Marifil Mines Ltd.: Drilling Update on Cerro Samenta Porphyry Copper

MARIFIL MINES LTD. (TSX VENTURE:MFM) ("Marifil" or "the Company") reports
drilling began on February 3rd on its Cerro Samenta porphyry copper project in
Salta Province, Argentina. The Company's joint venture partner, Southern Copper
Corp. (SCCO), plans to drill six holes totalling about 3,000 meters. 


DDH-1-S-14 was drilled at an angle of -45 degrees to a depth of 500 meters.
Persistent supergene copper mineralization is observed in the core throughout
the first 125 meters. This mineralization includes neoticite (a manganese copper
oxide), malachite, and chrysocolla (the latter two are oxide copper minerals). A
second interval from 220 and 260 meters shows stronger oxide copper
mineralization. 


DDH-2-S-14 is located about 350 meters southeast of DDH1 and was in progress
when a Company representative was present. 


A third drill site has been set in the valley to the east of and well below the
elevation of the first two holes in order to achieve a deeper penetration of the
observed copper mineralization.


The HQ & NQ size drill cores are being sawed lengthwise into two meter samples
to be sent to the SGS preparatory station in Mendoza, and from there to an SGS
assay laboratory in Lima, Peru. 


Marifil reported channel sampling copper assay results of ten trenches located
in the vicinity of DDHs 1 & 2 prior to venturing the property with SCCO (see the
Company's press release February 29, 2012). The sampling program was carried out
by Petro Gold Services Mineros S.R.L., an independent geological services
company based in Santiago, Chile. Trenches I and M are located 200 to 400 meters
east of a line between DDH 1 and DDH 2. Trench I contains 52 meters of 1.21%
copper, and Trench M exposes 22 meters of 4.19% copper.


Five SCCO geologists are working on the property. In addition to the drilling,
they are accomplishing grid geochemical sampling (so far 1,322 samples),
detailed geological and topographic mapping and surveying, and continuous rock
chip sampling using an excavator for trenching. This work defines a three phase
granodioritic porphyry system with associated volcanics. The two earlier phases
are mineralized with copper; the youngest phase is un-mineralized.


Marifil's Cerro Samenta property is a porphyry Cu-Mo prospect located 270
kilometers west of the city of Salta in the Puna region of northwestern
Argentina. It covers 5,300 hectares located on the transverse continental scale
Archibarca Lineament, which also localizes Escondida situated 120 kilometers to
the northwest of Samenta in Chile, as well as several other porphyry copper
properties in the region including the nearby Taca Taca copper-gold molybdenum
deposit (Lumina Copper Corp.) and also the Rio Grande (Regulus Resources Inc.)
and Lindero/Arizaro (Goldrock Mines Corp.) copper-gold deposits. 


Marifil expects to release more information on this drilling program as it
becomes available. It is projected for completion by late April. Complete drill
cores assay returns should be available in the next few months.
