VANCOUVER, BRITISH COLUMBIA--(Marketwired - July 22, 2013) - Amerigo Resources Ltd. (News - Market indicators) ("Amerigo" or the "Company") announced today that it has received official notice that the board of directors of the Corporacion Nacional del Cobre de Chile ("Codelco") has approved the major terms of an agreement between Codelco's El Teniente Division ("ET") and the Company's Chilean subsidiary, Minera Valle Central, S.A. ("MVC") granting MVC the rights to process the historic tailings in the Cauquenes deposit located near MVC's plant and extending the fresh tailings contract to 2037.

Dr. Klaus Zeitler, Amerigo's President and CEO, stated "This is a major milestone for the Company. It will allow Amerigo to double annual copper and molybdenum production and will extend from 2021 to 2037 MVC's right to process fresh and old tailings from El Teniente. The Company anticipates receiving final environmental and regulatory approval for the project within the next several months, during which time the Company and ET will work together to finalize the details of the formal agreement. The Company is also currently in advanced discussions to obtain project financing."

Rob Henderson, Amerigo's Chief Operating Officer, added "When Cauquenes reaches full production levels in 2015, Amerigo's per pound production costs are estimated to be reduced by more than 20% from current levels, significantly improving the Company's financial results and reducing MVC's dependence on El Teniente's daily production. The feasibility study is in its final stages and MVC is now in a position to place equipment orders for the first phase of the expansion."

Copper production from Cauquenes will be subject to a sliding scale royalty for LME prices from US$1.95 to US$5.50 per pound, with a base rate of 16% that will vary with the copper price. There will be an adjustment mechanism in the formal agreement for prices outside of the LME price range for the Cauquenes royalty. The fresh tailings royalty will also be changed to a sliding scale and modified to remove disadvantageous foreign exchange rate provisions. .The base rate for the fresh tailings royalty will be 13.5%, and the threshold increased from US$0.80 per pound to US$1.95 per pound, the same minimum level as that for the Cauquenes royalty. The minimum price level for paying royalties is based on MVC's operating costs, including depreciation and financing costs, and will be adjusted to MVC's actual costs one year after Cauquenes is in full production. The parties will meet and review the cost and royalty structure if and when MVC's cost structure changes significantly. The formal agreement will also contain provisions allowing Codelco to purchase MVC's operations at certain predetermined times based on their future net present value.

The Company will provide additional details after all environmental approvals are obtained, the feasibility study has been completed, and financing arrangements and the formal agreement have been finalized.

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. Tel: (604) 681-2802; Fax: (604) 682-2802; Web: www.amerigoresources.com; Listing: ARG:TSX
