Excellon announces updated NI 43-101 resource estimate maintains high-grade mineral resource at Platosa Mine, Mexico07:00 EDT Tuesday, October 25, 2011 Toronto Stock Exchange - EXN TORONTO, Oct. 25, 2011 /PRNewswire/ - Excellon Resources Inc. (TSX:EXN) ("Excellon" or "the Company") is pleased to report the results of the updated Mineral Resource estimate (as at July 31, 2011) for its 100%-owned Platosa Mine located in Durango State, Mexico. The results meet Company expectations and the Platosa Mine remains one of the highest grade producing Ag, Pb, Zn deposits in Mexico. Highlights: New Measured plus Indicated Mineral Resource: 637,000 tonnes (t) grading 836 g/tonne (24.4 oz/Ton (T)) Ag, 8.95% Pb, 10.58% Zn;  Measured plus Indicated tonnage increased by 10% from that of the previous estimate (October 31, 2009); Lead and Zn grades are nearly unchanged while the Ag grade has decreased by 8% as most of the added tonnes have a lower Ag grade than those mined since late 2009.  New Inferred Mineral Resource estimate is 69,000 tonnes grading 1,011 g/t (29.5 oz/T) Ag, 11.35% Pb, 11.34% Zn.  Inferred Ag, Pb and Zn grades increased significantly while tonnage decreased, both as a result of an increased Net Smelter Return (NSR) cut-off value being used in the 2011 estimate.  The new estimate confirms that the Mineral Resource at Platosa has been maintained since the previous estimate as at October 31, 2009.  Taking into account the 109,000 tonnes of production since the previous estimate, total tonnage increased by 10%.  The increase in tonnage is derived largely from the Pierna, 6A/6B and NE-1 Mantos.  The high-grade Pierna Manto, discovered in late 2010, contributed a Measured plus Indicated Mineral Resource of 45,000 tonnes grading 776 g/t (22.6 oz/T) Ag, 8.80% Pb, 15.94% Zn. The new tonnages and grades are summarized in the following table and the new manto outlines are shown on the plan map below.

Mineral Resources are estimated at an incremental NSR cut-off value of US$200 per tonne NSR metal price assumptions: Ag US$25.00/oz, Pb US$1.15/lb, Zn US$1.15/lb. Estimate is of Mineral Resources only and, because these do not constitute Mineral Reserves, they do not have any demonstrated economic viability. National Instrument 43-101 compliant Mineral Resource estimate prepared by David Ross, P.Geo., of Roscoe Postle Associates Inc., independent geological and mining consultants of Toronto, Ontario.  Prepared as at July 31, 2011. Totals may not add correctly due to rounding. Jeremy Wyeth, President and CEO states, "Our new NI 43-101-compliant Mineral Resource estimate confirms that our drilling program in the immediate mine area, has allowed us to maintain and add to our resource on a continual basis, even as we have mined 109,000 tonnes of ore since the previous estimate.  Looking to the future, we remain committed to our aggressive exploration program and are confident that we remain on course to discover the high-tonnage proximal deposit, which is the source of the Platosa Manto system." Significant Estimation Parameters Mineral Resources are reported at an NSR cut-off value of US$200/tonne.  Assumptions used for the NSR calculation include metal prices of US$25.00/oz Ag, $1.15/lb Pb, and $1.15/lb Zn.  Block Ag, Pb and Zn grades were interpolated and constrained within the wireframe models using the Inverse Distance Squared method.  The Platosa drill hole database includes 955 vertical and inclined diamond drill holes totalling 204,736 metres of core.  Most holes within the Mineral Resource area are aligned along NE-SW oriented sections spaced 15 metres apart.  Average drill hole spacing is approximately 15 to 20 metres.  A total of 940 silver, lead and zinc assays were used in the Mineral Resource estimate.  Block tonnage was estimated from volume using a bulk density formula derived from the interpolated lead and zinc grades and a regression formula derived from 252 bulk density measurements made on mineralized drill core.  The estimate is of Mineral Resources only and, because these do not constitute Mineral Reserves, they do not have any demonstrated economic viability. A detailed description of the estimation and other pertinent geotechnical information related to the Platosa project will be included in an NI 43-101-compliant technical report being prepared for the Company by RPA and to be filed on SEDAR within the mandated 45 days of this press release. 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 in place a comprehensive QAQC program, supervised by an independent Qualified Person.
