TORONTO, ONTARIO--(Marketwire - June 10, 2008) - Excellon Resources Inc. (TSX:EXN) has successfully sealed the water inflow that occurred during the development of a new ventilation raise at its Platosa operation in Durango State, Mexico. In addition to sealing the inflow area, the Company placed a concrete safety barrier in the access drift to the raise during the grouting process. Drill testing has verified the integrity of both the plug in the raise and the barrier in the drift. The Company has begun to dewater the mine, and will release a further update once normal operations have resumed.

"Excellon's operations team has proved itself capable of handling this unexpected event, and I expect normal operations to resume shortly," said Peter A. Crossgrove, Excellon's chairman.
