VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 24, 2012) - NETCO SILVER INC. (TSX VENTURE:NEI) ("Netco") and MARIFIL MINES LTD. (News - Market indicators) ("Marifil") are pleased to announce that they have entered into an assignment and purchase agreement dated September 19, 2012 (the "Purchase Agreement") whereby Netco has agreed to purchase all of Marifil's 100% interest in the Toruel copper-silver project (the "Toruel Property"), located in the Rio Negro Province of Argentina, and all exploration data related thereto (the "Transaction"). Netco and Marifil believe that the Transaction is in the best interests of their respective shareholders as owning a 100% interest in the Toruel Property will facilitate Netco's ability to finance work programs at the Toruel Property and the ownership interest that Marifil will acquire in Netco, as described below, will enable Marifil's shareholders to benefit from the exploration and development of the Toruel Property by Netco.

Netco and Marifil are currently parties to an option agreement dated March 3, 2011, as amended (the "Option Agreement"), pursuant to which Marifil granted Netco an option to acquire up to a 70% interest in the Toruel Property. Under the terms of the Purchase Agreement, Marifil will assign and sell to Netco all of its interest in the Toruel Property in consideration for:

1. Netco issuing Marifil an aggregate of 3,500,000 share purchase warrants (each, a "Warrant"), with each Warrant entitling Marifil to acquire one common share of Netco (each, a "Share") at a price of $0.10 per Share until the date that is twelve (12) months from the closing of the Transaction (the "Closing") and at a price of $0.15 per Share from the date that is twelve (12) months from the Closing until the date that is twenty-four months from the Closing;
   
   
2. Netco issuing to Marifil such number of Shares as will cause Marifil to hold an aggregate of 19.9% of the issued and outstanding Shares at Closing; and
   
   
3. the grant of a 3% net smelter returns royalty to Marifil.
   
   

Netco has also agreed to assume Marifil's existing property payment obligations to the underlying owners of the Toruel Property upon Closing.

The Transaction is expected to close on or about November 30, 2012. The Closing of the Transaction is subject to a number of conditions, including:

1. the approval of the TSX Venture Exchange and of the underlying owners of the Toruel Property, if applicable;
   
   
2. Netco having funds in the minimum amount of $825,000 (the "Closing Funds"), of which $375,000 shall be used to complete the purchase of claims from an underlying owner of the Toruel Property and $450,000 shall be used for a drill program on the Toruel Property;
   
   
3. satisfactory completion of all transactions contemplated in the Purchase Agreement; and
   
   
4. Marifil and Netco having executed a termination and release confirming the termination of the Option Agreement.
   
   

In the event that Netco is unable to provide evidence to Marifil of holding the Closing Funds at the time of the Closing, the Purchase Agreement and the Option Agreement shall be terminated.
