Excellon Announces Additional High-Grade Holes in the Pierna Manto

1,489 g/t (43 oz/T) Ag, 10.65% Pb, 21.63% Zn over 6.10 m in hole EX10-LP875

TORONTO, ONTARIO, Nov. 17, 2010 (Marketwire) -- Excellon Resources Inc. (TSX:EXN) is pleased to announce assay results for two additional holes from what company geologists believe may be a new, high-grade manto discovered between the Rodilla and NE-1 mantos. Tentatively named the Pierna Manto, this massive sulphide zone is related to a northwest-southeast trending structure and is open to the northwest. Hole LP875 intersected 6.10 metres (m) of massive sulphides grading 1,489g/t (43 oz/T) Ag, 10.65% Pb, 21.63% Zn. Hole LP876 intersected 7.60 m grading 612 g/t (18 oz/T) Ag, 8.07% Pb, 14.47% Zn. Three holes in the same zone and with similar high grades were disclosed in a press release dated November 4, 2010.

These results again provide evidence of the discovery potential for important additional distal carbonate replacement deposit (CRD) resources in and close the immediate Platosa Mine area.

"We continue to be very encouraged by the discovery of such significant massive sulphides at Platosa. A new discovery such as this can have an important impact on the manner in which we develop the Platosa Mine and opens up new areas for detailed exploration," said John Sullivan, Excellon's Vice-President of Exploration.

Assay intersection details for holes LP875 and 876 are shown in the table below and on the accompanying drill hole location map. All intervals are estimated true thicknesses. In addition to these two holes there has been one other hole drilled at Platosa since the exploration press release dated November 4, 2010.

Excellon's drill core samples are prepared and assayed by SGS Minerals Services (SGS) in Durango, Mexico. The lab is accredited to ISO/IEC 17025. The Company has a comprehensive QAQC program, supervised by an independent Qualified Person.

About Excellon

Excellon, a mineral resource company operating in Durango and Zacatecas States, Mexico, is committed to building value through production, expansion and discovery. Excellon is producing silver, lead and zinc from the high-grade manto Mineral Resource on its large Platosa Property, strategically located in the middle of the Mexican 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 equally large Miguel Auza property hosts an Indicated and Inferred Mineral Resource and was the site of considerable historic mining for silver, (gold), lead and zinc. The exploration potential of Miguel Auza remains to be fully evaluated and an initial exploration program, the results of which remain to be fully evaluated, has recently been completed.
