Excellon Announces Discovery of New Zone of Sulphides and Appointment of New Director.

TORONTO -- Excellon Resources Inc. (TSX VENTURE:EXN) is pleased to announce the discovery of a new zone of sulphides lying 450 metres (m) northeast from the closest known mineralization on its 14,692 hectare (35,000 acre) Platosa/Saltierra Property in Durango, Mexico. Excellon is also pleased to report continuing extension of the N-1 Manto discovered in December 2004 and to provide a progress report on development of the ramp on its 100% owned Platosa Core area. Finally, Excellon is pleased to announce that Mr. Andre Yves Fortier joined the Company's board of directors as of March 14, 2005.

Excellon extends ramp to 611 m from portal

As of Wednesday, March 16, the 4 by 4.5 metre Platosa Ramp, which commenced on September 1, 2004, had advanced 611 m from the portal. Based on an updated mine plan, the ramp is expected to reach mineralization in April 2005 if the current rate of progress continues (see Map). Underground exploration drilling is expected to begin as soon as a ventilation raise, presently under construction, is completed.

Excellon discovers new sulphide zone

Excellon's aggressive surface drilling program (see Press Release of January 20, 2005) has found a new zone of sulphide mineralization lying 450 m to the northeast of Manto 6, the closest mineralization known on the property (Table 1, Map below). This new zone, named the NE-1, lies along the projection of the structural trend that contains the principal sulphide mantos targeted for production. The targets were drilled on coincident Natural Source Audio Magneto Tellurics ("NSAMT") geophysical and biogeochemical anomalies. All three holes drilled in this area cut sulphides. Hole LP-114 cut 0.77 m of sphalerite-rich mineralization, averaging 27% zinc, at 219 m depth. Hole LP-115 was drilled 10 m to the northeast of LP-114 and cut 2 m of galena and fluorite bearing dolomite breccia, including .77 m grading 88 g/T silver (2.8 oz/T) and 2.8% lead at 224 m depth. Hole LP-119 was drilled 10 m to the north of LP-114 and cut 20 cm galena and fluorite bearing dolomite breccia at 216 m depth. Results for LP-114 and LP-115 are presented below; assays for LP-119 are pending. The intercepts indicate a pattern of deepening and thickening mineralization and additional drilling is being designed to follow this trend.

Excellon continues to extend N-1 Manto

Drilling also continues to add to the new N-1 Manto that lies 85 to 125+ m northwest of the known resources (see Press Release of January 20, 2005) (Table 1, Map below). Drillholes LP-116 and LP-117 were drilled 10 and 20 m north, respectively, from LP-106 on the northern flank of the N-1 Manto. Both holes hit galena and sphalerite-rich massive and brecciated sulphides with grades and thickness comparable to those reported previously from this manto. Hole LP-118 was drilled 10 m southwest of LP-107 and cut trace sulphides. Notably, the LP-117 intercept also contains nearly 1 g/T of gold. This brings to 10 the total number of contiguous sulphide bearing holes in the N-1, the volume and grade of which is being calculated by Roscoe Postle Associates Inc., independent geological and mining consultants ("RPA"). Evaluation of how to incorporate this emerging mineral resource into the mine plan contained in the RPA report of December 10, 2003 (report available at www.sedar.com) is underway.

Both the NE-1 and the N-1 Mantos remain open in several directions and are slated for additional drilling. Further drilling of the N-1 will probably largely be done from underground once access to this area is achieved from the Platosa Ramp.

LP-113 was drilled 25 m from the northeast end of Manto 6 on an Induced Polarization ("IP") geophysical anomaly generated by the Mexican Geological Survey. It cut only trace sulphides and further IP work is not contemplated.

Assaying and check-assaying is being performed by ALS-Chemex Laboratories of Vancouver and BSI Inspectorate of Reno, Nevada. Check assays for these holes are pending, but results are historically consistent between the two laboratories. Drilling has been done by Major Drilling of Mexico. The drillhole map below is also available in colour on the company website at: www.excellonresources.com, or by request.

The ongoing exploration program is designed and supervised by Mr. A. D. MacKenzie, P. Eng., and Dr. Peter Megaw, respectively Excellon's President, and its Consulting Geologist and Exploration Manager of its Mexican subsidiary.

Other exploration

Other recent exploration work includes initiation of 1:5,000 geologic mapping of the entire Sierra Bermejillo and completion of another 15 line-km of NSAMT geophysics. These surveys, focused on covered areas flanking the Platosa Mine area and more remote target areas throughout the range, now total nearly 40 km. A number of geophysical anomalies that coincide with the projections of surface mappable structures with associated mineralization and alteration have been defined and drilling targets, lying from 1 to 5 km distant from the Platosa Deposit, are being developed for testing in the near future.

Qualified Person and Quality Assurance and Control

Dr. Peter Megaw, Ph.D., C.P.G., has acted as the Qualified Person as defined in National Instrument 43-101, for this disclosure and supervised the preparation of the technical information on which this release is based. Dr. Megaw has a Ph.D. in geology and more than 20 years of relevant experience focused on silver and gold mineralization, and exploration and drilling in Mexico. He is a Certified Professional Geologist (CPG 10227) by the American Institute of Professional Geologists and an Arizona Registered Geologist (ARG 21613). Dr. Megaw is not independent of Excellon as he is a shareholder and his company receives a Finder's Fee with respect to the Platosa/Saltierra property.
