Vancouver, B.C. -- Dec 14, 2011, MARIFIL MINES LTD. (MFM: TSX-V) ("Marifil" or "the Company") announces that Netco Silver Inc. ("Netco") has provided an update on exploration work at the Company's Toruel Project, Rio Negro Province, Argentina.

The current program consists of soil sampling, rock sampling, prospecting, trenching and geological mapping. The objective of the program is to identify additional vein systems and establish priority locations for a subsequent drill program, with the immediate goal of outlining a high grade zone amenable to direct shipping of high grade ore.

To date the program has identified three (3) new vein structures:

 

• Approximately 500 meters east of the Saba Vein, strike 45°: This new vein shows the potential to be the continuation of the Toruel East vein system. Approximately 1000 meters in length, it is comprised of strong massive quartz stock work, druzy quartz, and fluorite. The host rock is crystal rhyolite tuff.

   

• Approximately 200 meters West of Saba Vein, strike 120°: About 200 meters in length this vein is steep/vertical and comprised of strong quartz stock work and massive quartz. The host rock is crystal rhyolite tuff, locally brecciated by the vein. This vein could represent a later system than the Saba and Toruel veins, and cut the NE trending veins.

   

• The third vein system is parallel to the Ancha vein and located about 600 meters South West of the Canyon vein. This is likely the same system as the Ancha vein. It has strong stock work of druzy quartz and massive quartz in small bands. The host rock is rhyolitic tuff.

A total of 169 rock chip samples have been collected at the Toruel Project. Samples have been submitted to Acme Analytical Laboratories in Mendoza for two assay methods; Gold Fire-Assay 50gm fire-assay fusion and an Exploration Elements Package that consists of a 4 acid digestion with ICP-MS detection. Results are expected around mid-January 2012. A program of trenching and further sampling will commence in January 2012.

The Toruel Property, covering 5,736 Hectares, is located about 25 kilometers southeast of the village of Los Menucos, Rio Negro Province, Argentina, and is prospective for silver, gold, indium, copper, lead, and zinc. The Company has granted Netco the option to acquire up to 75% of the property.
