TORONTO, ONTARIO--(Marketwire - Sept. 12, 2007) - Anaconda Mining Inc. (TSX:ANX)(FRANKFURT:GJ2) is pleased to announce that it has signed a Definitive Exploration Earn-in Agreement ("Agreement") with Minera Penoles de Chile, a wholly owned subsidiary of Industrias Penoles, S.A.B. de C.V. ("Penoles") to jointly explore and develop Anaconda's Carmen copper-gold project in the Inca de Oro District, Chile.

Anaconda and Penoles agreed earlier to expand the property holdings in the Carmen project area by acquiring additional concessions from a third party, Inversiones EM DOS Limitada, ("EM DOS"), a private Chilean company. This increases the size of the Carmen mining concessions from 822 hectares to 1,271 hectares. (See Anaconda press release dated June 7, 2007 at


Under the terms of the Agreement, Penoles has the right to earn a 65% interest over a 48-month period by spending a total of US$22 million. Of this amount, US$12 million will comprise cash payments to Anaconda and EM DOS and US$10 million will comprise direct exploration expenditures on the project.

Penoles will make the initial US$3 million cash payment on September 27 of which US$2,050,000 will be paid to Anaconda and US$950,000 will be paid to EM DOS. As well, in the first year of the Agreement, Penoles is required to spend US$3 million on exploration including but not limited to 12,000 metres of drilling.

During the second 12-month period, Penoles will pay Anaconda US$1,950,000 and EM DOS US$1,050,000 and will spend US$3 million on exploration including but not limited to 15,000 metres of drilling.

During the third 12-month period, Penoles will pay Anaconda US$1,800,000 and EM DOS US$1,200,000 and spend US$4 million on exploration.

At the end of the 48-month exploration period, Penoles will make a final minimum payment of US$900,000 and a maximum of US$3 million. If Penoles spends in excess of US$4 million during the third 12-month period, that excess expenditure will be deducted from the US$3 million maximum payment but in any event, a minimum US$900,000 payment will be made. In the event that Penoles makes the minimum payment, that payment will be to the benefit of EM DOS. Any payments in excess of US$900,000 and up to the maximum of US$3 million will be made to Anaconda.

In the event that Penoles earns its 65% interest in the Carmen project, Anaconda will hold a 24.5% interest and EM DOS will retain a 10.5% interest.

As part of the transactions, Anaconda has also granted Penoles a limited option to sell to or acquire from Anaconda their respective interests in the Carmen project at fair value only after Penoles has earned its full interest and only in the event of certain material change of control events within the Anaconda group of companies.

Bankable Feasibility Study

If Penoles elects to finance the preparation of a bankable feasibility study, then Penoles will increase its project interest to 70% with Anaconda and EM DOS reducing their interests to 21% and 9% respectively.
