibility Study development plan anticipates construction to commence in the second half of 2014. The Study calls for a Cauquenes processing rate of 60,000 tonnes per day and a phased start up estimated to commence in Q2-2015, with full production expected to be achieved in Q2-2016. Processing of the Colihues deposit is planned to be phased out and restarted in 2034 when the Cauquenes deposit is depleted.

Average annual production over the initial ten year period (2016-2025) is estimated to be 88 million pounds of copper per year at a cash cost of production of approximately $1.51/lb Cu, excluding royalties. Royalty payments are estimated to be $0.69/lb Cu at the base case metal prices used in the economic analysis. The initial capital cost of the Project has been estimated at $140 million, including contingency and excluding escalation. At an 8% discount rate, the unlevered after tax net present value for the Project is estimated to be approximately US$279 million at an assumed long term copper price of $2.95/lb Cu, rising to US$441 million at a price of $3.50/lb Cu. Over the life of the contract, assuming a copper price of $3.50/lb, total EBITDA for MVC is estimated to be $3.1 billion, of which $1.6 billion is payable to DET as royalties.

Using these parameters, the preliminary financial analysis of the Project indicates that MVC has a positive net cash flow and an acceptable internal rate of return and supports progression to construction and development of the Cauquenes deposit.

The results of the preliminary economic assessment represent forward-looking information that is subject to a number of known and unknown risks, uncertainties and other factors that may cause actual results to differ materially from those anticipated in such information. This information speaks only as of the date of this Technical Report, and is based on a number of assumptions which are believed to be true but which may prove to be incorrect in future. The preliminary economic assessment is preliminary in nature and it includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the preliminary economic assessment will be realized

In Mr. Henderson's opinion the data supporting the inferred mineral resource estimates were appropriately collected, evaluated and estimated, and the Project objective of identifying tailings mineralization that could potentially support future processing operations has been achieved. Mr. Henderson's recommendation is to proceed with construction of the Project.

Amerigo Resources Ltd. produces copper and molybdenum under a long term partnership with the world's largest copper producer, Codelco, by means of processing fresh and old tailings from the world's largest underground copper mine, El Teniente near Santiago, Chile.
