Marifil Partners With Southern Copper on Cerro Samenta

VANCOUVER, BRITISH COLUMBIA--(Marketwired - May 29, 2013) - MARIFIL MINES LTD. (TSX VENTURE:MFM) ("Marifil" or "the Company") announces that it has signed a definitive agreement with Southern Copper Argentina ("SCA"), a wholly owned subsidiary of Southern Copper Corporation SCCO for SCA to acquire a 70% equity interest in the Company's Cerro Samenta porphyry copper project in Salta Province, Argentina (see Marifil News Release dated Feb. 29, 2012 for details on the Cerro Samenta Property).

The agreement is subject to the following terms to earn a 70% equity interest in the property (all dollar amounts shown are in United States Dollars):

1.  SCA will pay Marifil a total of $375,000 over four years including
    $75,000 on signing the agreement 
2.  SCA will carry out a minimum $4 million work program on the property
    over four years
    SCA will make the contract payments on behalf of Marifil to two
    underlying property owners over a six years period. 

Additionally, SCA can increase their equity interest from 70% to 80% by providing Marifil with a bankable feasibility study within seven years of the date of signing.

Mr. John Hite states, "We welcome Southern Copper as a partner to help us develop this porphyry copper property. The past two years have been particularly difficult for the junior market with the stock prices of almost half of all TSX-V listed companies being under 10 cents per share."

"This agreement also removes the financial burden of the underlying property payments and advances our business model by having other companies finance exploration on our properties."

"We are excited to work with Southern Copper, a major producer who brings development and production experience to Cerro Samenta. Argentina has received some bad press suggesting that it is a poor place to invest. We disagree with this assessment and point out that not only is SC planning to explore and develop projects in Argentina but other major companies such as Chevron, Agrium, Barrick, and Xstrata are also spending billions of dollars on new projects."
