Excellon Announces That Platosa Ramp Has Reached Mineralization.

TORONTO -- Excellon Resources Inc. (TSX VENTURE:EXN) is pleased to announce that the Platosa Ramp, on its 100% owned Platosa Property in Durango, Mexico has reached massive sulphide mineralization at approximately 670 metres down-ramp. The mineralization consists of massive galena and sphalerite with minor pyrite and carbonate gangue and lies right at the edge of the "4C Manto" Indicated Resource(i) as defined in the Roscoe Postle Associates Inc. ("RPA"), independent geological and mining consultants, N.I. 43-101 report of December 10, 2003 (report available at www.sedar.com) The 4C is the second largest of the mineralized bodies targeted for initial test mining and contains an Indicated Resource of 19,600 Tonnes grading 1,276 g/T Ag (37 oz/T Ag); 11.1% Pb, and 16.4% Zn. Continuous channel sampling of the present face has been done and assays are pending, but visual comparison indicates that grades will be similar to those for the drillholes that define the 4C Manto. Strong sulphides were also encountered approximately 15 metres up-ramp to the south and are believed to be an offshoot of the 4C developed on a strong NW-SE structure. Some 200 tonnes of development muck generated from cutting through these sulphides was stockpiled for shipment.

Now that the first of the seven principal bodies defined as Indicated Resources(i) has been reached, the ramp will continue to depth to develop the 5A Manto, the largest and highest grade body known to date on the property. The 5A Manto contains 24,500 Tonnes grading 3,912 g/T Ag (114 oz/T Ag); 22.3% Pb and 6.5% Zn. The 5A lies approximately 20 metres below the current ramp level and will require some 135 metres of additional ramping to reach. A ventilation raise has also begun which is expected to take approximately 2 weeks to reach surface from the current ramp level. Full scale mining and underground drilling will begin once the raise is completed and appropriate ventilation is established.

Excellon's Chairman, Richard Brissenden, said: "We are absolutely delighted to be in mineralization at last, and are additionally pleased to have also encountered significant mineralization well outside the currently defined Indicated Resource, since this will likely add significantly to our tonnage. This is typical of Manto orebodies throughout Mexico and we expect that similar offshoots will be found along the margins of most of our mantos. We plan to continue driving into the heart of the 4C Manto to bring it into full-scale production within the next few weeks."

The Platosa 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. Assaying and check-assaying is being performed by ALS-Chemex Laboratories of Vancouver and BSI Inspectorate of Reno, Nevada. Engineering design and supervision of the test mining program has been executed by RPA. Mine development is being done by Puertos y Tuneles S.A. de C.V. of Queretaro, Mexico under the direction of Joy Merz, Platosa Mine Manager.

(i)Readers are cautioned that mineral resources that are not classified as mineral reserves do not have demonstrated economic viability.
