Mexican Exploration Highlights:

• Hole LP986 drilled to test a Source target area at Rincón del Caído encountered mineralized marble associated with a sub-horizontal structure 185 metres (“m”) above a felsic intrusive body.  The zone assayed 398 g/t (11.6 oz/T) Ag, 3.97% Pb, 4.80% Zn over 1.45 m.  This is one of the most important geological indicators of a Source environment encountered to date at La Platosa; 
• Hole LP1000 drilled west of the 6A Manto intersected 756g/t (22.1 oz/T) Ag, 10.55% Pb, 24.11% Zn over 4.83 m.

Toronto, Ontario – April 13, 2012 - Excellon Resources Inc. (TSX:EXN) ("Excellon" or "the Company") Mexico’s highest grade silver producer, is pleased to report assay results for seven new drill holes.  Of the seven holes, six were directed to the search for additional massive sulphide manto mineralization.  Five were drilled west of the northwest corner of the 6A Manto and one was drilled immediately north of the northwest extremity of the Guadalupe Manto.  The seventh was drilled in the Rincón del Caído area 1.0 km northwest of the La Platosa Mine to further the search for the large-tonnage proximal source of the massive sulphide mantos.

John Sullivan, Vice President of Exploration, Mexico states; “We believe that the Platosa manto holes will contribute additional tonnage to the Mineral Resource in the future.  They are also important due to their proximity to existing underground infrastructure and will be worked into the short-medium term mining plan.”  He further added; “In addition we are very encouraged by the intersection in hole LP986.  It again demonstrates that the Rincón del Caído area holds considerable discovery potential and validates our strategy as we continue to develop exploration targets for the source of the high-grade Platosa mantos.”

Mexican Exploration Update:
Assay details for the seven holes are shown in the table below.  Locations for the six manto holes are shown on Map 2.  The Rincón del Caído area with holes LP986 and LP763, drilled in 2010, is shown on Map 3.  All intervals are estimated true thicknesses.  In addition to these seven holes there have been 19 other holes, including one which was abandoned because of technical difficulties, drilled at Platosa since the exploration press release dated December 2, 2011.  While some of these 19 holes encountered sulphides, none intersected metal values of significance.

Two drills are currently operating at Platosa.  One continues the search for additional carbonate replacement deposit (“CRD”) massive sulphide mantos.  The other targets the large-tonnage proximal source of these mantos (“the Source”). 

With respect to other priorities, a Natural Source Audio Magnetotelluric (“NSAMT”) ground geophysical survey over selected portions of the Platosa Property is to begin before the end of April.

About Excellon
Excellon, a mineral resource company operating in Durango and Zacatecas States, Mexico, and Ontario and Quebec, Canada, is committed to building value through production, expansion and discovery.  Excellon is Mexico’s highest-grade silver producer; it produces silver, lead and zinc from the high-grade manto Mineral Resource on its large, 100% owned Platosa Property, strategically located in the middle of the Mexican CRD/silver belt. Excellon's focus is on expanding its operating capacity and increasing its Mineral Resources at Platosa where an exploration program focused on diamond drilling and advanced geophysical techniques is ongoing. The Platosa Property, not fully explored, has several geological indicators of a large mineralized system.  The Miguel Auza Mill Operation in Zacatecas also has 41,000 hectares of underexplored land.  Excellon also has ongoing gold exploration programs on the DeSantis Project, located near Timmins, Ontario and the Beschefer Project, located in northwestern Quebec.  Both these projects host gold mineralization and significant potential for the discovery of more.  Excellon will continue to use cash from operations to fund its ongoing exploration activities.
