Marifil Signs Agreement for Its Toruel Silver Property

MARIFIL MINES LTD. (TSX VENTURE:MFM) ("Marifil" or "the Company") announces that
it has entered into an agreement with Netco Energy Inc. ("NEI") whereby NEI can
earn up to a 75% interest in Marifil's Toruel property (the "Property").


Under the terms of the agreement, NEI can earn a 50% interest during the next
three years by paying an aggregate of $200,000 in cash, issuing 3,150,000 NEI
common shares to Marifil and making work expenditures of $2,800,000 on the
Property. NEI can earn a further 10% over the next two years by providing
Marifil with a pre-feasibility study on the Property and paying the Company
$100,000 per year. NEI can earn a further 10% over the next two years by
providing Marifil with a feasibility study on the Property. At that time, all
further expenditures shall be shared, with 70% covered by NEI and 30% by
Marifil. However, at Marifil's sole option, the Company can elect to be carried
through to the commencement of commercial production on the Property, in which
case NEI will earn an additional 5% interest, bringing its interest to 75%.


In the event NEI fails to provide the Company with a feasibility study in the
allotted time then, at Marifil's option, NEI's interest may be reduced to 49%.


The Property is located about 25 kilometers southeast of the village of Los
Menucos, Rio Negro Province, Argentina. The targets on the Property are
epithermal veins and vein breccias containing high grade silver and copper
values along with important amounts of gold and indium. More than 20 veins have
been identified within a structural corridor 4 to 5 kilometers wide and more
than 7.8 kilometers long. Many large veins remain untested.


Marifil has completed 5,890 meters of drilling, most of it along the Toruel
vein. The main Toruel vein has been traced for 1,900 meters along strike with
widths up to 15 meters. Drill hole DDH-32 cut 6.7 m (true width 4.0 m), grading
1,900 g/t silver and 5.3% copper.


Mr. John Hite reports, "This is now the sixth transaction completed by Marifil
in the last nine months. Four of these are joint ventures and two are outright
sales. In total we expect to take in more than $1 million in cash and more than
$1 million in marketable securities in 2011. Over the next few years our
partners will be spending almost $20 million in direct property costs and will
also, in several cases, be providing us with pre-feasibility and feasibility
reports. Our strategy of farming out our properties while retaining significant
carried, or working interests and/or royalties is working and should result in
gains for our investors."


This press release has been reviewed and approved by John Hite, President of
Marifil Mines Ltd., and by Richard Walters, Vice President, under whose
directions the exploration program is being carried out. Mr. Hite and Mr.
Walters are Qualified Persons as defined by National Instrument 43-101.
